Disolation

Thanks! I got a new one later, but it's the regular (non-Decimo) kind, and it's my favourite pen right now.

I had my Vanishing Point Decimo stolen by a cleaner in my university.

I'm still upset about that.

If you want a good textbook, try David Morin's "Introduction to Classical Mechanics: With Problems and Solutions". Rather rigorous book with a good writing style and a lot of exercises.
