High Temperature Superconductivity, One Atom at a Time
32	For over twenty years, high temperature superconductivity has defied explanation. Amazingly complex electronic interactions and resultant material properties have enticed many to try. Has this complexity masked a simpler picture? New experiments answer "perhaps." BY ERIC HUDSON

Exoplanet Mass, Radius, and the Search for Habitable Worlds
40	Over 300 exoplanets are known to orbit nearby sun-like stars. Yet, little is known about exoplanets beyond their minimum masses and orbit characteristics. Fortunately, a subset of exoplanets go in front of their stars as seen from Earth, enabling us to answer the question: "What are exoplanets made of?" BY SARA SEAGER

The Physics of Energy: Introducing 8.21
44	This Fall, the Department of Physics debuts an exciting and timely class, The Physics of Energy [8.21]. Co-created by Center for Theoretical Physics faculty Bob Jaffe and Wati Taylor, for the benefit of all MIT undergraduate majors, its premise is that a clear grasp of the basic physics underlying energy processes is essential to achieving real solutions to the ever-growing challenges of our current energy situation.
