Thus, an understanding of classical mechanics will open many doors in science and engineering. Most students describe Physics 451 as a demanding and challenging course. Mastery of the material requires patient study and mature use of mathematics. It is encouraged that you also tackle some interesting problems using powerful 20th-century mathematical tools, such as Mathcad, to perform numerical analysis and help us visualize the mechanics we study. Scientists and engineers normally work in small groups, and social interactions are critical to their work.
Most good ideas grow out of discussions with colleagues.
Study together, ask each other questions, help your classmates get over confusions, and critique each others homework. Teachers find that they understand a subject much better after teaching the course, and you too can learn a great deal by teaching one another. Therefore, for the homework exercises and problem sets, you may work with anyone and use any published or unpublished sources. Of course, just as scientists and engineers cite the contributions of others in their papers, I expect you to list your sources of help and the extent of that help on the homework problems you turn in for grading. Furthermore, regardless of the help you receive on problem solutions, I expect you to fully understand the work you turn in.
