In summary, the ENIAC was a massive machine weighing 30 tons, occupying 1,000 square feet of floor space, and containing over 70,000 resistors, 10,000 capacitors, 6,000 switches, and 18,000 vacuum tubes. It required 150 kilowatts of power to run, which was enough to light a small town. The final machine was less powerful than a $5 pocket calculator. The Russian Ekranoplan, also known as the Caspian Sea Monster, was a ground effect vehicle that could travel over 400 km/h and weighed 540 tons fully loaded. It was used as a high-speed military transport and could transport over 100 tonnes of cargo. The

The dates mean nothing to me, but I was thinking of the time-dependent version Schrodinger's wave equation.


That was the effect. This preceeded Schrodinger's famous paper.

Edit: To say that was the effect is not really accurate. I should have said that his paper followed. A direct cause and effect determination is not possible. But many suspect...

I'm afraid that's it for me, then. I don't know much QM, and even less of the history surrounding it. :frown:

I was thinking along the lines of the frequency modulation in radio waves..lol so I must be wayyyy off.

No.

Okay, I came up with an abstract clue:

In the sense of this "what was it", in order to see how we got the cat, you first have to think like a dog.

Whatever you do (Ivan), don't give the answer away. I'm going to give this a serious shot when
I'm freer, if it's still alive then.

Okay. This is a good one. I'll hold out for a correct answer.

No, not butt-sniffing waves, but I almost used that one! :biggrin:

I have to leave for a while, so here are all of the clues given for my question thus far.

This may have contributed fundamentally to the evolution of Quantum Mechanics. We will never know for sure to what extent this is true, but it does seem that the cat is out of the bag.

Keywords:
Coupled
time-dependence
Snow
Wave
Brrrrrrrrr...
Bed
Inspiration
Alps
Christmas and New Year's, 1925-26.
Couple

Erwin Schrodinger, one of the greatest physicists of the twentieth century, used sexual activity as an arousal device for inventing "thought experiments." Schrodinger took his mistress and ascended into the Alps over Christmas and New Year's, 1925-26, to think about a wave equation for matter and, reputedly, to spend all his time in bed. When he descended again in early January, he had developed wave mechanics, which, together with Werner Heisenberg's matrix mechanics, became the foundation of modern quantum theory. Schrodinger's paper on this subject is the most cited scientific paper of the twentieth century. He had apparently combined the physiological with emotional, and harnessed a brainstorm of heightened awareness. Schrodinger also wrote a book called What is Life?, a speculation on the physical basis of biology that is widely regarded among scientists as one of the most influential books of the century.

A coupled couple. :biggrin: And I'll bet you were thinking of regular ole coupled oscillators.

Leon Lederman of Fermilab talks about this in one of The Discovery Channel science programs.

Is that a clue or an obscure answer? If a clue, the only thing that I can think of is a 'Jet Axe' (I think that's the brand name). It uses a high-explosive shaped charge to blast a water jet for cutting walls and such-like where straight explosives wouldn't be safe. Mostly used by fire rescue squads.

You are totally wrong, Danger; it is a reference to the place name Soggy Hatchet, a hill-billy town in Arkansas.

Dang! I knew that I shouldn't have slept so much during Geography class.
