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!

From political science to joining the fight against cancer: How one woman found her passion

An unexpected pivot to project management expanded Krystal Brady's idea of what it means to make a positive impact.

Krystal Brady/PMI

Krystal Brady utilizes her project management skills to help advance cancer research and advocacy.

True

Cancer impacts nearly everyone’s life in one way or another, and thankfully, we’re learning more about treatment and prevention every day. Individuals and organizations dedicated to fighting cancer and promising research from scientists are often front and center, but we don’t always see the people working behind the scenes to make the fight possible.

People like Krystal Brady.

While studying political science in college, Brady envisioned her future self in public office. She never dreamed she’d build a successful career in the world of oncology, helping cancer researchers, doctors and advocates continue battling cancer, but more efficiently.

Brady’s journey to oncology began with a seasonal job at a small publishing company, which helped pay for college and awakened her love for managing projects. Now, 15 years later, she’s serving as director of digital experience and strategy at the American Society of Clinical Oncology (ASCO), which she describes as “the perfect place to pair my love of project management and desire to make positive change in the world.”

As a project manager, Brady helps make big ideas for the improvement of diagnosing and treating cancer a reality. She is responsible for driving the critical projects that impact the lives of cancer researchers, doctors, and patients.

“I tell people that my job is part toolbox, part glue,” says Brady. “Being a project manager means being responsible for understanding the details of a project, knowing what tools or resources you need to execute the project, and facilitating the flow of that work to the best outcome possible. That means promoting communication, partnership, and ownership among the team for the project.”

At its heart, Brady’s project management work is about helping people. One of the big projects Brady is currently working on is ASCO’s digital transformation, which includes upgrading systems and applications to help streamline and personalize oncologists’ online experience so they can access the right resources more quickly. Whether you are managing humans or machines, there’s an extraordinary need for workers with the skillset to harness new technology and solve problems.

The digital transformation project also includes preparing for the use of emerging technologies such as generative AI to help them in their research and practices.

“Most importantly, it lays the groundwork for us to make a meaningful impact at the point of care, giving the oncologist and patient the absolute latest recommendations or guidelines for care for that specific patient or case, allowing the doctor to spend more time with their patients and less time on paperwork,” Brady says.

In today’s fast-changing, quickly advancing world, project management is perhaps more valuable than ever. After discovering her love for it, Brady earned her Project Management Professional (PMP)® certification through Project Management Institute (PMI)—the premier professional organization for project managers with chapters all over the world—which she says gave her an edge over other candidates when she applied for her job at ASCO.

“The knowledge I gained in preparing for the PMP exam serves me every day in my role,” Brady says. “What I did not expect and have truly come to value is the PMI network as well – finding like-minded individuals, opportunities for continuous learning, and the ability to volunteer and give back.”

PMI’s growing community – including more than 300 chapters globally – serves as a place for project managers and individuals who use project management skills to learn and grow through events, online resources, and certification programs.

While people often think of project management in the context of corporate careers, all industries and organizations need project managers, making it a great career for those who want to elevate our world through non-profits or other service-oriented fields.

“Project management makes a difference by focusing on efficiency and outcomes, making us all a little better at what we do,” says Brady. “In almost every industry, understanding how to do our work more effectively and efficiently means more value to our customers, and the world at large, at an increased pace.”

Project management is also a stable career path in high demand as shown by PMI research, which found that the global economy will need 25 million more project managers by 2030 and that the median salary for project managers in the US has grown to $120K.

If you’d like to learn more about careers in project management, PMI has resources to help you get started or prove your proficiency, including its entry-level Certified Associate in Project Management (CAPM) certification program. For those interested in pursuing a project management career to make a difference, it could be your first step.

This daughter knew exactly what to get her dad for Secret Santa

Many people dream of somehow being able to pay their parents back for the sacrifices made for them during childhood. Whether that’s something physical, like paying off their mortgage, or simply being the best version of ourselves to make them absolutely proud.

For Lindsay Moore, it was finding a “prized possession” her dad once gave up to help the family, and returning it to him once again.

Moore still vividly remembers being only seven years old when she saw her father walk into a comic book store to sell a Dan Marino rookie football card from his first season with the Miami Dolphins.

Therapist shares science-backed phrases that parents can use to gently defuse a meltdown

It's perfectly natural to want to raise your voice when a toddler is having a tantrum. But experts say there is a better way.

Finger pointing is actually NOT one of the suggested strategies

When your toddler has a meltdown, it's perfectly natural to want to fly off the handle.

There's nothing more infuriating than a small human repeatedly demanding something that's physically impossible for you to give them, or wailing because you had to punish them after repeatedly telling them to knock it off.

"I CREATED YOU, YOU LITTLE MONSTER. I CAN DESTROY YOU," you might want to say (though you never would). You love your kids — of course you do — but damn if they aren't the best at pushing you to your breaking point.

Brielle Asero lost her job after 2 months.

TikTokker Brielle Asero, 21, a recent college graduate, went viral on TikTok in October for her emotional reaction to the first day at a 9-to-5 job. The video, which received 3.4 million views, captured the public’s attention because it was like a cultural Rorschach test.

Some who saw the video thought that Asero came off as entitled and exemplified the younger generation’s lack of work ethic. In contrast, others sympathized with the young woman who is just beginning to understand how hard it is to find work-life balance in modern-day America.

“I’m so upset,” she says in the video. "I get on the train at 7:30 a.m., and I don't get home until 6:15 p.m. [at the] earliest. I don't have time to do anything!" Asero said in a video.
