Description: In 1822, Joseph Fourier showed that some functions could be written as an infinite sum of harmonics. This method called fourier series allowed us to construct very complex signal by only using the summation of sine and cosine signal. Furthermore by taking some statistic method, the scientist figure out that this complex signal can be transformed into frequency domain, so the analyzing or utilization of signal was becoming more advance. Nowadays application of fourier transform can be found everywhere. Your smartphone, your face recognition, radio, stock exchange, heart monitor, etc. And finally it is time to found its application in your daily outfit. Grab it fast.
Description: A design featuring mathematical symbols at the top: the square root of -1, 2 raised to the power of 3, sigma, and pi. Below these symbols, in a different font, is the text "...and it was delicious!". The entire composition is in a dark blue color against a black background.

Description: A scientific diagram displaying fluid dynamics concepts. It features an airfoil cross-section with flow lines, a complex partial differential equation, three visualizations of flow around a cylinder at different Reynolds numbers, and three corresponding plots showing pressure (P/P) and velocity (V/P) against spatial variables (Yp, YB, XB). The overall style is monochrome with white lines and text on a black background.
Description: A text-based composition with mathematical formulas and phrases. The top reads "I'LL DO" and "I'LL EVEN DO". Below are the equations $a^2+b^2=c^2$ and $A=\pi r^2$. The word "BUT" is centered, followed by the equation $y=mx+b$. The bottom text states "THAT'S WHERE I DRAW THE LINE!". The formulas are depicted with simple line drawings.
