“My first customer was a lunatic. My second had a death wish.” — Karl Benz We want to get safer. We invest enormous resources in making the world a safer place. Sometimes, though, it doesn’t seem like we’re making much progress, especially when we’ve just experienced a catastrophic event. Instead, it seems like we just [...]
“It’s very hard for all of us, when we’ve committed ourselves to a particular interpretation, to change our minds.” — Donald Johanson We were recently asked if a steam boiler was a PSM-covered process.

“Maybe tone it down with the explosions.” — Michael Bay Most of what we know about explosions is wrong. Most of what we “know” about explosions is what we’ve learned from the movies, which is the only thing called an explosion that we ever see. But what we see in the movies are not explosions, [...]
“You may hate gravity, but gravity doesn’t care.” — Clayton Christensen In May 1946, a scientist at Los Alamos was demonstrating the criticality of plutonium.

“At the end of this day, one shall stand, one shall fall.” — Optimus Prime, Transformers: The Movie I have never been to a process plant that could continue running without electrical power.

“I don’t worry about the bullet with my name on it. Can’t do anything about that. It’s the bullet addressed to ‘Occupant’ that I worry about.” — Drew Schmidt I don’t get as much junk mail as I used to. Now, I get junk emails and junk texts. When I do get junk mail, however, [...]

Farley Building at the corner of Eighth Avenue and 33rd Street in Manhattan convinced the [...]
“We do not learn from experience…we learn from reflecting on experience.” — John Dewey There are too many celebrities and philosophers to count who have talked about the importance of their mistakes in shaping them. Many seem quite pleased, even proud, of the mistakes they’ve made and their ability to rise from them and go [...]
“Simplicity is prerequisite for reliability.” — Edsger Dijkstra For most of my life, I have struggled to keep down to a healthy weight. It didn’t help when someone told me, “Losing weight is simple.
