How do we KNOW light is a wave?
Вставка
- Опубліковано 2 жов 2024
- We might not have unified electrodynamics until 1865, but we've known light was a wave since the original double-slit experiment in 1801. Let's talk about diffraction and wave interference.

For anyone trying to find the next video about how photons are also waves: ua-cam.com/video/iyN27R7UDnI/v-deo.html (When videos are older like this, it's almost impossible to find their follow-up videos.)
i sort by date published and watch them a bunch
How do we get single photon..🙄
Ocean waves with longer periods carry more energy and travel faster.
In contrast, light maintains a constant speed; the shorter the period, the more energy it exhibits during collapse.
Therefore, it cannot be described as a wave, but an alternative term may be utilized.
The ambiguïty of light and fotons and electrons bothers me..^>~ as if they create their own carrier like a train putting his own rails on the trail but at an incredible speed ! That's why i come up with that ocean, just beiing everywhere, nada travel, just the impuls racing through what ever medium... i'm maybe crazy, too 😊🍀🧡🌞👍👋FM
I love how he states something....then he asks himself a question we are all thinking, and then he answers it! So awesome!
Love the "Shush !" too, exactly when I was asking myself the question lol
Yes, _exactly_! He's good at anticipating follow-up questions and asking them in a non-patronizing way. He has great communication skills.
I also . .
Don’t be silly, that’s Question Clone.
Sign of a god teacher
best explanation of this experiment I've ever seen
Indeed. It's rich in details and it's clear to a level I didn't even think possible. Nick is the man for concise and precise explanations.
Also animation quality went up again.
@Johnny Doeboy the electromagnetic field is the does
as a byproduct of electromagnetic radiation
As for science being dumbed down Im pretty sure this show is for kids I mean he's a guy in a lab coat with a bat man shirt making youtube videos for free on the internet are you expecting to watch his video an then get a science degree?
@Johnny Doeboy you're just being semantic. No one thinks it's a wave like in the ocean
Steak Electron refers to a small wave in the electron field or a particle (particles are localized waves in the field).
Fields are basically plains of existence for waves. The waves are energy.
Fields do have their own energy called vacuum energy or zero-point energy.
This energy is always there and cannot be taken away. If you try to, the field will make a lower vacuum energy.
The vacuum energy is the baseline energy.
There will be a little uncertainty in the energy (and everything else) in the field.
Just a question but do the dump trucks move with the wave or do the dump trucks just go up and down?
Btw I get that the field is waving and causing the action.
Johnny Doeboy I get that you have a large emphasize on electrons aren’t hard balls but rather deformations of the electron field.
You don’t need to call me out for being a random guy. We are all random guys learning about great discoveries together.
Not everybody is right. And most likely our ideas will be seen as basic and outdated like the four giants.
The four giants of electricity and magnetism and such were great at manipulating the microscopic world to create amazing inventions but their ideas are only stepping stones to the achievements we have now and we will be stepping stones for the next generation.
Your animations are so beautiful. Thank you for these wonderful videos.
Thanks! I spend a lot of time on them.
@@ScienceAsylum Understanding such phenomena has never been this easy...
Love your work so much...
Being shushed has never made me laugh so hard.
Never seen It's Always Sunny In Philadelphia?
By now it seems like you could fill up an entire beginners lecture or high school course with your videos and, even without covering every technical detail, students would learn more and understand it better than by listening to most teachers.
Seriously, how is it that you manage to explain the essentials of a topic every time so on point
Beginners, definitely, but I would go even further with some videos. I studied some things in my second and even third year of uni.
I'll make a compliment that I should've made a long time ago. I appreciate quite a lot your lessons, they're among the best I've seen in my life.
The most impressive part of all this is that it's still common among the population to think that there isn't much skill involved in helping others, explaining something, teaching someone. And many think that expertise on the subject is the only skill needed to teach well, ignoring the deep needs of empathy skills, communication and linguistic flexibility, and many others. It's because of this common misconceptions that STEM teachers around federal universities here can be so bad at teaching sometimes. No matter how ingenious and great they are at research, they can still be dickheads with students.
And consciously or unconsciously, you've proven to know all this and much more than me about teaching strategies and skills. Your empathetic skills and considerations towards the viewers interests and doubts are strong, and one of your best assets.
The best part of this is that you also seem to go pretty deep on your knowledge of physics, enough for you go beyond the average teaching youtuber, and yet, you maintain your ability to teach properly that complex knowledge to your viewers, showing great skills to simplify and make concise extremely difficult concepts, enough for an interested student like me to understand.
Thanks Nick, keep being great.
Thank you for the kind words :-)
@@ScienceAsylum sir why light just don't go straightly while passing the slit? Please sir explain me
@@niloybhuiyan3374 literally watch the video, it explains your question...
sir
Good point. One thing that students don't realize is that public school teachers are actually certified teachers (with buttloads of training). College professors/ instructors are not trained to teach (unless they were former public school teachers). That's the main reason they are so horrible.
Unfortunately I don't feel it's common for the population to think, it occurs, but it's not common, uncommon potentially.
Love these timelines. The history of science is just as fascinating as the science itself.
Underrated comment!
prize for best illustration showing how peaks and troughs form, also depiction of it in 3d space
Honestly that's when the light bulb went off in my head. This was beautifully explained AND demonstrated!
Definitely check this video out. It does a fantastic job of helping see how the pattern forms.
ua-cam.com/video/gRX-s0p4HpM/v-deo.html
QuestionClones "but if the waves cancel, where does the energy go?" and Ha, again: if we think we already know the stuff then watching this video still improve the completeness and clearness of our insight! Such a short question but geni...Oh in short: I love these video's!
This science channel is my favorite on UA-cam. You are an incredible teacher Nick.
Love how you animated the EM field at 4:33 :D
Also, stay crazy like supercritical fluids (they just won`t stay inside the box ) XD
One thing I like about this channel is that you answer questions that are on my mind but other sources fail to because they seem like dumb questions. Like what happens to the energy of the wave? But it's not dumb it's just that you actually understand your audience. Great work. Keep it up, please.
"I said 'shush'!" is now my new favorite phrase.
Your description of superposition in a field is rather mind-blowing. Wow. Thank you.
You're very welcome :-)
Thanks Nick another great video to chip away at the magic tricks 👍
Really well done on the graphic work, very educational again. Thank you for this.
Thanks!
I've watched probably 30 videos on the double slit experiment, and none of them, NOT ONE, explained how photons are just waves and how the field is one entity and that is why it can interfere with itself or that superposition and interference are linked. Instead they all seem to give into some sort of mysticism and woo factor. You rock dude.
Yes dude the porpose of science is to dimistify something others are doing opposite..
Dido.. hopefully Nick can also demystify the mechanism that causes wave collapse/ and our seemingly mysterious perception of particles ...
Shooting other particles (electrons, atoms, molecules) through those slits creates the same interference pattern, so... you mean those particles are just waves?? The woo factor is still there, the quantum physics still has some mysticism.
@@marxk4rl that’s a legit point
where have you been all this time? Im just glad i found this channel :D
I'm glad you found it too 🤓
Finally at 63, with 4 college physics courses in my distant past, I finally understand. Via UA-cam. Did not see that coming...
You're welcome :-) Glad I could help.
such a beautiful explanation sir, thanks
You missed it entirely. We know light is a wave because if we wave at it, it waves back. :p
Right! I often do that with my shadow bro
Ha!
@@tiagol8200 Damn, mine only gives me the finger.
Best video just in time for my physics exam! Love this channel
We know it, and we don't know it. Our knowledge is in a superposed state of existing and non-existing.
The more i know, the more i know i don't know..
Thank you for this great video, love your channel! Could you please explain the pilot wave theory or Bohemian mechanics in one of your next videos?
I will... as soon as I'm comfortable enough with it to explain it. 👍

Finally someone explains this so it can be clear! Thanks Nick.
Time to learn things. I am okay with this.
Wow crazy scientist explaining much better than normal man.
Incredible explanation, great Nick! Please more about photons!
Brigadão para o sujeito que traduziu, belo trabalho!
Science Asylum's next video is going to be about how we know that photons are particles. You'll see.
that animation of how light travels in straight lines after the double slit to produce a wave pattern was helpful.
your the best youtuber i have ever seen
Great video. Great explanation on a theory most people struggle with.
Your video is more and more useful for me...
It would *not* be more accurate to define colour with frequency.
Colour is not an inherent property of light. Wavelength is, frequency is, colour is not.
It is useless to argue about the colour of light inside a medium.
What about the probability-wave collapse during measurement? I thought they acted like particles if measured
Not really. They only _appear_ to. We'll talk about it in the next video.
Steve Dixon If one puts an Avalanche PhotoDiode in a place where there’s an EM field, occasionally there will be an "avalanche" of current: the device was designed to do that occasionally, so it does it occasionally. If you put the APD in a different place, you get more or fewer avalanche events, but what causes that? Was it because there are photons or was it because the APD was designed to do that? If you look at the electrical signal much more closely, it’s not really an absolutely sudden event on the signal line: it ramps up very fast, but it’s not instantaneous. All modern experimental apparatus is the same: signal lines into computers, attached to exotic materials that are driven by exotic electronics.
Quantum theory doesn’t necessarily talk about "collapse" during measurement, it can also be taken to describe and predict the statistics one will see of everything that happens on a signal line, and jumps are only the first level of detail about what the signal level does picosecond by picosecond. Sorry: you asked a good question and I’ve given you my very idiosyncratic answer (and compressed enough, as well, that it’s likely incomprehensible.)
Yeah he left that bit out of the explanation of the double-slit, which is honestly one of the main points of the experiment, and opened the door to the whole field of quantum physics. Unless we figured out quantum physics over the last year or so, I always thought the door was still open as far as what light is, depending on what interpretation you used. In most, it seems to be that light is both. The most-accepted Copenhagen interpretation states that light is essentially a wave that becomes a particle. The pilot wave theory believes that light is essentially a particle that is pushed by a wave, so in effect, it's both. That being stated, we still haven't figured out which quantum theory is the correct one, so it's still largely up in the air. It is clear it exhibits behavior of both though.
@@taragnor nope.its only wave.if doesn't say in one video means doesn't mean he doesn't know it or he believes in what u say.
Great work again!
Students every where: "So light is a wave and a particle?"
Nick: LIGHT IS A WAVE. FULL STOP.
Some say "A Wavicle".
I think it's wrong though. As far as I know light is a particle when it's observed but a wave if it's not observed.
I’ve been known to interfere with myself. I am a wave?
Am I a wave ?
Yes.
this guy works for his money nicely
Thanks Nick, as a high school teacher these latest videos are perfect for the classroom. I showed my 10th graders your video on colour and they loved it... it covered everything they need to know and they were hooked for every second... you've pitched these perfectly! This new one is perfect for my older students and I just wish I had it a couple of months ago when we covered this! I'm just glad to know I have it for next year! Cheers!!
That's wonderful! Thanks for sharing with your students :-)
Ah commercial use; hope you're paying Nick for doing your job 😋
I think my brain shorted. Need to watch it again.
Those EM-Field & Wave-Interference Animations are so beautiful! And almost self-explanatory! Very nice work!
Thanks! I'm really proud of those animations. They're some of the best I've ever made.
I liked the way you described light as a wave, good job. I have a question though. Interference patterns are a property of waves ONLY? Could they happen in other cases? If yes, then why are we so sure that light is a wave and not the "thing" that has this property? In other words, is this property of light unique, does it belong only to waves? Thank you for making those videos and for any response to my question.
George Simos yeah pretty much only waves can diffract. This unfortunately makes everything a wave including, electrons, protons, photons, neutrons anddddd YOU
You are brilliant!! You're definitely like our very own, real life Professor Proton!!
Your animations are getting better and as usual i am left with more questions in my mind like - if light is an electromagnetic wave due to this interference pattern should we also consider other particles like electron as an wave in electrostatic field or both electron and photon as particles due to excitation in their quantum fields?(electromagnetic field vs photon quantum field) please answer.
You should definitely consider all quantum particles to be wave-like disturbances in their own quantum fields (photons in the photon/EM field, electrons in the electron field, etc.) ua-cam.com/video/Y7Ac8zKTD-E/v-deo.html
Now i understand the electromagnetic field is a toned down version of photon field that doesn't include most quantum nature of a quantum field.
First...always loved ur videos...❤
*Fourth 😉
@@ScienceAsylum thank you for your reply...i have lots of question in physics but noone tends to answer. even my teachers say don't ask silly question.i am obsessed.....i have cleared various doubts through this channel...thank you very much🤗
Woah that animation at 4:31 🤯🤯🤯
I was expecting you to talk about what fact made us first suspect that light is a wave, all the way to the confirmation that it is indeed a wave. But this was really a good video too.
finally someone give information about slits' length. thanks
make a video on the standard model
Awesome video as always!! Can you explain why the interference pattern disappears when you observe individual photons after they went through one of the slits? Instead you get two discrete lines on the screen in that case. Is that quantum weirdness? PLEASE TELL US!!!
Next video :-)
I'm guessing the next video will mention the photoelectric effect
And the blackbody radiation equation with the addition of the planck constant
2:18
So a superposition is basically just a linear function then, where f(x+y)=f(x)+f(y)?
I'm realizing more and more just how important linear algebra really is as I rewatch a bunch of your videos after taking a linear course and calc 3 (my calc 3 professor was _way_ better about giving examples of physical applications of vectors than my algebra professor was). Knowing even the basics of the math makes everything make _so_ much more sense.
Yep! That's all a superposition is (including the use of the word in quantum mechanics where linear algebra is a _huge_ deal).
0:53 I love this!
Did you ever get around to doing this experiment with a fog or smoke machine after all? Your visual representations are highly reminiscent of a conversation we had a while back.
Anyway, another awesome video. Also, have you ever thought of passing the beam through a strong magnetic field just to see if it would affect the diffraction pattern?
I remember the conversation. I'm not much of an experimenter though. Not really my thing.
The Science Asylum I thought playing with lasers, dangerous chemicals, and confusing your friends was the only reason to get into the sciences?
My life is a lie!
Thanks again for another great explanation
I wonder how I would have to place 2 light bulbs to darken my room thanks to interference :P
that’s what i was thinking, a flashlight that emits two destructively interfering laser beams, what would it look like?
You will never get less light than what already is there. But i suppose they could cancel out in some places.
Luke Haulin but lasers!
How do we know the various wavelengths of light? How can we measure them?
Thanks as always. Is that a probability wave or an actual wave?
An actual wave. In the E.M. field. That screen with points and crosses animates that field while the wave is passing throug it.
An actual wave. A wave in the e.m. field. That animationscreen with all the points and crosses, that animates the e.m.field while a wave is passing through it.
Love ur vids Nick!

“So what about photons?”
“I SAID SHUSH”
😂
Hehe thanks for replying to my comment ur videos are amazing and funny
Next: how do we know light is a particle? That's the really hard part IMO.
The most amazing part is repeating the experiment with individual photons which shouldnt produce an interference pattern at all. You touched on it briefly at the end but really should have explained that more because it has deep implication...
I'm making a whole video on it.
@@ScienceAsylum OK I will look out for it.
So light is not a photon? Nick what are you doing??🤔🤔
He said a photon is a wave. Light is always a wave, just sometimes its wave properties don't matter so we can treat it like a particle.
@@danbodine7754 shhhh😂
Light is made of photons, but photons are not what most people _think_ they are.
Very good pronunciation of Christiaan’s last name!
Thanks!
"I said SHHHH" lol
A little detector at the slits would change everything ;)
Yeah lol, that's where the experiment gets really interesting.
Does the energy to back into the field? I don't think so. I think the leaks and troughs are like positive and negative and cancel each other out. This is the one experiment that gets me excited about science! I did take away from this that the visual gradient is because of the curve of the wave. Nicely done!
BEST EXPLANATION EVER.
Hello, I'm a telecommunications Engineering student so basically anything wave related is what I know.
I understand how electromagnetic field work and all. But the question I keep asking that I never get an answer for is: what is the electromagnetic field exactly?
I know all the math and how it works but what is it EXACTLY? Like physically? What is the nature of the field that can be disturbed by a photon? Those arrow we represent coming out or in a charged particle, what do they represent physically?
I got into some quantum mechanics stuff to help me understand but nope, It made it complicated even more.
You ask a difficult question. What is the electromagnetic field exactly? It’s difficult to answer questions about something that is considered a fundamental fact of the universe.
First, a field is just a name we use for the collection of all points in space that we can associate some number to, like temperature or pressure or electric push/pull, usually more than one number and sometimes with a direction. It’s an abstract mathematical entity.
The electromagnetic field has numbers like energy, momentum (with a direction), amplitude, wavelength, and frequency. This field can be viewed as a combination of a stronger electric field and a weaker magnetic field that both have magnitudes and directions of influence (the arrows). Oscillating charges produce variations in the electric and magnetic fields that may be regarded as waves, the aforementioned numbers change from moment to moment and place to place in a self-replicating fashion influenced by its neighbors. At a quantum level, the numbers exist only in a superposition and do not change (or don’t have values at all), they have probabilities that change instead. Energy is quantized as well.
What exactly underlies a quantum field if anything, such that it can have probabilities at each point in space, isn’t clear. I think it is just about geometric relationships between things, or places where things could be. So a field just isn’t physical. It’s a background description of how interactions can play out.
Sorry that’s the best I can do.
Edit: The electromagnetic field isn’t caused by a photon. The field is an independent thing. A photon is just a persistent wave-like disturbance in some part of the field.
Yep, another mind blowing thing about how the universe works that I will tell my friends about but, I won't have any idea why or how it works. They'll never know that though because their minds will be blown and will turn into crazies them selves.
"the same interference pattern emerges" ummmmm what?? you REALLY should have mentioned that still, as soon as we have a detector on the slits to see where the photon passes, the pattern changes to conforming a particle nature. Without that, you make it sound confusing IMO.
Otherwise: a FANTASTIC explanation and visualization. i just had a moment where i felt a little bit smarter than before.
I'm saving all that weirdness for the next video :-)
So, does the material in which you make the slits make a difference? If it's made of a reflective metal, would there be a different pattern than if it were made of something that absorbed light completely? Just eluding somewhat to pilot wave.
"On the microscopic level light is never inside a material"
Mind blown haha
When are you gonna talk about quantum foam?
Why do I always see the double slit experiment explained with animation and not actual footage?
What Train Jackson said. Actual experiments are also designed to eliminate as many errors/external influences as possible, which makes them way too complicated to actually use for education. Using animations allows us to simply things and keep viewer/student attention on the correct details.
Next Video: How do we KNOW light is a photon?
Just Kiddin
But would be accurate as light does not only have wave-like properties.
following this channel not bcs of physics.. but bcs of nick's expression in video.. 🤔
Love these vids and your work so much!!! Quick question, how do the waves interfere with each other if singular photons are shot out?
I will answer that in my next video :-)
@@ScienceAsylum AAA you're the best! Ty
Type and amount of molecules and the way they bonded together in a typical matter (structure of that object) is responsible for a phenomenon called "Natural Frequency" and its harmonics. They are important in designing machines, buildings and actually everything so..... objects also have frequency/frequencies....only in different category.
Saeed Sh. That’s just what frequency of periodic force creates largest displacement. All objects have a wave function but determining wavelength and frequency from it is difficult
@@brogant6793 external force produce resonance only if frequency of those external forces matches natural freq. (constructive superposition sometimes in runaway situation until total failure), that is why we escape it by ramping up in gas turbines or increase its value to something outside of our scope by manipulating the mass of system....also natural freq. can be calculated....I do not talk about E=hf....as I said it...different category....nevertheless objects have freq. Unique to them.
Saeed Sh. I wouldn’t call that frequency. Its true there is a ‘natural frequency’ but again this isn’t relating to waves or wave frequency. I understand resonance and damping to affect said resonance, I’m just saying there IS a wave function for every object and that is what I’d term A’s frequency just like I dont term how frequently I breathe “my frequency” things have many frequency’s if you look from such a perspective
@@brogant6793 although I(and rest of mechanics) wasn't(weren't) waiting for your approval. Everyone's opinion is respectful by himself/ herself... even so, your answer is also appear to be that objects have freq.(not talking about calculating it).
Saeed Sh. Yeah we are just debating specifics at this point they’re 2 different types of frequency
This statement of a photon being a wave is...huh?! so a single photon can and will interfere with itself and a pattern is observed just like regular light...I thought a photon by definition is an indivisible packet of energy... Oh well, will wait for your next episode
It's indivisible yes (that is: we can't get smaller packets of light energy), but it's still "waving" in the EM field, so it interferes with itself.
It is indivisible in a sense, that you can't measure half of photon and let the other half continue on its merry way. The photon is either entirely absorbed or entirely transmitted. What is dispersed in a wave is the probability of being absorbed.
With the double slit experiment, this means that by firing individual photons, they will hit individual points on the screen. The points are not equally likely to be hit. The likelihood is distributed as a wave.
Correct me if im wrong.
Photons are not (always observable as) waves, they are particles or waves depending on how one observes them. In the slit interference pattern with photons we observe photons to exhibit wave like behaviour, but in other situations like absorption spectra or the photoelectric effect, the exhibit behaviour that suggest that light is made up of discrete packets we call photons. I don't think quoting E = hf is "proof" that photons are "waves", as you simply looking at the equation as "the frequency of the photon is proportional to the energy of the photon" may make little sense as im not sure in how far a single lone photon can have a frequency in the same way a rolling ball doesn't have a frequency (as frequency is the number of disturbances per unit time and when you only have 1 disturbance that doesn't really work i think). Instead, the frequency in the equation refers to the frequency of the light source (which suggests that there is more than 1 photon getting shot out).
Am I making sense or am I being silly? Am I missing something
The fact that you added the "not (always observable as)" is important. They're always waves. They only _look_ like particles when they occupy a small space.
@@ScienceAsylum If they're always waves, how could photoelectrons are only observed to be instantaneous after a given threshhold frequency. Light being a wave (and thus continuous) suggests that at any frequency, one could observe the emission of electrons from a metal surface as the wave would eventually provide enough energy through time for electrons to be released, but this isn't the case. Furthermore, if light acts as a continuous wave, we should observe all sorts of electron orbit jumps all the time when we shine any light on any atom, but again we dont. These things suggest that there is something discrete about light and thus light isnt exclusively a wave. Plus, electrons also give interference patterns, but they are particles, so individual photons giving an interference pattern doesn't render photons to be a wave.
1) Just because light comes in discrete packets of energy, it doesn't mean they're particles in the classical sense.
2) Electrons are also always waves.
@@ScienceAsylum While perhaps photons are a bit waffly when it comes to "is it a wave/particle", I think electrons are much clearer in that regard, as they impart momentum and have an observable mass. On the photons, true, it doesn't prove that they are particles but doesn't light's (occassional) discrete behaviour mean that one couldn't say "light is a wave, but it sometimes acts as a particles", because one can just as well argue "Light is a particle, but it sometimes acts as a wave".
Using a metaphor, if lions sometimes act like cheetahs and sometimes like tigers, does it means that "Lions are cheetahs but sometimes acts like tigers" (or vice versa). In the same sense, wouldn't it be more accurate to say that "light is a disturbance in the electromagnetic field that sometimes acts as a wave and sometimes like a particles" (meaning that light isn't particle nor wave, but simply acts like those at times).
Or am I just being pedantic?
I'm hoping to clear some of this up in my next video.
This video had to take inconceivable amount of time to make. I really appreciate your work and effort. I'm buying the E-book at least, cuz I can't support you monthly :/
It was a lot of work.
Now I know that a wave needs a medium to travel through. Like sound through air or water. Which medium does light travel through when going through outer space?
The electromagnetic field ua-cam.com/video/3TufSRaHB6g/v-deo.html
But, but, but... What about photon DETECTION on the slit entry, that change the pattern showing only the two slits? Aren't those, photons acting as particles?
Next video :-)
All things that exist must vibrate.
All vibration ceases at absolute zero. If absolute zero is achievable, and a substance is submitted to the temp, would it dissolve? Since vibration has come to a stop?
You make a distinction between waves and objects. Can the argument be made that all "objects" are ultimately made up of waves?
Yea basically they are
Hell you could say thoughts are a wave
Thank you for emphasizing there is only one electromagnetic field.... that takes the mystery out of super position.. why we perceive particles (in the wave function) at all still evades me ( seems very binary)
There are many ways one can define or understand the concept "particle" and in particular the spaciousness of such thing ... is it a point, is it a wave packet, do things ever really "touch" ... listen to the part after the main topic ... how big is a wavelength compared to an atom ... how big is a photon compared to an atom ...
Ok so, if you pass light, or a photon through a polarising glass, it comes out rotating in one direction. Doesnt the rotation of the light matter at this slit size? What would happen if you put a polarising glass before or after the slit?
Hey what about single photon behaving like a partical when nobody's observing...??
ROHIT BANSAL photons behave like particles when we ARE watching ;) the photoelectric effect is why Einstein came up with photons in the first place (sort of) and proves particle nature of light eg photons
The Science Asylum sure is one of the best channels in UA-cam. Nick Lucid is brilliant, unlike Vsauce who has gone downhill by time. Consistency and discipline is perfection. And I see that in Nick.
Edit - I like the energy this channel has.
DUDE THOSE ANIMATIONS THO
What program(s) did you use? Also, I'm hoping to find something I can do some basic (like Newtonian basic) physics exploration and modeling with; i.e. simulating gravity, collisions, etc., but without having to learn all of Unity or licence a prohibitively expensive game engine to do it. Know of anything like that?
I use Adobe After Effects (and a little Python if I don't have time to figure something out in After Effects). Neither one has a physics engine built in. I have to code it all myself. If you're looking for something quick and easy, I'd recommend Universe Sandbox: universesandbox.com/ It's only like $25 US.
@@ScienceAsylum I've actually been considering learning a bit of Python despite some deep-rooted college programming PTSD: I know the language is used for a lot of math-related contexts.
Universe Sandbox has been on my Steam wishlist for too long, though. If I ever find some time to actually play it, I will definitely check it out!
What happens if theoretically speaking one applying an entire wave at once of troughs to balance out all the beaks of the entire universe? Would that violate conservation laws?
Also more suggestions:
Quantum Tunneling
A multi part series of "how does it work" on computers from the bottom layer all the way to the top layer.
Also remember on a previous video when I asked if changing reference frames violate the 2nd Law of Thermodynamics but you said no because changing frames requires energy? Well what it there was a thought experiment demon who could "switch" between frames like a Director switches between shots.
