The greatest ideas in mathematical history โ from ancient Greece to the 20th century. Click any theorem to expand it!
Proven by the ancient Greek mathematician Pythagoras (~500 BC), this theorem states that in any right triangle, the square of the longest side (hypotenuse, c) equals the sum of the squares of the other two sides.
It's used in architecture, navigation, engineering, physics, and computer graphics every single day. If your screen shows a diagonal line โ Pythagoras made it work!
Discovered by Leonhard Euler in the 18th century, this equation is called "the most beautiful in mathematics" because it connects five of the most fundamental constants in all of math in a single elegant statement:
e (โ2.718) ยท the base of natural logarithms ยท i ยท the imaginary unit (โโ1) ยท ฯ (โ3.14159) ยท the ratio of a circle's circumference ยท 1 ยท the unit of counting ยท 0 ยท the concept of nothing
Each number in the Fibonacci sequence is the sum of the two before it (0+1=1, 1+1=2, 1+2=3, 2+3=5โฆ). Introduced to Europe by Leonardo Fibonacci in 1202, this sequence appears everywhere in nature.
Divide any Fibonacci number by the one before it and you get approximately 1.618 โ the Golden Ratio (ฯ). This proportion is found in the Parthenon, the Mona Lisa, spiral galaxies, hurricanes, and the human face.
Every whole number greater than 1 can be written as a unique product of prime numbers, in exactly one way. For example: 60 = 2 ร 2 ร 3 ร 5. No matter how you break down 60, you always arrive at these same primes.
Prime numbers (2, 3, 5, 7, 11, 13โฆ) are the "atoms" of mathematics โ the indivisible building blocks from which all whole numbers are constructed. This theorem, known since ancient Greece, is why primes matter so profoundly.
In 1637, mathematician Pierre de Fermat wrote in a book margin: "I have a truly marvelous proof of this theorem, which this margin is too narrow to contain." His claim: there are no whole-number solutions to aโฟ + bโฟ = cโฟ when n is greater than 2.
Mathematicians tried for 358 years to prove it. Thousands failed. Finally in 1995, Andrew Wiles published a 130-page proof โ after working in secret for 7 years. When he presented it, the mathematics community wept.
Georg Cantor proved in 1891 that there are different sizes of infinity โ and some infinities are genuinely larger than others. The infinity of all real numbers (including decimals) is strictly bigger than the infinity of all whole numbers.
He showed this with a clever "diagonal argument" โ you can always construct a real number that's missing from any list of real numbers, proving the list can never be complete no matter how long it is.
In 1742, Christian Goldbach wrote to Euler claiming every even number greater than 2 can be written as the sum of two prime numbers. For example: 4=2+2, 6=3+3, 8=3+5, 100=3+97, 1000=3+997.
It has been verified by computers for every even number up to 4 ร 10ยนโธ (that's 4 quintillion!). But no one has ever proven it works for ALL even numbers. It remains one of the oldest unsolved problems in all of mathematics.
