For some reason, this vexer (really, this is a typical problem right out of the texts of a 1st year Intro Physics course) appears to be a real stumper. We had...

OK, we have a few "fertile" minds around here <pun intended>. Last time I asked the following: **************************** "A sultan tried to increase the...
For this week's vexer, the number of credits you get for the correct answer depends on how many you found. Take note that you can submit as many answers as you...

Ooooookay. Obviously, long-winded answers to a vexer is NOT popular. <makes a mental note> I decided to simply award the # of points for answers even remotely ...
This one should be really easy. A telephone call interrupts a man after he has dealt about half of the cards in a bridge game. When he returns to the table, no...
This is a followup to Message #189 which reported such measurement up to 100 micrometers. In the continuing effort to check and refine the range of values ...

OK people, the vexer can't get any easier than this, so if you have been shy at trying one of these things, this is your opportunity to get into the fun! The...
Welcome to all the new members during the month of April. We look forward to your participation here. Any legitimate physics discussion and/or questions are...

This paper from Rep. Prog. Phys. will be accessible for FREE only for a limited amount of time (I'm guessing till May 15th or so). So if you want it, go to the...
It was good timing (on my part) to put up pictures of an apparatus involved in the measurement of angle-resolved photoemission spectroscopy (ARPES) in our...
Interesting. We roughly had half of the answers submitted being wrong. Last time I asked the following: ... to ... spring ... which ... set ... can ... the ......
This week's vexer is challenging, but once you figure out the solution, the explanation is rather straight-forward. One of the things I like the most about...
This was reported about a year ago, and the lead author of the study has written an essay in the May issue of Physics Today. It shows how bad the physics texts...
OK. Just to show you that you get very timely reporting on here regarding the "hot" news in physics, I reported these two experimental results on April 22nd....
