Sometimes the universe surprises you.

A few months ago, I received an email from independent filmmaker Frank Huguenard. Having read some of my posts on the science of consciousness, Frank wanted to know if I'd consider being interviewed for a film on that...

I'm a boomer, so I missed the greatest existential crisis of the 20th Century: The Second World War. My Dad, however, was in the thick of it, helping mop up after the Battle of the Bulge.

Global Warming or Climate Chaos: What's in a Name?

(45) Comments | Posted March 5, 2015 | 4:04 PM

This winter has set record lows in many states, a fact the editor of our conservative local newspaper, and others of his ilk, must be relishing. "There's no global warming," I can imagine him crowing. "It's all a liberal hoax." Such distorted logic reveals either an appalling ignorance of the...

"I've heard some folks try to dodge the evidence by saying they're not scientists -- that we don't have enough information to act [on climate change]. Well, I'm not a scientist, either. But you know what? I know a lot of really good scientists at NASA, and NOAA, and at...

Global Divestment Comes of Age

"It makes no sense to invest in companies that undermine our future. To serve as custodians of creation is not an empty title; it requires that we act, and with all the urgency this dire situation demands." -- Desmond Tutu

What Ferguson Says About America

(27) Comments | Posted December 7, 2014 | 3:59 PM

"Those who make peaceful revolution impossible will make violent revolution inevitable." -- John F. Kennedy, 1962

One might think that, by turning Martin Luther King, Jr., into a cultural icon and electing a black president, America has bid farewell to its racist past. Recent events in Ferguson, MO, New York,...

The GOP Simultaneously Cries 'Wolf' and 'The Sky Is Falling'

Despicable. That's the only word for it.

I refer to the recent official email "Responding to the Ebola Crisis" of October 17 from my congressional representative, Bob Goodlatte, of Virginia's 6th District.

It begins by stating that "Ebola now spreading in the United States is of extreme concern [emphasis added]."...

Toward a Post-Materialistic Science

(66) Comments | Posted October 1, 2014 | 12:39 PM

The latest issue of Explore -- the Journal of Science and Healing -- contains a bombshell of an essay. It's titled "Manifesto for a Post-Materialist Science," and it could be to science what Luther's 95 Theses were to religion.

Tipping Point: The People's Climate March

"If the planet dies, all causes are lost causes." -- Anonymous

Humanity's fate hangs on a tight race between two tipping points: a scientific one and a cognitive one.

Scientists use the term "tipping point" to refer to a runaway feedback loop that, when triggered, abruptly and irreversibly changes...

Watergate: American Democracy's Finest Hour

"Okay, Houston, we've had a problem here." -- Apollo 13 astronaut Jack Swigert

When was NASA's finest hour? Most would say, "The Apollo moon landing."

As a bit of an insider, I have a different take. NASA's finest hour, hands down, was the ill-fated Apollo 13 mission.

Occupy the Tea Party

(2) Comments | Posted August 1, 2014 | 12:41 PM

At first blush, the Tea Party and Occupy Wall Street appear as bookends: opposing grass-roots movements on the political right and left, respectively. At second blush, the Tea Party seems the more successful. In the 2010 mid-term elections, one-third of Tea Party-backed candidates won, reclaiming the House for Republicans. And...

Soft Landing or Crash and Burn? The Choice Is Ours

Not until 1804 did the Earth's human population first exceed one billion. Between 1804 and 2014, a 210-year period spanning just three consecutive human lifetimes, population skyrocketed: to 2 billion in 1927, 4 billion in 1974, and 7 billion at the end of 2011. What spurred such explosive growth?
