I like listening to Fenyman on Physics, equally though, I like the stories he used to recount.

Feynman got a lot more enjoyment out of life than most people! 😘

Religion is a massive scam

🎉🎉🎉🎉🎉

What a gem!

Godbless Feynman , AND the human that filmed this , just to think if he never filmed this we wouldnt have it , people often forget how much of an effort filming was back then , cost of batteries , cost of tape , they were bulky etc etc

01:03 Computers are not primarily for computation but are data handlers, acting as advanced filing systems. The central part of a computer, known as the computer proper, processes data like a high-speed filing system. -Different types of computers exist, from those that receive data through talking or typing to those integrated with machinery like automobiles for automatic functions. -Computers function as data handlers, managing information from various sources like keyboards, sensors, and internal systems to produce outputs like controlling gasoline flow or displaying images. -The core of a computer, referred to as the computer proper, acts as a sophisticated filing system, processing data and performing tasks beyond traditional arithmetic computations. 08:14 The video discusses a filing system where file clerks handle information on cards by following specific instructions, such as picking up cards, performing calculations, and updating totals.

I get his criticism of Feynman’s ego, but Feynman didn’t actually advocate for not brushing your teeth on national television. He just wanted people to think about the things that they do perpetually without questioning them. Other than that, great video!

richard feynman is the only nobel prize winner who was also a black belt in Brazilian Ju Jitsu

43:40 if we become large then the air becomes less viscous right?

Excellent experiment

As a expert in nonlinear crystals, CRYSMIT offers high-quality BBO crystals.

huh? 😆

Paaaah! No way, you inmediately upload a new video. Thank you mr Muon

Hey guy, you inspired me a lot with this thing. I star searching and making progress turning LSC into art

CLASSIC!!!!!

Honestly and truly the best example that one can be joyful and friendly while wielding the greatest mind and hearth off all, Richard IS

if we learned anything, there is a ludicrous speed 😂

Great work keep continue keep growing❤

He's not right that "the ones shot out fastest are furthest from us". They all have pretty much the same local proper velocity. What makes them increase in velocity, with distance from us, is simply that space is expanding between us, and it. The more distance, the more velocity is imparted by uniform ubiquitous spatial expansion.

1:20 James Randi definitely fucked Richard Feynman.

Who am I to compare myself to Dirac, but I do not see the relevance of comparing the number of particles in the universe to the age of the universe.

Any experts out there who can shed light on any new thoughts or developments about these ideas?

5:33 The Gravitational and Coulomb constants don't have to be the only items changing.... could also be the charges and the masses?

3:57. what "atomic unit " of time is he talking about?

I remember cloud chamber experiments in grade school in the 1960s! Numerous demonstrations also occurred when I was in junior high school... the level of non-teaching via lack of! meaningful labs is terrible these days!!

I'm going to try to repost the comment I made in reply to yours under your subsequent video to this one on IR filters for phone cameras in hopes that it isn't 'dennabwodahs' here as well. "I'm just using the emitters for deep UV flashlights that I use to excite fluorescent minerals like willemite and the terlingua type calcite. I have a Yingfeng emitter, which as of a few months ago anyway was the highest power UVC LED available, and the ZWB3 cleans its emission of visible light nicely (not totally of course, but mostly). A ZWB2 will get you similar results for your purposes with even better visible blocking ability, but will admit somewhat less IR and almost no UVC. If you search for that specific part number you will find a post on another site I did with some traces of the emission spectra both filtered and unfiltered. If you search for the phrase "modified phone sterilizer emitting 280nm light" you can see some additional traces of ZWB3 filtered light from one of those Homedics phone sterilizers that became popular during early 91-DIVOC. It is the lowest expense source of pure UVC light I was ever able to find, and though not bright, is useful for philately and mineral shortwave fluorescence detection."

The future is now, my dear old Feynman. Wish you could see.

Aaaand of course my lengthy detailed comment reply to yours was autodeleted by the youtube artificial idiocy algorithm for who knows what reason this time. One may easily find one's self under the impression that this site's management is doing everything it can to simply destroy its user base and drive any and all intelligent content and its attendant commentary as far away as possible in favor of ever more base clickchasing trash. No more direct messaging either, so if your comment is memory-holed you're just s.o.l. Perfect setup, youtube.

You may wish to try a simple ZWB3 instead for around a fifth the cost and much less visible light contamination. We like them for using with deep ultraviolet AlN UVC LEDs to notch out the chip autofluorescence in the visible so as to give a purer light for illuminating fluorescent minerals. It will admit less IR overall in the longer wavelengths beyond around a micron, but so little of that is actually detected by the cmos of a phone camera anyway it doesn't really matter.

Reminds me of his books

And here I am again 2024 ! I guess I watched this doc at least 50 times and it’s still sudden….

Can I use this as a background for a song please ?

I am skeptical of all knowing scientist rock Stars

Watch and learn how to use emotions to emphasize something. Quite interestingly and sadly, most of the modern talks are just flat in this sense. As if those speakers weren't brave and smart enough to joke, etc.

Funny thing about being a skeptic… you get in the way of hucksters taking advantage of vulnerable people and YOU get labeled the bad guy

Can I ask for the design of your flexible module?

Sitting here on my 5nm architecture CPU watching this. Amazing.

yeah I'd have to watch this a hundred times to even know what's being discussed; yet i find it appealing

What about Integrated Photonics use of integrated photonic circuits, which can offer precise manipulation of light at a very small scale, potentially improving the control and measurement of quantum states.

Awesome work

Attosecond Laser-Induced Aneutronic Fusion Power propulsion Nuclear fusion occurs in massive stars with extreme temperatures and densities. These conditions can be briefly created on Earth by concentrating attosecond (1e-18) laser pulses on crystalline Lithium Hydride (LiH) at the bottom of the rocket. The resulting plasma contains lithium, helium ions, protons, and electrons. Pulsed alternating electric fields shape the charged particles and use magnetohydrodynamics (MHD) to directly generate electricity and provide thrust. MHD efficiency is more than 80%, compared with 40% for conventional energy conversion. A 1-attosecond pulse will penetrate 1 layer of atoms in that time, but the thermal (phonon) energy will only reach the next layer 20 femtoseconds later. The short pulse minimizes the heating and melting of the underlying material. Incorporating a cavity structure into the target material traps and slows the plasma dispersion and allows for longer interaction times, potentially leading to increased fusion reaction rates. Additionally, the cavity can reduce mass ablation, improve laser absorption, and facilitate better mixing and compression of the fuel material during the implosion phase, thus contributing to more efficient and effective fusion reactions. Cavity produced with additive manufacturing (AM) techniques minimizes variability and allows for the creation of complex structures. Alternating pulses of electric fields can be used to expel/attract negative particles or attract/expel positive particles at critical times during and after each laser pulse. The positive particles are effectively stationary when compared with the speed of the electrons in these time scales. The heavier positive particles, absorb more laser energy and contribute to increased fusion rates when their stay is prolonged. Expelling electrons from the plasma stabilizes the plasma, reduces losses due to electron recombination, and reduces the effect of Debye shielding. At an intensity of 1e-21 W/cm2, the first layer will receive most of the 1.2 MeV of energy per atom, equivalent to a temperature of 2.4 billion kelvin and velocity of 2.7e6 m/s for the heavier ions. The velocity of the electrons will be much faster due to their smaller mass. Nuclear Fusion reactions of Lithium and Hydrogen Proton + Lithium-7 = Beryllium-8 (4.42 MeV) = 2 alpha (18.16 MeV); total 22.58 MeV Proton + Lithium-6 = alpha + Helium-3 (4.27 MeV) Proton + Helium-3 = alpha (18.8 MeV) Helium-3 + Lithium-6 = 2 alpha + Proton (16.88 Mev) Helium-3 + Helium-3 = alpha + 2 Protons (12.859 MeV) Lithium Hydride must not be exposed to water. Fusion reactions have to be undertaken inside a vacuum. The laser repetition rate controls the output power level, ranging from zero to megahertz. Such a system can be adapted for Earth by converting the charged particles directly to electricity with MHD. The exhausted charged particles can heat molten salt, storing the energy for hydrogen production, synthetic fuel production, seawater desalination, district heating or cooling, powering ships equipped with thermoacoustic Stirling generators, and power plants with supercritical carbon dioxide turbines. With such abundant energy, a trip to the moon would take only 4 hours with an acceleration of 1 G. Similarly, a journey to Mars would require just 5 days, eliminating the need to wait for Earth-Mars alignment. A trip to Saturn will require 10 days. Back to the Future: Fusion Energy from Garbage Any solid waste material with a density lower than nickel can be used as fuel. These materials can be mixed with binding agents and compressed into fuel rods. Materials that produce charged particles are preferred. The lower the density, the better. Avoid using materials that can produce gamma rays, neutrons, or radioactive isotopes. Most thermonuclear weapons use lithium hydride (LiH) instead of pure hydrogen for fuel. LiH offers two advantages over pure hydrogen. Firstly, LiH is solid at room temperature, allowing easier storage without extreme pressure or cooling. Secondly, during the explosion, lithium atoms undergo nuclear fission, producing tritium (hydrogen-3), which enhances the fusion reaction. Lithium Hydride has a high Heat of Fusion of 2900 joules/gram, low thermal diffusivity of 1.2mm2/s, high melting point of 688oC, a molecular weight of 7.95 grams/mole, density of 0.757 grams/cm2, specific heat capacity of 6.27 j/g.k, and good electrical conductivity.

mr beast takes a dump and eats it... would get 100 million views... an absolute genious of our time gives the first real understanding i ever had of how ALL types of computers work... cant even crack a million views.... humanity deserves this spiral to hell we are in

He does show certain limitations in his logic - for instance, the question about anti-gravity - he said it is impossible because it doesn't fit the known laws of physics - he's wrong here, our world and the solar system is floating in an anti-gravity state and has been that way for billions of years.

I love this. He was so brilliant and innovative and yet so practical. A true physicist.

Those poor people thinking they were healed .. I hope God healed them anyways, but what an awful "trick" to be played on them. It's dangerous too, what if people stop going to doctors, stop taking their diabetes meds, that woman looked like she was going to fall without her walker. I actually did watch peter popoff a decade after this happened, though I can't recall sending him money, as I was maybe 17 and didn't really have money. I didn't know any of this had happened before, now I'm pretty surprised he came back from it... I know God and Jesus forgive, but I'm surprised the public did !

This is fabulous

This also explains why current A.I isn't intelligent. A.I is just large sets of data(files) being compared, correlated etc to form new Output. It doesn't fully understand what its doing but can compute large data hence it's not intelligent.

Brian Cox could talk about a glass of milk and I would listen to him.
