toxicity is a problem at high concentrations

Not if you are comparing it to lead-acid or lithium batteries.

- Half of the time, the Sun is above the horizon for a radiotelescope on the far side of the Moon

True, but for on the "near" side of the moon, the earth is in line of site 100% of the time and on earth the earth is in line of site 100% of the time.

So having the sun in your eyes only 50% of the time looks like a really good option.

Re.

Bleach is probably more dangerous to the health of most people in most of their everyday situation. Too many chemicals these days not enough natural exposure.

I see PC is still bragging about refusing to listen to me for pointing out his previous errors, so will someone please draw this to his attention.

A bouncing antimatter asteroid would leave a series of large deep lakes joined by shallow streams.

I don't know if this song is well known among out transatlantic cousins
https://en.wikipedia.org/wiki/Ten_Green_Bottles
I gather they have a comparable "99 bottles of beer on the wall"

Wiki points out that there are other versions; some vulgar.

One such (stripped of vulgar language) runs as follows

Ten sticks of dynamite hanging on the wall
Ten sticks of dynamite hanging on the wall
And if one stick of dynamite should accidentally fall
There?d be no sticks of dynamite and no [expletive] wall

Technically, it's wrong. Dynamite is difficult to initiate and dropping from any sensible wall wouldn't initiate an explosion.

But I was reminded of it by the idea that a bouncing antimatter asteroid would leave lakes and streams rather than
"No bouncing asteroid and no [expletive] planet."

That's fine- until (as has been pointed out) you start trashing the earth by squandering resources.

Religions have to become more accepting of gay people. Because sometimes, you just have to work with what you're given.

Religions have become more humane.
And that's because the rest of us worked against  we were given.

Science Experiments / Re: What phenomena can be demonstrated by a cheap high voltage generator?

The third video demonstrates the effect of the high voltage generator on a gas discharge lamp.

Can anyone try to explain how a steel pliers can make the UVC lamp glows brighter?

More surface area thus more capacitance, thus more coupling of the electricity into the lamp.
What I can't explain is why you choose to expose yourself to hard UV for no reason.

We don't know anything about ideal gases, because there aren't any!

So... that's one thing we know about them.
I think we know other stuff about them too.
They are colourless. (If they interacted with photons they would interact with those emitted by the walls of the container (and one-another) and that's forbidden by their definition.)

Arguably, we know everything about them for the same reason that Tolkien knew everything about Hobbits.

Interestingly, if you consider this

 

You run into a different conundrum.
In the first excited state- labelled C- your particle has zero chance of being in the middle of the box.
But it has a 50% chance of being one either side.
So, how does it get from left to right without ever  being in the middle?
You can pretend it doesn't matter- it's actually really on one side of the box and, unless it's kicked into a higher state, it remains there.
 But it's worse than that.
The observable universe can be treated as a huge box with very high walls.
Because the box is big, the energy level separation is tiny.
So any particle you see will actually be in a very high excited state.
It will be passing through a massive number of the "zeroes" of probability density every second.
How does any particle travel past the bits where its probability is zero?
