I know that he was one of the greatest prodigies of his time (died in 1944). I also know that his mind was trained from an early age. Could it be possible that other people who start later can at least come close to his accomplishments?

They are two completely different numbers. If 0.999...9 is equal to 1 then accordingly 0.999...98 = 0.999...9 , 0.999...97 = 0.999...98 which is equal to 0.999....9 which in turn is equal to 1, thus 0.999...97 = 1. Eventually, we could get that 0.000...01 = 1 or even that all numbers equal to 1. Isn't that absurd? Mathematicians who say that 0.999...9 = 1 are not taking into account the infinitesimal difference those two numbers have (0.000....01) which in reality distinguishes each number as a unique mathematical entity.

I have been stuck on this question for quite a while now and I'm looking for some hints.

Two particles execute simple harmonic motion of the same amplitude and frequency along close parallel lines. They pass each other moving in opposite directions each time their displacement is half their amplitude. What is their phase difference?

Thanks in advance.

This is the question I am having trouble with: Draw a lewis structure for the ionic compound Ba(OH)2.

here is my answer


**

H **O**

x *

Ba x* H


**O**

Would the two oxygens be coming off of (or bonded to) the Ba & H to make the noble gas configuration? (8 electrons)
If not, where would the oxygens go? because oxygen only has 6..

any/all answers much appreciated:))

I have differnet equipment at my work site. I found yesterday the the power is wired differently one on them. All the systems run on 100VAC 1 phase. The system that has the VAC ground running to the power pull has not sign of static problems. The other system have VAC ground connect to the chassis ground. Would this be the cause of my static problem.
