This is a series of photos of WWII Polish resistance fighters who battled the Germans in a Warsaw ghetto for 27 days. On the left of each image is how they appeared in 1940. On the right are photos of the same surviving men and woman taken in 2021. Follow historyphotographed for the most fascinating photos from the past. — MF

Even if you’re not a copywriter, knowing the psychology of persuasive speech is helpful for everyone. We all write emails, and sometimes we have to sell people on ourselves or ask for something. Nick Kolenda created this 7-minute video on clever techniques in copywriting to boost sales. He explains how to replace vagueness with concrete examples, positive framing, and how to create mental imagery in the reader by adjusting the distance between words. It’s interesting and informative and I’ll probably rewatch it a few times. — CD

My new door mat greets guests with a cheery message. The natural fiber welcome mat says: YOU LOOK GOOD. Visitors enter with a smile on their face. — KK

Laundry Lens is an iPhone-only app that scans the inscrutable laundry care symbols on clothing tags and translates them into English. It’s free and doesn’t display ads. Here’s the result of my T-shirt label scan. — MF

My husband and I are planning to move out of California in 5 years and have been traveling to other states to check them out. We still haven’t agreed on a place, but I recently discovered this MoveMap which makes things easier. I filtered by my criteria: avoid drought, mountains within an hour, airport within two hours and a lot of sun. What I get back is select counties in Arizona and Colorado and most of Utah — as well as Santa Clara County, which is where I live now. — CD

I use this Baseten web page app to restore old family photos. The engine only focuses on faces, making them shaper and skin smoother, but sometimes that is all that is needed. I upload my old photo, restore in 15 seconds and then download. Works pretty well, sometimes perfectly, in color and black and white. Free. — KK

When I was 12 I built a chemistry lab in my basement and have been doing chemistry since. But I learned more about chemistry from reading this trio of books by Theodore Gray than anything ever learned in school. That’s surprising because these volumes appear to be photo books, full of pictures of metal chunks, high-speed shots of chemical reactions, and photos of everyday stuff. But woven through these unusual photographs are the best explanations of how and why chemistry works. The best looking of the three is The Elements, a hundred portraits of our universe’s true heroes; the most informative and fun for me is Reactions, which reveals why matter works. Advance onto Molecules if you like these. I read them all with wonder. — KK

The Small Fish Metal Brain Teasers set contains 6 bent metal puzzles. The challenge is to separate the interlocked pieces. One of ​​the puzzles is very easy to solve, making it a good starter challenge for a kid. The harder ones have resisted hours of my effort to solve them. The puzzles are made from heavy metal and won’t discolor your hands like cheaper bent wire puzzles. Comes with a cloth bag to hold them. — MF

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

WeCrashed is the 8-part mini-series on Apple TV about the astounding rise and subsequent crash of WeWork, the office sharing company. It’s heavily fictionalized, but nonetheless a gripping drama about the kind of magical belief that is needed to do something big. I was very sympathetic at the beginning. This roller coaster movie is well-done, very convincing, incredibly watchable and all the more compelling because the protagonist, Adam Neumann, is back this week in real life with an even bigger scheme, which another billionaire funded for $350 million at day one. Watch this series to see where the real season 2 might go. — KK

You can be creative and destroy less books by using this web app Blackout Poetry Maker created by Emma Winston. You can choose from 3 sample texts or copy and paste your own custom text. I used excerpts from my diary and created this poem I call “All the unknowns are outlined.” — CD

I have paid subscriptions to the New York Times, Washington Post, Wall Street Journal, Medium, and others. Some of the publications let you share individual stories to friends who don’t have subscriptions, but some have strict paywalls. When I want to share a paywalled article, I paste the URL into Archive Today. It creates a snapshot of the article and generates a shareable URL. — MF

One of my favorite newsletters is TITAA (Things I Think Are Awesome) by Lynn Cherny, a data scientist consultant who sends out a monthly roundup of whatever she finds interesting in the fields of creative AI, generative art, science fiction, fantasy, games, folklore, poetry and more. It’s weirdly fascinating and always inspiring. Here is a link to the archive. — CD

A swell account I follow on Twitter is Massimo. They consistently posts the most interesting science-y, curious, and educational stuff. (And no outrage!) It bills itself as “Astronomy, astronautics, meteorology, physics. Engineer, trying to build the big picture of #science via selected & curated pics, videos & links,” which it does spectacularly well. — KK

Dru Riley has put together a list of 100 useful rules for making life more rewarding. — MF

Samples:

• “Read and listen to whatever you’re most interested in.” — We get more out of what interests us. Find something that you enjoy reading instead of struggling through books.

• “IDK = No” — If you’re uncertain, the answer should probably be no.

• “Don’t make them think.” — Make it obvious.

• “Price affects risk.” — If an experiment is cheap, just do it. The more the price goes up, the more you should reconsider.

Hardly anyone makes luggage without wheels now. But for some crazy reason, most toilet plunger don’t have T-shape handles. The T-shape top allows you to plunge sinks and toilets with greater force and control. Do yourself (and your wrists) a favor, get a plunger like the Korky Telescoping T-Shaped Handle BeehiveMAX Universal Plunger. — MF

I learned some valuable techniques and got a lot of wise guidance for cultivating a happy family from the book The Secrets of Happy Families (2013). Much of it I wished I had known earlier when our family was younger. There’s a bunch of self-improvement advice out there, but not much on family-improvement, so this is highly recommended. — KK

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
