Excellent band, by the way.
Science Memes
Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.
Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Holy shit. That was pretty profound.
No u.
The cosmos is within us. We are made of star stuff. We are a way for the universe to know itself.
Carl Sagan.
This Carl guy sounds pretty smart. Maybe he should study physics or something.
An explosion is pure entropy. It's high energy releasing to a low energy state in an uncontrolled manner
We climb down the energy slope very slowly to reverse entropy and create order
The universe is like us - temporary order emerges as it slides towards entropy
Perhaps another way to think of it is that we're a patch of localised order in an overall disordered universe
Or perhaps more eloquently:
we're the standing part of a harmonic fart
I don't understand this, but it sounds cool.
But are we actually creating order? To maintain life's order, we are creating much more disorder somewhere else.
Life is but an entropy maximization machine.
On the overall scale of the universe? No, not even remotely close. On the local scale of the Earth, generally yes.
Well, as much as possible anyway. When considering mass alone, life is quite efficient.
According to Wolfram Alpha:
The sun produces 3.8 * 10^28^ watts.
A single human produces 104 watts (calculated through the average caloric intake assuming that intake ≈ energy consumption) through heat radiation.
Therefore:
1 kg of human converts 1.5 watt into heat.
1 kg of the sun converts 0.0002 watt into (heat) radiation.
And while I have nearly no understanding how entropy is calculated, from those values alone it seems like humans produce more entropy per kg than the sun. I'm pretty sure entropy is somewhat related to energy production though.
Yes, if you consider just a human-mass equivalent portion of the Sun then it's not doing much, but that's not really a useful comparison. We're talking about total net entropy here, not entropy per unit mass.
But yes, if it makes you feel any better, I'll concede that if you had octillions of people our total metabolic energy output would, in fact, be significantly higher than that of the Sun.
...just ripples in the carbon cycle, momentary standing waves until we lose coherence...
A single human may look organized, but collectively we are chaos
Meditate
Just recently mentioned the conscious universe theory in conversation with a friend.
synchroni-city
If we share this nightmare Then we can dream Spiritus mundi
Life is anything that moves, reproduces, senses, grows, respires, excretes and eats.
Consciousness is more mysterious and less well defined.
Yes, but how do living things come into existence? What makes a cell alive?
It's not about defining what a living being is.
Jiggling. It's about wiggling and jiggling.
“Jiggle physics is the real science. Everything else is stamp collecting.” - Einstein maybe
What is "sensing" or "growing" or "respiring" or "excreting" or "eating"?
I would define those terms, but you would just ask me to define the terms I used to define them, wouldn't you? Eventually, language is known by other people without being defined in terms of language.
Not really, i left out the term reproduce because i think it has some reality. But others like sensing — does an atom changing the electron cloud due to an electric feild or nearby atom count as sensing because it senses the presence of nearby atoms or whatever?
Won't growing constitute of some large mass body collecting more mass due to its gravitation?
The paragraphing has gone all the way through readable back to "I'm not reading this".
I heard Bill Wurtz voice while I read this
Even crazier space dust!
and then downvotes it
Actually I live in a skip but thanks for the pep talk.
Mind that textbook we did in school?
I’m still tripping
