Nuclear Engineer Reacts to Kurzgesagt: String Theory Explained - What is the True Nature of Reality?

[retrograde]

Dance of Science and Engineering. I love the way you elaborated that one. I felt your excitement and enthusiasm. ❤

These "KurzGesagt" videos are usually well-done and funny. There's a whole bunch of them. Wouldn't mind if you do a few more of them.

And you're up to 10k subs already. Excellent!

A point particle can have mass. Mass is believed to be conferred by interaction with the Higgs field, so size is irrelevant.

[kitcutting]

this is sort of hopeful in a sense. If nothing else, what we can take away from all this is that we don’t have to be complete to be useful

[funkizer]

Thanks for another great video. One request however: Could you balance the levels of your voice and the video you're commenting?

[AndrewMefford]

And what is not known or understood is generally feared. Feared more by some than others, that is for sure!

[DeamonSorrow]

10:44 and good accountant would ask "and how much you want it to be" XD

2+2=5 for certain large values of 2.

Unified Field Theory will never truly be achieved. Not because the current Einsteinian problems preventing us from completing it are impossible to solve, but because once we _do_ solve them, we'll find something else paradoxical or otherwise wrong about our understanding of the universe because of that new understanding.

The universe is an incredibly complex system of systems, and as you said, we don't _need_ to know absolutely everything about our current technologies to use them. Kurzgesagt even listed a couple things we've used our current understanding of quantum physics to create (Quantum Solvents, Hadron Therapy, and Maglev Trains.) Do we understand absolutely everything about them? Hell no. Do we still know they're possible? Clearly, we've built them from theory into a reality.

That's not to say we should stop searching for the answers to UFT, far from it. UFT is an ideal, and trying to get as close to that ideal as we can has, and will be, the driving force pushing us into the future.

10:46 I don't think an engineer would say that 2+2 *is* 5 (at least I wouldn't) but it's perfectly fine to say that 2+2 is less than 5 (or could say less than or equal).
So mathematician: 2+2 = 4
Engineer: 2+2 <= 5 (for safety margin cannot be more than)
Nuclear engineer: 2+2 < 1000 (for safety margin it is definitely less than)

IIRC, the discworld from Terry Pratchet rests upon the backs of 4 elephants who travel the vast cosmic infinity upon the back of a turtle. Idk if that's the reference, but it was my initial idea for it

Is it bad that when kurzgesagt said that when the scientists created a gravity particle, but when they added it to their theory all the maths broke down, my first thought was ‘I hope they had a backup of that theory’?

String Theory is a somewhat useful Fiction. I hear a lot of Physicists say it was a wast of time, and we just need to shut up and calculate. I think we missed something fundamental back when we had to make an answer fit with a hammer a LOT of experimental results. It works but there is something shady going on. But I don't have a 150+ IQ so what do I know.

OK so this didn't say anything at all about string theory as such. In a couple of sentences - a guy name Veneziano modeled nuclear forces by elastic bands connecting them. IOW it was a completely phenomenological model, and nowhere near as useful as the old liquid drop model (which is still useful because the accepted theory, quarks and gluons - OCD - is absolutely useless for calculating ANYTHING, even the magnetic moment of the neutron). Somehow this purely ad-hoc model got taken seriously as a fundamental picture of matter. There were a large number of very bad physicists loosed upon the world in the 70s and 80s and they beat the idea to death with 26 and then 10 dimensional spaces. That's enough said, the idea is a complete and utter failure, but one that will not go away because its supporters find it impossible to admit a mistake. My advisor at Tech was the guy who invented the modern black hole, and a world class physicist. I remember asking him about ST, which I had stumbled upon in my reading. "It's horseshit, don't waste a minute on it" was his response. I said that was my impression and that's the last I thought about it! :) He was SO right.

2:22 yeah, and human dairy is possible

[skellious]

I'm enjoying your videos but your audio balance is way off. the video is too quiet and you are too loud. It would be good if you could make the video louder and then have it auto-duck when you start talking or something. at the very least doing a levelling pass before uploading it would help

When will the next episode of Chernobyl be out.

What did the Proton say to the Electron?



Why are you always so Negative?
