#### MCTM Keynote Part 1

This past December I gave a keynote talk at the Missouri Council of Teachers of Mathematics’ Conference. I’ve been thinking about the ideas I presented and wanted to share them more widely, so I turned them into a series of videos. 20 more words

#### PDE Constrained Optimization

Instead of optimization in a finite dimensional setting, or controlling the trajectory of the state as in optimal control, one can consider optimization of systems governed by partial differential equations (PDEs). 298 more words

#### Geometry

Laws of geometric figuresThe square:

laws of geometric figuresSquare:- square circumference = side x 4- side of the square = circumference ÷ 4- square area = side x sideAppointed:- Perimeter of the rhombus = side x 4Diamond rib = circumference ÷ 4Rhombus Area = (Large Diameter x Small Diameter) ÷ 2 – Large Diameter = (Area x 2) ÷ Small Diameter – Small Diameter = (Area x 2) ÷ Large Rectangular Diameter:- circumference of the rectangle = (length + width) x 2- length of the rectangle = (circumference ÷ 2) – width- width of the rectangle = (circumference ÷ 2) – length- Area of the rectangle = length x 2- length of the rectangle = area ÷ width- width of the rectangle = area ÷ lengthparallelogram:- parallelogram circumference = (base + leg) x 2 – parallelogram base = (circumference ÷ 2) – leg – parallelogram leg = (circumference ÷ 2) – base – parallelogram area = base x height – parallelogram base = area ÷ height – parallelogram height = area ÷ basetrapezoid:- trapezoidal area = [(large base + small base 9 ÷ 2] x height – trapezoidal height = (area x 2) …. 704 more words

#### Turing Machines

Mathematicians are highly ambitious people who never like to lose. For a long time, it was a popular belief that every mathematical problem is solvable, either theoretically or mechanically. 1,176 more words
