 Jan31 comment Permanently rounding numbers/values to a given number of significant figures I must say the way you have staged your question it means that nearly every system has problems, as you would need to use fixed point arithmetic. Jan15 comment Turn list of rules from radians to degrees, match all greek letters Thanks i got some ideas to finish my job turns out you terraced me 2 new things Jan15 comment Turn list of rules from radians to degrees, match all greek letters Its no problem. No one longer going to calculate anything with it. Students are just using it to tabulate answers for themselves to measure real things and see how their solution matches reality. Jan15 comment Turn list of rules from radians to degrees, match all greek letters ah that's quite well done. Ill wait a bit if you dont mind, if somebody is even better answer but i think this is it. Jan15 comment Turn list of rules from radians to degrees, match all greek letters Thank youthat helps i ended up to this myself: Replace[a, Table[Rule[greek, x_] -> Rule[greek, x 180/Pi "\[Degree]"], {greek, {\[Alpha], \[Beta], \[Gamma]}}], 1] Sep6 comment Grid snap for drawing tools @Öskå Maybe, drawing tools would be pretty competent for this particular case if it had snap to grid, when not its a bit painful and useless tool. Idea that these are sketches before any calculation. Preference is NO code it scares the lower 2/3 of students away. Aug5 comment Why is Query so much slower than Part? could it be that querry is a O(n) algorithm where part is O(1) algorithm. Because the name implies that querry must scan the elements for testing. Sure it should optimize for set reductions but it does not do so yet. just speculating. Jul23 comment Mathematica 10 fails to calculate integral that Mathematica 9 can handle Didnr mathematica10 get a new update system could that be doing work in the background Jul23 comment Embed Code Into Image it would be more natural for this data to be just a comment in the metadata section in the beginning of the eps. Jul18 comment Mathematica 10 Notebook Fonts Look Bad try changing the font, ive noticed that some fonts react badly in mathematica including some of the default fonts. Jul18 comment Software for effectively modeling gears Adams, simpack, open modellica, simulink... for other software. Jul17 comment Software for effectively modeling gears Could you clarify what aspect of the gears you want to model? Ideal physical behaviour, contact, vibration... Note all of it basically means do my PhD for me. Jul17 comment Mathematica 10 Notebook Fonts Look Bad windows uses its own hinting engine and it may or may not be configured properly. It certaibly wont match linux. Jul5 comment 256 Shades of Grey @DumpsterDoofus the dither isnt entirely centered you should probably use Image[Table[ x + RandomReal[{-1/256, 2/256} ], {y, 1, 250}, {x, 30/256, 40/256, 0.02/256}]] Jul5 comment 256 Shades of Grey @george2079 Done Jul5 comment 256 Shades of Grey add a bit hue to your black so its say slightly blue (Cool) or yellow (Warm) then inyerpolate that to white and you sudddenly have far more colors to play with. Pretty standard way to handle banding. or add a bit of noise. Jun29 comment How to get shadows in Graphics3D? @AlexeyPopkov its not because i havent had time searching for the matrix plot uses. I just quikly eyballed the result. you can change the focal view to any angle now its 20 degrees. But im not really good with all mathematica functions. Much better at rendering stuff. Jun29 comment How to get shadows in Graphics3D? @AlexeyPopkov Sure pastebin.com/4Lmnbk7T you need the test rib generated in the same folder. For heavens sake dont run anything from desktop. Let me know if you have problems. Jun26 comment String templating Yeah, thats good since at the moment it is a bit painfull to do these. Jun26 comment String templating Yes its better than mine. But despite the cryptic nature, cubas idea has the nice feature that the string is totally separate form the actualizing code, and its just one string. This means its much more trivial to change by any other end user and code shared between different templates. I need to meditate on the answers a bit before deciding.
