An evening pause: A little dense for non-engineers, but just clear enough to be educational for all.
Hat tip Edward Thelen.
As always, I am in need of suggestions for evening pauses. If you’ve seen something you think will fit, place a comment here, in this post, but don’t post a link to your suggestions. I will contact you so that you can send it to me direct and I can then schedule it.
