is it an optical illusion or is it really there? What makes it look like that with the waves and the colors.

Let {f_n} be a sequence of continuous functions defined on [0,1] such that f_n(x) -> 0 as n -> inf. for all x in [0,1]. Show that for each positive number e, there is a subinterval [a,b] of [0,1] and an integer N such that |f_n(x)|N and x in [a,b].

Is there anywhere on a sine wave that is 'linear' - like, say, where a 'particle' is just 'coasting'? How 'big' is that spot? What are the maths thereof?

I have a T/F question which says, "Justify your answer. For all positive real numbers x, log(x) > 0

How would I go about finding "all" instances of this, or is it generally assumed that finding *any* single instance of proof/disproof is enough? I already know that if x=1 this statement is false. Log(1) = 0 and 0 is not > 0. Is that enough?

I'm studying this alone in my own free time so any additional advice for studying this type of math is appreciated.

Last night, observing the full moon in my home city, northeast of Mexico it had like a ring not too close to it, very bright but seemed like a ring of fog. I could appreciate information regarding what I saw. Does it happen each month?

Can anyone figure this one out.. it has me stumped... please please.. this is the last one and I can not figure it out at all... thank you all for all your other help..

The base of a triangle is 7 cm greater that the height. The area is 39 cm^2. Find the height and the length of the base.

The height is ??? cm.

The length is ?? cm.

THANK YOU SO MUCH!!

If every matter that has mass is considered to have a Gravity in them, it would make WD5 gravitationally attracted Earth and Mars. If Gravity is the reason that held the position of every planet around the Sun, and the planets orbit in a form of centrifugal force, any planet that are hit by WD5 would send it out of it's original orbit. Not only that, every big object that travel across the solar system will hit a planet and not avoid it like the one that almost hit Earth on 2004 (1994).

The theory of Gravity that are widely considered is calculated base on low technology or very little technology. Those people made their calculation without even kwowing what really is space environment. You don't have to agree with me, but in my calculation the theory of Gravity that are widely considered has no safety in mind.
What is your opinion ?

Okay, I have a theory that since the universe has mass (not just on Sundays), that:

1. The universes' shape is defined by it's own gravity
2. The universe battles between the pressure of the big bang, and gravity caused by all matter in the universe.
3. As you go closer to the center of the universe, because of (cyntrifical force/gravity), time maves more slowly (relatively); As you go futher away from the center of the universe, time moves faster.
4. A spherical barrier made up of all of the 4 properties of matter exists on the edge of the universe (unpenetrable, for obvious reasons)
5. In the hypothetical 'outside' of the universe, time moves atr an infinite speed.
6. At the center of the universe is a core singularity where all matter originated from.
7. The singularity of the universe acts as a black hole (infinate gravity, non-moving time).
8. The singularity has no mass, and is made up of remenant anti-matter nebulae from the big bang.

Let me know what you think.

Can someone explain Kepler's Third Law of planetary motion to me? I have the definition but I just don't understand what it is. Help!

I believe various nations are seeking to explore beyond our planetary atmosphere. With the end of the "Cold War," America and Russia no longer feel the need out do each other. And so, I am curious about who is making the most strides "now" ?
