can you suggest a book which teaches fundamentals and basis of fuandamental of mathematics

Although i do understand how current is same in electrical components in series.. but why does the voltage remain constant in parallel? Also since voltage remains constant in parallel, is that the reason change in voltage is generally chosen as the signal in digital circuits?

I'm currently in the first of my introductory physics course - PHYS 2425: Mechanics and Heat. This is the book we're using. Is it a good intro. textbook? Thanks. Fundamentals of Physics Extended, 8th Edition David Halliday, Robert Resnick, Jearl Walker...

Hopefully I am posting in the correct forum, but was reading through Cahill's 'Physics 12 for Western Australia' (2nd Edition) and reached chapter 3, regarding magnets and electricity. There was one paragraph which confused me, and seeing as the school year has not started yet, there is no...

To begin with, I'll let you know I am a student. I am prone to theoretical physics and philosophy over cold, hard, mathematical fact. That being said, I was recently intrigued by a few things I learned regarding the Big Bang Theory. I'm still really shaky on the topic, though, and I could use...

What are the fundamentals in today's science, is the Higgs field fundamental, in cosmology is the Metric fundamental?

I was reading my text and doing some problems and I realize that I am having a lot of issues understanding some of the basic stuff :( I have a few questions about charge, fields etc. Like given the charge on an object after charge has been transferred by rubbing, how do you tell how many...
