Finding min, max in a sequence and plotting the distances

Let’s say that we have a sequence of numbers in consisting of whole numbers, fractions, positive and negative numbers of varying length, that is, of no predefined length (e.g.2.25, 5.25, 6.75, 8.25, 9.75…). What we want to do is to sort the numbers in ascending order, and find the differences between 2 adjacent numbers and […]

Calculating Euclidean Distance in Python

Euclidean distance is the length of the line segment between two points in Euclidean space. It can be calculated from the Cartesian coordinates of the points using the Pythagorean theorem. It is a simple formula enough to be calculated by hand but powerful enough to be used in Machine Learning and Artificial Intelligence applications for […]

Simulating object’s free fall on different planets, sun, and the moon

How can we simulate a box being dropped straight from some height on Earth and graphically show the action in real-time? How will it be different on the Moon? Or on the Sun (assume it can resist the high temperature), or on other planets including dwarf planet like Pluto? Well, that was my curiousity that […]
