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.
