Hans, do you have a notebook that illustrates the use of your quaternions package? Also, how fully symbolic is it?
Physicists may use Mathematica for calculations, using notebooks as scratch pads or programming sheets. But then they copy out the results and insert them into a LaTex file to eventually produce PDF files, which they load up to the physics archives....
Just for fun I thought I would show how one would do the Sandu Ursu example in Presentations. I have to admit this did take me awhile because I don't do much downloading of curated data nor do I make many data plots. Presentations works with graphics...
I think you made some good points Rodrigo. Here is my attempt at a routine along that line. InstallMathematicaApplication::usage = "InstallMathematicaApplication[\"URL\"] will download and install \ the application zip file...
Yes, that's how many seconds would pass on the clock that near the event horizon compared to 1 second passing on the far clock. And even less time would pass as you got closer. At r = 2 no time would pass. But to make a good book you should get the...
This one is an easy trap to fall into! The problem is that's it's difficult to get Symbol to not evaluate its argument. But you can Clear symbols either by Symbols or by symbol names. And Clear has the Attribute HoldAll. So try this: ...

I agree with Nasser on not having all services pulled into the cloud (small 'c' - it's not God.) This is what I would like to see as a product. A free player that anyone could install on their computer. Any owner of Mathematica, or someone...
Player Pro only kills it.
Mikel, If you will read my tutorial you will see how to name your packages and have access to them. I don't feel like reproducing all of it right here. But also you will have to include the second argument in the BeginPackage statement that declares...
