Emotiv - Brain Computer Interface Technology. One clock with two times: When quantum mechanics meets general relativity. The unification of quantum mechanics and Einstein's general relativity is one of the most exciting and still open questions in modern physics.
General relativity, the joint theory of gravity, space and time gives predictions that become clearly evident on a cosmic scale of stars and galaxies. Quantum effects, on the other hand, are fragile and are typically observed on small scales, e.g. when considering single particles and atoms. That is why it is very hard to test the interplay between quantum mechanics and general relativity. Now theoretical physicists led by Časlav Brukner at the University of Vienna propose a novel experiment which can probe the overlap of the two theories. The focus of the work is to measure the general relativistic notion of time on a quantum scale. The findings were recently published in Nature Communications. Time in general relativity. Quantum mechanical transistor. Not science fiction any more Sandia's quantum mechanical transistor may increase computer speed and sensor accuracy ALBUQUERQUE, N.M. -- Improvements in the transistor of the future may not rely on decreasing its size but rather on a radical change in operation made possible by a quantum mechanical transistor created at Sandia National Laboratories.
The quantum mechanical transistor is the equivalent of turning on a light bulb without closing a switch: Electrons "tunnel" from path to path through a barrier that, according to classical physics, is impenetrable. The process takes place with extreme rapidity. The term "tunneling" may bring to mind moles or the highway department, but physicists use it to describe an effect in which particles, like electrons, appear in places where by rights they should not be able to go.

January 1, 2015. Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. Particles faster than light: Revolution or mistake? So, the day after news broke of a possible revolution in physics — particles moving faster than light — a scientist leading the European experiment that made the discovery calmly explained it to a standing-room- only crowd at CERN, the giant particle accelerator straddling the Swiss-French border.
The physicist, Dario Auterio, made no sweeping claims. He did not try to explain what the results might mean for the laws of physics, let alone the broader world. How to Detect Lies - body language, reactions, speech patterns. Interesting Info -> Lying Index -> How to Detect Lies Become a Human Lie Detector (Part 1) Warning: sometimes ignorance is bliss.
After gaining this knowledge, you may be hurt when it is obvious that someone is lying to you. The following deception detection techniques are used by police, forensic psychologists, security experts and other investigators. Introduction to Detecting Lies: This knowledge is also useful for managers, employers, and for anyone to use in everyday situations where telling the truth from a lie can help prevent you from being a victim of fraud/scams and other deceptions.
This is just a basic run down of physical (body language) gestures and verbal cues that may indicate someone is being untruthful. If you got here from somewhere else, be sure to check out our Lie Detection index page for more info including new research in the field of forensic psychology. 9501011v2.pdf (application/pdf Object) m13.pdf (application/pdf Object) Yakir a.pdf (application/pdf Object) An Essay by Einstein. "How strange is the lot of us mortals!
Each of us is here for a brief sojourn; for what purpose he knows not, though he sometimes thinks he senses it. But without deeper reflection one knows from daily life that one exists for other people -- first of all for those upon whose smiles and well-being our own happiness is wholly dependent, and then for the many, unknown to us, to whose destinies we are bound by the ties of sympathy. A hundred times every day I remind myself that my inner and outer life are based on the labors of other men, living and dead, and that I must exert myself in order to give in the same measure as I have received and am still receiving...
"I have never looked upon ease and happiness as ends in themselves -- this critical basis I call the ideal of a pigsty.
