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.

Jeff-

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.

Cheers
Jim

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.”

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.”
