Mathematics uses many concepts in threes. The first structure mathematically is a triangle. There are acute, right, and obtuse angles. Trigonometry is the study of the relationship of the sides of a triangle. Have your heard of Pascal's Triangle?

In 1954, the tenth general conference on weights and measures adopted the Kelvin K as the basic unit for measuring all international weights and measures. While the kelvin is the standard unit, degrees Farenheit and degrees Celsius are still in common use in the United States.

The function C(F)=5/9(F-32) relates Celsius temperatures and Farenheit Temperatures. The function K(C)= C + 273.15 relates celsius temperatures and kelvin temperatures.

Let’s convert Fahrenheit to Kelvin. The composition of the function K with the function C is

K(C(F)) = C(F) + 273 = (5/9)(F-32) + 273

Since C converts Fahrenheit to Celsius and K converts Celsius to Kelvin, the composition will convert Fahrenheit to Kelvin.

The Rule of Three is a Mathematical Rule that allows you to solve problems based on proportions. By having three numbers: a, b, c, such that, ( a / b = c / x), (i.e., a: b :: c: x ) you can calculate the unknown number. The Rule of Three Calculator uses the Rule of Three method to calculate the unknown value immediately based on the proportion between two numbers and the third number.

The working of the Rule of Three Calculator can be expressed as follows:

Here is a brainteaser involving 12 toothpicks that’s melting the grey matter of the entire internet. Can you beat it? The challenge is to turn this four-square pattern into just three squares. The rules? You can only move one toothpick at a time in any manner wish, but you cannot break or modify the toothpicks.

Euler’s Formula says: for any convex polyhedron (which includes the five Platonic Solids) the Number of Faces plus the Number of Vertices (corner points) minus the Number of Edges always equals 2
It is written: F + V – E = 2

The Indian numerals discussed in our article Indian numerals form the basis of the European number systems which are now widely used. However they were not transmitted directly from India to Europe but rather came first to the Arabic/Islamic peoples and from them to Europe.

“Energy is not lost or destroyed, it is merely transferred from one party to the next.” – Sir Isaac Newton

In a discussion of energy the basic understanding revolves around the fact that there are three laws. These are simple laws dealing with energy and can be defined as follows:

First Law

Energy can neither be created nor destroyed. This means that you can’t make energy out of nothing— the total amount of energy in the universe is a constant. (Please note that this applies to a closed system – the Earth is not a closed system, the Earth receives energy all the time from the Sun).

Pythagorean teaching – From this comes the great occult axiom: “The center is the father of the directions, the dimensions, and the distances.”

This cube represents six points with man in the middle.

Seven Planetary Spheres

Ancient Greeks taught that souls come to the earth from, and return to the Milky Way via seven planetary spheres – those being Saturn, Jupiter, Mars the Sun, Venus, Mercury and the Moon. In the image above we see the stars and signs of the zodiac at the top, Saturn through Mercury down the back of the chair, the Moon in the sky and Earth in his hands.

The logic of this order doesn’t appear to make sense until you look at an image which shows the spheres mapped onto the seven points (including the center) of a hexagram. Note how the sun (symbolized by a point in a circle) is at the center of this diagram and how the planets are divided with the outer ones being ‘above’ the sun.
