Feeling a Bit Slow?
Look in any physics textbook and the speed of light will be listed: approximately 300,000,000 meters per second. That’s a big number, but what exactly does it mean? Well, to […] Continue reading
Near Speed of Light Travel in the Atmosphere
When physics classes learn about relativity, typical problems involve calculating relative velocities, masses, or distances for objects moving near the speed of light, 3 * 10^8 m/s. These objects might be objects like spaceships, travelling in outer space, but they are often more common objects like cars and trains, or even baseballs. The two different […] Continue reading

While searching for a good astronomy application to blog about, I found a lot of interesting moon apps, but I think the most helpful app for this class would have to be Lunar Phase. It’s a free app available for Android that not only shows you the current phase of the moon and the moon […] Continue reading
