Number Theory T-Shirts

"73 is the 21st prime number. Its mirror, 37, is the 12th and its mirror, 21, is the product of multiplying 7 and 3... and in binary 73 is a palindrome, 1001001, which backwards is 1001001." --Sheldon Cooper, PhD.

"Agreed, what's your point?" "There's no point, I just think it's a good idea for a tee-shirt." Over ten years of scientific hilarity and insanity, show your long-time love for The Big Bang Theory with this commemorative shirt!

A Whole Llama Learning Going On

Double-sided, original design from SpacePod Tees, front featuring prime number 73 and its mirror, prime number 37, featured in reverse on the back – yes, to induce an extra level of deep mathematical thought. A unique gift for those born in 1936 – they turned 37 in 1973, and those born in 1964 – who will turn 73 in 2037! Not just for the modern math nerd, but for the rest of us who leave the number crunching to our trusty accountants

Lagrange made significant contributions to the fields of analysis, number theory, and both classical and celestial mechanics.

No way

Euler's theorema maths perfect gift for math teacher,physics,engineers,and everybody that loves mathematics

Prime number 73 in all its retro ink-rolled glory! Not just for the modern math nerd, but for the rest of us who leave the number crunching to our trusty accountants. A great gift for those turning 73 and dig celebrating their arrival at the 21st prime number. And for those born in 1973 who can proudly holler, I’m here, and born in the year of the 298th prime number! Take that, world!!

This "Fermat's Last Theorem" (a.k.a. "Fermat's Conjecture") design in Japanese showcases the beauty of mathematics and the elegance of the Japanese language. Fermat's Last Theorem, named after famous mathematician Pierre de Fermat (1607–1665), states that the sum of the n-th powers of two positive integers x and y does not equal the n-th power of a positive integer z for any integer value of n greater than 2. This product is perfect for number theory enthusiasts and Japanese language learners alike.

Fibonacci, an Italian mathematician of the Middle Ages, introduced the Fibonacci sequence, a numerical pattern where each number is the sum of the two preceding ones. His work greatly influenced mathematics, number theory, and applications in various fields such as finance, nature, and art.
