If you were to look at the spectrum of the gas flame of a stove or the blue part of a Bunsen burner flame, what sort of spectrum would you expect to see—Absorption, emission, or continuous? Why?

x^2=x+x+x+...(x times)...+x
Let's take a derivative d/dx
2x=1+1+1+...(x times)+...1
so that
2x=x
Why derivative on the lefthand side is not equal to the derivative on righthand side

according to einstein's laws and nothing can travel at the speed of light but, we can travel at or faster than this speed. time is actually an arbitrary concept based on strain of the human mind trying to place all things in a forward moving linear direction. time is relative however. a star that we see that is 600 light years away has light that is 600 years old. in other words what light we see from said star, is 600 years old. lets assume now that i can travel faster than the speed of light, lets say C^2. this would mean that if i traveled to that star i would be seeing it as it was 600 years ago. using this logic if i traveled to the star as it was 600 years ago and then traveled back, i would be seeing things as they were 1200 years ago.

now realizing that this is only a hypothesis and cannot yet be proven, does anyone agree that this can be used to travel into the past? if i am seeing the light from 1200 years ago does this mean i see people who aren't there?

Suppose that you don't know the relation,
mechanical work W=F.S.

In this circumastances can you derive the equation Ek=1/2mv^2 (without using the relation W=F.S)?

I think any of the two relation (W=F.S and Ek=1/2mv^2) is axiomatic and they are circular. So that you can't get one of them without using the other. When one of them is defined axiomaticaly you can get the other.
Am I correct? please inform me!!

If I am travelling North - South at about the speed of light, and somebody else is approaching me South - North also at about the speed of light, what is our converging speed? And how do you derive it?

Hi,

I mean two things by saying astral projection:

1) Projecting into the next room and seeing whats there.
2) Projecting into astral plane and meeting with other people.

PLEASE DO NOT ANSWER WITH LINKS.

If you are going to claim some facts, please name your sources.

Thank you very much.
