暗物質探測跑得比摩爾定律還快，卻只看到一個事件

we would not be in a situation where an analysis chain simply popped an event out of magic because of an AI component. And that was what we stood behind.

我們不會處在這種情況下：分析鏈因為一個 AI 組件就憑空變出一個事件。而那就是我們要為之背書的東西。

So we just realized we'd utterly failed our students in terms of really telling them about how research works, which is most of the time.

於是我們意識到，我們徹底辜負了學生——沒有真正告訴他們研究是怎麼運作的，而研究大多數時候就是這樣。

if we fired a single dark matter particle, hypothetical dark matter particle, through lead, we could actually pile that lead all the way out to the closest star beyond the sun … and actually go about twice, more than twice that distance, so 10 light years. And even though this dark matter particle was traveling through lead, less than 50-50 chance it would have interacted at that point.

如果我們把一個暗物質粒子、一個假想的暗物質粒子射進鉛裡，我們可以把鉛一直堆到太陽之外最近的恆星……再堆出大約兩倍、兩倍多的距離，也就是 10 光年。而即便這個暗物質粒子一路穿過鉛，到那個位置它發生相互作用的概率也不到一半。

It's just saying that the drift time of the electron and the location of where the electron hits the surface and lights up like a Christmas tree, that's the projection bit.

它說的只是電子的漂移時間，以及電子打到液麵、像聖誕樹一樣亮起來的位置——這就是「投影」那部分。

the first rule of physics is not to fool yourself, and the second rule is you're the easiest person to fool.

物理學的第一條規則是不要欺騙自己，第二條規則是你自己是最容易被欺騙的人。

adjectives don't cut it you have to associate quantitative numbers with things

形容詞是不夠的，你必須把定量的數字和事物關聯起來。

Rick Gaitskell1:26:22

we do so many experiments that you have to get unlucky in terms of a background fluctuation, which is why we often talk about five sigma as being a necessary requirement if you're really going to say a signal is robust enough to claim direct discovery

我們做了這麼多實驗，總得有人在背景漲落上運氣不好，這就是為什麼我們常說，如果你真要說一個信號足夠穩健、可以宣稱直接發現，五西格瑪是必要條件。

If an experiment or particular technology wants to work, I call that a low Sisyphean Index.

如果一個實驗或某項技術自己想工作，我稱之為低西西弗斯指數。

數字與實體

術語

look-elsewhere effect多重比較效應

信號可能出現在很寬的能量範圍內，局部顯著性需按搜索範圍折算成全局顯著性。

Sisyphean Index西西弗斯指數

Rick 自造詞：技術自己想工作的程度，指數越低越容易推進。

MSSI多點散射單電離

高能伽馬在探測器內多次散射卻只產生一次電離，可能被誤判為暗物質事件。

TPC時間投影室

用電子漂移時間和液麵光位置反推相互作用三維位置的探測器。
