Fun with Qubits →
If you look at a cylindrical block from the bottom, you see a circle. If you look at it from the side you see a square.
Imagine a cylindrical block that is spinning around amazingly fast. When you look at it, it stops spinning and snaps into either a circle or a square.
This is similar to how a qubit will behave. Whereas a normal bit has a value of either one or zero. A qubit is both. A qubit...

What are the practical complications of turning... →
Question:
Lets just say I had practically inifinte energy. How do I go about turning this into a stream of protons? Dont hold back on the quantum field theory. Smashing existing particles together & filtering out what we want(protons) is not a good enough answer.
Answer:
The first practical complication is that you cannot (as far as we know) create matter without also creating an equal...

Big Bang theory challenged by big chill →
The start of the Universe should be modeled not as a Big Bang but more like water freezing into ice, according to a team of theoretical physicists at the University of Melbourne and RMIT University.
Read this article, it’s interesting.

Painless Injections →
In designing this jet-injection mechanism, the engineers relied on what’s known as a Lorentz force actuator (Image 3). The Lorentz force actuator in this case is a small permanent magnet surrounded by a coil of wires. The coil of wires, or solenoid, is part of a piston system that is separate from the permanent magnet which lies in the center. If we recall from high school physics, we know...

We've found the Higgs Boson: What next?
Dark Matter
The LHC is about to have a $1.82 Billion upgrade to research dark matter.
TheAge reports:
It might have only just found the elusive ”God particle”, but the Large Hadron Collider at the CERN laboratory, near Geneva, is to have a $A1.82 billion upgrade at the end of the decade to investigate the mystery of dark matter.
Scientists believe dark matter holds the universe...

New Camera Detects Cancer Cells →
“To catch these elusive cells, the camera must be able to capture and digitally process millions of images continuously at a very high frame rate,” said Bahram Jalali, who holds the Northrop Grumman Endowed Opto-Electronic Chair in Electrical Engineering at the UCLA Henry Samueli School of Engineering and Applied Science. “Conventional CCD and CMOS cameras are not fast and...

Why Scientists are excited about the Higgs Boson,...
anticapitalist:
Late last year, an experiment showed that neutrinos were going faster than the speed of light. This experiment had reached a 6-sigma level of confidence, but yet most scientists were highly skeptical. It was later proven that this experiment was wrong because of a faulty setup.
But this Higgs Boson experiment had only reached a 5-sigma level of confidence, but scientists are...

WatchThis is a video entry in the Flame Challenge.
The Flame Challenge is a competition in which scientists across the world had to answer the question “What is a flame” such that an 11-year old could understand it.
This was one of my favorite entries.

Overview (of computing)
ibmdeepblue15:
In the earliest days of computing, the game of chess represented a challenge to the science and research community who sought to explore the calculating capabilities of these machines. Chess, while a very structured and focused game, requires a certain level of intelligence that some humans never master.
IBM took on this challenge and Friday May 11, 2012 marks the 15 year...

Two 70-year-old papers by Alan Turing on the theory of code breaking have been released by the government’s communications headquarters, GCHQ.
It is believed Turing wrote the papers while at Bletchley Park working on breaking German Enigma codes.
A GCHQ mathematician said the fact that the contents had been restricted “shows what a tremendous importance it has in the foundations of...
