This month

This month, more than a century after it was begun, a secret tunnel that runs deep beneath the Atlantic Ocean was finally completed. And an extraordinary optical device called a Telectroscope was installed at both ends - one in London, the other in New York. (more…)

Since I hadn’t involved myself in much gardening work over the winter

Since I hadn’t involved myself in much gardening work over the winter, the old backyard was beginning to look a little like the darkest depths of the Cambodian jungle. So last month, the old Briggs and Stratton-powered mower was pulled out of hibernation and commanded to perform as it had done on so many occasions before. (more…)

According to the Energy Saving Trust

According to the Energy Saving Trust, if everyone in the UK topped up their loft insulation to 270mm, 380m pounds would be saved each year in annual fuel bills. So in the interest of putting some of those millions into my bank account, I called in the guys from the Big Loft Insulation Company to sort mine out. (more…)

Researchers from University of California Riverside’s Department of Chemical and Environmental Engineering are studying ocean animals

Researchers from University of California Riverside’s Department of Chemical and Environmental Engineering are studying ocean animals with an eye on future human applications (see (Link) for the original story).

Research group leader Professor David Kisailus said: “My hope is that we can truly learn from these organisms how to design, optimise, and synthesise engineering materials that display properties that we as engineers can only dream of.” This sounds plausible and even rather seductive, fitting in as it does with a whole slew of contemporary ideas that elevate notions of what is ‘natural’, ‘organic’ etc.

This backdrop, rather than the particular notion of studying ocean animals, makes me reticent to take such projects at face value. The problem of elevating the ‘natural’ (and so much of ‘nature’, not least the idea of ‘nature’ itself, bears a distinct human stamp) in this manner is that one could envisage a future where human engineers have their potential curtailed by having to fit into some kind of pre-ordained ‘natural’ pattern.

And we are talking about fundamentally different processes here. For example, the red abalone, a marine snail, may be an excellent architect in constructing its shell. On the other hand, a human architect may be awful at his or her job but still has the advantage over the red abalone in being able to conceptualise a projected building in imaginary terms before construction begins.

So I’m actually more with Professor Kisailus when he talks of utilising nature “as a platform for our inspiration”. True, I am less inspired at the thought of the red abalone aiding in the construction of lightweight armour to help soldiers become more proficient in the pursuit of future wars, but then that’s just me. However, the idea of nature as a font of inspiration is much more appealing than the idea of nature as a source of design templates.

Dave Wilson is away on his holidays. He’ll be back at the forge next week.

The tools of the trade

A lot of cool electronic devices were invented at the US research centre known as Bell Labs. Perhaps one of the most important was the operational amplifier, or op-amp, which saw its first incarnation during the early years of World War Two. (more…)
