Relativity (Day 2) Einstein Look Alike Day
If you missed today:
1. We had a relative discussion about time and length with your twin in a space ship going half the speed of light. Note that your time on Earth would be going 15% faster than your twins time in space and if you witnessed your twin's 100 meter spaceship go by, you would measure it as 85 meters long.
Here is a cool youtube video that explains all of Einstein's theories as elementary as it can. Click here or same video below.
Can do the cannot tell if your moving or the other person is moving demo in the classroom (student blind folded during demo on a table that is lifted high by fellow classmates until the blind folded student's head hits the ceiling) see video at bottom of this page for examples. If you are a student in class this year or plan on taking the class, do NOT watch video until you have a chance to experience it for yourself (or just do not ruin it for fellow classmates).
Note the Fab Five Formula #1 that v = s / t and if v = c then c = s/t so if c stays constant then if t shrinks then s must also in order for c to stay the constant speed of light. example: c = 12/4 = 9/3 = 6/2 = 3/1 = 1.5/0.5 (all X 10^8 m/s).
