Quantum Mechanics

Bohr's atomic model 100 years old

Picture an atom, and you may imagine spherical electrons orbiting a nucleus packed with particles like neutrons. Only certain orbits - quantum levels - are possible. It's a simplistic model, yet provides insights into atoms and chemical properties, and this year marks 100 years since the model was first proposed by Danish physicist Niels Bohr.

A far-fetched idea that might compute

In the popular science fiction film The Matrix, reality as perceived by humans in the future is actually not real but a virtual, simulated world created by machines to subdue and control the human race. The film plays with the strange idea that we humans may have become an integral part of a purely fictional computed reality and that we exist inside a computer simulation.

In Search of the Multiverse

In Search of the Multiverse by John Gribbin Wiley HK$200

How many versions of you are there - one or millions? Some physicists believe that an infinite number of universes exist parallel to the one we live in.

New theory on how it all started

While we were rolling out the red carpet, Stephen Hawking apparently didn't see fit to share with us his latest and even more intriguing theory about how it all started. Apparently, Hawking and his colleague, Thomas Hertog, of the European Laboratory for Particle Physics, have a startling new proposal about how the universe was created.

A quantum leap in the transfer of money

Is a 100 per cent foolproof security system possible? The answer seems to be yes, after a group of clever quantum cryptographers working with the Bank of Austria transferred 3,000 euros (HK$28,000) last week using what may be the most unbreakable channel in the history of humankind.
