Great Deceiverism 101
Posted in For Your ConsiderationUnreasonable Faith
If someone can’t tell you how they would know that they are wrong, they don’t have a clue whether they are right.

One Step at a Time
Posted in For Your ConsiderationUnreasonable Faith
Once seemingly incomprehensible, the origin of life no longer seems such a mystery. Most of what once appeared as roadblocks are turning out to be superhighways.

The Mind’s Siren Call
Posted in For Your ConsiderationUnreasonable Faith
Being certain lights up our brains like a junkie’s next hit. Literally. Unfortunately, being certain and being right are two very, very different things.

Constrained Hallucinations
Posted in For Your ConsiderationUnreasonable Faith
The unique worlds we each consciously inhabit – the only worlds we will ever experience – are constrained hallucinations, products of hypothesis testing by our predictive brains.

Entropy Redux
Posted in For Your ConsiderationUnreasonable Faith
A month’s worth of sunlight could pay the entropy bill for a billion years of biological evolution. Entropy is evolution’s best friend.

Entropy’s Rainbow
Posted in For Your ConsiderationUnreasonable Faith
Entropy is often maligned as the enemy of order. In truth, without the inexorable march of entropy, the universe would be a very boring place.

Cassandra Smiling
Posted in For Your ConsiderationUnreasonable Faith
On a cold day in April, 2017 scientists gathered in Washington DC and cities around the world for the March for Science. Their message was a single powerful idea. Truth is not a political expediency. Reality cannot be ignored. In the year that has followed the vital importance of that message has only grown.

EPA Rehash
Posted in Thoughts
When I look at NASA’s new Administrator, Jim Bridenstine, it is his fellow Oklahoman Scott Pruitt’s EPA that jumps to mind. As politically uncomfortable science is pushed aside, NASA’s history of nonpartisanship appears headed for an abrupt end. Will a strongly partisan NASA have a target on its back?
The Hermeneutics of Bunk
Posted in For Your ConsiderationUnreasonable Faith
Some years ago, NYU physicist Alan Sokal wondered whether anti-science postmodernists could recognize politically-correct-sounding nonsense even if he rubbed their noses in it. The unwitting subjects of the Sokal Hoax jumped at the bait.

A Dunning-Kruger Universe
Posted in For Your ConsiderationUnreasonable Faith
Some people are sure they know more than the experts, but it can take a lot of knowledge to realize just how wrong an idea is.

Our Need to Know
Posted in CoachingThoughtsUnreasonable Faith
The human brain craves the sensation of knowing like a drug addict craves the next fix. If real knowledge is uncomfortable or not at hand, we are quite content to just make something up, then convince ourselves it’s real. In a world where knowledge matters, that’s dangerous.
A Saguaro’s universe
Posted in For Your Consideration
The iconic saguaro cactus gives the desert an otherwordly beauty. That beauty does not exist in isolation. It embodies the fascinating and awe-inspiring processes that have shaped the universe, going all the way back to the Big Bang itself.

Over his 30 year career as an internationally known astrophysicist, Dr. Jeff Hester was a key member of the team that repaired the Hubble Space Telescope. With one foot always on the frontiers of knowledge, he has been mentor, coach, team leader, award-winning teacher, administrator and speaker, to name a few of the hats he has worn. His Hubble image, the Pillars of Creation, was chosen by Time Magazine as among the 100 most influential photographs in history.
Repairing the Hubble Space Telescope
Before launch, the Hubble Space Telescope was being touted as the greatest advance in astronomy since Galileo first pointed a telescope at the heavens. But it didn’t take long to discover that it had a serious flaw. Hubble’s mirror was exquisite. It was just the wrong shape, leaving it unable to make sharp images of the heavens.
Hubble fell victim to a W.A.G. In the face of budget, schedule and political pressures, very smart people turned a blind eye to a wealth of evidence of Hubble’s problems when they could have been easily fixed. The result was a $1.5 billion disaster.
Excerpts from BBC’s “Miracle on Orbit.”
Almost overnight, Hubble became the butt of jokes on late night television. Jay Leno in particular took us to task. “What sound does a space turkey make? ‘Hubble Hubble Hubble'”
I have the dubious distinction of being the guy sitting at the computer console with live nationwide television cameras looking over my shoulder when the first images from Hubble were radioed to Earth. I was also a member of the science team responsible for the Wide Field and Planetary Camera 2, the instrument that would ultimately restore Hubble to its original promise. With the eyes and weight of the world on us, we had the task of making sure that it worked.
The scene in the operations room when the first image from the repaired Hubble was radioed back to Earth.
It is amazing how close that effort came to succumbing to the same sorts of errors responsible for Hubble’s original failure.
Those experiences shaped my thinking throughout the remainder of my career. They form the kernel of my message today. Success doesn’t come from looking for reasons to think that we are right. Success comes from looking for the things that tell us we might be wrong.
