Let me start again...

So of all the video I´ve been involved with for Sixty Symbols

Numberphile

and Brady´s million other channels

The one I´m least happy with by far

is the one we did in entropy

We even then did a follow up with a "solo mea culpa"

Where I uhm... pointed outs where there are some importants details

seeing where we just gloss over

I really wanna revisit entropy and Brady is gonna endorse me, what is great

What it might and might not

A lot starts from this

the work of this guy

a guy called Frank Lambert

And notice, It says Disorder- A cracked crutch

for supporting entropy discussions

So every time you hear entropy

mention, or the vast majority of times

I'm certain on the undergraduates

I'm certainly in the other Sixty Symbols video we did the same thing

We made this link between entropy and disorder

For a person who isn't a scientist and even for a person who is a scientist

that is actually a very difficult and very confusing link to make

because: for example

the argument is that, you know...

entropy is always increasing...

disorder is always increasing... How does this happen?

so this is from my kid´s crystal growing kit

So we get crystals. How do we get lovely structures like this?

Beautiful structures. This is the crystal structure of silicon

how do we get this extended over, you know

huge pieces of silicon

How much more ordered do you wanna get?

And then the argument is that disorder is always increasing

How, then, do you take, you know, atoms in a melt... or atoms in a gas phase and this how we grow silicon

They're pretty disordered, you would argue

And then they hit the surface, and they grow and they built, and they form this structure

So, that seems to be, from on the face of it

a pretty good example of something which is very disordered turn into something very ordered

That's the issue with using order and disorder to explain entropy

and this is something that this guy, Lamberd has been banging on about for quite some time and quite rightly banging on about

Because it's exceptionally, exceptionally misleading.

I wanna cover just very briefly, uhm... two aspects of this

You know, you could then quietly right ask me Well, you know, how it does happen then?

Does it breaking the secound law of thermodinamics?

The fact of to see in this apparent disorder to order transition

intead of other way round?

Have the laws of thermodynamics suddenly gone wrong?

Have we missunderstood everything?

The important in here is if you got to take into account the entire system

You've got to take into account whether the system is closed or opened

if those energy or matter flow

All of those different things, we can even reduce it further to make the argument

of this even simpler, the important thing that we are neglecting

When we talk about just the atoms forming in order or disorder

Is what's the role of energy

and in particular when those atoms bond they give off heat energy

and that heat energy is an exceptionally important contribution to the "disorder" of the system
