3,700-year-old Babylonian stone tablet gets translated, changes history

They were doing trigonometry 1500 years before the Greeks.

Dr. Daniel Mansfield and his team at the University of New South Wales in Australia have just made an incredible discovery. While studying a 3,700-year-old tablet from the ancient civilization of Babylon, they found evidence that the Babylonians were doing something astounding: trigonometry!

Most historians have credited the Greeks with creating the study of triangles' sides and angles, but this tablet presents indisputable evidence that the Babylonians were using the technique 1,500 years before the Greeks ever were.

Mansfield and his team are, understandably, incredibly proud. What they discovered is that the tablet is actually an ancient trigonometry table.

Mansfield said:

"The huge mystery, until now, was its purpose – why the ancient scribes carried out the complex task of generating and sorting the numbers on the tablet. Our research reveals that Plimpton 322 describes the shapes of right-angle triangles using a novel kind of trigonometry based on ratios, not angles and circles. It is a fascinating mathematical work that demonstrates undoubted genius."

"The tablet not only contains the world's oldest trigonometric table; it is also the only completely accurate trigonometric table, because of the very different Babylonian approach to arithmetic and geometry. This means it has great relevance for our modern world. Babylonian mathematics may have been out of fashion for more than 3,000 years, but it has possible practical applications in surveying, computer graphics and education. This is a rare example of the ancient world teaching us something new."

The tablet predates Greek astronomer Hipparchus, who has long been regarded as the father of trigonometry. Mansfield's colleague, Norman Widberger, added:

"Plimpton 322 predates Hipparchus by more than 1,000 years. It opens up new possibilities not just for modern mathematics research, but also for mathematics education. With Plimpton 322 we see a simpler, more accurate trigonometry that has clear advantages over our own."
"A treasure trove of Babylonian tablets exists, but only a fraction of them have been studied yet. The mathematical world is only waking up to the fact that this ancient but very sophisticated mathematical culture has much to teach us."

People were understandably excited by the news.

Some mathematicians actually think studying the Babylonians back then could help us improve the way we do trigonometry today.


Of course, there were the haters...

But all in all, Twitter users were pretty impressed with the Babylonians' skills.

And they figured it out 3,700 years ahead of me...and counting.— Marty (@Marty) 1503631905

Congratulations to Dr. Mansfield and his team on their incredible discovery... and for making trigonometry exciting!

10 anti-holiday recipes that prove the season can be tasty and healthy

Balance out heavy holiday eating with some lighter—but still delicious—fare.

Albertson's

Lighten your calorie load with some delicious, nutritious food between big holiday meals.

True

The holiday season has arrived with its cozy vibe, joyous celebrations and inevitable indulgences. From Thanksgiving feasts to Christmas cookie exchanges to Aunt Eva’s irresistible jelly donuts—not to mention leftover Halloween candy still lingering—fall and winter can feel like a non-stop gorge fest.

Total resistance is fairly futile—let’s be real—so it’s helpful to arm yourself with ways to mitigate the effects of eating-all-the-things around the holidays. Serving smaller amounts of rich, celebratory foods and focusing on slowly savoring the taste is one way. Another is to counteract those holiday calorie-bomb meals with some lighter fare in between.

Contrary to popular belief, eating “light” doesn’t have to be tasteless, boring or unsatisfying. And contrary to common practice, meals don’t have to fill an entire plate—especially when we’re trying to balance out heavy holiday eating.

It is possible to enjoy the bounties of the season while maintaining a healthy balance. Whether you prefer to eat low-carb or plant-based or gluten-free or everything under the sun, we’ve got you covered with these 10 easy, low-calorie meals from across the dietary spectrum.

Each of these recipes has less than 600 calories (most a lot less) per serving and can be made in less than 30 minutes. And Albertsons has made it easy to find O Organics® ingredients you can put right in your shopping cart to make prepping these meals even simpler.

Enjoy!

Alabama woman who married her stepbrother and has 2 kids shares their crazy love story

“It happens more than people would think! Glad I’m not alone!”

via Girl_Meets_Bro/TikTok

Lindsay and Caleb have an interesting history together.

In a story that would make a fantastic, albeit long, country song, Lindsay Brown and her husband Cade of Alabama have found love even though they are stepsiblings who were once banned from seeing each other by their parents.

Lindsay shared the dramatic saga on TikTok, where she has nearly 3,000 followers.

It all began in 2007 when Linday was 14 and Cade was 16, and the couple would secretly meet at her house. However, on the fourth night they were together, Lindsay’s mother walked in on them and Cade had to run out of the house in his birthday suit.

"He grabbed his keys, his phone, he did not grab his clothes,” Lindsay said in a TikTok post. “He ran through the yard, up the street to his truck naked. Then he drove home and snuck in his house naked and his parents never knew any of that happened."

Kids in 1966 shared their predictions for the year 2000 and it's fascinating to see now

In many ways, the future turned out much brighter than these youngsters expected it to.

BBC Archive/Facebook

Thankfully, this girl's prediction was way off.

The idea of predicting the future has been the subject of countless books, movies and televisions shows (and is basically the basis of all gambling). Outside of a few uncanny instances, no one can tell exactly what the future holds, especially for the world at large. But people sure love to predict it anyway.

The BBC shared a video compilation of kids in 1966 sharing what they imagine the year 2000 would be like, and their predictions are fascinating. After five or six kids share, it becomes clear what some of the most pressing concerns of the 1960s were. Some kids thought we'd have bombed ourselves into oblivion. Others believed we'd be so overpopulated we would be packed like sardines and wouldn't be able to build houses anymore.

Not all of the predictions were so dark. Some kids had some hilarious predictions about cabbage pills and robots. Others thought we'd have better cures for diseases and less segregation among the races, which we have.

New Anchor Leslie Horton was told she looked pregnant by a regular viewer.

Canadian news anchor Leslie Horton, 59, was moments away from doing her routine traffic report when she got an unnecessary, unsavory email from a viewer.

In true online troll fashion, the male viewer wrote, “Congratulations on your pregnancy. If you’re going to wear old bus driver pants, you can expect emails like this.”

Horton could have kept quiet, but instead she used her live segment to make a pretty epic response that went viral online.

The beautiful thing that happens in Amsterdam if you die and have no one to attend your funeral

The Lonely Funeral project was started by poet Frank Starik, who wrote, "Everyone—and this is the point—every person deserves respect."

Canva

Every life deserves to at least be acknowledged.

Funerals can be many things—a sombre mourning, a celebration of life, a time for family to honor a loved one—but one thing they should never be is unattended.

But the reality is that some people simply don’t have people. Maybe they’re estranged from their family and have outlived all their friends. Maybe they fell into a life of drug addiction and lost all of their close connections. Maybe no next of kin can be found or they just happen to die in a life stage when they have no one around to attend their funeral. Whatever the reason, some people's send-offs from earthly existence are purely legal affairs with no personal touches whatsoever.

Two decades ago, some poets in the Netherlands decided that was an unacceptable ending for a human life. In 2001, a poet named Bart Droog began attending the funerals of people who had no one to attend them and honoring the dead with a poem based on whatever was known about their life. A year later, Dutch poet and artist Frank Starik took the idea even further, launching The Lonely Funeral project to ensure that someone who cares consciously acknowledges the life of a person who has died.
