Studying natural sciences, it is often necessary to resort to mathematical calculations. There are times when you are not quite sure of your answer and want to check whether you are wrong or not, or, more likely, you are too lazy to solve this task and you wish someone would do it instead of you. In cases like that Wolfram Mathematica is a lifesaver. Wolfram Mathematica basically is a very smart calculator that can not only solve a mathematical problems but also draw graphics and edit pictures.
Firstly, Mathematica’s interface may come as a surprise at first. Entering the program in front of you appears literally a blank sheet that is called notebook. The notebook consists of cells which in turn consist of input and output. The interesting part is how you comment in Mathematica. You cannot use “#” to comment on something in your code, as in Python, instead you have to change Wolfram Language that is set as a default to a plain text. …
