Mathematicians
Often, to completely understand the importance of a mathematical theory, it's essential to know about the person who developed it. This category is where all questions about historically significant mathematicians should be asked.

Why was Archimedes running down the road yelling Eureka?
It was because he seemed really excited by his discovery, that is when you put an object into water, some of the water gets displaced or pushed out of the way.
Why is Pythagoras' theorem useful?
well...
one of its uses can be as follows:
you see trigonometry deals with right angles right, so through the Pythagoras theorem you can find out the sides of the triangle, without which trig would be impossible!
Pythagoras discovered the ratio for creating the interval of a perfect octave was?
He discovered the ratio of a perfect octave is 2:1.
What are euclid's achievements?
Euclid is best known for his treatise on mathematics, The Elements. His book is one of the most influential works in the history of mathematics, serving as the main textbook for teaching math, especially geometry, from the time of its publication until the late 19th or early 20th century. The Elements is a mathematical and geometric treatise consisting of 13 books written in Alexandria at around 300 BC. It is divided into thirteen books which cover plane geometry, arithmetic and number theory, irrational numbers, and solid geometry, such as definitions, propositions, theorems, constructions, the five postulates (axioms), and mathematical proofs of the propositions. Axioms are statements that are accepted as true.
Ok so basically the chebyshev's theorem states that 75% of your data will lie within 2 standard deviations of the mean and that 89% of your data will lie within 3 standard deviations of the mean. And I believe that this theorem is much more precise than the Empirical Rule, which assumes normality and can be off.
I am currently taking a stats. class if I didn't help or my wording is unclear please let me know. Also any information here was obtained or learned from the book called Elementary Statistics by Mario F. Triola

Perfect octave.
What did Euclid's book Elements contain?
The book Elements contained axiomic proofs for plane geometry.
Where was Diophantus educated?
He lived in Alexandria, which in his time was a Greek city but is now in Egypt.
Some rules for members of Pythagoras' Philosophical and Religious School?
Pythagoras wouldn't eat beans because he thought they contained/were human souls, and would not wear cloaths made of animal skins.

Augusta Ada King-Noel, Countess of Lovelace, was the only child of Lord Byron. She did have several illegitimate half brothers and sisters.
How did Archimedes die and when?
When the Romans attacked Syracuse, the troops were told to take Archimedes alive. As they invaded the city, troops were sent out to raid and find the scientist. As legend has it, when Archimedes was found, he was involved in some task and refused to be interrupted. When the soldier who found him became impatient, he killed Archimedes
