The history of surfing

...sand and into the water. New materials and techniques for shaping the boards changed this, and nowadays boards are made with hand-shaped polyurethane blanks covered with fibreglass and resin. This made them lighter, but reshaping the boards enabled them to be smaller as well, and these new, smaller boards extended surfing’s reach from the Pacific right across the world....

Harry Marshall - Earth in Vision

...sands, to use a natural history metaphor, but there’s enough to celebrate, enough of the positive. River Monsters is a box-office success. Is it a conservation success? So, for the last ten years we’ve been making a series with Jeremy Wade called River Monsters and it’s been, surprisingly I think, Animal Planet’s most popular, most watched series. Jeremy is a...

Is a technological solution always the best? The politics of toilets

...cast challenges like ending poverty or unsanitary conditions as technical problems in need of inventions, rather than social problems in need of political action. The Bill and Melinda Gates Foundation’s support for the Nano Membrane Toilet is a good example of this. Rather than fund governments to build out their sewage systems or provide monetary assistance to employ...

Stuck in the middle of a pandemic: are international students migrants?

...Casting them out and telling them to go home, as the Australian prime minister did, denies the constitutive nature of study to Australian public life. It marks students as neither migrants nor Australian, and therefore removes access to the benefits being offered to those who are deemed to ‘belong’. Melbourne city council announced that they were setting up a hardship...

Plasma nitriding/carburising

...cast irons can be treated, but should have a carbon content below 0.4% (and preferably below 0.25%) to produce a tough core. Process sometimes produces an over-high carbon content in the case profile, therefore a repeated carburise-diffuse sequence is adopted, relative process times are shown below. This is also used for producing deep cases. The shorter carburising times...

Two kings, two very different coronations

...cast a sense of the ridiculous over the ostentatious event. Commentators were quick to emphasise the contrast between their new monarch and the ‘adored’ late George III, whose thrift and morality had made him a symbol of British values during the drawn-out conflict with Napoleon. The more turbulent aspects of George III’s 60-year reign– the war with the American...

Do whales commit suicide?

...casts doubt on this analysis, with genetic tests showing that animals stranded close to each other during mass events may not be related after all. Perhaps this isn’t always a family tragedy.
