Even babies understand the difference between ON and OFF. After mastering peek-a-boo, turning a switch on and off is one of a toddler’s favorite games. What will happen if I press here? Where did that light come from? Who made that noise? Something nearly always happens when a button is pushed, and it leaves children wanting to know more. At least that’s how it went in my house. My son wasn’t satisfied squeezing Tickle Me Elmo’s belly to hear the little guy giggle. He soon figured out how to switch Elmo on-off-on-off so rapidly that the poor fuzzball appeared to have a bad case of the hiccups.

How many people have been struck by meteorites falling from the sky? The fact of the matter is that we all have been…repeatedly! While injuries from fallen meteorites of significant size are extremely rare, falling all around us and onto us each day are the meteorites smallest siblings, micrometeorites.

When you hold a cup of juice while walking, the juice tends to spill because the cup accelerates forward (ax, FIG.1, green arrow) and backward (-ax) with each step. The juice tips in response to that acceleration, and may spill over the rim of the cup.
The Spill Not automatically tips the cup so that its top stays parallel to the juice surface (FIG.2). For example, if the juice surface tips to 30 deg, but the cup stays horizontal, the juice could spill. But if the cup also tips to 30 deg, we get no spill! Note that there are only 2 forces on each portion m of juice…the weight mg down, and the buoyancy force Fb of the juice pushing at a right angle to the surface. These two forces result in a horizontal accelerating force ma (in red). We see from FIG.1 that
