1. ## How do I demonstrate gravitational influence mathematically?

Use inverse squarer relationship. Your description doesn't describe the motion of the first two relative to the third.
2. ## Two meteorites and sound waves

It will depend on where the observer is relative to the meteorites. Speed of sound is not subject to Lorentz transformation.
3. ## Want to know

Zeno's paradox goes away when time is considered.
4. ## What type of scientist creates anti-venoms?

Why is the name of a particular specialty important? I presume venomology is narrower than toxicology. Try Google.

6. ## Olympiad question (prove)

The link appears to be a list of numbers - no picture?
7. ## Olympiad question (prove)

Draw a picture!
8. ## Square root and power of a negative number

My statement is about all (including complex) numbers.
9. ## Square root and power of a negative number

Every number (except 0) has two square roots. Using the convention (ignore negative root) leads to these kinds of problems. l
10. ## Instantly Factorize Any Product Of Two Small Or Large Twin Prime Numbers.

square root of n(n+2) is approx. n+1.
11. ## Help with some Lebesgue measure problems

Non-empty open sts must have positive measure, so your approach to the first question is correct. The second question is almost from the definition.
12. ## Lebesgue measure and Lebesgue integral

The second and third easily false. The two function could agree on the rationals, but not elsewhere. You need to use another deliminator for Latex \$ doesn't work here [math] and [math] with / work.
13. ## Is it possible that round moving have more strong impulse?

Looking at the original question (I have not plowed through the responses), the ball on chain can hit harder than the hammer because it can be made to go much faster before release.
14. ## Life Near a Red Dwarf Star

Pure speculation. High wind conditions could lead to evolution of very sturdy thick trunk trees which would mitigate winds and allow small (compared to tree size) animals to evolve.
15. ## sqrt(x)= -1 , no soln. ?

Mathematically sqrt(1) has two solutions +1 and -1. There is a convention that only +1 is allowed and the program may be set up to follow the convention.
16. ## The nature of the electric current (Hypothesis)

The point I am making is the speed of the electrons is irrelevant to electricity working.
17. ## The nature of the electric current (Hypothesis)

Most households use AC where the electrons jiggle in place.
18. ## Simple yet interesting.

I don't get it!
19. ## Simple yet interesting.

Is there a question? What are N, x, y?
20. ## mereotopological objective probability

I hate to say this, but it sounds like meaningless wordplay.
21. ## mereotopological objective probability

Sorry! Completely strange to me.
22. ## mereotopological objective probability

mereotopological - Did you invent this word? What does it supposed to mean?
23. ## The Fermi Paradox:

I agree with Fermi. Interstellar distances are a the main problem.
24. ## What are numbers between 0 and 1??

Define numbers. As is the question doesn't make sense.
25. ## When Indo-Europeans first came to Europe?

I know very little about this subject. However movement like this usually means they need more room.
