Experimental nuclear and particle physicist. These days I'm teaching, but I've spent a lot of time on nucleon structure in fixed target electron scattering and neutrino oscillations using reactors and beam sources.

Been reading Zemansky & Dittman's book on thermodynamics recently. Quote: ``The concept of temperature is rich in interpretations and levels of abstraction.'' Nice.

In the (Unix) X world this would be called "pinning" the window. Not sure if this will help in searching.

comment Revisiting the creation of a new site: Physics Learners
Well, the reason---as I understand it---for wanting that site is because here on Physics SE we insist that basic questions be framed in a way that is both difficult and awkward for students who just want help with their homework. But then I'm another person who wouldn't look at a site for that purpose: I do enough of that during office hours.

comment Is there a significant possibility of the LHC missing "exotic" particles or events?
@AcidJazz In addition to CouriousOnes comments, consideration of what should be in the triggers, how to structure the triggering decisions and how many minimum- and no-bias events should be taken is subject to on-going consideration. moreover, parts of the trigger system run on FPGAs so substantial changes of kind are possible. The system in use these days are mindbogglingly flexible compared to the ones I leaned on less than two decades ago.

comment With the LHC about to restart as max energy, are there absolutely no hints or tantalizing signs of Supersymmetry in previous data?
@Curious Ah ... I didn't to suggest looking to Fermilab for evidence; only that "absolutely no hints [...] in previous data" isn't really applicable to the low-energy LHC data as yet.

comment With the LHC about to restart as max energy, are there absolutely no hints or tantalizing signs of Supersymmetry in previous data?
@Curious Certainly they'll still working on that data because they aren't part on a LHC experiment, but they are still getting new things from it. The depth of the data from these big experiments and the analytic cleverness of the physicist who run them is staggering and too easily underestimated.

comment Why is a beam reach the fastest point of sail on modern sailboats?
Back when I was learning sailing they told me the broad reaches were a bit faster than beam. But in any case, the question of why reaches (in general) are fast on sloops is a good one.

comment True randomness?
Hmmm ... on further reading I see that you are trying to draw a strong denotative difference in the works "random" and "probabilistic". I see where you're coming from on that, but I don't believe that this distinction is universally recognized.

comment True randomness?
This bit "those processes are not random from a QM point of view. Simply QM introduces, as I said, the concept of probability of a measure as opposed to exact knowledge." is interpretive and not backed up by clear experimental data. The data tell us that it is either actually random or practically random because we can't know the hidden variables, but it doesn't distinguish the two cases. You can have either a local truly random theory or a non-local hidden-variables theory. You just can't have a local hidden-variable theory.

Be aware that CDF and D0 are still analyzing their data years after the Tevetron shut down, taken apart and bits of it chopped up and put on display in the lobby of the highrise. "Absolutely no hints of [...] in the data" is too high a standard to expect for the 3.5 and 4 TeV data for another decade or more.

comment Can we have more close votes?
Hmmm ... Stack Overflow went through a period with the closevotes available to active closers weren't sufficient to keep up with the poor (or poorly formed) questions. In a sense it could be seen as a positive sign about our growth, but we can certainly ask the team if we should be treated as a "bigger" site these days.

comment How can I view the breakdown of votes on an answer versus the simple total?
Forced comment suggestions in many, many variants have been uniformly and firmly shot down on the mother meta. Everyone gets an annoying drive-by down votes from time to time, but they are here to stay.

comment Programming in physics
The real difficulty with this is that there are no wrong answers here. No right answers either given that what is true in my bit of physics in doubtless wrong in some other corner of the discipline. Short versions: there is no preparatory curriculum of "physics programing", because there is no single notion of programming in physics. Not for software, not for language, not for hardware (which changes ever ten years or so, anyway).

comment Sonoluminescence spectrum
For that matter, is the spectrum thermal in the first place? Can you find the (some) temperature from it? My suspicion is that it is not (insufficient time, after all) but I don't know.

comment Action-Reaction pair in case of rocket accelerating in space
Don't let the names "action" and "reaction" that Newton used fool you. The two are simultaneous in time and there is no implication that one must be active and the other passive. There is neither a point nor a need to sort out which one is the "action". You just need to identify the pair.

"Please be honest and direct in your reviews." I suspect that what has been frustrating you is that people have been being honest and direct in their interactions with you.
