Dat shrug when you fkin own space in someone else's mind...i wouldn't want to go against me either 😱

"Of the 431 Class of 2021 @RoseHulman graduates, 426 have been placed within six months of graduation, with an average starting salary of $73,800 and a high reported offer of $145,000. That’s a 99% placement rate." JFC, economically, i choose the entirely wrong path...

For the high roller, I am going to assume a CS/SE/math, and likely FAANG. So, $150k in SF is probably reasonable for a newly minted BS degree(s)? If the job is remote, then the salary is woah...

In this simulation (not from my group, but from Venkat Raman's group at U. Michigan) you'll see a detonation propagate through layers of reactive mixture. youtu.be/XPzs5Z249Hs

BREAKING: Senator @tedcruz bashes world renowned @MIT stating: "Just because it’s MIT doesn’t mean it’s good. I’ll bet my thoroughbred [Heidi] that any TX prof. can beat an MIT prof. at bull riding. Dunkin donuts and lobster rolls can't save those hacks. God bless Texas."

RUBBER DUCKY ALERT🐤🐤🐤🐤🐤🐤🐤🐤: Stuart Laurence's group at @UofMaryland produces some of the highest quality #schlieren data I have seen. He might be taking requests. Email at hypersoniceverydayobjects@gmail.com. Funded in part by @NSF.

This is 💯 a topic @RandPaul would debate. Have you seen his stance on NSF spending? c-span.org/video/?512047-6/s…

Equations are destroying our youth...keep them out of your powerpoint presentations
Great find! There are many great Iranian fluid mechanicians.

I am working on "high speed and high temperature past a surface undergoing pyrolysis/ablation" and one of the best papers i have encountered is from Iran.

To the U.S. `I have a PhD’ in high-speed aerodynamics community, underestimating the capability of foreign powers is foolish.

A wise professor once told me [while I was in the midst of defending my dissertation on high-speed flows], that if you think you’ve solved something new in compressible, high-speed, hypersonic flow, it has almost certainly been pub. in Russian 30, 40, 50 yrs ago. He was right..

BREAKING: Senator @tedcruz bashes children's book for throwing up equations without any context. The #Texas #Senator states: "This is a terrible children's book. The lazy author is using intimidation tactics to look smart. They don't understand well enough to explain simply."

Huh??? “The challenges of hypersonic flight aren’t different from those of lower supersonic flight, they’re just way worse.” Hypersonic BLs ARE sensitive to different disturbances compared to their subsonic and moderate-supersonic counterparts. annualreviews.org/doi/abs/10…

Hypersonic is an often misunderstood word, and for good reason. Achieving hypersonic speeds is tough, but it's not all that special... and it certainly isn't new. sandboxx.us/blog/its-a-myth-…

The appearance of these new instabilities are only possible at high Mach number (M\gtrsim 4 to 5) and they are the dominant precursors to the transition-to-turbulence process in quiet [even noisy] wind tunnels.

Exponential growth??? really???? "The air resistance experienced by a vehicle increases in proportion to its velocity squared. This means that as the speed of the vehicle increases, the pressure and friction its subjected to don’t increase gradually, but exponentially."

If drag grew exponentially with velocity, we would be in a world of shit.

So my long-accepted article on fluid mixing is finally out! But not only that, it was chosen as one of the Editors' Suggestions and featured in @APSphysics physics.aps.org/articles/v15…! Check out the full article here: journals.aps.org/prfluids/ab… Thank you so much @PhysRevFluids!
Effectively Mixing Two Fluids

Effectively Mixing Two Fluids

Want to mix two fluids? Researchers have developed a path to optimize the stirrer shape and velocity to give the best outcome.
