Everything Everywhere Daily: History, Science, Geography & More - J. Harlen Bretz: Proving Theories Via Outliving Your Critics (Encore)

Starting point is 00:00:00 Hey everyone, this is Gary. Just want to let you know that this week I'm going to be off at a podcasting conference because every so often even I need to take a break. I've lined up some episodes that statistically I know most of you have never listened to, so they'll all be new to you. I'll be back again with brand new episodes on August 28th. Many people have an idealized view of how science works. They think that someone makes a discovery or publishes a paper, then everyone acknowledges their discovery and everyone moves along to the next thing. Science. However, that isn't quite how things work in reality. The real advancement of science can be quite messy, and one man learned this the hard way. Learn more about Jay Harlan Brett's and how he changed a scientific discipline through determination and longevity on this episode of Everything Everywhere Daily.

Starting point is 00:00:47 What if your perceptions about the past were wrong? ThruLine is a podcast that takes you back in time to uncover the parts of the story that may have gone unnoticed. It effectively turned day into night. and how it shaped the world now. Time travel with us every week on the Thurline podcast from NPR. The German Nobel Prize winning physicist Max Planck said, quote, A new scientific truth does not triumph by convincing its opponents and making them see the light,

Starting point is 00:01:36 but rather its opponents eventually die and a new generation grows up that is familiar with it, unquote. Or, as it is put more colloquially, science advances one funeral at a time. convincing people that deeply held beliefs they hold are wrong is very difficult to do. This is true in almost any aspect of life, and science is no exception. When a certain worldview is established, overturning it is hard, even if the evidence is on your side. No one knew this better than Jay Harlan Brett's. Brett's was a high school biology teacher in Seattle, took an interest in geology, and then turned that interest into a PhD in the field and a teaching position at the University of Chicago.

Starting point is 00:02:15 While he was living in Washington, he took an interest in the topography of eastern Washington State. In 1922, he began doing fieldwork in the Columbia Plateau and several of the erosional features which were found there. He went to that area every year for the next seven years, and over a period of nine years, he published 15 papers on the subject. He dubbed the area the channeled scablands. If you get a chance, as soon as you're done listening to this, go do a search for Washington Scablands and take a look at some of the images. to get an idea of what the area looks like. It's actually really impressive. According to his studies and years spent analyzing the area, he came to the conclusion that the formations in this region could only have been carved out by a massive cataclysmic flood.

Starting point is 00:03:02 The problem was that the area today is a high desert and that there was no obvious source of water. Little did Brett's know that this theory would consume the next 40 years of his life. The problem with Brett's theory is that it flew in the field. face of the conventional wisdom of the geology establishment. The predominant worldview of geologists at the time was known as gradualism or uniformitarianism. This held that geologic change occurred slowly and gradually over long periods of time. It was established by the father of modern geology James Hutton in the 18th century. This theory isn't wrong per se. Many geological changes happen in exactly this way. We can so accurately measure the earth now that we can tell how fast

Starting point is 00:03:44 North America and Europe are drifting away from each other, and how fast mountains are growing or shrinking. Brett's was proposing a catastrophic change. The idea of catastrophic changes like floods, meteor strikes, earthquakes, or hurricanes, altering the landscape was anathema to the idea of gradualism. In 1927, Brett's gave a presentation to the Geological Society of America in Washington, D.C. The presentation turned out to be an ambush by established geologists. They packed the room to try to shut this idea down for good and discredit Brett's. The leading geologists were mostly from elite East Coast universities, and they didn't see Brett's as being sufficiently

Starting point is 00:04:21 credentialed. They also didn't know where the water would have come from, and of course, it upended the biggest assumption of their entire discipline at the time, gradualism. One U.S. Geological survey scientist named Joseph Pardy sat in on the presentation in Washington and believed what Brett's was saying. He had actually been to the scablands, whereas most of Brett's critics had never been there and never would visit. Moreover, he thought he knew where the water for Brett's flood came from. The source of water, according to Pardy, was a giant glacial lake which sat on top of the glacier over western Montana during the last ice age. The lake was dubbed Glacial Lake Missoula. The lake would have had a volume of water larger than Lake Ontario, the fourth largest

Starting point is 00:05:04 of the Great Lakes. When the glacial ice melted enough, the lake started to drain, which caused a catastrophic flood. The entire massive volume of water shot out, and the incredible force of that water flow caused the unique features of the scablands. Features like giant 20-meter high ripples, which could not have been caused by gradual erosion over time. Over the next several decades,

Starting point is 00:05:28 the debate raged on. Brett's slowly had younger geologists accept his theories, and slowly his critics retired. Over the years, more and more evidence supported his theory, and better understanding of the last ice age developed. By the 1950s, enough evidence had come in that the general consensus had changed. There were detailed aerial images that became available, and eventually satellite images from NASA provided even more evidence.

Starting point is 00:05:53 Some of his critics eventually did visit the scablands themselves. One critic, James Galooly, commented, How could anyone have been so wrong? A 1965 geological report of the region finally concluded that Brett's was right all along. 40 years after he initially published his first paper on the topic. At the age of 82, he had been vindicated. After the paper came out, one of his critics sent him a telegram, which read, quote, We are all now catastrophes.

Starting point is 00:06:23 Brett said about the report, quote, After 30 years and 30 papers in self-defense, and more than 30 people who vigorously denied my theory, it did my heart good like medicine, unquote. The final thing which put the cherry on top of Brett's achievement, occurred in 1979. At the age of 96, he received the Penrose Medal from the Geological Society of America, the organization's highest award. After receiving the award, he reportedly told his son, quote, All my enemies are dead, so I have no one to gloat over.

Starting point is 00:06:58 Brett's passed away in 1981 at the age of 98. Brett's idea on catastrophism have been widely accepted now, and it paved the way for other theories, such as the extent. of the dinosaurs from the Chicholub Crater in Mexico. Today, if you visit Dry Falls State Park in Washington State, at the visitor center, you'll see a bronze plaque dedicated to J. Harlan Brett's. On it is one of his quotes from 1928, which says, Ideas without precedent are generally looked upon with disfavor, and men are shocked if their conceptions of an orderly world are challenged.

Starting point is 00:07:37 The associate producer of Everything Everywhere Daily is Thor Thompson. Today's five-star review comes from listener Scott Jordan over at Apple Podcasts. He writes, The Most Enjoyable Podcast, Love It. OMG, I Am Addicted. Basically, it's a combination of short, about seven minutes long, and very interesting stories about historical facts told by Gary Arndt. Once I started listening, I couldn't stop.

Starting point is 00:08:00 Before I knew it, I listened to about ten in a row. They are extremely well-researched and the storytelling is engaging. I highly recommend them. I can't wait to get caught up and then begin listening in a row. real time. Great job, Gary. Well, thank you, Scott. And for those of you who don't know, Scott Jordan is the Scott in Scotty Vest, the ads for whom you've heard many times on the show. Stay tuned in future episodes for something special for Everything Everywhere listeners. And remember, if you leave a five-star review, you too can have your review read on the show.
