One of the single most important numbers in history, its applications include its uses in world-wide statistics, predicting weather patterns, and in other applications that require massive computational power. The most recognized mathematical constant in the world, it is interesting to note that the π (piwas) is the 16th letter in both the Greek and English alphabet.
Euler’s Number (2.718…)
Like pi, the Euler is an irrational, non-repeating and non-terminating number, which denotes the natural limit for many processes and applications in nature, science and mathematics, especially in economics. Named after Leonhard Euler, it was actually discovered by his student Bernouli who went to a loan shark to borrow money. Then, while deciding on the rate of compound of interest that would be applied he came up with the approximate number that we now know as e, which functioned as a limiting factor.
Euler’s Constant (.57721…)
Not to be confused with Euler’s number, the Euler’s constant, which is sometimes called the Euler-Mascheroni constant, has significant application especially in number theory and other engineering-related formulas and calculations.
A mathematical constant used to (are you ready for this?) describe the dynamic systems of successive differences with period-doubling using the bifurcation diagram before they enter the chaotic regime. What a mouthful! Discovered by Mitchell Feigenbaum in 1975 using a standard issue calculator, he also proved that the mathematical constant 4.6692 was present in a number of mathematical functions related to chaos.

Also known as zilch or nada, zero is known for being the number that enabled the denominational number system and became the basis for modern mathematics. Also known as a ‘neutral’ element, it can be added to any number but will not change the value of the sum; and is known to be an ‘absorbing’ element in multiplication as everything that you multiply to it will still result in zero.

The luckiest number, seven, has been known for the days of the week, the deadly sins, continents, colors of the rainbow, musical notes, 7-year itch, 7th heaven and so much more. In Europe, people believed that the 7th son/daughter of the 7th son/daughter will have magical powers; while Latin Americans believed that they will become werewolves or lobison. It is also a part of the ‘blue-seven’ phenomenon where the frequent choice of people when asked to name their favorite number is 7, while their favorite color is blue.
The Golden Ratio
Also known as the Golden Mean or the Golden Section, this is an expression that describes universally perfect proportions in sciences such as architecture and anatomy. Approximately 1.6180339887, two quantities are considered to be in perfect golden ratio if the ratio of those two quantities and the larger one is the same as the ratio between the larger and smaller ones.
According to Pythagoras, the number 5 was the perfect number of human microcosm. Aristotle also added a 5th element to the 4 elements of ancient Greek studies and called it Ether, which has become the basis for most of the spiritual practices of the ancient alchemists. It also has some spiritual significance and symbolism in other cultures, including the Chinese and Japanese Buddhists. This number has also become the basis of discordianism, a jocular pseudo religion popularized by Robert Anton Wilson, which believed that everything that happens in the universe has a connection to 5 or a multiple of five.
The number of perfection, it has been associated with infinity and the ancient Egyptians believed that it is the number of balance and of the cosmic order. For the Japanese it means multiplicity while the Pythagoreans believed that it is a symbol of love and friendship, so they called it the Great ‘Tetrachtys.’
