Polar bears have black skin...

2009-01-23T11:59:00Z

The thick fur insulates the body of the polar bear against the extreme cold of its arctic environment but polar bears actually have transparent, hollow hair called guard hair. These clear colored air filled guard hair help transmit heat from the sunlight to their black skin as a solar heat collector. Their guard hair are waterproof, so they also help keep the bear warmer when it is in water. Reflection of the sunlight from the transparent hair makes polar bears appear white, in the same way as reflection of the sunlight makes snow and ice look white. The dense fur completely hides the black skin underneath, which absorbs the heat energy from sunlight; plenty of light still passes through the transparent hair.

Trains Entering a Station

2009-01-17T11:29:00Z

Have you ever been told not to cross the yellow line on the platform, specially when a train enters the station? Do you know the reason why the yellow line exists? If you stand too close to an incoming train, there is a possibility that you might get sucked in between the train and the platform. The reason is very simple. When a train comes into a station it displaces air around it and creates a temporary vacuum. Objects (including you) which are placed close to the incoming train tend to get sucked into the vacuum. So as a safety measure the railway authorities have drawn an yellow line on every platform. Greater the speed of the train higher is the possibility of such an event. So next time when you are at the station, watch out for the yellow line!
