"A Slower Speed of Light is a first-person game prototype in which players navigate a 3D space while picking up orbs that reduce the speed of light in increments. Custom-built, open-source relativistic graphics code allows the speed of light in the game to approach the player's own maximum walking speed. Visual effects of special relativity gradually become apparent to the player, increasing the challenge of gameplay. These effects, rendered in realtime to vertex accuracy, include the Doppler effect (red- and blue-shifting of visible light, and the shifting of infrared and ultraviolet light into the visible spectrum); the searchlight effect (increased brightness in the direction of travel); time dilation (differences in the perceived passage of time from the player and the outside world); Lorentz transformation (warping of space at near-light speeds); and the runtime effect (the ability to see objects as they were in the past, due to the travel time of light). Players can choose to share their mastery and experience of the game through Twitter. A Slower Speed of Light combines accessible gameplay and a fantasy setting with theoretical and computational physics research to deliver an engaging and pedagogically rich experience."

"The activity will help give students a kinesthetic feel for the inertia concept. This lab is a great way to provide students with an experience that can be very thoroughly discussed and analyzed."

Physics experiments/activities do not have to be costly in time or resources.  Teachers also do not need to limit their equipment purchases to "high tech" or specialty materials sold exclusively through science supply catalogs.  Many valuable data collection activities can be performed using inexpensive materials that may be purchased from local department, hardware, and/or toy stores. 

Tutorials in Physics Sense-Making: Tutorials work on building concepts and developing physical intuition that relates their everyday experience.

Einstein was right, neutrinos can't travel faster than the speed of light. Read what happened in this post.
