Watching a whole cluster of friends, and my own mother, die over quite a short space of time convinced me that purely materialist 'explanations' for our mysterious human existence simply won't do - on an intellectual level.

One of the world's most successful and yet mysterious companies in the world, Samsung Electronics, has been operating without its leader for months and likely will continue to do so for some time to come.

What makes Samsung so mysterious is that it's not altogether clear who leads the company or what its leaders do. The company follows an avowedly Confucian model of consensus-driven decision-making, values bone-crushingly hard work, and shows tremendous deference to the founding Lee family, despite its lack of a controlling interest in its shares.

People have to respond to the characters and respond to the situations that they're in. That said, it still has to be a compelling narrative that drives along and keeps people coming back week after week. So really, with any successful show you could name, there has to be a mysterious blend of both of those.

We've known for a long time that the universe is expanding. But about 15 years ago, my colleagues and I discovered that it is expanding faster and faster. That is, the universe is accelerating, and that was not expected, but it is now attributed to this mysterious stuff called dark energy which seems to make up about 70 percent of the universe.

We don't work for the government. We don't carry guns. We don't chase aliens. We are a man and a woman. The similarities end there... If 'X-Files' and 'Touched by an Angel' crashed on 'Highway to Heaven,' you'd have 'Mysterious Ways.'

I've always been interested in oral traditions and mythological stories and legends from antiquity that have to do with nature, attempts to explain mysterious or puzzling, or very striking phenomena from nature. Things that people observed or heard about in nature.

Life is too mysterious to try to map it out. I've certainly lived long enough to know it will take you places you never thought it would take you - and some of those places are kind of wonderful.
