Visualization of tensors - part 2A
zhlédnutí 34KPřed 7 měsíci
In this video we visualize the electromagnetic tensor. In Part 2A we use it to represent magnetic fields. Part 2B extends it to electric fields as well. Part 3 will dig deeper into the mathematical definitions, and show more example for physics.

This video visualizes tensors. It shows some introduction to tensor theory and demonstrates it with the Cauchy stress tensor. Future parts of this series will show more theory and more examples. It talks about the term 'tensor' as used in physics and math. In the field of AI the term 'tensor' was borrowed with a simplified meaning. In AI it simply means a multi-dimensional array. So for example...
Visualization of Einstein's special relativity [HD]

This is a remake of my video from 2008, rendered in HD, with narration and minor changes. This video demonstrates the effects of Einstein's special relativity on objects that move at high velocities due to the Lorentz transformation. The Lorentz transformation was already known a few years before relativity, but mostly in attempts to justify the classical conception of Ether and absolute space....
Shell sort vs Insertion sort

Introduction of Shell sort, and a match with Insertion Sort. For an introduction of Insertion sort, see: czcams.com/video/TZRWRjq2CAg/video.html Choosing the sequence 9-6-1: For a list of size 10, the gaps can be any number 1,2,....,9, and the sequence must end with 1. So each of the gaps 2,3,...,9 can be included in the sequence, or not included. So there's a total of 2^8=256 possible gap sequ...
Gamification of Bell's Theorem

This video shows a gamified version of Bell's Theorem called the "CHSH Game". The theorem proves the non-local nature of quantum physics, known sometimes as "Spooky action at a distance". The gamified version further shows that quantum entanglement can be useful.

It could always be worse... Miracle sort is a sorting algorithm where you check if the list is already in order, wait to allow time to pray for a miracle, and then check again until it is.
Hello author, I've recently been working on a mathematical physics chronicles content and I very much need to edit 5 seconds of footage using the footage from the video you created, I really, really need the 5 seconds of material. I'll be sure to credit the source of the footage and @ your channel when I'm done with my work. I very much recognize your work and thanks again. : ) (The above text was translated by me, using a translation program, so please forgive me if I use the wrong words)😀

They will never form a square of any size except for the original one, as they clearly can’t form a smaller square and if they could form a bigger one then they would also be able to form a smaller one
amazing videos. how do you make them? which software do you use?

Hi, Thank you for making this great effort. Unselfish and straightforward video. ❤
There is a fun way to make bogo worse. Simply save each previously attempted combination and first check if you have already tried that combo, before checking if its ordered. That way you waste even more time and also get rid of the constant space complexity, which is really the only thing bogo has going for it. You can also use a seeded randomizer and simply remember the seed when bogoing to reduce wasted space. However, you do need to use bogo to sort the list of seeds so you can use binary search to check if you've already tried that seed before. Ya know, so its efficient.

The explain is so brief and clear, thanks so much.
This is wrong! I'm leaving this comment here for people who will be here for 30,40 years when this theory will be disproven. They will look at this and say, good, some people already knew that this was wrong!
There should be a udiprod video of 3Blue1Brown vs udiprod, which one is better at teaching linear algebra.
Finally, two with opponents. Their battle will be legendary!
With all due respect, is this a video that can deny the omnipotence of artificial intelligence?
Well, what do you mean by omnipotence? AI won’t be able to solve undecidable problems, but neither can humans.
After gaining a bit of background on Bell's Theorem, this finally clicked for me. Well done!
So you understand why it's intellectual nonsense now? ;-)
@@lepidoptera9337 Possibly,but not for reason you think
@@a2sbestos768 I didn't think that you can reason about this. That would require some serous training in physics. ;-)
I think at 15:08 you incorrectly state the XZ plane for B-field, I think you meant YZ
A different explanation: the parity of each coordinate of each spider is invariant. But it is different for the smaller and the larger squares.
It's been almost 11 years and people still don't understand proof by contradiction.

After watching bogo for so long i was starting to think the joke is the rest of the video was just it sorting randomly I was correct
the funny thing is that's a better-than-average sorting time
Just don't use N and P, duhhhh (please reply to me Chaumas I love you)
H would forever compute the out put ,essentially a soft lock
That’s the same as saying H would get stuck. But H is defined as always giving the right answer, so if it gets stuck instead, that’s a contradiction.
@@chaumasYou're dedicated. I swear I've seen you here over a year ago.
For shuffling I was always using any old sorting algorithm with clear finish, mostly mergesort, feeding it random comparator function
Bogosort got that drip with the hat
This makes me wonder... what *are* the comparisons? How do those happen?
it’s so over stoogecels
I know bogosort was created as a sort of mathematical joke, but in execution it feels downright psychotic. If algorithms were people bogosort is a serial killer.
Which software are you using for vectors representation
I'm using Maya.
@@udiprod thanks for your response Maya is free or paid software
It's paid.
Came here to watch bogo sort succeeding Ended up with the knowledge of how to shuffle things properly
1
Plot twist: H knows how N would act, so it does the opposite of what the answer is
Then it would contradict its definition.
Yeah I get that, its only a joke
there’s a 1 in 720 chance per trial that bogosort works for 6 balls
This is dumb ah hell it’s like if you smashed x with a hammer and said “well h said it was gonna work so h can’t exist.” Machines exist with the input they’re given they can make estimates, not predict the future. Bro put a cookie in his ps2 and got mad it won’t run.
It is not at all like that, no.
the point of creating X is to show that H cannot solve every problem, thus it cannot exist.
Это прекрасно ! Спасибо
Humans can't walk on broken legs. Does that prove that it's impossible for humans to exist?
The definition of “human” does not include “able to walk on broken legs,” so no. But the definition of H _does_ include “always able to correctly tell if a machine halts on a given input”.
@@chaumasNuh uh
@@chaumas This is why cleaning products only say they kill 99.9% of bacteria. I they didn't say that, pedantic morons like you would come out of the woodwork with a never ending stream of bothersome nitpicks.
what exactly do you think is the problem with the proof
@@charliehiggins7876 This is a mathematical proof. If you don’t like precision, I recommend a different subject.
3:41 Why doesn't quick sort just pick the middle one on eachi.e a version of binary search adapted to sorting
Assuming the input is random, it doesn't help to pick the middle one. Consider for example the input 3,5,1,2,4. The middle element 1 is not a good pivot. The best pivot is 3, which happens to be first in this example. See a discussion here about different options for choosing the pivot: en.wikipedia.org/wiki/Quicksort#Choice_of_pivot
just check back later to see if its sorted itself, no need for fancy algorythms
Can you do miracle sort next?
"uhhhh, I think I'll go with... false!" - Wheatley
solution: make the h stuck if the blueprint contains itself
There are two problems with that. The first is that H, by definition, always gives the correct answer. It can’t do that if it gets stuck. So if a machine gets stuck in any situation, it is, by definition, not H. The second problem is that we can slightly modify X to use a machine which is _equivalent_ to H, but which has a different blueprint. For any machine, you can find infinitely many equivalent machines that have different blueprints. For example, suppose H contains some logic somewhere like “if A and B”. We can change that to “if not (not A or not B)”, without changing the behavior of the machine. You might next think “ok, then have H detect if the blueprint is equivalent to itself”. This, it turns out, is impossible. To do that, you have to solve the halting problem, which is exactly the thing we were trying to do in the first place. So essentially, we’d be saying “to solve the halting problem, first solve the halting problem…”
