Post whacky or neat math stuff

[mrmitchell]

I'm in Arkansas Governor's School (hence my absence lately) and we've been doing all this math stuff that you would normally never see in high school, and yesterday we did one thing (0.999=1) that I'd seen on here before. I know you all have more interesting ones, so please, share.

No.

Oooh, another one of these threads.

[KrazyHorse]

Why? Do you think 0.999=1?

[Japher]

Sounds like Kid math.

Why is 6 afraid of 7? Because 7 8 9!!!

[Kuciwalker]

No, of course not, I'm just going to enjoy watching this thread.

You DO know that he's talking about "0.999..."?

[KrazyHorse]

Anyhow, one of the simpler interesting results from math is:

Take the curve y = 1/x on the domain (0,1]
Rotate this curve about the x axis (line of y = 0)

You get an object shaped like an oboe. The surface area is infinite (logarithmically divergent) but the volume is finite.

Then he should have said so.

1 + 1 = a window.

Try it!

There is only one way to put a finite set into a linear sequence, up to isomorphism.


(it's a somewhat obvious and quite true property of finite sets... I put it here because I just love that wording. It's like saying that all cars are the same colour if you allow for repainting )

Try it!

It worked!

Also, if you enter 5318008 into a calculator and then look at it upside down, it spells "boobies".

Really! Try it!

Yes, I’m tired. For several years I’ve been blaming it on getting older, lack of sleep, weekend projects, stale office air, poor nutrition, carrying a couple of extra pounds, raising a family, recent ailments, and a dozen other reasons that make you wonder why life is getting tough.



But now I found out what’s really happening! I’m tired because I’m overworked. The population of the USA reached 300 million last October. 79 million of the population are retired. That leaves 221 million to do the work. There are 19 million toddlers and 76 million students in schools, which leaves 126 million to do the work. Of that total, 21 million are unemployed leaving 105 million to do the work.



Then you take away 34 million in hospitals and that leaves 71 million to do the work. 43 million are in prisons and that’s 28 million left to do the work. Now take away 14,683,468 federal, 5,344,722 state and 5,370,743 city workers who run our government and you’re left with 2,601,067 to do the work. Take away the 2,601,065 people in the armed forces and that leaves just two people to do the work - You and Me!



And you’re just sitting there reading this! No wonder I’m tired!!!

Actually, I work for the government.

So that leaves you.
