See if this problem sounds familiar. A language learner, Andy, works hard memorizing a vocabulary word or some other bit of language, just as a good student should. He then gets a chance to speak to someone – an actual conversation – but while trying to remember what he studied, it seems to have disappeared completely.

It gets worse. Andy begins to think that this event is a sign that he is not good at learning language. As a result, a short time later, he gives up thinking that learning a language is just not for him. Andy believes “he doesn´t have what it takes”.

False.

Language is not something you learn just to score high on a test. In fact, learning a language is not like learning math or science; rather, think of it more like basketball.

Here is a fictitious story to help you see why. Imagine Michael Jordan is teaching a basketball class. Now imagine that he tells everyone he has written “the book” on basketball – “How to Play Basketball”, by Michael Jordan. Now imagine that he has written a dozen chapters, and that all the chapters together contain every concept and rule of basketball. There are chapters on dribbling, passing, shooting, and, of course, dunking. He further explains that every Friday he will have a test so that he can ensure that students have learned all the information.

Imagine once more that the students, loving Michael Jordan the way they do, all studiously memorize the book, prepare for every test, and, in fact, get perfect scores. On the last day of the class, Michael Jordan puts a basketball in front of the class and states, “Students – I am so proud of you. You read my book. You know all the rules. You have passed every test. Now you can play basketball like Michael Jordan!”

How much would you agree with that last statement? My guess is that most of you would very strongly disagree. Now think about why you feel this way. What is missing in the fabricated experience just described?

Quantum breakthrough could revolutionise computing

Computer scientists have been trying to make an effective quantum computer for more than 20 years. Firms such as Google, IBM and Microsoft have developed simple machines.

But, according to Prof. Winfried Hensinger, who led the research at Sussex University, the new development paves the way for systems that can solve complex real world problems that the best computers we have today are incapable of.

"Right now we have quantum computers with very simple microchips," he said. "What we have achieved here is the ability to realise extremely powerful quantum computers capable of solving some of the most important problems for industries and society."

Currently, computers solve problems in a simple linear way, one calculation at a time. In the quantum realm, particles can be in two places at the same time and researchers want to harness this property to develop computers that can do multiple calculations all at the same time.

Quantum particles can also be millions of miles apart and be strangely connected, mirroring each other's actions instantaneously. Again, that could also be used to develop much more powerful computers.

One stumbling block has been the need to transfer quantum information between chips quickly and reliably: the information degrades, and errors are introduced.

But Prof. Hensinger's team has made a breakthrough, published in the journal Nature Communications, which may have overcome that obstacle.

The team developed a system able to transport information from one chip to another with a reliability of 99.999993% at record speeds. That, say the researchers, shows that in principle chips could be slotted together to make a more powerful quantum computer.
