Description: Illustration with euler's equation

Description: Unsolvable equation

Description: Illustration of a wave equation

Description: The Lagrangian that describes almost everything in the universe, and the closest we have got to a theory of everything.

Description: The beautiful equation, or the Euler equation of complex analysis, this bit of mathematics enjoys accolades across geeky disciplines. Swiss mathematician Leonhard Euler first wrote the equality, which links together geometry, algebra, and five of the most essential symbols in math -- 0, 1, i, pi and e -- that are essential tools in scientific work. Theoretical physicist Richard Feynman was a huge fan and called it a "jewel" and a “remarkable” formula. Fans today refer to it as “the most beautiful equation."

Description: Schrodinger equation, one of the most famous equations among physics majors, and one of the most influential ones since it opens doors to theories we didn't know existed.

Description: Energy is equal mile coffee square

Description: It's all fun and games until someone loses an eye--or an i, the imaginary number missing from this equation gone wrong. The perfect gift for math teachers, or for anyone who enjoys a geeky pun.

Description: Show your love for your favorite classic Japanese TV show with this unique design!

Description: Equations that describe the natural world can convey profound truths while at the same time, to a trained eye, look absolutely beautiful. It is like learning to appreciate a work of art. Art may or may not be eternal. These poetic truths are. The equations show here are 1.Boltzmann equation 2. Euler Lagrange Equation 3. Dirac Equation 4. Euler Identity 5. Navier Stokes equation.

Description: Another cow has been pressed into service for a mathematical joke, but this time in the graphs of sine and co(w)sine equations. The perfect gift for the math teacher or pun enthusiast.

Description: Entropy Equation with illustration.

Description: Being normal is overrated. That's why this t-shirt features graphs of other great distributions: hypergeometric, negative binomial, poisson, and geometric.

Description: Cute aliens display the quadratic formula like you've never seen it before. It's a great gift for math teachers, adorably geeky sci-fi enthusiasts, and more.

Description: Excuse Me While I Science: Think Like A Proton and Stay Positive

Description: These kawaii cute 3D shapes are speaking volumes - each has a speech bubble with the equation for calculating their volume!

Description: Illustration with euler's equation

Description: Also know as Euler's identity. It combines the numbers 0, 1, pi, e, and i in one equation.

Description: Funny dinosaur physics equation. Science Geek

Description: The infamous and very useful equation to move from contour integral to surface integral, also known as Stokes theorem.

Description: Challenge the limits of logic and math with this thought-provoking design featuring the famous paradox: 1 + 2 + 3 + 4 + … = -1/12. While it may seem impossible, this surprising result pops up in advanced mathematics and quantum physics. Perfect for math lovers, physics geeks, or anyone who enjoys mind-bending concepts. Wear it as a conversation starter and show off your appreciation for the weird and wonderful world of infinite sums!

Description: illustration of the Einstein Equation

Description: Navier Stokes Equation Fluid Dynamics Math Design

Description: In particle physics, the Dirac equation is a relativistic wave equation derived by British physicist Paul Dirac in 1928. He developed an equation that explained spin number as a consequence of the union of quantum mechanics and special relativity. The equation also predicted the existence of anti-matter, previously unsuspected and unobserved, and which was experimentally discovered in 1932.

Description: The Religion Equation. Cult + Time = Religion. What's the difference between a cult and religion? Time! A cheeky, humorous concept designed for atheists and agnostics and maybe religious people with a sense of humour.

Description: For the math nerds, the pun lovers, and everyone aiming higher—this clever equation design says it all: “Be Greater Than Average.” A subtle and geeky way to flex your brainpower while inspiring others to rise above mediocrity. Perfect for teachers, students, mathletes, and logic lovers alike!

Description: Comic Equation

Description: Engineer Physics Relativity Equation Einstein You Matter

Description: Quantum mechanics Schroedinger equation

Description: In the general theory of relativity, the Einstein field equations relate the geometry of spacetime to the distribution of matter within it.

Description: The Dalek Equation . . . For the Whovians who love a bit of science with their sci-fi, 'The Dalek Equation' is the perfect addition to the wardrobe. Whether you're traveling through time or just heading to the shop, this is the ultimate way to represent the Doctor's greatest foes.

Description: If Heisenberg were being dramatic his theory may have sounded more like this.

Description: Get ready for a delightful twist in the world of physics: Einstein's field equation! Because nothing says "we're related" quite like this fascinating formula.

Description: Illustrated electricGauss law from Maxwell equations.

Description: This clever math pun design features a yellow parabola graph with the equation y = ax² + bx + c and the phrase “Working on My Quads.” Perfect for math lovers, algebra fans, teachers, and students, it blends academic wit with nerdy humor. A fun choice for anyone who appreciates equations and clever wordplay.
