As a result, our picture of how the universe came into being and how it evolves is approaching near-perfect focus: after thousands of years of thought, it seems as though we may be a few short decades away from understanding the physical nature of our ultimate origins. Recently, an exquisite set of observations of the afterglow of the big bang (known as the cosmic microwave background) has made our image of the early universe significantly crisper. These data have confirmed most of our standard cosmological model, but at the same time have raised intriguing new questions. I will review our basic understanding of cosmology and describe how observations of the cosmic microwave background both confirm and challenge our current understanding of the universe.The colloquium will begin promptly at 4:30 p.m. in Science Center 199.

Founders Day: Premiere of \"Peace Talks\" for Chorus and Orchestra

Founders Day Concert
with the Swarthmore College Chorus and the Swarthmore College Orchestra

On Fri., Dec. 5, the College will celebrate the final event of its Sesquicentennial Year with a Founders Day concert performed by the College’s chorus and orchestra. The concert will begin with a universal moment of silence from 8:05 to 8:06 p.m. that the entire Swarthmore community is invited to observe—and  that offers us time to reflect, with deep gratitude, on the vision and unwavering commitment of our founders and on the many who built on this vision over the last 150 years. 

The concert will also feature the premiere of Peace Talks, a piece by composer James Matheson ’92 and librettist Jared Green ’92 that was specially commissioned to celebrate our sesquicentennial. Works for orchestra by Sibelius and Fauré, and choral works from a variety of American composers and traditions, will also be performed. 

Please join us for a live audiostream of this concert at http://swat150.swarthmore.edu/listen-founders-day-concert.html.

In particular we will highlight the AdS/CFT approach pioneered in string theories, for studying two dimensional near black hole horizon quantum conformal field theories relevant to four dimensional black hole thermodynamics.Since the discovery that black holes exhibit thermodynamic properties by Hawking and his contemporaries, they have provided a unique insight into the highly contested research field of quantum gravity. One of their more interesting thermodynamic features is that of holographic-scaling of black hole entropy. In other words, a black hole’s two dimensional horizon area encodes information about the quantum nature of the four dimensional spacetime in its immediate vicinity. This principle of holographic-scaling is one of the corner stones of the duality between gravity and lower dimensional quantum field theories, also known as the AdS/CFT correspondence of string theory. Applied to black holes, the idea of this correspondence is to construct lower dimensional quantum (gravitational) field theories, which are dual to the four dimensional black hole in its near horizon regime. This holographic approach to quantum gravity allows for the use of lower dimensional quantum field theoretic techniques to compute four dimensional quantum gravitational quantities.The colloquium will begin promptly at 4:30 p.m. in Science Center 199.Light refreshments will be served

\"Applied String Theory\"

A long-standing challenge in theoretical physics has been achieving an understanding of gravity consistent with the principles of quantum mechanics. This question is not a mere mathematical curiosity, but is crucial for describing the beginning of the universe and the physics of black holes. String theory has emerged as the leading candidate to unite Einstein's theory of gravity and quantum mechanics, and has given us insights into the microscopic structure of black holes. Unexpectedly, the ideas and techniques of string theory have also led to new ways of thinking about other branches of physics. In particular, they have improved our understanding of strongly interacting quantum systems -- such as the primordial soup of quarks and gluons present in the earliest seconds of the universe and the behavior of unconventional materials such as high temperature superconductors.

In this talk, I will describe how string theory leads to surprising new tools for probing a number of strongly coupled quantum systems difficult to analyze using traditional methods.
