I rely on other people for a lot of this, I’m not exactly going out and doing a whole bunch of original research on things like human evolution (hard to experiment much on that without some pretty severe ethics violations…), cephalopods (I’m not near any oceans), and so on.
So, I rely on a lot of other people to do all of this.
I’m going to comment on a few sources that I often like to go to. This will be an ongoing post, updated whenever I get around to it or discover a new source or whatever. Feel free to comment with sources you’d like me to review/describe/rate.
General information
Wikipedia. Good ol’ Wikipedia. It is… more accurate than a lot of people think, and can be a good source for basic information. You have to beware of vandals, people with specific agendas, and so on, and sometimes the content is…not presented in the most user-friendly way (eg on relatively “niche” science topics, the articles sometimes get deep into science speak that can be hard to follow if you don’t have expertise in that particular area), but it’s great for basic “Hey, what/who/how is That?” type questions.
General science information videos
Scishow, and its various subchanels. Informative, interesting, well presented, mostly short videos about a wide variety of scientific topics, from big ones like supernovas and the Earth’s magnetic field to small ones like why we itch the way we do, or why it’s hard to swat a fly. They generally manage the sometimes delicate balance of explaining a topic to scientific novices without either boring or insulting people who do have a science background. And while I’m not claiming that they have never made a mistake (I wrote a How to Science article about being Less Wrong), they seem to be pretty accurate.
It’s OK To Be Smart. Again, well presented, accurate (as far as I can tell), and explains the intricacies of complex topics without making you feel like an idiot. Not quite as wide-ranging as SciShow, but this channel only has the one presenter, instead of the team that SciShow has.
Minute Earth. Their videos tend to be shorter and more directly humorous than SciShow, with cartoon animations to illustrate relevant points, but have a similar variety of topics, and a good balance between explaining things to the uninitiated and not making you feel like an idiot. They also have some sub-channels, like Minute Physics and Minute Food
Kurzgesagt. They seem adequately factual and explanatory, though there’s something I just don’t quite like as much about their tone. It seems a little… condescending, I guess. Their videos use animation, usually involving ducks, to illustrate their points.
Stated Clearly. A slightly oversimplified, but clear series of videos, with a single presenter, that is using mostly analogies, animations, and the like to explain complicated or controversial scientific topics, mostly but not all related to evolution.
More specific science or science-adjacent videos
Forrest Valkai, and particularly his Reacteria series. Reacteria is an involved debunking of bad creationist videos. His other stuff includes things like reviews of science kits for kids.
Bizarre Beasts. A deep dive into various unusual animals, what makes them unusual or unique, and how they got that way or what function the strange trait serves for them.
Lindsay Nikole. She does informative (if somewhat sweary) zoology videos, as well as somewhat silly (though also informative) short-form videos.
True Facts. Extraordinarily silly videos about assorted animals that are, nonetheless, still well researched (including listed sources) and (except for the obvious jokes) pretty factually accurate.
Alien Ocean. Someone who calls herself “The Octopus Lady”, who does somewhat humorous deep-dive videos on assorted marine organisms. She uses a mixture of simple animation and actual pictures or videos of the organisms.
Doctor Mike. Does many mostly humorous, but factual videos on assorted medical topics. Meme reviews, reviews of “health hack” videos, reviews of the scientific accuracy of medical scenes in movies or TV shows (even cartoons, according to him “Doc McStuffins is surprisingly accurate, at least for a kid’s cartoon)
Mama Doctor Jones is fairly similar, except that she exclusively focuses on matters related to obstetrics and gynecology.
Adam Ragusea is mostly a cooking channel, but he does dive pretty regularly into the science of food, even doing things like experiments to figure out what makes the shiny skin on top of brownies, or how mixing a meringue affects the resulting foam.
Because Science is a channel with a guy who looks a lot like Thor doing deep-dive explanations of the physics, biology, etc of (mostly) various pop culture things–firing the Death Star, “The Snap” killing Iron Man, and so on. It’s thorough and engaging, if sometimes a tad on the silly side.
