I would like to personally welcome all the new members that joined us within the past 2 weeks. Hopefully, you'll find something useful in this group in...
If you're at all interested in particle physics, there is an interesting series of articles to be found at kuro5hin.org, written by a PhD student at Simon...
I have put a link in our Bookmarks - Online Physics Lesson section - to a site containing supplimentary materials to accompany the E&M text "Electromagnetism"...
When a rock falls down into a deep well, it takes 2,6 s before you can hear the "plop". (i) How deep is the well? (ii) Is it necessary to take notice of the...

... me too,well 30.79 (rounding errors), and ignoring the speed of sound it's 33.12, I dunno about how much an aquafir(sp) varies, but I guess that is not as...
In most universities in the US, a student must have a declared major by the end of his or her second year. So this is an important transition - making the...
...cont. Knowledge of computers is almost a "given" nowadays. However, in physics, this goes a step further. No matter which area of physics you intend to go...
Chalk this up to excellent timing. Right after the last installment of "So You Want to be a Physicist" series, along came this paper on the e-print archive...
Several weeks ago, I posted a comment and a link regarding the validity of the idea that we can have a "Theory of Everything". As Bob Lauglin pointed out in...
This is a rather interesting paper that is being submitted to the American Journal of Physics. It reveals a research done to study how students understand the...
Enter your vote today! A new poll has been created for the undernetphysics group: Who are you? o A practicing physicist o A non-physicist with a physics...

On the night of the 12th August, the three principal maxima of the Perseid meteor shower are predicted to occur. As the name suggests, the radiant (the point...
Hi, I was a physics major but I am not a practising physicist. I did a year of research (under the honors program). I got my degree but regret ending my formal...
Beginning this weekend (the weekend of Aug. 10 and 11), we will have a weekly puzzle quiz which I am calling the VEXERS. These will be puzzles of varying...
Ok, everyone! Here is our innaugural vexer! Remember, you only have ONE attempt at answering this vexer, so make it count. And make sure you send in your...
Although our first vexer was somewhere ruined by an inadvertent posting of an answer to the whole group, I would like to remind all of you that there's MORE...
One of my pet peeves with all the quackeries about perpetual motion and endless supply of energy is that most of the people claiming to have invented those...
Ok, it didn't go too well. Our first vexer was either too easy that almost everyone didn't feel that it was worth the effort, or the whole concept isn't as...
This week's vexer is again, another simple one. This is one of those "familar" questions that you come across often. Again, as a reminder, please read the...
Er.... people, this is a SIMPLE vexer, honest! The question is asking what happened to the water level before and after you dropped the cannonball, i.e. (1)...
Since there are many people who keep coming up with questions regarding Strings, Superstrings, etc. in our channel and somehow have the impression that they...
Don't forget. If you haven't taken our poll yet, please do so. It's fun, and it costs none. To take part in the poll, click on the Polls link in the menu on...
It appears that the Yahoo e-Groups have changed our menu slightly. Our "Bookmarks" section has been renamed as "Links". All the links within that section...
It was, to say the least, a very interesting week with regards to the vexer. I honestly thought this was a simple one (but then again, what do I know?). First...
After the last two vexer, I have no idea anymore if this is an easy or difficult one. So we shall see. As always, please make sure you have understood the...
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...
