Description: Illustration of a wave equation

Description: Illustration with euler's equation

Description: Unsolvable 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: 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: Energy is equal mile coffee square

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: Entropy Equation with illustration.

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: 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: Dance Math features with this design! The funny gift for nerds and mathematicians.

Description: Stephen Hawking Equation

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: A minimalist black background with large white lettering displaying the mathematical equation "y = mx + b". The text is centrally aligned and takes up most of the visible space.

Description: illustration of the Einstein Equation

Description: Navier Stokes Equation Fluid Dynamics Math Design

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: Mass-energy equivalence.

Description: Engineer Physics Relativity Equation Einstein You Matter

Description: A minimalist white text equation on a black background. The equation reads 'ih dΨ(r, t)/dt = [-ħ²/2m ∇² + V(r, t)] Ψ(r, t)'. The text represents a fundamental equation in quantum mechanics.

Description: Quantum mechanics Schroedinger equation

Description: A mathematical expression featuring a large summation symbol on the left, followed by an equals sign. To the right, the text '$x_n \times exomt$' is displayed. Below the summation symbol are the words 'limt' and 'limt dimt', indicating a limit.

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