The reason I'm showing you this is it that this is a gain, a common trade off in computer science.
我向你们说明这个,是因为是这个计算机科学中。
Well, if you're implementing a computer that needs to represent information now all you need is something like electricity which can be on or off, on or off.
好吧,如果你正用一个电脑,来表现表达传递信息的功能,你就需要,像电开关一样的物体。
Okay. Now take your hand on a chair or your notebook, your computer or whatever, and do syncopation off of that according to this pattern.
好的,现在用手拍椅子,或者笔记本,电脑,随便什么,来按照这个模式做切分音
This is a very important mission and so there is a computer program named Hal that helps run the ship and takes a lot of the burdens off of the part of the human astronauts who are on the ship.
这是一项非常重要的任务,因此,一个被命名为哈尔的计算机程序,被安排协助飞船的运行,减轻飞船上,人类宇航员的负担
But at the end of the day, and here's why we just went with binary and not decimal years ago, when you have one implement a computer with a physical device, it's actually really easy to represent the notion of on or off.
但是最终,之前我们采用二进制,而不是十进制,主要是因为当我们用一台实体机器运行计算机时,这实际上很容易用开或者关的概念来表示。
Is it streaming off of your computer?
用电脑播放碟片吗
If you're in this state, you will necessarily, given the laws of physics and the way the computer's programmed and built and so forth, these wires will turn on, turn off, these circuits will turn on, turn off, boom, suddenly you'll be in that state.
如果你站在这个角度,你必定会考虑,在物理定律和电脑编程原理,如何构造的等等确定的情况下,这些电线通或断,这些回路通或断,嘣,突然你就处在那个位置上
You're not going to start for the rest of your life if you ever need to solve a problem with a computer from scratch, odds are you're going to reach for some off the shelf packages or libraries or tools that other people wrote so that people like us don't have to reinvent the wheel again and again.
如果你想用Scratch来解决问题,却使用其他人写的程序,或者利用现成的资料或工具,这样以来,我们的确可以避免做重复性的工作,但却永远学不会编程。
