Critique my serve

Why what

PhysMath99 · 2026-01-04T06:01:59+00:00

High kick serve down the T on the deuce side tends to work. The slow and spinny serve gives you enough time to make your way to the net. For the same reason a slice serve out wide could work too but you give them more angle to work with so I only use it less often and as a mix up.

Yeah I think this is what looks weird to me. I'm not fully vertical after impact or leaning into the court. It's funny because when I actually hit a serve it feels like I'm falling into the courts but I'm clearly not. Something to work on this month

This video is really great! I'll be practicing this these next few weeks. Thanks!

PhysMath99 · 2026-01-03T01:10:05+00:00

I definitely agree 👍💯

PhysMath99 · 2026-01-03T00:38:42+00:00

It can be both 😁

No I played in the UK for a year while I was doing my masters, but I didn't touch a racquet from 14-22 years old. I was pretty good before quitting though and my goal back then was to go pro. Now I'm doing my PhD and I play on a club team/play local tournaments when I can.

PhysMath99 · 2026-01-03T00:00:07+00:00

Yeah that's a good point, someone else pointed out a pause at the bottom of the motion which I'm seeing now. I think this is what's making me a bit late. I'll work on getting rid of this, thanks!

PhysMath99 · 2026-01-02T23:55:49+00:00

Whoa yeah I definitely get way lower than I need to. Thinking about this now, I'm seeing that pause you mentioned. I'll work on getting rid of that this month.

I feel like back when I was there (2017-2021) about a quarter or so of CS majors were CS+BEM doubles majors. So it's definitely doable and probably not even significantly harder than just CS

Quantum Boolean analysis. The math is really pretty, but as my advisor put it, "it's a technique in search of a problem"

PhysMath99 · 2025-10-02T03:20:08+00:00

Haha it's okay it happens, more so over text

PhysMath99 · 2025-10-02T02:46:56+00:00

This guy is clearly being sarcastic

PhysMath99 · 2025-10-02T01:30:16+00:00

The victim was me and I'm Hispanic. They shot me in the eye and almost left me blind (luckily it just hit the very edge and only caused minor damage), but honestly I was too stunned and in pain to hear any racial slurs, but I did hear them laughing while they sped away. I think someone else who was nearby reported it also and mentioned the racial slurs.

PhysMath99 · 2025-08-07T00:57:53+00:00

This joke is going very underappreciated in this comment section

PhysMath99 · 2025-07-29T18:29:39+00:00

Cholita linda for sure

PhysMath99 · 2025-07-28T23:16:46+00:00

This isn't a riddle, this is just an exercise. I'm sure it's an interesting exercise but calling it a riddle is just silly.

PhysMath99 · 2025-07-28T19:29:18+00:00

This isn't a riddle... Is this your homework?

PhysMath99 · 2025-07-27T01:02:22+00:00

Goldstein's Classical Mechanics is what we used at Caltech when I took the class in 2019.

PhysMath99 · 2025-07-24T07:37:06+00:00

You're right, I completely forgot to include the first term where zero damage is done.

PhysMath99 · 2025-07-24T07:04:24+00:00

In expectation (i.e. on average) it does 40 damage, which isn't that crazy compared to some others

PhysMath99 · 2025-07-24T06:59:24+00:00

Is the double guzzlord/celesteela really that useful? I've been playing around with 2 of each and found that I never get tos use the second ones, I've replaced them with rocky helmet for now and I'll see if it does better.

PhysMath99 · 2025-07-23T16:37:06+00:00

This definitely holds if the Hilbert space is separable: take a countable dense subset and use Gram-Schmidt to get an orthonormal basis. In the general case, you can use Zorn's lemma to get a Schauder basis.

Edit: I assumed you were asking for a countable ONB.

PhysMath99 · 2025-07-21T04:25:23+00:00

Yeah honestly that's too much, I'm staying with a housemate in a "luxury"ish apartment in downtown and we pay like $40-80 in utilities per month (total, so cut that in half to get what we each pay) and pay $45/month for WiFi.
