As expected, there weren't many correct answer for this one. From the initial setup, one can already see that the problem is an elastic one, where all other...
This puzzle should be familiar to the regulars of our undernet physics channel since a similar one has been asked before. Again, please read the Vexer rules...
There is a series of article in the latest issue of Physics World regarding what people think as being the "most beautiful" experiment. Most seem to have...
Hey Zaps, Being a physicist in the field, what do YOU think is the most beautiful of experiments? As an undergraduate I haven't had the opportunity to truly...
... Humm... good question. I haven't actually haven't given much thought on my personal opinion on this matter (shock!). So off hand, I'd go along with the...
I have uploaded a link to Vic Stenger's preprint on this topic in our Links Section (Physics Papers and Preprints). This is a good overview on the nature of...
Another to a paper from the Proceeding of the National Academy of Science has been uploaded to our Links Section (Physics Papers and Preprint). This time it is...
Considering that a similar problem such as this was already discussed a while back in our IRC channel, I found it surprising that we didn't have more...
This week's vexer should be easy, but PAY ATTENTION to making sure you describe a CLEAR and unambiguous method, because again, you only have ONE attempt at...
I have uploaded a link to Eugene Wigner's very famous essay on the connection between Mathematics and Physics. This is one of those essays that have grown into...
No matter how much you love doing something, the practical reality is that one eventually HAS to make living. Being a physicist, or a physics major would not...

Unfortunately, no one answered the question from our last week's vexer completely. ... the ... Label the bars as A and B. Now take iron bar A and touch it to...
John Bahcall of Princton's Institute for Advanced Study presented a talk here at Argonne lab on Sept 12 titled "Why the sun shines". It covers the history of...
Any regulars in our Undernet Physics channel would have come across my "ramblings" that in college Intro physics, ALL that the students will learn are nothing...
This week's vexer should be another simple one. So don't be shy to try it! I was asked this puzzle by one of my young nieces (she was maybe 7 or 8 years old...
In the never-ending quest to gather valuable links for our website, I have uploaded another link to an online physics text. This time it is a link to a...
When I used to teach undergraduate Intro Physics course a few years ago, I asked this question on the first day of the semester to the students. Most were...

Not bad! As expected, last week's vexer was a "cute" little test of Newton's 3rd Law of motion. The problem with my niece's solution was that whenever the...
This week's vexer is easier than you think. And that's all the hint I will give! :) If you are standing at the equator at sunrise, where must you point a laser...
Looks like last week's vexer proved tougher than it appears. To remind everyone, here's the vexer once more: "If you are standing at the equator at sunrise,...
The prominent physicist Harry Lipkin was in town (at Argonne) last week, and I had a pleasent conversation with him (or more that he was the one who was...
