The study of unidentified aerial phenomena (UFOs) and the acknowledgement of the extraterrestrial hypothesis (or extra dimensional) will become mainstream. https://www.gillibrand.senate.gov/news/press/release/gillibr... Soft disclosure has happened already via the USS Nimitz encounter. If UAPs are true, then the floodgates are open and will lead to a forced re-evaluation of other high strangeness phenomena (telepathy…

I always found it strange how UFOs concentrate in the U.S,is it because of the climate? /s

I wanted to believe and there is a serious subreddit for UFOs but most are debunked. There exist ~2 truly mysterious UFOs and most of their mystery has been explained.

I'm going to go a bit random...get a styptic pencil!

Nobody I've met even knows what they are. I came across them years ago in the shaving section, and was blown away by their utility.

They are solid pieces of some saltlike material that are super effective at stopping bleeding. We don't even have bandaids in our house anymore, the pencils are way more useful.

Quantitative easing (sometimes mistaking called "money printing") isn't directly inflationary. Because when central banks buy bonds, they do not pay with normal money. Instead, they pay with a special type of money that can never enter the real economy (as to not create inflation). This special type of money are called "bank reserves". And bank reserves can only be used to 1) settle interbank transfers and 2) buy mor…

If the loop is closed then this money has no use, it is not money. If it's not closed it cause inflation. It's binary. How can you instead define a spectrum of cross talk between real money and sandboxed money?

Consider arm sized, hand sized, fingernail sized, and pinched-fingers "tiny" sized. About 1000, 100, 10, 1 mm. Tray of cookies, hand-sized cookie, chocolate chip, and tiny crumb - yum. Now zoom 1000x, taking tiny sized to arm sized, and they become 1000, 100, 10, 1 um. Call this microview, with microscopic microorganisms measured in micrometers. A grain of salt is sized like a cardboard box, a head hair like a hand-s…

Feels like a good VR experience or magic school bus episode would help solidify this! Or maybe time for this adult to make some dioramas.

I've owned both, and found 'alum blocks' pretty useless. Looking up the ingredients, they seem very similar however. Maybe the pencils are more concentrated? They are solid white and chalky, not semi translucent and slick like the alum block I bought.

Reptiles (and other ectothermal vertebrates) will “artificially” give themselves fevers by staying in heat sources longer when they’re fighting an infection. It’s called a behavioral fever. https://pubmed.ncbi.nlm.nih.gov/27381718/

I've definitely felt this before, The hot soup, hot tea, sweatpants, sweatshirt, wool hat, get-in-bed I feel like I'm about to have a fever reflex.
