“Today I Learned”: 101 Interesting Things About The World That People Didn’t Know Until Recently (New Pics)

Learning never stops. If you’re open and energetic, you can find opportunities to expand your mind with new knowledge every single day. Oh, and we mean that very literally. Every. Single. Day. It’s something that the members of the massively popular ‘Today I Learned’ online community know perfectly well.

They share the new things about history, science, and the world that they’ve learned that day, and the facts are eye-opening, to say the least. We’ve collected some of their freshest new insights to share with you, dear Pandas. Scroll down and check them out. Don't forget your thinking caps!

We got in touch with Lisa McLendon, Ph.D., with a few questions about how the news is changing as our attention spans are getting shorter, as well as what can help motivate journalists to dig deeper and stay curious as they're covering stories. McLendon is the William Allen White Professor of Journalism and Mass Communications and the Bremner Editing Center Coordinator at the University of Kansas. Read on for Bored Panda's interview with her.

TIL a woman flying from Manchester to Florida had a heart attack during the flight and when the stewardess asked for help 15 cardiologists came to save her. They were flying to a cardiology conference.

Professor McLendon told us that the way that we consume the news, and how it's produced, is definitely changing.

"People consume news from a much broader variety of sources, on a much wider set of platforms. We are awash in information and we are used to seeing it in small chunks," she explained to Bored Panda.

Journalists and editors, in turn, are reacting to these changes in their audience's preferences. Some outlets, for instance, expand to social media platforms where they have to format things very differently. Brevity and engagement become more important than in-depth reporting. But that's not to say that the latter has lost its appeal!

TIL in 1947, the Canadian town of Snag, Yukon, saw a temperature of -83F (-64C). It was so cold, you could hear people speaking 4 miles away, along with other phenomena such as people's breath turning to powder and falling straight to the ground and river ice booming like gu shots.

"News outlets know this and have adapted headlines to catch people’s eyes and presentation to keep the audiences engaged. For example, if you look at how news is presented on a platform like Instagram, it’s presented visually in a short video or series of images so people can quickly get the main point. Most of these changes have happened to optimize speed and engagement, not depth," McLendon explained.

Meanwhile, we were also curious about what can help motivate someone who is completely new to journalism to delve deeper into the stories they cover, while researching and writing them up.

"Depth is crucial for certain types of news stories, ones that aren’t easily summarized in a quick-hit format but nonetheless have great impact on people’s lives. Questions and creativity can help journalists stay motivated to delve deeper on a longer, more time-consuming story," Professor McLendon, from the University of Kansas, explained.

"One way to stay motivated is to first find out all the ways something affects people, then anticipate their questions: What does this mean for your audience? How can you show them why they should care? What questions might they have that you can help answer?"

Something else that can help is to think about how you can present the information in the best possible way so that your audience understands the issues and stays engaged.

"Usually this is not one big, long block of text—it may include photos, videos, maps, graphics, even interactive elements like a quiz. Thinking creatively about how to present a story can help a reporter stay motivated," she shared some practical advice.

The r/todayilearned subreddit is almost synonymous with Reddit, the front page of the internet, by now. Created all the way back in late 2008, the ‘Today I Learned’ community has grown by massive leaps and bounds since then. At the time of writing, there were a jaw-dropping 30.6 million TIL members. The sub is living, breathing proof of how much the internet loves education that’s presented in an entertaining way (aka ‘edutainment’).

Here at Bored Panda, we’re fascinated with the TIL community’s desire to learn and share new things with everyone who’ll listen. When you’re done reading our newest post about their fascinating facts, consider checking out our earlier features about them here, here, and here.

Learning is far more than just getting good grades, being attentive in class, and doing everything that your teacher asks you to. True learning requires a lot of initiative and independence. It’s something that parents can encourage their kids to prioritize while growing up.

Recently, Bored Panda got in touch with Lenore Skenazy, the president of Let Grow, a nonprofit promoting childhood independence and resilience, and the founder of the Free-Range Kids movement. She explained to us that it’s becoming a problem that school keeps becoming a bigger part of kids’ lives. In the past, children had a lot more free time to do activities outside of school. 

“Kids goofed around, played, explored. Now, with jam-packed schedules filled with adult-run activities, even those out-of-school hours are a lot LIKE school… except instead of learning fractions kids are learning lacrosse, or chess,” Skenazy said.

#13

TIL Procrastination is not a result of laziness or poor time management. Scientific studies suggest procrastination is due to poor mood management.

“Clever, normal kids turned into caged animals who despair they are no good, and their lives pointless. The answer? It’s so simple and so overlooked: Kids need more free time and free play—exactly what you loved most as a kid. Time spent making up games, practicing free throws, jumping rope, poking around in the woods—all of that is not wasted time. It’s a time when all of a kid’s senses are engaged and growing: Observation, participation, empathy, curiosity,” the childhood independence expert shared with us.

“It’s hard to see when you’re swimming in it, but kids learn so much from life, from friends, from siblings, from doing things on their own that they can NOT learn from an adult, even the most loving parent or gifted teacher. Give them back some free time, during the school day and after, and they will start to blossom,” Skenazy explained to Bored Panda.

#16

TIL Fender Guitars did a study and found that 90% of new guitar players abandon playing within 1 year. The 10% that don't quit spend an average of $10,000 on hardware over their lifetime, buying 5-7 guitars and multiple amps.

Meanwhile, good grades aren’t the end-all, be-all indication that you’re doing well in life. “Quick! What was Einstein’s grade point average? How well did Dolly Parton score on her SATs? How many AP classes did Rachmaninoff take? Those questions are absurd. And so is the idea that a child is only as bright or talented as his grades and school performance,” Skenazy said.

“There are so many aspects to a person and yet so few are reflected in their report card. Creativity, kindness, a sense of humor, loyalty, wackiness—those aren’t measurable and so we forget they are even more valuable than an A+ on the spelling test.”

Raw IQ scores aren’t as strong an indicator of future success as many believe it is, but grades and doing well on school projects might just be. For instance, economist James Heckman’s found that someone’s IQ isn’t all that tightly correlated to how well you do financially when you’re all grown up. What’s far more important is your personality. Traits like diligence, perseverance, self-discipline, and conscientiousness are far more important than how smart you (think you) are.

You don’t get good grades just by having a high IQ score. You do so by having good study habits and being able to collaborate well with other students. In short, intelligence in the broad sense encompasses non-cognitive skills and traits which are far superior to scoring high on IQ tests. At least, as far as real-life success goes.
