The simple answer is that, according to our experiments, atoms are round. The case for non hydrogen-like atoms is complex, but the simple answer is that the orbitals we get have to be linear combinations of the corresponding orbitals for hydrogen (in order to meet the same momentum + energy criteria). So they look like these https://commons.wikimedia.org/wiki/File:D_orbitals.svg But what is never explained in those diagrams is that the actual sum of the functions is (So I was told as a student) spherically symmetrical.

No Most of what we see as science is a complex interlinked grid of theories deductions and observations. And the important thing is that they all interact successfully.

If you are going to try to be petty: get it right. It's a strontium ion. " The photo shows a pinprick of a positively charged strontium atom " If it was neutral, it wouldn't be held in an ion trap. Yes they are. Those funny looking dumbbell shapes you see are poor representations of the probability density. The actual functions sum to a spherically symmetrical distribution (unless there's one outside influence on them) But the biggest problem is this If I look at the end of my finger, what I see are photons that were emitted by virtual stated populated from the ground sates by incoming photons. The process is the same- albeit that the energy levels are different.

Then I suggest that you get someone else to read your stuff before posting it. That way you might avoid saying things like "I read it twice before reading it ."

Did you read that through before you posted it?

The MSDS lists a couple of strong alkalis as the active ingredients and those will corrode aluminium. (To be fair, so will bleach) The problem is condensation. Have you considered something like this? https://www.selfadhesive.co.uk/tapes/single-sided-tapes/foam-tapes.html

Am I the only one who read the title of the thread and thought "that's going nowhere fast"? IQ is barely meaningful, race is barely meaningful and brain size is barely relevant.

And significant luck. There's no guarantee that they would be fissionable in a bomb. We simply don't know. It's possible that you could have a teeny little nuclear reactor- which would be cute, but utterly impractical.

If you have symptoms which you think may be due to poisoning you should seek medical treatment. If it turns out not to be poisoning, they still need treating.

How many "restrooms" does the Whitehouse have?

I wouldn't.

Or an observation.

"Does Hybridization Always result in superior genes?" It is impossible to define "superior genes" in isolation from the environment.

You seem strangely determined to overlook the heat gun which is odd because the importance of heating is the point of the OP's question. You can demonstrate the effect of pH on the colour of tannins by making lemon tea or, less drinkably, by adding ammonia to tea.

Acids are well known for catalysing the charring of carbohydrates. https://www.sciencekids.co.nz/experiments/invisibleink.html And it's a pH effect more than anything else. As you say there's no need for a heat gun

I presume it's this sort of thing. (The commentary is inaccurate, it' s the HCl that chars the wood rather than the ammonia.) It would probably work in an oven but I don't know if "350 degrees" wold be hot enough. Units are important. There's a risk that the HCl fumes would corrode the oven too. The HCl is very corrosive towards metals (and not very good for people either).

What worries me is that people may be leaving the party because they see it as no longer supporting their hero: Trump. OK that makes republicans unelectable which is good, but it is still terrifying that people might think that way. They might not be leaving because they recognise that the Reps are crazy; they might be leaving because use they don't think the reps are crazy enough. What happened to Rep party membership when he was selected?

It is probably better to buy the girl some flowers which might not work, than to buy a book that certainly won't work The authors usually rely on the fact that, when you realise you have been made a fool of, you will be too embarrassed to take them to court.

No, or , at least, not at atmospheric pressure.

There goes the neighbourhood. https://en.wikipedia.org/wiki/Edgar_Cayce#Criticism You can't cite "clairvoyants" on a science site, and expect to be taken seriously.

Yes. Do nothing about it. The outcome will be the same as anything you might try, but doing nothing is very cheap. Incidentally, you are taller than I am.

"why people are not protesting over cancer and Heart disease?" They did. We no longer allow smoking in public places.
