  • I’ll go down this rabbit hole for you because I was also curious.

    All lead mined on Earth naturally contains some amount of the radioactive element uranium 235, which decays, over time, into another radioactive element, a version of lead called lead 210. When lead ore is first processed, it is purified and most of the uranium is removed. Whatever lead 210 is already present begins to break down, with half of it decaying on average every 22 years. In Roman lead almost all of the lead 210 has already decayed, whereas in lead mined today, it is just beginning to decay. (Of course, many lead 210 atoms have already decayed in this ore, too, but the supply is constantly replenished by uranium in unprocessed lead). “The longer since it was originally processed, the lower its intrinsic radioactivity,” Gonzalez-Zalba says.





  • I think people interpreted my comment differently than I expected. Most people are Linux users because they like tinkering with their computer. That takes time. Getting all your devices/accessories/accounts working on Linux that used to work on other OSes takes time because they probably don’t have 1st party support. Otherwise you can use Android or Apple or whatever and just take what you get with less tinkering.

    I’ve been using the same pro Windows license that I got for free in college and have never paid Microsoft a dime. I don’t know of any forced subscription fees. Paying for more cloud storage, etc. is a shitty practice but certainly not unique to MS.
