Interesting to learn about the cryotron and its role in early computing. With advancements in both superconductors and silicon, how do you see the future of these technologies evolving in parallel?
Back in 1978, I was studying physics in High School. Our teacher brought a group of us to a lecture by a team from IBM. They talked about Josephson Junction and how that was the future of computers. Throughout high school, college, and into my engineering career, I waited for superconducting supercomputers. I followed the superconducting engineering news and the tiny breakthroughs. The idea of high-temperature superconductors was brought up as another source for the magical machines. It's been 46 years since my introduction to "the future," and I am still waiting. Thank you for the information and the memories from the past.
@17:30 That’s wild, I hadn’t thought about that song in forever, but I just heard it in a bar a few days ago, and then it shows up here. What a classic.
Baffling, how did anyone not easily see from the beginning that a computer that needed to be submerged in a liquid helium would never achieve mass adoption?
Such heroes! Still there are statues and memorials to lenin, dzerschinsky and yeltsin center in russia. Worst mass murderers of russian people only that remains missing is statue to hitler.
I have 3 unused mechanical drive and 8 SSDs. 4 installed as boot discs and 4 USB SSDs. I also found a file cabinet drawer full of 5" floppy discs! Trash anyone?
I am not sure that the NSA was financing specifically for cryptographic purposes. The NSA is financing mathematical stuff that have to be: * Not cryptography. They are the expert in crypto, not the people they finance. * Have potential application, however distant, to their work. So fine for combinatorics, but not for differential geometry.
The reciprocal of nowhere in now-connection is everywhere-when, Eternity-now and self-defines the trivial non sense of non location superposition logic, but every one must locate their own unique POV in functional correlations with uniqueness, ie argued with in alignment, not against necessarily in conflict where possible.
Teacher techniques taught to teachers, demonstrating student attention in the Actuality of logarithmic QM-TIME Completeness Conformal "resonance" fields = entangled shaping of the 0-1-2-ness vector-value, => e-Pi-i sync-duration connectivity @.dt zero-infinity instantaneous trancendental i-reflection containment Function "throughout the universe" by reciprocation-recirculation potential positioning. WYSIWYG here-now-forever, if you just look at it, learning by doing, self-defining re-cognition occurs in the sequence you might expect from Piaget's Stages, open POV, line-of-sight to linear experience, and holistic memory associations in "resonance".

Here in Scotland the word dram is usually used to describe a small glass of whiskey, and DRAM (pronounced Dee RAM) is a form of memory. One of those things will increase your memory, while the other will likely decrease it.
@@kyriosity-at-githubthat’s kind of the point tho. No one was ever looking at quantum computing for consumer applications. It can do calculations very well that standard PC’s can’t. So yes while specific it will still have its uses for for science. Just not for yourselves. Doesn’t mean it’s going nowhere.
Swords were always more status symbol. Just like being good sword duelist was status symbol. In wars on big battlefields there was many other much more useful weapons.
I think this was an informative video, but at 7:57 , I think you switched Voltage and Current in the shown Graph. I think the Current should spike at around 0V , taper of to the current density and then should slowly rise again with higher Voltage.
Look at the Isake diode. Discovered in 1957. It uses tunneling at room temperature. Its speed power product is 100,000 times better than CMOS. It is trivial to make Threshold Logic Gates using tunnel diodes, reducing the gate count by about 30%. Resonant Tunnel Diode circuits today run at 33 THz with 5 W. One problem is the hyper abrupt junctions requiring tolerances of 5 atoms. I used them in 1968 but none of our test equipment was fast enough to measure the circuit's behaviour.
I believe you have an error regarding Dennard's law. You need about the same electric field for the switch to work, but that field should be proportional to the voltage divided by the separation between electrical contacts on the transistor. A smaller transistor requires a smaller voltage to keep the same ratio, and therefore less power to operate if the amount of current flowing is the same.
IBM is the symbol of failure......anything successful project they made in recent 30 years? I think every direction that IBM made was wrong in the past decades, nothing success.....never believe that IBM can do anything right
One reason IBM's computer failed is when you cool the repairman down to cryogenic temperatures, they are unable to make repairs. The thermal stresses of warming and then cooling the circuits usually destroy them.
