A study showed infants and toddlers who slept fewer than 12 hours in a day were twice as likely to be overweight by the time they reached the age of 3 as those who slept longer


They needed a study to realize this? When babies aren't sleeping they are eating. Of course they will gain more weight if they don't sleep. That means they have more time to keep eating stuff.

In science, we test hypotheses. It seemed a no brainer to the ancient greeks that a heavier ball fell faster than a lighter ball. And I suppose if Galileo actually did the experiment and confirmed the knowledge of the greeks, people would say "duh". But he found something rather quite different.

Science teaches us to test even what obviously seems true.

Actually a heavier ball does fall faster under most conditions. Air resistance.

A denser ball falls faster, not a heavier one. If you take the terminal velocity equation

you'll notice that the mass is divided by the drag coefficient. So, when the mass increases and the area increases by the same ammount, the change in terminal velocity is nonexistent.(m is mass, g gravitational acceleration, Cd drag coefficient, p density of substance object is falling through, A area, and Vt terminal velocity.

The experiment which may have been done by Galileo used two balls of the same material but different sizes.

Hence the "most conditions." I was under posting time pressure. Generally a heavier ball will have a higher mass/surface area ratio. It's certainly possible to design counterexamples though.

Older kids that don't get enough sleep don't do as well in school and don't grow like they're supposed to. They're much crankier and uncooperative.
A problem in class.
I can always tell which kids get enough sleep and those that don't.

Do you have any information on how much sleep is considered enough, canuck? My husband is very lax about Little_Bird's sleep times, and I'm struggling to get co-operation on making him get to bed early, because he believes that kids will sleep when they need to. But I don't have any faith in this approach.

Better to let the child wake up when they like, if it's possible. Bedtimes may need enforcing. Our 4 year old daughter will usually sleep 10 hours.

I like the bit about teenagers being chronically sleep deprived. Poor Koreans are even worse off!
