The problem with the Casimir force is that it is difficult to measure experimentally and difficult to calculate theoretically. The research in the past several years has focused on expanding the class of geometries and materials that can be simulated in addition to devising more accurate experiments and methods of fabricating the nanoscale structures.

With Intravaia et. al's paper, they are dealing with a phenomenon that has been predicted theoretically, but has not been verified experimentally. The novelty here would be in being able to construct a periodic nanoscale grating and incorporating it into a measurement device. They also note a deviation in the theoretical force with their plates for large separations. It seems that this comes about due to their use of the Proximity Force Approximation as the kernel in their calculations. The disparate length scales that they are working with in terms of the object size, feature size, and separations are too much for current numerical methods.

Bennett Haselton's Response To That "Don't Talk to Cops" Video 871

Posted by samzenpus
from the to-talk-or-not-to-talk dept.
In response to both of my previous articles raising questions about the Fifth Amendment, people sent me a link to a famous video titled "Don't Talk To Cops" delivered by Regents University law professor James Duane. Whether his conclusion is correct or not, I think the argument is flawed in several ways. Please continue reading below to see what I think is wrong with his position.

There is a long tradition in the scientific community for the discussion and exchange of ideas that covers this. For example, the Royal Society was a group of people who got together to read their papers to one another as a group. The lectures were then collected and published to the world as a whole in the proceedings. Conferences are simply the modern day equivalent. In my field, conferences are a prime chance to bounce off your research to a large group of experts to get feedback and comments prior to publishing your work. Anyone can attend the conference as long as you show up and pay (but we all pay regardless). When submitting a paper to a journal, it is passed on to experts in the paper's field who provide feedback on the validity, results, method and prior work. Upon publishing a paper, a correspondence address is always included as well as the affiliation of the authors. People can write directly to the corresponding author or even write comments to the journal editor to be published in the near future (I've seen some rather negative rebuttals published in this fashion). There has always been a long tradition of exchange of ideas and thoughts amongst researchers, I've had people send me notes based upon my conference talks, journal papers, and preprints on arxiv. This isn't a closed network though. Anyone can attend the conferences, anyone can read the journal papers, anyone can write to the authors. Admittedly, the barrier to do this is rather high since access can be expensive.

The comments section on a popular science website is not the place for any real discourse, particularly with the authors. Researchers are under no obligation, nor do they have the copious free time, to shift through the chaff to answer all the questions and any serious discussion requires a lengthy back and forth for which a comment section is ill suited.

If you are interested in seeing more about how discourse is conducted in the research community, there are many collections of correspondences that have been published that gives an insight into just how much back and forth exists. I've read through a collection on letters on wave mechanics that you can get on Amazon for a small price that details correspondence between Einstein and other physicists. Many important ideas and inspirations in physics have evolved out of a passing comment in a postcard or daily walk.

They have done studies to see if "nurture" can lead to domestication but it simply doesn't. For example, they have taken wolf pups and raised them exclusively with humans as they would dogs (and they did the same for a group of puppies as control) and it was seen that the wolf pups did not demonstrate any domestication once they aged. I think that the silver foxes experiments have shown just how quickly domestication can occur. It only takes a few generations for domestication to really take root.

Australian Billionaire Plans To Build Titanic II 289

SchrodingerZ writes "Just in time to miss the 100-year anniversary of the fatal voyage of the Titanic, Australian mining billionaire Clive Palmer announced he has plans to recreate the Titanic, calling it Titanic II. 'It will be every bit as luxurious as the original Titanic but of course it will have state-of-the-art 21st Century technology and the latest navigation and safety systems,' says Palmer. He stated it was to be as close to the original as possible, with some modern adjustments. Its maiden voyage is set for 2016."
