Generalizations

Next time you say a generalization about people, keep in mind the average person knows about 600 people (a), and there are 7.3 billion people in the world. You know about 0.00000821917808% of the people on the earth. But you've met more people than that.You will meet about 80,000 people in your life (b). Let's see: that's a whopping 0.00109589041% of the world population.

Question about Time Dilation...

For a while, a question has been without answer in my mind. In recent conversation, I have brought it up but had a hard time explaining it. I decided to write it out to help organize my thoughts and help other people understand my thinking in hopes that either I find the answer in sorting it out or someone else comes up with a answer that solves the paradox in my mind. For the purpose of the example, let's assume that instant communication with quantum entanglement (or some other system) is possible.

Mr. Smith  is traveling through space at high speeds. Mr. Brown is on earth. When Mr. Smith  passes earth at supersonic speeds, he fires two photons, one in front of him and one behind him. he has set up sensors that move with his ship that detect when the photon he fired hits them. These sensors do not change the course of the photons, they merely detect them.When they detect them, they send an instant message to the control board witch records the time it received each one. According to time dilation, if they are each equal distances away from the origin of the photons, they should both receive the same time.  

Mr. Brown, who is on earth, also has two sensors. They are also each an equal distance away from where the photons were released. They also should also receive them at the same time.

The problem? For Mr. Smith's readings to be the same, his space ships time will both have to speed up (for the photon sent behind it) and slow down (for the photon sent in front of it).

Any thoughts?

 

 

 

 

Volume Problem...

If you played a song on very low volume and then when it started fading out slowly turned it up, what would happen?

On choosing a door.

Just found this presentation lodged between two posts on my old blog: (it still confuses me...)

My Magic Number Theory

What follows is my mostly developed Magic Number theory or Jem Theory that probably already exists but I haven't found yet.

Every Platonic Solid (there are 5 total) has a magic number... You may be thinking "how do we get this number? why is it magic? what is a 'plant on it' solid?" Don't worry, I will answer all of you questions in good time.

First of all, what is a Platonic Solid? It is a 3D object where every face is the same Polygon. Read more about them here: http://www.mathsisfun.com/definitions/platonic-solids.html

Ok, ok that's great. So what about this whole 'Magic Number' thing? If you add up the total number of corners, and then multiply it by however many edges and faces each corner is touching, you get the Magic Number for that solid. But that's not all; if you add up the total number of faces and multiply that by the number of edges and corners each face touches, once again, you get the magic number. You also get the magic number if you add up the total number of edges the solid has, and then multiply it by the number of corners and faces that edge touches (for this one it's always 4), as you can guess, you get the magic number.

A list of the magic numbers for each shape:

Cube: 48
Dodecahedron: 120

Shapes where the sides are triangles:
Tetrahedron: 24
Octahedron: 48
Icosahedron: 120

Oh, and if you have any ideas how these numbers relate please let me know in the comments or something (more detailed list below);

Name	# faces	Face shape	Jem Number
Tetrahedron	4	Triangle	24
Octahedron	8	Triangle	48
Icosahedron	120	Triangle	120
Cube	6	Square	48
Dodecahedron	12	Pentagon	120

.99999999......... = 1?

Today while thinking about PI and infinite numbers I came to the conclusion that 0.9999999.... (going on infinitely) = 1. Why?

1 / 3 = 0.333333333333333.......
3 * 3 = 9
0.3333333333333333....... * 3 = 0.9999999999999999...............

Thus, the math laws I thought I knew are put on trial. And lost.

UPDATE:: I googled this problem, and found this website: http://www.purplemath.com/modules/howcan1.htm
That puts it like this:
x = 0.999...
10x = 9.999...
10x - x = 9.999... - 0.999... = 9 = 9x
9x = 9
x = 1

4.0e30

Looking back at my first post, I noticed I said:

2 quadrillion squared (if anyone wants to calculate that, feel free.)

Given I'm the main follower of this blog, I decided to calculate that (aka type it into Google.)

All Google could tell me is it's 4.0e+30. A few years ago I would of given up at this point, mistaking the "e" for error. Later I learned that the "e+30" means x10^30 or that I should add 30 zeros to the end of the first number.

2 quadrillion squared is 4,000,000,000,000,000,000,000,000,000,000 for all you who wondered (or just me.)

Crunch the numbers with Infinity...

Infinity... do we really know what it is?

Have you ever heard someone say "There are a near-infinite amount of ways to do that"? What does that really mean?

The definition of infinity:

limitless or endless in space, extent, or size; impossible to measure or calculate.

No matter what you do to a number, you can never reach infinity. Therefore, 10 is just as close to infinity as 2 quadrillion squared (if anyone wants to calculate that, feel free.)

How can the Big Bang theory account for an infinite universe? I don't see how it can. Only an infinite God could create something infinite like that.
