Pi day

Celebrating PI Day

Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.
Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.

Paris is well worth a mass.

When his cousin Enrique III, the last of the Valois dynasty, named him his successor, Enrique IV already knew that the path to the throne was paved with thorns.

The religious wars had divided not only France, but all of Europe, and although he had been baptized catholic, he was educated in the Calvinist doctrine, and suffered in his own flesh. He already remembered how, after spending four years reigning over France, he had to renounce his faith and embrace the catholic doctrine again so that Saint Liga of Paris would accept him as king.

The disputes of power against the catholic Felipe II continued years later and, while he read the letter that his secretary had brought him, Enrique IV was astonished by the talent of Francois Viete to interpret the ciphered messages that the Spanish used to communicate within themselves.

He closed his eyes and tried to remember some notion of algebra that Viete had taught him. He remembered that he used the consonants, B, C, D…, to supplement the known quantities, and the vowels, A, E, I…, the unknown.

When green is red

The 26-year-old young man, John Dalton, was comforted by his older brother, Jonathan, while they took a walk through the English city of Kendal.

-John, don’t take it so seriously. I’m sure that mom didn’t want to offend you.

John didn’t seem very convinced and looked in disbelief at the garment that he had given to his mother, and that she returned it made him visibly upset.

-I don’t understand why she doesn’t like it, the clerk assured me that the cloth was of the highest quality.

-You know that mom is very religious and the color red… -answered his brother Jonathan.

-You didn’t realize it either -John objected and, while he threw the scarlet garment in the river, he began to think: Why couldn’t his brother and him distinguish the colors?

Two years later, in 1793, John Dalton published a work where he described a type of disorder the he himself suffered, known from then on as daltonism.

Dalton became famous, and is still known for his atomic theory, that plays a fundamental role in numeric proportionality.

For example, a water molecule has two hydrogen atoms and one oxygen atom. His theory affirms that, regardless of the amount of water, the quantity of hydrogen and oxygen atoms always has the same proportion (ratio).

The love of the Moon

Christopher Columbus’ ship was shipwrecked for a short time in the island of Jamaica. His men threatened mutiny, and to compromise the situation, the indigenous, tired of exchanging little mirrors and accounts, refused to supply them with food.

The situation was hopeless and Columbus, to calm down his men, promised them food and a meeting with the chief of the indigenous people that same night.

-You know that you have all angered me with your poor cooperation, I will make the moon turn red with blood and then it will dissapear!

The indigenous chiefs looked at the moon to make sure the threats of Columbus were real, terrified, they asked him to resurrect the moon, promising to continue bringing food to him and his crew.

Columbus moved his arms, as if he were calling someone, and assured them:

-The moon will appear new this same night, but if you take back your word again, it will return to how it was.

After that, he returned to his quarters satisfied, congratulating the men for bringing the Ephemerides of the famous mathematician Regiomontanus, who predicted the eclipse that just happened.

Regiomantanus also wrote about angles, and measuring in degrees, minutes, and seconds.
