This is really nice. Congratulations on the contributor badge. Here is a similar idea. [ONE MIT 2018][1] and [ONE MIT 2020][2] In this example, we printed about 3 10 ^5 names on a six-inch silicon wafer. I used different font faces to make...
Each new release of Mathematica has functions that I should be using in my regular workflow. The problem is that I develop habits--and when in a hurry (which is the usual case), I fall back on those old habits. Many of these of my go-to...
This has been answered in [StackExchange][1] There are several solutions, but [@Carl Woll][at0] 's is the easiest to implement: CellMargins->AbsoluteCurrentValue[ ...
Those of you who just scroll to the bottom of a thread (like me)---please see the updated info in George Woodrow III's original post. And, thank you George.
Hello I am afraid I missed the Sept. 22 deadline to register for the technology conference. This is the first year I have been able to go in a while because it is virtual. There doesn't appear to be a way to register late--am I out of luck?
I would guess that that the problem is with the stylesheet here. Just a guess. Try to change the stylesheet to the Default and see if the problem persists (Format>Stylesheets). Or, take a look at the Option Inspector (Format>Option Inspector)...
Perhaps your syntax is incorrect. The documentation is a reliable friend. ls = 50/(s^3 + 2 s^2 + s + 4) tf = TransferFunctionModel[{{ls}}, s] NyquistPlot[tf] Solve[0 == 1/ls, s]
It is not quite clear to me what you are asking. (first, your syntax is a bit off. You probably want to use a symbol for the lhs, not Grad (f).). A gradient is a vector. When you say "smallest", do you smallest magnitude? And, assuming the...
Try DensityPlot3D. The Documentation is your reliable friend. [DensityPlot3D][1] [1]: https://reference.wolfram.com/language/ref/DensityPlot3D.html
I tried Ulrich Neumann's suggestion of the stackexchange link you gave and it works just fine. To be explicit: Vpot[p_, r_] := Piecewise[{{p[r]^2/(4*Pi), p[r] = 109/ 250}, {(86031603 + 640*Pi*(217 -...
