Not so. Anecdata point: My wife and I dropped our Delta Dental insurance this year. We reviewed what we'd paid in premiums over the prior 5 years vs. the full cost of procedures we'd had done in that time. Full cost would have bee

It seems there are RFID tags that provide sensing functions. I didn't do a deep dive, here's the first thing I found. [1] They sense temperature, pressure, and other parameters. I wouldn't be surprised if something like this

Health insurance in the US isn't 'decent'. Chronic illness, long-term care, catastrophic events excluded from coverage - these are real things that daily wreck American families. Of course one may be only a serious illness aw

In California, having your assets (home included) in a living trust shields those assets from Medicaid/Medical lookback forfeiture. [1] A living trust is a good idea for other reasons as well. [1] https://www.medicaidplann

And composite materials are basically threads embedded in glue. Threads can be extremely strong in tension. In compression, you have only the strength of the glue and the fiber/glue interface strength, which isn't a whole lot. Com

Experienced this in CA, so bad we really couldn't spend more than a few minutes outdoors. A good room air purifier and closed windows was a big help.

A fair cautionary statement. But the substack post (and presumably its analysis) is by Zach Rausch. As Haidt writes in the intro: >The rest of this post is Part 1 of Zach’s report, in his voice. Haidt hired Rausch as a research assistant

Second the recommendation Ben Rich's "Skunk Works" as a good read. A fascinating tale of hardware development in an earlier age.

It seems like this could be done differently, and perhaps more cost-effectively. Can't give cites right now, but here's a path I'd explore if I were in the field. I'd pattern the inner surface of the glass envelope with

This is excellent advice, and isn't restricted to the medical arena. Corporate counsel for insurance companies comprise one of the very few spots on the brontosaurus with low-latency innervation from the brain. Poke it, you'll usu

I've read various places that it's about 85% printed, by mass. The tanks & payload shroud, and portions of the engines as well. For the latter, the expansion nozzles and the crazy custom propellant plumbing were 3D printed.
