Bible?
Thanks for the simplicity, I spent 2 days from my time without any results in other channel but here just 2 minutes I understand the principle of interferometre

I love these straight forward explanations of physics! Similar to the explanation of the special theory of relativity. Very cool (and nice work)! This is lecture room 26-100 right?(spent many a hour in the back right corner trying to keep up ;) )
There is something between the laser and the beam splitter. Why did you not identify it?
Half way through I understood the point of the experiment and shifted to the right in my seat.
could have added a velocity selector fairly easily to sharpen the peaks...??

He charged the tinsel so it has a positive charge before he used the plexiglass on it?
1:42 Wilsooooon!!!
Ohh at first I thought there was a force being generated from the throwing, causing the spinning on whatever they are sitting on
Обращаюсь к Вам с предложением на совместное изобретения ГИБРИД гироскопа из некруглых, ДВУХ катушек с новым типом оптического волокна с «полой сердцевиной из фотоно-замещенной вакуумной зоной или (NANF)», где - свет в каждом плече проходит по 48000 метров при этом, не превышает параметры 40/40/40 см., и вес - 4кг. Предприятия по выпуску "Волоконно-оптических гироскопов" может выпускать ГИБРИД гироскопы, для учебно практического применения в школах и высших учебных заведений. Эйнштейна мечтал измерить скорость поезда, самолёта - через опыт Майкельсона Морли 1881/2024 г., и только тогда, опыт будет выполнен больше чем 70%. Это возможно выполнить с помощью оптоволоконного ГИБРИД гироскопа. Вот исходя из выполненного более 70% опыта Майкельсона, возможно доказать постулаты: Свет - это упорядоченная вибрация гравитационных квантов и доминантные гравитационные поля корректируют скорость света в вакууме. (Мы, не ищем эфир, мы увидим работу квантов гравитации) В итоге увидите *теорию всего* в простом учебном устройстве и новую рулетку, чтобы измерить Вселенную.
I mean again. A funny name for something important. Oh, it's Lance law and that's it. You guys are so fuck*** stupid. I can't believe. Why nobody sees. There is a different force. A new force or the old one you forgot about? Yeah, arabellent for us. And rebellion force. Why people just? Repeating bitch*** without thinking about what's happened to you. Maybe you should look. How this really? Slow things down. What happened when you shoot it, put it in it. Will it stop? I made this test and it stops a bullet. Fuck*** because they're breaking it stands to square. Right from the get-go. Electric first start slow. You stupid fuck* and
ja sebst centrierend ist es auch noch
soll mal einen würfelmagnet eine kupfertafel runterrollen lassen der rollt überschlägt sich würde dabei ständig dipole wechsel na dämmerts das der falsch liegt mit seiner behauptung das der widerstand an der wand grösser ist als in der mitte nix mit elektromanetismus einfach nur nachgeplappert ohne eigengedanken
Beautiful effect Wave Indicates Light's Medium
This is such a clear and concise video. I love it
Expression for the final speed is : ((1024/45)*mg*a^4)/(e*gamma*mu*M^2)

So it simply spin away
this was excellent
18:54 The peaks don't get sharper as you turn up the magnetic field... How on earth could you conclude quantization of spin from this?
21:20 the beam IS spread symmetrically... Something goofy happened when they turned the b-field higher. It coupled back to the oven.
19:07 how do you know they are randomly oriented? Theres a big magnet in the middle of the room for the experiment
Omg they didn't shield the oven...
a great demo
Glad to see in the comments that I'm not the only one gawking at the needle mysteriously going up and down and finding that particular analog-driven invention equally interesting as the cesium atoms ablating somewhere and passing through a split, through a magnetic field and hitting a not further explained detector to make said needle move. It's just voltages and resistances fed into an amplifier, being driven by natural unseen forces that make meticulously set up matter function like an analog graph maker even more enigmatic in its function until one looks at the graphs and takes a few semesters in College/University to even know which courses to take to learn more about it. Our ancestors gave us the tools we took for granted.
Did they really need the labcoats?
What are the parameters of the magnet: weight and diameter, as well as what is the length of the copper tube, its internal and external diameter?
I don’t think there can be a conclusion made that spin is “quantum”. The rational given is that the axis or angular momentum will precess in the magnetic field and the angle of that will be based on the orientation when entering the magnetic field. The only issue with this is that the particle is charged. As the particle precesses, it should experience a force. Surely that force will eventually cause the particle to completely align with the magnetic field. This would also explain why measuring spin a second time from a different orientation will have a 50/50 chance of being spin aligned or anti-aligned.
This part is explained in the asymetric field, as explained at 20:00; if you increased the field you wouldnt increase the dieflection of the beam symmetrically, it would favor the stronger field of the two differenty inhomogenous fields, leaning on direction. However it doesnt do this, it either goes all left or all right, showing that there is a type of angular momentum which is being unaccounted for which has two values(two peaks) which is called spin. If they used a homogenous field where both magnets are the same strength and shape, I think you would have a very good point.
This is so amazing!
😮

I really wish Haidinger fringes were explained in this video; otherwise it is not at all obvious why do we get a circular interference pattern.
Always aim for where your target is *going to be* not at where they *are* 😂
Dualistic universe ~ matter anti matter. - + -
What causes the shape to be like that instead of just a dot?
I dont know if this channel is still used, but would it make a difference if they threw the ball straight up? So the person who should get the ball, just catch it out of the air when passing by?
Very cool! I have not seen this experiment in a long time. To be more exact, I only saw it once in an undergrad experimental physics class and that was almost half a century ago. Having said that, I have done lots of nuclear magnetic resonance as a student, which is kind of equivalent, except that it's being done in the time domain.
goofy ass physics
So, the effect is that if I throw a ball at a location where someone was, but is no longer, it’s called the whatever effect?
What's the name of that property? It only applies to metals or could replicate with other materials?
what would happen if we cut a chunk of the copper tube out? (in the falling direction)
한규쌤 잘생겼어요
so physics is basically fucking megic that we understand somewhat
I'll probably get hate for this comment but I really don't get what's so fascinating about an object going in the exact direction it was thrown...
Its always amazing, how much more clear and logical old videos are.
Incredibly cool video.
You made my day with the demonstration of the precession of the bar magnet on the air bearing, starting at 19:06 and particularly 20:32. This is a fantastic film and I wish I was shown these things when I learned about atomic spin and NMR the first time.
