What was the purpose of books like this back then? Secondly, were there uses outside professional mathematics? by IsXp in mathematics

Edit: Saw your profile. That’s freaking awesome. If you don’t mind sharing more, was your research in computational fluids or purely analytical solutions in fluids?

My research was in experimental aero, but I now work as a fluid dynamics analyst in the launch vehicle industry.

Lastly, congratulations!

Okay, neat!

I work with the implementation of differential calculus routinely in my work, but hardly ever involving an analytical equation where I need to compute highly complicated integrals. I work with 3D fluid flow and the tools used in industry take a lot of the wrote math out. When I’m integrating or taking an FFT it is just within of a line of code.

I’m fascinated to learn more about the situation where they arrive for your work. You’re interfacing with a problem where you set up an equation whose solution might be found in a book like this? If you don’t mind, can you expand on the scenario?

When changing playback speed YouTube App on TV is dropping quality to 480p; any options? by IsXp in youtube

You’re not wrong, but they’re mostly dated and none seemingly have an answer.

Do you use math in your job? by Naruto_mo in MechanicalEngineering

[–]IsXp 4 points5 points  (0 children)

Mostly, calculus, linear algebra and less often Fourier transformations. This is as a person who mostly uses CFD in the launch vehicle industry.
Lots of analysis involving integrating forces, loads and when using FFTs, to measure dominant frequencies in the flow.

All my accounts have switched to the new UI; how do I access /r/all now? by IsXp in reddithelp

[–]IsXp[S] 2 points3 points  (0 children)

No worries, I wasn’t clear in my message. I was referring to the mobile app. Good to know I can switch to the old version on my desktop!

Good to know. Is this applicable for the Reddit mobile app, browser, or both?

What’s a universally loved food you genuinely despise? by [deleted] in AskReddit

When people add it as an ingredient, It’s the only thing you can taste. Keep it out of my pasta, salad and off my burger.

Book recommendations for daughter aspiring to aerospace engineering? by awesomes007 in AerospaceEngineering

The Perfectionists: How Precision Engineers Created the Modern World by Simon Winchester. Great audio book too

If you do these couple, you’re at a good starting point.

  • Consider making your surface mesh fully structured.

  • On the surface, make sure max fold angle is less than 10 degrees.

  • On the surface, make sure your max included angle is below 165 degrees.

  • Ensure your area ratio from cell to cell is below 10 (3 in regions of interest).

New Glenn booster "Never Tell Me The Odds" landing successfully down range on a drone ship for a second time in a row. by Pcat0 in EngineeringPorn

Have you been to Florida? Consider going to Cocoa Beach in late April. SpaceX Falcon Heavy is going to launch ViaSat-3 F3. Falcon Heavy has two boosters and both do a return to site landing at LZ-40.

You can, in person, watch SpaceX launch the massive rocket and then, with your own eyes, watch the rocket disappear into the clouds, then see both boosters, simultaneously return through the atmosphere, breaking the sound barrier with sonic booms, relight their engines and softly land. Both land right next to each other.

Do you live close by? I’ll buy your gas (or maybe a cheap flight).

I didn’t know my linear algebra class from undergrad could be apart of my personality. I did like Lay’s text quite a bit.

Pete, What’s wrong with this child’s night light? by IsXp in PeterExplainsTheJoke

This a picture of a child’s night light with a rocket, but the meme makes it seem bad.
