Doner Kebab "elephant legs". How on earth can they be heated up, cooled down, then re-heated in perpetuity without serious food poisoning afoot?

Because when you heat something up enough you kill the bacteria.

Rice might be an exception; however if you’ve ever completed any good standard hygiene courses, you wouldn’t eat any kebabs..

That doesn't answer the question though.

In effect, heating will not always kill all the bacteria; that’s what I learnt under food hygiene. Whether you get ill or not, is possibly down to your constitution, amount consumed, luck, and types of bacteria. If rice goes pink, oooops bad news.

I believe "set' is the word in the english language with the most meaningsdescribed uses.

Back in pre HID and LED days why did the glass in car headlamps have ridges, striations, crazed patterns
on them rather than just be clear and unmarked ?

They acted like lenses to focus the beam

Then designers decided they wanted to have nice sleek attractive clear lenses and the manufacturers had to make the shape of the reflectors do the job of directing the light correctly.
Or possibly the other way round.

Another, again headlight related, but auto-dip systems. Driving home this evening, about half an hour ago, I was monitoring the auto-full beam system as it's been misbehaving a bit of late. Coming out of a corner up to a village there was a roadside house, with massive security lights lit up facing the road. I thought that these surely would fool the system, but no, the car didn't auto dip the headlights. On this drive every other car in the opposite direction was picked up and it auto dipped.

The question being, what part of the systems algorithm figures out that a bright road facing security light is not a vehicle, but can tell headlights are actually so?

I would imagine height above the road would feature pretty highly.

That is a fair point, but many of the other cars it 'knew' to auto-dip for were uphill from mine, after I'd exited a bend. Wouldn't that seem the same to the feature (auto-dip lights)

Stop Cocks.

Who, when designing houses, thinks "Mmm. This device to temporarily halt the flow of water into the house might on occasion come in handy, I shall find the most inaccessible part of the property in which to hide it, ideally in a place where it can seize up as well!"

Why?

In Aus most detached houses (which means most houses) have the water meter, the garden tap, and the stop cock in the front garden and a lot of house have no front fence. I doubt that would work in the UK because they would get messed about with but fortunately drunken idiots focus on kicking over letterboxes rather than either turning off people's water or just turning on the garden tap in the middle of the night.

My auto-dim is useless, and yes, it gets fooled by static security lights but doesn't auto dip with neon
street lights or oncoming cars with dipped halogen lights,it only works with HID or LED headlights or full beam halogens.

So watching Chernobyl tuther day and they said nobody can live near the blast site for circa 20,000 yrs.That got my thinking.
Hiroshima,Nagasaki and hundreds of other nuclear blasts have occurred and ppl are now living near some of those sites.So why not Chernobyl?

[coppernorks]

The two Japanese bombs were airbursts, radiation contamination was short lived, Chernobyl was a reactor explosion that contaminated the immediate area.

I'm sure it's explained in the TV series.

Slightly more complicated than that.

An atomic bomb is a point source event, and a relatively clean thing.

Chernobyl was a dirty ongoing event that was pumping out toxicity for days or weeks until it was brought under control.

It's comparing apples to oranges.

Edit: glazbagun put it better than I did.

Cherenobyl was an explosion followed by an uncontrolable reactor fire spewing radioactive contaminants into the air for ten full days as it melted into the earth.

Hiroshima, Nagasaki and all of the nuclear tests since have been smaller amounts of fuel designed to react as completely as possible and exploded in an instant in an airburst. Still not nice, but you're not going to have the same concentration of nasty radioactive elements lying around.

I see,thanks guys.Very interesting.

Why do all policemen sound the same? Do they go through some centralized elocution training or something?

They all talk in the same measured tones. I think they must have it repeated often that they must use certain non confrontational and unambiguous phrases.

Lol that is actually very true, I deal in a customer facing roll and I can usually tell if someone is a Policeman, generally just by the way that they tend to talk and also carry themselves.
