"Dark Energy and Cosmic Sound"
ABSTRACT: The acoustic oscillations of the photon-baryon fluid in the early universe
imprints a signature of known scale into the clustering of matter and galaxies at recent
times. Large galaxy redshift surveys can recover this scale as a set of oscillations in the
power spectrum, thereby measuring the Hubble parameter and angular diameterdistance
relation as a function of redshift. Such cosmologicalmeasurements could permit precise
and robust constraints on the dark energy equation of state. I will describe the prospects
for detecting and utilizing the acoustic oscillations within current and future galaxy surveys.

"SpaceX and the Falcon Launch Vehicle:
Private Investment Aimed at Reducing the Cost and
Reliability of Access to Space"
ABSTRACT: Space Exploration Technologies (SpaceX) under private
developing a family of launch vehicles aimed at addressing a long
the high cost yet low reliability of access to space. The first
product, Falcon, is a light
class launcher capabile of lifting 1500 pounds to LEO for a price of
$5.9M. Our maiden
flight will lift the DOD's TacSat-1 spacecraft from Vandenberg Air
Force Base mid year.
The talk will provide background on the company and the motivation of
our goal and
also provide insight into the Falcon family of launchers.

"Extending Laser Spectroscopy via Quantum Correlation, Coherence and Control"
ABSTRACT: Quantum correlation and entanglement is a concept
which goes to the
heart of quantum mechanics, e.g. the EPR paradox and quantum eraser.
of photon correlation techniques will be seen to yield new devices
from quantum computing t
o magneto spectroscopy and protein dynamics . Likewise, quantum
coherence and control
yield new insights and discoveries from lasing without inversion and
ultraslow light to new kinds
of microscopy and spectroscopy. The combination of these three
features of quantum mechanics
is especially powerful and holds promise for opening whole new areas
of chemical and bio-physics.
The rapid detection of anthrax endospores is one example.
