"When X-rays interact with matter, they do one of three things: Pass through the object Get absorbed by the object Scatter from the object"

"Because of the increasing number of scientists who study the nervous system, several prominent neuroscience organizations have been formed to provide a forum to all neuroscientists and educators."

"elepresence refers to a set of technologies which allow a person to feel as if they were present, to give the appearance of being present, or to have an effect, via telerobotics, at a place other than their true location."

"The device feels just like scanning a real patient, so is intuitive and familiar to the user, allowing them to fully concentrate on the data."

"This new technology, called augmented reality, blurs the line between what's real and what's computer-generated by enhancing what we see, hear, feel and smell."

"Smartphones, iPads, mobile health (mHealth) apps, remote monitoring devices, cloud-based computing, and other technologic advances are continuing to rewrite the script for healthcare delivery for both patients and physicians, so much so that Forbes already has declared 2013 as the year of digital health. Consider that 60% of physicians accessed health content online using their mobile phones, and 44% turned to tablet computers, according to the 2012 comScore Physician Mobile Survey."

"To call the evolution of the computermeteoric seems like an understatement. Consider Moore's Law, an observation that Gordon Moore made back in 1965. He noticed that the number of transistors engineers could cram onto a silicon chip doubled every year or so. That manic pace slowed over the years to a slightly more modest 24-month cycle."

"CPU clock speed for a single cpu has been fairly static in the last couple of years  - hovering around 3.4Ghz. Of course, we shouldn't fall completely into the Megahertz myth, but one avenue of speed increase has been blocked:"

"Moore's law is the observation that, over the history of computing hardware, the number of transistors on integrated circuits doubles approximately every two years. The law is named after Intel co-founder Gordon E. Moore, who described the trend in his 1965 paper.[1][2][3] His prediction has proven to be accurate, in part because the law is now used in the semiconductor industry to guide long-term planning and to set targets for research and development.[4]"

"Our world is full of integrated circuits. You find several of them in computers. For example, most people have probably heard about the microprocessor. The microprocessor is an integrated circuit that processes all information in the computer. It keeps track of what keys are pressed and if the mouse has been moved. It counts numbers and runs programs, games and the operating system. Integrated circuits are also found in almost every modern electrical device such as cars, television sets, CD players, cellular phones, etc. But what is an integrated circuit and what is the history behind it?"
