So there is no real correct answer to this quiz if
この小テストに本当の正解はありません
you really don't like money, I guess you could prefer not
あなたがお金を本当に好きでない場合の答えは “お金を貰うことが好きではない”ですね
to be paid at all. The closest thing to a correct
正解に最も近いのは“時と場合による”です
answer is that it depends, and it depends on how you interpret the meaning of biweekly. We could look that up in
あなたが隔週の意味をどう解釈しているかで決まります
the dictionary to decide how we should interpret it, and if
どのように解釈すべきか確かめるために 辞書で調べることができます
we look up biweekly in the dictionary, what we see is
辞書で隔週を調べると隔週の定義を確認できます
the definition of biweekly, which is right here. It says happening every two weeks is the first definition. The
辞書によれば1つ目の定義には 2週ごとに起きることと書かれています
second definition is happening twice a week. If you
2つ目は1週間に2回起きることと定義されています
have the first definition, you'd rather be paid
あなたがお金が好きだと仮定して もし1つ目の定義で考えたら
weekly, assuming you'd like more money. If you have
1週間に1度支払われる方がよいでしょう
the second definition, you'd rather be paid biweekly.
もし2つ目の定義を採用するなら 隔週で支払われる方がよくなります
Maybe that's the problem with paper dictionaries, that they're not very precise, because they're old things. Let's look
おそらく紙の辞書に問題があるのでしょう 古いものですからあまり正確ではないのです
up a more modern dictionary, let's see what Wiktionary
より近代的な辞書を見てみます
has to say about this. So, here's the Wiktionary entry for
Wiktionaryではどのように定義されているのか 確認しましょう このWiktionaryに隔週と入力します
biweekly, and if we scroll down, we can see that it has two
そしてスクロールダウンすると 2つの意味があることを確認できます
meanings. Occurring once every two weeks, occurring twice a week,
2週間ごとに1度起きることと1週間に2度起きること
this is chiefly in the UK the American dictionary didn't seem to think that. It seemed to
まずイギリスですからアメリカの辞書が 違うことを定義しているとは思いません
think both definitions occurred in both countries. So,
両国で2つ定義が採用されていると考えます
this is a pretty big problem. If we wrote
ですからこれはとても大きな問題です
a computer program and the program was doing our payroll
もしコンピュータプログラムを書いていて プログラムが給料の支払いを行っており
and had to decide what it meant to pay someone biweekly,
“隔週で支払う”の意味を決定しなければいけない場合
we want to make sure it understood that the same way the programmer did. So that's one important reason why we need to invent new languages like Python to program computers,
プログラムがプログラマと同様に理解していることを 確実にしなければなりません すでに理解している自然言語を使用するのではなく コンピュータをプログラムするために
rather than using natural languages that we already understand. And that's
Pythonのような新たな言語を生み出す必要があるのは この重大な理由からです
because we don't really understand languages like English or Mandarin, that
人によって異なる解釈をしてしまうものが たくさんあります
there's lots of things that different people will understand different ways.
英語や中国語のような言語を 我々がよく理解できていないことも理由です
And this happens at the granularity of words like biweekly.
そして隔週のような言葉の粒度でこれが起きます
It also happens in complete sentences where there are many different
解釈の仕方がたくさんある 完全な文章でもこれが起きます
ways to interpret the same phrase. Another reason we don't use natural languages for programming is that natural languages are actually very
プログラミングに自然言語を使用しない他の理由は 自然言語がとても冗長だということです
verbose. To write a program, we need to describe exactly what the computer should do in very precise sequence of steps.
プログラムを書くためには正確な一連のステップで コンピュータが行うことを記述する必要があります
If we had to describe all those details using a natural
自然言語を使用して 詳細をすべて記述しなければならない場合
language, that would require a huge amount of text. So we'll
膨大な量のテキストが必要になります
see soon that with a programming language like Python,
今後Pythonのようなプログラミング言語を使えば
we only need a few lines of code to describe a complicated thing and describe it in a very precise, step by step way. So I want
複雑な事項をとても正確に少しずつ記述することが 数行のコードで済むことが分かります
you to think about as we write programs in this class, how much more detail you need to
ですからこのコースでプログラムを書いた場合 英語でどれくらい詳細に記述する必要があるか
actually describe in English, precisely how to do what we're describing with a few lines of Python code.
また数行のPythonコードを使用して記述する 正確な方法を考えてみてください
