C O U R S E L E C T U R E Orders of Magnitude Notes taken on December 19, 2015 by Edward Tanguay |
•
orders of magnitude in terms of money
•
1. a dollar
•
10^0 dollars
•
one Snickers bar
•
2. ten dollars
•
10^1 dollars
•
a compact disc
•
3. one hundred dollars
•
10^2 dollars
•
dinner at a nice restaurant
•
4. one thousand dollars
•
10^3 dollars
•
a nice vacation
•
5. ten thousand dollars
•
10^4 dollars
•
a new car
•
6. one hundred thousand dollars
•
10^5 dollars
•
an apartment in Paris
•
eight orders of magnitude / size scales
•
1. human being
•
about 1 meter
•
10^0 meters
•
2. planets
•
next step up in structure
•
range from 10^6 - 10^7 meters
•
the jump in orders of magnitude between the size of a man and the size of a planet is larger than the different between the price of a candy bar and a nice apartment in Paris
•
3. stars
•
10^8 - 10^12 meters
•
dwarf stars to giant stars
•
4. planetary sytems
•
our solar system
•
10^13 meters
•
5. galaxies
•
vast collections of stars
•
10^19 meters
•
a jump of nine orders of magnitude, more than from man to planet
•
6. galaxy clusters
•
groups of galaxies
•
10^22 meters
•
7. super clusters
•
clusters of clusters of galaxies
•
10^24 meters
•
8. size of universe
•
the observable universe, i.e. the bubble of light which encompasses the universe which we can see
•
but there is most likely more universe beyond even that
•
our understand now is the the universe is, in fact, infinite, on the largest scales
