Study suggests we still don’t understand how mirrors work

Mirror

Dr Marco Bertamini, from the University’s School of Psychology, conducted a number of experiments by covering a mirror on a wall and inviting participants to walk along a line parallel to the mirror. He asked them to guess the point at which they would be able to see their reflection. Results showed that people believe they can see themselves even before they are level with the near edge of the mirror.
Dr Bertamini said: “People tend not to understand that the location of the viewer matters in terms of what is visible in a mirror. A good example of this is what we call the Venus Effect, which relates to the many famous paintings of the goddess Venus, looking in a small mirror. “If you were to look at these paintings, you would assume that Venus is admiring her own face, because you see her face in the mirror. Your viewpoint, however, is rather different from hers; if you can see her in the mirror then she would see you in the mirror.”

This is quite interesting. I sometimes get confused when I’m using my webcam and it is in mirror mode. I understand how a mirror works, it is just I don’t think about it when I’m looking at myself in the mirror or on my webcam. I think this happens because as you go about your daily life you don’t see everything through a mirror, so you see things from a different perspective. Quite an interesting article.

Purple frog found in India

Purple Frog

A new species of frog has been discovered in India. The amphibian is plump, purple, and its ancestors probably lived among dinosaurs 175 million years ago, according to DNA analyses. Two scientists, S.D. Biju of India, and Franky Bossuyt of Belgium, found the frog in the Western Ghats Mountains of Southern India. The new species, named Nasikabatrachus sahyadrensis, belongs to an entirely new family of frogs.
The frog’s closest relatives live 1,800 miles away on the islands of Seychelles, near Madagascar. So how did the species travel from Africa to India?

Transatlantic Tunnel – London to New York

Transatlantic Tunnel

So you’re thinking of travelling from London to New York, and not by plane – just go by tunnel. It’s not as if this idea hasn’t been presented before, but this seems more thoughtout, with more information about how it will be powered, how it will work and what to do incase of accidents. It would be magnetically levitated and would use a vacuum to keep everything sealed. To me it still seems too far ahead. I wouldn’t want to travel in one of these, it seems to risky and dangerous. If you really want to check this out then do. It is presented nicely in a Flash movie.

NASA describes plans for the Moon and Mars

To the Moon and Mars

As the uselessness of the shuttle becomes more and more apparent, it’s good to see that there is actual progress being made of the human return to the moon and future expeditions to Mars. This is a preview of the report that will be released by NASA in the next few weeks.

I found this on Digg and thought that it was quite interesting.

NASA delays launch of Discovery

Crew are ready for take-off

NASA has delayed the launch of the Discovery space shuttle, bound for the Internation Space Station, because of a fault in the fuel tank sensor. This would have been the first mission since the Columbia disaster in 2003, when the shuttle and all the 7 crew members were lost. The crew were ready for take-off when the order was given to abort the mission. It is unknown yet when NASA will reschedule the flight.

Saturn’s volcanoes shoot ice, not lava

Mountain

NASA’s Cassini probe will pass just 175km from Enceladus, a 500km-wide chunk of rock and ice with surface temperatures that hover around -180C.
I think this is very interesting and cool.
