Kamionkowski is a theoretical physicist, who’s research is in
cosmology, astrophysics, and elementary-particle theory. His main
focus has been on particle dark matter, inflation the cosmic
microwave background, and cosmic acceleration. His 1999 paper, A
Polarization Pursuer’s Guide inspired Professor Keating to create
the BICEP experiment. He is the William R. Kenan, Jr. Professor of
Physics at Johns Hopkins University. 00:00:00 intro 00:04:39 The
BICEP 2 Press Conference St. Patrick’s Day 2014 and how Professor
Kamionkowski inspired the BICEP collaboration and the story of the
well known cosmology paper: A Polarization Pursuers' Guide, 1999 (
https://arxiv.org/abs/astro-ph/9909281 ), the inspiration for
BICEP.  00:06:58 Did you realized the implications of your
paper for telescope design at the time? Marks’s proposition to
measure the amplitude of primordial gravitational waves, even with
a small aperture telescope. The origins of BICEP and the Simons
Observatory. 00:15:40 Optical surveys are still a cornerstone of
observational cosmology like weak gravitational lensing and
comparisons to E/ B mode curl components measurements. 00:28:50 Is
a theory of everything possible? Are physicists “lost in math”?
What to you think make good mathematical models? Little attention
has been given to alternatives to symmetries in string /
super-symmetry theories which have not been productive? Behold the
examples of Bohr and Balmer’s formula and the breakthroughs of the
20th century. The luck of 20th Century Physics. The price tags and
time scales are much bigger now. Don’t abandon the notion of
symmetry!  00:34:53 The cosmological principle; should it go
away? What would you do if it did? All models are approximations.
We have good descriptions. 00:41:00 The social contagion of Eric
Lerner and the controversy over the refutation of the Big Bang
Theory. https://iai.tv/articles/the-big-bang-didnt-happen-auid-2215
Does it make you re-evaluate the standard model of the Universe?
00:45:5l0 About the Hubble Tension. What is it? Why worry? Or not!
00:56:00 Professor Kamionkowski’s explanation of early Dark Energy
and his 2018 paper. 00:59:10 Anti-helium and anti-matter clouds
01:01:10 What theoretical physics “crisis” or anomalies should we
most focus on? How do you choose? Let’s not all focus on the
same problems! What about the cosmic optical background found by
the New Horizons Long Range Reconnaissance Imager? 01:10:35 Is
there an Axion Persurer’s Guide to be written? 01:12:00 What is the
status of the theory of Inflation and where will it go? A field
Marc helped initiate. 01:17:50 First existential question: What
would you put on your monolith? 01:21:20 What have you changed you
