# 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!

Over the past few years, rising supermarket prices have forced many families to make compromises on ingredient quality when shopping for meals. A recent study published by Supermarket News found that 41% of families with children were more likely to switch to lower-quality groceries to deal with inflation.

By comparison, 29% of people without children have switched to lower-quality groceries to cope with rising prices.

Despite the current rising costs of groceries, O Organics has enabled families to consistently enjoy high-quality, organic meals at affordable prices for nearly two decades. With a focus on great taste and health, O Organics offers an extensive range of options for budget-conscious consumers.

O Organics launched in 2005 with 150 USDA Certified Organic products but now offers over 1,500 items, from organic fresh fruits and vegetables to organic dairy and meats, organic cage-free certified eggs, organic snacks, organic baby food and more. This gives families the ability to make a broader range of recipes featuring organic ingredients than ever before.

“We believe every customer should have access to affordable, organic options that support healthy lifestyles and diverse shopping preferences,” shared Jennifer Saenz, EVP and Chief Merchandising Officer at Albertsons, one of many stores where you can find O Organics products. “Over the years, we have made organic foods more accessible by expanding O Organics to every aisle across our stores, making it possible for health and budget-conscious families to incorporate organic food into every meal.”

## Americans see gardening changes as 'plant hardiness zones' shift across half the U.S.

### Here's a quick tool to find out if your zone has changed due to warmer temperatures.

The USDA has issued a new Plant Hardiness Zone Map

Millions of American households have a garden of some sort, whether they grow vegetables, fruits flowers or other plants. Gardening has always been a popular hobby, but more Americans turned to tending plants during the height of the COVID-19 pandemic for both stress relief and to grow their own food so they could make less trips to the store. For many people, it's a seasonal ritual that's therapeutic and rewarding.

But a shift is occurring in the gardening world. Now, due to rising temperature data, half the country find themselves in a different "plant hardiness zone"—the zones that indicate what plants work well in an area and when to plant them. Gardeners rely on knowing their hardiness zone to determine what to plant and when, but they haven't been updated since 2012.

The U.S. Department of Agriculture updated its Plant Hardiness Zone Map in late 2023, months before people in most of the country start planning their planting. We saw the 10 hottest summers ever recorded in 174 years of climate data between 2014 and 2023, but hardiness zones are actually determined by the coldest winter temperatures each year. Winters are warming at an even faster pace than summers, according to nonpartisan research and communications group Climate Central, but that may or may not be the entire reason behind the zone changes.

The USDA acknowledges that some of the zone shifts could be due to climate change but cautions against using them as hard evidence for it since factors such as improved data collection also contribute to changes in the map.

Gardening can be a solo or community endeavor.

"Temperature updates to plant hardiness zones are not necessarily reflective of global climate change because of the highly variable nature of the extreme minimum temperature of the year, as well as the use of increasingly sophisticated mapping methods and the inclusion of data from more weather stations," the USDA wrote in November 2023. "Consequently, map developers involved in the project cautioned against attributing temperature updates made to some zones as reliable and accurate indicators of global climate change (which is usually based on trends in overall average temperatures recorded over long time periods)."

At the same time, Chris Daly, director of the PRISM Climate Group at Oregon State University that developed the map with the USDA, told NPR, "Over the long run, we will expect to see a slow shifting northward of zones as climate change takes hold."

As an example of zone shifting, Dallas, Texas, was classified as Zone 8a in 2012, when data showed the coldest winter temperature in the city was between 10 and 15 degrees Fahrenheit on average. In 2023, with data showing the coldest winter temps falling between 15 and 20 degrees Fahrenheit, it's been shifted to Zone 8b.

Some zone shifts resulted in moving to an entirely new zone number, such as Seattle shifting from Zone 8b to Zone 9a. The overall trend was for zones to be pushed northward, but not all areas saw a shift. NPR has a helpful tool here in which you can enter your zip code, see what zone your city was previously in, what zone it's in now, and the temperature changes that caused the shift.

The bottom line is if you have a gardening book with a hardiness zones map printed before 2024, it's time for an updated map. Or check online to see what zone you fall in now to give your garden the best chance of thriving this year.

## Mechanic warns that you should check on these 3 things before buying a used car

checking your car might be easier than you think.

Buying a used car is often the more sustainable and financially sound choice, but it does have its inherent risks. Even purchasing from a dealership doesn’t guarantee quality, or safety. NBC News previously reported that some “certified” pre-owned vehicles which had passed auto retailer AutoNation’s “precise inspection process” had unresolved recalls.

Bottom line: you don’t truly know how well the vehicle was taken care of. However, there are certain precautions we can take to ensure our investment is a wise one.

A man who goes by “Jackson The Mekanic” recently posted a now-viral video explaining the “three musts” that you need to check before pulling the trigger on a car purchase. Great news—all these things are easy to check, even without mechanic supervision.

1. Oil Level

"First, you pull out the dipstick," Jackson explains as he shows where to find it under the hood.

“It's very important to wipe it with a rag first, then re-insert the dipstick back in." After you pull it out again, you want to make sure the oil makes it to the “full” line. Also, make sure the car is off when you check.

@mekanic_jackson

2. Coolant Level

Coolant, also known as antifreeze, is a liquid that keeps a car's engine from overheating by transferring heat and preventing it from freezing or boiling. In the comments Jackson says that this is an important thing to check because low levels can indicate a leak.

To check coolant levels, Jackson says "There's two ways you can do this, you can check it directly from the radiator, or you can check it from the overflow tank."

To check from the radiator, you’ll need to lift open the cap, but keep in mind that you’ll need to wait until after the engine has cooled down to do so.

If the car is low on coolant, Jackson recommends you simply add a little water.

3. Brake Fluid Level

Jackson might have saved the most important for last.

"What you're looking [for] here is for color and for the level, so we can see this color looks nice and new, and is also topped up to the max,” he says while pointing to a full brake fluid tank.

For many of us, car upkeep can be overwhelming. But it’s a necessary skill, at least if you don’t rely on public transportation to get you everywhere you need to be. And certain aspects aren’t all that difficult to understand once we really pop open the hood and see what’s inside. And expert explanations like the ones Jackson offers certainly help.

If you’re looking for more of his advice—like how to replace a car battery, which cars to avoid to save money and diagnosing engine noises —follow Jackson on TikTok.

## It's hard to truly describe the amazing bond between dads and their daughters.

Being a dad is an amazing job no matter the gender of the tiny humans we're raising. But there's something unique about the bond between fathers and daughters.

Most dads know what it's like to struggle with braiding hair, but we also know that bonding time provides immense value to our daughters. In fact, studies have shown that women with actively involved fathers are more confident and more successful in school and business.

## You know how a picture is worth a thousand words? I'll just let these images sum up the daddy-daughter bond.

A 37-year-old Ukrainian artist affectionately known as Soosh, recently created some ridiculously heartwarming illustrations of the bond between a dad and his daughter, and put them on her Instagram feed. Sadly, her father wasn't involved in her life when she was a kid. But she wants to be sure her 9-year-old son doesn't follow in those footsteps.

"Part of the education for my kiddo who I want to grow up to be a good man is to understand what it's like to be one," Soosh told Upworthy.

There are so many different ways that fathers demonstrate their love for their little girls, and Soosh pretty much nails all of them.

Get ready to run the full gamut of the feels.

## Artist creates amazing inflatable shower curtain to help save water

### If you take long showers you’re in for a rude awakening.

Singing in the shower.

Are you the type of person who is always waiting on someone in the shower, or are you the one holding everyone up with your epic shower songs? Either way, Elisabeth Buecher has the perfect shower curtain for you. The London-based artist created an inflatable shower curtain that fills soft spikes with air if the shower is on too long. After four minutes of running water, a sensor on the tap triggers an inflator for the spikes, and the bather is immediately reminded that it's time to get out.

Buecher created the installation to raise awareness about water conservation.

"They aim at provoking a debate around water issues and making people more aware of their consumption," the artist said on her website.

## Asexuality is often misunderstood.

In general, it's believed to be the absence of any romantic interest, but asexual identity actually means that a person is not sexually attracted to anyone. Romantic feelings and the strength of those feelings can vary from person to person.

Currently, about 1% of adults have no interest in sex, though some experts believe that number could be higher. For a long time, information on asexuality was limited, but researchers recently have found information that gives us more knowledge about asexuality.

## Being asexual can be tough, though — just ask the artists from Empathize This.

To demonstrate, they put together a comic on asexuality, defining it as a sexual orientation, not a dysfunction:
