Math Photo: Slope Field in the Sky

Slope Field in the Sky

I finally made it down to the new Fulton St. subway station.  Such a beautiful view from below, like the slope field of a differential equation.

Each of the 88 glass blades of the Sky Reflector-Net is positioned to channel sunlight down throughout the station at different times of day and days of the year.  Maybe next year I’ll stop by on the summer solstice.

Bridges Math and Art 2015

Bridges 2015I am excited to once again be participating in the Bridges Math and Art conference this summer!

The Bridges organization has been hosting this international conference highlighting the connections between art, mathematics, and computer science since 1994.

I have participated in several Bridges conferences, and my experiences there have greatly influenced me as a mathematician and a teacher.

This year, I’ll be presenting a short paper, “Monte Carlo Art Using Scratch“, chairing a short paper session, and exhibiting a photograph in the Bridges Mathematical Art Gallery.

You can view the Bridges 2015 program here, see the entire 2015 Art Exhibit here, and learn more about the conference and the Bridges organization here.

Math Haiku: Geometry Class

I personally enjoy writing, and as a math teacher I love getting my students writing about math.

One of my favorite writing assignments for students is math-themed haiku.  The rigid constraints of haiku make it an easy exercise, it allows students to access and interact with mathematical ideas in a different and creative way, and the elegance and efficiency of the for evoke the character of mathematics itself.

Here are some selections from this year’s Geometry class.  Enjoy!

We are both equal

We look exactly the same

We are congruent

Postulates assumed

Leading to certain theorems

Web of proof and math

Three lines have converged

Meeting at a single point

They are concurrent

Scalene triangles

Angles are dissimilar

Sides are unalike

CPCTC

A simple explanation

For congruent things

Math is easy now

Calculators do all the work

Sit back and relax
