Jerome Licini is a professor at Lehigh University. He and one of his students developed an apparatus to demonstrate why empty shampoo bottles tip over so easily. The reason: empty bottles have much less mass than full bottles, and their center of gravity is higher so they are basically begging to fall over at the slightest touch.
It's comforting to know that Professor Eric Laithwaite (1921-1997) former Professor of Heavy Electrical Engineering at Imperial College London and inventor of the maglev trains felt the same way as Insane Clown Posse about magnets. His opening remark in this 1975 video is "Permanent magnets are difficult things to understand. In fact, if we're absolutely… READ THE REST
I just learned about the "Center of the Universe" — a strange acoustic phenomenon in Tulsa, Oklahoma.

It's harder to breathe when you're congested, which is why many people either wake up frequently or feel as if they aren't fully rested. Eliminating those nasty allergens is an easy way… READ THE REST
