Post Carbon Society...

 


Being one that grew up during an era of segregation, "the American Dream" I managed to achieve via education and working in an industry that education prepared me quite well for.

 
In an era of "sound-bite politics"; short-sighted goals more concerned with "team victory" than with governing, this documentary should be a part of the debate on education, energy, science and ultimately jobs in this country.

 
As we see the price of gasoline rise at the pump: the price of bringing food to suburbia also rises, as fuel prices rise for the grocers to ship food to their shelves - they transfer that cost to us, a de facto tax irrespective of political party.

 
My fondest childhood memories: my father's "victory garden" he loved to work in our backyard. Literally every vegetable we consumed was grown out back, we then purchased our meats at the grocery store. It saved us much money. Today, it would allow consumers to buy more range-fed poultry and cattle products, healthy as well as a kind of Noble savage protest. In the aftermath of 9-11 and Hurricane Katrina, we're no longer looking for the Cavalry.

 
We may in the end, all need victory gardens...

More Land, More Moolah...

Keep Bandera Beautiful

If you think saving endangered species is expensive now, just wait a few decades. Climate change will require protected areas to expand if species are to be saved, potentially doubling the cost of such conservation efforts.

 

Rebecca Shaw of the Environmental Defense Fund in San Francisco, California and colleagues studied the Nature Conservancy's Mount Hamilton project, which spans 3200 km2of California. They focused on 11 species in the area with known climate tolerances.

 

They then combined the results of 16 climate models to estimate how the local climate within the project will change between now and 2100. That allowed them to determine how each species' habitat would move, grow or shrink – and thus how much more land would need to be acquired and maintained to preserve them.

 

The analysis suggests that the project will need an extra 2560 km2 of land by 2050. The figure had risen to 3800 km2 by 2100. Shaw estimates the extra cost at $1.73 billion by 2050, and $2.54 billion by 2100. That is slightly more than double the cost of maintaining the project in the absence of climate change.

Alien Sunrise...

Credit: New Scientist

Object: the star HIP 56948

Size: same as the sun

Temperature: same as the sun

Composition: same as the sun

Planets: same as the sun?
 

In the search for other Earths, the main goal is to find a planet the same size as ours that sits in the habitable zone – the region around a given star where planetary surface temperature would be similar to ours, allowing liquid water to exist.


But while an Earth-sized world in one of these habitable zones might have seas and rivers, it would look quite different bathed in blue-white or red light. That could affect the development of life. To exploit the available light, plant leaves could be yellow, orange or red, according to research in 2007 by the Virtual Planetary Laboratory at the California Institute of Technology.

 


Two observations:

  • 200 light years away: this will require breakthrough propulsion physics (blogged on last year), else such a trip is definitely "one-way" only.
  • Hm...that means "eat your spinach" could be even dicier if it's yellow! Just saying...Smiley

Silly Science Predictions...


"Silly science" Cartoon by NilbogLAND

I used this as an intro to "Why not S.T.E.M. (science, technology, engineering, mathematics)?" at Bethel Missionary Baptist Church to 31 students last Saturday. Kids put together their own original circuits & demonstrated to the group. BTW: the young ladies ROCKED. Two girls - 7 and 9 - needed a sliding or push button switch for their "flying saucer." When they couldn't find one in the kits provided, they designed and made their own!

The video "Silly Science" was created in 1960 (Cold War days), and I recall seeing it on Saturday morning shows. Some "predictions" of this 52-year-old cartoon:

Remote Control Box: Universal Remote Control

Robot Dishwasher: Automatic Dishwasher

Robot Vacuum Cleaner: Roomba

Talk-o-Vision: Video Conferencing / Skype

Glass Bottom Boats: See-Through Boats

Remote Control and Radioactivity: Remote Control for Nuclear Power

Instant Highways: Interstate Highway System

Aerial Refueling… (Not of cars!)

Rental Cars… (Not inflatable!)

Drive-Along Movies (now car DVDs)

Auto Parks... Mega Theme Parks

Toll Roads… (Sigh!)

Humans Riding Dinosaurs…ahem, not really!

Physics of Cancer...

Credit: AIP-Lead-in Photo

The American Institute of Physics publishes several articles on "The Physics of Cancer," and related articles illuminating the research in the topic towards a cure for the disease.

I offer this with some sensitivity and personal experience: my father ultimately expired from lung cancer in 1999; my mother was a breast cancer survivor until her passing in 2009.

It is comforting to know that biological, physical and mathematical sciences, and the yeoman's work of researchers are concentrated on this issue: the extension of human life in length and quality the ultimate goal.

For us as a nation to have a contribution and a stake in this, we need to encourage our youth to enter these fields, engage them in the classroom with exciting labs and non-threatening presentations; as contributors to the advancement of knowledge, not just the end-user-consumers. There should be a way to present science, technology, engineering and mathematics with a little less militancy (as in my own case); entertaining without theater or pedagogic sophistry.

For those, as I, who've been affected similarly, trust that there will be a dawn where like polio, this will ultimately be a part of our history.

Science...and hope.

We've arranged a global civilization in which the most crucial elements — transportation, communications, and all other industries; agriculture, medicine, education, entertainment, protecting the environment; and even the key democratic institution of voting — profoundly depend on science and technology. "We have also arranged things so that almost no one understands science and technology." This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.

Minivan Meteorite...



The picture taken in Reno, Nevada, on Sunday morning shows a meteor the size of a minivan plunging through the Earth's atmosphere, according to Bill Cooke of the Meteoroid Environments Office at NASA's Marshall Space Flight Center in Huntsville, Alabama.



Of course, this would have been one heavy minivan. Cooke said it weighed about 154,300 pounds. Your minivan probably weighs in at about 4,000 pounds.

Be Cool...

...minus Chili Palmer!

LASplashdotcom

Replacing roofs and pavements with more reflective versions could lower global temperatures by up to 0.07 °C, equivalent to a reduction in carbon-dioxide emissions of about 150 billion tonnes. That is according to researchers in Canada who used a global climate model to look at the effects of such albedo changes in urban areas.

I almost don't want to post the next paragraph:

"Scientists have been proposing novel ideas – mostly untested – for the geoengineering of global climate," says Hashem Akbari of Concordia University. "But humans have had experience with white buildings and reflective pavements for thousands of years without any unknown negative side effects. Hence, cool urban surfaces should be our geoengineering 101."

The problem isn't geoengineering...it's political will.

Dirac Cones...

Dirac Cones - PhysicsWorld

Physicists in the US have done calculations that suggest "Dirac cones" exist in thin films made of bismuth and antinomy. Dirac cones are features in the electronic band structure of a 2D material where the conduction and valence bands meet in a single point at the Fermi level...According to Tang, the films could also form the base material for next-generation electronic devices. "Electron speeds in devices made of bismuth–antimony would be hundreds of times greater than those in current silicon devices," he says.

Majorana Fermions-Sort Of...

In 1937, after the rise of quantum mechanics, Ettore Majorana, an Italian theoretical physicist, realized that the new physics implied the existence of a novel type of particles, now called Majorana fermions. After a 75-year hunt, researchers have now spotted the first solid evidence of their existence. And their discovery could hold the key to finally creating workable quantum computers .

 

Prior to Majorana's work, Austrian physicist Erwin Schrödinger came up with an equation that describes how quantum particles behave and interact. Paul Dirac, an English physicist, tweaked that equation to apply it to fermions, such as electrons, moving at near-light speed. That work tied together quantum mechanics and Einstein's special theory of relativity. It also implied the existence of antimatter, where every particle has an antimatter counterpart—such as electrons and positrons—and that the two would annihilate each other if they ever met. Dirac's work suggested that some particles, such as photons, could serve as their own antiparticles. But fermions weren't thought to be among them. It was Majorana's manipulations of Dirac's equations that suggested the possible existence of a new type of fermion that could serve as its own antiparticle.

Fun to Imagine...


I had a Ford coil--a spark coil from an automobile--and I had the spark terminals at the top of my switchboard. I would put a Raytheon RH tube, which had argon gas in it, across the terminals, and the spark would make a purple glow inside the vacuum--it was just great!

 

One day I was playing with the Ford coil, punching holes in paper with the sparks, and the paper caught on fire. Soon I couldn't hold it any more because it was burning near my fingers, so I dropped it in a metal wastebasket which had a lot of newspapers in it. Newspapers burn fast, you know, and the flame looked pretty big inside the room. I shut the door so my mother--who was playing bridge with some friends in the living room--wouldn't find out there was a fire in my room, took a magazine that was lying nearby, and put it over the wastebasket to smother the fire.

After the fire was out I took the magazine off, but now the room began to fill up with smoke. The wastebasket was still too hot to handle, so I got a pair of pliers, carried it across the room, and held it out the window for the smoke to blow out.

But because it was breezy outside, the wind lit the fire again, and now the magazine was out of reach. So I pulled the flaming wastebasket back in through the window to get the magazine, and I noticed there were curtains in the window--it was very dangerous!

Well, I got the magazine, put the fire out again, and this time kept the magazine with me while I shook the glowing coals out of the wastepaper basket onto the street, two or three floors below. Then I went out of my room, closed the door behind me, and said to my mother, "I'm going out to play," and the smoke went out slowly through the windows.

Last Flight of Noah's Ark...


The Last Flight Of Noah's Ark is a Disney film released by Buena Vista Distribution on June 25, 1980. The film stars Elliott Gould, Geneviève Bujold and Ricky Schroder. (Wiki)

A poignant note for yesterday's last flight of Discovery before retirement to the Smithsonian Institution. Noah's Ark; the Epic of Gilgamesh et al are essentially, stories of survival, using engineering principles to do so. I feel humans must become a space faring species, even if the only extraterrestrials we eventually encounter are our own grandchildren.
