How to calculate square/cubic root by hand?

Today, technologies make everything easy and fast. And sometimes, when we see the ancient marvels of engineering, we wonder: “How they designed this without computers”? And the answer is: “with knowledge, inspiration and hard work”. However, being almost irreplaceable, computers makes us more and more adjective. Our brains become lazy and we are losing someContinue reading “How to calculate square/cubic root by hand?”

What’s new in Calcpad, version 5.6.3?

Since version 5.6 was released, we made some little, but nice and useful improvements. They were driven mostly by our small and dedicated GitHub community. Some of the most important changes are listed below: 1. Autorun mode When enabled, the results are refreshed automatically each time you edit the code and leave the current line.Continue reading “What’s new in Calcpad, version 5.6.3?”

How to plot the Julia Set

In the previous post we discussed the Mandelbrot set. There is another beautiful algebraic fractal, called Julia set 𝓙. It is named after the French mathematician Gaston Julia, who has discovered. It is obtained by the same formula as the Mandelbrot Set: zn+1 = zn2 + c The difference is that z0 = x +Continue reading “How to plot the Julia Set”

Math Art with Calcpad

Most people consider math boring, but sometimes it can be really beautiful. Recently I found some unusual application of Calcpad – to draw nice pictures using math formulas. In general, you can plot functions of two variables using the $Map command: $Map{f(x;y) @ x = a : b & y = c : d} IContinue reading “Math Art 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?”

Calculating with units

Unit conversion is one of the most tedious jobs when doing calculations. Although not very difficult, it is repetitive and time consuming. For example, lets calculate the stress in a steel beam. Assume that span length is in meters, section dimensions are in mm, geometrical properties are in cm2 (cm3, cm4), section forces are inContinue reading “Calculating with units”
