- Fall 2014 Packet 1: Remember: Coefficients have no units. They are just pure math. Constants are measured numbers. They DO have units (sometimes crazy units)!
-
- Fall 2014 Packet 1:
-
- Fall 2014 Packet 1: For now let’s just say keep it to 3 or 4 non zero digits in your answer. Don’t write all the numbers that are on your calculator.

- Fall 2014 Packet 1: problem 1.1.7
-
- Fall 2014 Packet 1:
-
- Fall 2014 Packet 1: From a couple of years ago. Same problem as 1.1.7 but explanation in more detail.

-
- Fall 2014 Packet 1: Another way of looking at 1.1.7 (i think this space-time graph makes the most sense.
-
- Fall 2014 Packet 1: another example of the space time graph.
-
- Fall 2014 Packet 1: another example
-
- Fall 2014 Packet 1: It’s important in physics to know these basic kind of numbers so you can see if your answer (or my question) makes any sense.
-
- Fall 2014 Packet 1: We might use pico meters to measure the width of the nucleus of a Lithium atom.
-
- Fall 2014 Packet 1: Some metric stuff
-
- Fall 2014 Packet 1: The official “meter” in Paris. It is no longer used. Now we base the meter on the speed of light.
-
- Fall 2014 Packet 1: The official kilogram
-
- Fall 2014 Packet 1: Working with the official kilogram
-
- Fall 2014 Packet 1: How we store the official kilogram. There are a couple of copies in different parts of the world. One is even in the US!
-
- Fall 2014 Packet 1: The cesium clock that we base the measure of one second on. In 1967, the 13th General Conference on Weights and Measures first defined the International System (SI) unit of time, the second, in terms of atomic time rather than the motion of the Earth. Specifically, a second was defined as the duration of 9,192,631,770 cycles of microwave light absorbed or emitted by the hyperfine transition of cesium-133 atoms in their ground state undisturbed by external fields.

- Fall 2014 Packet 1: Plank length is the smallest length possible in the universe. You can’t cut it in half. Isn’t that weird. It’s pretty darn small. It is the pixel of space.
-
- Fall 2014 Packet 1: Plank length used in String Theory.
-
- Fall 2014 Packet 1: We went back outside for 1.1.8. We changed the procedure from last year.
-
- Fall 2014 Packet 1: 1.1.8
-
- Fall 2014 Packet 1: 1.1.8
-
- Fall 2014 Packet 1: 7th hour outside doing 1.1.8

-
- Fall 2014 Packet 1: We finally got our notebooks on Friday and started a few notes. Make sure you color in the upper outside comers and put a “1” in the corner.
-
- Fall 2014 Packet 1: We need reference points since nothing in the universe is standing still. When I ask how fast are you moving. You always ask . . . ” In relation to what?”
-
- Fall 2014 Packet 1: Michaelson and Morley tried to find the ether (aether) in the 1880’s.
-
- Fall 2014 Packet 1: they used an interferometer.
-
- Fall 2014 Packet 1: their interferometer
-
- Fall 2014 Packet 1: they were trying to detect the ether wind.
-
- Fall 2014 Packet 1:
-
- Fall 2014 Packet 1:
-
- Fall 2014 Packet 1: The idea behind the interferometer
-
- Fall 2014 Packet 1: No matter how accurate or what the orientation the experiment kept giving the same result. There was no indication of enter wind. They finally concluded that there was no enter. Today, the idea of “the ether” is making a comeback. They are wondering if it really is what makes up space. Since they are finding that there really is no such thing as a vacuum.
-
- Fall 2014 Packet 1: Definition of standing still.
-
- Fall 2014 Packet 1: The 5 velocities that you STILL have even if you are sitting at your desk VERY still.
-
- Fall 2014 Packet 1: Galactic year.
-
- Fall 2014 Packet 1: Dimensions vs. units
-
- Fall 2014 Packet 1: Unit analysis Physics style

-
- Fall 2014 Packet 1: Remind me to talk about the Forum (no, it’s not a cult).
-
- Fall 2014 Packet 1: The “New” Cantina is healthier than ever.
-
- Fall 2014 Packet 1: It’s a new morning for the Cantina. What a delicious balanced, and healthy breakfast. Now if you’ll just eat it.
