As part of its measures to deal with the hot conditions expected at the 2020 Tokyo Olympic and Paralympic Games, on Aug. 13 the Tokyo Metropolitan Government conducted an experiment to measure the effects on pavement surface temperature of spraying the road surface with water. Data from the experiments were released to the media.
The experiment was conducted from 4:00 a.m. to 10:00 a.m. along a 120 m section of sidewalk along Uchibori Street in the Imperial Palace's outer gardens in Chiyoda Ward. In the experiment, open-ended tubes used in agricultural work eres placed at the edge of the sidewalk to supply water. Surface temperature readings were taken every 30 minutes for three different experimental scenarios: spraying water beginning at 4:00 a.m.spraying water beginning at 7:00 a.m.not spraying any water
The experiment found that where water had been sprayed, the road surface temperature remained in the 27 to 29˚C range even when the air temperature exceeded 30˚C. Where no wa…
It's been 122 days since the 122nd Boston Marathon. Of what the two exceptional people who won that day accomplished, WilliamShakespeare summed it up better than any other commentator in his Sonnet 122:
Beyond all date, even to eternity; Or at the least, so long as brain and heart Have faculty by nature to subsist; Till each to razed oblivion yield his part Of thee, thy record never can be miss'd.
What else needs to be said? But the other thing that remains from that day is, of course, this:

In the 122 days since Boston this clip has been on my mind a lot. The commentary here by Larry Rawson and Al Trautwig was exceptionally bad, but it wasn't unique to them and highlighted many of the problems with marathon TV broadcasts and especially their hosts and commentators. I'm fortunate to live in Japan where the announcers for the countless marathon live TV broadcas…
Its skyline punctuated by skyscrapers demonstrating Indonesia's economic ascension. A lush plaza holding a famed tower, the symbol of the metropolis. When Jakarta hosts the Asian Games next week its marathon course will loop around the city's main streets, starting and finishing from the Games' main venue, Gelola Bungarno Stadium. In light of the heat and humidity of the races' summertime dates, Aug. 25 for men and 26 for women, the marathons will get off to early starts at 6:00 a.m. local time, 8:00 a.m. Japan time.
Leaving the stadium for the main streets, the Jakarta course turns to the north before turning back. Each of the two loops is about 20 km, both mostly flat and straight with the only hills coming in the gentle climbs onto and off the waterway bridges that dot the route. At a rotary about 5 km from the start, runners are greeted by a statue of a man and woman built in 1962 the last time Jakarta hosted the Asian Games. Running on amid the highrises, around …
