A sieve .
a sieve because there's, you know, hundreds of negotiators there and they all share them with executives from various industries in their countries.
Now we stop the sieve at seven, and we could keep going sieve by 11 or 30, but it turns out that we don't have to.
- Take the traditional sieve of Eratosthenes again, when we're sieving with just one prime, we just have an over two.
This is like a sieve .
Because the more primes we sieve by, the more those error terms start to accumulate and we just can show this.
It was probably what's called the sieve of Eratosthenes which was the algorithm to try and find all the prime numbers under a certain number.
We're going to use the sieve of Eratosthenes to try and find all the prime numbers.
Now the normal version of this tool is called the sieve of Eratosthenes, and it works something like this.
- But there's also a second wave to visualize this sieve .
And so you end up with this beautiful visualization of the sieve .
And so this is the part where he adapted his sieve , to find a case where both N and N plus two are prime.
In general, if you sieve by K primes, you get roughly two to the power K minus one error terms, but we can drop the one
But that is where we run into a problem with the sieve we've been using.
- So, run a sieve by fewer factors, only up to N to the power one over 10.
Because Brun, didn't sieve by all the primes, there were some survivors that weren't prime at all, but numbers with many prime factors,
And then you can just drain them through a sieve and they're ready to go.
washed through the brain like water through a sieve without leaving any lasting value behind.
So you would take a colander or a sieve and line it with-- a lot of people use cheese cloth, like a double or triple thickness of cheese cloth.
So it's a great liner for your sieve or colander.
And it's kind of basically this really cool sieve .
And you only need to-- when doing the sieve , go to the square root of the number that you're seiving which is root of 100 which is 10.
Now in general, if we keep the sieve going up to some prime P, which is less than the square root of N,
So, this means that while in the ordinary sieve a prime P removes about one out of every P numbers, the twin prime sieve removes two.
- And so what Brun eventually realized is that if you weaken the sieve , if you don't sieve all the way up to square root X,
By using another approach, known as sieve methods, he proved that every sufficiently large even number is the sum of a prime and a number that's either a prime,
So we really think the human mind is a bit like a sieve , right?
But today, we're going to use this sieve contraption here.
And that like flattening of space where where everything can be like sieved through the device,
It just brings in water, sieves water right through its body, extracting the plankton from the water for its food.
But with Brun's method, you would only need to sieve up to 10 billion to the power one over 10, which is just 10.
The point is we want it to stick in the brain as long as possible before it slides through the sieve .
And they evolve these extraordinary antennae, almost like molecular sieves , to track the molecules as they fly upwind.
Because, first of all, like sieves rather than buckets, we forget a lot of the information that's given to us in school.
And at the time, I had a professor whose name was Brian Sieveking.
- So, Eratosthenes, has this idea that you only need to sieve out the primes that are at most square root, the size of the number.
Say you wanted to find all the prime numbers up to 10 billion, then using the square root method, you would need to sieve up to the square root of 10 billion,
So it's called seabura, so you can take pork, or any type of fat and boil it and press it through a sieve .
And Jenna, do you mind handing me that chinois, that big sieve that's down on the end?
You would heat up milk, add some acid to it, and then it would curdle, and then you would put it in a sieve , and
And that like flattening of space where where everything can be like sieved through
