Universe sure is a clockwork of some sort. On some scale so mechanically simple like filtrating salt particles. On subatomic scale, a very small machines, tiny little quantum computers with possibly infinite complexity, traveling through invisible "filters" of fields in spacetime. And even the most meaningless of them like neutrinos have their role in shaping the large structure of the cosmos, which itself is like a huge machine. But still possibly in all it's vastness, only a small, even sub-atomic part of much greater cosmos. Is it possible that there are larger multiversal dimensions that we haven't observed, or will be in future? I mean, mathematically possible, like continuum hypothesis? In fact, I wonder do we live in a universe, where continuum hypothesis is false?
@@LasseJ789 Yes, but when something cannot be disproven mathematically nor by observation, that something is a possibility. There is a possible universe where that something is true, and we don't know whether that something is true or false in our universe. But what would it mean to our physical level "reality"? Mathematics are the most real of the realities. Physical laws can vary between universes and even in same universe at different times. And unlike observations, there's no way mathematics can be wrong.

Just filtering the particles would be what we had at the beginning of the video, before the force was applied to create pressure forcing all the small particles to the left side.
Filtering is 'straining' and doesn't concern concentration. Osmosis is 'diffusing' and is dependent on concentration. Reversed Osmosis is applied pressure to make 'diffusion' against the concentration-gradient possible.
@@DreadX10 Thanks. So what is the benefit of doing it the "osmosis" way? If you have a membrane that can block salt particles and let water particles through, why not just let it flow through from top to bottom under the power of gravity instead of having to apply pressure using an electrical motor? Granted, then you'll have to call it "filtering" instead of "osmosis" but it seems to me it will achieve the same result with less energy input.
@@JohannY2 Hm, not sure, maybe just: filtering clogs by area of membrane. diffusion clogs by volume of membrane. So less cleaning/maintenance for RO. Also size could be a factor but I've never seen how big a (natural) filter-system would be to make the same amount of potable water.
The visualization was amazing! Is filtration in home water purifiers (where water passes through a porous filter due to gravitational force) considered reverse osmosis?

I have an unrelated question. The orbitals around the nucleus of an atom are actually standing waves right. And they can only take certain amount of energy (hence hopping between orbitals) Then how can hybrid orbitals exist How can an energy level between 2 adjacent (in terms of energy) orbitals exist.Especially considering one electron alone (for example an exicet hydrogen atom) cant simply occupy said hybrid orbital
I mean I recently learned the hypervalence thing is caused by some weird resonance structure and not by hybrit orbitals and it made me even more curious about it :p
Atomic orbitals are the standing waves state of electrons when the atom is not bound. When atoms form molecules, the resulting joint states of electrons (from the two atoms that bond) that form the bond are linear combinations of the atomic orbitals (Linear Combinations of Atomic Orbitals), these are called molecular orbitals and they have different energy levels than the atomic orbitals, and a larger difference between the highest occupied molecular orbital (HOMO) energy and the lowest unoccupied molecular orbital (LUMO) energy increases the bond stability.
Why not use a top and bottom approach with the method of "pushing the wall to the filter" being instead shake the top part until the desired atoms fall to the bottom?
I love these very clever videos and the visual way in which you explain concepts. However, I find them too slow and struggle to stick through to the end.
? Not sure how your explanation reverse matches mine, but.. When polar water molecules get electrostatically attached to the salt ions in the right, more water can (and must!) spread to the right via diffusion (entropy). When salts are saturated with water molecules, the diffusion gradient levels out and no more water is moving. That is called a equilibrium. Osmosis can only happen between compatible molecules, here as a polar binding to an salt ion. Did that fit with what you were saying ?
No, there does not need to be attraction between the particles. Osmosis happens even when the salt ions are replaced with any particle unable to pass through the membrane, regardless of the extent to which water is attracted to these particles. I go into this in a lot more detail in my other video on osmosist at th-cam.com/video/2OOvMiKCp8A/w-d-xo.html
Look up: molecular sieve, ion exchange membrane. They can be molecules like tiny cages where only small molecules can "fit" through the bars, or functionalized natural molecules (micelles and cell membranes) or artificial polymers (for example Nafion) with pores. Your body is literally built from these membranes, so at some level you already know how to do it!

In terms of "filtration" you can separate for example, by distillation (vapor or freeze phase change), differences in diffusion rates, centrifuging, chromatography, etc. So there's a lot of ways to do it. Reverse osmosis is filtration by forced diffusion through a membrane.
Always thought reverse osmosis was something super fancy. But it's just a filter. Not unlike the filter you use for your coffee. Sure your probably using a much finer filter and you require actual force that is more than just gravity to force it through the barrier
It is a "filter" but unlike say, a macroscopic filter like a sieve, there is a pressure associated with the random motions of the particles which is going to be dependent on the temperature, and you need to exert pressure to compress the particles to separate them. Because the larger particles can't pass through the barrier, these are being compressed into a smaller volume than the particles being separated, and you have to apply enough pressure to squeeze together the larger particles when you squeeze the smaller particles through the barrier. For charged particles (ions in salt are charged and water molecules are polar), there is an additional energy associated with the electrostatic forces so that these forces must be overcome as well. It's a dynamic problem due to the thermal motions of the particles which makes it a little different than a sieve for macroscopic particles.

@@David-bh7hs the size of an atom is basically the entire electron cloud around the nucleus, because the nucleus itself is a few femtometers in size, you wouldn´t even see it in the video, the image would be all black if painted in real scale. Thatś why we consider the size of an atom its pure electron cloud (the probability of the electron being found at some point at a precise moment in time). I wonder why you aren't complaining about water molecule shape if we talk about scales, that would be more right thing to claim, because water molecule is not round , it is V-shaped because it is polar
@@absolute___zero I'm more griping about how salt ions are portrayed. They would either be much larger conglomerates, or surrounded by water "V"s like you said. I'm sorry if this imagery is hard to explain in words. Obviously if we wanted to be this specific we'd also want to change the gate and sides of the box to be more realistic too...
Why not just call it filtration through a semi permeable membrane rather than reverse osmosis which gives impression the laws thermodynamics are being violated ? It would also be much more descriptive.
@@EugeneKhutoryansky What's that gotta do with his question? It's an EXCELLENT question. In fact, it's EXACTLY what EVERYONE wonders - and most never learn.
No, because we are adding energy to the system. This is the same way in which using a piston to compress a gas into a smaller volume does not violate the Second Law of Thermodynamics.
Yes, but it takes a lot of energy. Desalination is consuming more of the world's energy, especially as more people live in places with limited water resources. Also, the salt you remove from the water can make the ocean around the desalination plant hypersaline, which can be another problem.
@@profdc9501 1. Build a batter Reverso Osmosis machine, because my grocery store (Whole Foods etc.) has one. 2. Build it out in the middle of the ocean over a brine pool, you act like the planet will die if we move around resources.

Maxwell's Demon is a different, because it doesn't involve any transfer of energy to the particles. I cover Maxwell's Demon in my video at th-cam.com/video/8Uilw9t-syQ/w-d-xo.html
