It's hard to hide a ship. But during World War I, British artist Norman Wilkinson came up with a novel way to at least disguise what ships were doing, and thus help keep them safe from German U-Boats. His idea, which paired unpredictable patterns with bright, bold colors, was called dazzle camouflage (sometimes called “razzle dazzle camouflage”). Besides making it much harder for U-Boats to aim, it had an outsized impact on art and fashion. You can learn more about the inspired (and once top-secret) camo in Vox's new video below.

Sequoyah: The Man Who Saved the Cherokee Language

Sequoyah was fascinated by books and letters, enchanted by the way people could divine meaning from ink-stained scribbles on a written page. Born in the 1760s in what is now Tennessee and trained as a silversmith and blacksmith, the Cherokee man never learned how to read or write in English, but he always knew that literacy and power were intertwined.

During most of Sequoyah's lifetime, the Cherokee language was entirely oral. According to the Manataka American Indian Council, a written language may have existed centuries earlier, but the script was supposedly lost as the tribe journeyed east across the continent. Sometime around 1809, Sequoyah began working on a new system to put the Cherokee language back on the page. He believed that, by inventing an alphabet, the Cherokee could share and save the stories that made their way of life unique.

At first, some Cherokee disliked Sequoyah’s idea. White people were encroaching further on their land and culture, and they were resistant to anything that resembled assimilation. Some skeptics saw Sequoyah’s attempts to create a written language as just another example of the tribe becoming more like the oncoming white settlers—in other words, another example of the tribe losing a grip on its culture and autonomy.

Sequoyah, however, saw it differently: Rather than destroy his culture, he saw the written word as a way to save it. According to Britannica, he became convinced that the secret of white people's growing power was directly tied to their use of written language, which he believed was far more effective than collective memories or word-of-mouth. In the words of Sequoyah, "The white man is no magician." If they could do it, so could he.

Sequoyah became further convinced of this in 1813, after he helped the U.S Army fight the Creek War in Georgia. For months, he watched soldiers send letters to their families and saw war officers deliver important commands in written form. He found the capability to communicate across space and time profoundly important.

Sequoyah's first attempt to develop a written language, however, was relatively crude by comparison. He tried to invent a logographic system, designing a unique character for every word, but quickly realized he was creating too much unnecessary work for himself. (According to historian April Summit's book, Sequoyah and the Invention of the Cherokee Alphabet, his wife may have attempted to burn an early version of his alphabet, calling it witchcraft.) So Sequoyah started anew, this time constructing his language from letters he found in the Latin, Greek, and Cyrillic alphabets, as well as with some Arabic numerals.

Sequoyah became more reclusive and obsessive, spending hour upon hour working on his alphabet. According to the official website of the Cherokee Nation, people outside his family began whispering that he was meddling with sorcery. By 1821, Sequoyah was too busy to pay the gossip any mind: He was teaching his six-year-old daughter, Ayokeh, how to use the system.

As one story goes, Sequoyah was eventually charged with witchcraft and brought to trial before a town chief, who tested Sequoyah’s claims by separating him and his daughter and asking them to communicate through their so-called writing system. By the trial’s end, everybody involved was convinced that Sequoyah was telling the truth—the symbols truly were a distillation of Cherokee speech. Rather than punish Sequoyah, the officials asked him a question: Can you teach us how to read?

Once accepted by the Cherokee, Sequoyah’s 86 character alphabet—which is technically called a syllabary—was widely studied. Within just a few years, thousands of people would learn how to read and write, with many Cherokee communities becoming more literate than the surrounding white populations. It wasn’t long before the Cherokee language began appearing in books and newspapers: First published in 1828, The Cherokee Phoenix was the first Native American newspaper printed in the United States.

Sam Houston, the eventual governor of Texas, admired Sequoyah's achievement and reportedly told him, “Your invention of the alphabet is worth more to your people than two bags full of gold in the hands of every Cherokee." Today, while the Cherokee language is now considered endangered by UNESCO, Sequoyah's system remains a landmark innovation—and a source of hope for the future.

Newly Uncovered Galileo Letter Details How He Tried to Avoid the Inquisition

Galileo Galilei was one of the Roman Catholic Inquisition’s most famous targets. As a result of his outspoken support for the theory that all the planets, Earth included, revolve around the Sun, the Catholic Church charged him with heresy and he spent the last years of his life under house arrest. Galileo was well aware that he was on the Church’s hit list, and a newly discovered letter shows that at one point, he tried to tone down his ideas to avoid persecution, according to Nature and Ars Technica.

The letter in question, written in 1613, solves a long-held mystery for Galileo scholars. It was found in the library of the Royal Society, where it has been for at least 250 years.

Galileo’s beef with the Catholic Church came about because of his support for heliocentrism—the idea that the solar system centers around the Sun—as advocated in Nicolaus Copernicus’s book De Revolutionibus. Galileo’s scientific writings clearly endorsed Copernicus’s theory of the world, including in personal correspondence that was widely disseminated, and in some cases, he directly questioned the scientific merit of Biblical passages.

In 1613, Galileo wrote to a friend and former student named Benedetto Castelli who was then teaching mathematics at the University of Pisa. The letter was a long treatise on Galileo’s thoughts on Copernicus’s ideas and religion, arguing that science and astronomy should not be overpowered by religious doctrin . (He would later expand this into his Letter to the Grand Duchess Christina.) As with many of Galileo’s writings at the time, the letter was copied and disseminated widely, and eventually, a friar named Niccolò Lorini forwarded it to the Inquisition in Rome in 1615.

This is where things get tricky. Galileo claimed that the version of the letter Lorini sent was doctored to be more inflammatory. He sent a less controversial version of the letter to a friend, saying that it was the original document and should be forwarded to the Vatican, essentially to clear his name. But scholars have never been able to be totally sure if he was telling the truth about the letter being doctored.

This newly discovered letter suggests that he was lying, and that he himself was looking to tone down his rhetoric to appease the Catholic Church and keep authorities from quashing the spread of heliocentric ideas. The original copy found in the Royal Society archives shows changes to the wording in what appears to be Galileo’s handwriting. The seven-page letter, signed “G.G.,” includes changes like swapping the word “false” for the more slippery “look different from the truth,” changing “concealing” to “veiling,” and other edits that seek to tone down the rhetoric that inflamed Church leaders. The wording and handwriting corresponds to similar writing by Galileo at the time. Based on this finding, it seems that Galileo did seek to make his ideas more palatable to the Catholic Church in the hopes of escaping persecution by the Inquisition.

Discovered on a research trip by science historian Salvatore Ricciardo of Italy's University of Bergamo, the letter may have been overlooked in the Royal Society archives because it was cataloged as being dated October 21, 1613 rather than the date it actually bears, December 21, 1613. However, it’s unclear how it came to the Royal Society in the first place. The document is the subject of a forthcoming article by Ricciardo and his colleagues in the Royal Society journal Notes and Records, according to Nature.

The minor changes Galileo made did not successfully hold off the Church’s crackdown on heliocentrism. In 1616, the Inquisition ordered Galileo to stop teaching or defending the theory, and several of his books were subsequently banned. He would stand trial again almost two decades later, in 1633, on suspicion of holding heretical thoughts. He was found guilty and sentenced to house arrest, where he remained until his death in 1642.
