As one narrator put it, "You don't 'mone fast and break things,' if the thing you're going to break has YOU INSIDE IT."

Awesome vid !

The rocket engine from hell

That training video 😢 Reminds me of the sex offender shuffle 😂

Wow, what a well put together video/documentary! It's amazing how far we have come in gaming/graphics technology. My kids love playing some of the retro games, and "retro-styled" games, and have asked me why I don't like them as much as they do. I try and try to explain, that I grew up during all of this, through all of this. I played games on the TRS-80, even played Zaxxon with a tape drive on one of those old computers. I learned "basic" BASIC. I played the original King's Quest and so many other games from the mid 80's. And I have been shocked and thrilled with the advancements made through these decades. I treasure what's now possible, as it was what I had always dreamed of when I was a kid. There is no way in hell I'm going to go backwards and play a game that looks like it could have been played on an 8086 with 2MB of ram at EGA color (16 colors)....or something like that, I don't exactly remember the specs. I do know that we went from monochrome (1 color), to 4 colors (CGA), 16 (EGA), 256 (VGA), then onward to SVGA at....a whole lot more colors possible. I cannot describe for you how amazing it was to go from 4 colors to 256. Oh, and we only had the little PC speaker for sound. Some amazing things were done with those little things, but when the AdLib (I think it was called that) soundcard came out, oh man, it was nuts! Actual music and sound.... Just leaps and bounds people. It kindof sucks that we don't have the same level of increases in tech like we had a couple of decades ago. Feels like we are reaching the top or something. How far can you go until things just look.....real, right? We are there pretty much, or at least close enough. Sorry, for rambling on....just fun to remember. :)

Regarding crew escape. Why do you assume that your math matters? You fail to include any measure for the value of the astronauts lives🤷‍♂️

I don't think my jaw has dropped in horror this many times during a single video before. This is giving me pleasant memories of the Things I Won't Work With blog! Exotic chemistry is always crazy to hear about. That red exhaust plume is really thematic, I have to also say.

And Richard Feynman learned to play the bongos later in Brazil.

Stockton Rush wasn't stupid? He killed himself through bad decision making, failure to consider other possibilities, and arrogance. If that ain't stupid what is?

Excellent video but have to pick up on a little boo-boo at 21:44. Stacks are Last-In-First-Out (LIFO) not First-In-First-Out (FIFO)…that would be a queue.

2:26 the terminology you're probably looking for is "(relatively) massed produced, Turing complete processor and memory"

The 3d animation is absolutely incredible. It's very difficult to distinguish from reality with the main giveaways being a slight pixelation of the fog/condensation effects, lack of shaking of loose hoses, and the overall cleanliness of the workshop

The most important takeaway from this video is how poor our records of groundbreaking things even in recent history can be. There may be original photographs that exist of these tests and designs, sitting in some filing cabinet somewhere

Well Done!

The Submersible knows where it is because it knows where it isn't.

alexander the ok, can you do a video on a theoretical metallic hydrogen rocket engines?

18:23 After IFT4, It's looking more likely that SpaceX will reuse Raptors in the next year or two. They're producing them so inexpensively that at this point it doesn't make sense to reuse Raptors. Anyway, I'll take a fully and rapidly reusable, full flow, methyl-lox Raptor for $250,000, over a refurbished, fuel rich staged combustion, hydro-lox RS25 for $65,000,000. Everything is dependent on catching Superheavy and Starship.

That thing was a pile of junk

Fascinating video!

hello, so I've just found your channel and thought i would say hello and with this video being about things in my own childhood and carrier path it seemed right to hay hello here. my dad repaired BBCs in his TV repair shop and when my school retired them i was gifted one. great stuff and keep the great content coming.

I am fortunate enough to have played all 3 - Elite, Elite II and Elite dangerous. And all 3 of them were fantastic. But it still blows me away that I was playing Elite on a Speccy

"Can I Play Doom with It?" (what about Myst?)

OSHA: how dangerous is this gonna be? Engineers: Y E S 🤪

🪦

They didn’t inspect the epoxy for air bubbles. And the titanium dome will flex differently than carbon fiber creating strain on the seal

Falcon heavy max payload is 27000 kg but I guess you have to start somewhere. It seems to me the British space program is roughly where America was in the mid 60s and it's completely self inflicted.

The All-Time Winner of the Darwin Prize! (that's all)

When the aperture science music fits your project perfectly, it might be time to consider self-reflecting on just how fragile your existence is and whether the science t worth it xD

"accidents due to mechanical error are uncommon" mechanical guidelines that have been preventing accidents: am I a joke to you?

There is a 5 part docuseries on youtube called "nuclear secrets". I think its part 2 and 3 that made Oppenheimer unwatchable for me. I truelly dont understand decisions made..

You failed to mention the main reason to use it: that red plume looks fucking awesome.

It's surprising that that was (apparently) a parallel-architecture machine, instead of having a serial ALU acting directly on a bitstream from the disc (or drum in many computers of that era).

if a vehicle is built by man it can be tested by man Oceangate achilles heal was lack of money

One of the best videos I've seen in quite a while. And I watch a LOT of videos, on many subjects.

39:20 Just an aside: Any self-respecting Jew, observant or not, should be quite willing and prepared to argue with God, to the bitter end. I do so respect that. And I say that even as a Gentile. Or maybe because I'm a Gentile.

To this day, I do not understand why Feynman was put on a pedestal for dunking a piece of O-ring in a beaker of ice water. Wasn't everyone long since well aware that the putty got stiff a.f. at low temperatures? Just whom did he think he was talking to? The TV audience? Someone help me out here, gently as possible. I just. don't. get. it.

I'm really enjoying your videos. They are well researched and presented.

"lets have a positive chapter before we blow up another shuttle!" bold.

Great video Many thanks

Stocktham ignored safety warnings that Titan was getting weaker with every dive

IT was reported that Stocktam bought expired carbon fiber from Boeing

SpaceX isn't close to anything

What an amazing, well researched video. I've learnt so much and enjoyed the presentation so much. Hitting the Thanks button hardly seems enough. Thankyou.

That fluorine engine would be the same thing as attaching a disintegrator beam gun to a rocket pointing down and using the recoil as propulsion as you leave behind an utterly devastated landscape. This is the sort of bullshit that the Adeptus Mechanicus would say "hold on a minute, that's too much even for us."

Thrust vectoring is only a thing in Russia mostly because they still think that jets need to dogfight. In an era where Fox-3 (beyond horizon seeking missiles) exist

As a woman who somehow stumbled across this video--the F14 is pretty! :)

wow, ill tell ya what... BOP are far larger than I thought they were, I figured maybe 6 or 7 feet tall, tops...

Damn thing had an N64 control pad for steering lol!

Let's not kid ourselves. If they made the sub out of Flex Seal and Flex Tape, none of this shit would have happened

Saw the original video, clicked on it, saw this video and immediately switched over. Good on you for making an improved version
