Why do circuit breakers go up for on and down for off?

Ah, that's why I like 6000K LED lights. And before that the rather rare and expensive 6000K CFL lights. Although I now add UV since my parrots can see UV. You're supposed to buy very expensive lights which include UV. I just use normal ones and add cheap UV LEDs intended for discos.

Then why isn't it called ganblack?

you catch the thing which

Where do you get your numbers from? This suggests other occupations were worse affected:

I can't see how voltage operated would have ever worked. Earths are not high impedance.

Can't see why that would be. More likely that those who aren't colorblind would be able to see the prey better than the color blind, but that doesnt explain why color blind is much more common in men.

Harmonics, dear boy, harmonics.

Not really sure I trust that last item - it sounded interesting so I read it.

"This may sound strange today, but back then, the pain of the houses contained limestone. Limestone is a powerful disinfectant, and not many others were widely used at that time. Thus, Greek citizens whitewashed their homes to disinfect them and reduce the spread of cholera."

Apart from pain instead of paint...

Limestone is not a powerful disinfectant.

If you bake limestone (calcium carbonate) you get calcium oxide, AKA quicklime. Mix that with water and you get a calcium hydroxide slurry, AkA limewash, and that's the disinfectant.

"The blue used in the islands' houses in the blue Aegean sea was made from a mixture of limestone and a cleaning product called 'indigo.' The indigo was a type of blue talc that most of the islanders easily had at home. Therefore, blue was a very easy color to make."

Indigo was never a cleaning product AFAIK. I'd assumed the blue was lapis lazuli, which comes from Afghanistan and cost an arm and a leg in ancient times. But I assume this guy knows something and

Almost identical text appears in other older articles, except they say the blue was a cleaner called loulaki. Which is also a Greek name. Too hard for me to look further.

The extra colours have a confusing effect. Have you looked at the colour blindness test books, the ones with lots of colour dots where you have to tell which numbers are there? There's one which only colour-blind people can work out as it has wavy red and green lines.

This is because the gene for the extra yellowish cones (don't know which one) is on the X chromosome and men only have one of those. If the gene is faulty you only have two working cones; women have two X chromosomes and provided one has the working gene they are all right.

Not convinced.

But wild animals and plants don't use any scheme like that.

Sure, but that's a separate question to why we evolved with some colorblind.

I am tempted to write Bollocks dear boy, Bollocks.

Probably just a defect that is not strongly deselected. Humans are still evolutionary kluges with enormous variation and lots of bugs. There's overlap between features and bugs.

Civilization, things like agriculture and specialization and language, have applied new selection pressures that evolution hasn't caught up with.

My mom liked a horrible smarmy AM station, WSMB at 1350 KHz. 1350 is

Depends which statistic you believe. And trains can only go where there are tracks, so much loading and unloading and messing about at both ends.

I thought all Japanese trains were maglev. You get a refund if you're more than 10 seconds late.

Until they cross a road, then for some reason cars have to stop for them.

A law to prevent you hurting yourself is silly.

Of course we all went on the tracks as kids.

I came across one in a remote part of I think Wales (possibly England) with no lights, gate, anything, just a single lane road going across a track. At night I just drove straight across, assuming I'd see any train lights. During the day I got out and walked onto ther track to look along it. See? People can think for themselves.

And cars crossing never break down. And nothing ever falls on the track. And animals obey signs. Meanwhile in reality.

Yep, most of the colorblind don't even know that they are colorblind until they apply to join the military and discover that they are colorblind and get rejected so clearly there isnt any selection pressure with that.

Not really, more they still breed fine with a very wide variation across the species.

Dogs in spades.

Yes.

More strictly significant genetic defects.

That's very arguable indeed. The reality is that modern humans are brilliant at being able to ensure that those with very bad genetic defects can in fact survive and breed and pass on those genetic defects.

The US uses intermodal transportation. A truck loads freight and takes the loaded trailer to a rail depot or port and the entire trailer is transferred. It may either be a container that is placed on a chassis for truck transport or sometimes the complete road trailer.

I got busted for putting coins on a track to be smashed flat. They tooks us into the station office. We got a lecture, catch-and-release.

Containers go on trains here, but not usually entire trailers. Due to being the first to develop railways, they were mainly built with bridges and tunnels too small to allow that.
