【明報專訊】今屆世界盃採用全新設計的足球Al Rihla，內藏的高靈敏度感應器為多個問題球如Ｃ朗的「上帝之髮」入球、日本翼鋒三笘薰底線助攻未有出界等，提供有力助證。雖然市面上買到的比賽版足球（$1199）未有這塊感應器，但與普通版（$259）相比，售價仍貴3倍有多，踢起來真的有什麼不同嗎？香港科技大學太古航天工程學教授兼空氣動力學和聲學實驗中心主任張欣及其團隊，將兩個足球放入低速風洞大比併，看看到底有什麼分別？ 在談足球設計之前，張欣先解釋影響足球飛行軌迹的一大因素——空氣動力學（aerodynamics），即物體在空氣中運動時所產生的各種阻力、側向力等。「雖然足球的射傳準確度與運動員的技術有最大關係，但當足球離腳後，影響它飛行…

Windsurfers often pump their sails back and forth to gain speed, but it can also cause slowing if done incorrectly. The complicated physics of the action was tackled by our group. Recently, the research group examined the propulsive dynamics of sail pumping on sailboards and established two quantities that measure the…
