I used the math tutorials from a cd to get ahead. It worked well and gave me an obvious headstart, but it didn't cover everything. I finished a year during a couple weeks in the summer. It's called MathAdvantage 2002... couple years back isn't too bad. Problem is, it only goes up to the 2nd calculus year.

It seems like hot water has these little white dots in them but cold water doesn't? What is that? Tiny bubbles? Squid sperm? Bacteria colonies?

Yeah, that'd be a good idea.

What chemical or chemicals, on contact with blood, instantly explodes? This explosion doesn't have to kill them, it just has to go boom. I'm writing a science fiction story about an alchemist/knight during the Middle Ages who put something on his sword so when he goes into battle, people who he slices explode.

oh heh, just shoot me now for not knowing what "square numbers" means

Aw, I was trying to see if there was a control to slowly turn off the monitor.

I don't think n has to be an integer, only m. s is the integer, n is the square root of the integer. Typo perhaps.

Is there some way you can control how fast the monitor turns on or off when you push the button?

I saw this on Unsolved Mysteries. A woman claims to be someone else. An unrelated man claims to be someone else. They claim to have swapped souls with someone else. They change their names. Interestingly, when I saw it, I thought to myself this is what happened a few years back. I became someone else. *It may be attributed to my having more than 5 different names when I was a kid. Assume that this isn't a false claim. What psychological term or idea is this called if someone believes they're someone else? Has this happened to you?

The French taxed and drove people into the mines to make the colony profitable for France? Despite the fact that Vietnam exported tons tons of rice, Vietnamese peasants starved / are starving? The U.S. supported France having colonies in Vietnam? The U.S. put in place a leader who was Catholic and from America, which would alienate him from the majority of the Vietnamese? Then they overthrew him to take charge of the war? There were millions of Vietnamese casualties? There were more explosives dropped on tiny Vietnam than in all of the theators of World War II put together? The U.S. used chemical warfare against the environment they claimed to be trying to save? The U.S. tried to use "economic strangulation" after the war? Has the economic strangulation stopped yet?

How does that happen?

Interesting. Last night I was able to control my dreams twice. I flew up for 5 seconds, knew I could control my dreams, wanted to fly to the sun, but failed and woke up. Then I dreamed another one with flying around a city, but the flying was like an astronaut jumping 20 feet off the ground for a couple of seconds before landing. Regarding some posts that talk about conscious sounds in the dreams, my second dream had music from the radio that was playing. I leave the radio on a lot, so this probably isn't a factor in those flights. What may be the factor is what happened yesterday. I was doing my history homework, got interested and read about the history of my people, read the history up to very recent years, and realized my entire world was turned upside down. Everything I had ever believed was just skewed, and my family and ancestors were lied to by the government (I don't want to go into detail of what I read). But this was very emotional and may have caused me to levitate, meaning be lifted up. Perhaps the flights were a subconscious defense in the form of a metaphor.

Nevermind this thread.

Could people float across the Atlantic or Pacific Ocean and live?

yeah the book I got it from was written more than 40 years ago, when computers took years to add numbers

Yep

Referring to a bird? or is it a living pteradactyl?!

Big creatures in water can exist unknown and unseen to people. Big creatures on land can exist unknown and unseen to people (it may just be the case that these animals are unknown to the "westernized/civilized people" who come there to colonize, explore, etc., but it may be well known to the "barbarians" who live there). There are other places in the world where there have been drawings, stories, etc. about underwater dragons, creatures, etc. The world is much bigger than our perspective of it. Personally, I don't see how it's possible that all the dinosaurs died out during the K-T extinction. I mean, there must've been mutations that allowed some species to adapt to climate changes, food shortages, atmosphere, etc.

This is taken from a puzzle book. I used to have 750 marbles in my bedroom but I lost some. The number of marbles remaining is one more than a multiple of three, three more than a multiple of five, five more than a multiple of seven, and seven more than a multiple of eleven. How many marbles did I lose?

If you can find a high school biology teacher, they have the materials needed to make the dishes.

No, whoops I'm just horribly dyslexic. I didn't see "is the same as."

Actually, all those you just mentioned are the same. You just rotate it, and it becomes the same thing. That's the difference between linear and circular. In circular permutations, all of those are the same. In linear permutations, all of those are different.

No problem.

Another way of looking at it is through reference angles. Here's another way of looking at it. I use the letters a and b as angle names. You have your unit circle. Draw a point on (0,1). Draw a point on (cos a, sin a), preferably a<90. Draw a second point at (cos b, sin b) where a + b = 180. Now, if a + b = 180 and a<90, then b - 90 = 90 - a. Therefore, (cos a, sin a) and (cos b, sin b) are equidistant from (0,1) Well, sqrt(cos^2 y... you'll have to do this on paper. It'll get too confusing at this rate. Use the distance formula. Then square both sides to get rid of the square root. Expand. Use the idea that cos^2 X + sin^2 X = 1 The two 1's on each side cancel out. Divide both sides by -2. You're left with sin a = sin b Since a + b = 180, b = 180 - a. sin a = sin (180-a)
