Bohr's atomic model 100 years old

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.

John Ellis brings the universe's secrets down to earth

John Ellis, now 66, is one of the foremost experts in the field of particle physics. Ellis has appeared on The Daily Show and in the pages of Vanity Fair and The New York Times, as CERN, its Large Hadron Collider and the elusive Higgs particle they may have helped discover became the stuff of sexy science.

Neutrinos go 'missing' on their journey from the Sun to earth.

Scientists have criticised an Italian government decree allowing a group of terminally ill patients to continue using an unproven stem cell treatment, saying such therapies may cause harm and risk exploiting desperate people.

The science fictions of Arthur C. Clarke will go electronic.

Scientists at Europe's CERN research centre said they may be able to definitively announce in March that they have discovered the elusive Higgs boson.

New particle is simplest version of Higgs boson

Scientists working at the Large Hadron Collider have found no evidence that the new particle discovered earlier this year is anything but the simplest - and most boring - variety of Higgs boson.

It is hard to follow a conversation with Maxim Kontsevich, as he peppers it with unfamiliar terms such as mirror symmetry and vector spaces.

For the average person, the Russian mathematician may well have hailed from another dimension - delving into the mysteries of the universe to determine through maths how unseen forces balance one another.

Corrections & clarifications

The caption to a photograph of scientist Peter Higgs accompanying the report, 'Behold the God particle', on page 13 of the Sunday Morning Post on July 8 stated, incorrectly, that he is a Nobel laureate.

Higgs helpers cement HK-CERN pact

Two Hong Kong students were part of the team that discovered the 'God particle', or Higgs boson, in Switzerland last week.

The European Organisation for Nuclear Research (CERN) was so impressed with their contributions that they signed an agreement with Chinese University yesterday to continue a student research programme.

'Now the hard work on Higgs boson begins'

Joyous celebration of the discovery of a new particle that looks like being the Higgs boson has been short-lived. Intense study of the properties of this elusive particle has already begun, according to two students from Chinese University working at CERN.

Behold the God particle

You've surely seen the big science news of the week: the Higgs boson, aka the God particle, has been discovered. Hooray! Huzzah!

At last, a European project triumphs

Amid all the doom and gloom about the possible break-up of the euro zone, another grand European project which has time and again been threatened with failure has delivered. Many of the world's finest physicists at Cern have, by using the Large Hadron Collider (LHC), found what is likely to be the Higgs boson, the long-sought particle needed to complete the standard model of physics.

Cosmic sleuths on the case

It's not every day you get to help determine a fundamental constant of nature and a new phenomenon in particle physics. But an international team of scientists believes they have done just that, at an underground site near Daya Bay's nuclear plants.

Daya Bay shines light on dark matter

An international team led by mainland scientists announced in Beijing yesterday that it had discovered a new form of elementary particle behaviour at Guangdong's Daya Bay nuclear power plant.
