Who cares?
WHO CARES ABOUT COSMOLOGY?
Particle physicists:
- Is there dark matter? Massive neutrinos, wimps, axions or something else?
- Did inflation happen? Can we learn about physics at very high energies?
General relativists:
- Did inflation produce gravity waves?
- What is the geometry of the Universe?
Numerical simulators:
- Only need to run the code once, not for umpteen cosmological models
People on the street
- Will there be a big crunch?
- How did it all begin?
- Are there infinitely many other stars?
Observers:
- What is the correct age, distance and size for the objects being studied?

The cosmic plan:LECTURE 1: Cosmology primer: Review of the basics of modern cosmology (basic cosmological storyline, inflation, nucleosynthesis, recombination, structure formation, etc) to get everybody up to speed on the foundations underlying the other lectures.
LECTURE 2: Cosmic microwave background: The basics of acoustic oscillations, how different cosmological parameters affect the CMB, summary of current and upcoming experiments.
LECTURE 3: Galaxy clustering: The basics of structure formation, how different cosmological parameters affect the matter power spectrum P(k), summary of current and upcoming galaxy surveys.
LECTURE 4: Other cosmological probes, outlook: Gravitational lensing, Lyman alpha forest, supernovae Ia, latest constraints on cosmological parameters, open questions, my speculations about what will be exciting areas for future research.

They hunted till darkness came on, but they found Not a button, or feather, or mark, By which they could tell that they stood on the ground Where the Baker had met with the Snark.
In the midst of the word he was trying to say, In the midst of his laughter and glee, He had softly and suddenly vanished away For the Snark was a Boojum, you see.

Beyond cosmological parameters, summary:Test the underlying physics rather than assuming itCosmological functions rather than cosmological parametersMeasure the free functions rather than parametrizing them in a way involving untested physical assumptions - a form of data compression
Do observations disagree with each other or with theory?
Data => Cosmological functions <= Theory
