You've fired up the grill, set up the badminton   net, are those dark clouds on the horizon?

當你架起了烤肉架或是搞定了羽毛球網但往地平線方向看去,卻有一塊烏雲?

不用拿出你的手機 因為你的鼻子已經知道了

Our noses can detect up to a trillion different scents,   and many   of them are deeply tied to our memories and our emotions.

我們的鼻子可以偵測多達一萬億不同的氣味， 那些氣味都深深印記於我們的記憶中和情緒。

Like your grandma’s house, your first dog, or the smell of rain

像你阿嬤的房子，你的第一隻狗，或雨的味道

Storm winds carry an orchestra of separate smells, but the earthy odor   that precedes a storm can be traced to three chemical sources.

強風帶來交響樂般的氣味饗宴，在強風來之前有種獨特的氣味是來自三種不同的化學來源。

Before a thunderstorm, you’re probably smelling ozone, which interestingly gets its   name from the Greek word meaning “to smell”.

在暴雨之前你可能會聞到一股臭味 有趣的是那股臭氣是來自希臘字"聞"的意思

The electrical charge of lightning high up in approaching   storm clouds splits oxygen gas into separate atoms

帶電雲的閃電平繁 接觸氧氣時候產生不同的原子出來

That Ozone is swept ahead of the advancing storm by   windy downdrafts, and down to your nose level.

臭氧是由風靡推進風暴前多風的下沉氣流 並因下沉氣流而使在地面上的你可以聞到

As rain begins to fall, a new smell springs from the soil

開始降雨時 土壤就會散發出氣味

the pleasantly pungent perfume we call “petrichor”.

這種刺鼻的香水氣味 我們稱之為Petrichor

Petrichor gets half its name from the ethereal essence that flowed through the   veins of Greek gods and half from the stones of the Earth

Petrichor這個字 前半意思是地球上的石頭 ichor則是希臘神的意思

which actually kind of captures its science, and the   powerful feels I get when I smell it.

這是一種科學的印記跟強而有力衝擊的感受

When decomposed organic material is blown airborne from dry soil, it lands   on dirt or rocks, where it’s joined by minerals

當那些有機物質分解後從土壤散發出來 並混合了灰塵何時頭上的礦物質

and the whole mixture is cooked into this magical medley of molecules.

整個混合物熟成後轉換成神奇的分子

Falling raindrops then send those chemicals airborne right into your nostalgic nostrils.

伴隨著雨滴 這些你的鼻子將會聞到這些化學物質的味道

When there’s no rain around, those same chemicals remain in the soil, where they signal plants to   halt their roots from growing or prevent seeds from sprouting when there’s no water to drink.

當周遭停止下雨 這些化學物質將會才留在土壤中 因此提醒植物停止生長或種子發芽 因為會導致沒有水喝

Petrichor: it’s for the plant that’s tired of waiting ...to germinate.

Petrichor:是讓植物厭倦不斷的在等待與發芽間抉擇

Bacteria in the soil also contribute to petrichor   by releasing a chemical called geosmin,

在土壤裡面的細菌會助於Petrichor釋放一種名為土臭素的化學物質

that's the same compound that gives beets their earthy flavor.

這是一種化合物 會散發出甜菜的味道

Within there is other purposes for petrichor besides showering us with emotion.

Petrichor除了改變我們的情緒之外

It starts to attract camels to desert oases, who slurp up   and transport the soil bacteria across the sands.

也吸引駱駝前往綠洲喝水 並在路途上挾帶土壤裡的細菌到其他地方

Petrichor: that’s washed into rivers and lakes also seems   to signal fish that it’s time to spawn.

另一個目的是傳送訊息給河水裡面的魚群 下達產卵的訊號

Nothing like a rainstorm to spark a little romance, I guess.

我想沒有什麼東西能比暴風更浪漫了

So next time you smell a summer storm coming, take a minute to   think about what that rock over there is trying to tell you.

所以下一次當你聞到了夏天的暴風雨要來臨的時侯，花一分鐘去想想那岩石要告訴你什麼。

保持好奇心，之後試著聞聞看吧！

Why are sharks so scary? Bloodthirsty beasts just waiting out   there in the waves to beast on human flesh.

為什麼鯊魚這麼可怕？嗜血的野獸正在等待在要吃人肉。

only we get rid of these guys our vacations would be so much safer, nothing   to worry about while we're surfing and frolicking out there in the ocean.

只要我們能擺脫這些傢伙，我們的假期便會更加安全，並不用擔心我們在海中衝浪和嬉戲。
