We are the most powerful nation on earth. No external power, no terrorist organization, can defeat us. But we can defeat ourselves by getting caught in a quagmire.
What I'm interested in is the conversations going on about the Anthropocene and what it means to view ourselves as a part of Earth's geological history.
Saudi Arabia was, until just a few years ago, probably one of the most safe countries on earth. And now the paper is daily full of activities and shootouts between Islamists who supported Osama bin Laden and the government there.
I'm a staunch believer that we are in an earth cycle. There's no question the planet is changing, and the fact that the Mayans had an end date and their history talks of change, I find that fascinating.
Of all celestial bodies within reach or view, as far as we can see, out to the edge, the most wonderful and marvellous and mysterious is turning out to be our own planet earth. There is nothing to match it anywhere, not yet anyway.
I like Canadians. Who doesn't like Canadians? It's amazing! They're the friendliest people on earth.
During the 20th century, we came to understand that the essence of all substances - their colour, texture, hardness and so forth - is set by their structure, on scales far smaller even than a microscope can see. Everything on Earth is made of atoms, which are, especially in living things, combined together in intricate molecular assemblages.

You will never cease to be the most amazed person on earth at what God has done for you on the inside.
Like Confucius of old, I am so absorbed in the wonder of the earth and the life upon it, that I cannot think of heaven and the angels.
