Entropy.

[Shadowprophet]

Forgive me, This one won't be so extravagant, I feel like Entropy is a topic that really should be covered here.

There are lots of applications for entropy, Ultimately, There are so many thoughts on Entropy, I don't quite fully understand it. It is said that entropy is disorder, Chaos, for our own convenience in mathematics we resolve that entropy is random. "Hince the Chaos and disorder" And yet. We have evidenced that entropy is not random in the atomic half-life, The half-life is interesting, in every condition the half-life can be perfectly predicted. "This is not Chaos".

Wiki Says,
In statistical mechanics, entropy is an extensive property of a thermodynamic system.
This is because physical properties are categorized usually as intensive or extensive especially within a system.

Like that of the universe, My Question that I'm working on right now is, Then, If Entropy is an extensive property of a system, Is the expansion of our universe the cause of entropy because of Heat Death? Is Entropy and disorder, The physical manifestation of heat death in action in our universe?

Chaos is not random, or at least not probabilistic. It is deterministic.

Radioactive decay, on the other hand, is random, as quantum mechanical processes are thought to be random (without getting too philosophical).

The half-life of a radio-isotope comes from the statistical expectation of when any such nucleus is likely to decay. Because radioactive samples typically consist of vast numbers of atoms (there are about 100 million million million atoms in a grain of sand), this expectation evens out to a nice average able to be used to accurately predict the future radioactivity of a sample.

It is similar to flipping a fair coin. If you flip it five times, you might get two heads and three tails, or four tails and one head, or five heads. However, if you flip it a million million million times, then very nearly half of those will be heads, and very nearly half will be tails, despite the outcome of any coin flip being random.

It's been a long time old friend. I'm glad you're back
