could be affected, moved, or changed without being physically affected by another object, has raised different arguments throughout history. Some believe that action at a distance would describe all the uncertainties of quantum physics and would help us understand the unknowns of quantum mechanics. There have been varies experiments that support the claims of action at a distance and those who disagree and look to disprove this concept. One of the experiments that disproves the argument is the…
where does this energy originate from? Currently, there are two prominent theories in the physics community that predict a vacuum energy. These are Quantum Field Theory and Supersymmetry, referred to as QFT and SUSY respectively. Each of these theories predicts a different value for the constant vacuum energy density (Lecture 1). According to Quantum Field Theory, in every point of space, there is a small harmonic oscillator of every possible frequency. When these oscillators are excited with…
‘The only thing compulsory is fun,’ I’d like to quote Professor Ping Koy Lam. This statement may sound dubious or lazy when claimed plainly, or perhaps a weak attempt at ‘the moral of a story’. However, to Professor Ping Koy Lam, this was exactly what led him to his accomplishments today. Professor Lam was born in Penang, Malaysia in 1967, and grew up inspired by men of science, His passion for science was deeply imprinted on him during his early youth by his brothers, father and a few…
interesting topics. In fact, there are two books I know that are written historically about espionage. “The Dark Game: True Spy Stories from Invisible Ink to CIA Moles” by Paul Janeczko and “The Code Book: The Science of Secrecy from Ancient Egypt to Quantum Cryptography” by Simon Singh are both about the history of espionage. Although The Dark Game by Paul Janeczko and The Code Book by Simon Singh are both nonfiction books about the history of espionage, the point of view, style, and tone is…
appearing everywhere, all the time, in the vacuum of quantum field theory?” The book is rich in apt analogies, as in Mr. Galfard’s description of electromagnetism as the exchange of virtual photons: “Pearls of light flash around you, exchanged between the magnet and the fridge, like a host of tiny angels dragging the two objects towards one another.” By the end, readers will have learned a great deal, although they might stumble explaining quantum field theory over cocktails. A second reading is…
Introduction Near-field communication (NFC) is a set of protocols that allow communication between two electronic devices. Most commonly this technology is used for communication between portable devices like smartphones. Even though it is a contact less system of communication, it requires that the devices are within 4 cm or 1.57-inch distance from each other (Carter & Faulkner, 2015). Basically, this technology relies on creating a low speed connection between the devices which has a very…
Millions of valiant soldiers, sailors, and airmen contributed to the Allied victory over Nazi Germany in World War II, but one of the war’s biggest heroes was a little-known British scientist who never stepped foot on a battlefield. Alan Turing was a brilliant mathematician, logician, and cryptologist who played a pivotal role in cracking the Enigma code — the system used by the Nazis to encrypt secret messages — which many experts believed was impossible to break. The intelligence gleaned from…
