Sometimes yes, sometimes no, but even when confident there can be a mistake sometimes:)

Sorry, seems like I sorted out the problem:)

I'm self-studying various physics topics (as a hobby) and currently enjoying "A first course in general relativity" by Schutz. I also have the students manual for this book by Scott which provides the answers to a selection of the exercises in the book as well as some additional material. For...

Thanks!

Thanks, that helps a lot! It's indeed easier to understand when thinking of redshift as how much the universe expanded during the photon's travel. I Googled a bit to fully understand the formulas you gave and read the bit under "evidence for acceleration" at...

I have read several articles about this topic, on Wikipedia but for example also this article http://supernova.lbl.gov/PDFs/PhysicsTodayArticle.pdf and also several books that discuss the subject. In very brief my understanding is that: - 1. When observing type 1a supernovae (standard candle) at...

Welcome! No, I'm not an engineer graduate, actually I have a degree in Marketing but I want to study physics now which means I need to understand the math too :) My level of math knowledge was quite limited before I started, which is one of the reasons I chose Stroud, as especially the first...

I have now ordered "Special Relativity: An Introduction with 200 Problems and Solutions Hardcover" by Michael Tsamparlis. I think this will have more complete solutions so I will try my luck with these but further suggestions are still more than welcome.

I have myself worked through Engineering Mathematics (Stroud) and I'm half-way through Advanced Engineering Mathematics (Stroud). These two books cover many of the things you mention above and the author explains the concepts in a very straightforward way, no prior knowledge on the topics is needed.

I totally understand what you are saying. However, I have limited time so I want to spend it as efficient as possible. I have a full-time job and manage to study physics/math for about 10-16 hours a week. Also, I have always studied in the way I suggested: first trying to figure out things by...

Anyone with a further idea on this? Still hoping to find a solution manual or another form of answers that include workings. Thanks!

Thanks for the suggestion, that is definitely also an option but as you say indeed slows one down, I find that often from a correct solution that includes some steps it's very easy to understand how it's done, for cases where I would still not get it for whatever reason (for example if I...

I'm currently reading Special Relativity, the famous book on this subject by French. The book does contain a nice set of problems for each chapter and corresponding answers at the end of the book. The issue I have with the answers though is that they are mostly just the correct answers, there...

Anyone that can help? Still hoping for an answer:) Thanks!

Thanks a lot for the further input and explanation. That helps but I still don't understand how they arrive at the value for t at event E. Can you show me how that should follow from your reasoning above?
