Mathematics is not a deductive science—that's a cliché. When you try to prove a theorem, you don't just list the hypotheses and then start to reason. What you do is trial and error, experimentation, guesswork.
數(shù)學(xué)不是一門演繹科學(xué)——那是陳詞濫調(diào)。當(dāng)你試圖證明一個(gè)定理時(shí),你不僅僅是列出假設(shè)然后開始推理。你所做的是反復(fù)試驗(yàn)、實(shí)驗(yàn)和猜測。
化學(xué)工業(yè)是現(xiàn)代文明的支柱,我們必須以應(yīng)有的尊重和責(zé)任對待它。
The most sustainable fashion is the piece you already own.
我對我生命中的一切心存感激。
The materials we choose today become the legacy we leave tomorrow.
聰明人:在烏云顯現(xiàn)出來之前就看到暴風(fēng)雨即將來臨的人。
