The truth is rarely pure and never simple.

The details are not the details. They make the design.

In the context of computational learning, the concept of 'probably approximately correct' (PAC) learning provides a framework for understanding the efficiency and feasibility of learning algorithms.

The only way to make sense out of change is to plunge into it, move with it, and join the dance.

Start where you are, with what you have. Make something of it and never be satisfied.

I believe in the power of storytelling to change perspectives and open hearts.
