Science Blogs

I’m somewhat of a science junky and this morning I just discovered a new repository of science related

ScienceBlogs is the web’s largest conversation about science. It features blogs from a wide array of scientific disciplines, with new voices coming on board regularly. It is a global, digital science salon.

The blog topics include everything from ethics to principles of uncertainty.

Mr. Angry and Mrs. Calm Switch Places

Here is a cool optical illusion where an angry man and a calm woman appear to switch places when you view them from far enough away. It’s something you have to see to believe. Apparently it also works when scaled in Photoshop or printed on paper.

GEN H-4 Personal Helicopter

Since it doesn’t look like the flying cars are on their way, what about personal helicopters? $31,000 will buy you the GEN H-4, a modern marvel that can go nearly 100 kph (aprox. 60 mph). See the GEN H-4 demonstration video. (2.6MB wmv)

Evolution Vs. Intelligent Design Redux

I discovered another pummelling essay destroying Intelligent Design. This one is good because it not only lays out the “evolution” of the Intelligent Design camp, but also explains the science behind evolution in a way that any astute reader would be able to understand.

It’s nice and thorough with about six long but fascinating pages – so set aside some time if you’re going to read it.

Evolution Vs. Intelligent Design

The Washington Post on the proof behind evolution and the Evolution / Intelligent Design (ID) case in Harriburg, Pa.

“When scientists announced they had determined the exact order of all 3 billion bits of genetic code that go into making a chimpanzee, it was no surprise that the sequence was more than 96 percent identical to the human genome.”

The chimpanzee genetic information let scientists put the very theory of evolution to some tough new tests and the predictions made under the theory passed.

Today a Federal judge in Harrisburg, Pa. USA, will begin to hear a case that asks whether Intelligent Design or other non-scientific explanations should be compulsory teaching material in a biology class.

But the plaintiffs, who are parents opposed to teaching ID as science, will do more than merely argue that those alternatives are weaker than the theory of evolution.

They will make the case — plain to most scientists but poorly understood by many others — that these alternatives are not scientific theories at all.

Stairway to Heaven Subliminal Messages

Some time ago I received an email from a professor at York University. He asked if he could use part of my Stairway to Heaven backwards site / idea for a class. Here is the conclusion of his experiment.


I have now given my lecture on perception, and the Stairway to Heaven was a real hit. Before I played it backwards, (and after they had listened forwards a few times), I distributed sheets of paper with the “words”. Half the class got the Satan stuff, and the other half got my own words, which have nothing to do with Satan or religion. I realized at the outset that my words did not fit quite as well as the Satan ones, but some lines fit very well. The demo went perfectly – those who had the Satan words could “hear” the backwards lines very well, and those who got my words, could hear at least some of my lines well. Interestingly, those who “heard” my words had a very difficult time hearing the Satanic words later on when I played it again.

Thanks again so much for your [help]. It has really helped me make a very important point about the nature of perception and how we actually construct our percepts.

Aerogel Photos

Aerogel will be used on the STARDUST spacecraft to capture comet particles from Comet Wild 2. The pics are amazing. They look fake, but they come from the NASA web site.

To collect particles without damaging them, Stardust uses an extraordinary substance called aerogel. This is a silicon-based solid with a porous, sponge-like structure in which 99.8 percent of the volume is empty space. By comparison, aerogel is 1,000 times less dense than glass, which is another silicon-based solid. When a particle hits the aerogel, it buries itself in the material, creating a carrot-shaped track up to 200 times its own length. This slows it down and brings the sample to a relatively gradual stop. Since aerogel is mostly transparent – with a distinctive smoky blue cast – scientists will use these tracks to find the tiny particles.


NASA Altering the true colours Mars Photos Update

It turns out NASA is not Photoshopping pictures of mars, but that, “The answer is that the color chips on the sundial have different colors in the near-infrared range of Pancam filters.”


Evidence that NASA is altering the true colors of the pictures of Mars

Investigation shows (google cache) that there are several indications that the NASA is tampering with the colours of the Mars Photo’s and changing them from a mildly red but Earth-like environment into a dark red Sci-Fi looking environment.

These links are DEAD. I tried looking at for a copy but there is nothing.


Nano Techonology Update

I came across a story in Wired this evening about the World’s Best Preforming Microscope. “The SuperSTEM microscope at Daresbury Laboratory in Cheshire, England, is so sensitive that it requires a special building capable of protecting it from the vibrations caused by raindrops. Its resolution is so sharp that researchers can count atoms on its images.”
