Both scientists and educators at the Center for Astrophysics develop computer simulations to make complex or abstract scientific ideas clearer and more accessible. There are also many activities here to help you explore physics, astronomy and mathematics in new (and fun!) ways. Movies of the X-Ray Universe The Chandra X-Ray observatory has created a series of animations about the X-Ray Universe and how X-Ray telescopes work. Learn More... Warping Space and Time This interactive animation lets you visualize how space and time are distorted around a massive object like a black hole. Learn More... Black Hole in Motion Here weİve gathered the best visualizations of black holes from the CfA as well as from NASA and other major research centers. Learn More... Make your own spectrum MiniSpectroscopy is a virtual spectrocope that allows you to create a spectrum and see its graphical (intensity vs. wavelength) representation. Learn More... Waves on a String Play around with waves on a string, and explore concepts of superposition, standing waves and boundary conditions. Learn More... Kinematics MouseLab, allows you to graph relationships between several fundamental physical concepts: displacement, velocity, and acceleration. Learn More... Energy Paths Learn about sources of energy and the conversion of energy from one type to another. Learn More... Cat-Traption Build a crazy cat feeder and learn about energy conversion! Learn More... Compressibility of Air Why can air be compressed and water cannot? Carry out a virtual experiment! Learn More... The Towers Problem A mathematical puzzle of combinations and permutations.
