The time: Many scholars over the centuries had pondered just how old our Earth might be, including an Irish archbishop named James Ussher. That is certainly specific; it is also spectacularly wrong. Loosely paraphrased: The Bible teaches us how to get to heaven; it is not a treatise on how the heavens move. Instead of counting the begats, scientists could count the layers. A fragment of meteorite retrieved from Canyon Diablo held the answer.
The Age of the Earth
As nature coerces us into a state of lockdown, a forced slowing down brought forth by the coronavirus pandemic, people across the world are rethinking not just their means of living, but also what will be the future of our planet and the various systems and practices that knowingly or unknowingly govern our everyday lives. Artists who have always been known to respond to the flux of times are no different. In recent times, many have been increasingly experimenting with sustainable materials, eco-friendly practices and concepts.
Anne Patterson, a New York -based artist, theatre and set designer and sculptor, it seems, rode the wave of sustainable art right before everything came to a halt. Trying to connect with her on skype as my slow internet speed poses disruptions, perhaps to follow through with the mood of the planet, I am finally able to connect with her in Rhode Island. Having studied architecture and theatre design in college, the spatial dynamics of the place are extremely crucial to her work.
To determine the age of the Earth – a seven-year effort – Patterson studied lead Patterson’s subsequent research showed that lead contamination dating.
Patterson was born in Mitchellville, Iowa, who spent his entire professional career at the California Institute of Technology Caltech. In collaboration with George Tilton, Patterson developed the uranium—lead dating method into lead—lead dating. Tilton, George R. Courtesy of National Academy of Sciences. Skip to main content. Biography of Clair Cameron Patterson, Download pdf resource. What is he known for discovering?
This value is derived from several different lines of evidence. Unfortunately, the age cannot be computed directly from material that is solely from the Earth. There is evidence that energy from the Earth’s accumulation caused the surface to be molten. Further, the processes of erosion and crustal recycling have apparently destroyed all of the earliest surface.

Event Calendar April Previous Next. Its origins are uncertain. Some see it as a celebration related to the turn of the seasons while others believe it stems from the adoption of the Gregorian Calendar which replaced the Julian Calendar. This food holiday is a classic favorite of many. The average American will have eaten over peanut butter and jelly sandwiches by the time they graduate from high school.
It is thought to be that the first reference of peanut butter paired with jelly on bread, was published in the United States in In the late ‘s, the price of peanut butter declined, and the sandwich became very popular with children.
Clair Patterson’s Early Life and Research
Claire C. Patterson’s biographer and peer George H. Tilton described him as energetic, innovative, determined and “modest about his own accomplishments. He received many scientific awards, and an asteroid discovered in is named in his honor. A peak in the Queen Maude Mountains in Antarctica also carries his name.
Clair Patterson determined the age of the Earth—and then he saved it. most celebrated minds: Willard Libby, the pioneer of carbon dating;.
You may have been aware that our Earth is as old as 4. But do you know who found out this fantastic figure first? The destiny rests on shoulders on a young man, Clair Patterson, who was a PhD student at the University of Chicago in the s. The first task for Patterson was to measure the concentration and isotope composition of lead inside the zircon, which is extremely useful for geological dating. This was a brilliant idea however followed by tough laboratory work.
It was found that no matter how crazy Patterson measured the concentration and isotope composition of lead in the zircon sample, disappointing results always showed up — exceeding values with poor reproducibility. Then, it was realized that there must be some lead coming from outside the lab or even the atmosphere that contaminated the samples and ruined nearly all the experiments!
To this end, Patterson began to clean his laboratory by hand, trying to wipe all the lead away from the working area. The hope just came along. It had been 7 years since the young man began to study the lead, and finally he made it! It appears to be a happy ending, however I would say, this is just the beginning.
How Old Is Earth?
Nineteenth century geologists recognized that rocks formed slowly as mountains eroded and sediments settled on the ocean floor. But they could not say just how long such processes had taken, and thus how old their fossils were. He came up with that figure by estimating how long it had taken for the planet to cool down to its current temperature from its molten infancy. But Kelvin didn’t, and couldn’t, know that radioactive atoms such as uranium were breaking down and keeping the planet warmer than it would be otherwise.
An older Earth At the dawn of the twentieth century, physicists made a revolutionary discovery: elements are not eternal.

After graduating with a degree in chemistry , Patterson completed his Ph. Using a newly developed form of lead dating, Patterson succeeded in his mission, giving us the estimate, 4. Patterson unwittingly discovered that modern industrial output, mainly car exhaust fumes, were adding devastatingly large amounts of lead to the air, at a rate that was sure to eventually cause widespread lead poisoning.
Patterson took on powerful oil and auto industry heads with a financial interest in silencing his work, and succeeded in demonstrating to the world the gravity of this problem. Patterson passed away in , at the age of Patterson can be found in the Grinnell College Libraries’ online catalog.

By the time Patterson was 31, his contribution to knowledge surpassed what most people can claim in a lifetime. Pursuing that achievement revealed the troubling specter of a poisoned modern environment and prompted even more important work.
The Clean Air Act and a global effort to remove lead from gasoline and other products grew out of the awareness his subsequent research and advocacy created. Lead is a neurotoxin, affecting the brain in ways that diminish IQ, disrupt neural communication, and decrease the size of the prefrontal cortex, inhibiting impulse control and motor functions. But because it was cheap and malleable—and because slaves and other laborers had the most direct contact—lead remained essential to many amenities.
