Despite my last entry clearly dictating that I have no idea what's going on when it comes to fluid dynamics, here I go again.
This time, it's droplets of water and propylene glycol and how they interact when on a glass surface.
First, watch https://www.youtube.com/watch?v=K8Wx2PHIYGI. Now. Okay, watched it? No? Then the rest of this won't make much sense and will be pretty boring. I promise it's cool, and the music's pretty sweet too.
Now that you've all either watched it or closed out
Cytherean mountains (AKA mountans on planet Venus) cannot be seen directly. The surface of our sister planet is completely obscured by the thick clouds that also heat the surface to a balmy 900 or so degrees Fahrenheit. So, how do we know that the mountains are there?
Fluids, of course! (dear god why)
To put it simply (seeing as I can't make it more complicated if I wanted) the atmosphere of Venus is more like an ocean than a conventional Earth-like atmosphere, with a hotter under layer an
Yup, that's a pretty terrifying title. And yes, that's exactly what this is.
Tell me that I could name this anything different. Biomedical Engineering at it's most amusingly accessible right here!
So, what's physics-y about this? Apart from, you know, everything in existence being physics. First of all: magnets. These things are "remote controlled" by magnets and magnetic fields. You know, those things that you can't see but you have to contort your hands to figure out which direction

For those of you not constantly checking up on astrophysics and stuff like that (not a common habit of most people), the cosmic web is a construct that binds together the majority of the universe that has been long theorized, but never imaged. Until now, that is.
The cosmic web is made up of around 84% dark matter, which is why it is so difficult to find and photograph. As you could imagine, dark matter is invisible to us and any instruments we have except for its interactions via g
Yes, this is totally a physics post, and not just an excuse to post this gif
This is Waffles the cat. And his job is to remind us all about winter driving. As any of us who have been behind the wheel on a snowy day know, the coefficient of friction between regular tires and the snowy road is veeeery low. Dangerously so. Just around .15, compared to around .7 on a dry road. Even with snow tires, it can still be hard to stop due to low coefficients of both rolling and sliding friction.
Moral
I think that the way this was originally sent to me conveys the meaning better than any rewording I could do:
Equation of orbit of a small mass around a much greater mass
Equation of human awe of earth orbit
So now that you've watched it, you should have a greater appreciation of gravitational forces and centripetal ones, the whole Fc=mv2/r and Fg=GM1M2/r2 and such.
Or maybe you just affirmed that space is really freaking awesome, and a lot prettier than anyone gives it credit
"Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, without the gorgeous trappings of painting or music." —Betrand Russell
Physics is, in essence, applied mathematics. It's how math applies to life, and the results thereof. And math is... beauty? That's not how one would usually think. However, there is a certain beauty to math and how everything resolves itself when it is applied. The way tree growth and snowflakes resemble fractals, light
If you guys happen to look at nearly anything nerdy, you have likely seen the original video for this or a reaction to it.
In essence, a
came out trying to prove to the general public how 1+2+3+4+... all the way to infinity equals -1/12. You know the drill. Go on, watch it. I'll still be here when you get back. Or at least my post will
"So what?" you're probably asking. Or maybe you do know the so what, who am I to judge? Anyway. If you don't believe the video and think it's all stupid,
