  1. How can a harder rubber be slower than a soft one?

    Please stick to the rules. Avoid staying the obvious in physics terms but try to obfuscate your explanation with technical jargon. :p

    Actually, the risk of athletes/coaches/staff getting sick is pretty low since they always keep the training sites off-limits to the public in the Olympic year(closed training is in itself a form of quarantine). The problem is getting them from China to other countries to compete before the...

    After a quick look, it appears postponement has never happened. The Games in 1916, 1940 and 1944 were cancelled due to WWI and WWII. They tried to move 1940 from Japan to Finland 2 months ahead but it didn't work out. So if it does get postponed, the odds are against China.

    Fresh off the boat. Here, to get you up to speed. Be sure check out the chart for Xtend series, which answers the OP's question.

    The problem now is the moment they land in China, they're pretty much grounded as countries worldwide deny entry for flights from China. So it's likely they'll have to stay overseas for next half year.

    The analogy I think of is motor unit recruitment, where muscle fibers are activated in order of size from smallest to largest depending upon the intensity, known as the size principle. As the force output increases, you start losing fine motor control as larger motor units take over, making it...

    A netizen named 桂花田(sweet olive field) from Taiwan did a similar experiment for glued/unglued Sriver series, Bryce series, Plasma series and many others over a decade ago and came to a similar conclusion.

    All right, time to get back on track. How about a he-did-the-math answer? A student named 佐藤 秀祐(SATO Shuusuke?) of Keio University did a paper on this topic in 2014. Basically, it involves dropping a ball onto the racket with soft and hard rubbers from different heights and the rebounds are...

    One big difference from SARS and thus challenge with the novel coronavirus is that the incubation period is longer(as long as 14 days vs 10 days) and there are many cases where the infected do not exhibit ANY symptoms, essentially acting as "transparent mobile carriers". That makes it much...

    Given its 85% similarity to SARS, it will likely die out once summer comes as the virus has trouble surviving above a certain temperature.

    Ito and Mizutani are a special case. They're from the same hometown and have known each other for so long. Ito calls him Jun, completely disregarding honorifics. It shows how close they are.

    WMY is a non-factor now that ZYL, who is out of the race, is in the WTTC lineup. Everything that matters on the women's side is Ito...

  19. German Open 2020

    This is the best tournament for Ishikawa/Hirano thus far. Ishikawa kept up with Hirano for the most part. She still comes up short when it gets tight, especially on her serve in G1 and G4.
