Genius (mathematics software)

Genius (mathematics software) is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Genius (mathematics software) rather than just read about it. In short: Genius (also known as the Genius Math Tool) is a free open-source numerical computing environment and programming language, similar in some aspects to MATLAB, GNU Octave, Mathematica and Maple. Genius is aimed at mathematical experimentation rather than computationally intensive tasks.

Key takeaways

Genius (mathematics software) belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Genius (mathematics software) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Genius (mathematics software) from memory before moving on to harder problems.

Reference excerpt

Genius (also known as the Genius Math Tool) is a free open-source numerical computing environment and programming language, similar in some aspects to MATLAB, GNU Octave, Mathematica and Maple. Genius is aimed at mathematical experimentation rather than computationally intensive tasks. It is also very useful as just a calculator. The programming language is called GEL and aims to have a mathematically friendly syntax. The software comes with a command-line interface and a GUI, which uses the GTK+ libraries. The graphical version supports both 2D and 3D plotting. The graphical version includes a set of tutorials originally aimed at in class demonstrations.

History Genius was the original calculator for the GNOME project started in 1997, but was split into a separate project soon after the 0.13 release of GNOME in 1998. Because of this ancestry, it was also known as Genius Calculator or GNOME Genius. There was an attempt to merge Genius and the Dr. Geo interactive geometry software, but this merge never materialized. Version 1.0 was released in 2007 almost 10 years after the initial release.

Example GEL source code Here is a sample definition of a function calculating the factorial recursively

function f(x) = ( if x <= 1 then 1 else (f(x-1)*x) )

GEL contains primitives for writing the product iteratively and hence we can get the following iterative version

function f(x) = prod k=1 to x do k

Worked examples

Example 1 — a first encounter with Genius (mathematics software)

Start with the simplest possible case. Write down what Genius (mathematics software) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Genius (mathematics software) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Genius (mathematics software) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Genius (mathematics software)

In research: Genius (mathematics software) appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Genius (mathematics software) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Genius (mathematics software) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Array programming languages, Free educational software, Free mathematics software, so understanding it makes those chapters shorter.
In everyday life: Look for Genius (mathematics software) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
