It is a Wiki system with a LaTeX plugin so you can render equations.

In the nearby future we will post everything we solve from a textbook on the site.
The more students join us the more accurate it becomes. Also worked out versions of old exams can be submitted and found.

Every student can edit the solutions without registering, just like on Wikipedia.

I have no way of knowing if the problems I do for the homework help companies I work for are take-home exam problems. And even if it was clear that it is a take-home exam problem, there are plenty of online tutors who would help the student.

Was it really worth spending 2-3 hrs trying to solve a Jackson problem instead of doing other stuff? Well, you are not going to get it perfect and a get a 10/10 anyways. As Sunny says, it does help you understand the material more when you see the solutions (I also find it very satisfying to read through those elegant solutions once in a while). On the other hand, hw is a big part of one’s grade, so it can be unfair. How do you get around that? Do you want to make hw such a big part? Do you want completion of the problems rather than how they are worked? As a professor, will you have the time? There is no fair way of grading hws, it is just something that has to be done…

By the way, working in a group has the same effect; if one person solves a problem, it goes around to everybody. Is it fair to somebody who chooses to work alone and might not have gotten to the end but got there by himself/herself? Yet do we not envourage working in groups? Do we ask students to do the problems by themselves. If not getting help from online solutions and working through the problem should just be fine … as long as you understand the solution.

For that matter, for self-study, what does one do without available solutions?
There are a lot of us in this quandary!

Wow, I no longer can give you the benefit of the doubt; it’s clear that you do, in fact, have enormous contempt for your students (and your colleagues, too?). It also seems that that contempt extended to your not having read what I wrote.

When I speak of self-study, I am not talking about a homework assignment of three problems due tomorrow morning in class.

I am talking about the repeated working of problems that many students, undergraduate and graduates, do in order to prepare themselves for further work. This is more common with those planning to do a Ph. D. or with foreign students, many of whom are already equipped (as an earlier post noted) with solutions manuals for Griffiths, Jackson, Goldstein, etc. published in their own countries. (I strongly believe that most of the people accessing the online solutions will be foreign undergraduates, actually.)

In these cases, students may not have frequent access to a professor who can explain the problem step by step, may not have any access to a “Learning Center” (not sure what this means, unless you mean the tutoring offered for a few remedial students on some college campuses), and by spending their extra hours in working problems, surely must have already satisfied your criterion of not having given up after ten minutes.

As I said, I understand some of your frustration. I have taught students, ten-year-olds and undergraduates, and many of them have not learned that learning science and maths requires a good deal of work. Many of them have not learned any science or maths, period.

In any case, the point is moot. The textbook solutions exist and are available (and have been available for a long time to Chinese and Indian students), many students find them a valuable resource, and you will soon be sparing yourself the pain of having to deal with the untaught masses.
