anyone have any ps3 game recs. . .

[fandomchaosposts]

when my class starts looking a lot like it's common sense and I don't need to revise

[blondiest]

whenever i have something to add to someone's post i get hives. it's always like haha feel free to kill me in cold blood if that was annoying i will totally understand

[enhanced-operatives-division]

Btw if anyone needs references for anything in game because they can't play them I'm okay with grabbing screenshots or getting clips if you send an ask or something

What have I been up to? Well more or less more optics.

I started to learn about the Index Ellipsoid, and I am beginning to understand how we can quantify a materials allowed polarizations using the "indicatrix" (not going to lie this is a hard word to spell lol)

I now understand that there are two possible electric flux densities (basically the quadratic equations +/- gives two roots, so when you solve for two possible refractive indices, you also get two D solutions) and that these two fluxes are orthogonal.

The index Ellipsoid let's us characterize anisotropic crystals into biaxial (two defined optical axes) and uniaxial (two axes are equal)

But honestly, I'm hitting a bit of a wall here. I just want to be familiar with the material before grad school starts. Since I'm self studying now, I decided to venture off into a related topic: Computational electromagnetics!!

I took numerical methods this winter so when I heard about Finite Difference Method I didn't look like a 🦌 staring at 🚗 lol (honestly I find Runge-Kutta methods scarier haha)

So I learned a bit about collocated grids, recalled Dirichlet boundary conditions, periodic boundary conditions as well as Neuman boundary conditions.

My plan is to use COMSOL multi physics to do a little simulation for my masters thesis, so I'm betting that having a grasp on the numerical side of emag is something I need to accomplish to bear fruitful results.

And of course I get hit with the realization exactly *why* plane waves are used to teach us optics: because they are simply a stepping stone towards us learning about Gaussian Beams!

The 🐇 hole just keeps getting deeper and deeper... 🕳️

found THEE original matthalle moment, which is surprisingly in the channel i have for notes on ‘i want to hold you (hostage)’ (at the time it was called ‘fuck the war. they are in love.’ after the line from gravity's rainbow. which i haven't read) tbh i thought it would have been in the channel for my notes on ‘there's nothing i hate more than what i can't have’

The Marangoni Effect

Also known as the Gibbs-Marangoni effect, the thermocapillary effect, and thermocapillary convection, the Marangoni effect occurs at interfaces with surface tension differences, often between liquid and gaseous phases. It can be defined as "the mass transfer along an interface between two phases due to a gradient of the surface tension." Often, this gradient is due to temperature differences, hence the term thermocapillary, but this is not a requirement of the Marangonie effect itself. Other terms, such as solutocapillary effect, are less commonly used when the effect is driven by concentration, instead of temperature. The Maragoni effect applies to soap films, the processing of silicon wafers, electron beam melting of metals, and, in everyday life, the formation of "tears of wine" in a wine glass.

yeah it's great that your wife is having a baby and i'm really happy for you but you also are sitting on a COMSOL model that i need desperately so if you could ignore your newborn and send me those new EM loads that would be great. thanks.

[kremlin]

wow i would sure not be having any serious issues finding cracks for current versions of comsol, abaqus and ansys right now if all my eastern european male rat internet friends weren't all killing each other right now

[pigswithwings]

QUICK. FAVOEITE GAMING COMSOLE EVAR ?

UHHH UHH UMM FUCK UHHH WII U I LOVE HER

[blondiest]

have officially spent 4 hours on a task that COMSOL ryan said should take 30 minutes 😎

[necarion]

I get the impression software companies like MATLAB and COMSOL don't care much about cracked versions. They aren't going to get money from individuals who are using them, who couldn't afford thousands of dollars. But if those individuals as their companies to use software with which they're familiar, companies who cannot get away with cracked versions...

a week ago i (full of hubris) thought to myself. you know, this modeling (<- the multiphysics kind u_u) shit is not so bad. maybe i have gotten good at it. and now something fundamentally sinister is occurring with my fucking model and i'm going insane trying to troubleshoot. COMSOL i did not fucking miss you. bitch
