You have a gift and a lot of tenacity for explaining these ideas. I wish this video had existed when I was in my undergraduate program. In business school, Brownian motion is just a piece of jargon thrown out there to attempt to explain the market movement in stock prices. Had I seen this video, I think this would have greatly increased my appreciation for the underlying mathematics. Wishing you all the best in the continued production of these videos!

Hey, I just wanted to say, ur videos are super fantastic, especially the one on the Schrodinger's wave equation. Im a high school student and I never really understood it properly. I was calling all my friends to explain it to me as my exam is nearing. But ur video was just absolutely fantastic. It explained everything from the very basic level. It even made me pause, take out my pen and paper and solve the KE + PE derivation myself. And ik I really dragged this comment out and if by some miracle u r still reading, I wish u all the very best!!

@@SuperAronGamerMNO I thought the same, but the definition proofs us wrong(or better nitpicking) see oxford dictionary -> bass, (also bass guitar) ... So a bass, a guitar, a 12 string, ukulele, etc. are all part of the family of guitar-like instruments. Oh and you are wrong. It is not a bass, it is an e-bass:P And all that shit is open for interpretation because it is spoken/written language and not mathematical axioms. Meaning of words must be agreed on, like the "taxonomy" of the guitar or lute family of instruments. But what is more important than this BS is that Jade's mom is really cool:)

I first learnt about Brownian Motion from reading random things in my high school science textbook. But I also learnt about it because it was mentioned in The HitchHiker's Guide To The Galaxy as part of a finite improbability generator: the source of randomness was a "nice hot cup of tea". It's great when popular culture surfaces a science detail like that.

[@doulos2309]

Hi Jade, the ink/dye disperses faster in the hot water not only due to increased Brownian motion (diffusion) but also due to increased convention currents as the water temperature differs from ambient : "Mixing by Convection If the container of water is warmer or cooler than the ambient air, it will develop convective flow patterns as the water approaches the ambient temperature. In the case of cold water in a warm environment, the sides of the container conduct heat to the periphery of the water. The cool, denser water at the center sinks. Food coloring added to this sinking center column will ride the convective flow to the bottom of the container, but then it will also ride the flow up the sides, back to the top to cycle around again. This flow serves to agitate the solution, speeding the diffusion."

[@beactivebehappy9894]

This is what should be TAUGHT in high school. Instead, I was taught about the kinetic theory of gases and that, the temperature is basically a measure of kinetic energy of molecules. On a side note, I was taught about the Brownian motion and the random movement of particles in the chapter pertaining to colloidal solutions and how Brownian motion is a property (as if a solution labelled as colloid inherently came up to have such motion). And about the discovery of presence of atoms or molecules (not the models but the actual concept) was simply taught as the Dalton’s theory and how ancient Greeks also mentioned about it, which is not untrue, but completely shoves the fact about Robert Brown and Einstein incident under the shelf. I know that the curriculum and academics is very time bound and there are very few people who pursue a subject out of curiosity and passion for learning (at my place and surrounding cities), many students opt for science out of career scope, or in the way that they went to kindergarten, where the knowledge was completely unrelated to what they like. I mean no one went to KG by telling their parents that I love the ABCs.. They were just put into it like herd and cattle. This rant is getting longer, but my point is that they have to teach this at school somehow.

It should be noted that stock price fluctuations (like Brownian motion) are examples of Levy distributions, which have the rather counterintuitive property that they can have variances that diverge, even though they're quite well-behaved. In particular, Brownian motion (or, more, accurately the Wiener process that describes it) is decidedly non-Gaussian in that it has "fat tails". We see this when there are sudden large shifts in prices that a Gaussian-distributed measure wouldn't exhibit.

Beautiful demos! One interesting observation, the ink in the cup with the hot water, it didn't go into the lower cylindrical part of the cup, and only start to "diffuse" in towards the end. I doubt this is simply because of the geometry, because if it was, then the line wouldn't continue to be so sharp even away from the glass walls. Maybe the geometry makes somehow makes the water temp less uniform.

Can I just say Louis Bachieler used Brownian motion to model stock prices 5 years before Einstein. And then we used a geometric Brownian motion to model the famous Black-Scholes model (although the latter was much later). The fact that the BM is continuous throughout time makes it really useful (at a basic level). Stock markets exhibit "jumps" for which BM is a little bit useless.
