  I present several simple figures to illustrate cosmology and structure
formation in a nutshell. Then I discuss the following argument: if we assume
that Omega_{Lambda} = 0 then the CMB results favor high Omega_{m} while the
supernova results favor low Omega_{m}. This large inconsistency is strong
evidence for the incorrectness of the Omega_{Lambda} = 0 assumption. Finally I
discuss recent CMB results on the slope and normalization of the primordial
power spectrum.
