Homework Statement Matt spies a woodpecker on the branch of a tree in a park. From the ground, the angle of elevation along his line of sight to the bird is 26 degrees. He walks 20 ft towards the tree, and in the same plane as before, now sees the bird at an angle of elevation of 40 degrees...

But how to do that is the problem.

Homework Statement Use Factorization to simplify the given expression. Homework Equations (x^3 + 3x^2 + 3x +1)/(x^4 + x^3 + x + 1) The Attempt at a Solution I can't get to the first step. I forgot how to factor exponents higher than x^2.

So in reality, there can't be a number directly after 0?

Is it true, that there is an infinite amount of numbers between 0-1? Think about it, what number comes after 0, and before 1? Whenever I try to think about it, my mind goes blank. Discuss.

But why ? Explain please.

Why does it being lighter than air have anything to do with it floating upwards. Isn't mass supposed to be attracted to the Earth, therefore falling?

Why does gas float upwards instead of falling towards the Earth ? Is it a mass difference ?

So, is space still expanding at this speed? Or has it slowed down a bit?

I've read that theorists predicted the big bang to expand faster than the speed of light. Is this true? If so, how can we say that nothing can travel faster than light today?

Just goes to show that there's no natural distribution.

Well, we know that most planets that are the close to the sun are usually really hot and rocky, and tend to have very tiny atmosphere, if at all. Going past the rocky planets you tend to see gas giants. I haven't heard of there being a natural distribution. It all depends on the mass and...

Infinite dimensions? I thought it was limited?

It might of been a gecko. If touched by human hands they tend to die.

What mesons, leptons, and/or baryons are you talking about?
