科学美国人60秒:智能传感器或使你的球技更上一层楼

Hall of Famer  Ted   Williams   once   famously   commented   that   hitting   a   baseball   is   the   hardest  thing   to   do   in   sports .
Although   Williams — a  .344  career   hitter — made   it   look   easy ,  he   had   a   point .
Hitting   a   round   ball   with   a   round   bat   squarely   is   difficult .

It's also an excellent example of some very entertaining applied physics.

Hall of Famen. 名人堂

squarely  ['skwεəli]    adv. 直角地；诚实地；正好；干脆地；正当地

No   surprise   then   that   professional   baseball   players   are   turning   to   science   to   improve   their multimillion - dollar   strokes .
Some   approaches   focus   on   the   neuroscience   of   hitting    the   deep   internal   brain   mechanisms behind   seeing   the   pitch   and   reacting   to   it .

But for more info about the swing itself, a sports tech company called Zepp Labs makes asensor that can help break down those mechanics.

pitch  [pitʃ]    vi. 倾斜；投掷；搭帐篷；坠落 vt. 投；掷；定位于；用沥青涂；扎营；向前倾跌 n. 沥青；音高；程度；树脂；倾斜；投掷

swing:摇摆 挥球

The   sensor   sits   in   the   knob   of   the   company's   so - called  “ Smart   Bat ”  and   uses   two   accelerometers  and   a   three -a xis    gyroscope   to   measure   bat   speed ,  hand   speed ,  attack   angle   and   other   factors .
The   sensor ,  which   weighs   only   about   eight   grams ,  sends   this   info   to   a   smartphone   app   via  Bluetooth .

The app can then use this data to have an onscreen avatar reenact the swing, in the hope that the batter can pick up some details and make the necessary adjustments.

knob  [nɔb]    n. 把手；瘤；球形突出物 vi. 鼓起 vt. 使有球形突出

accelerometers      n. 加速计（accelerometer的复数）；加速器；感应器

gyroscope  ['dʒaiərəskəup]    n. 陀螺仪；回转仪

attack angle 攻角；[测] 迎角；[机] 冲角

  reenact  再现

batter  ['bætə]    n. 击球手；

Zepp's   sensors   can   also   be   fitted   to   golf   clubs   and   tennis   rackets .
Never   one   to   mince   words ,  Ted   Williams   also   once   said   that   pitchers   were  “ the   stupidest   people  alive .”
Hmm ,  maybe   somebody   could   come   up   with   a   smart   baseball   to   help   them .

Against any Ted Williamses out there, anyway.【这句并没有懂】

come up with    提出；想出；赶上
