讓你死十億次，成為永生不朽！ (Let's Kill You a Billion Times to Make You Immortal)
- A radioactive atom decays, another world exists where it didn't.
你正在觀察電子，所以也有五個版本的你。
- A radioactive atom decays, another world exists where it didn't.
你正在觀察電子，所以也有五個版本的你。
人體解剖學與生理學 (Anatomy and Physiology)
- level of atom which comes together to form molecules, macromolecules, organelles, cells,
原子層次，共同形成分子、大分子、細胞器和細胞、
- We start at the level of an atom, which comes together to form molecules, macromolecules, organelles, cells, tissues, organs, organ systems.
立方體。這個呢？那是分層鱗狀的你的皮膚就是這樣 Yeah.你的皮膚就是這樣的
這就是為何碳是個「流浪漢」！Crash Course 生物學 #1 (That's Why Carbon Is A Tramp: Crash Course Biology #1 )
- When I say carbon is small, I mean that it's actually, you know, as an atom.
在視頻中。
- It's a relatively small atom.
我保證，你可以盡情地對我做這個，我完全不會介意。
雷射原理是什麼？（理論篇） (How Lasers Work (in theory))
- And what's more amazing is that if a solitary photon passes by an excited atom that could emit another photon, there's a good chance it will emit one because the two photons want be together - even before the second one exists.
更驚人的是,如果一個單獨的光子穿過一個可能會產生光子的激發態原子,這樣很有可能會使它真的產生光子,因為光子傾向於在一起,即使第二個光子還沒存在。
- And what's more amazing is that if a solitary photon passes by an excited atom that could emit another photon, there's a good chance it will emit one, because the two photons want to be together, even before the second one exists.
未來是否已經發生？ - 時間的悖論！ (Did The Future Already Happen? - The Paradox of Time)
- For example, if you have a radioactive atom, it could decay at any moment - in the next second or in the next million years.
根據量子物理學，量子粒子本質上是隨機的。
- For example, if you have a radioactive atom, it could decay at any moment, in the next second or in the next million years.
例如，如果你有一個放射性原子，它隨時可能衰變，可能在下一秒，也可能在下一百萬年。
史丹佛奈米製程中心：乾蝕刻－乾蝕刻原理 (第四部分之三) (Stanford Nanofabrication Facility: Dry Etching - Dry Etching Mechanisms (Part 3 of 4))
- Any time you have ions in the surface, they will cause some atom displacement.
只要表面有離子存在，就會引起原子位移。
- Anytime you have ions in the surface, uh, they will, uh, displace cause some, uh, uh, atom displacement.
是以，我們希望整個化學反應器的結構和表面化學成分每次都相同。
