pwn physics 365: physics history, vocabulary, and resources every day of the year

On this day in physics: On 11 January 1787 William Herschel, discovered the first two moons of Uranus, Titania and Oberon, roughly six years after he discovered the planet itself. The names were given 65 years later by Herschel's son. Word of the Day: Matter is the stuff around you. It is anything that has takes up space and has mass. This definition is designed to exclude energy such as light, or the motion of particles, such as sound. The majority of matter is made up of atoms, which are made of protons, neutrons, and electrons. Protons and neutrons are then of course made up of up and down quarks. There are four states of matter. The state with the lowest energy is a solid. Next is liquid. Next is gas. Finally, the least commonly known state of matter is a plasma. Matter behaves distinctly different in each state. Killer Resource: Wolfram Online Integrator.

On this day in physics: 10 January 1936 Birth of Robert Woodrow Wilson, one of the discoverers of the cosmic microwave background radiation along with Arno Penzias (Dig Deeper at pwnphysics.blogspot.com) Speed is...wait what? Didn't we just do this on Tuesday? The answer is no. On Tuesday we covered velocity, which is drastically different from speed.  Let's explore.Speed describes the rate at which an object is changing position, or moving through space, or any other medium, just like velocity. However, speed solely indicates the rate of change of motion. Nowhere in the speed can you find the direction of this motion. Consider the speedometer in your car. It tells you that you're going 65 mph regardless of which direction you are travelling. If it were to be coupled with a compass, and tell you, for example 65 mph, Northwest, you would then have a velocity. Speed is what is known as a scalar, since it doesn't contain any of the direction information. Velocity is what is known as a vector quantity, since it contains the direction component as well.
