## Setting goals as a mathematician

I finished my eighth half marathon last weekend. Since I started running in 2004, I finished six marathons and several 10k and 5k races. I enjoy running longer distances. Although I’m not a competitive runner, I am proud of my running achievements.

Running gives me time to think. Mathematical proofs have popped into my head during training runs. Beyond that, running a long distance like a half or full marathon is a *goal*. A hard, but realistic goal that is feasible with the appropriate training.

Souvenirs of a hard run 21.1 K.

Goals form a critical part of every successful mathematician’s tool chest. They provide us a path forward, and without them, we lack direction. One of the things I have noticed with newly graduated doctoral students is that they often experience *post-PhD limbo*: there are no more formal expectations from their University or supervisor. Post-docs or fresh Assistant Professors either start…

## The Mathenæum – Mathematical explorations, games, and learning

The Mathenæum – “An Athenæum is a place for reading and learning, such as a library, a museum, or scientific academy. The term comes from the temple of the goddess Athene in ancient Athens, which was used for teaching. Building on this tradition, you are now visiting my online Mathenæum — a website devoted to mathematical exploration, learning, and fun!”

## 135th Carnival of Mathematics

Before we begin, let’s know our number-friend of this month. 135 is the smallest three-digit number that is the sum of its first digit and the square of its second digit and the cube of its third digit: $latex displaystyle{135 = 1 + 3^2 + 5^3}&bg=ffffff$.

Now, get hold of pen and paper, the carnival begins…

**Cross-Number Puzzle** – Numbrcise.com

This is a “medium” brainteaser to help you warm up. To play, you must fill in all the blank squares in the grid with numbers ranging from 1 to 9 in order to find a synchronized solution to a series of horizontal and vertical equations – all at once.
