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.
"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...
Find someone who loves you as much as this guy dislikes a hypothesis about Babylonian math: http://www.sciencemag.org/news/2017/08/ancient-babylonian-tablet-may-contain-first-evidence-trigonometry\u00a0\u2026pic.twitter.com/c5yO8LmjhE— Miles Brundage (@Miles Brundage) 1503605001
But all in all, Twitter users were pretty impressed with the Babylonians' skills.
And we're over here trying to figure out how to do trig with our TI-83s... man I love it when the ancients show what real intelligence is.— Kenny Hayse (@Kenny Hayse) 1503633184
Congratulations to Dr. Mansfield and his team on their incredible discovery... and for making trigonometry exciting!
A breastfeeding mother's experience at Vienna's Schoenbrunn Zoo is touching people's hearts—but not without a fair amount of controversy.
Gemma Copeland shared her story on Facebook, which was then picked up by the Facebook page Boobie Babies. Photos show the mom breastfeeding her baby next to the window of the zoo's orangutan habitat, with a female orangutan sitting close to the glass, gazing at them.
"Today I got feeding support from the most unlikely of places, the most surreal moment of my life that had me in tears," Copeland wrote.
"I visited Schoenbrunn zoo in Vienna whilst on a mini-break with my partner and son. We nipped in to see the orangutans at the end of our day who were happily playing in the enclosure, so I went to the window for a closer look and sat down by the window so my lb could see the orangutan who was roughly 5/6ft away. She then got up, carried a piece of cloth to the window and sat down with me. She looked directly into my eyes then placed her hand up as if to touch my son. I was in awe of this beautiful creature already."
"My son wanted feeding and as it was quiet I fed him whilst I sat there. The way the orangutan reacted took my breath away she kept looking at me, then my son then back again," she continued. "She sat with me for approximately half an hour, kept stroking the glass and lay down next to me as if to support and protect me.
I had to share this because my mind was blown. We may be a species apart but breastfeeding connected us today in a once in a lifetime moment that will stay with me forever. I'm also incredibly lucky that my partner caught all of this on video 💕"
The Facebook page added a story about a gorilla being taught to breastfeed by women from La Leche League, an organization dedicated to supporting breastfeeders:
"Did you know that women from La Leche League once taught a mother gorilla to breastfeed? The Mamma gorilla had been born and raised in captivity and didn't know what to do with her firstborn, and her baby sadly died. When she next became pregnant, breastfeeding women volunteered to sit beside the gorilla's enclosure and breastfeed their babies, showing the gorilla what to do. When the gorilla gave birth, a volunteer came over and breastfed her baby, showing Mamma gorilla what to do, step by step. Mamma gorilla watched, and then copied, and went on to successfully feed her baby"
The story has been shared more than 37,000 times, with many commenters stating how beautiful and moving it was. Others, while appreciating the beauty of the animal encounter, expressed sadness at seeing such a creature in captivity. As with practically every post about animals in zoos, debate broke out over whether or not zoos are helpful or harmful to the animals they house.
And like most debates, people's opinions fall along a broad spectrum. Some feel that zoos are the best way for people to learn about animals first-hand, which leads them to care more about protecting them in the wild. Some acknowledge that captivity isn't ideal, but that many animals die individually or go extinct as species without the work they do. Some feel that it's always wrong to keep an animal in captivity, no matter what. Even animal experts don't agree on this front.
And not all zoos are created equal. Many zoos have moved more toward a rehabilitation and conservation model, and there's no question that many animals who have been raised in captivity would not survive if they were suddenly released into the wild. There's also the issue of whether trying to limit natural breeding in captivity falls under the ethical treatment of animals, as breeding is a natural animal instinct. And what about the animals that have gone extinct in the wild and can only be found in zoos? There are a million questions with a million unclear answers when it comes to zoos.
However there is one thing most can agree on. Whether or not you think zoos are helpful or harmful, necessary or not, they largely exist today because of human activity mucking with nature. The same nature that compels this creature to connect with a human mother, despite her unnatural surroundings. The same nature that humans are destroying to get palm oil for our cookies and soaps, leading orangutans to the brink of extinction. The same nature that we are all responsible for protecting.
Whether we find this story sweet or sad or something in between, the reality for orangutans in the wild is worth our attention. Visit www.theorangutanproject.org/ to learn more about how to help.

92-year-old Norma had a strange and heartbreaking routine.
Every night around 5:30 p.m., she stood up and told the staff at her Ohio nursing home that she needed to leave. When they asked why, she said she needed to go home to take care of her mother. Her mom, of course, had long since passed away.
Behavior like Norma's is quite common for older folks suffering from Alzheimer's or other forms of dementia. Walter, another man in the same assisted living facility, demanded breakfast from the staff every night around 7:30.
Jean Makesh, CEO of Lantern assisted living facilities, says he meets folks with stories like these every day. It's their stories that inspired him to make some changes at Lantern.
"I thought I knew a lot about elderly care. The more and more time I was spending with my clients, that's when I realized, 'Oh my god, I have no clue.'"
Confusion is common in Alzheimer's patients, but Makesh knew there had to be some way to minimize these conflicts.
A big believer in the idea that our environment has an enormous effect on us, he started thinking big — and way outside the box.
"What if we design an environment that looks like outside?" he said. "What if I can have a sunrise and sunset inside the building? What if I'm able to have the moon and stars come out? What if I build a unit that takes residents back to the '30s and '40s?"
And that was just the beginning. He also researched sound therapy. And aromatherapy. And carpet that looked like grass. No idea was off-limits.
What he came up with was a truly unique memory-care facility. And after testing the concept in Lantern's Madison, Ohio, facility, Makesh is opening two new locations this year.
Instead of rooms or units, each resident gets a "home" on a quiet little indoor street reminiscent of the neighborhoods many of them grew up in.

Instead of a boring panel ceiling, residents look up and see a digital sky, which grows dimmer late in the day to help keep their biological clocks in tune.
Throughout the day, nature sounds and fresh aromas like peppermint or citrus are piped in.
Some studies have shown that this kind of aromatherapy may indeed have some merits for improving cognitive functioning in Alzheimer's patients.
There's even a little "main street" where residents can gather.
For Makesh, this isn't just about making patients comfortable, though. He wants to change how we think about the endgame of severe dementia.
The insides of the rooms aren't too shabby, either.
Makesh said one of the frustrating shortcomings of most nursing facilities is that they create conflicts with unnatural environments and schedules, and they try to solve them by throwing antipsychotic and anti-anxiety medications at patients. In other words, when someone has severe dementia, we often give up on them. From there, they stop getting the engagement their brain needs to thrive.
Of course, we're a long way from a cure for Alzheimer's.
But Makesh's project shows that when we think strategically about altering the environment and focus on helping people relearn essential self-care and hygiene skills, the near-impossible becomes possible.
"In five years, we're going to [be able to] rehabilitate our clients where they can live independently in our environment," he said. "In 10 years, we're going to be able to send them back home."
He knows it's a lofty goal. And whether he'll meet it remains to be seen. But in the meantime, he's proud to own one of the few places that offers something pretty rare in cases of severe dementia: hope.
