This book as the title may already show, is about a large number of “things” that you should know. Listing from Philosophy to Modern Technology. Both of which, and everything in between, are very much so a must have knowledge for anyone. Let alone a polymathic ULCian!
You can buy it for $15 on Amazon, or using their Kindle Unlimited it is free!
I’m sure you can find it on other sites as well, perhaps even at your local library.
I hope you enjoy the read!
