[@h7opolo]

just because we lack the ability to detect, analyze, and describe atomic dynamics doesnt mean the motion is "random."

[@funkyflames7430]

That’s true, but modeling it as randomness works pretty well. I guess randomness should be defined more clearly to convey the orthodox idea.

[@EugeneKhutoryansky]

It depends on your definition of "random." It might not be random in the sense that there really is a pattern, if you keep track of all the molecules of the fluid. But, it would still be random in the sense that we are unable to keep track of all the molecules of the fluid, and therefore the behavior of the emersed particles is unpredictable to us, given our lack of knowledge. Then, if we bring Quantum Probability into it, then it seems that probability is an intrinsic part of the way fundamental particles work, and it is not simply our lack of knowledge.

Brownian motion is not really random, as particals are in constant collision with molecules ( water H²O, gases, etc.) Effected by gravity or frequency, energy, ether... movements would trace out a pattern of the fibronacci sequence if viewed in a 3-D weightless environment by forces akin to the intermediate axis Theorem or torque ....

[@EugeneKhutoryansky]

I am glad you liked my article. Thanks.

[@madisondampier3389]

The experiment with the pollen in my opinion goes to show just how life could emerge through just the random interactions of particles with unique attractive and repulsive properties. What people like to ignore, or neglect to consider, is that "inert lifeless atoms" don't just sit there and wobble. They dance and bond into unique chemical structures that now have interesting properties of, from the perspective of any single atom, a much larger and more interesting atom. Something a little different than everything else around it. A bigger chemical structure has just that much time to have multiple interacting parts with heavier atoms to get us to intelligent multicellular life, where we are now. Pollen just needs to find it way to another plant and the structure of the chemicals will ensure that reproduction occurs, if everything is in the right place. Beauty which many don't seem to think counts in the natural arts.

[@morristgh]

Very good thoughts! The problem lies a bit deeper I am afraid. In order to understand this you have to understand the symmetry of the carbon atom. If you don't want to read my explanation I suggest you look up "chirality" and just skip the next paragraph. In essence if you take a tetrahedron with 4 distinguishable corners, there are two possible unique arrangements you can create. Both arrangements are not equal and one can not be generated from the other without actually detaching one corner and attaching it to the other. For another example of chirality look at your hands. Both hands are set up in exactly the same way, they are mirror images of one another, but they are not equal. Now, in chemistry the carbon atom creates 4 bonds in a tetrahedron geometry, if all 4 ends attached to the carbon are distinguishable, you have a chiral molecule. This is not at all rare, in fact every amino acid (except for glycine) is chiral. Glucose is chiral, etc. In order to be more brief in my explanations I shall distinguish the two forms with R and S. This is the official nomenclature but it really doesn't matter what you call it. Think of R as "right" and S as "left". So far so good, we have chiral carbon atoms in many biomolecules so what? In fact both R and S forms have the same physical properties, they melt at the same temperature. Why should we care? Well life cares, not only do we have a left and right hand we also have right handed sugars and left handed amino acids (except for glycine which is not chiral) in our body. All of them are. If you have a pool of molecules sitting around and reacting there is nothing that will force a molecule to be attacked from the right side or left side. Both sides have a 50:50 probability and if you have a large enough quantity of molecules (which is necessary in order to create life) you will always have a 50:50 distribution between the two. I should note that we have found ways around this in chemistry, but they all can be traced back to actually extracting a molecule from a living being and using that information in some way to force the reaction into one direction. So in the way you've worded it, life just happened by chance. It happened merely by the right molecules reacting in the right way in order to eventually form an assembly that we could call life. But the universe isn't long enough to let that chance be, there has to be something we're missing. Steve Mould created a video around the subject afaik

[@TETRAP]

I have been interested in this topic for a long time, but I do not know where to find more information, so I will write here :) Why is Brownian motion possible? The particles collide, they lose energy... in an insulated system, the temperature should drop. Can such a phenomenon be observed? Is there any limit to the particle diameter at which mentioned motion is observed? For example, for air suspended particles. Is mass / density or diameter more important in this case?

[@EugeneKhutoryansky]

If heat can flow out of the system, then heat can also flow into the system, and the temperature will eventually be the same as the surroundings, for thermodynamic equilibrium. For a perfectly insulated system, heat can't flow in or out, and the temperature of the system will stay the same. My understanding is that Brownian motion happens for any particle diameter. And Brownian motion occurs both in liquids and in gasses.

If the probability distribution is a Bell curve that is never zero no matter the distance, does this imply that the particle can occasionally travel faster than light?

[@EugeneKhutoryansky]

That depends on whether or not we bring Quantum Mechanics into it.

[@markusheimerl8735]

Does the brownian motion result from the repeated collaps of the wavefunction of two neighboring particles?

[@EugeneKhutoryansky]

Brownian motion would occur even with classical physics.

[@markusheimerl8735]

@@EugeneKhutoryansky In a classical sense its a vibration of a ball. Then each temperature would have a corresponding vibration frequency right? A vibrating ball in empty space would seize vibrating if no external energy is added to it. But a particle of temperature X in empty space would only lose temperature through radiation. Hm. I cant make sense of brownian motion and temperature in a classical sense. Can you help me?

So how does a single atom brownian-move? As long as it doesn't bump into anything, does it always move in a straight line? Or is the movement always erratic?

[@EugeneKhutoryansky]

Even if you have a single submerged particle, the fluid it is submerged in is still composed of many atoms and molecules, and it is these atoms and molecules that the submerged particle will collide against.

[@Breakfast_of_Champions]

@@EugeneKhutoryansky Thank you for the answer, but I think I should have said "in vacuum". I guess these particles then always move in straight lines and are called radiation, or stellar wind above a certain size.

What I don't get, is why they spread out. The colored particles have the same density and size, having no "advantage" over water particles. So shouldn't they stay in about the same place?

They spread out simply because of their random motion.

2:56 Minor Comment: Perhaps instead of "their positions" it should say "their aggregate positions" ? Cheers, and +1

[@EugeneKhutoryansky]

I believe it is correct the way it is. I am referring to the probability distribution, and we would have a Bell Curve probability distribution for the position of even a single particle.

[@RovingPunster]

@@EugeneKhutoryansky I realize i'm splitting semantic hairs a bit, and my point is at best a small and subtle one. At 2:59 it says "the bell curve will always remain centered on the original location of the particles" (note the plural, because bell curves apply to a finite data set ... in this case the particles in the example). However, taken together with the statement at 1:50 which accurately describes how brownian motion causes the particles to diffuse throughout an area, the minor issue i'm thinking of involves diffusion into a bounded space albeit with an off-center starting position. Let's say you upend a test tube of xenon gas into one end of an empty shoebox - when the individual atoms diffuse into the air within the box, the distribution doesnt seem like it would be a bell curve, because a lot of them would diffuse in the obvious direction. That's all I was suggesting - the wording evoking a bell curve of positions can seem a little imprecise, depending on how you picture it, and if/how the space is bounded, so I thought a slightly more generalized wording might help. What that wording should be, i'm not exactly sure. 🙃 Anyway, cheers ... I really enjoy your content. +1 😄👍

[@EugeneKhutoryansky]

Yes, I am assuming that there are no boundaries to where the particles can be. Otherwise, the distribution can't be a Bell Curve, because the tails of the Bell Curve extend to infinity in both directions, without ever reaching zero.
