Hello fellow Steemians, and budding scientists!!
Have you ever thought how simple the world would be if a program could plot complex curves in a jiffy!! ...and solve all your math problems in seconds?
It will definitely help us in understanding things better if not copying ready-made answers!
Well, welcome to the world of Wolfram Mathematica!!

The thing that got me started on the science that I've been building now for about 20 years or so was the question of okay, if mathematical equations can't make progress in understanding complex phenomena in the natural world, how might we make progress?
---Stephen Wolfram---
INTRODUCTION
In the words of Wikipedia :
Wolfram Mathematica is a program which is basically a modern technical computing system spanning most areas of technical computing — including neural networks, machine learning, image processing, geometry, data science, visualizations,
and others. The system is used in many technical, scientific,
engineering, mathematical, and computing fields. It was conceived by Stephen Wolfram and is developed by Wolfram Research of Champaign, Illinois. The Wolfram Language is the programming language used in Mathematica.
- History : Wolfram Mathematica built on the ideas in Cole and Wolfram's earlier Symbolic Manipulation Program (SMP). The name of the program "Mathematica" was suggested to Stephen Wolfram by Apple co-founder Steve Jobs although Wolfram had thought about it earlier and rejected it.
- Uses (https://www.wolfram.com/language/) :
The Wolfram Language allows programmers to operate at a significantly higher level than ever before, by leveraging built-in computational intelligence that relies on a vast depth of algorithms and real-world knowledge carefully integrated over three decades. Scaleable for programs from tiny to huge, with immediate deployment locally and in the cloud, the Wolfram Language builds on clear principles—and an elegant unified symbolic structure—to create what is emerging as the world's most productive programming language and the first true computational communication language for humans and AIs.
Step-1) Accessing the Software
The software is available as a desktop stand-alone, but can be quite costly.
Here are some of the things you can try :
- Buy the original complete version of the software :
- Try a 15-day free trial b registering here : https://www.wolfram.com/mathematica/trial/
- Create an account and use the free web version which has all the critical features. Here : https://www.wolfram.com/programming-lab/
- Start directly online (work will not be saved) : https://lab.open.wolframcloud.com/app/
Step-2) Getting Started
- Run Wolfram Mathematica, open a new notebook by using the shortcut keys Ctrl + N.
- In the front-end kernel that appears enter "2+2" (without the quotes) and press Shift + Enter to run the cell (contains the input : 2+2) you just created.
- Trying simple calculations like `2+2, 2*2, 3*(4+3)/2` :
 `Plot3D[{curve-1,curve-2,...},{var-1,min_var-1,max_var-1},{var-2,min_var-2,max_var-2}]`
- Let's plot `Sin[x]*Cos[x]` in the range x=[-Pi,Pi], y=[-Pi,Pi]

Model the egg-crate using Mathematica, and print it using your 3-D printer...!!
Step-3) Plot Function
Step-4) Making 3-D plots!! : Plot3D Function
Isn't that a very beautiful curve!!
Now, one may ask what's the use of learning all this!!
Let us list two uses....
That's all for the Introduction, more to come...in the next posts we will learn to do more with Mathematica, and the complexity of the codes will also increase significantly... <br>Don't worry.
Keep practicing and tinkering!
