Climate Action Reserve: Environmental Cartoons by Joel Pett


Topics: Climate Change, Global Warming, Greenhouse Gases, Politics


This post appears on President's Day. I started it last Wednesday. I say this to respect the family of Justice Antonin Scalia in their time of loss.

We have three co-equal branches of government: the Executive, the Legislative and the Judiciary. It is the "check-and-balance," purposely designed to be slow and plodding; arduous to not make changes quickly as would a despot subjecting a population to h/er will.

It is the judiciary - the Supreme Court - that blocked the Clean Power Plan.

"The Clean Power Plan is based on a strong legal and technical foundation, gives states the time and flexibility they need to develop tailored, cost-effective plans to reduce their emissions, and will deliver better air quality, improved public health, clean energy investment and jobs across the country, and major progress in our efforts to confront the risks posed by climate change," Earnest said. "We remain confident that we will prevail on the merits." *

As I said in Umbilical Cord, old money is inexorably addicted to making its wealth the way it wants to. Mayan pyramids aren't even safe. That means broadcasting counter propaganda that casts doubt (as they did for the cigarette industry); purchasing politicians both locally and nationally; influencing presidential elections because presidents appoint supreme court justices.

Clarence Thomas was appointed in 1991 by George Herbert Walker Bush, post the infamous Willie Horton adds in 1988. During his contentious confirmation hearings, accusations of sexual harassment came in sworn testimony by his former employee Anita Hill. His artful dodge and use of the term "high-tech lynching," made his enemies back off and cleared his confirmation to the Supreme Court. He's apparently been quiet as a church mouse ever since. His first major decision was finalized December 12, 2000, deciding the Florida "hanging chads" fiasco by a 5-4 vote:

- The same 5-4 vote that decided the Hobby Lobby decision;

- The same 5-4 vote that gutted the Voting Rights Act.

He has so far served six times the president that appointed him: 1991 - 2016 is 25 years, a generation. He may be silent, but he's darkly effective in forwarding a regressive, authoritarian agenda that will outlive him.

Do not fall in love with the person on the top of presidential tickets. I cannot get emotional about people I'll likely never meet. Don't get excited for the top ticket major elections and neglect the midterms. It is a failure to teach Civics that we have citizens so caught up in the hype of inflated campaigns that we forget we're not electing "kings": we're electing representatives of our will ["We The People"], not the moneyed few; the function and genius of a democratic republic.

However, what lives beyond any administration is who is appointed to the court and if fairly young, how LONG they serve.

A generation is an incredibly long time...to do lasting damage. The damage in this case can be the environment for generations the families of the justices are also subject to:

“Only when the last tree has been cut down, the last fish been caught, and the last stream poisoned, will we realize we cannot eat money.”

In 2001, I invented a method and device designed to discover gravity waves in local space/time and incorporated it in Discovery: Volume 1 of the Darkside Trilogy.

Though the exact method detailed in Discovery is a bit different than the LIGO Lab's hardware, the experimental method used to detect today's gravity waves is identical to that described in the novel.

Coincidentally, in May of 2001, a colleague of mine sent me a link to an article describing a similar "device" they were planning to deploy in Ireland, again employing the same method detailed in the Discovery manuscript.

This is not only vindication of the research used for Discovery, but for putting in the time and effort to make stories credible, seemingly real and to prevent readers from having to suspend belief because of faulty or lazy writing.

Queen mother Angela Bassett is a collective community favorite on the small and silver screens, playing some of our all-time favorite characters. Thanks to Bryan Fuller’s announcement as show runner for the new Star Trek television series reboot, the esteemed actress might be the franchise’s second black woman to playa Starfleet captain. Madge Sinclair was the first woman and black actor on screen as captain of the USS Saratoga. The show will be available on CBS All Access, the network’s online streaming service, in 2017.

Fuller is no stranger to the Star Trek universe. At the beginning of his TV career, one of his first gigs was writing episodes for Star Trek: Deep Space Nine. He then moved on to the Voyagerseries. A true fan of the show growing up, Fuller told EW, “My very first experience of Star Trek is my oldest brother turning off all the lights in the house and flying his model of a D7 Class Klingon Battle Cruiser through the darkened halls…It is without exaggeration a dream come true to be crafting a brand-new iteration of Star Trek with fellow franchise alum Alex Kurtzman and boldly going where no Star Trek series has gone before.”

Fuller, creator of Hannibal and Pushing Daisies, is a hire that the Trekkie community is excited about because of his passion for the show and it’s possibilities. Casting for Star Trek has not been announced, although he says Bassett would be his pick.

During an interview in 2013 he shared his idea of a dream cast for a Star Trekshow. “I want Angela Bassett to be the captain, that’s who I would love to have, you know Captain Angela Bassett and First Officer Rosario Dawson. I would love to do that version of the show but that’s in the future to be told.”

The blerd Trekkie community is crossing their fingers that Fuller hasn’t forgotten his dream now that he’s landed the position, starting the hashtag #CaptainAngelaBassett.

Time will only tell whether Bassett will be recording captain’s logs on her own starship in 2017. It never hurts to dream, and “fancasts” are making more of an impact than ever in the age of social media.

Ripple Effect...

Simulation of Gravitational Waves
NASA researchers simulated the gravitational waves that would be produced when two black holes merged.


Topics: Gravitational Waves, Einstein, General Relativity, Theoretical Physics


A century ago, Albert Einstein hypothesized the existence of gravitational waves, small ripples in space and time that dash across the universe at the speed of light.

But scientists have been able to find only indirect evidence of their existence. On Thursday, at a news conference called by the U.S. National Science Foundation, researchers may announce at long last direct observations of the elusive waves.

Such a discovery would represent a scientific landmark, opening the door to an entirely new way to observe the cosmos and unlock secrets about the early universe and mysterious objects like black holes and neutron stars.

Scientists from the California Institute of Technology, the Massachusetts Institute of Technology and the LIGO Scientific Collaboration are set to make what they bill as a "status report" on Thursday on the quest to detect gravitational waves. It is widely expected they will announce they have achieved their goal.

Before now, the strongest evidence of gravitational waves came indirectly from observations of superdense, spinning neutron stars called pulsars. In 1974 Joseph Taylor, Jr., and Russell Hulse discovered a pulsar circling a neutron star, and later observations showed that the pulsar’s orbit was shrinking. Scientists concluded that the pulsar must be losing energy in the form of gravitational waves—a discovery that won Taylor and Hulse the 1993 Nobel Prize in Physics. Ever since this clue, astronomers have been hoping to detect the waves themselves. “I've certainly been looking forward to this event for a long time,” Taylor says. “There is a long history, and I think projects that take this long to bear fruit require an awful lot of patience. It's about time.”

The discovery is not just proof of gravitational waves, but the strongest confirmation yet for the existence of black holes. “We think black holes exist out there. We have very strong evidence they do but we don’t have direct evidence,” Lehner says. “Everything is indirect. Given that black holes themselves cannot give any signal other than gravitational waves, this is the most direct way to prove that a black hole exists.”

Quantum Heat Transfer...

Physicists in Finland have shown that it is possible to conduct heat over macroscopic distances at close to the maximum efficiency permitted by quantum mechanics. By directing photons along a superconducting waveguide, the researchers transferred heat between two resistors spaced up to a metre apart – some 10,000 times further than previously possible at the quantum limit. They say their technique could someday be used to cool chips inside quantum computers.

Quantum mechanics tells us that heat flow, like electric current, can be quantized. If a wire is so thin that an electron's cross-sectional wavefunction can only assume one possible configuration as it travels along the wire, there is an upper limit to the rate at which electrical energy can be transmitted for any given voltage. Likewise, there is a maximum rate at which heat energy can be transferred along a single channel connecting a hot bath to a cold one when the baths are at given temperatures. This is the quantum of thermal conductance, which is reached when the hot bath emits energy perfectly, the cold bath absorbs perfectly, and there is no heat loss along the way.

I'm not saying we'll ever develop warp drive (though, we appear to be working on it). I'm reminded of Jules Verne: From Earth to the Moon. He posited a space gun, and did some rough calculations. He was way off, but think of when he wrote it, and fired the imaginations of scientists and engineers for four generations: 1865. We made it 103 years later on a rocket, though some still sadly doubt.

We've become too focused on our minor worlds of apps on phones, news feeds and million player online games; we've become consumers, not producers or dreamers. We nostalgically reach backwards to halcyon days that never existed except for personal myths, comforting though they may be.

Star Trek inspired a generation of scientists and engineers where some of the things we take for granted - automatic doors, cell phones, nanotechnology, remote control, robotics, WI-FI - were all inspired by a fictional story of going to strange new worlds and not being afraid of the different-than-us: but to boldly seek out challenges. We looked forward to the future; we weren't afraid of it, and we all...looked up.

Move over, James T. Kirk, "Star Trek" has another captain now. CBS Studios has tapped "Hannibal" creator Bryan Fuller — a veteran Trek writer — as a co-creator for its new Trek TV series launching in 2017.

Fuller has written for "Star Trek: Deep Space Nine" and "Star Trek: Voyager," and brings a deep appreciation of the "Star Trek" world to the new show, according to CBS Studios representatives. The new show will air on CBS All Access, a digital streaming platform. (The first episode will air on live TV.) [1]

*          *          *          *          *

“For the past 50 years, Star Trek has been a groundbreaking franchise that not only changed the landscape of television, but made a significant impact on pop culture,” said David Stapf, President, CBS Television Studios. “When we began discussions about the series returning to television, we immediately knew that Bryan Fuller would be the ideal person to work alongside Alex Kurtzman to create a fresh and authentic take on this classic and timeless series. Bryan is not only an extremely gifted writer, but a genuine fan of Star Trek. Having someone at the helm with his gravitas who also understands and appreciates the significance of the franchise and the worldwide fan base was essential to us.”

Fuller most recently served as executive producer and writer on NBC’s Hannibal, based on the characters from the book Red Dragon by Thomas Harris. He got his start writing Deep Space Nine, followed by Voyager, where he worked his way from freelance writer to staff writer to co-producer. Fuller went on to create the critically acclaimed series Dead Like Me and Wonderfalls. Also, he served as writer and co-executive producer on the first season of Heroes, before leaving to create the Emmy Award-winning Pushing Daisies. Fuller is currently executive producing along with partner Michael Green an adaptation of Neil Gaiman’s novel American Gods for the STARZ network. [2]

What becomes of America's nuclear waste?

Within the context of my science fiction/thriller, S.Y.P.H.E.N., I question the ever present issue of the United States' nuclear waste disposal system. Just what is the best tactic to take to get rid of and or store this country's dangerous spent nuclear fuel and highly radioactive waste from our power plants and war machine production? S.Y.P.H.E.N. doesn't lay out any definite plans, but it does raise questions: Was the proposed Yucca Mountain Nuclear Waste Repository in Nevada really a scientific bust as a site to store the waste/radioactive material underground? Were Washington politics to blame for the closure of the proposed facility? Nevada residents, environmentalists and a vehement Democratic Nevada Senator Harry Reid opposed on one side and other residents who touted the jobs and boost to the Nevada economy supported it on the other. Currently, the waste material is stored at the WIPP, or Waste Isolation Pilot Plant, in New Mexico where some mistakes made caused a leak in 2014 and brought into question not only the urgency to find a long-term solution to the problem, but even shines a light on just how safe WIPPs facilities are as well.

If this nation increases its reliance upon nuclear power, it will require additional disposal capability. The Yucca Mountain issue is a deep one that garners support on both sides. What's stated here only scratches the cliched surface. The bottom line, like the fight against terrorism, is that the issue isn't going away. It will increase its presence forcing this country to have to come to the conclusion that we can't continue to kick this challenge down the road for other generations and administrations to deal with it. Within the context ofS.Y.P.H.E.N., I hope to add fuel to the fire to stoke the powers that be into more concerted actions before we hit critical mass with the issue. I'll be posting various updates from around the country about this subject and will simply title them, The Waste Lands Report. To many, we've been there for some time now. It's past time to find a permanent solution(s) before we're all wearing Fallout 4 gear in a landscape akin to S.Y.P.H.E.N.s cover.

Hey fans, welcome to my new blog, Cops, Criminals, Commandoes and Creatures in Christ (Sometimes!) Blog. With this new blog, I’ll delve into some of the inner workings of what I do, what’s on the horizon pertaining to my next release, what’s going on in the publishing industry, maybe some movie and TV reviews, sports talk and discussion of life in general to keep the blog varied.

I’ll start this initial blog post with this question: What do you do when you start a new life, “forgetting those things which are behind and reaching forward to those things which are ahead…” (Philippians 3:13), and your past taunts you again?

That’s one of the provocative questions at the heart and soul of my  first Metro Black & Blue Books police procedural suspense novel, Kremlin TideKremlin Tide, tells the story of the elite Atlanta Police Department’s Homicide Squad known as,‘The X-Men’, who attempt to decipher if the series of crimes they’re investigating are the work of a psychotic serial killer and or a ruthless group of individuals with malicious intent on their darkened minds?

In the sequel, Cold Lick, the Atlanta X-Men Homicide Squad investigate the deaths of a pair of Atlanta Police officers. The crime sets off a series of interconnected events that reveals an underbelly of a criminal organization with a trail of guilt and innocence from suspects and allies alike that collide on every side. We're witnessing a great deal of suspect police investigation that in some cases lead to unexpected deaths across the country. American citizens need to respect the authority in their cities and the police need to abide by the laws that govern its citizenry and their enforcement obligations. Some government officials believe they can operate above the law with impunity and Cold Lick delves into some of that dynamic.
 
With these stories, I hope to add my name one day to the pantheon of other formidable and anointed writers penning tales from a biblical viewpoint in the mystery, suspense, thriller and speculative genres like authors Ted Dekker, Steven James, Brandilyn Collins, James Scott Bell, Dee Henderson and others. In addition, I’m hoping to add in African-American perspectives to the who-done-it, why-done-it or what done-it goings on too like Tyora Moody, Bonnie Calhoun, Brandon Massey, Tananarive Due, Eric Jerome Dickey, Rasheedah Prioleau, Walter Mosley, Steven Barnes, the late Octavia E. Butler and others.


Thanks to all for your support of Kremlin TideCold Lick and my latest release,S.Y.P.H.E.N. and be sure to tell your spheres of influence to give these books a shot and leave reviews on the various retailer and social media sites too. Thanks again and may you experience compelling reading until the next post.​

Occam's Razor...

It's looking less likely that a swarm of comets or an "alien megastructure" can explain a faraway star's strange dimming.

The star (nicknamed "Tabby's Star," after its discoverer, Tabetha Boyajian) made major headlines last October when Jason Wright, an astronomer at Pennsylvania State University, suggested that it could be surrounded by some type of alien megastructure. A more likely idea — one that's far less exciting — is that the star is orbited by a swarm of comets. But scientists can't be sure either way.

The first signs of the star's oddity came from NASA's planet-hunting Kepler space telescope, which continually monitored the star (as well as 100,000 others) between 2009 and 2013. Astronomers, citizen scientists and computers could then search for regular dips in a star's light — a sign that an exoplanet has passed in front of that star. The largest planets might block 1 percent of a star's light, but Tabby's star dropped by as much as 20 percent in brightness. That, in and of itself, would be weird. But the periodic dimmings didn't occur at regular time intervals, either — they were sporadic. The signature couldn't be caused by a planet, scientists said.

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

Reported by: Antonio Castelan
Published: 11/20/2015 6:49 pm
Updated: 11/20/2015 6:56 pm
 
LAS VEGAS (KSNV News3LV) -- The plan for storing U.S. nuclear waste just hit another roadblock. The state is telling the federal government Yucca Mountain isn't a safe site for those living nearby Amargosa Valley.

State nuclear regulators say 14-hundred people living in Amargosa Valley would be in danger if radioactive waste made its way to nearby Yucca Mountain. 

Bob Halstead with the State Agency for Nuclear Projects said, "It's not a question of whether radioactive contamination would come out of the repository. It's a matter of when it would come out. How much would come out? How far it would travel. How quickly it would travel the groundwater gradient through Amargosa. Valley."

Bob Halstead with the State Agency for Nuclear Projects helped draft the 53-page report. 

Halstead stresses groundwater contamination is one of the biggest concerns when it comes to Yucca Mountain being used as nuke dump site. 

Halstead said, "We were very disappointed that the nuclear regulatory commission having found that the Department of Energy had done a difficult job is assessing impacts failed to correct those deficiencies."

Not Fermi...



Topics: Fermi Paradox, Planetary Science, Space Exploration, SETI


Well, this is news! Tipler in particular kind of (ahem), went over the edge in the theory world, and thus everyone kind of treats him like your very strange uncle. He apparently plays in the story of the Fermi Paradox that wasn't...

If Fermi wasn't the source of this pessimistic idea, where did it come from?

The notion “... they are not here; therefore they do not exist” first appeared in print in 1975, when astronomer Michael Hart claimed that if smart aliens existed, they would inevitably colonize the Milky Way. If they existed anywhere, they would be here. Since they aren’t, Hart concluded that humans are probably the only intelligent life in our galaxy, so that looking for intelligent life elsewhere is “probably a waste of time and money.” His argument has been challenged on many grounds—maybe star travel is not feasible, or maybe nobody chooses to colonize the galaxy, or maybe we were visited long ago and the evidence is buried with the dinosaurs—but the idea has become entrenched in thinking about alien civilizations.

In 1980, the physicist Frank Tipler elaborated on Hart’s arguments by addressing one obvious question: where would anybody get the resources needed to colonize billions of stars? He suggested “a self-replicating universal constructor with intelligence comparable to the human level.” Just send one of these babies out to a neighboring star, tell it to build copies of itself using local materials, and send the copies on to other stars until the Galaxy is crawling with them. Tipler argued that absence of such gizmos on Earth proved that ours is the only intelligence anywhere in the entire Universe—not just the Milky Way galaxy—which seems like an awfully long leap from the absence of aliens on our one planet.

Hart and Tipler clearly deserve credit for the idea at the heart of the so-called Fermi paradox. Over the years, however, their idea has been confused with Fermi’s original question. The confusion evidently started in 1977 when the physicist David G. Stephenson used the phrase ‘Fermi paradox’ in a paper citing Hart’s idea as one possible answer to Fermi’s question. The Fermi paradox might be more accurately called the ‘Hart-Tipler argument against the existence of technological extraterrestrials’, which does not sound quite as authoritative as the old name, but seems fairer to everybody.

Sterile Neutrinos...

This is very interesting. Sterile neutrinos are dark matter candidates. From APS Physics, April 24, 2014:

A hypothetical neutrino that does not interact through the weak force could be the source of a recently detected x-ray emission line coming from galaxy clusters. However, previous models using this so-called “sterile” neutrino as a form of dark matter were not able to satisfy constraints from cosmological observations. Now, writing in Physical Review Letters, Kevork Abazajian of the University of California, Irvine, shows that a sterile neutrino with a mass of 77 kilo-electron-volts (keV) could be a viable dark matter candidate that both explains the new x-ray data and solves some long-standing problems in galaxy structure formation.

* * * * *

A new experiment to search for hypothetical particles known as sterile neutrinos has been given the green light by scientists at the CERN particle-physics laboratory near Geneva. The SFr 200m (£140m) Search for Hidden Particles experiment (SHiP) would be built at CERN and start up a decade from now. The lab's member states will, however, need to approve the project before construction.

Predicted by certain extensions of the Standard Model, sterile neutrinos – if they exist – would interact extremely weakly, if at all, with ordinary matter. However, sterile neutrinos would transform into and out of standard neutrinos, revealing themselves via a greater- or lesser-than-expected rate of oscillation between the different types, or "flavors", of neutrinos. Physicists working on the Liquid Scintillator Neutrino Detector (LSND) at the Los Alamos National Laboratory in New Mexico between 1993 and 1998 saw some evidence for such a transformation, but other experiments have failed to see a similar signal.

There are other plans to look for these hypothetical particles, but these experiments would focus on light sterile neutrinos with masses of less than one electronvolt. SHiP, in contrast, would seek more massive sterile neutrinos known as heavy neutral leptons. Weighing a few gigaelectronvolts, such particles would, very occasionally, decay into ordinary matter. According to SHiP spokesman Andrey Golutvin of CERN, their existence, unlike that of their lighter counterparts, could explain the predominance of matter over antimatter in the universe and the nature of dark matter. "Finding a light sterile neutrino would be a Nobel prize discovery, but it wouldn't solve the problems of the Standard Model," he claims.

Cam Musings...

Topics: Diversity, Diversity in Science, HBCU, Women in Science


I have in recent postings, avoided saying specific things about African American/Black History Month, Women's History Month; Hispanic Heritage Month not because I don't appreciate or celebrate them. It's partly due to sheer exhaustion: double posting (as I've done in the past) is kind of taxing. Most of what you see I decide on days or hours before it appears. Also, the workload in my (now) day job has increased exponentially.

I participate in a Facebook group called Quantum Physics. I post things thus related to Quantum Physics when it applies, and an administrator decides to post when s/he deems it fits their posting criteria.

I was quite surprised to have this exchange:


I immediately thought he meant the Copenhagen Interpretation by Niels Bohr and Werner Heisenberg (mentioned when I learned Quantum Mechanics from Dr. Tom Sandin at North Carolina A&T State University); I also thought of the famous Bohr-Einstein debates at the dawn of Quantum Mechanics that eventually led to the Copenhagen Interpretation.

However, I was taken aback by the statement: "There is no need for a rebuttal, it is just questioning why such an effort is made to disprove some minority who don't understand quantum mechanics."

Now, if the minority he's referring to is a numerical naivete with respect to the larger physics community, I'll give him a pass on his grammar; if he was referring to ME, "doesn't" sounds much better. The fact he stopped replying/trolling was revealing. Note that in my responses, I didn't really insult him. Recall that my post had to be approved, so his problems are essentially with the Facebook administrator, Physics Today and the researchers that published their findings.

I call this "Cam Musings," as my home state's team, the Carolina Panthers is in Super Bowl 50. I'm cheering not because Cam Newton and I are both African American, it's because I'd like to see the Panthers "bring the trophy home."

I have also read the vitriol and racism of others that feel he's not behaving with "dignity" when he celebrates a touchdown or a win. The obvious comparison is to Denver Broncos quarterback Peyton Manning - reserved for sure, but a convenient dodge to what the real issue is for some. I'm old enough to remember when there was a common notion African Americans were not "smart enough" to play as a quarterback until Doug Williams broke through that barrier.

Another hero of mine, Dr. Ronald E. McNair - also of NC A&T, died in the Challenger Disaster 30 years ago on 28 January 1986. He had to re-accomplish his research at MIT over three weeks of no sleep as someone sabotaged it. I know this because I spoke with him sadly, the month before his fatal mission.

If Dr. McNair had, Cam Newton or I spent too much time coddling the fantasies of racist trolls, we would not get much work done. I will cheer for Cam and the Panthers because I want my home team to win for no other reasons than being from North Carolina and having the best record in the league. For my appallingly xenophobic foil, I leave this quote from Nobel Laureate Richard Feynman (who investigated, and found faulty O-rings the cause of Challenger's loss) for him to meditate on:

"The difficulty really is psychological and exists in the perpetual torment that results from your saying to yourself, "But how can it be like that?" which is a reflection of uncontrolled but utterly vain desire to see it in terms of something familiar. I will not describe it in terms of an analogy with something familiar; I will simply describe it. There was a time when the newspapers said that only twelve men understood the theory of relativity. I do not believe there ever was such a time. There might have been a time when only one man did, because he was the only guy who caught on, before he wrote his paper. But after people read the paper a lot of people understood the theory of relativity in some way or other, certainly more than twelve. On the other hand, I think I can safely say that nobody understands quantum mechanics. So do not take the lecture too seriously, feeling that you really have to understand in terms of some model what I am going to describe, but just relax and enjoy it. I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possible avoid it, "But how can it be like that?" because you will get 'down the drain', into a blind alley from which nobody has escaped. Nobody knows how it can be like that."

4-D Printing...

Topics: 3D Objects, 3D Printing, Additive Manufacturing, Biology


If you are tired of the hype around 3-D printing, brace yourself, because it’s time to add another “D.” Yesterday, researchers unveiled a new process they can use to “4-D print” flat objects that change into complex shapes when they are immersed in water.

The new demonstration builds on the microscale printing process developed under the leadership of Jennifer Lewis, a materials scientist at Harvard. The images are captivating, but they aren’t just pretty pictures; they also hint at a fundamental new capability that could be applied in useful ways.

This is not the first time we’ve heard about 4-D printing, which refers to printing things that are “programmed” to change shapes later on. Three years ago Skylar Tibbits, a research scientist in MIT’s architecture department, introduced the term at the TED Conference. Tibbits’s process employed two materials, a rigid one and a softer one that expands when put in water.

TECHNOLOGY REVIEW: Physicists have worked out how to measure the magnetic fields generated by single nerves from outside the body and at room temperature.

Biologists have known that nerves produce and respond to electrical signals since the 18th century, when Luigi Galvani discovered that the muscles in a frog’s leg twitch when stimulated by a spark.

However, the systematic study of the electrical signals that nerves produce had to wait until the early 20th century for the development of sensitive electrical recording equipment such as the cathode ray oscilloscope.

This development revolutionized the understanding of nervous function. The ways nerves conduct signals can be a powerful indicator for diseases such as multiple sclerosis and can even detect certain types of intoxication.

And yet the method has some drawbacks. For example, measuring electrical signals in nerves by inserting a needle-like electrode is somewhat invasive, and the mere act of attaching an electrode to a nerve can change the signal, making the results hard to interpret. So neuroscientists have long hoped for a noninvasive technique that could do the job instead.

That may be about to happen thanks to the work of Kasper Jensen at the University of Copenhagen in Denmark and a few pals who have developed a way to easily measure the magnetic fields associated with electrical signals in nerves. The technique could pave the way for a new generation of diagnostic tools for spotting diseases linked to nervous function and for understanding the basic function of nerves.

What We Value...

I can say I've met a Nobel Laureate in Professor Weinberg, and potential ones in my life (one of his students in particular, he and his wife personal friends). I can state I haven't been disappointed in them as people, warm, approachable and knowledgeable about physics and life. I lament I am too young to not have lived when Einstein was alive.

Open carry became law in the state of Texas this month on January 1st; August 1st for the campuses. Some businesses have the ability to mitigate them as likely, their customers don't want to think about weapons next to their groceries or lattes...

Dr. Weinberg - in the brief time I met him at the NSBP/NSHP conference in Austin - probably doesn't do "too much fuss" well. He likely endures it, but would rather not.

There is not one scintilla of evidence that a "good guy with a gun" thwarts a bad guy. There's more data that flying lead tends to have an exponential multiplier effect, and that sometimes tragically with trained law enforcement personnel...and citizens.

So, this is a very bold stance, but an important one: what do we value as a culture? Is it knowledge, as in the competitive knowledge needed for 21st Century employment in a global economy, or macho John Wayne/G.I. Joe fantasies of shootouts with cap pistols/paint balls, and a cartoon (no death) reset?

Everyone in this country has the right to every single amendment of the Constitution. We tend to overlook this:

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. I'd think part of that happiness is coming home in the same shape you left in.

A professor: any level, anywhere - Nobel Laureate, Tenured, Assistant, Associate, Teacher K-12 - has to teach with a certain impunity to tell the student sometimes hard things, such as you didn't master the material. That's usually known as drop before the last date, or accept the less-than-"C" grades. No one wants to feel held hostage in their classrooms. Hormones and hurt feelings: what could POSSIBLY go wrong?

Hopefully, a flagship university values having a Nobel Prize winner as part of their science research faculty. If not, I'm sure any other campus will welcome him with open arms and demands met, or as he has alluded, he might retire. Other scientists, engineers and other fields might follow the example of his exodus.  It could possibly be a great loss to the university, to science; the epitome of a Pyrrhic Victory.

Entropy - the tendency of systems to go from order to chaos/disorder - is how we came to measure something called time and its changes; it claims us all eventually.

It just needn't be as sudden as our current national asylum.
