The Collatz conjecture is one of the most interesting and still unsolved problems in mathematics. It is named after the German mathematician Lothar Collatz (1910 – 1990), who invented it. It sounds very simple, and it is hard to believe that no one has managed to prove it so far: Pick a random integer >Continue reading “Checking the Collatz conjecture (with Calcpad)”

How units work?
In this post, we will take a quick look inside Calcpad and see how units actually work. But first, let’s make a brief overview of the theoretical basis. Theoretical basis There are only seven base units in the whole universe. They correspond to the seven physical dimensions: mass – kilogram (kg) length – meter (m)Continue reading “How units work?”
Quadratic equation – part II
In the previous post we created a simple program to solve a quadratic equation. We used the well known method from school: In this post we will make our program more professional and add some advanced features. Currently, it is fine for personal use, but if we want to give it to other users, weContinue reading “Quadratic equation – part II”
My first program – quadratic equation
Lets write our first program with Calcpad. Most programming languages usually start with “Hello world!”, but for Calcpad, there is nothing much to do, except to write the text in quotes: “Hello world from Calcpad!” Then press Enter and the text will appear in the output. So, let’s do something more useful and solve aContinue reading “My first program – quadratic equation”
