I'd only have 16 possible two base sequences, that's not enough to specify over 20 amino acids.
如果两个碱基一组那一共只有十六种组合,不够和二十种氨基酸来一一对应
The fan base here is like a real... Let's see...
这里的球迷真的是……我想想……
Having done that, it goes back up and picks the second sub-list, which came from there. It's a down to base case, merges it.
就是从那里得来的,完成这些后,回到上一步。
In this case, to optimize for the best of the whole community and the whole user base and over the long term and that's important too, your long over short term.
在这个前提下,去寻求整个社会,以及所有用户的长远利益的最大化,这十分重要,我们寻求长期利益,而非眼前利益。
How many combinations of codons are there if there's three bases and four possibilities at each base?
那密码子的组合方式到底有几种呢,三个位点,每个位点四种选择
This really provides the central rhetorical base for Milton's Lycidas.
这为弥尔顿的《利西达斯》提供了行文基调。
What's happened actually if we base it in the last 25 years since the early '80s We've just had two recessions and they've been very mild by historical standards and...two--now three long expansions in between.
实际上是什么情况呢,80年代初期以来,这25年当中,我们只经历过两次经济衰退,而且在历史上算是相对轻微的,其间则是两,三次长时间的经济增长。
And there's a real spatial sense here, that it's being generated at the base of the world, and it goes up and it transforms these mountains into papier-mache.
这里有一种真实的空间感,是从世界的基本中产生的,这种空间感上升并转化成这些纸型的山。
So that's why that base case rule was so important.
这就是为什么基本条件是如此重要。
And that then let's me get to, basically, base this code. Having done that, height I simply call base with get float, I call height with get float, and do the rest of the work.
现在让我们看看这段代码,其实已经写好了,我简单的调用下,用来得到一个浮点数,再调用下,来得到另外一个浮点数,然后做剩下的工作就可以了。
We call that a base case. It's basically the simplest possible solution to the problem.
我们说这是一个基础案例,这是这个问题最简单的解决方案。
The second question I want to ask is what's the base case? When do I get down to a problem that's small enough that it's basically trivial to solve? Here it was lists of size one. I could have stopped at lists of size two right. That's an easy comparison.
第二个问题是什么是基础条件?,我要将问题分解到何时才使得问题,小到可以解决的基本问题?,这里是当列表的长度为1有时候,我也可以在长度为2的时候停止分解,那是一个非常简单的对比。
Even if we locate a source of some kind of genuine strength, authoritative strength, it's still usually possible, as it is for Satan, to argue that that power is really at base just the concealed product of custom or what we would think of as cultural construction.
有时即使我们找到了一种真实的,权威的力量,还是有可能像撒旦所辩解的那样,这种力量其实只是,约定俗成的规矩教条的隐秘产物,或者如我们所想来自文化建构。
That's because every three base pairs describes an amino acid in a protein.
那是因为每三个碱基对,对应一个蛋白质中的一个氨基酸
And again, if I just run this, just to show that it's going to do the right thing, it says enter base, I'm obnoxious, it says oops, wasn't a float, so we'll be nice about it and I enter a height, and it prints out what I expected. I just concatenated those strings together, by the way, at the end.
我再来运行下看是不是做对了,提示输入底,噢,它提示说不是浮点数,我很高兴,然后我输入一个,浮点数作为高度显示结果和我预期的相同,顺便说一句,我只是在最后把这些字符串连接起来了。
Yeah. You're jumping slightly ahead of me, but basically, I'm done when this is equal to 1 right? Because I get down to the base case, so I'm done when b u is over 2 to the k is equal to 1, and you're absolutely right, that's when k is log base 2 of b.
因为这就是最基本的情况了,因此当b/2的k次方等于1的时候就停止了1,你说的太对了,就是k等于b的以2为底的对数的时候,你们都坐的挺靠后的啊,我不知道是不是我讲的不太明白?
