Molecular Dynamic simulation of 'salt' water droplet

[Emperorlawson]

I'm more or less ignorant of biochemistry, so you'll have to pardon this, but what does a salt water droplet have to do with emergent life? I'm not saying you're wrong. I'm just curious.

[mamolian]

Thank the spagetti monster we have clever folks like you Thunderbr0 working on research for the good of us all! ;)

[saxmanchiro]

I saw the hand of god in this. It was over in the right corner, next to a vibrating molecule. I swear!

[dXoverdteqprogress]

Is this thunderf00t's second channel?

[WickeDFate4]

@dXoverdteqprogress Yes. His beautyintheuniverse channel is another with great videos.

[PaganGlade]

Looking forward to the videos you will be doing on self replicating life, fascinating stuff, can't wait! ~PG~

[mhale71]

this should be on the main channel!

[lostismyconstent]

this reminds me of a heart for some reason

[viicISrotcib]

consider what we know today compared to a hundred years in the past, and what we will know in the future.

I love science, and the universe!

[ilackedtheheart]

So is this how water breaks apart salts into their Constitution ions? This is pretty cool TF.

[Vanja4life]

When you see something like this, the "god must have done it" argument somehow fails even harder.

[DontTaseMeBro77]

Kevin is offended, he finds Sodium rather arrogant and insensitive.

[Paxmax]

I will not click "Like" because I did not understand....

[tazer95]

@Paxmax I will click "Like" for that very same reason.

[Paxmax]

@tazer95 hehehe! each to it's own =o)

[butsgalore]

I don't see how this video can be used as an example of how the self replicating emergent life is more an inevitability than improbability.

It's nice to see the molecular dynamics of salt ions and water molecules though.

But not very related to self emergent life.

[virumoz]

@butsgalore -- if the improbable is happening trillions of time over billions of years, it becomes inevitable. It's the law of large numbers in a way. It works with organic molecules too, but maybe that simulation is best kept on supercomputers.

[FHomeBrew]

If this were to be "recorded" in "real time", how cold would this substance be?

[Octoschizare]

NaCl...? So the sodium cations are forming nanoparticles? What's up with that? Shouldn't they repel? They don't even seem to be densely surrounded by the oxygen end of the waters.

And I guess the simulation is of a tiny droplet in a water vapor gas under zero gravity?

[L00NGB00W]

@Octoschizare Just speculation here, Not sure of the accuracy of the sim, but I think that as the Chlorine Ion is stripped away, The Sodium Ion must immediately bond with the nearest electrical charge. Be it several water molecules, or another Stripped sodium atom. (Which is more likely due to the fact that the sodium is in a dense crystal lattice.

The result behaves almost like blobs of oil and water on a quantum level. =\

[TomValedro]

science is boring. I rather read stories.

[hobbitsarecool]

What are the blue things? I can identify the water and the chlorine but the blue structures don't seem to be sodium.

[L00NGB00W]

@hobbitsarecool I'm pretty sure that:

Red = O

White = H

Green = Cl

Blue = Na

If you look closely, you can see that:

The Red(+) is attracted to the Blue(-) Ion.

And that the White(-) is attracted to the Green(+) Ion.

Although I'm not sure why blue is clustering. I'd assume it's because Cl only has one empty valence electron.

[Octoschizare]

@L00NGB00W Not to be picky... but all your charges are reversed. The oxygen end of water is a negative dipole due to it's electronegativity, ionic chlorine is negative (-1), ionic sodium is positive (+1).

[L00NGB00W]

@Octoschizare Oh that's fine. I was a little unsure. You're right.

I imagined that since the H portions of the molecule were balanced, they would be negative. Because their electrons were outermost.

But when you consider that those electrons are bound to the neigbouring O atom, then the (+) nucleus of the H atoms would be 'exposed', so to speak. And present a net positive charge.

[hobbitsarecool]

@L00NGB00W

My confusion stems from the fact that if you look closely, there are multiple blue spheres stuck together. Seeing that sodium chloride is a BCC structure, it would not make sense that multiple sodium atoms are clumped together. This also does not make sense because of the plus one charge the sodium has due to ionization due to the chlorine. Maybe there is something going on which I don't know about but it seems illogical to me that it is sodium.

[L00NGB00W]

@hobbitsarecool It is hard to say what the composition of the 'salt' is.

If you strip an electron away from a sodium atom, you're left with a full shell underneath. I don't see how they could bond together. Unless it's possible for a sodium atom to hold an ionic bond with eight others... I have no idea... but it sure is fun to speculate! ;)

[barakuda1111]

This kinda blows my mind. Something thats not "alive" and it has so much movement. Makes the border of alive and not alive so.... blurry.

[Halflifefan54]

@barakuda1111 I agree man.

[shlunko]

Always nice to see the simple things such as osmosis up close.

[derAnubis]

@shlunko Errr... osmosis requires two solvents with different concentraions of a solud in it and a semipermeable membrane. Otherwise there is no osmosis because the liqiud can't balance out the concentration.

Or did i miss something quite important in the simulation?!

[Mandalor91]

@derAnubis Errr... nope.avi -osmosis only requires a SINGLE SOLVENT with different concentrations of a SOLUTE and a semipermeable membrane. There is no requirement for there to be two solvents. Namely, this solvent is water; the different concentrations of the solutes, because of entropy & thermodynamics, cause an imbalance in water potential, forcing the solvent (not the solute, particularly in the case of larger molecules) to diffuse across the semipermeable membrane.

[shlunko]

@derAnubis my apologies, what I saw was the attraction of water molecules to salt; the end product of osmosis. After sitting through a three hour biology exam the other day, my brain's ability to process this kind of simple data has become somewhat fuzzy.

Never the less you are indeed right, so thank you!

[volound]

Suppose.. that little things, behaved very differently than anything big.

[L00NGB00W]

@volound Such is the quandary betwixt Quantum Physics, and General Relativity

[MICKTAM12]

nice vid phil

[Jallenbah]

Did you write this? It's an impressive simulation. Simple, but complicated at the same time.

[gspahr]

It's the FSM!
