I liked "Godels Theorem Simplified". Although it looks like it is now a lot more expensive than it used to be. Maybe get it through and interlibrary loan. https://www.amazon.com/Godels-Theorem-Simplified-Harry-Ge

It would be interesting to see how things compared with set operations on hash table keys and `sort`.

The parent article is about 99% fluff, but for people interested in Philosophy of Science, John D. Norton (from the article) has a treasure trove of interesting stuff. https://web-beta.archive.org/web/20120702103247&#x2

Thanks for the find. I want to cramp about 100 of these as close together as possible.

Speaking of LEDs, I've been on and off looking for 0402 or 0603 pink LEDs. There seem to have been multiple manufacturers building them years ago, but it seems like they've been discontinued/obsolete. Now I can't seem

I'm just a newbie when it comes to 3D modeling. I've never used SketchUp, so I don't know how they compare in complexity, but FreeCAD does have quite a wide assortment of "snapping" features: http://www.

Can you briefly outline what features of SketchUp you like best? Have you looked at FreeCAD?

This article seems a little light on details, and the original paper (not behind a paywall!) is quite dense, but some of my favorite paper's on Maxwell's demon are: http://www2.pitt.edu/~jdnorton/papers/E

I'll jump in to emphasize the notion. I've recently decided to try and pick up 3D modeling using FreeCAD, and I thought I'd try my hand at watching some tutorials on YouTube. Well I lucked into a great beginners series: ht

You can create some pretty high frequency transistors (BJTs) with Indium Phosphide (InP) (ft > 600GHz, fmax > 1THz). See page 33 of: http://www.ece.ucsb.edu/Faculty/rodwell/publications_and_pre... ...for ex

Getting completely off topic here, but I found it interesting that there were only 27 actual PDF files in the first 10 pages of search results using "allinurl:.pdf". So I tried using "filetype:pdf", and none of the firs
