Now I'm completely bemused. What did I do to warrant such a nasty, snide comment from you? Please do tell me.

Now, about the HUP in QM (without claims that it applies to photons or that it does not).

I think you'll find that it does.

When I say I make no claims, this means I make no claims.

Erm, OK.

The problem with the maths is that it can obscure what is a relatively simple concept [...]

Math does not obscure it. It makes that statement precise, and the reason it holds obvious.

Agreed. I mis-spoke. What I meant to say is that to the mathematically uninitiated, a mathematical discussion may not be understood, whilst it maybe relatively easily explained, at least in outline, in other ways. It's a matter of communication.

You can describe the position of every point in the space with a triple, why not every function (in some functional space) of one variable? In fact, you can but the map would be very weird and highly singular.

And to make a full description you'd need to define the function space, which would involve many more symbols than three.

I was going to check privately if that was you who requested it. But as you have posted it here, I will remove your membership now.

Bob, you have just proved his point!

You should have taken his comment as a compliment. Acting as a petulant prima donna is not a good response.

No doubt I will now come under fire. I will not be replying, so fire away all you like.

I genuinely wanted to know.

Mostly orange light as the light of the old-fashioned light bulbs.

They're not just visibly orange/amber-ish, they also give off significant IR, which has caused them to be demonized for inefficiency, which is certainly true during air conditioning season, where one electric draw is fighting another, which is ridiculous. However, there is lots of evidence to suggest that IR is necessary for optimal health, and when people stay indoors during winter, they may be the better bulb, because they give off IR that people otherwise wouldn't be exposed to if they stayed indoors during winter, or are completely covered in the little time they are outdoors. Also, warmer light enables greater melatonin generation in the evening. The inefficiency is completely irrelevant during winter, if thermostats control the heating, because the "inefficient bulbs" are no worse than electric heat; you can think of electric heat as an extremely inefficient bulb that gives off no visible light.

Gas/oil heating, of course, is not the same as electric, but electric is a rough proxy for them in terms of energy, and they can also be driven by thermostats

Just don't put the bulbs in the windows, and all the energy that they "consume" to make light, as free lunch, on the way to heat.

But in the summer, you pay twice for their inefficiency.

Almost like what someone once said, "one electric draw is fighting another".

For general lounging and relaxation, I prefer the warm bulbs, but my vision works better in cool light.
BTW, I like the light of those bulbs, but I do not use them anymore. I use warm LEDs, and even though the spectrum is not the same, they are not as bad as the "daylight" ones.
