Hard Sci Fi Socks
Description: Black Hole T-shirt for Universe lovers. A black hole is a region of spacetime where gravity is so strong that nothing – no particles or even electromagnetic radiation such as light – can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. Perfect gift for Christmas and Birthday!
Description: Three astronomers who changed our understanding of the stars. Henrietta Swan Leavitt developed a system for measuring distances in the cosmos by tracking the luminosity of stars. Annie Jump Cannon classified hundreds of thousands of stars, and her system is still in use today. Cecilia Payne found the temperature scale of stars by understanding the abundances of hydrogen and helium in them, and her 'Stellar Atmospheres' is widely acknowledged as the most brilliant Ph.D. thesis ever written in astronomy.
Description: This pattern shows the trajectories of a system of mathematical nonlinear equations. The effect is known as Butterfly effect and chaos theory. With a glance to the 1970s, and a bit psychedelic, this is a really cool design for school, college and university teachers students, geeks, nerds, science lovers and professional daydreamers. Original design by blacklinesw9 for clothing, home decor and accessories
