In this Catalyst article, Mike Follows describes the surprising range of thermometers available to scientists today.

Many physical properties of materials depend on temperature. Thermometers are vital for measuring body temperature. The body's biochemical reactions work best at 37°C and the body is in...

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. The human brain may be the most complex structure in the universe.

The brain is so powerful that it is attempting to...

This Catalyst article looks at thorium - a heavy element, similar to uranium. Some people think that it could be the nuclear fuel of the future, as it can be used as the fuel in a fission reactor - and it appears to be much safer than uranium.

A Catalyst article about neutrinos. Neutrinos are fundamental particles. They are tiny, a neutrino has a mass about one-millionth of the mass of an electron, and they have no electric charge. This article looks at the detection of these elusive particles which requires the use a giant detector. The one described is...

This article, from the Association of Teachers of Mathematics (ATM) publication ‘Mathematics Teaching’, and is taken from MT227. Ian Thompson reviews the evidence of effective practice in the teaching of early arithmetic found by Ofsted and published in the document...

Royal Navy Search and Rescue helicopters provide cover to large sections of the UK coastline, offering support to coastguard services 365 days a year.

These materials from Defence Dynamics encourage the use of problem solving skills and knowledge of trigonometry to directly assist the Royal Navy in a series...

This Catalyst article looks at peatlands which usually conjures up images of bleak, boggy hillsides across Northern Europe, Russia and the USA. But peatlands are also found in the tropics. These currently act as a significant store of carbon, yet these valuable ecosystems are under threat; their disappearance could...

In this Catalyst article an experiment is described in which the formation of clouds can be replicated. The experiment requires nothing more than a plastic bottle, warm water, matches and a small thermometer.
