What Goes Through My Head

order, chaos, randomness, predeterminism, etc.

Yadda yadda yadda this video is interesting and tickles the brain.

Apparently this stuff is “Hot Ice” or sodium acetate.
I dunno why people don’t put descriptions with these goddamn confusing gifs. Drive a brother nuts…

OKAY SO CHECK IT. I’M ABOUT TO THROW DOWN SOME HARDCORE SCIENCE AT YOU. 
Up there ^^^ is a phase diagram for water. What a phase diagram basically does is show you how the relationship of pressure (on the y-axis) and temperature (on the x-axis) affects the phases of any substance. Now the phase diagram for water seems pretty standard. At low temps and higher pressures, it’s solid (ice); at moderate temps and higher pressures, it’s liquid (water); and at high temps and low pressure, it’s gas.
However, check out the line b/ween the ice and water phases. That line is called water’s fusion curve. All along that line are various pairs of temperatures and pressures at which water starts freezing and ice starts melting. All seems well and good until you realize, wait, why does that curve have a negative slope. Almost every other substance has a positively sloped fusion curve. And that should make sense- at higher pressures, you’d expect molecules to be squeezed together, thus, making the substance more solid. 
Water totally defies that logic. At higher pressures, ice actually liquefies at lower and lower temperatures. Now you may ask, what does that even mean? Like irl ? ? ?
Yo, that means some pretty radical stuff, actually. 
When you go ice skating, you’re wearing these crazy as heck shoes on top of razor thin blades- your entire body weight on two pieces of metal millimeters wide. That creates crazy amounts of pressure on the bottom of those blades! ! ! So when you get on the ice, you’re pushing down on that ice with ridic amount of pressure, so what happens? Yaaas, you got it- it L I Q U E F I E S. When you’re on the ice, you’re actually gliding on thin layers of liquid water. With that layer of water between you and the ice, there is little to no friction- that’s what makes ice so slippery! So the next time you slip on ice and fall on your face, you have water’s weird-ass fusion curve to blame. 

This is really interesting, but scientists still aren’t sure why ice is slippery. You can’t go around acting like we’ve got this shit on lock, yo.

So I guess this is what dying feels like.

The gender binary is true. The data in this book is outdated. Males and females DO in fact have brain differences. Several studies done in the late 2000’s and early 2010’s point this out.
There is a Norwegian documentary which points out the flaws and problems with the approach in this book and a lot of earlier studies.
In an attempt to enforce political correctness, biological differences in the equality debate are often belittled or put aside entirely. Nature decided sexual dimorphism was advantageous to our survival. We cannot ignore this and decide to wear blinders.
Just to cover my ass: I’m by no means sexist or gender biased and support personality development and equal opportunities regardless of gender, race, or sexual preference. But stop pretending we are all the same.
Studies have shown that the AVERAGE intelligence of both genders is the same. However, men have a larger variance, i.e. there are more extremely stupid men and more extremely smart men than women. Men have a shorter lifespan because they expend more overall energy (even on a cell-biological level) on competing for a mate - there are theories that men are nature’s evolutionary laboratory, which means they remain on average the same as women, but the VARIANCE in phenotypes is greater.
This also explains why facial/body symmetry is often more pronounced in females than in males.

^ Interesting and valuable comment. Two sides (or more) to every story.

take a moment to realize you have never seen your face in person, just reflections and pictures

some scientists agree that if you saw a clone of yourself, you wouldn’t recognise it as you, because our idea of what we look like is so different from what we actually look like

This gave me anxiety

"Some scientists…" pshh. Bullshit. There’s no way I wouldn’t recognize myself. I look in the mirror so friggin’ much it’s only slightly funny.

This is a very cool way of visualizing the conversion from Cartesian to polar coordinates. Credit goes to Reddit user mikef22, for showing me this method.
Wait… What’s going on?
I know, it looks like black magic. I’ll explain.
First, you need to reflect your function along the line y = x, shown here as an equivalent rotation. This step is necessary because we arbitrarily defined zero degrees at the right. If the convention had been with zero at the top, we wouldn’t need this step.
Once our curve is in place, bend the Y axis around and contract it into a point. The result is the polar graph!
Now, that step is a bit harder to understand. The idea here is that a straight line can be considered (geometrically) as a circle of infinite radius. In a way, it “never curves on itself”.
By bringing the radius from infinity to zero, we turn the Y axis into a circle, which is contracted into a point once the radius reaches zero.
Pretty cool, huh?

what the fuck(I’ll get it… eventually…)
