The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

So I was trying to get to something.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

Do you have a problem with the way we do addition?

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

Don't know that.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

We do do things where sometimes we can divide by zero.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

We have concepts like the point at infinity where you can complete a structure that the original structure can't accommodate an operation, but you can complete it to a larger system in which that thing does become sensible.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

So as an example of the one times one, assume that Terrence doesn't have a big problem with addition because addition doesn't have the division by zero problem.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

It is the case that if you take any two numbers, A and B, two real numbers, right?

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

Make them positive.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

And take the natural logs of those two numbers and add those together.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

Then you take the exponent of that.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

So we haven't done a times operation at all.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

Right.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

The exponential of the ln of A plus ln of B. That is equal to A times B. In other words, addition and multiplication are what we would say is isomorphic, or an ordinary person would say exactly the same thing.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

So in other words, if you don't allow me multiplication, but you would allow me because you like waves.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

So with waves, you need exponentials and you need natural logarithms.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

There's no way of changing the law of multiplication and accepting the law of addition because they're the same system.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

The precise statement would be that the positive real numbers under multiplication with the identity element being the multiplicative identity being one are isomorphic to the total real numbers under addition with the additive identity being zero.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

And the natural logarithm and exponential are group homomorphisms that connect the two with one being the other's inverse.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

So by the principle of explosion, the reason that people are in part going to freak out about your stuff is that we have a vulnerability.

The Joe Rogan Experience
#2171 - Eric Weinstein & Terrence Howard

And that vulnerability says that from a single contradiction, if you can sneak one contradiction through TSA, the entire airport collapses.
