Oh, and if you're curious about the animation's meaning, check out the report here: https://tinyurl.com/v9vevqx It's curious to look at everything I would've done differently (a.k.a. the /formatting/), but it's also nice to see how much I'd do the same. Guess I haven't changed much!

I've said it before, but the SIST program (https://diversity.fnal.gov/sist/ ) was the gateway by which I could dedicate myself professionally to science. Do research in undergrad, and then pay it forward by hosting junior scientists as you climb up the career ladder!

Got a nice surprise today from Google Scholar—the first scientific document I ever wrote, a technical report on accelerator instabilities for
@Fermilab's SIST program, got cited! It was also the first time I ever made a scientific animation. Look at that thermal instability go!pic.twitter.com/KAAGn3Wmp5Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
You can get a sense of what nonlinearity does to the hopping "rules" by looking at where a dense group of points go after about ~15 hops forward/backward for varying k. (This is technically HW for
@stevenstrogatz's dynamical systems course—it's tough to hand in a GIF in person!)pic.twitter.com/ifAv64c87zPrikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
The homoclinic tangle itself is made up of all the points that eventually approach (1,0) as they hop, and the ones that eventually approach (1,0) if they had started hopping in reverse.
#mathematics Here's what it (approximately) looks like. Weird, isn't it?pic.twitter.com/kAIcRNgkER

Eventually, they'll all fly out to infinity, but at differing times; and how/when that occurs is very sensitive to their starting points. That's called transient chaos! It's all thanks to the "rule" causing those goofy patterns near (1,0)—that's (part of) the eponymous tangle.

Another class-inspired animation; meet the homoclinic tangle! A rainbow of closely packed points hop on the plane according to a simple rule. As they hop, they spread out, and their hopping patterns get more & more different to their neighbors'—a classic symptom of chaos.

Today's asymptotics class inspired this wonderful example of Carrier's rule; "divergent series converge faster than convergent series because they don't have to converge."

A question I answered made the network "hot" list on StackExchange, so in case you're wondering—here's why the stream of water from your sink gets narrower as it falls (and I make a solid prediction for the shape, IMO!)

Here's how dust particles in a liquid like water react to an object steadily moving within that fluid. Amazingly, this behavior is universal—*any* object inside a water-like fluid will cause this disturbance in regions far from the object as it moves!

@Cornell undergraduates, if you're interested in designing, constructing, and presenting#scicomm exhibits for the Physics Bus (@Physicsbus) please check out PHYS 4500 this Spring!@CornellPhysicshttps://www.youtube.com/watch?v=Q3moS3dZq70&t=1s …Prikaži ovu nitHvala.

Now that summer's coming "soon", I have a moral obligation to tell any undergrads looking for research internships to visit this site: https://www.pathwaystoscience.org/ It was responsible for 3/4 internships I did as an undergrad—I can't tell you how invaluable it is!

It’s very bitter this time around to leave Puerto Rico for the new semester—especially since I’m leaving friends & family to deal with the horrible earthquakes on the island these last few days. Please consider donating to local aid orgs; we need all the help we can get.pic.twitter.com/qSMKN0unBA

6+ months of writing and a slim-ish textbook later, my Commentary on Fluid Mechanics is finally done. I'm happy I got the opportunity to share my perspective on intro fluid mechanics, and hopefully future students/enthusiasts find it helpful! https://wp.me/p7zu73-18Q

Today is bittersweet; after a long day of answering questions, my last office hours for introductory fluid mechanics are over! I had such a blast this semester teaching my students about fluids and how things move—I can’t wait for my next teaching adventure.pic.twitter.com/W4dgq4lX65 – mjesto: Thurston Hall

Some neat science—the "blink" in the droplet is a chemical compound losing its electrons. Over time, it'll slowly get them back, and suddenly lose them again! (The droplet is about as big as a mote of dust.)

This week, I'm talking about flow near immersed objects. Nearly no one talks about why all those crazy paradoxes show up for creeping flow in intro fluids, so I address it here—it's all about the flow at infinity!

The video is choppy and faint, but I finally spotted an oxidation wave in a tube the size of a human hair! I hadn't seen it in other tubes, so I was scared I was losing it in the noise—turns out the other tubes' chemistry was suppressing the reaction. Boo hydrocarbons
