If you look closely at the Google Doodle for today, you can see the faint outline of the company’s name, appearing as recently erased markings on a chalkboard. What takes center stage is the mathematical equation xn + yn ≠ zn (when n > 2)
If you mouse over the doodle, this message will pop up: “I have discovered a truly marvelous proof of this theorem, which this doodle is too small to contain.”
Google DoodlesWe have discovered a truly marvelous proof of this theorem, which today’s tweet is too small to contain. #Fermat http://t.
Fermat, a French lawyer and amateur mathematician, proposed the xn + yn ≠ zn theory as an extension of the concept of Pythagorean triples.
We all learned in basic algebra about using the Pythagorean Theorem to find the side lengths in right triangles – a2 + b2 = c2. where “c” is the hypotenuse.
Pythagorean triples are sets of positive integers a, b, and that fit the a2 + b2 = c2 equation. For instance – 3, 4, and 5 is a set:
That’s where Fermat’s Last Theorem take off. His xn + yn ≠ zn (when n > 2) states that there are no sets of integers for x, y, and z that satisfy the equation when n is greater than 2. Basically, the equation will never work for any set of integers when they are taken to any higher power than 2 (squared).
Fermat simply stated this theorem and left it to other mathematicians to prove, and they tried – for 358 years. No mathematician could write a proof of Fermat’s equation until 1995 when British mathematician Andrew Wiles offered the first complete proof as part of the modularity theorem for semistable elliptic curves.
