# Josh's physics picks: September 13, 2015

Each week, I'll be choosing four or five of the most fun and interesting problems (in my opinion) I see in the community and posting them in a set. I'll be keeping an eye on the solutions, and at the end of the week will do a writeup on those I find exemplary. I'll also point out interesting things about the topics and where possible, show how to extend the thinking to more general situations.

Here is the first set

I hope you enjoy my selections and get something out of working on them. I'm looking forward to seeing everyone's work.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
• Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Hey Sam, the picture is from the cover of "Einstein Gravity in a Nutshell" by Anthon Zee. I don't know who the artist is, but that's where I saw it.
