Sometime on Nov. 3, the supercooled magnets in sector 81 of the Large Hadron Collider (LHC), outside Geneva, began to dangerously overheat.

A bit of baguette

Apparently, a passing bird may have dropped the chunk of bread on an electrical substation above the accelerator, causing a power cut

While most scientists would write off the event as a freak accident, two esteemed physicists have formulated a theory that suggests an alternative explanation: perhaps a time-traveling bird was sent from the future to sabotage the experiment.

they

have published several papers over the past year arguing that the CERN experiment may be the latest in a series of physics research projects whose purposes are so unacceptable to the universe that they are doomed to fail, subverted by the future.

setbacks to the LHC occur because of "reverse chronological causation," which is to say, sabotage from the future.

The theory

is based on complex mathematics

New quantum algorithm helpes solving big problems.

Tue, 10 Nov 2009 03:02:18 GMT

clipper's remarks: “Large-scale linear systems of equations exist in many fields, such as weather prediction, engineering, and computer vision”, says Harrow. “Quantum computers could supply serious improvements for these and many other problems. For example, a trillion-variable problem would take a classical computer at least a hundred trillion steps to solve, but using the new algorithm, a quantum computer could solve the problem in just a few hundred steps”.

The solution could also be applied to other complex processes such as image and video processing, genetic analyses and even Internet traffic control.

Sounds pretty good to me!

One of the most basic problems in maths is solving very large linear equations. There's nothing mysterious about them, they simply take time and the more variables there are, the longer it takes. Even a supercomputer would struggle to solve a system of equations that has a trillion variables.

Aram Harrow at the University of Bristol and colleagues from MIT in the United States have discovered a quantum algorithm that solves large problems much faster than conventional computers can.

To understand how the quantum algorithm works, think of a digital equaliser in a stereo CD player. The equaliser needs to amplify some components of the signal and attenuate others. Ordinary equalisers employ classical computer algorithms that treat each component of the sound one at a time.

By contrast, a quantum equaliser could employ a quantum algorithm that treats all components together at once (a trick called 'quantum parallelism'). The result is a huge reduction in the difficulty of signal processing.

Primary schools across the state set to go bilingual

Primary schools across the state set to go bilingual

CHILDREN in their first years of primary school will be required to learn and use an Asian language in the state's first bilingual classes.

Starting in kindergarten, students will take up Mandarin, Korean, Japanese or Indonesian for at least 90 minutes a day, across every class except English and mathematics.

The Rees Government committed $2.25 million over four years to the Bilingual Schools Program.

"Young children have a far better chance of developing bilingual fluency from an early age," Education Minister Verity Firth said yesterday.

"These bilingual schools will teach two classes of students in kindergarten and Year 1 for 90 minutes each day and eventually will be expanded to all grades," Ms Firth said.

Mandarin-speaking volunteers will assist teachers in class.

PI Fun Facts

PI Fun Facts

Important points and notes:

π=3.14

circumference ≈ 3.14 x diameter

It must be noted that 3.14 is an approximate and is a rounded off value of π.

That wasn’t very hard. Keep going. As we break it down you will find it is easy. You’ve got the idea of what PI is now, so what are you going to use it for?

What do we need PI for?

Come on now! In the first stage it is about finding the measurement around a circle. There are circles all around us. We need to be able to measure these circles for many reasons. It starts with a coin. A coin is round. We need to know the measurement of its circumference so we know what size to make the slots on the soda machines.

Some Fun Facts and Things to Know About PI:

Did you know that π is the sixteenth letter in the Greek alphabet? It’s true. There must be an interesting connection here. I wonder if anyone has looked into it. If anyone knows, let us know.

The exact value of PI cannot be calculated.

Always profit - this is what arbitrage betting is all about. An arbitrage opportunity in sports betting means that one is able to bet on all possible outcomes of a certain match at odds that guarantee profit regardless of who wins that match. Arbitrages are also known as surebets or surewins. This is not gambling - it's just a market phenomenon based on pure mathematics and occurs when bookmakers have different opinions on the result of a certain game or event.
