The term robot came from the Czech language in 1923. The word was coined by Czech author Karel Capek, first used in his play R.U.R. (translated as Rossum's Universal Robots).[7][8][9] The term comes from the Czech word robotník ('forced worker'), from robota 'forced labor, compulsory service, drudgery,' from robotiti 'to work, drudge', from an Old Czech source akin to Old Church Slavonic rabota (работа) 'servitude,' from rabu 'slave'.

koudelka··on The Deep Sea
> Suddenly bringing up a deep water fish would make it explode. every 33ft up the volume of air doubles.

I could be missing something, but I don't think this is quite correct.

Coming up from the first 33ft (10 meters) of depth, the pressure would go from two bars to one, or half, so the volume would double.

But any deeper, the ratio of pressure between the current depth and ten meters shallower isn't double, it's n/(n - 1).

This is complete bullshit, I have first-hand experience with this.

They were all in plain clothes except for the single uniformed police officer.

There was no SWAT team (in my case).
