| Thanks for posting this, Sander. There are other examples of bit hacks and I have always wondered whether others are out there waiting to be discovered. Here there is the possibility of long range effects due to carrying. More wild possibilities... |
| Looks like a great book. About (iii), I see from the table of contents that this is a big book. To learn Wolfram Language, you are probably not suggesting to read the whole book, but it is enough to do chapters 1-3 (and maybe skip part of 3). ... |
| I think the problem is that, if you were doing this with tensor operations only, is that you would need a contraction operation akin to Diagonal. It seems like the syntax (currently allowed) for [PartLayer][1] is insufficient for this. Take the... |
| Recently I decided to work on some of my own projects, and so I left Wolfram Research after almost 17 years. I still have some time on the side to do some consulting if anyone needs a consultant for a project involving Wolfram technologies. ... |
| Ok, there is a lot to say here, but I should first of all say that I am not really an expert. I think that there has been some implementation of nonstandard analysis in the Wolfram language, although I cannot remember where. About using Wolfram... |
| What do you think of the idea of automatically judging if a piece of data was beautiful? This could mean the data in an image (ImageData) or maybe the result of a computation (e.g. CellularAutomaton), or anything, although I am thinking of a list or... |
| Thanks everyone. I woke up in the middle of the night realizing that `NotebookImport[Notebook[AllCases[expr,_Cell]]` would work. Only learned about NotebookImport a few days ago although it's been around for a couple years. |
| According to the documentation, the arguments are supposed to be real numbers. That means Reals in Wolfram Language. If you give it integers or rationals (like your code is doing) the documentation says it tries to give an exact rational result. ... |
| While I don't know why it is designed like this, here are a few possible reasons: 1) The solving algorithms have to be as general as possible (not just quadratic). 2) It would be possible to add an extra layer of code checking for cases where... |
| Thanks Sander. I guess there are two competing things going on, adding paths to give the electrons more choices and making the paths longer for the electrons. Does anyone know how this calculation matches up with a physics-style sum of paths... |
