Albert Visser: The absorption law for slow provability
The lecture was held within the framework of the Hausdorff Trimester Program: Types, Sets and Constructions. Abstract: The absorption law for slow provability states that, if it is provable that A is slowly provable, then A is provable. We give a simple proof of the absorption law for a v

This is a short video for people who haven't seen a Heyting algebras before. There is really nothing special in it that doesn't show up in wikipedia or ncatlab. I just wanted to review it before we use them. Errata: *at 3:35: there the law should read (a and (a or b) ), not (a and (a and

Francesco Ciraulo: Notions of Booleanization in pointfree Topology
The lecture was held within the framework of the Hausdorff Trimester Program: Types, Sets and Constructions. Abstract: Boolean algebras play a key role in the foundations of classical mathematics. And a similar role is played by Heyting algebras for constructive mathematics. But this is

Review of arithmetic with decimals II | Year 9 Maths 5 | NJ Wildberger
We continue our review or arithmetic with decimal numbers. How do we multiply two decimal numbers? How do we divide one decimal number by another? The trick is to realize that by suitably multiplying and dividing by powers of 10, these problems essentially reduce to arithmetic with ordinar

How do we add matrices. A matrix is an abstract object that exists in its own right, and in this sense, it is similar to a natural number, or a complex number, or even a polynomial. Each element in a matrix has an address by way of the row in which it is and the column in which it is. Y
