  • Hungry for some pizza? We all like a good pizza pie to chow down on, but it turns out

    想來點比薩嗎?我們都愛大口吃美味的比薩

  • there’s a simple scientific solution to maximize your pizza experience!

    但你知道這裡有個簡單的方程式能讓你吃到更多的比薩嗎!

  • It all comes down to the the area of a circle - that equation you may have heard when you

    其實就是跟這個圓形食物的面積有關 - 在你們小時候應該都有學過

  • were young where the area = pi-r-squared (r being the radius). If we plug in some numbers

    一個圓的面積是 pi 乘上 r 的平方(r 是半徑)。假如我們代入數字

  • you may notice something interesting. For example, since we measure pizza in inches

    那麼有趣的事情就發生了。我們來舉個例子

  • in North America, the area of an 8” pizza is roughly 50 square inches. We simply take

    在北美,比薩是用英吋為單位,所以一片 8 英吋的比薩的面積差不多是 50 平方英吋

  • the radius of the pizza which is half of the diameter (so 4” in this case), put it in

    簡單來說就是用半徑,也就是直徑的一半(此例是 4 英吋)來計算,代入公式,就完成了

  • the equation and voila. But, if we do the same thing for a 16” pizza, which has a

    但如果我們再來算一下 16 英吋的比薩

  • diameter that is two times bigger, we find that even though your intuition may say it’s

    它的直徑是兩倍大,我知道你們直覺上會認為它面積應該也是兩倍大

  • twice as big, it actually has an area of over 200 square inches - which is 4 times MORE

    事實上,它的面積超過 200 平方英吋 - 足足是四倍的大小

  • pizza. This is because the area of a circle increases with the square of the radius. And

    這是因為圓面積是隨著半徑大小的兩次方而增長的

  • yet, most of the time the difference in price between an 8” pizza and a 16” pizza is

    然後,一般來說 8 吋比薩跟 16 吋比薩的價差根本

  • not even two times more expensive, let alone 4 times more expensive!

    不會差到兩倍價,更別說能賣到四倍的價格

  • In fact, NPR did a survey of over 74,000 pizza prices across America, and created an interactive

    事實上,NPR 對全美銷售的七萬四千多片比薩做了項調查

  • graph to show exactly how the price of pizza changes with size, and how much more pizza

    他們繪製了一個價格與大小對應的圖表,從中還可以知道當你點了份大比薩

  • you get when you order a large. For example, an 20-inch pizza has more area than two 14-inch

    到底你拿到比薩的份量多了多少。例如,一個 2 0吋的比薩比兩個 14 吋的比薩加起來

  • pizzas, or six 8 inch pizzas, yet it’s almost $9 cheaper on average than getting two 14

    或是比六個 8 吋的比薩加起來還要大,然而你點了一個 20 吋比薩會比你點兩個 14 吋比薩省了接近 9 美元

  • inch pizzas, and over $30 cheaper on average than getting six 8 inch pizzas.

    而平均來說,你點一個 14 吋比薩比上點了六個 8 吋比薩省超過 30 美元

  • And this is the pizza equation: the bigger the diameter of the pizza, the more bang for your buck!

    這裡有個比薩公式: 直徑越大的比薩越是物美價廉!

  • But why is pizza so tasty in the first place? We actually break down the science behind

    但為什麼比薩這麼美味呢?我們也有在 AsapTHOUGHT 頻道內探討
