Risk: most people have no grasp of very large or very small numbers, let alone ratios. How can we decide what risky activities to prohibit, what to regulate, and what to permit? Are business investors, racegoers and lottery punters playing the same game? This article offers a simple, intuitive index for the discussion and communication of uncertainty.
How can we reduce anthropogenic CO2 emissions quickly without destabilising the world economy or sacrificing Western society? Is carbon dioxide really a significant greenhouse gas? Here is a simple calculation and a proposed experiment to answer both questions.
In these articles I hope to promote a better understanding of autism and discuss some of the theories as to its cause.

Geodesics are often explained as “straight lines in a curved space” or sometimes “straightest possible lines in a curved space”, but what exactly is that supposed to mean?
This article considers the implementation and consequences of a radical, rational policy that demands neither suffering nor miracles (and can therefore be considered truly scientific) to produce an indefinitely sustainable quality of life rather better than currently enjoyed in the West, for everyone.
Toxins, pathogens, and bio-researchers are popular targets for fictional terror plots, but researchers take extreme measures to keep us safe.
Changes in Pacific Ocean sea surface temperature lead the trajectory of global surface temperatures in the last century - rising to the mid 1940's, falling to the late 1970's and increasing thereafter to the late 1990's. Physical mechanisms involving a transfer of energy and moisture between the atmosphere and oceans are identified to explain the influence of sea surface temperature on surface temperature at decadal timescales. The sea surface temperature state changes are abrupt as the system behaves like a complex and dynamic system in the terms of chaos theory
Midnight Sun: A natural phenomenon occurring in the summer months north of the Arctic Circle and south of the Antarctic Circle where the sun never fully sets and remains visible 24 hours a day. This short time lapse film was shot during the Icelandic Midnight Sun in June of 2011.
An account of just some of the technological advances pioneered by women in the recent past, inspired by the author's researches in the London Patent Office.

Today we take accurate maps of our country for granted, but how were the first maps made without the benefit of satellite imagery or GPS? This is the story of how the Ordnance Survey came to be, and how the First Series of One inch to the mile maps were made.
Curiosity is the latest rover to be launched towards the red planet by NASA, on 26th November 2011. Its mission is to investigate Gale Crater for signs that the region has ever had conditions favourable to life. Observations from orbit have already shown that Gale Crater contains exposures of clay minerals, which must have formed under wet conditions.
Gale Crater on Mars has been selected by NASA/JPL as the landing site for the Mars Science Laboratory, due to land on Mars in August 2012. This NASA video describes the landing site, the terrain the rover will traverse and the science objectives for the mission.

Silphium - was it a case of anthropogenic extinction, and why? Part V - cultivation, harvesting and storage
The extinct umbellifer-type herb silphium, once highly valued, is probably the first documented case of anthropogenic extinction due to over-exploitation and habitat destruction. Why was it so highly esteemed?
You'd not know it from TV news, but there's a whole fleet of spacecraft currently exploring our solar system...
I have always enjoyed programmes on the television which inform you of the latest discoveries in science but until relatively recently it was never more than a healthy curiosity that is common to most people.
