| 1. 有關臺階的有趣事實 |
|
| Sheldon: You want to hear an interesting thing about stairs? If the height of a single step is off by as little as two millimeters, most people will trip. |
謝爾頓：關于樓梯有件蠻好玩的事，你想聽聽嗎？假如單個臺階的高度比標準高度低2毫米，大多數人就會絆倒。 |
| It's true. I did a series of experiments when I was twelve; my father broke his clavicle. |
是真的。我12歲那年曾經做過一系列實驗，我父親因此摔斷了鎖骨。 |
| 2. 科幻電影事實上并不科學 |
|
| Sheldon: Let's assume that they can (fly). Lois Lane is falling, accelerating at an initial rate of 32 feet per second per second. Superman swoops down to save her by reaching out two arms of steel. |
謝爾頓：讓我們假設人類可以（飛）。路易絲?萊恩從高空墜落，初始加速度為32英尺/秒的平方，途中不斷加速。超人俯沖下來，用鋼鐵般的雙臂接住她。 |
| Miss Lane, who is now traveling at approximately 120 miles an hour, hits them and is immediately slice into three equal pieces. |
萊恩小姐此時的運動速度約為120英里/時，猛撞上超人的手臂后，身體立即被切為三等份。 |
| Frankly, if he really loved her, he'd let her hit the pavement. It'd be a more merciful death. |
坦白講，如果他真的愛她，就應該讓她直接摔在馬路上。那會是種更仁慈的死法。 |
| 3. 維生素藥劑 = 昂貴的尿液原料 |
|
| Sheldon: Well, there's some value to taking a multivitamin, but the human body can only absorb so much. What you're buying here are the ingredients for very expensive urine. |
謝爾頓：服用多合維他命有一定的好處，但人體所能吸收的量是有限的。你所購買的維生素藥劑會變成十分昂貴的尿液原料。 |
| 4. 時間旅行的悖論 |
|
| Sheldon: If you would've prevented yourself from buying it (the time machine) in the past, you would not have it available in the present to travel back and stop yourself from buying it. Ergo you will still have it. This is the classic rookie time travel mistake. |
謝爾頓：如果你用時間機器回到過去，阻止了自己購買這臺機器，那么在當前的時間點，你就沒有一臺時間機器能夠送你回到過去阻止自己購買這臺機器了。因此你還是會擁有它。這是典型的新手在時間旅行中會犯的錯誤。 |
| Same paradox. If you would've travel back in time and, say, knock me unconscious, you would not then have a conversation that irritated you, motivating you to go back and knock me unconscious. |
同理可證。如果你回到過去并且……比方說把我打暈；那么現在，你就不必和我進行這段令你心煩意亂的談話，但同時也就沒有了動機要回到過去把我打暈。 |
| 5. 發硬的面包所蘊含的科學道理 |
|
| Sheldon: You shouldn't keep your bread in the refrigerator. Staleness is caused by crystallization of the starch molecules, which occurs faster at cool temperatures. |
謝爾頓：你不應該把面包放進冰箱里。面包變硬是由淀粉分子間的結晶作用引起的，在低溫條件下，這一過程會加速。 |
