Bored, Hungry, Tired.

"As per usual..?"

Not much to say or do.

I did edit my story, again, somehow. Even though I thought it was my last edit. Whatever.

Poetry, is soon, too. Too soon.

Physics in a nutshell:

1) Aristotle
2) Aristachus (Arid Starch USA)
3) Ptolemy (Some guy.)
4) Copernicus
5) Tycho Brahe
6) Johannes Kepler
7) Galileo Galilei
8) (Sir) Mr. Isaac Newton
9) Albert(o) Einstein

Too tired to care.

Law for Gravitation: F = (G (m1) . (m2)) / r^2

Where F is in Newtons
Where G is a constant with dummy dimensions
Where m1 + m1 is in Kilograms
Where r is displacement between the centre of gravity of the two bodies in metres.

Keplar's Laws of Planetary Motion
1) Law of ellipses
Planets revolve in Ellipses in the Solar System
2) Law of Areas
Radii of an ellipse "sweep" out equal areas in equal times
3) Law of...something. Relationship between distance and time.
T^2/D^3 = k

Where k is 1 for all objects in our Solar System

That is; T^2 is proportional to D^3

There T is time in light years (?) and D is distance/displacement in AU(s).

Limitations of models:

Generally crap telescopes; only had naked eye vision (So to speak)

Poor understanding of motion and physics pre-Newton. Which means that a heliocentric, heliostatic model doesn't "feel" right.

Dogmatic Christian Church People shouting "NO YOU'RE WRONG. YOU DESERVE A HOUSE ARREST DICTATED BY OUR GOD." => Galileo is imprisoned, Science takes a step backward, technically, through the denial of a great thinker. Just like light is the abscence of darkness and vice versa. Which means that yet again, Religion has screwed something up.

Religion = Human Construct = "Creation is the work of a lifetime, destruction, the work of an afternoon."

Moving on.

HR Diags:

White star => MS => Super Giants => Giants => MS => Neutron Star/Black Hole, as dictated by the graph evolution series thing, and my eidetic memory.

Oops. I looked at the book wrong. Get rid of Super Giants, relabel Giants as Red Giants, and that's the evolutionary track for a 1SM star.

Luminosity rel. color rel. temperature.

That is, they're all linked. As you move towards the top right of the HR Diag, stars generally get bigger, because bigger stars = more SA = more need for energy = more temperature, etc. etc.

Gravity and Pressure are in opposition to one another.

As temperature goes up, the more dominant wavelength are the shorter ones.

So, Temperature is inverse prop. to wavelength.

Ah. The third law is called "Law of Periods"

Lastly, because I missed it. Similar to Gravitation, luminosity of a star is inverse prop. to the square of the distance from the centre of that star. It's exactly the same for Gravity. All good.

G is incredibly small, btw.

Anyway, that should cover it all.

Hoping all my memorised info was right, and to the syllabus. Also that I didn't forget anything.
