Describing the International Space Station:
"The largest single ISS module—the centerpiece of Japan’s contribution to the station—is scheduled to be launched into space in October 2008. The pressurized volume inside this metal-walled module will be about 150 cubic meters, or about half the size of a squash court."
Describing air quality tests:
"‘When using traditional methods, measurement of diesel particle levels requires a test cell the size of a squash court, crammed with over a million dollars worth of equipment, operated by two or three highly skilled staff, but only producing vehicle test results every two to three hours.’"
On remote controls:
"The world’s largest TV remote controller is owned by Japanese businessman Henri Osaka. Weighing in at over 55lb, the unit is roughly half the size of a squash court. Ironically enough, the TV it controls is just a regular 30” set!"
Is it politics, or is it a scientifically-allocated quantity of space?
"The World Bank and the IMF have disagreed with the city- state's ban on outdoor assemblies and its objection to 27 of the more than 700 civil society representatives accredited by the event organizers. A 538-square-foot area, about the size of a squash court, has been set aside at a corner of the downtown convention center venue for the civil society groups to protest."
On a cutting-edge way to clear mines:
""We train them to detect concentrations of explosives lower than those they experience in a real minefield. That way we can guarantee a rat will never walk over a mine without indicating its presence," Mr Weetjens said. On their first assignment in Mozambique the rats swept an area the size of a squash court in 30 minutes. As yet no mine has been missed."
I thought I had a conclusive case, but it turns out that tennis courts are also used as a scientific measurement. Satellites and lumps of gold are both measured in terms of tennis courts. Alveoli are special, as they can be measured in both tennis courts AND in badminton courts. Only oceanographers and engineers use volleyball courts, however.
And as for the future of scientific measurement, that lies in handball courts. (PDF)
