【宇宙終極謎團：時間】物理學家Brian Greene 葛林深入淺出解析時間！你我都會思考的奧祕！ (【宇宙最大謎團 - 時間】Brian Greene 葛林 - 物理學家由淺到深解釋時間 | 早晚會思考的問題)
- The limit is the speed of light, because light travels 671 million miles per hour.
極限是光速，因為光的時速為 6.71 億英里。
- The limit is the speed of light, because light travels 671 million miles per hour.
地球是如何圍繞太陽旋轉的，我們又是如何圍繞自己運行的，這些都是有形的。
巨型雷射如何清除太空垃圾？ (How giant lasers could get rid of space trash)
- Just one fragment, even 1 centimeter in size, moving at an average speed of 7 kilometers per second, is powerful enough to knock out a satellite.
只要有一個碎片，哪怕只有 1 釐米大小，以平均每秒 7 公里的速度移動，其威力就足以擊毀一顆衛星。
- Just one fragment, even 1 centimeter in size, moving at an average speed of 7 kilometers per second, is powerful enough to knock out a satellite.
脈衝光可以在不發生物理接觸的情況下，向物體發射一束能量並施加作用力。
科學新觀點：阻斷外星文明聯繫的量子力學之謎（Is Quantum Mechanics Stopping Aliens From Contacting Us?）
- A fundamental problem with interstellar communication is the speed of light—the distances between stars are just so big and light takes so long to get there, you have to be really efficient with your communication.
一種可能的解釋是，我們忽略了量子力學。
- A fundamental problem with interstellar communication is the speed of light.
星際通信一個根本性的問題是光速。
萬一不幸發生爆炸事件，該如何逃生自救呢？ (How to Survive a Building Explosion)
- The explosion sends out a blast wave made of highly compressed air particles, moving faster than the speed of sound.
爆炸會釋放出由高度壓縮的空氣粒子組成的衝擊波，其運動速度快於音速。

2016年5款超驚豔的機器人！Atlas、Spot、Cheetah、Pepper、ASIMO 預示未來趨勢！ (5 Amazing Robots 2016 - The Shape of Things to Come - Atlas, Spot, Cheetah, Pepper, ASIMO)
- In experiments on a treadmill and also an indoor track, the Cheetah robot successfully cleared obstacles up to 18 inches tall—more than half of the actual robot's own height—whilst maintaining an average running speed of approximately 5 miles an hour.
它可以推算出物體的高度和距離
- whilst maintaining an average running speed of approximately 5 mph
同時保持平均每小時 5 英哩的奔跑速度
黑洞解釋--從誕生到死亡 (Black Holes Explained – From Birth to Death)
- Within a fraction of a second, the star implodes, moving at about a quarter of the speed of light, feeding even more mass into the core.
在若干分之一秒內，恆星產生自爆，以 1/4 光速移動， 持續餵給核心更多的質量。
- Within a fraction of a second, the star implodes, moving at about a quarter of the speed of light, feeding even more mass into the core.
宇宙中所有重元素都是在這特別的時刻被創造的，而後恆星死於這場超新星爆炸。
