Setting us straight!

A lot of physics as taught in school and printed in textbooks is not just oversimplified but actually wrong. If you want your illusions shattered, read this page! Highlights include:

  • SCIENTISTS USE THE SCIENTIFIC METHOD? not quite.
  • LAKES AND OCEANS ARE BLUE BECAUSE THEY REFLECT THE BLUE SKY? No.
  • CLOUDS REMAIN ALOFT BECAUSE WATER DROPLETS ARE TINY? Wrong!
  • THE SKY IS BLUE BECAUSE OF COMPLICATED PHYSICS No, it's simple.
  • A LEMON-BATTERY CAN LIGHT A FLASHLIGHT BULB? doesn't work!
  • SOUND TRAVELS BETTER THROUGH SOLIDS & LIQUIDS? No it doesn't.
  • GRAVITY IN SPACE IS ZERO? It's actually strong.
  • A WING'S LIFTING FORCE IS CAUSED BY ITS SHAPE?, no, by trailing edge angle.
  • FOR EVERY ACTION, THERE IS AN EQUAL AND OPPOSITE REACTION? Newton said otherwise.
  • BEN FRANKLIN'S KITE WAS STRUCK BY LIGHTNING? He'd have died.

  • These and many other points are discussed and explained. Some take a while to get your head around, but it's worth the effort! Thanks to Niels for the link.
