Wow, every time I see this site I am blown away by how well it is done. I am going to put a couple of book titles out there in case somebody doesn't know about them and could benefit: 1.) "The NURBS book" -- Anybody got this

My mistake then. I did not intend to try and be so precise. I was thinking loosely. I have a very simple autodiff tool hand rolled (in Python) here to play with. I raise 0 to a negative exponent in the gradient of the cube root at 0.

This is really a nice thing to put out there. I want to add that AD (automatic differentiation) can be a great jumping off point to other things. (It sure was for me in my studies anyway) Here is the path I followed (though I am sure th

The differentiation of a fractional power (fraction less than 1.) involves a negative fractional power. 0 raised to some negative power involves dividing by zero. This gives you some kind of NAN in, e.g., vanilla languages such as Python.

Fair enough. And yep, I plan to find a chink in the ol' armor somewhere. Just get me 20% time thinking physics at work and I will be happy... (even if it we never "get there" with the device) Or more likely my insatiable ap

Are there Quantum Applications & SDK positions open? I am planning to apply within the week. (PhD engineering - optimization for my thesis, lots of hydrodynamics at school and work. I started life in aerospace incidentally) Also, I&#

How about the going the other way? I'm an engineer (hydrodynamics and optimization, and econometrics way back before all that.. and.. aerospace before that) who just finished a PhD and who has been writing software professionally for

My take on miniKanren is that it's implementation is designed to be small and hackable. Especially small with microKanren. If you don't know scheme/lisp, but want to roll your own for educational purposes, then check this

quantamagazine did a nice write up on Michael Atiyah back in 2016. They rightly brought it back to the font page. Here is a link: https://www.quantamagazine.org/michael-atiyahs-mathematical-...

Did I mention that I was running mint as well? With 2012 macbook pro hardware.

Wow - that is interesting to hear. Let me toss in a caveat by saying that I had 2 different multi-monitor setups that I transferred between while running straight off the machine quite often as well. Typically problems would crop up after

Yep. I've been running dual boot OSX/mint for some time and god the hardware has never been happy about it. Especially with regard to the GPU and multi-monitor support but I suspect also with regard to battery usage and other po

Since this is trending, you might be interested in the responses from the Austrians themselves: https://mises.org/wire/caplan-and-responses Note Caplan replies to some of this and it's linked in the same place. R

Thanks for bringing this to my attention! I've been very interested in the work the "Geometry Collective" is putting out there (discrete exterior calculus and related applications). Nice to see a course covering these funda

What approaches to develop-ability are you looking at?

by tobmlt 8y ago
Thanks a lot! It would be cool to have some of it get used! I've been trying to get all of it online. Right now there is not really anything coherent ready to put up yet - a smattering of Jupyter demos using/explaining aspects

I've recently completed my PhD in the automated design/generation of constrained ship hull form geometry. This is a method that originated in the 90s for generating the basic geometry of a ship from "scratch" - well act

Gerard ’t Hooft goes here too I think: http://www.goodtheorist.science/ Though I think Susskind's lectures and books are truly the best starting point for say, an engineer who wants to go back and do physics from the

Well, here you are defending the way you expressed your personal reaction to the book. Your reaction itself is of course fine. -But earlier you expressed your reaction to the book as if your particular experience of it were an absolute tr

Do us a favor and delete your comment. This kind of talk can discourage and embarrass people who would otherwise be focused on learning. Just link to the book, which is good, and save us your little puffing yourself up bit. I am sorry but

Really? That's kind of interesting. I find the language completely charming. With this quote it could be because "fifth-form" has no resonance at all with me outside of the text, or maybe I vaguely recall some novel of Fit

Chiming in anecdotally here: 50k ``real'' lines of Python and climbing. No problems maintaining it but I wrote it all for my dissertation. It's scientific/CAGD programming, -Not sure but it feels like that makes it ea

Some are just searching for anything that will generate the plot they want with ``better'' workflow. It's subjective. TikZ can be off putting, if you don't want to put the time in, or it doesn't meet some particul

I can't say I like the grandparents "robotic" tone, but I have to disagree with you here on what all is required for coordinated efforts. People disagree locally on norms and etiquette all the time precisely because we are n

In vanilla QM, time is Newtonian - taken as a given, independent variable. You can "tack on time dependence" as it were. (Special) relativistic QM becomes quantum field theory (well, first Schrodinger's eq becomes the Klein
