National Parks and National Park Cities

How Energy Flow Shapes the Evolution of Life

Nick Lane will explore the importance of energy flow in shaping life from its very origins to the flamboyant complexity around us, and ask whether energy flow would direct evolution down a similar path on other planets.

The High Energy Universe

View the sky through an x-ray telescope and the conception of the universe changes dramatically. Black holes are best seen in x-rays, because impinging gas collides with the black hole at near light speed, resulting in intense x-ray and gamma ray emission.

The Clockwork God: Isaac Newton and the Mechanical Universe

Isaac Newton saw his demonstration of the regularity of the universe as having great religious significance. Newton’s ideas were initially seen as very supportive of religion; yet within 50 years, they were being seen in a very different light.
