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 [‘skwε?li] 
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 theirmultimillion-dollar strokes.
Some approaches focus on the neuroscience of hitting the deep internal brain mechanismsbehind 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 [pit?] 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-axis 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 [n?b] 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 [‘d?ai?r?sk?up] n.
陀螺仪；回转仪
attack angle 攻角；[测]
迎角；[机] 冲角
reenact 再现
batter [‘b?t?] 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
