I am a high schooler in a high school math class, and i know that this stuff is way over my head, but i have to do a small five-minute presentation in which i simply give a quick introduction to topology. I am not getting detailed at all. I know about point-set topology, but i would like to be able to talk briefly about algebraic topology. I will show the mobius strip tricks. That's interesting, but i want to know some real-life things that topology has been used to help with.

some conflicting notes:

>Apollo 14 astronaut Allen Shepard played golf on the Moon. In front of a worldwide TV audience, Mission Control teased him about slicing the ball to the right. Yet a slice is caused by uneven air flow over the ball. The Moon has no atmosphere and no air.
>A camera panned upwards to catch Apollo 16's Lunar Lander lifting off the Moon. Who did the filming?
>The pressure inside a space suit was greater than inside a football. The astronauts should have been puffed out like the Michelin Man, but were seen freely bending their joints.
>The flags shadow goes behind the rock so doesn't match the dark line in the foreground, which looks like a line cord. So the shadow to the lower right of the spaceman must be the flag. Where is his shadow?
>Why is the flag fluttering when moon has no air?
>The Lander weighed 17 tons yet the astronauts feet seem to have made a bigger dent in the dust.

I used to think the "Milky Way" refers to the galaxy which our solar system is in.

What has it got to do with Greek mythology?

In fact, isn't it more of a subject on Science than mythology?

as were looking into million of years at there past, as the light takes so long to reach us, could it be possible that we are looking at places that hold intelligent life already? just seeing the light that comes from them at millions of years past when they were at there dinosaur age. if so do you think it could be the same visa versa?

* It is regarding EID AL ADHA which falls on the 10th day of the lunar month.
* The base for the 1st day of luner month to count is to see the crescent in the previous day "Somo leroayatihi wa ftiro leroayatihi".
* Have the governments & religious leaders (specially in SAUDI ARABIA) seen the already set moon with their blind eyes on the 9th of December! On which supid facts they relied on to decide that the EID is on the 10th/dec.
** here are the calculations, showing the moon sat befor the sun on the 9th , and sat after the sun on the 10th for Mecca city (these calculations showing the nearly the same for the area from INDONESIA TO MOROCCO) :-
9th

Sunrise: 6:13
Sunset: 17:04
Moonrise: 5:53
Moonset: 16:40
New Moon: 8:41pm
10th

Sunrise: 6:13
Sunset: 17:04
Moonrise: 6:47
Moonset: 17:32
SO the 1st day of the lunar month should be the 11th of december & the 10th day (EID AL ADHA) to be on 20th december , Thursday.
Day of ARAFAH to be on 9th Wednesday!!

I keep my packaged water bottles in my garage, and my garage is pretty cold this time of year...down into the teens and possible single digits (Fahrenheit) at night. In the package some of the bottles are frozen solid and some don't freeze at all. Why does this happen?
