Quantum Mechanics

The grisly murder of a journalist couple last Friday only further intensified the horror of life in this city punctuated by what we can call psychopathic peekaboo. A hardworking man returned home at 2:00 am after a long day's work and then death popped out ...  

One of the most mind-blowing areas of quantum mechanics is entanglement: two or more particles separated in space can have physical properties that are correlated. A measurement performed on one particle will tell us the result of the same measurement ...  

Vancouver, Canada -- Tantalizing hints of the elusive Higgs boson! Neutrinos that appear to travel faster than light! New particles! The mere inkling of a particle physics discovery gets the globe buzzing, and 2012 is shaping up to be another big year for particle physics news. Scientific leaders from laboratories around the world will present the latest particle physics findings and give a look at what's next at the annual meeting of the...  

One of the most mind-blowing areas of quantum mechanics is entanglement: two or more particles separated in space can have physical properties that are correlated. A measurement performed on one particle will tell us the result of the same measurement taken on an entangled particle. Entanglement is important but difficult to study, both in terms of a theoretical understanding and doing experiments. While...  

In 1927, Werner von Heisenberg documented what he referred to as an “Uncertainty Principle” governing quantum mechanics. The Uncertainty Principle holds that an observation cannot precisely reveal both the position of a particle at a point in time and its momentum. The more the...

Below is what happened in search today, as reported on Search Engine Land and from other places across the web. From Search Engine Land: The Paid Search Uncertainty Principle In 1927, Werner von Heisenberg documented what he referred to as an “Uncertainty Principle” governing quantum mechanics.

QUANTUM PHYSICS: Semiconductor chip converts laser to visible quantum fluidLaser Focus worldBy Gail Overton University of Cambridge (Cambridge, England) researchers can see quantum mechanics at work with the naked eye. They have developed a semiconductor chip that tightly traps laser light in the vicinity of electrons inside microscopic ...  

Quantum entanglement is such a mainstay of modern physics that it is worth reflecting on how long it took to emerge. What began as a perceptive but vague insight by Albert Einstein languished for decades before becoming a branch of experimental physics and, increasingly, modern technology.Einstein s two most memorable phrases perfectly capture the weirdness of quantum mechanics. I cannot believe that God plays dice with the universe...  

Boffins spin up positronium A group of researchers at University of California Riverside hopes to chip away at one of physics’ ‘question of questions’ – why the blazes we’re here at all. Their hope is to make electron/positron pairs live long enough to measure the positron’s mass and find out if it’s different to the electron.…  

Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure cloud computing can be achieved using the principles of quantum mechanics. They have performed an ...  

In physics the Heisenberg uncertainty principle asserts a limit in our ability to simultaneously know certain facts, such as the position and speed of a particle. The theory that captures this idea is a probabilistic theory: in quantum mechanics only the ...  

The presumed existence of the Higgs boson particle- or as it is known colloquially and much to the chagrin of proper scientists, the God particle- promises to bestow upon humanity a huge level up when it comes to understanding the origins of the ...  

The answer to one of the most exciting questions in particle physics seems almost close enough to touch: Scientists have observed first signs of the Higgs boson and now believe that they will soon be able to prove the existence of the elementary particle they have been trying so hard to isolate.  

The ‘God particle’, hailed as the holy grail of physics, may have been glimpsed for the first time. Excited scientists at the Large Hadron Collider – the world’s biggest atom smasher – are expected to announce today that they have spotted the ...
