There's a company now called SwissMicros that specializes in releasing old HP calcs with modern hardware. Their flagship is the HP-42. Basically it uses the original HP operating system (thank you HP for releasing it) but it has an utterly gorgeous display and HW in general. You can see the entire stack at once, it's gorgeous with a digital ink display.
I have a couple HP-48GX as well, though I'm experimenting with the HP Prime now. Awesome calc but the RPN programming support is meh.
Just read it. You have to suffer through 2/3 of the first book about the Chinese cultural revolution but shit gets real after that. And by the time you hit the chapter The Singer in the third book you've gone off the deep end and you'll never see the universe the same again.
Moral of the story...it's a bad idea to telegraph your presence to the universe at large.
I'm obsessed with astrophysics. The universe is so impossibly huge and complex it drives me crazy. You ever read Tau Zero? A somewhat lame 70s sci Fi book but it addresses the exact relativity you bring up.
And the greatest books I've ever read are the Three Body Problem trilogy. Utterly life changing.
I'm just learning it myself so I can be more informed about the weather and maybe even a better poster someday. The math itself isn't so hard, you just need to remember all the constants. There aren't any imaginary numbers or anything so it's all pretty intuitive. Just gotta put in the work. Two years ago I taught myself basic astrophysics via a couple textbooks...now that was esoteric. It's hard to get excited about something so abstract as the universe though so I'm more interested in weather. Learning about relativity really doesn't have an impact on your daily life, but gravity waves....
Bruh, real engineers use HPs and RPN.
Luckily my watch has a slide rule built in for those times I'm without my trusty HP. It's surprising how often I use it for basic multiplication and division.
Haha, I struggled through calc 1 and then something clicked and I got 100%+ in calc 2, calc 3, diff equations, and linear algebra. Doesn't mean I know anything about weather but I can math with the best of 'em.
Hey I'm learning about gravity waves in my atmospheric climate textbook. I think there was some discussion on them earlier this winter. So much math in weather, I never knew! Lots of fun for an EE major and applied mathematics minor.
Very light snow here, no accumulation, not even on my deck. But it looks nice and is a good end of winter event so I won't complain. It also gives me an excuse to run the wood stove.
I asked my wife what she thought and she said that happiness equals reality minus expectations. And then she told me to leave her alone and stop wasting her time.
Thanks man, was secretly contemplating what it would take to convince my wife to drive back up tomorrow and pitch a tent for the storm and camp out there....
Closed on the mountain property yesterday (no hillbillies were harmed). Winter storm watch for 6-12" currently. Too bad I'm back in SoMD under threat of heavy cloud cover.
So is winter still over? Just wired the money over for my Garrett county mountain. So I'll be ready for next winter. In the meantime it's time to de-winterize the Ducati and get ready for spring.
Lol, I don't have that acreage yet. I'm impressed you remembered. Closing is on 3/9. I did sell a whole bunch of stocks so I'm ready to roll. It's just under 200ac.
I was born in Detroit and lived in Michigan for 24yrs. Frankly by March I'm ready for warm weather so this recent trend of cold springs can eat a dick. I have a good story about trying to maneuver a GSXR1100 in the snow in Michigan in May. No thanks, been there, done that.
