《那些古怪又讓人憂心的問題》第78期:致命中微子(3)

GRB 080319B was the most violent event everobserved-especially for the people who were floating right next to it withsurfboards.

GRB#0103898是觀測到的最爲劇烈的超新星——尤其是對就飄在它旁邊的人來說

The idea of neutrino radiation damagereinforces just how big supernovae are. If you.observed a supernova from 1 AUaway-and you somehow avoided being incinerated, vaporized, and converted tosome type of exotic plasma-even the flood of ghostly neutrinos would be denseenough to kill you.

中微子輻射傷害的計算進一步加深了你對超新星究竟有多大的理解。如果你在一個天文單位外觀察超新星——並且通過某種手段你沒有燒起來，也沒有氣化，或是變成某種奇異等離子體——那麼單單是洶涌而來的幽靈般的中微子就足夠置你於死地。

If it's going fast enough, a feather canabsolutely knock you over.

如果速度夠快的話，一根羽毛也絕對能把你撞倒。

1 Less often if you're a child, since youhave fewer atoms to be hit. Statistically, your first neutrino interactionprobably happens somewhere around age ten.

1．如果你是個孩子的話頻率可能更低一些，因爲你身體裏的原子也少嘛。從統計學角度來看，中微子第一次撞擊到我身體裏的某個原子應該是在我10歲左右的時候。

2 Which would still be less than 1 percentof the ants in the world.

2．只佔全世界螞蟻的1％還不到。

3 If you want to be mean to first-year calculusstudents, you can ask them to take the derivative of ln(x)e dx. It looks likeit should be “1”or something, but it's not.

3．如果你想爲難剛學微積分的學生的話，問他們ln(x)e的導數是什麼。看上去應該是1或者其他什麼簡單的表達式，但其實不是。

4 “Supernovas”is also fine. “Supernovii”isdiscouraged.

4．拼成supernovas還說得過去，拼成supernovii就算了吧。

5 3.262 light-years, or a little less thanthe distance from here to Alpha Centauri.

5．約3.262光年，或者說比地球到半人馬座α的距離略短一些。

Q. A toxin blocks the ability of thenephron tubule reabsorption but does not affect filtration. What are thepossible short-term effects of this toxin?

Q．如果有一種毒藥能夠阻斷腎小管的再吸收功能，但不影響過濾功能，那麼服用這種毒藥在短期內會產生什麼影響？

Q. If a Venus fly trap could eat a person,about how long would it take for the human to be fully de-juiced and absorbed?

Q．如果捕蠅草可以吃人，那麼一個人大約需要多久纔會被捕蠅草完全液化並吸收呢？
