Hi Ravi-Praveenkumar Padnaram,
thank you very much for your kind words. I am glad if what I wrote helped.
I am not working for Wolfram, but I do really like the technology that they produce. I work at a University and I teach using Mathematica. I see that you are interested in Astronomy and Supersymmetry. I guess that the features of the recent versions of Mathematica must be very useful then. Also, a basic account of the Wolfram Programming Cloud is indeed free.
Given that you are interested in Astronomy (I assume from a rather theoretical perspective) you might like this:
Telescope control with Mathematica
All that stuff is basically free if you have a RaspberryPi. I got students to do really cool projects with Mathematica on a Raspberry.
Best wishes and thank you,
Marco
