Wikenigma is the wikipedia of unanswered questions and gaps in human knowledge for the curious-minded. For example, words of unknown origin, the dilemma of free will, or the purpose of the human chin. It's a jumping-off point for the imagination. — CD
“Principle Of Humanity: Every single person is exactly what you would be if you were them. This includes your political opponents. So instead of dismissing them as evil or stupid, maybe seek to understand the circumstances that led them to their conclusions.” Read 39 other useful concepts in this issue of The Prism. — MF
Here are a few of my favorite end-of-year lists, with two samples from each:
“Keep your identity small. ‘I’m not the kind of person who does things like that’ is not an explanation, it’s a trap. It prevents nerds from working out and men from dancing.“
“Cultivate compassion for those less intelligent than you. Many people, through no fault of their own, can’t handle forms, scammers, or complex situations. Be kind to them because the world is not.”
40 Ways to Let Go and Feel Less Pain
“Channel your discontent into an immediate positive action—make some calls about new job opportunities, or walk to the community center to volunteer.”
“Remind yourself these are your only three options: remove yourself from the situation, change it, or accept it. These acts create happiness; holding onto bitterness never does.”

The Museum of Failure is a collection of failed products and services from all over the world. It’s kind of weird, kind of sad, kind of funny. You can check out the collection here. — CD
The Manga Guide to Cryptography is a 190-page comic book that clearly explains the fundamentals of cryptography. You’ll learn about the foundations of encryption, symmetric-key algorithms, public-key encryption, practical applications of encryption, told in the form of a fun and engaging story. — MF
Wikipedia is so valuable to me that I have a mini version of it on my phone so I have access to it anywhere in the world anytime. I use Kiwix, a free app for iOS and Android, that parks a 13GB file with 6.6 million Wikipedia articles – without images. (The version with images is ). With Kiwix I can get Wikipedia on a boat, in the wilderness, or anywhere beyond cell service. You’ll want to download via wifi it cause it takes a long while. – KK
I’m learning a lot from scrolling through this list of common misconceptions. These are concise summaries that are linked to longer articles on Wikipedia. I like that they are worded as a correction, with the misconceptions implied. I’m relieved to dispel the misconception that the pyramids of Egypt were built by slave labor. I’ve also learned that dogs sweat mainly through their footpads and the Pacific Tree Frog is the only frog species that actually makes the “ribbit” sound. — CD
This stone ID app called Rock Identifier (Google Play, iOS) works fast in scanning and identifying rocks, minerals, and crystals. It’s got an extensive database so you can compare your stones to other images, as well as learn its chemical and physical properties, locality, uses, etc. I use it as an encyclopedia to learn more about how to identify minerals and how to tell real from fake crystals or gemstones. There’s a 7-day free trial, but for me it’s worth the $29.99 yearly subscription. — CD
I love poring over this gallery of physical visualizations. Each artifact is a representation of data from our history dating back to Mesopotamian Clay Tokens from 5500 BC. Some of them are so interesting and beautiful, like the brainwave weaving of dreamers, or this Yakima Time Ball meant to record major life events. Others are useful like this abacus ring from the Qing Dynasty, or mysterious, like South American Quipus. Maybe not useful, but really cool are these 3D-Printed Thoughts. There’s currently 370 artifacts listed — all of them equally captivating. — CD
By far the nerdiest food YouTube channel out there is Adam Ragusea with 2 million followers. He dives deep into the chemical nature of foods, such as what happens with smoking meat at the molecular level, why fennel and liquorice taste the same, or what is the chemical that makes the smell of rain. But also definitively answers many useful questions like “do the eggs of happy chickens taste better?” He references obscure scientific journals, does his own experiments, and mixes in delicious recipes you can follow yourself. He is one of the best science communicators working today. I recommend Ragusea’s food science playlist for the full course. — KK
If you spin this globe and zoom in you can learn the birthplaces of the most notable people in culture, science, sports, or leadership (from 3500BC-2018AD). Clicking on their names will take you to their Wikidata page where you can learn more about them. I learned about an indigenous princess who was born near my parents hometown in Mexico. — CD
It’s amazing how quickly my eyes got used to the detail captured by the new Webb telescope. You can compare the vast difference between the Hubble images of nebulas and galaxies and Webb’s new images on WebbCompare.com. Just slide back and forth and be amazed. — CD
As a Latina who grew up in California, anything I learned about my indigenous culture was by word of mouth or books I had to check out on my own. I’ve learned more scrolling through this visual essay of the Aztec Pantheon than I ever did in school. It’s a beautiful and colorful collection of 137 gods and their iconography. — CD
What came first: Watts Towers or The Beatles’ Abbey Road? The film Tom Jones or Eagles’ Their Greatest Hits? The Dream by Henri Rousseau or England’s Natural History Museum? This Google quiz asks questions like these (and shows relevant images) and challenges you to click what came first. A faster answer will yield a higher score. — MF
Before oil, empires fought over gold. And before gold, empires fought over spice. There were six spices that opened up the Americas, and bound Asia and Europe together permanently. Kate Humble, a BBC host, journeys to the remote geographical sources of these 6 spices in her series The Spice Trail. The depth of her research and travels are astounding. I am in awe of how ignorant I was about these substances, and now I am grateful how intimate with them her travels made possible. There are 3 sessions available on YouTube: 1) Pepper and Cinnamon. 2) Nutmeg and Cloves. 3) Saffron and Vanilla. History + Travel + Food. Highly recommended. — KK
Freelearninglist.org is a directory for finding the best education resources on the internet — including links and descriptions to free courses, YouTube explainer channels, podcasts, subreddits, effective thinking newsletters, how-to websites and more. Each listing is scored on effectiveness, design and popularity. It makes me want to never waste time on the internet with so many mind-enriching resources like this available. — CD
Being able to identify tree species is something I ache to learn, but I am intimidated by the amount research and reading involved. For now, I just enjoy noticing them and taking pictures of them. Also, I just discovered Monumental Trees, a website where people all over the world can submit their tree photos that you can filter by species and country. I still haven’t discovered all this site has to offer, but for now just looking at the photos satiates my curiosity! — CD
Tim Urban of the explainer site Wait By Why asked his Twitter followers “What’s your favorite mindblowing fact?” Sample replies:
The moon and the sun are exactly the same size as seen from Earth
Reno, Nevada is west of Los Angeles
Neutrinos, subatomic particles created in the sun, are so neutral and small and that a wall of lead a light-year thick has 50/50 chance of stopping one. About 100 trillion of them pass through your body every second.
There’s a giant volcano underneath Yellowstone National Park that would wipe out most life in North America if it were to explode (which it has done at least 3 times in the past that we know of).
Every tool that exists today, from hammers to particle accelerators, has been constructed with others tools, and those with other tools, and so on, and eventually all tools where fabricated with rocks.

It’s been more than three years since I deleted my Facebook account and lately, I find myself using Instagram and Twitter less and less. This list of 8 Ways Social Media Distorts Reality by the Center for Humane Technology reminded me why I have a 5-minute time limit on my Instagram and Twitter phone apps. I’m especially sensitive to “information flooding” and the algorithms are great at tricking me into thinking that everyone is talking about this one thing. As much as I do appreciate a community, I have to remind myself that Twitter and Instagram are not reality. The whole list is worth reading and understanding. — CD
The inventor Tim Hunkin released another season of his fantastic video tutorials introducing The Secret Life of Components, as in the motors, linkages, sensors and other parts you might use to build things. His hands-on knowledge is vast, and his BBC-perfected presentation skills are perfect for walking you through the plus and minuses of any part you ever might use. As fundamental as this information is, it is very hard to find, even on YouTube. — KK
