Challenge accepted. It has been a few years since I had the class, but my psychology class used Psychology, 7th edition by David G. Myers. Chapter 4, The Developing Person, studies the psychology of humans as they go through life, and it includes a section on adolescence. As the AC who also replied to my post pointed out, 2-4 years earlier onset is conservative, but since I didn't have anything handy at 2 in the morning, I estimated. And the idea that people didn't live past their 20's is preposterous, as has been pointed out many other times in this thread.
However, puberty now occurs significantly earlier than in the past. I don't have a source handy, but I believe puberty occurs 2-4 years earlier than it did in centuries past, so while yes people had children soon after reaching puberty, they were older (17-19), but still younger than today's accepted child-birthing ages.
The problem is that some people are terrified of nuclear power and do everything possible to stop it. I personally don't understand this irrational fear, since I grew up near the Savannah River Site, and most people in my community were comfortable with nuclear, but that has come from a long term relationship with the site, which is different from the rest of the US, which only remembers Chernobyl and Three Mile Island (even though Three Mile was a success). So, despite its benefits, nuclear will not be used as it could/should.

It's 12 nautical miles to international waters, but the economic zone extends for 200 nmi.
Well, he got you to waste your time, and I guess mine, too. Mission accomplished.
IIRC the atmosphere of mars is mostly CO2 already, which makes actually growing plants to be almost trivial.
Except that plants respire, which requires oxygen. CO2 is used to make food.

I've never seen a mouse with blue teeth either fly or crash a plane.

A pound is a unit of force, as you said. However, a unit of mass is a lb mass, which equals 1/32.2 slug.
(Consistent metric units are so much nicer.)
Being a radical abstinence-only no-sex-before marriage priest does not mean that person disagrees with abortion. It makes it likely, but not definite.
AP Physics has two levels: B and C. B is algebra based and C is calculus based, so if this book is algebra based (I haven't RTFA), then it is for B.

I now have something to do during CS class tomorrow!
