The Library of Congress has acquired The Seth MacFarlane Collection of the Carl Sagan and Ann Druyan Archive, and has begun to catalog and digitize the materials in it, posting them to the library’s website. The scanned materials include Sagan’s personal papers, and are divided into three categories: models of the cosmos throughout history; history of the possibility of life on other worlds; Carl Sagan’s life and contributions to science and society.

About the Book: The New York Times best-selling author of Physics of the Impossible, Physics of the Future and Hyperspace tackles the most fascinating and complex object in the known universe: the human brain.
For the first time in history, the secrets of the living brain are being revealed by a battery of high tech brain scans devised by physicists. Now what was once solely the province of science fiction has become a startling reality. Recording memories, telepathy, videotaping our dreams, mind control, avatars, and telekinesis are not only possible; they already exist.

BYU engineer Dah-Jye Lee has created an algorithm that can accurately identify objects in images or video sequences — without human calibration.
“In most cases, people are in charge of deciding what features to focus on and they then write the algorithm based off that,” said Lee, a professor of electrical and computer engineering. “With our algorithm, we give it a set of images and let the computer decide which features are important.”
