ABSTRACT
Computer science serves to isolate programs (and programmers) from knowledge of the underlying mechanisms used to manipulate information, however it will not be possible to maintain this fiction in the approaching limit in which the number of information-bearing degrees of freedom in a computer becomes comparable to the number of physical ones. I will explore the implications of aligning these physical and computational descriptions for improving the performance, scalability, and ultimately the relevance of information technologies for some of the grandest global challenges. Examples will be drawn from work on conformal computing, interdevice internetworking, and digital fabrication.
Speaker: Neil Gershenfeld
Prof. Neil Gershenfeld is the Director of MIT's Center for Bits and Atoms. His unique laboratory is breaking down boundaries between the digital and physical worlds, from creating molecular quantum computers to virtuosic musical instruments. Technology from his lab has been seen and used in settings including New York's Museum of Modern Art and rural Indian villages, the White House and the World Economic Forum, inner-city community centers and automobile safety systems, Las Vegas shows and Sami herds. He is the author of numerous technical publications, patents, and books including Fab, When Things Start To Think, The Nature of Mathematical Modeling, and The Physics of Information Technology, and has been featured in media such as The New York Times, The Economist, and the McNeil/Lehrer News Hour. He is a Fellow of the American Physical Society, and has been selected as a CNN/Time/Fortune Principal Voice and by Prospect/FP as one of the top 100 public intellectuals. Dr. Gershenfeld has a BA in Physics with High Honors and an honorary Doctor of Science from Swarthmore College, a Ph.D. from Cornell University, was a Junior Fellow of the Harvard University Society of Fellows, and a member of the research staff at Bell Labs.

MADE IN IBM LABS: In a recent paper published in the journal Science, IBM researchers describe a new milestone in nanotechnology: the ability to measure the force required to move individual atoms. Their findings are an important step for understanding what types of atoms are best suited for building different kinds of nanoelectronic devices, based on how strong or weak of a bond they can form on different surfaces.
The ability to control atoms and move them around on a surface was first discovered by an IBM researcher nearly 20 years ago -- an achievement that has been hailed as the "Kittyhawk of Nanotechnology." But until today, nobody has known the exact force required to move atoms on a surface: an absolutely critical understanding if we are to build Lilliputian computer chips and storage devices from the atom up.
The problem is akin to what scientists and engineers needed to learn about construction at macroscopic sizes many decades ago. For example, building a modern bridge would be impossible without first measuring the strength of different materials, understanding the relevant forces, and comprehending how everything interacts. In the nanotechnology realm, to make structures that you want to remain rigidly in place you would use strongly bonded ("sticky") atoms while for groups of atoms that need to move you would use atoms held in place only by weak chemical bonds.
IBM is no stranger to working with atoms. Two IBM scientists won the Nobel Prize for their invention of a specialized microscope that could "see" individual atoms for the first time. And in 1989, in the same Silicon Valley lab where today's breakthrough took place, an IBM scientist was the first to move atoms on a surface, spelling I-B-M in Xenon atoms. More recently, IBM has demonstrated the potential to store data in individual atoms or small clusters of atoms, and that single molecules may work well as switches for future computer chips. As these breakthroughs before them, IBM continues to drive the future of atom scale research.
This presentation illustrates the parts of an atom. It shows how the atom is made of electric charges in the form of protons and electrons. Other related topics include atoms. atomic structure, Coulombs Law of Charges, the force between charges, the unit charge (coulomb), forces between sub-atomic particles, ionization, ions, ionic bonding, the strong nuclear force, the nucleaus, protons, and neutrons.
Episode 1 of In Search of Giants: Dr Brian Cox takes us on a journey through the history of particle physics. In this episode we learn that the Greeks knew about atoms and how Mendeleyev's periodic table was among the first clues that the atom had a deeper structure.
