永夜前的最後一道光！白矮星與黑矮星的終極奧祕？ (The Last Light Before Eternal Darkness – White Dwarfs & Black Dwarfs)
- If the proton, one of the fundamental parts of atoms, has a limited lifespan, black dwarfs will slowly evaporate over many trillions of years.
儘管如此如果你太靠近，它的質量還是足以殺死你
- If the proton does not decay, black dwarfs will probably turn into spheres of pure iron via quantum tunneling over a timespan so obscenely gigantic that calling it "forever" is ok.

宇宙尺度 - 我們「微小」的宇宙數字解析 (上)！ (Scale of the universe - Our TINY UNIVERSE in NUMBERS (Part 1))
- Hydrogen Number 1 of the periodic table, with one electron orbiting one proton, hydrogen is the most abundant element in the universe and probably the first that ever existed. 4.
氫 氫是元素週期表中的 1 號元素，一個電子繞著一個質子運行，是宇宙中最豐富的元素，也可能是有史以來最早存在的元素。4.
- Number one of the periodic table, with one electron orbiting one proton, hydrogen is the most abundant element in the universe and probably the first that ever existed.
現在我們不這樣做的原因是第二種力--電磁力，它可以通過斥力和吸引力與任何帶電荷的原子和分子相互作用，共同將你和地板保持為一體。
反物質之謎！ (The Riddle of AntiMatter)
- So for every proton, there's an antiproton.
這些粒子對開始互相湮滅。
- So for every proton, there's an antiproton. For every electron, there's a positron. For

- There's external beam radiation, or EBRT, which involves techniques like intensity modulated radiation therapy, or IMRT, and proton therapy, which require advanced equipment and multidisciplinary teams.
有體外放射治療（EBRT），其中涉及強度調製放射治療（IMRT）和質子治療等技術，需要先進的設備和多學科團隊。
- proton therapy, which require advanced equipment and multidisciplinary teams.
它最常用於治療前列腺癌和宮頸癌，不過術中近距離放射治療也可用於治療其他一些類型的疾病。
