So many comments criticising someone who makes a splendid video with so much new material. You Tube videos are often quiet, I could hear this one perfectly well, are Americans all deaf, is that why they talk so loudly? The Oppenheimer film made so many omissions and the bizarre representation of Oppenheimer's supposed sexual proclivities was ridiculous. The contribution of British scientists such as John Cockroft, Patrick Blackett, William Penney and Geoffrey Taylor to the Manhattan Project was immense, particularly in the area of explosive lens design and the blast effects of the bomb, look up the references on Wikipedia. Blackett was the first person to deliberately transmute elements and went on to receive the Nobel prize for his work. And don't forget another area in which we were first, long before Chernobyl, with the reactor fire at Windscale, although the US tried with the deliberate runaway of the reactor at Hanford by a mad operator, and Three Mile Island achieved the first melt down, caused by the incompetence of the design. Leo Szilard is the often forgotten hero in all this, a Hungarian, he was the first to understand the concept of nuclear chain reactions and offered the idea of the atom bomb to the British Admiralty as he was legally obliged to do but they were not interested in it so he patented it himself and the rest is history, or at least a series of facts that historians choose to present in their own way. And in all these revelations we hear so little about the neutron initiators needed for plutonium bombs, I wonder why that is?

I know you are, but what am I?

I would suggest using a stirling engine instead. Thermocouples... Are kinda weak.

Oh good, 2142 isn't that far away!

Cher M Messier, I think I'll pass on the cypher solving. I admire those who can perform such mental gymnastics, but my brain just won't permit me to indulge successfully.

Might take a run at solving that cipher on the screen, but the short number of characters will make it a challenge. Unless someone has this cipher wheel lying around somewhere.

As a kid watching the lunar landings and EVAs, I had no idea that they were setting up all those experiments. Thanks!

The enigma looks like the automatic climate controls on an old Mercedes.

CoVid Time Stamp, y'all.

my minds in the gutter !!!

Ironic that the first Alexa is just as over complicated as the current one

Gabba gabba hey Gabba gabba hey Gabba gabba hey! Cool viddy!

Man, the Confederates really weren't all there, were they?

Both of my parents worked for Kodak in the 80s. I got an early model for Christmas. As a 10 year old boy who liked to experiment with things, I figured out a way to do multiple exposures on the discs. I did this on 3 or cartridges. When my father went to pick up the pictures from said discs, he got called into some manager's offices and was shown photos with 3 and 4 exposure shots. It almost caused a recall.

Yay new episode.

Do you have plans to do the German Enigma machine? Probably the single most fascinating and ingenious cryptographic machine in history.

VERY WELL RESEARCHED AND A HIGHLY COMPLICATED SUBJECT EXPLAINED IN LAYMANS TERMS.

Your intro was way way too long and a few seconds of sloppy buzzing code would make a nice intro, but a few seconds, a FEW seconds. The buzzing and QLF code went on way too long.

I read in a comment below that you are putting someone to sleep. Let me say that you speak very clearly and do not use the none word "um" thank you.

How about a double Vigenere encryption with keywords of lengths that are relative primes to each other?

"thermoelectric generator " why dont you just call it what it is and stop the sales talk. It's using a Peltier Module. If you need other sources of revenue that would be called "Get a job "

Some nice sharp jokes in there.

Jim, I love your videos in general. But half hour videos like this are also just fascinatingly good for taking a nap. I'll find myself starting it, napping away, waking up near the end, only to rewind it and continue napping. Your presentation and voice just has something really calming. So having 30+ minute videos like this one really scratches an itch for me, and I'll watch them multiple times which will also help your channel I suppose. Just wanted to let you know, love your content! ❤

I’m in my 30s, but I only ever saw one in the main office of my elementary school! It was the main phone they had at the entrance and it had a lot of labels with different numbers stuck to it. I think part of the reason they kept it well into the 2000s was because us kids had no idea how to use them, especially because we weren’t allowed to use it. Jokes on them, I finally learned how to use one from yt vids like this one!

The decoded messages read: Help! I'm trapped in a basement in Canada. The hostage-taker forces me to encrypt messages for him. I just escaped from the fortune cookie factory and now that! Please send help! And a peperoni pizza with extra cheese!

Well presented thank you 🙏

Human beings do not deserve this Earth....

😮

Gonna need a bigger shelf there bub

Etaoin Shrdlu is a good name for a DnD character

That series arrangement must've caused a LOT of headaches! Does the circuit remain closed when the telegraph is at-rest?

i love that you followed up name dropping the NSA with a vpn ad read, something that definitely wont protect you from the NSA

My father was a geologist and geophysicist who worked with Gene Shoemaker on the curriculum for teaching the Apollo astronauts geology. He was on the team that help spec the design for the original ALSEP. In my lap is a two inch thick binder dated August 30, 1964 titled, “Survey of Lunar Surface Measurements, Experiments, and Geologic Studies” prepared by the Science Services Division of TI for NASA. My father was one of the contributing authors. In an extremely oversimplified nutshell, on October 25, 1963, they wrote to 45 prominent lunar and space scientists and asked, “We’re going to the moon. What experiments do you want us to do when we get there? What will be the mass and size of the equipment and what constraints will the lunar environment and the fact that an astronaut in a bulky space suit has to install it place upon it?” Twenty-eight scientists responded, all from the end of October to end of November, 1963. Dr. Thomas Gold of Cornell wrote his reply on November 22, 1963. Obviously, he wrote it in the morning because Kennedy was assassinated around noon and the country spent the rest of the day glued to Cronkite. Considering that this was produced in 1964, I think they were as proud of the computer program they wrote to collate, score and weigh the various responses as they were of anything. Over a quarter of the report is devoted to that. This book is a treasured family heirloom.

Does anyone know the name of the music in the opening? I played this song years ago in an orchestra but can't remember the name

"advantage in technology squandered through laziness and incompetence" -oh boy that certainly doesn't describe many current administrations at all...

Im disappointed, that its not the host himself doing the pointy thing during the sponsory time. Moreover, how would a receiver actually read Sinclair's cipher? Thanks

Just a moment - frequency analysis have no use here. Each wheel has different substitution. Even if you know construction, and have large number of lines with the same setting (wheels order), each line was randomly chosen.

Of course the NSA has a great sense of humor. It's, essentially, a concentration of the nerdiest of the nerds and, as we all know, geek humor is the best.

I have this sudden uncontrollable urge to watch Dr. Strangelove tonight. 😊

Good read on this topic: The Code Book, by Simon Singh.

I always thought this was developed by the Mason's.

"The NSA Has a great sense of Humor, who knew?" I mean, they have possibly the geekiest job in the US government. I'd be more shocked if they didn't.

Such a fascinating compilation of explaining cyphers, codes, and the various ways they are used!

I can hardly work CW but I know some hams that have amazing skill. One I know has a leg mounted key he uses while driving down the highway on long trips. What’s amazing is he can be sending and receiving 20 wpm while talking to the passenger in his car with him.

Just to point out: ETAOIN SHRDLU is the first two columns of a Linotype keyboard. If a Linotype operator made a mistake in al line of text, they would run their fingers down those two columns to fill out the line of text and start a new one. Occasionally that block of text would accidently not be discarded and ETAOIN SHRDLU would end up in the printed text. Looking forward to your Linotype video 👀😅

Agree with Gettysburg tour and museum. It's really well presented! Dont miss it!

I'd love to see your videos on Odysee!
