1. Sources of funding for research: Grants & money from the government
2. Basic research: to understand something
3. Applied research: research with a specific goal in mind
4. Ptolemy: greek astronomer and geographer, first model for the solar system with
the earth at the center, came up with "epicycles"
5. Copernicus: polish, put sun at the center of the solar system
6. Brahe: Danish, studies funded by the king, had an island to study the solar
system, took 25 years of measurements but never analyzed the data
7. Kepler: German mathematician, Brahes assistant, analyzes the data
8. Keplers discoveries (3): 1. planets move in oval shape around the sun 2. A line
from the sun to the planet sweeps out equal areas in equal times
3. The square of the period of an orbit is proportional to the cube of the orbital radius
9. Galilei: Physicist, used a telescope, discovered 3 of jupiters moons, discovered
sun spots
10. Reflecting telescope: uses mirrors
11. refracting telescope: Uses lenses
12. Keck Telescope: uses visible and infrared light
13. Radio telescope: collects radio waves, looks at objects with a magnetic field
14. Layers of the sun: -core
-radiative zone
-convective zone
-photosphere, visible part
-chromosphere
-corona
15. Galaxy: collection of stars and planets held together by gravity
16. Position: Location relative to coordinate system
17. Velocity: Speed and direction
18. Speed: how fast
19. Acceleration: change in velocity
20. Newton's 1st Law: (Law of Inertia) an object in motion tends to stay in motion
& an object at rest stays at rest unless acted upon by an outside force.
21. Newtons 2nd Law: The acceleration of an object depends on the mass of the
1 O/ O
