Perfect!!!

I am a physics enthusiast at best, this app is perfect for an entry level science nerd as myself. Most sources are vague and minimal, this app is extremely extensive and allows you to quickly search for your topic or you can select for it to pick a random topic for you. I agree, you can spend a lot of time making notes and searching for topics for free... or pay the two dollars to have it all wrapped in a bow and ready to go! Thank you for this app!!!
