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.
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 a sensor that can help break down those mechanics.
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.
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.

曾入主名人堂的泰德·威廉姆斯曾经评价打棒球是体育运动中最难的事情。
尽管威廉姆斯在职业生涯中很轻松就达成了344次的安打率，但他说的说法很有道理。
用一根圆棍子准确击打一个圆球可并不简单。
这同时也是非常有趣的应用物理学中一个典型的例子。

职业棒球运动员通过科学帮助提高自己价值数百万美元的击球，这并不是新鲜事。
而一些方法则将重点集中在击球的神经科学方面—棒球运动员在看到球投出后做出反应，这背后所蕴藏的是大脑的深层机制。
但关于更多挥棒信息，一家名为泽普实验室的体育科技公司制造的传感器可以帮助突破大脑传统的机制。
该传感器位于这家公司“智能球棒”的把手处，其中的2个加速器及一个3轴陀螺仪能够对球棒速度、手速、打击角度等其他因素进行测量。
而这款仅有8克重的传感器可以通过蓝牙将信息发送到智能手机的APP应用程序上。
而接收数据后，APP应用程序则会在屏幕上再次重塑挥棒的立体影像，这样球拍就能接收细节信息并做出必要调整。
泽普公司的这款传感器也可以安装在高尔夫球杆及网球拍上。
无需过多赘述，泰德·威廉姆斯曾经表示投手是最愚蠢的人。
或许有人可以发明出一颗智能棒球来助他们一臂之力。
这样就可以反驳泰德·威廉姆斯啦。
1.come up with 想出
例句:Several of the members have come up with suggestions of their own.
有几位成员提出了自己的建议。
2.turn to 转向
例句:Tonight it's my turn to cook.
今晚该我做饭了。
3.focus on 集中
例句:The talks will focus on economic development of the region.
会谈将着重讨论该地区的经济发展。
4.pick up 拿起
例句:He picked his cap up from the floor and stuck it back on his head.
他从地板上拾起帽子，重新戴在头上。
