FINA, the governing body of swimming, has banned the full-coverage, low-drag swimsuits that are credited with aiding swimmers in breaking nearly all the world swimming records in the last year or so. I discussed drag reduction and its application to swimming in the lead up to the Beijing 2008 Olympics, where the Speedo LZR Racer swimsuit was the garment of choice for all would-be champions. In Beijing all but a couple of the existing Olympic records survived the LZR clad swimmer onslaught. Records were not only broken - they were smashed by huge margins instead of following a relatively steady historical progression.

The London Science Museum houses some historic exhibits as I found out on my recent visit. I've already posted articles on computing and rockets. Next up I'll cover a series of exhibits that related to the world's first Vertical Takeoff and Landing (VTOL) fixed-wing jet fighter - the Harrier 'jump jet.'

While on a recent visit to London I spent an enjoyable afternoon at the Science Museum. What I found was more sustenance for my computing-fluids obsession. In fact I came across enough fascinating exhibits to fill several blog posts. I'll kick off with a computing-themed post, first covering computing prehistory starting with the Babbage Difference Engines and the Phillips Hydraulic Computer, and moving on to the dawn of supercomputing with the Cray-1.
The ongoing Formula 1 (F1) diffuser controversy has raised the awareness in the general public (especially in F1-mad countries, such as the UK) of a key aerodynamic device used in many forms of motor racing. And if one diffuser is good then two must be better, right? So goes the latest thinking in F1.

Aerodynamic considerations in golf ball design are nothing new, but the other golfing implement, the club, has resisted aerodynamic optimization until now. A new generation of golf drivers is now sporting streamlined, aerodynamic profiles in order to improve driving distances due to reduced club-head drag.

You'd think that siting and constructing an offshore wind farm would be all about engineering and financial challenges, but you'd be wrong, at least in the case of the proposed Cape Wind wind farm in the waters off Cape Cod, Massachusetts. Cape Wind is a US$900 million project that aims to construct and run 130 horizontal-axis wind turbines to generate 468 (at peak) megawatts on Horseshoe Shoal in Nantucket Sound.
