Using technology in Physics Currently I find that technology is a wonderful tool in efficiently understanding physics. It helps in giving access to resources and providing a better understanding of topics but what I dislike is slowly figuring out that this resource “could have changed everything” I’ve been doing till now because it was “a secret that only few knew of “. 
So I wanted some secrets others have been using for long which they're sure will help others as well. I'm looking for things such as online-simulators, physics 'news' websites, chat forums etc. 
What aspects of technology (or for that matter-resources in general) have you been using that have enabled you to become better at understanding physics?
 A: Mandatory listing, I guess:-


*

*https://arxiv.org/archive/physics

*https://www.researchgate.net/
I’ll update if anything better comes over time. 
A: As a response to what I wish to focus on, here are the things I find helpful in my learning of Physics:-


*

*Physics StackExchange

*r/Physics-Fun physics to explore on reddit.com

*quantumdiaries.org-To keep up to date with physics (I need something better to replace this).

*The various chat forums on the Art of Problem Solving(AoPS)-To discuss, a bit more freely, various problems and questions regarding physics/science.

*MIT OCW/edX lectures

*Online youtube resources (from Walter Lewin to MinutePhysics to Veritasium).

*COURSERA courses (which I'll admit I haven't used as much).


I figured I might as well go personal so here's a little something extra:-


*

*I have pdf's of books which I review before buying (if ever). These pdfs are from other online resources but a specific resource would be the Telegram communication app where 'channels' send multiple pdfs of various books. This is extremely helpful to use before buying a book.
