Discussion Overview

The discussion revolves around historical and technical aspects of significant machines and vehicles, including the ENIAC computer and the Russian Ekranoplan. Participants engage in a quiz-like format, posing questions and providing hints about various inventions, their specifications, and historical context.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant describes the ENIAC, detailing its size, weight, components, and power consumption, while noting its limited processing power compared to modern devices.
  • Another participant identifies the ENIAC as the machine described in the previous post.
  • Participants discuss a large vehicle that weighs 540 tons, can travel over land and water, and is hinted to be built in Russia, leading to speculation about its identity.
  • Some participants propose that the vehicle in question is the Russian Ekranoplan, explaining its design and operational principles related to ground effect.
  • There is a discussion about a vehicle that achieved over 188 miles per gallon, with participants speculating on its type and historical significance, including a mention of a Harley Davidson motorcycle from 1908.
  • One participant describes a crude device involving a wooden stand, a funnel, acid, and copper wire, prompting further questions about its purpose.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the identity of some machines, particularly the vehicle that achieved high fuel efficiency, as various guesses and clarifications are made. The discussion remains unresolved regarding the specifics of some inventions and their historical context.

Contextual Notes

Participants express uncertainty about the specifications and classifications of the vehicles discussed, particularly regarding the Ekranoplan's operational capabilities and the fuel efficiency claims of the motorcycle.

Who May Find This Useful

Individuals interested in the history of computing, engineering innovations, and the evolution of vehicle technology may find this discussion engaging.

My other hint was going to be: "he got first prize"

That is, Roentgen was the recipient of the first Nobel prize in Physics.

Although "photograph" is a technically correct answer, as I tell my students, you did not read my mind, therefore you are wrong!
I just figured out what this bizarre utterance meant.

Don't feel bad zoob, I had a typo on 93.999999=1 ( I meant 93.999999=94). Integral pointed out my mistake, in a way apparently much too vague for this old brain, and I didn't figure out what I had typed wrong until the next morning. :redface:

BTW, how many of these precious FREE kittens that a stray cat just had at my house should I send you? :biggrin:

A what was it revival?

This made quite a splash in 1979.
 
  • #249
Uh oh! That was a bad clue.

...and those down under would know!

What was Skylab 1 ?
 
  • #251
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.

A slight deviation from the beaten path, if I may ...

What is this ?

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:

Zooby, Danger, next? Or Gokul could try another one...

4*10^19 variations

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

Noooope... but the math is probably close.

The game of chess, then?

The game of Life?

Poker?

Wait, maybe it's not a game?
 
  • #262
21! is close (5*10^19) but not close enough...anyway, I don't know anything that comes in 21 sizes/flavors/colors/etc.

Ooh nice guess ! Also, aren't there like only 20-odd different amino acids ? ...but protein lengths aren't limited, are they ?

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.

Wild guess based on the same clue: An abacus?
 
  • #268
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.
