The issue is Chlorine "breaks down". The results of reaction Cl2 --> 2Cl from energy from "sunlight" is reactive and will reverse the reaction and get back to Cl2 or maybe 2H2O + 2Cl --> 2HCl + O2 hydrochloric acid

You say the author intended Cl2 --> 2Cl Naw. That reaction requires energy.

Chlorine is an element and, thus, by ordinary chemical means, never "breaks down". Maybe some people are assuming the old remark: "The solution to pollution is dilution."

For education of present young people, the core need is to give them what will help them for the next 60 years. We can be fairly sure that one important theme for the next 60 years will be the economy. The economy has two important sides:

Thanks. I'll keep that and use it! My violin is a decently good one, grown up size! And I have a fine tuner only on the E string.

My summary view of much of Microsoft, and more of tech, is that, while a lot of the software is really good, too often the corresponging explanations and documentation are not. There seems to be a theme that the user should learn to use t

Right. But, with this approach to a proof, to be strict, for "prime factorization" need that it is unique, and that is the Fundamental Theorem of Arithmetic -- need that.

If I had explained it further, then the proof would have been longer! Right, we need the Fundamental Theorem of Arithmetic, that each integer factors uniquely into a product of prime numbers; right, that statement leaves out a little about

Let's have a simple proof so that we don't have to argue about more complicate issues: For integers p, q with q not 0, suppose 2 = (p/q)^2 Then 2 q^2 = p^2 and the left size has an odd number of factors of 2 and the right sid

Of course, my point is the propensity of undefined terminology in writing about computing and in particular at Hacker News. It's a very valid point. You don't attack the point but ME. Not good.
