"You can just edit this, can't you?"
"Yeah, yeah...(but not the way you think we will)"
TROLL!!! Troll behind the camera! Just thought everyone should know....
I liked your joke, rom
@Kingston Boden Suddenly all my top comments get this obviously fake dialogue. Here's another pro tip : ban flixzone!
@@DrDress That's a standard trope of video making nowadays.
I went directly looking for this comment 😅😂😂
I would like to add that Planck's constant is "h" because he called it "Hilfskonstante" which means "helping constant" in german. So basically h stands for help when planck didn't know how to name it yet.
Emmanuel Mayuka The term you're looking for is "auxiliary", not "help".
Emmamuel is remarkable!
@@asully3006 LIGO is remarkable!
@@Nyocurio My dictionary says "auxiliary" means "helping."
Quantum Entangled Twisted Tubules:
When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else. It must be something else. Therefore, a "particle" is actually a structure which stores spatial curvature.
"You can just edit this can't you?"
"Yeah-yeah-yeah"
*Doesn't edit*
"You can edit this out right?" "Yeah!" And then he leaves it in... that really cracked me up.
I don't see the problem. He asked the wrong question. He should have asked "You will edit this out right?"
Ronald de Rooij The problem? Let's see... ahhh yes, the problem is they didn't negotiate a suitable compensation, like... "If I give you my first born, will you make me seem perfect in the eyes of the unwashed masses?"
doceigen Like, "you can edit this out, right", and hands over 50$.
doceigen :-)
Prof. Moriarty: "You can just edit this out, can't you?"
Brady: "Yeah, yeah, yeah"
People like you spending your time for the education of other people who wants to learn , are making world a better place
h, pixel size for the universe!
You know I kinda like that analogy!
hah, I like that. Might be useful in explaining it to laymen. If the pixels are small enough, you see a continuous image. Of course pixels don't have wave like characteristics ;)
OK, so pixels as we know them are 2 dimensional, so that would be h-squared, and 3d holographic pixels would be h-cubed. I like the idea.
h = hogwash
hah from someone who's been watching this channel for years, its fun to go back to these and see how young the professors look
I wish some of these videos were longer. This one seemed to be just getting started. It would be fantastic to explore some more of the detail.
Sixty Symbols videos are one of the most timeless videos on CZcams.
Look up Bohr's postulates of the atomic model, I believe. Electrons can only have certain discrete orbits, thus electrons transitioning between different energy levels (orbits) would emit photons of specific frequencies only.
I love that he leaves in the bits where the lecturers say 'just edit this out'
Yeh yeh yeh yeh.
haha, banter!
1:36 "why it's called 'HAITCH'"
DAT ACCENT ♥
I would LOVE to hear more about the effects of a larger plancks constant!
the man at 0:43 is by far my favorite scholar in your videos. i just love the way he talks.
03:33 you can just edit this can't you? yeh yeh yeh (Not really lol)

I have to have to greatest amount of respect for such an intelligent person that admits, and dares to utter the words "i dont know". I´d much rather listen to a person that can say those three words than one that can´t.
"Discrete values..." So can Planck's constant be looked at as a hint of the "pixelation" if the universe is a simulation?
I am not an expert, but that makes sense to me! Nice analogy.
gives us a nice "cinematic" 24fps
to a certain extent, yes
same as Planck's length, which is the true resolution of the universe.
Edit: If everything is qunatizized
I once asked this exact question to a physicist. He told me that position is not only uncertain but also non-discretized. It can have any value, not specific allowed values like energy. At least this is what we currently know. There are theories that give different meaning to the Planck length and space might be quantized and we might be living in a simulation. But we don't really know.
thanks sixtysymbols for posting up all these amazing videos.
Camera is too close to the face in these interviews. Planks Constant is hard enough to deal with without it being "in your face".
I love these lectures. Understand them, no. Ain't got the math.
+Colly Leslie Just realizing that humble fact makes you smarter than most.
+Colly Leslie Glad i'm not the only one :')
Mohamed Loumine I can not imagine how Planck determined the values for his constant.
Me neither i hope i Will Pick something up atleast on a subconscious level
***** I'd agree that's true in principle, but physics has advanced far beyond anything in our (and Michael Faraday's) experience. The low-hanging fruit of discovery is very probably gone, and without math it's hard to see how anyone could add anything to physics at this stage.
I'd love to be proven wrong though :-)
I want to trip on acid and pretend planks constant is 1 and diffract :D
man, you deserve a cookie
On the Planck scale, Planck's constant is equal to 1.
NICE IDEA! ANNNND i JUST HAPPEN TO HAVE A FEW HITS OF YUMMY 1P-LSD :) :)
@carlsontechnology-They are using E=h*nu
The photon hits the metal and is annihilated. The energy it possesses goes into 2 places.
The metal in the photo diode has a "work function" equal to its first ionization energy. This is the minimum amount of energy required to eject an electron.
The leftover energy is given as kinetic energy to the ejected electron. By determining the energy of the ejected electron plus the work function, you get the energy of the photon. Divide by nu to get h.
Action is a functional describing the dynamics of a system. It has units of energy*time (usually joule*second) and the system evolves such that its action is minimized (or more correctly stationary). It is basically just a way to rewrite a problem so you can solve it as an integral instead of a differential equation.
Sixty Symbols great video, but i would like if you went more into detail as to how the value was actually calculated and also why it's measured in Js, i think more people would keep up than you might expect.
in saying all this, it's very interesting to think that the universe has a discrete resolution. keep up the cool videos :)
Mr Tompkins was just smoking great kush.
Happy 156th birthday Max Planck
It surely was confusing. But what he pretty much means from 3:50 - 4:00 is that they're using the formula hf = W to measure out "h". Where "f" is the frequency(The green light) and "W" is the energy of the electrones.
I know it's wrong to think this, but as someone who works with digital audio I can't help but think of the Planck length as "the samplerate of the universe".
I'm with you, but sample rate is a frequency, as you know. So maybe sample length? Oh but that brings time in again. Tricky...
SquareWaveHeaven I think of it as the Universe's pixels, I guess samples are the audio equivalent of pixels.
+SquareWaveHeaven Space! Time! All the same. Digital is a special case of analog ... until you get to the smallest scale. There, analog is a filtered version of a quantum (digital) universe.
***** I am minded of the Kinks ... dedicated follower of fashion... Current orthodoxy has it that everything, at root is discrete ( or digital or quantised, pick a word ). How long must I wait for a digital expansion of pi ? Forever if that old greek was right - it's irrational and cannot be expressed in digits. Maybe he was wrong, but for the time being mathematics would be severely incomplete if such essentially analogue concepts were excluded. The effects of tiny errors exploding in chaos theory are a warning sign! OK, most current physicists would agree with you that we experience a smoothed out version of a fundamentally step-wise reality. But maybe it's the other way round and Berty Onestone was right with his analogue fields.
+Ray Kent Or, as Terry pratchett once stated it: The universe is created and destroyed all the time, hopping from one discrete moment to the other in planck time steps.
Each Universe only exists for a planck time moment. Isn't it a miracle that the next universe is nearly the same as the old one, and we perceive it as an ongoing thing?
I know that the "color bands" could be substituted into certain formula to find out Planck's constant.
For example, for a hydrogen emission spectrum, the frequencies observed could be substituted into the Rydberg formula (for Balmer series). The Rydberg constant could be obtained, which could in turn obtain the Planck constant.
I don't know the formula for mercury, but I suspect some adjusted form of Rydberg formula is used.
(I'm not that experienced, I just learnt this at school)
The furthering of knowledge is never a waste, as long as something is learned. We're not just building another particle accelerator. It's a stronger one, it will allow us to, hopefully, view things which we haven't been able to so far. There's the finding(hopefully) of the higgs boson, or at the least getting closer to it, the graviton( if it actually exists, and if it doesn't, maybe we'll find some fuller explanation of how gravity does work), and that's just the physics applications I know of.
im 18 days older than this video.. and i'm watching it because i was researching about the uncertainty principle and wondered what exactly h, plank's constant, was. crazy.
Veritasium brought me here! I didn't even know sixtysymbols made a video about Planck's constant; I don't know how I missed this.
if you think you understand quantum theory, you don't understand quantum theory
- Richard Feynman
I am also loving these videos, I have a deep passion for theoretical physics
Because I ask them to (because it shows up more easily on camera)
By the way, all the scribbles they do on and off camera are all kept and put on our Flickr account at sixtysymbols
Check them out!
The ratio of the Energy of a photon to the photon's frequency is equal to the Planck's constant. ie. E = hf. And if f is equal to the threshold frequency (ie. min frequency of light for it to have enough energy to eject an electron), then hf = ø, the work function, electrons would be emitted, and this is the photoelectric effect. hf = KEmax of electrons + ø.
This should have way more views than it does. Love your videos.
Professor with worrying/ashamed voice: 'Can just edit this, cant you?' Cameraman you reassuring/confident voice: 'Yeah, yeah, yeah'. Then proceeds to show the professor almost breaking the experiment.
Planck's constant is two constants, the product of a Magnetic Quantum M=Wb/2P and a Electric Quantum Charge q=4C/3kP. The product h=Mq= 2CWb/3kPP. The Quantums fill Space and define free Space impedance z=M/q=375 Wb/C=375 Ohm!
The Universe is Electric, the charge is 4C/3X=25e/3=(13U1d) Quark and Magnetic field is M=Wb/2P = Br^2 and
B=zD=uH=E/c. Wb=Voltsecond=Vs.
anyone who is not shocked by quantum theory has not understood it
-Niels Bohr
=) loving these videos!
Yes it is a constant just like c is and it is defined the same way. C is not defined by being 3x10^8 m/s or whatever, its self defining because its the speed light is traveling. It doesn't care what units you are using or anything like that, the light still moves at the same speed. Similarly h is self defining by being the smallest interval of action. The energies of photons come in discreet values. The size of the gap between these values defines h regardless of what units you use.
Ehrm, I missed the part where they actually calculated Planck's constant.. He said they did it by looking at the energy of the electrons that came off that piece of metal but nothing more was said..
I think, they multiplied the energy with the frequency to get h.
@@nickduckduck6990 divided
@@hakanhallin3800 Yeah right, divided. Thank you for correcting me.
Don't confuse the planck constant with the planck length, they're two different things.
From start of wiki on the Planck constant, it is the quantum of action (action is measured in J*s), and is also the quantum of angular momentum (give/take a dimensionless factor of 2pi). The units of ang. momentum are also J*s, ang. momentum = moment of inertia * ang. velocity = (kg * m^2) / s = (kg * m^2 / s^2)*s = J*s.
Why does J = kg * m^2 / s^2? Think kinetic energy: e=1/2mv^2 --> J = kg * m^2 / s^2
I read that c comes from the Latin word 'celeritas' which means fast and originated with Faraday or Maxwell or one of that ilk.
The constant is anthropocentric by its very nature - and relates to light - or the accuracy by which the physical phenomenon of light can be perceived by human vision. The question is not if nature is quantized by the quants of Planck, but that the observer (human) is limited in his/her accuracy by which to perceive nature in a PHYSICAL SCALE - a scale that intimately relates to the scale of human PHYSICAL SENSES (vision among others). How Planck figured this "accuracy" out is a mystery.
Yes, he's talked about it before. Basically he keeps it because it was given to him and it has nice beautiful pictures on.
I understand him. I myself have some creationist books and they tend to be very well illustrated, maybe to compensate the lack of scientific content.
This is what I like about these channels, unlike the majority of CZcams, the viewers here seem much more mature and rational. Keep being awesome. :D
a property of waves is when they pass through a gap they diffract. Like he said if we had wave like characteristics (which we would under the proposed regime of quantum mechanics) then we would exhibit the same properties as wave i.e. diffraction
M also stands for Magnitude, which is one of the constituents on Momentum. Magnitude and Vector.
It was, however, we cannot describe anything (Using our current theories) when the universe was smaller than a planck length. That is one of the main reasons why physicists are looking for what they call the a quantum theory of gravity combining the ideas of quantum mechanics and relativistic gravity.
Imagination, making sure you truly have the concept down as to what is going on, critically thinking about how this one aspect effects others. There's lots of reasons, besides the fact that it's just fun to imagine "What if. . .?". Surprisingly, even scientists are fun-loving people, and not serious 24/7.
Ooh you have got to do a sequel to this more-than-a-decade-old video about ”what would happen if Planck's constant was larger!!
M is common for Mass, And in one Theorem, you have momentum equals mass times velocity, or P=MV. It's a common equation, so you sorta can't make it M=MV. That'd just confuse people. Good question though.
Smallest video possible, a Planck video!
Ooh cool, I'll be heading straight over to wikipedia in the morning then :) Thanks, this kind of contact with people so knowledgeable in the field of physics is so valuable to those of us with curious (and over active) minds.
Yours,
Josh
There's other things as well. Because the CERN is trying to do these experiments as efficiently as possible, engineers will be forced to try and think of how to scale it down without losing power, which could benefit us. Because this thing drains so much power( it's part of the reason for the prolonged downtime this time), people in the areas around CERN will probably be trying to figure out how to get more power, or use the power they have better. Knowledge is still the biggest for me though.
I love Professor Moriarty's glasses :>
3:34 - "You can just edit this, can't you?" "Yeah, yeah, yeah..." You guys crack me up.
Or, rather than thinking of anyone with a differing opinion from the tested and established dominant scientific theory as an enemy, simply reading about everything and keeping an open mind no matter how silly it might seem.
Also challenging existing theories (as well as your own beliefs) will either reinforce them with new evidence or prove they're wrong and must be changed (like happened with the indivisibility of the atom, the creationism and earth being flat).
i havent watched the video yet, but im about to, i just wanted to ask 60 symbols a question. if, the closer you come to the speed of light = the slower time moves forward and presumably going exactly the same speed of light = time may stop... does that mean the speed of light is actually the speed of time and going faster than light/time would mean going backwards?
Nah. Moving faster than light would just mean you have more than infinite mass/energy. So I suppose not. You also wouldn't be able to view anything, as I imagine having eyes with infinite mass can't be too useful
It's now exactly defined as 6.62607015E-34 Js.
Yes, and the significance is that the kg is now derived from h rather than by reference to a physical object.
Sometimes I wish I took high school more seriously, had gone to MIT and instead of majoring in chemistry, I chose physics instead.
E = hf
h is a relation between the energy of a photon at a frequency f.
I guess that's what they were aiming at, as you can show that different frequencies (colours) of light are able to activate detectors and then other colours cannot.
Doesn't matter how bright you make the light, it's the frequency that determines specific effects. (see Photoelectric effect)
That's probably their angle, but yeah, they didn't explain it too well here to be honest.
I like to look at the world where planks constant is one and all other measurements go up from there. 🤗
English is not my native language and I can't grasp what they say at 2'16 : « Do you ##### him ? Oh yeah, I don't think there is a physisist alive, dead or to come that wouldn't ##### Plank. » Can someone fill the # for me ?
I really like that guys glasses frame
h stands for Hilfsgrösse, meaning something like helpsize, or the magnitude of help.
Could the Planck Constant represent a constant of action in the process we see and feel as time?
Based on two postulates:
1 The quantum w-particle function Ψ or probability function represents the forward passage of time itself with the future coming into existence photon by photon.
2 Is that quantum uncertainty ∆×∆p×≥h/4π that is formed by the w-function is the same uncertainty we have with any future event within our own ref-frame that we can interact with turning the possible into the actual!
@MusicalAndTall It's a mystery. He never told us how he wrote down that number. If you could find out, you could get a Nobel prize.
The waves would, but the particles will fly off in different directions like he described.
The final is mind blowing
@Schmoikel The best way to know thy enemy is to read his documentation. This is why I've always had problems with censorship of unpopular books. Mein Kampf being a huge example (banned in many countries, Holland and Germany for two, I believe). I've read it, and perhaps in the luxurious glow of hindsight it shows some extraordinary clues that could have been used against him rather easily. Limiting your reading to things you agree with is a good way of limiting yourself.
Yep! There was another video on it somewhere on the Sixty Symbols youtube channel.
Am I the only one who finds Phil's accent absolutely adorable?
Yes.
In order to find Planks constant using mercury, are you taking the initial equation (p=h/lambda) and solving for h (h=p*lambda)?
If so, how is the momentum measured and is the frequency a measurement of the color detected by the photo diode?
I don't get it why only know this channel has come to my mind
I watched this vid again just to hear Prof Moriarty say 33.
It's called an emission spectrum, I believe.
Oh! By the way, It is said [weasel words] that h is called "h" because it stands for Hilfsgrösse, which means "auxiliary variable" in German. Those of you who are familiar with Google know this by now. I've done no original research. Sorry :(
That book 'Atlas of creation' keeps popping up everywhere..
0:00 - 0:25 Damnit Moriarty I like the videos with you, I like your personality and you show great enthusiasm but please DO NOT use such a marker on such a paper, it is the worst sound one could hear next to a constant sine wave which repeats for 500 years.
It's like a baby seal barking! How could you hate that sound?
Being a wave sounds very inconvenient.
After you finish all the synbols, you should make videos about all the famous physicists, since you mention them so much.
Planck's Constant is the product of the Electric Quantum q=(13U1d)=25e/3=4C/3X and
The Magnetic Quantum
M=Wb/2P=Vs/2P.
The two Quantums are spread thru out the Universe. This gives the free space impedance
Z=M/q=Wb/2P.3X/4C=3kWb/8C
Z=375 Ohm
This is what's Planck's Constant!
Fine Structure Constant
Alpha=e^2/2q^2=(e/25e/3)^2/2
Alpha=(3/25)^2/2=9/2×625=7.2m
Alpha=7.2m=7.2/1000=1/139
Planck's constant is the best constant!
-The Physics Connection
Einstein used Planck's quantization to solve the work function problem, and describe photon energies themselves as quantized.
Planck used the constant to describe the quantization of vibrations in the walls of the black box, without any care to the photons. This solved the ultraviolet catastrophe.
Thanks for posting for all the youtubers too :)
this guys accent is freaking awesome!
Interesting video!
This is an invitation to see an artist theory on the physics of light and time!
This theory is based on two postulates
1. Is that the quantum wave particle function Ψ represents the forward passage of time ∆E ∆t ≥ h/2π itself
2. Is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the w- function is the same uncertainty we have with any future event that we can interact with turning the possible into the actual!
"Yeah yeah yeah..."
You say that as though it answers the question...
I know about the photoelectric effect, HOWEVER it doesn't answer WHY that specific band of emission from that SPECIFIC element can be used to acquire that constant....
The question isn't answer by simply naming an involved effect, but rather by describing the relationship between these two facts...
h wasn't derived it was constructed to patch the black body radiation problem. All that h is is a mathematical "trick" to get an equasion that always factors to infinity (aka wrong) to give a finite solution.
Well, no....The energy of the photons emerging from excited atoms is
given by e=hv, where h=Planck's constant and v=the frequency of the
photons in question...
so then you could be ina ll sorts of places at once!
Physics, in my opinion, is not as interesting as chemistry or biology, but it is still cool, and I thank you for taking the time to show people what things are all about.

plank length - the resolution of the Universe
2:13 nice to see that Gandhi finally found his calling as a quantum physicist.
He is asked "Do you rate Planck?" as in, I rate The Beatles as a great band, he, and all physicists rate Planck as one of the great ones.
These people are about to figure out how our simulation is programmed.
Of course, we all are, if we're enough fascinated in the deepest secrets of our Universe
yeah, it all comes back to how that specific frequency is used... and why...
I want to hear more about the diffracting physicists.
So, like... the floating point precision of the universe?
"tree"
The value of Plank’s constant is obviously very small but the measurements contain a relative high level of noise (deviation).
This could of course be due to the sensitivity in the setup of the measurement - or due to quantum uncertainties.
Is the reason for this deviation known?
And has anyone ever tested the hypothesis that _h_ Is affected by the expansion of the universe?
And if _h_ is dependant on the [space] part of [space]*[time], then could the noise be caused by gravitational waves that we know today exist. Or am I mistakenly assuming that planks length is related to h?
