China is vast, nearly a continent to itself with highly diverse ethnic cultures. It has become an easy place to travel, with 28,000 miles (45,000 km) of high speed trains, and cheap domestic flights. My guide to traveling to the most interesting places in China is an English-speaking YouTuber, Yan, who calls herself Little Chinese Everywhere. Yan records her explorations of her own country, usually to offbeat, little-visited places, far from crowds, but extremely enjoyable. She specializes in the border areas of China where it mixes minority cultures (Tibetan, Mongolian, Uyghur, Vietnamese, etc.). Her channel is perfect armchair travel because she captures a very unromantic view of China, taking buses, renting motor scooter, staying at expensive hostels, interviewing shop keepers. This is the real China, and if you wanted to get a sense of what the everyday country is like, watch her channel. Better yet, visit it. — KK

Psychedelic readiness preparedness

If you’re considering psychedelic therapy, I recommend starting with Althea’s Psychedelic Preparedness Scale, a three-minute quiz that helps assess your readiness by evaluating mental health stability, intentions, knowledge, support systems, and coping skills. Developed in a clinical trial at University College London, the quiz identifies areas needing improvement to ensure a safer and more meaningful experience. Althea, a Public Benefit Corporation based in Oregon and Colorado, connects individuals with licensed facilitators for legal psychedelic therapy, aiming to make these transformative experiences more accessible and stigma-free. — CD

Netflix codes

I’m often very unimpressed with my Netflix algorithm, but these Netflix Codes have helped me discover new and surprising content. It’s useful, if you can overlook all the unsightly ads. — CD

Nuclear bomb rockets

One of the crazier projects funded by the US government was a plan in 1957 to build a 4,000-ton spaceship powered by exploding nuclear bombs. A small group of scientists aimed to reach Mars by 1965 in Project Orion, long before the dream of NASA’s Apollo. One of those working on the project was physicist Freeman Dyson. His son George Dyson interviewed his father and all remaining participants, and got thousands of declassified documents to tell the whole astounding story in a remarkable book, Project Orion. Published to little fanfare in 2002, Dyson has re-released a self-published expanded version (2025) with new material, new documents and illustrations, full citations of his sources, all material that the original publisher excluded. This strange story has lessons for attempting (and funding) hairy, audacious seemingly impossible projects. It’s great historical storytelling, too. – KK

Universal travel adapter with USB charging

The compact EPICKA Universal Travel Adapter has 5 USB ports (3 USB-C, 2 USB-A) and plug configurations for US/EU/UK/AUS. Its LED power indicator lets you know it's working. Just remember it's not a voltage converter — your devices need to be dual-voltage compatible. — MF
