It didn't come because you put some incredibly smart person in charge.

Over millions of years, variation and selection, variation and selection trial and error, trial and error.

It's still being tested.

Well Tim, it's kind of obvious.

So, it was back to the drawing board for us.

And it takes a lot of trial and error.

Trial and error is essential to progress.

(Applause)

You just need to say that right.

Don't feel that there should be a way that you can just always power through these problems.

Now I'm still eager to reach an agreement based on the principles of my bipartisan debt commission. No party has a monopoly on wisdom.

It's really helpful. This is my first time teaching a class.

But the art form is quite different than it used to be.

And we're still trying to keep with the real character.

And it has been for 50 years an experiment.

And then I'm going to show you it's actually a lot more complicated.

I sometimes wonder.

Our motto is, 'Fail early and fail often.'

And I'm going to show you a bunch of dead ends, basically.

These are the kinds of lessons as awkward as it was to be a pretty goofy teenager, much worse to be a frustrated designer.

Your mother? Yeah.

When schools stop doing that all the time,

It's like it's studying the buildings, trying to figure them out.

Moving along, what about the area of a triangle?

Finding a solution that worked was a process of trial and error.

Here's an example.

It took about ten years for me to be aware of this and get the right way.

Scorpions follow prey out of the sea. Slugs became snails.

Well, we use that great euphemism, trial and error, which is exposed to be meaningless.

Through trial and error, he found the right answer by chance.

And that's the way, ultimately after some ups and downs,

So instead, you can experiment with these different tools here by some process of guided trial and error, and at some point you will discover that one thing that you can do among several legitimate transformations is the following one.

It's a branch in the plan, so what we do is we search through this tree.

Misrepresentation of horizontal space in unilateral brain damage.

So we, by making a whole bunch of attempts, thousands of attempts, in that four year time period, we invented the concepts of the airplanes that we fly today.

Until recently, we haven't had to know exactly how a vaccine worked.

There's a lot of research and a lot of failure, trial and error I guess, more error that goes into each and every dish, so we don't always get it right, and it takes a while for us to be able to explain that to people.

And you see, there's a lot of back and forth in trying to make that happen, trying to figure it out

Sometimes you can look at this first digit and look at the first digit here and make an estimate.

let's have a systematic way of determining what's working and what's not you can solve your problem.

So it's going to go into it eight times, eight times is going to be less than 138, so we stick the eight here.

If someone told you to find the prime factorization of 589, you'll notice the problem feels harder.

Now you show me a successful complex system, and I will show you a system that has evolved through trial and error.

Information can't be found anywhere, so I created a manual myself through trial and error.

They've been around just as long and gone through just the same kind of trial and error to get here.
