We Have Met The Enemy...

Image Source: Good Reads


Topics: Economy, Education, Large Hadron Collider, LHC, Particle Physics, Politics


I openly and severely date myself once again (the $2.95 cover a dead giveaway), all honor to Walt Kelly coining it the first Earth Day, April 22, 1970. Next month will mark the 46th year we've observed it as science and intelligence have receded from public life.

We're great "gadget consumers": we've just become piss-poor producers.

The Superconducting Supercollider was formally in Waxahatchie, Texas. It's a whole in the ground now. That Higgs Boson discovered at CERN was supposed to be found in the good old US of A.

I sum the current state of affairs with science and the general public in my best "Me Tarzan; you Jane" personification:

- Real science BAD.

A primitive grunt, but a personification of the aftermath attacking the education enterprise in this country (vis-à-vis the lucrative teaching-to-the-test industry), and education's absolute necessity in running a democratic republic successfully. We've played chicken with conspiracy provocateurs, climate change deniers, Flat Earth groups, science deniers, vaccine deniers, Young Earth groups and the denial of human self-government itself. These "chickens have come home to roost" (Malcolm X).

Physics and Physicists* had a good blog entry last Friday on the Socio-Economic Impact of the LHC, based on an analysis posted in Physics arXiv (link below). It answers the question "what's in it for me" for Jane and Joe Q. Public, who have to "catch the vision" and support any research typically with their tax dollars, a far better and lasting investment than the boondoggle of sports stadiums.

Like "Zapper Z*" says (the particular physicist's online persona), it's like we don't care, or many of us have been exquisitely conditioned not to care.

Even worse, do we think modern society and its reliance on technology is a combination of fairies, pixie dust, microwave popcorn, three heel clicks of ruby red shoes to Kansas, and a genie with three wishes? It explains our current crisis of governance that one of the front runners seeking the nuclear codes has a LOT more in common with The Kardashians than we'd all care to admit. 


..."and he is 'us.'"

Abstract

In this paper we develop a cost-benefit analysis of a major research infrastructure, the Large Hadron Collider (LHC), the highest-energy accelerator in the world, currently operating at CERN. We show that the evaluation of benefits can be made quantitative by estimating their welfare effects on different types of agents. Four classes of direct benefits are identified, according to the main social groups involved: (a) scientists; (b) students and young researchers; (c) firms in the procurement chain and other organizations; (d) the general public, including onsite and website visitors and other media users. These benefits are respectively related to the knowledge output of scientists; human capital formation; technological spillovers; and direct cultural effects for the general public. Welfare effects for taxpayers can also be estimated by the contingent valuation of the willingness to pay for a pure public good for which there is no specific direct use (i.e., as non-use value). Using a Monte Carlo approach, we estimate the conditional probability distribution of costs and benefits for the LHC from 1993 until its planned decommissioning in 2025, assuming a range of values for some critical stochastic variables. We conservatively estimate that there is around a 90% probability that benefits exceed costs, with an expected net present value of about 2.9 billion euro, not considering the unpredictable applications of scientific discovery.

Space Weather...

Huge solar coronal mass ejections hurl plasma into space. These cause space storms that can wreak havoc on Earth.


Topics: Heliophysics, International Space Station, NASA, Space, Space Exploration


Auroras lit the skies as far south as Cuba on September 1, 1859. Telegraph systems across the globe malfunctioned, sparking and shocking their operators, and making transmission impossible. The cause was a massive geomagnetic storm, known as the Carrington Event after astronomer Richard Carrington, who observed an enormous solar flare preceding the events on Earth.

If a storm of equal strength occurred in today’s technology-addicted world, it would have catastrophic impacts, said a panel of space weather experts at the American Association for the Advancement of Science (AAAS) Meeting in Washington, DC on February 15.

“This was by all measures a huge storm,” said Daniel Baker of the University of Colorado. “If an event of that size were to occur today, the effects by most estimates would be devastating.” Large regions of the globe could be plunged into darkness and hobbled with technology failures, from widespread power outages, to loss of communication systems, to GPS navigation failures, and damage to satellites.

Staircase Avalanche Photodiode...

Citation: Appl. Phys. Lett. 108, 081101 (2016); http://dx.doi.org/10.1063/1.4942370

Topics: Electronics, Photonics, Semiconductor Technology, Quantum Mechanics

An avalanche photodiode is a semiconductor-based photodetector (photodiode) which is operated with a relatively high reverse voltage (typically tens or even hundreds of volts), sometimes just below breakdown. In this regime, carriers (electrons and holes) excited by absorbed photons are strongly accelerated in the strong internal electric field, so that they can generate secondary carriers, as it also occurs in photomultipliers. The avalanche process, which may take place over a distance of only a few micrometers, for example, effectively amplifies the photocurrent by a significant factor. Therefore, avalanche photodiodes can be used for very sensitive detectors, which need less electronic signal amplification and are thus less susceptible to electronic noise. However, the avalanche process itself is subject to quantum noise and amplification noise, which can offset the mentioned advantage. The excess noise is quantified with the excess noise factor F, which is the factor by which the electronic noise power is increased compared with that of an ideal photodetector. *



* Encyclopedia of Laser Physics and Technology: Avalanche Photodiodes


Abstract

Over 30 years ago, Capasso and co-workers [IEEE Trans. Electron Devices 30, 381 (1982)] proposed the staircase avalanche photodetector (APD) as a solid-state analog of the photomultiplier tube. In this structure, electron multiplication occurs deterministically at steps in the conduction band profile, which function as the dynodes of a photomultiplier tube, leading to low excess multiplication noise. Unlike traditional APDs, the origin of staircase gain is band engineering rather than large applied electric fields. Unfortunately, the materials available at the time, principally AlxGa1−xAs/GaAs, did not offer sufficiently large conduction band offsets and energy separations between the direct and indirect valleys to realize the full potential of the staircase gain mechanism. Here, we report a true staircase APD operation using alloys of a rather underexplored material,AlxIn1−xAsySb1−y, lattice-matched to GaSb. Single step “staircase” devices exhibited a constant gain of ∼2×, over a broad range of applied bias, operating temperature, and excitation wavelengths/intensities, consistent with Monte Carlo calculations.

Unexpected and Unsung Black Movie Actors

(CNN) Dripping with menace, the alien in Ridley Scott's 1979 space horror classic was quite literally the movie's break-out star.

With an extendable jaw that salivated acid, it wasn't enough that "Alien" could capture and kill; it wanted to use humans unfortunate enough to cross its path as a surrogate womb as well.

Yet while enthusiasts know much about the film's cast -- its heroine Ripley, played by Sigourney Weaver, and the unfortunate crew of the spaceship Nostromo -- the man behind the titular creature was nearly as elusive as his enduring on-screen character.

III-V Semiconductor Superlattices...

FIG. 1.

Even between lattice-matched crystalline materials, there exist nonuniform transition layers that behave as an effective atomic-scale interface roughness with some rms height Δ. This effective interface roughness leads to phonon-momentum randomization and to interface resistance in cross-plane transport.
Citation: J. Appl. Phys. 118, 175101 (2015); http://dx.doi.org/10.1063/1.4935142

Topics: Applied Physics, Materials Science, Nanotechnology, Phonons, Semiconductor Technology, Solid State Physics, Thermodynamics

Abstract


This paper presents a semiclassical model for the anisotropic thermal transport in III-V semiconductor superlattices(SLs). An effective interface rms roughness is the only adjustable parameter. Thermal transport inside a layer is described by the Boltzmann transport equation in the relaxation time approximation and is affected by the relevant scattering mechanisms (three-phonon, mass-difference, and dopant and electron scattering of phonons), as well as by diffuse scattering from the interfaces captured via an effective interface scattering rate. The in-plane thermal conductivity is obtained from the layer conductivities connected in parallel. The cross-plane thermal conductivity is calculated from the layer thermal conductivities in series with one another and with thermal boundary resistances (TBRs) associated with each interface; the TBRs dominate cross-plane transport. The TBR of each interface is calculated from the transmission coefficient obtained by interpolating between the acoustic mismatch model (AMM) and the diffuse mismatch model (DMM), where the weight of the AMM transmission coefficient is the same wavelength-dependent specularity parameter related to the effective interface rms roughness that is commonly used to describe diffuse interface scattering. The model is applied to multiple III-arsenide superlattices, and the results are in very good agreement with experimental findings. The method is both simple and accurate, easy to implement, and applicable to complicated SL systems, such as the active regions of quantum cascade lasers. It is also valid for other SL material systems with high-quality interfaces and predominantly incoherent phonon transport.

How Much For Half The Planet...

Image Source: First link, first paragraph


Topics: Diversity in Science, Existentialism, Humor, Science Fiction, Star Trek


I use a derivation of TOS novel, "How Much for Just the Planet?" in the title of this post. Captain Kirk and some Klingons were in brinkmanship (United Federation of Planets = USA; Klingons = Soviets - Cold War, got it?) over Dilithium Crystals (an important commodity in 23rd Century economy for the whole warp drive thing). Lithium exists; dilithium just sounded uber cool, I think. Zephram Cochran apparently did it with good old Earth tech and a CD from Steppenwolf. The article reminded me of it.

The NASA endeavor at its essence ultimately is to avoid a H.E.L.E. - better known as a human extinction level event - a term I was introduced to in the miniseries Heroes Reborn, and the dizzying pseudo paradoxes of teleportation, time travel, self-cloning, telepathy and consciously occupying video games. Er...it has to do with EVOs - a group of humans with evolutionary extraordinary powers, and like most science fiction/modern myth asks questions about humans, humanity, xenophobia and society similar to the X-men (a metaphor for African Americans during the Civil Rights Movement):  Charles Xavier née Martin Luther King; Magneto, Malcolm X.

As I'm apt to ask (I did mentally in "Interstellar"): who flies off to the Moon, Mars or Alpha Centauri for the species to survive; who goes to the other half of the planet for the species to survive? And, where exactly is the other half of the planet that's "desirable," and protected/isolated from the effects of climate change?



It may boil down sadly to: 1. Who has trained in a STEM field; 2. Who can afford it.

Edward O. Wilson sees mass extinction of species “among the deadliest threats that humanity has imposed on itself.”

Invoking the kilometers-wide object that struck Earth some 66 million years ago, Edward O. Wilson calls the extinction rate humans are imposing in the biosphere “the equivalent of a Chicxulub-sized asteroid strike played out over several human generations.” His 32nd book, Half-Earth: Our Planet’s Fight for Life, comes out this month. The New York Times and other media have begun reporting the solution it advocates: reserving half the planet to let other species survive and flourish.

Claudia Dreifus writes for the Times’s science section and teaches at Columbia University’s School of International and Public Affairs. In an Audubon Magazine piece, she reminded readers about Wilson’s scientific and public stature:

At 86, Edward Osborne Wilson, Harvard University research professor emeritus of comparative zoology, is among the most famous scientists of our time. Only Jane Goodall and Stephen Hawking can draw a larger crowd. Over the decades he’s made his mark on evolutionary biology, entomology, environmentalism, and literature. In all there have been 31 books, two of which, On Human Nature and The Ants, received the Pulitzer Prize.

She added that he’s widely accepted as “one of the greatest researchers, theorists, naturalists, and authors of our time,” is “known as the father of the concepts of sociobiology and biodiversity,” and is “highly celebrated for his lifetime of environmental advocacy.” Concerning the forthcoming book, she explained that it’s “his answer to the disaster at hand: a reimagined world in which humans retreat to areas comprising one half of the planet’s landmass.” She continued: “The rest is to be left to the 10 million species inhabiting Earth in a kind of giant national park. In human-free zones, Wilson believes, many endangered species would recover and their extinction would, most likely, be averted.”

An interdisciplinary team of scientists has worked out a way to make electric vehicles that are not only carbon neutral, but carbon negative, capable of actually reducing the amount of atmospheric carbon dioxide as they operate.

They have done so by demonstrating how the graphite electrodes used in the lithium-ion batteries that power electric automobiles can be replaced with carbon material recovered from the atmosphere.

The recipe for converting carbon dioxide gas into batteries is described in the paper titled "Carbon Nanotubes Produced from Ambient Carbon Dioxide for Environmentally Sustainable Lithium-Ion and Sodium-Ion Battery Anodes" published in the Mar. 2 issue of the journal ACS Central Science.

The unusual pairing of carbon dioxide conversion and advanced battery technology is the result of a collaboration between the laboratory of Assistant Professor of Mechanical Engineering Cary Pint at Vanderbilt University and Professor of Chemistry Stuart Licht at George Washington University.

NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko headed back toward Earth on Tuesday after nearly a year aboard the International Space Station, ending a record-long U.S. spaceflight intended to pave the way for human travel to Mars.

The men, accompanied by Russian cosmonaut Sergey Volkov, strapped themselves inside a Russian Soyuz capsule and departed the station at 8:02 p.m. EST (0102 GMT on Wednesday).

They are expected to make a parachute landing in Kazakhstan at 11:25 p.m. EST (0425 GMT on Wednesday).

Kelly and Kornienko have been aboard the space station for 340 days, about twice as long as previous crews. Their flight sets a record for the space station and for the longest U.S. space mission.

*Here's another background story on America's issue with nuclear waste from The Waste Lands Report*

By Keith Rogers
Las Vegas Review-Journal
Posted October 27, 2015 - 3:32pm Updated October 27, 2015 - 5:29pm


Yucca Mountain Project opponent Richard Bryan said Tuesday he was "stunned" when he watched a video of small explosions that followed more powerful ones Oct. 18 at a low-level nuclear waste dump near Beatty.

He said explosions and fire at the now-closed, state-owned landfill at the US Ecology site that shut down a 140-mile stretch of U.S. Highway 95 for nearly 24 hours added to his concerns for federal plans to haul 77,000 tons of spent nuclear fuel assemblies and high-level waste to Yucca Mountain, 100 miles northwest of Las Vegas.

"We've already got kind of a glimmer of what can happen with low-level. ... This stuff is highly dangerous," Bryan, chairman of the Nevada Commission on Nuclear Projects, said following one of 70 press conferences held at cities nationwide on nuclear waste transportation.

As of Tuesday, investigators still had not released the cause of the blasts nor the material that burned or ended up on the ground nearby, although preliminary test indicated there was no radiation problem on the surface.

The simultaneous press conferences organized by the nonprofit Nuclear Information and Resource Service — a networking center based in Takoma Park, Md., for people concerned about nuclear power and radioactive waste — had been planned before the soil cap of Trench No. 14 at the dump, 10 miles south of Beatty, exploded after heavy rains. Beatty is about 117 miles northwest of Las Vegas.

Bryan seized the opportunity, though, to draw a parallel.

"I thought to myself, if that's possible with low-level. This is the stuff that's supposed to be marginally dangerous, not to worry. We open a trench and put it in there. I was stunned. And the fact that you've now got to block the major highway between Las Vegas and Reno. Imagine if that blockage was between Las Vegas and Los Angeles," he said.

"Would that have had an impact that could be devastating to a community?" asked Bryan, a former governor and U.S. senator.

Bryan, for the press conference, shared a balcony at the Molasky Building overlooking the Spaghetti Bowl with Las Vegas Mayor Carolyn Goodman and Judy Treichel, executive director of Nevada Nuclear Waste Task Force.

A preliminary state fire marshal's report on the Oct. 18 Beatty incident says US Ecology General Manager Bob Marchand took the video that state officials later released to the Las Vegas Review-Journal.

Marchand and a security officer heard "sounds of bangs," then saw smoke "coming from a fenced area labeled Radioactive Materials. They also observed debris ejecting out of the crater fifty to sixty feet into the air. This occurred for several hours," according to the report by officer Martin Azevedo. Several damaged 55-gallon drums were found around the crater and two were outside the fence.

Tim Judson, executive director of the Nuclear Information and Resource Service, said the timing of nationwide press conferences coincided with release of new maps that show population centers plotted by the center's researchers along "representative routes" that the Department of Energy has proposed for hauling nuclear waste to Yucca Mountain by trains and trucks.

In addition, he said there has been increased motivation in Congress to rejuvenate the funding-starved Yucca Mountain Project that the Obama administration abandoned in 2010 to explore alternatives for nuclear waste disposal.

Fred Dilger, a Nevada consultant, said there has been a recent "drive among pro-nuclear folks to dismiss transportation risks. We think they have to do a lot better to move this safely."

The Nuclear Information and Resource Service estimates more than 10 million people will be exposed to small doses of radiation along transportation routes that would involve 2,800 rail shipments and 2,700 truck shipments.

*MY TAKE: Therein lies the issue. We need to have more containment facilities, but we also have to find the most economical and again, safest way to transport the material. How much risk are Americans willing to absorb including possible radiation to move this waste to those facilities? The pro-nuclear folks have to pump their brakes and make sure to analyze the logistical safety concerns. Most Americans probably won't know or recognize what the cargo is in the trucks and railcars, but 70 cities and their communities represent a lot of possible challenges. This is one sticky issue for America. I pray to God they get it right sooner than later.

Richard Bryan, chairman of the Nevada Commission on Nuclear Projects, speaks during a nuclear waste transportation summit news conference at Molasky Building Tuesday, Oct. 27, 2015, in Las Vegas.

Tetraquark Discovery...

Four flavours: X(5568) has no charm quark/antiquark pair. (Courtesy: Shutterstock/paul_june)

Topics: Particle Physics, Quantum Mechanics, Quarks, Theoretical Physics


A new particle that is a bound state of four different flavours of quarks has been discovered by physicists working on the DØ experiment at Fermilab *. Called X(5568), the particle has a mass of about 5568 MeV/c2, and appears to contain "up" and "bottom" quarks as well as "down" and "strange" antiquarks.

Although other tetraquarks have previously been identified, X(5568) is the first in which all of the quarks have different flavours, which could affect our understanding of how quarks interact with each other. The discovery is also notable because X(5568) is produced at a much higher rate in proton–antiproton collisions than had been expected.

The particle was discovered by sifting through data acquired by DØ – an experiment that ran at Fermilab's Tevatron proton–antiproton collider from 2002 to 2011. The statistical significance of the discovery is 5.1σ, which puts it just above the 5σ required for a discovery in particle physics.

*  *  *  *  *

* And the X(5568) is not just any new tetraquark. While all other observed tetraquarks contain at least two of the same flavor, X(5568) has four different flavors: up, down, strange and bottom.

“The next question will be to understand how the four quarks are put together,” says DZero co-spokesperson Paul Grannis. “They could all be scrunched together in one tight ball, or they might be one pair of tightly bound quarks that revolves at some distance from the other pair.”

Four-quark states are rare, and although there’s nothing in nature that forbids the formation of a tetraquark, scientists don’t understand them nearly as well as they do two- and three-quark states.

This latest discovery comes on the heels of the first observation of a pentaquark—a five-quark particle—announced last year by the LHCb experiment at the Large Hadron Collider.

This week’s discussion topic is Cyberfunk and the subgenres Cypherfunk and Biofunk. The definitions of the three Categories of African American speculative science fiction is as follows

Cyberfunk - Like the genre from which it gains inspiration, Cyberpunk, Cyberfunk is a genre of Speculative Fiction centered on the transformative effects of advanced science, information technology, computers and networks (“cyber”) coupled with a breakdown or radical change in the social order. Unlike Cyberpunk, however, Cyberfunk is expressed through an Afrikan / Black lens (“funk”). Often possessing a dark, gritty and cynical tone, Cyberfunk includes elements of Film Noir, hard-boiled Detective Fiction and postmodern deconstruction.

Cypherfunk - is any African activist advocating widespread use of strong cryptography, the art of writing or solving codes as a route to social and political change. Cypherfunkateers communicate through some type of online electronic mailing list, informal groups aimed to achieve privacy and security through proactive use of cryptography. Cypherfunks as with their Cypherpunk counterparts, have been engaged in an active movement since the late 1980s.

Biofunk - is a subgenre of African American speculative science fiction that focuses on biotechnology. It is derived from cyberpunk/cyberfunk, but focuses on the implications A derivative of cyberfunk involving bio-hackers, mega-corporations, and oppressive government agencies that manipulate human DNA. Most often keeping with the dark atmosphere of cyberfunk, biofunk generally examines the dark side of genetic engineering and represents the low side of biotechnology. Common ideas of this sub-genre are biotechnologies in the context of the gap between the rich and poor, the value and nature of life and humanity, human enhancement, misusage of biotechnologies for social control and profit.

The Questions I pose to my creative writers and artists are:

1) Out of these three sci-fi genres defined above, which could bring forth greater creative expression, storytelling, timing, design and environment in your work?
2) Since the beginning of Black History Month we have discussed AFROFUTURISM, ROCOCA, STEAMFUNK, and DIESELFUNK. Which combination with CYBERFUNK (or any of its subgenres) would inspire creative motivation and why?

For me, I believe the BIOFUNK genre appeals to my creative energies best because it is the most diverse, subjective and timeless. Stories of cures for cancer, AIDS, mental illness and other more HUMAN issue can be addressed. I believe I could communicate the character’s anxiety of self, society and/or corporate misuse, through mood and relating it with the struggles african americans on both north and south continental scale. My second choice would be creating a CYPHERFUNK story. It would be a “challenge” but I am attracted to the idea of motivating social change through African centered GLYPHS, codes and the world wide web.

If I ever enter into a project involving a combination of genres, I believe my first choice would be a time traveling CYPHERFUNK/CYBERFUNK story. The characters would travel through time somehow to the STEAMFUNK era and for some unfortunate reason one of them would be trapped there for a minute. A bit “Octavia Butler” - ish, yes I know but I believe I could swing it to make it completely different yawn. Well, hopefully more than a yawn…. LOL.

Your thoughts, creative BSFS friendz, fanboiz and fangirlz, Afrikanist and Five per Centerz!

The Battle Roar of Sekhmet

Egypt, 1350 BC

I entered the sanctuary area at the back of our hut with a bowl of gazelle meat. Beside me my niece, little Nebet, hugged her miniature drum as if it were a doll. The likenesses of our forefathers and mothers watched our passage with painted eyes, their altars adorned with weapons and the gold flies their valor had earned them in life. But it was the gilded likeness of Sekhmet, she of the lion mask and blood-dyed gown, who awaited our arrival against the wall. Despite the dimming of the sunlight through our hut's narrow windows, Sekhmet's amber eyes blazed with the same fire that had emboldened generations of our ancestors.

Many times I had knelt before her as I did now, lighting the meat I laid at her feet. The scent of its burning recalled battle after battle of blazing tents and enemies being speared, shot, or cleaved into pieces. The warmth channeled the sun’s blazing heat, which glossed my dark brown skin with perspiration. Even the crackling of flesh breaking down into ash became the cracking of bones and shields as I yelled the battle roar of Sekhmet in my memories.

This evening I would consult our matron for a different battle. This time, our enemies were not Kushites with ochre-reddened hair and leopard-belted kilts. Nor were they easterners like the Hittites or Babylonians, with light-skinned faces and loosely curled beards. No, they were Egyptians like ourselves, fellow children of the Black Land who had fallen under the influence of the false Pharaoh Akhenaten.

Already they had dragged little Nebet’s father away to slave away in the lair that tyrant had built for himself and his cult of lies. I did not even want to guess what his minions had done to her mother. Only I remained to protect and teach the girl over the past year, and never would I let her suffer the same fate as her parents.

I gave her a nod and she pounded her drum with more unbridled passion of a temple ensemble. Together we sang our prayer for Sekhmet’s vigilance, for her guidance, for the courage with which she would imbue us in the face of war and persecution. The fire on my offering continued to flicker on our ancestors’ faces as their spirits’ voices joined ours in a greater chorus. The thumping of my heart became a rhythm complementing Nebet’s drum, as did the war drums that had thundered before all my past battles. Alongside the music’s growing fury there rose an energy within me that flamed as hot as Sekhmet’s gaze. As she opened her jaws to bare her fangs in my vision, so did I.

It built up from my breast to my throat, ready to be released over a climax of cracking drums and shrieking cries.

Instead came the hoarse bray of a royal trumpet. Then followed silence, and finally the rapping of a bony knuckle on our door.

Nebet embraced the drum with shivering arms. I murmured to her that it would turn out all right, for you could never tell a frightened child anything else. Even I didn’t want to believe otherwise.

Outside the door, as expected, awaited Vizier Ay with his leopard-skin mantle, accompanied by royal guards with spears and cow-hide shields. He greeted me with the usual sneer on his dark, wrinkled date of a face, and the night-black dreadlocks of his wig clashed with the scruffy white stubble around his mouth. But judging from the way his eyes ran up and down my figure, he had more than uppity pride spreading that filthy smile of his.

“Well, well, if it isn’t Egypt’s distinguished champion, Takhaet,” Ay croaked. “I understand you’ve earned yourself a whole swarm of flies, yet your beauty remains unworn after so much combat.”

I scoffed. “Most men say my beauty is enhanced by that. But maybe strong women are too much for you to handle, old Vizier.”

“Don’t you dare disrespect a servant of Pharaoh, young lady!” The Vizier spat into my face and banged his staff against the dirt road. “This business is so important, may I inform you, that defiance could cost you your very life---or your adorable little niece’s. Tell me, O Takhaet, was it to our Aten that you were praying to?”

If I were to lie, I could spare myself and Nebet whatever this ancient monster and his master had planned for us. But I could not deny our lyrics had named Sekhmet rather than Akhenaten’s pet demon. Nor could I deny that our drumming had spoken in her favorite rhythms rather than any other god’s. And even if it would save my family, I could never betray the men and women of my village by pointing to them. A painful truth was better than a lie that hurt others.

“No, but it’s neither your business nor Akhenaten’s! You can prostrate before that devil you call Aten all you want, but you can never claw out your subjects’ deepest beliefs, no matter how you try!”

The sneer returned to Ay’s face. “But I can silence them. And I have, many, many times. Why, I must’ve…disciplined more commoners like you than all the barbarians you’ve ever slain, Takhaet. But, this time I’ll be diplomatic.”

I was not surprised when I saw one shriveled hand of his glide back and forth over his crotch. That gesture wrung my stomach like a wet rag inside.

“I know what you’re thinking, withered son of a jackal’s bastard. And I could rip out what remains of your manhood with my bare fist!”

The Vizier stepped back, cackling like a sickly hyena. “Excuse me, I didn’t mean that kind of deal. I meant something that would strike closer to your heart. Get the child!”

One of his soldiers shoved me aside, by happenstance touching the back of my hip, and marched into our hut. Nebet screamed and flailed her arms when he yanked her up between his arms.

“Isn’t this a sweet, plump young piece of crocodile bait!” he said. “Hopefully they’ll leave one piece for my supper!”

“You savage!” I lunged after him, but one of his comrades wrapped his arm around my neck and pulled me away.

“So what shall it be, O Takhaet? Your little Nebet or your loyalty to dead gods?”

I could not allow my niece, all that remained of my blood-kin, to fall into the clutches of men viler and more wretched than any Babylonian or Kushite I ever slew. Too many children, probably thousands, must have already been tossed to the crocodiles at Akhenaten’s behest. If either her father or mother still lived, only knowledge of their child’s survival could keep them going. Caving into Ay’s demands would keep her alive. It would also further fuel his swollen Vizier’s pride and embolden him to seek out more victims, more children to threaten and kill. Sekhmet could never die, but both Nebet and all the other children of Egypt could.

I answered his dilemma with a kick of my heel into my arrester’s shin.

Breaking myself free of his chokehold, I tore the knife out from under his belt and chucked it into the brow of Nebet’s captor. My niece hopped and clung onto my back even as I caught the soldier’s fallen spear and used it to pole-vault over the rest. On the other side waited Ay’s personal chariot. After knocking the driver out with the spear’s butt, I grabbed the reins and whipped the horses into a neighing gallop.

Driving the chariots was always my favorite part of battle.

Huts, villagers, and trees blurred past me. The wind blew in a cool gale against my face. I couldn’t help but yell with girlish glee as I relived the thrill of a chariot chase, even with all its bouncing jolts and veers.

Nebet, much to my joyful surprise, squealed and laughed with me. “Can we do this again sometime, Aunt Takhi?”

“Next time he comes, I promise!” I said.

Our fun ended with the bang of a thrown spear against the chariot’s wheel. It threw us into the sky over the skidding horses until we crashed onto a hut’s thatched roof. Only by the mercy of the old gods did I catch Nebet before she hit something harder.

Ay’s thugs encircled the hut and hurled more spears at us. As I dodged their throws with Nebet on my back, I observed we had reached the village’s edge. Beyond the outer palisade sprawled a grassy field with scattered acacias, which in turn gave way to forest on the horizon’s edge. The shelter under those trees would be our only hope.

I picked up another spear and vaulted from the roof, over the palisade, and into grass that stretched higher than my knees. I sprinted as if I were racing a cheetah, but Ay’s cursing guards were closing behind me. My calves and thighs flared like a bush fire under my skin. A slung stone grazed my hip, but it made me stumble a couple of steps.

Ahead grazed a herd of wildebeest. I ran straight through them, and they scattered in all directions. I hoped their stampede would run over my pursuers, or at least that they would lose us among the panicking animals. I did not hear any men scream death cries, but neither did I see them behind me anymore. It was better than nothing.

I had burned away so much of my energy that evening that I slowed into a panting stagger upon entering the forest. I put Nebet down and collapsed into the low crotch of a sycamore fig tree, letting out a relieved exhale. The darkness under the treetops would be our sanctuary this night, because I had worn myself out for the day.

“Cower all you want in those woods, traitor!” Ay’s croaky voice, muffled as it was by the foliage, was unmistakable. “The leopards shall do our work instead!”

Nebet buried her head in my bosom like a baby nursing her own mother’s milk. Her teary eyes and cheeks reflected even the little waning sunlight that shafted through the canopy. “We’re never going back, are we, Aunt Takhi?”

I stroked her disheveled puffs of hair and gave her my most motherly smile, because I could not give her anything else. Not even a lie. “Only the gods know what lies ahead, my sweetheart.”

“But they failed us. Sekhmet failed us, they all failed us! That old guy was right, they are dead!”

“But his never existed. Why else would we be able to get away from him? We even killed at least one of his minions!” I wrapped my arms around my niece. “Besides, our prayer got interrupted. What if we were to finish it? This time, we’ll pray on behalf of all Egypt against Akhenaten’s oppression!”

“But we don’t have my drum. Or her idol!”

She was right, we could not go home to our hut’s sanctuary. And Akhenaten had robbed all the temples in Egypt of the gods’ likenesses in favor of that Aten monstrosity. Or rather, all the temples still in use. Egypt’s history, with all its chieftains and kings with their various works, ran many centuries further in the past than those. Many of those past works lay buried under wilderness like the forest around us.

“We may not need them,” I said. “I can think of something even better. And it shouldn’t be far from here at all.”

##

The white gaze of the moon, surrounded by innumerable stars, had replaced the sun in a blackened sky. Its light, faint as it was, guided me and Nebet through the maze of sycamore and palm trees. She tightened her grip on my breast with every bird squawk, monkey hoot, or coughing roar of the leopard. I myself felt cold serpents of fear slither up my spine despite the balmy humidity.

A twig cracked. Nebet yelped, and I spun around with hands clenched onto my spear. Across a nearby clearing bolted the shadow of a small antelope. Wait, once we had found what we were looking for, I might need that. With a singular throw, I managed to spear that duiker through the head.

“Is that for us?” Nebet asked.

“It’s for Sekhmet,” I said while hauling the carcass onto my shoulder. “Keeping hanging on there, little one. We’re almost there.”

From the corner of my eye I spied paw-prints bigger than most leopard tracks on the leaf-littered ground---tracks almost as big as a lion’s in fact. But lions were creatures of the open plain, not the forest, and Nebet had been scared enough times as it was.

We passed a vine-entangled falcon sculpture with a disc and a cobra mounted on its head. This was the likeness of Ra, the god of the sun which Akhenaten’s devil Aten tried to usurp along with all the other gods. Behind it a stout limestone obelisk towered up into the treetop canopy from a high slanted platform. Between them and the statue of Ra rose overgrown walls with a gatehouse bisecting them.

“This is a Temple of the Sun, like those built during the Fifth Dynasty,” I whispered to Nebet. “That would make it, what, over a thousand years old?”

“Whoah, that’s even older than Grandmother!” Nebet said. We chuckled together.

“It’s older than any of our grandparents, little baboon. Now these were built in honor of Ra, and was Sekhmet not born from Ra’s eye? We might speak to her through him!”

We pried open the temple entrance’s door and entered an open courtyard blanketed with undergrowth. The giant obelisk reared on its platform at the court’s opposite edge, with another likeness of Ra chiseled into its based. This time Ra was not all falcon but instead a man with a falcon mask who tread the python Apep underfoot. He did not watch his temple alone, but shared it with other animal-masked gods standing along the courtyard’s sides. I recognized Anpu the jackal, Sobek the crocodile, Hetheru the cow, Khnum the buffalo, Sutekh the aardvark, and Djehuti the ibis.

And then there was Sekhmet, she of the lion mask.

Her representation was over thrice the height of the one back in our hut. Not even centuries of erosion, or the creepers wrapped around her, could hide the glint of her ivory fangs or inlaid amber eyes. Under the moon, her glare blazed with more predatory brilliance than I had ever seen on her images.

“Look here!” Nebet had run over to a niche underneath the surrounding wall and was tapping on something wooden. “Drums!”

And she was right. Drums of all sizes had been cached in there, some as small as her own miniature one and others big enough for a grown woman like myself. My niece and I could drum together now!

I laid my duiker kill at Sekhmet’s feet and lit it with a makeshift torch. It blossomed into a huge ball of flame that made my previous offerings look miserly for the comparison. And with both Nebet and I holding drums between our legs, we recited our prayer with the full force of our voices.

All our ancestors must have been among the chorus that chanted with us, but the gods around us sang loudest of all. The beats came in many rhythms from both our drums, from my heartbeat, and from my memories. Entire armies thundered beside us, hooting and roaring, women shrieking and whooping like hyenas on the warpath. And as our larger offering crackled under the fire, so too did whole hordes of our enemies have their bones cracked and shields split asunder.

Again, it was building up from my lungs into my throat. I was ready to let it out like I never could at home.

What came was a roar. But not from myself, or Nebet. It wasn’t even Sekhmet’s roar, but that of a real, mortal feline.

There were three of them that had bounded into the temple’s courtyard. They were big and heavily built as lions, but had the hides of leopards, with two having spots and one a pure black coat. The larger of the spotted ones had a short mane like a young male lion’s. I had heard stories of rare crosses between lions and leopards, but had never seen one in all my hunts. Never mind a pride of three!

Blocking the way between Nebet and these half-bred cats, I jabbed my spear at them with a hiss and snarl. The male of the trio bared his fangs and answered with a deep, coughing roar that froze my flesh to the bone. At his sides his mates crouched, rolling their shoulders with glowing green leopards’ eyes on my niece.

We were outnumbered, but even I could not outrun half-lion, half-leopard felines in the woods at night. All I could do was teach them the fear of humanity. So I chose to charge them head-on.

The male cat met my challenge with the lightning quickness of his leopard parentage and the lion’s brute might. He had me pinned back-first under his paws, the weight of his muscles nearly crushing mine. He would have split my bones had I not gotten one stab of the spear into his flank. It did not fell him, but in his roar of pain he relaxed his pressure enough for me to roll free.

I jumped to make another thrust, aimed at his skull. Again his mixture of lion’s strength and leopard’s reflexes defeated my attack with a swat of his paw that took off the spear’s bronze head. The sudden force of his blow threw me off my footing into one of the statues’ bases.

Nebet’s scream of terror and pain pierced into my heart as well as my eardrums. The spotted female cat had already caught her by the skirt in her fangs! I threw my decapitated spear into the beast’s shoulder, saving my niece from the crunch of death, but the male of the pride had sprung for me. I darted out of his way, letting him collide with the statue behind me, and put Nebet onto my back. I beat away the spotted female half-breed’s next attack with the duiker’s charred corpse and hurried for the temple entrance.

From the head of another idol, the cat with the pure black coat shot down paw-first in my way and slashed its claws across my breast. I reeled back until all three of the pride were circling us like vultures over a kill. I had been a fool. There was no way to beat these cats in battle. The best we could do was break out of their trap and shut them in.

After one kick into the male half-breed’s face, I rushed past him through the entrance’s doorway. Together with Nebet, we slammed the old door closed. Though it throttled back and forth with the felines roaring behind it, the hard wood it had been hewn from withstood their attacks with resilience belying its antiquity.

I scooped my whimpering niece up and mumbled thankful prayers that the night’s violence had not inflicted fatal damage on her. “It’s all right, my sweetheart. We’re safe now.”

“Not any longer, O Takhaet!”

Ay and his squadron of soldiers had found us after all! Ringed by all their spears and axes, I had spent too much energy to defy them any longer.

“This time, I’ll make it simple. Surrender your dead faith or die!” Ay’s sneer had widened to an open grin of malevolent joy. “Choose rightly, and we’ll bring you home and act as if this never happened!”

It would have meant defeat for my cause, for the traditions I and all the people of Egypt had followed before Akhenaten’s ascent. But Sekhmet and her brethren had failed us twice. No, if those three half-lions were any sign, she must have turned on us, never mind all that we’d done for her. And as long as my niece’s life was no longer at stake, it no longer mattered whether we swore by Aten rather than the gods who had deserted us.

“How about this, old man?” It was Nebet who spoke. Not even the tears in her eyes could extinguish away the determination in them. “You tried to kill us, so why don’t we do the same to you?”

She tugged the handle on the door. I helped her, and we ran straight through the confused soldiers the moment it banged open again.

The clamor of feline roaring, splintering spears and shields, and the screams and death cries of men echoed between the trees. So did our laughter together.

“You are a clever little baboon, aren’t you? How’d you hatch that one so quick?”

“They came when we prayed to Sekhmet. She must’ve summoned them for something. And besides, you used wildebeest on those men earlier.” Nebet was beaming with the fierce pride of a triumphant warrior, a beam I had shown myself many times in my career. Like aunt, like niece.

“All right, you win!” A gagging Ay, with wig fallen off and a blood-sprayed leopard-skin mantle, had tripped off his cane behind us. “I’ll tell Pharaoh you surrendered, and have your whole village left alone. Truth be told, that bloated fool would rather laze around in his new ‘palace’ than run his kingdom as he should. Sole representative of Aten’s will, my smelly wrinkled ass!”

After helping him up, my niece and I nearly exploded from the hilarious irony of it all.

##

When we returned to our village after daybreak, the people welcomed us with cheers, hoots, and songs of praise. The headman thanked us for driving back the tyranny of Akhenaten and his false god, promising to reward us with the greatest feast the village had ever known.

And so it was held that evening. Hundreds of drums cracked and rumbled as we roasted whole cattle and antelopes in Sekhmet’s honor, firelight dancing to the many rhythms. Hundreds of men, women, and children sang her praises, adding to the drumbeats with clapping, stamping feet, and the banging of spear butts and walking sticks. This time, I did not need memories or imagination to enhance the music. It was real, it pulsed all around me, and it even made me dance beside the flames.

Finally I could let it flow from my lungs, up my throat, and out of my mouth. And for once, it was my own voice from whence came the battle roar of Sekhmet.

The current vitriol broadcast globally during the political season is enough to cause concern and lose hope. The past is set, yet in many cases its impact on current events ignored to our detriment. The future is malleable and in flux, yet the tools we use to discern it and prepare for it - science - some in our society would have us fear to our peril. As a Trekkie, I lament that the future we used to dream of in 1968 has led to our current morass of flirting with a new form of self-government more like play dough anarchy: "Idiocracy" as I've seen oft-quoted in social media was meant to be a comedy, not a documentary. We have elements of our society "rooting for Armageddon" without a discernible or rational "plan B."

My hope in 2017 when Star Trek returns to CBS, we can recapture that awe, wonder and hope catapulting ourselves from superstition and authoritarianism beyond the ignorant darkness into the light only science in its proper context can give.
