AI Thread Summary
The discussion centers around two significant machines: the ENIAC, an early computer that was 10 feet tall, weighed 30 tons, and required 150 kilowatts of power, and the Russian Ekranoplan, a ground effect vehicle that could travel over 400 km/h and weighed 540 tons. The ENIAC utilized a vast number of electronic components but had less processing power than a modern pocket calculator. The Ekranoplan, developed by the Soviet Union, operates just above water using a shock wave principle, allowing it to travel over various terrains. The conversation also touches on trivia and historical facts about these machines, highlighting their unique engineering and capabilities. Overall, the thread showcases a blend of technical details and engaging quiz-like interactions.

Yerrrrrrr it! :biggrin:

On July 11, 1979, Skylab impacted the Earth surface. The debris dispersion area stretched from the Southeastern Indian Ocean across a sparsely populated section of Western Australia.

False-colour image of a shark waiting for a skydiver?


I dunno. Looks like stuff that I've seen from an atomic-force microscope, but no idea what it's a picture of.

Close enough (so was Zoob) ! And the sharks may appear in future samples.

This is an STM image of what is called a quantum corral (corral -> reef -> shark, etc.) The cyan peaks are Fe atoms deposited one at a time (using an STM tip) over a Cu matrix !

That's amazing! I was going to venture a guess but now I'm glad I didn't. :biggrin:

I know it's not much of a clue, but I don't expect anyone here to have trouble getting it.

Sort of...

Sorry I didn't respond until now; I've been asleep. Now I'm going to work, so you're on your own for a few hours.

Nope, and twice nope.
That was a short-lived work day. I got there and my co-worker showed up 5 minutes later. It turns out the shift change we did last week was supposed to be permanent, so I don't have to go for another 3 hours.

Well that answers one question, at least.

Rubik's Cube!

Ok, here's one. I'm new to this thread so forgive me if I do something bad...

Clue 1:
First devised in 1941, the final product was a cylinder weighing about 4200 kg. A lot of hard work went into its design, but one of the most ingenious factors enabling its use was an incredibly simple idea.

Wild guess based on date and weight: nuclear reactor?
 
  • #278
Nope.

Clue 2:
I had lunch today in a building named after its inventor.

It was developed in Surrey, tested in Derbyshire, and used in Germany.

The concept was brought about in order to get over a net.

Since brewnog seems so confident I will assume that he is correct?

It seems way too heavy, but could this be the bomb designed to bounce on water? IIRC, it was devised to take out a dam.

I kinda assumed I was correct too. It doesn't matter now, because...

Yes! Barnes Wallis' "Bouncing Bomb", as featured in the epic film "Dambusters!".

Very well done, I thought I was going to have to use Clue 3!

Incredibly heavy devices, but I suppose you do need rather a lot of RDX to take out an entire dam. They had to bounce to get over the anti-torpedo nets which had been fitted to the reservoirs. The bombing missions were incredibly precise and difficult, - the planes had to be flying at 250mph, 400 feet from the target, before dropping the bombs. The planes had to fly at an altitude of 60 feet, no mean feat for a massive 4-engined bomber.

The simple but ingenious idea I mentioned was to combat the aircrafts' altimeter's lack of resolution at such low altitudes. A pair of spotlamps was set up on the belly of the plane, such that they focussed to produce one beam on the reservoir surface at an altitude of 60 feet.

And I had lunch in Barnes Wallis building today. :smile:

Sorry I didn't get here until now. Yes, I was referring to the original cube.
I loved 'Dambusters'. The uncle of one of my friends was on that mission. The spotlight trick was pure genius.

Critical to the patent of 1884, this is only slightly more sophisticated than a spinning pie tin punched with holes.

Ten years too soon. :biggrin:

We are so close, and I just tried and easily found it based on three very simple clues already given.

Oh, wait, you said it has to have a U in it, then how about a thaumatrope?

I don't know that one. I don't think so...

another clue: camera
