It's time to fact check your privilege, gentlords.

ITT: We post facts we've come across recently or that we find interesting.

I was looking at the 2nd Law of Thermodynamics (after seeing pic related), and it eventually led me to the "Arrow of Time".

Smashmouth, widely regarded as one of the greatest bands of all time, was largely manufactured by corporate interests. Everything from the songs they wrote to the way they dressed was carefully crafted by market research and marketing deals.

Five interesting things I found out about Leonard Simon Nimoy today.

1.) The "Vulcan nerve pinch" concept on Star Trek (1966) was invented by Nimoy when he and the series' writers were trying to figure out how an unarmed Spock could overpower an adversary without resorting to violence.

2.)Had a pet store in Canoga Park, California during the 1960s.

3.)Hit #121 on the Billboard Singles Chart in 1967 with "Visit to a Sad Planet" (Dot 17038).

4.) Is the only actor to appear in every episode of the original Star Trek (1966) series.

5.) Was an accomplished photographer (specializing in black and white images). He enjoyed photographing "big sized" women both clothed and nude. He hated using the term "fat".

Before the Battle of Hong Kong during WWII, the British abandoned the Hong Kong population by evacuating all official British citizens. Those few soldiers who were left were the city militias, a few remaining British soldiers, and hired Indian mercenaries. The following battle saw the Japs bombard the city with aerial attacks and land massive warships in the harbour. Skirmishes broke out throughout the city streets, injuring a large number of civilians and eventually pushing the merc and militia forces back. When I first read about it, the battle seemed pretty badass. You had the underdogs fighting to protect the city that the magistrates and upper citizens had abandoned versus an all-consuming imperial force set on stamping out any opposition.

would someone care to explain the second law of thermodynamics and what thermodynamics are.. how it relates to Evolution.

I myself have a limited understanding of it since I'm more of a mathematician than a physicist, but I believe that the 2nd Law of Thermodynamics states that in a given system, entropy (or the chaos of that system) will increase over time, correlating to OP's arrow of time - or the continuous change of matter. Basically, the universe will become more disordered over time and entropy is the movement of particles particles's energy at an atomic level.

An example is if you drop a pebble in a pond, you'll see the ripples moving out. Even if you didn't see the pebble, you could see the ripples it made and conclude that the ripples will spread out until they reach the ends of the pond and that the rock was dropped at the point from which the ripples originate. If the ripples were going in reverse (towards the point where you dropped the pebble instead of away from it), you would realize that the entropy was reversed, which is impossible since it would mean that matter was acting in a way opposite to how it is destined to act and the energy was collecting itself in a way that it shouldn't be. This would entail that time was in reversal.

I think the guy in OP's image is saying that evolution cannot occur because it is a coming-together of entropy, which by its definition is supposed to be matter's matter's energy's gradual tendency towards chaos.

My opinion: This assumption is flawed because entropy is subjective - if you think energy is gathered in a certain place and you call it organized, but someone else sees energy arranged in a different way and calls that organized, then you have two definitions of what ordered energy is. If more people think other things about how organized energy looks, then we have even more definitions. It's incorrect to assume that because energy disperses or rearranges itself over time, evolution or a building of the perfect living being cannot occur. If anything, I think it would just suggest the randomness of evolution, though evolution has more to do with matter than matter's energy.

Cheers Lounglie.

The fallacy occurs, not in the definition of entropy, but in the definition (or lack thereof) of "closed system". Although your observation is interesting, "entropy" does have an understood and measurable definition. Great example with the pebble, though.

The second law states that all things - not individually, but on the whole - tend towards entropy in a closed system, such as the universe as a whole. The person in OP's pic, then, has gone so far as to call the earth, or even his own body, as a closed system, which it isn't. People and the earth both give off and absorb outside radiation, thereby making it an open system.

tl;dr - evolution does not contradict the Second Law, it just means something's going haywire somewhere else outside our small sphere of influence.

At the very least, there's nothing we know about the laws of physics and thermodynamics that state that a system as infinitely vast as the universe can't randomly assemble life and then break it back down into chaos and nothingness over time.

Time is all very relative, after all. The way that we see microscopic organisms living and dying in a matter of days is not unlike how Earth looks from a cosmic perspective. The entirety of human evolution and history, as we know it, is an infinitesimal amount of time compared to other cosmic events.

If the whole system is trending towards entropy, as we think it is, there's nothing saying that things can't accidentally be created, change over time, and then eventually give way to entropy.

Which is only slightly ironic given that nothing will ever be as still as the heat death of the universe.

Philosophically speaking, you have nothing to gain from fearing death. Just as you shouldn't fret over all the time that happened before you were born because its already happened, there's no reason to worry about dying, because you've still got time now, and everything after won't matter, because you'll be dead.

Evolutionary biology major here. >>2869 has a good explanation of the Second Law, but allow me to explain a little more about how that relates to evolution.

Anti-evolutionists (i.e. creationist scum) argue that because the 2nd Law of Thermodynamics states that energy in a closed system tends towards greater amounts of entropy, it'd be impossible for more complex organisms to develop because that would require energy.

And on that line of thinking they're correct: more organization does require energy and in a closed system, that'd be impossible.

Thankfully, we don't live in a closed system, but an open one. The Earth's mantle and the Sun provide the necessary energy, thus allowing evolution to occur soundly within the Laws of Thermodynamics.
