Answer by Awesome_Spectacular:

I have to say, this week's question was a little hard. We got several different opinions and answers from people. Just a little heads-up: please follow the rules! If you don't do things like write your own answer or provide a link, we can't give you credit for the answer. Sunnyd has clearly stated whoever didn't state a link this week will not get credit, so next for those of you, please make sure you have link next time!

Back to the question. Even though there were many opinions, the one I thought was correct after doing some research (with A LOT of help from Pippin14), the answer I think is correct is that drier air causes clouds to break up into smaller clouds. When drier air gets mixed with clouds, some parts of the cloud break away, or in more scientific terms, evaporate. Basically, this is the way a cloud breaks up into smaller clouds. When answering this, you should have remembered that clouds are little drops of frozen crystals, or water.

In a way, Pizzalover was technically correct in saying that clouds can't break up into smaller clouds because it depends on the size of the frozen droplets of water that make a cloud big or small. But technically, of that cloud, when dry air is mixed, parts of the cloud will evaporate, breaking it up into a smaller cloud.

Book Chat: Economics

I can honestly say that I'm shocked (and slightly embarrassed to admit) that two books about economics, of all things, would have changed my perspective of the world.  Honestly, you'd think some science book would do that, right?  But alas, in my age of ever-changing perspectives and general teenagehood, books on "the social science of decision- making" rather than "the study of the human brain" have changed the way I think.  Who would have known?

Anyway, all that being said and done, I should talk about the books, shouldn't I?  I'll go from oldest to most recent.  Here are the first two (they're related):

Freakonomics
"A rogue economist explores the hidden side of everything"
By Steven D. Levitt and Stephen J. Dubner


SuperFreakonomics

"Global Cooling, and Why Suicide Bombers Should Buy Life Insurance"

By Steven D. Levitt and Stephen J. Dubner

Simply put, Freakonomics and it's sequel has one basic concept in mind: incentives cause people to do things.  Or, to put in one word, it's about incentives.  It's an extremely popular book, and for good reason-it has wonderful examples, shows surprising (but logical) points to make, and talks about some controversial issues. Even kokopelli1015 has read excerpts, but hasn't read the entire thing.  I do talk about Freakonomics in this post, but I know few of you will read that post, so quick review- has some controversial issues about discrimination and abortion as a heads up, and talks a lot about crime, and obviously, the role of incentives in the crime.  It also talks about a lot of other things, so even if none of those seem appealing to you, there's a whole lot of hidden treasures in that book that's worth reading for.  SuperFreakonomics is the one I read recently, though.  Another heads up: there is inappropriate content in the first chapter, but it doesn't look at it in a you-know-what light, but in more of an analytical view- looking at data and whatnot.  Still, get it checked out by an adult if you want before you read it to be safe.  It's been a little while, but I do know that this book doesn't focus all that much on crime as Freakonomics, but talks about other subjects as well.  It's got a pretty extensive chapter on global warming and some (easy) ways to combat it.  My personal favorite chapter is the last one, on monkeys (that's where the question box came from! I forget what my family and I were talking about to get to monkey hair...).  Both books, though, are honestly quite amazing and will change the way you look at things.  Really.  It did that to a hard-core science fan, and I'm sure that most people will find it a wonderfully fascinating read.  There's even a really interesting blog for Freakonomics that I'd recommend to read as well.

Trade-Off
"Why Some Things Catch on and Others Don't"
By Kevin Maney

This book was amazing.  Really.  It's all about a simple concept that's behind which products catch on- and which don't.  This basic concept is fidelity (quality) vs. convenience.  A product will go off well in the market if it either has super high fidelity or super high convenience.  It is impossible to have both- and trying to make a product have both is chasing the "fidelity mirage," which sounds all too possible but is a fool's errand.  This, along with other spin-offs of the fidelity vs. convenience trade-off is more thoroughly explained in the book.  There are tons of real, vivid, examples of products that have failed- and succeeded wildly.  While some may not be as well-known to us, like the company Tesla Motors, others we are all too familiar with (e.g. the iPhone and some other well known companies).  I don't think that I'll ever look at anything the same after I read this- especially right after reading this, you keep thinking about whether it's high convenience, high fidelity, or a bit of both.  Ever wonder how the whole revamp of the question box rewards system sprang into being?  Well, this book was part of the answer.  Really, it's a great book, and I'd highly recommend you read it.

Admittedly, these three books aren't quite science related, but they're really great books that puts a spin on your perspectives of things.  Try them out and see what you think, and you may be surprised that non fiction books can be just as interesting as Twilight, in different ways.

I must say, this was a pretty difficult question to answer! For all those Question Box Answerer's this week, great links!
From what I researched, it pretty much depends on, basically, your body and how tolerant you are. It depends on how many fumes there are, and how much you inhale. If you inhale enough of it, you could possibly get drunk, although you would feel a little dizzy first. This is because the main chemical in alcohol is ethanol. Ethanol is also known as grain alcohol, pure alcohol, or drinking alcohol, along with many other names. Ethanol is one of the oldest recreational drugs. As iluvmusic said, alcohol is not an inhalant, it is still really harmful to your body. If you inhale enough to get you drunk, it will enter your bloodstream, which can be highly harmful to your body.

Pippin's comments: I have to wonder though: if you can get drunk on ethanol, couldn't that be a major problem in considering bio fuels? After all, when we go to fill up our tank on gasoline, we smell gasoline fumes. Therefore, if drivers fill up their tank and catch a whiff or two of alcohol, then that will be almost the equivalent of putting (slightly) drunk drivers on the road- and that could be rather hazardous. Wouldn't that mean, then, engineers would have to design a completely leak-proof ethanol dispensing system so as to avoid doing that to drivers? Plus, even our gasoline systems are (clearly) not leak proof, so I highly doubt we'd been able to create an entirely leak-proof ethanol system that every fuel station would embrace and maintain properly. Hmmm... well, just something to think about!

How do Monkeys keep their hair short?

For those of you who didn't get the question, this was a tricky one.  The trick behind the tricky question was that you had to search not monkey hair shortness, but why hair grows to a certain length in general.  (and by all means, you definitely shouldn't have searched for monkey barbershops- that would have gotten you nowhere).  Basically, as Totalmystery and Saffire said, monkeys shed (and we do too).  To be a little more detailed, the parts of your body that grows hair, your hair follicles, have a specific programming, so to speak.  Every hair, first of all, has its own follicle, so this follicle produces new hair cells, pushing the older ones, which we see as hair.  Hair follicles will continue to produce cells for a certain period of time, called the growth period.  Then, the follicles will stop, which is called the rest period.  Once a hair follicle enters this rest period, it stops growing and the hair falls out- thus, once the rest period ends, the follicle can start anew.  This system of grow-rest-grow-rest controls how long hair can grow, so while the hair on your head can grow long enough to cover your face, the hair on your arms won't do much.  Animals that shed coordinate this rest period so that all their hair sheds at the same time, creating a mess in your house at times.  So, monkeys keep their hair short simply because it isn't going to grow any longer (for monkeys with short hair). And that's it for today! Hope you learned something!
