When writing the Principia Mathematica, Isaac Newton declared his hand on most of the big questions in physics. He outlined the nature of space, explained the motions of the planets and conceived the operation of gravity. He also laid down the law on time declaring:
“Absolute, true, and mathematical time, of itself and from its own nature, flows equably without relation to anything external.”
For Newton time was absolute and set apart from the universe, but with the theories of Albert Einstein time became more complicated; it could be squeezed and distorted and was different in different places.
Time is integral to our experience of things but we find it very difficult to think about. It may not even exist and yet seems written into the existence of absolutely everything.

Guido van Rossum, creator of Python, talks about language design, favorite Python projects, and the future of Python.
Programming has long been the domain of logic and order, but with the ubiquity of programming languages in our lives and the growth in tools to help you code, there has come a newfound ability for self-expression and creativity through code.
Relating anecdotes from the past, Kent Beck, the father of Extreme Programming and JUnit, reflects back on the impact his ideas have had in the last 20 years, especially with respect to the history of Test Driven Development (TDD), Design Patterns, and Extreme Programming (XP). According to him, good ideas take about that much time to mature and come to fruition.
He regrets how patterns have become a tool in the arsenal of the software developer to solve a programming problem whereas he intended it to be one that would create more space for the user who was to be affected by the software. Reminiscing about the birth of patterns, he draws analogies between architecture in general and software architecture.
Finally he discusses the factors that affect the successful acceptance of an idea.
