E and M and Everything Else

The electromagnetic spectrum is the range of electromagnetic radiation frequencies in the universe, which includes radio waves, x-rays, all kinds of light, gamma rays, etc. The reason the Em spectrum is segregated as such is because of its common interaction with matter. For example: gamma rays tend to create particle, anti-particle pairs when interacting with other matter, infrared rays tend to vibrate molecules in matter. This radiation is known to occur any time charged particles are accelera

Call of Physics

I'm sure everyone reading this knows what a sniper rifle is. You know: long barrel, cylindrical scope, big long bullets, used for long range and heavily armored targets. But, what you might not know is how powerful one is. The standard NATO sniper rifle bullet is the .5 BMG. Made in 1921, the most powerful version of that cartridge is about .052 kg, and leaves the rifle at 882 m/s. p = mv, so p = (.052)(882) = 45.86 Ns. That big fat hunk of copper has about 50 Ns of life in it. Now, the average

Big, Empty Space

Something that baffles scientists today is a strange situation called the Fermi Paradox, named after Italian physicist Enrico Fermi. The basic conundrum is that there's an incredibly high probability that alien life forms not only exist in the universe, but nearby Earth. The reason for this statement is the radically large number of solar systems in our galaxy alone. With so many stars in the observable universe, billions are similar to our Sun. The likelihood that many of these stars have

AP Spheres

In my last blog I talked about the three (up to five) types of civilization as labelled by the Kardashev Scale. I also said that type II civilizations can harness the full power of their star, with something called a Dyson Sphere. The Dyson Sphere is a theorized invention by Olaf Stapledon. The basic goal of the project is to someday completely harness the Sun’s energy output. This includes every single Joule of especially heat and light energy the fusion within the Sun’s core creates.

A Tele-Vision for the Future

TV's have risen in popularity tremendously since their invention, and despite continuing advancements in communication they continue to be a major project across the world. This relevance is in a large part due to the innovation which has kept them higher quality, easier to operate, and/or more useful than ever. TV's started out using cathode ray tube technology to display a picture. In this setup, a vacuum tube rockets electrons towards a phosphorescent screen. Anodes accelerate the electr
