In fact, some of the most groundbreaking scientific discoveries were made by Catholic clergy.
Here are the top 5 scientific breakthroughs made by priests…🧵 (thread)
5) Atomic Theory (Boscovich Model)
Roger Boscovich, a Croatian physicist, astronomer, and mathematician, was a Catholic priest in the Jesuit order. His model of the atom, the “Boscovich Model,” was a forerunner to modern atomic theory.
His theory was an attempt to find a middle way between Newton’s theory of gravity and Gottfried Leibniz's metaphysical theory of monad-points (points of original substance).
In addition to physics, Boscovich made significant astronomical observations; in particular the moon.
4) Seismology
One of the pioneers in the field of seismology was Fr. Giuseppe Mercalli in the late 19th and early 20th century.
He’s famous for developing the Mercalli Intensity Scale which measures the intensity of seismic shaking caused by earthquakes.
Though the Richter scale superseded his scale for magnitude measurement, the Mercalli scale remains the method for assessing the impact of earthquakes on people and buildings.
Mercalli’s commitment to science and his faith exemplify the harmony between the two realms.
3) Genetic Theory
Gregor Mendel, “the father of modern genetics,” was a 19th-century Augustinian friar and abbot. He developed Mendelian genetic theory by observing the inherited traits in pea plants, paving the way for our modern understanding of heredity.
Mendel’s discoveries were initially ignored. Notably Charles Darwin had no idea about Mendel’s work. It’s possible had he known, genetics would have developed much earlier.
The significance of his work was only finally realized after his death.
2) The Big Bang
The Big Bang theory of the universe’s origin was first posited by Georges Lemaitre, a Belgian astronomer. physicist, and priest. His theory shocked the scientific community when it was first published in 1927, but has since been widely accepted.
Lemaitre’s model upset the millennia-old belief of an eternal cosmos. His theory implied that everything came from an ultra-dense, tiny point, and its expansion birthed time and space.
Contrary to common belief, it was anti-religious sentiment that prevented the Big Bang theory from broad acceptance early on.
Atheist scientists were repulsed by the Big Bang's creationist overtones—it seemed too similar to the creation story in the Book of Genesis.
1) Heliocentrism
Nicolaus Copernicus was an early proponent of heliocentrism, the theory that the sun centered the solar system.
It’s possible that Copernicus, a Renaissance-era polymath dubbed the “father of modern astronomy,” was also a Catholic priest.
Copernicus held various positions within the Church, and the Catholic Encyclopedia claims he was ordained since in 1537 he was a candidate for the episcopal seat of Warmia, a seat that required ordination. Some scholars contest whether he was ever actually ordained though.
The idea that science and religion are at odds is a fairly new concept.
Despite the modern misconception, it’s historically been religious institutions, especially the Catholic Church, who have been the main drivers of scientific advancement in the West.

All empires repeat the same cycle, says 20th-century historian John Glubb.
He observed that for the past 3000 years every civilization has followed the same 6 stages before decline—what are they?🧵
Sir John Bagot Glubb was a British soldier and author who served as the commanding general for Transjordan's Arab Legion from 1939 to 1956.
In his later years he wrote about geopolitics and world history, and penned a succinct description of how civilizations rise and fall…
Glubb’s 1978 work, “The Fate of Empires and the Search for Survival,” is an idea-dense essay that argues all great empires follow an eerily similar pattern.
From observing 11 distinct cultures, Glubb draws some intriguing conclusions that have implications for modern society.
On May 20th, 1910, nine kings gathered at Windsor for the funeral of King Edward VII.
The photograph they took is a stark reminder of how drastically European leadership has changed—the men pictured remain symbols of a bygone era of monarchy.
Who were they?🧵
King Haakon VII of Norway (top row, far left)
Ruled from November 1905 until his death in 1957. After the 1905 dissolution of the union between Sweden and Norway, he became the first independent Norwegian monarch since Olaf II in 1387.
Tsar Ferdinand of the Bulgarians (top row, second from left)
Ruled as Tsar during the tumultuous First World War. After a series of military setbacks in 1918, he abdicated the throne in a bid to save the monarchy. His eldest son succeeded him, becoming Tsar Boris III.
Galileo called him “superhuman”. Tesla said he was the “ideal” inventor. And da Vinci was directly inspired by him.
Simply put, Archimedes was the greatest engineer and mathematician of the ancient world.
Here’s why...🧵(thread)
Born around 287 BC, Archimedes was an inventor, mathematician, astronomer, and engineer from the city of Syracuse in Sicily.
Very little is known of Archimedes’ life other than his discoveries and inventions, of which there were many.
The ancient historian Polybius was the first to reference Archimedes about 70 years after his death, describing various war machines that the inventor built including catapults, a giant crane that destroyed ships, and various stone-throwing machines.
Charles "the Hammer" — perhaps no figure deserves the title “defender of Western civilization” as much as him.
A warrior-statesman, he not only crushed foreign invasions but also laid the foundation for medieval Europe🧵
Born an illegitimate son to Pepin of Herstal, ruler of a few Frankish territories, Charles (c. 688–741 AD) enjoyed the youth of an aristocratic warrior, but was never expected to inherit his father’s rule.
Between royal courts and battlefields, he was trained as a warrior, receiving instruction in sword fighting, horseback combat, and military strategy.
Modern man has a severe case of amnesia—he’s forgotten the immense wisdom of the past.
Luckily, it can be rediscovered through great literature.
12 old books that will make you wiser… 🧵(thread)
12. Enchiridion, Epictetus
Epictetus never wrote down anything himself, but his student Arrian collected his teachings, recording them for future generations. His lessons enlighten the reader on matters regarding ethics and achieving inner freedom.
11. The Prince, Niccolo Machiavelli
Machiavelli’s classic is a 16th-century handbook on effective governance. It’s an essential read for anyone who wishes to understand the motivations and reasoning behind great leaders from the past or savvy politicians today.
