The Physics Of Space Battles

Joseph Shoer is a Ph.D. candidate in aerospace engineering, studying how modular spacecraft could be assembled, and hoping that they will be the telescopes and human exploration vehicles of the future, and not for crushing the dreams of Martian colonists.

From Gizmodo:

I had a discussion recently with friends about the various depictions of space combat in science fiction movies, TV shows, and books. We have the fighter-plane engagements of Star Wars, the subdued, two-dimensional naval combat in Star Trek, the Newtonian planes of Battlestar Galactica, the staggeringly furious energy exchanges of the combat wasps in Peter Hamilton's books, and the use of antimatter rocket engines themselves as weapons in other sci-fi. But suppose we get out there, go terraform Mars, and the Martian colonists actually revolt. Or suppose we encounter hostile aliens. How would space combat actually go?

Beware Humans Bearing Gifts -- A Commentary

Christmas can be an anxiety-inducing experience for many (Image: Gareth Cattermole/Getty)

From New Scientist:

THERE'S a Latin proverb, per angusta ad augusta, which translates as "through trial to triumph". Literally speaking, "angusta" refers to a narrow passageway. It gives us the English word "anxious", signalling a place that presses against you, where the walls are tight, and you might be too big to get through. Anxiety is the feeling that you might not make it out the other side.

Autism Numbers Are Rising. The Question is Why? Read more

Sven Hagolani / Corbis

From Time Magazine:

One in 110 American children are considered to fall somewhere along the autism spectrum, according to the latest report released by the federal government. The new figure, which was released initially in October, comes from the most comprehensive set of data yet on the developmental health of eight-year-olds.

Increasing the previous federal estimate of 1 in 150, the new data suggest that 1% of children now exhibit some symptoms of an autism spectrum disorder (ASD), a collection of neurological conditions whose symptoms may range from mild social impairment to more serious communication, language and cognitive deficits. The estimate also represents a stunning 57% increase in prevalence since 2002, when health officials first began a nationwide effort to quantify the risk of autism in childhood.

About Wikipedia’s Handling Of Controversial Topics…Like Climate Science

From Fabius Maximus:

Summary: This is a hat trick. About effective propaganda. And climate science. And more evidence that Wikipedia cannot be relied upon as an information source regarding controversial matters — or any work of importance. (It’s always useful as a first place to look and source of links.)

Contents

1. “Wikipedia Is A Stunning Example Of How The Propaganda Machine Works“, Lawrence Solomon, National Review (reposted by CBS), 8 July 2008
2. “Wikipedia’s climate doctor“, Lawrence Solomon, National Post, 19 December 2009 – “How Wikipedia’s green doctor rewrote 5,428 climate articles.”

Update: an email reply by Wikipedia Editor Pierre Grés to Dennis Kuzara’s complaint about bias of Wikipedia Administrator William Connolley, posted at Watts Up With That, 19 December 2009 (see the actual Wikipedia file on this here):

“In September 2009, the Wikipedia Arbitration Committee revoked Mr. Connolley’s administrator status after finding that he misused his administrative privileges while involved in a dispute unrelated to climate warming.”

We’ll learn much about Wikipedia’s honesty by what happens now to the dozens of articles seriously distorted or outright suppressed by Connolley. Is this a structural problem with Wikipedia, or just a bad apple in the barrel?

Science Daily (Dec. 19, 2009) — Why does a human baby need a full year before it can start walking, while a newborn foal gets up on its legs almost directly after birth? Scientist have assumed that human motor development is unique because our brain is unusually complex and because it is particularly challenging to walk on two legs. But now a research group at Lund University in Sweden has shown that human babies in fact start walking at the same stage in brain development as most other walking mammals, from small rodents to elephants.

Cooking Is What Made Us Human

From New Scientist:

What was the central mystery of human evolution that you were trying to solve?

I was sitting next to the fire in my living room and I started asking the question, when did our ancestors last live without fire? Out of this came a paradox: it seemed to me that no human with our body form could have lived without it.

Why can't a human exist on the same diet as a chimpanzee?

A chimpanzee's diet is like eating crab apples and rose hips. Just go into the woods and find some fruits, and see if you can come back with a full stomach. The answer is you can't. The big difficulty is that the nutrient density is not very high. This is problematic for humans because we have a very small gut, about 60 per cent of the volume it would be if we were one of the other great apes. We don't have enough intestine to keep low-quality food in our gut long enough to digest it.

Avatar's Moon Pandora Could Be Real, Planet-Hunters Say

This artist's conception shows a hypothetical gas giant planet with an Earth-like moon similar to the moon Pandora in the movie Avatar. New research shows that, if we find such an "exomoon" in the habitable zone of a nearby star, the James Webb Space Telescope will be able to study its atmosphere and detect key gases like carbon dioxide, oxygen, and water. The key is to find a planet that transits its star, and then find a moon orbiting that planet more than one stellar radius away, so that the moon can be studied independently of the planet. Moreover, an alien moon orbiting the gas giant planet of a red dwarf star may be more likely to be habitable than tidally locked Earth-sized planets or super-Earths. (Credit: David A. Aguilar, CfA)

From Science Daily:

Science Daily (Dec. 18, 2009) — In the new blockbuster Avatar, humans visit the habitable -- and inhabited -- alien moon called Pandora. Life-bearing moons like Pandora or the Star Wars forest moon of Endor are a staple of science fiction. With NASA's Kepler mission showing the potential to detect Earth-sized objects, habitable moons may soon become science fact.

How High Will The Seas Go In A Warmer World?

Remi Benali / Corbis

From Time Magazine:

Even as negotiators scramble to salvage an agreement at the foundering Copenhagen climate talks, a new study in this week's issue of Nature shows that the consequences of inaction on reducing emissions could be more severe than anyone thought.

By looking back about 125,000 years, to a time when global temperatures were as high as they are expected to be by 2100, a team of scientists from Princeton and Harvard universities has calculated that the oceans were probably at least 26 ft. higher than they are now, maybe as much as 31 ft. higher. That's significantly higher than the 13-ft.-to-19-ft. range scientists have been counting on, and it is, write Peter Huybers of Harvard and Peter Clark of Oregon State University in an accompanying commentary in Nature, "a disconcerting message."
