I did play the guitar and sing; I was in a band called The Estrogens: three females and one very brave guy.

I read about eastern philosophy and religion and existentialism. All that introspective thinking got me thinking about the great beyond. That turned my sights from inwards to outwards, and I started becoming interested in the makeup of the universe, and I started reading about astronomy, planets, and galaxies.

The Saturn system is a rich planetary system. It offers mystery, scientific insight, and obviously splendour beyond compare, and the investigation of this system has enormous cosmic reach... just studying the rings alone, we stand to learn a lot about the discs of stars and gas that we call the spiral galaxies.

Every type of ring behavior we have seen around Jupiter, Uranus, or Neptune can be found in orbit around Saturn. And Saturn's ring system offers the greatest promise of understanding processes in operation within all disk systems, not just those found around planets.

The thrill of science is the process. It's a social process. It's a process of collective discovery. It's debate, it's experimentation and it's verification of claims that might be false. It's the greatest foundation for a society.

I have issues with anyone who tries to claim that science is unworkable - creationists who deny evidence for past history, yet are happy to benefit from the products of the methodology that they otherwise deny.

Thanks to the fact that the Earth isn't a perfect sphere, and invoking a bunch of Newtonian physics, you can deduce that our planet wobbles, too, taking roughly 26,000 years to trace out a small circle on the sky, a phenomenon known as precession.

We wanted a pet food based on sound scientific principles and truth, not marketing hype.
