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

via UNSW

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.

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

## How to help your eyes in a world that makes you stare at a screen all day

True

Innovation is awesome, right? I mean, it gave us the internet!

However, there is always a price to pay for modernization, and in this case, it’s in the form of digital eye strain, a group of vision problems that can pop up after as little as two hours of looking at a screen. Some of the symptoms are tired and/or dry eyes, headaches, blurred vision, and neck and shoulder pain1. Ouch!

Eye strain from staring at devices is a widespread issue. Most people work, play, and maintain relationships through screens, which averages out to 6 hours and 35 minutes per day (and that’s in addition to work or school)! That translates to 46 hours and 5 minutes per week, or 2,402 hours and 55 minutes per year.2

With numbers like these, attention to eye health is more important now than ever; our dependence on technology certainly isn’t going anywhere. And just like innovation brought us technology, innovation also holds the key to combating the effects it has on our bodies. Here are some key suggestions from eye care professionals to help reduce common symptoms of digital eye strain. Spoiler alert: none of them involve wearing glasses!

You can find some relief by taking a 20-20-20 break: every 20 minutes, look at something 20 feet away for 20 seconds. It’s easy to remember because we all want 20/20 vision, and it’s a good excuse to look out the window.

This simple tweak to your work area can really improve your posture, as well as the amount of strain on your eyes. A win-win!

Brightness levels also play into how hard our eyes have to work. Our screen brightness should match our surroundings, especially during the evening hours.

Say hello to Biofinity Energys® contact lenses!

These contact lenses are specifically made to address eye dryness and tiredness caused by digital devices. Digital Zone Optics® lens design and Aquaform® Technology are two innovations that when combined help with the tiredness and dryness that can be caused by digital eye fatigue.

Additionally, Biofinity Energys® monthly replacement contact lenses are designed to help our eyes better adapt for a more comfortable wearing experience3. This part is tricky because contacts can be hard to adjust to, and trust me—no one wants what feels like gritty sandpaper in there. Comfort is key!

## Someone asked strangers online to share life's essential lessons. Here are the 17 best.

### There's a bit of advice here for everyone—from financial wisdom to mental health tips.

Failure is a great teacher.

It’s true that life never gets easier, and we only get continuously better at our lives. Childhood’s lessons are simple—this is how you color in the lines, 2 + 2 = 4, brush your teeth twice a day, etc. As we get older, lessons keep coming, and though they might still remain simple in their message, truly understanding them can be difficult. Often we learn the hard way.

The good news is, the “hard way” is indeed a great teacher. Learning the hard way often involves struggle, mistakes and failure. While these feelings are undeniably uncomfortable, being patient and persistent enough to move through them often leaves us not only wiser in having gained the lesson, but more confident, assured and emotionally resilient. If that’s not growth, I don’t know what is.

Reddit user u/G_man252 asked people to share their own life lessons “learned the hard way,” and the answers, though varied, all touched on something useful that everyone can probably relate to. Especially those of us who have had the blessing of living long enough to gain a lot of hard-won knowledge.

Below are 17 of the best lessons that all of us either have learned, are trying to learn or will learn soon enough. Reading them isn’t necessarily the same as experiencing them, but there is still some comfort in knowing they are all part of what it means to be human.

Read. Be enlightened. Or at the very least, be soothed and entertained.

## CEO who makes over \$1,000,000 a year vows only to give her kids one Christmas gift

### She's setting an example.

Co-op CEO Shirine Khoury-Haq.

The CEO of Co-op, one of the UK’s largest supermarket chains has made an important statement about excess at a time when many families are struggling in the UK.

The Daily Mail reports that Shirine Khoury-Haq, the head of a company with over 3900 retail locations says she’s giving her twin, six-year-old daughters one present each this Christmas because she could not “in good conscience” give them more while millions of families struggle with inflation and high energy prices.

Khoury-Haq makes over £1 million (\$1,190,000) a year after bonuses, so she pledged to give her family's present money to those in need. “It just feels like excess, given what’s happening in the world. In good conscience, I can’t do that in my own home,” Khoury-Haq said according to The Guardian.

“The rest of our budget will be given to Santa to provide presents for children whose parents can’t contribute to the elves,” she continued. “We’re going to go out shopping for those other presents and [we will] send them to Santa.”

According to the Sunday Times, one of her daughters would like a Paw Patrol toy and the other, a Barbie.

Much like America, people in the UK are having financial hardships as inflation reaches a 40-year high. They are also dealing with exorbitant energy prices. Through July, natural gas prices in the UK were up 96% and electricity was up 54%.

Khoury-Haq’s company has also made sacrifices this holiday season to help those who are less fortunate. Co-op has decided to hand over all of its holiday advertising budget to Your Local Pantry shops. These community-based pantries across the UK are places where people can pay as little as £3.50 (\$4.20) a week to take at least ten grocery items.

“Whilst many of our competitors are also adapting their Christmas ads to reflect the mood of the nation in a cost of living crisis, we are going further by pulling our ad altogether,” Khoury-Haq said according to Retail Gazette.

“In doing so we will be shining a light on the need to support vital community causes, throughout the year and not just at Christmas, especially with a deep recession looming,” she continued.

Through their partnership, the Co-op and Your Local Pantry hope to help over 32,000 households over the next three years, saving them nearly £5 million (\$5,980,000) on shopping bills.

Khoury-Haq’s decision to give her kids one gift each on Christmas may not save everyone in the UK from their financial troubles but it sends an important message that people who are well off should consider. When millions of people are hurting, it’s not the time to flaunt your wealth or spoil your kids. Her gesture is a great reminder that hopefully inspires others to give as well.

When the going gets tough, it’s time for those who can afford it to be a great example to their kids and society-at-large by giving when people need it most. Because in the end, the spirit of giving is the true meaning of the holiday season.

## Chris Hemsworth's reaction to his daughter wanting a penis deserves a standing ovation

### Thor knew exactly how to handle it.

Chris Hemsworth and daughter.

In addition to being the star of Marvel franchise "Thor," actor Chris Hemsworth is also a father-of-three? And it turns out, he's pretty much the coolest dad ever.

In a clip from a 2015 interview on "The Ellen DeGeneres Show," Hemsworth shared an interesting conversation he had with his 4-year-old daughter India.

"My daughter's kind of envious of my boys," Hemsworth told Ellen. "She came to me the other day, and she's like 'You know, Papa, I want one of those things that Sasha and Tristan have.' And I'm like, 'What do you mean?' She said, 'You know the things in between their legs that you have.'"

Hemsworth said he tried to explain the differences between male and female bodies, but his daughter wasn't having it.

"She goes, 'I really want one!' Hemsworth said. "I'm like, 'A penis?' And she's like, 'I want a penis!'

And then, Hemsworth had the best possible response. He recalls:

She's four and I'm like, 'You know what, you can be whatever you want to be.' And she goes, 'Thanks, Dad.' Runs off into the playground and that was it.

And then, I cannot confirm, but I'm pretty sure the Ellen audience did this:

Major kudos to Hemsworth for taking a potentially awkward parenting situation and turning it into a lesson about love and acceptance.

## Cuban immigrant’s reaction to getting his first American paycheck has gone viral

### Before coming to the U.S. last year, Diaz made \$12 a month as a computer science teacher in Cuba.

The Cuban and American flags.

An Instagram post featuring Yoel Diaz, a recent Cuban immigrant, is going viral because it shows a powerful example of something many of us in America take for granted. The freedom to earn a paycheck for a day of honest labor.

In the video, Diaz is ecstatic after he opens his first paycheck after getting a job as a seasonal worker for UPS. CBS reports that before coming to the U.S. last year, Diaz made \$12 a month as a computer science teacher in Cuba.

"This is my first hourly paycheck that I feel every hour counted," he told CBS News. "That every hour of work has importance in my life and that I know I can work hard for something. I can't compare that emotion with anything. Because I never had that in my country."

The new job was a big change from life in Cuba where he had trouble filling his refrigerator. He told CBS News that sometimes he only had two items: "Water, water, water, five, ten eggs, water."

### "

“First paycheck in AMERICA!!! This is the American dream!!!” his wife Marissa Diaz of Pheonix, Arizona captioned the post. “There are no words to describe how proud I am of your courage to enter a country and a culture that is not yours. This content is a mini documentary not only for us but dedicated to the many immigrants who sacrifice everything to film what we just filmed. A little bit at a time, with hard work and dedication anything is possible in this country.

Diaz's video comes at a time when Cuba is facing some of its most difficult economic hardships since Fidel Castro's 1959 revolution. Widespread food and medicine shortages have led to protests in the streets, a rarity in the authoritarian country.

Diaz moved to America from Cuba to be with his wife whom he met as a child living in the communist country. After moving to the U.S., she shared stories of what life was like outside of Cuba. After the couple got together, Diaz had a choice: to stay in Cuba or go to the U.S. for greater opportunity.

"We want a future, we want a family... wherever you go I go,” he said. “This time, I finally can dream—I can help my family and this is the first step in my new life where I can be whoever I want now,” he said according to The New York Post.

On election day, Diaz shared why Americans should be grateful to have the ability to choose their leaders because where he is from, there is only one party. His perspective is important at a time when many Americans feel the country has been divided by political tribalism.

"Sometimes I see people fight with each other and they don't know the blessing they have. Just that you can think differently is a positive," he said in the video. "To Americans: Think about what you have. You Should stop fighting because it's something so beautiful. To think differently."

Diaz’s appreciation of his life in America is a great lesson to all of us who may take our unique freedoms for granted. America may not be a perfect place, but it’s still a country where people are free to pursue their dreams. Diaz’s story is also a wonderful reminder of the power America has to transform lives through immigration and that it should embrace that opportunity and give the gift to as many people as possible.
