Of Particular Significance

Category: Housekeeping

The rate of my blog posts has fallen off again, but for good reason… change is in the air.  I decided this past year to leave Rutgers University, after a six-year stint as a professor at their “New” High Energy Theory Center, or NHETC.  [No one ever deletes “new” from a name, cf. Pont Neuf. Corollary: avoid putting “new” in an institution’s title.]  Starting in September, I’ll be a Visiting Scholar at Harvard University. For scale, the distance from Rutgers to Harvard is about the distance from London to Paris.

Needless to say, there are some logistical issues involved in this change! So this is a busy August. In fact this is my third shortened summer in a row. (The previous one was curtailed by a certain dramatic discovery…) So that has reduced my blogging time considerably.

Next week is equally busy — but it will generate some blog posts instead of completely inhibiting them. I’ll be attending and speaking at a workshop on Large Hadron Collider physics.  You can expect relevant blog posts in the next few days.

Personal and professional activities require me to take a short break from posting.  But I hope, whether you’re a novice with no knowledge of physics, or you’re a current, former, or soon-to-be scientist or engineer, or you’re somewhere between, that you can find plenty of articles of interest to you on this site.  A couple of reminders and pointers:

* If you haven’t yet seen my one-hour talk for a general audience, “The Quest for the Higgs Boson”, intended to explain accurately what the Higgs field and particle are all about, while avoiding the most common misleading short-cuts, it’s available now, along with a 20-minute question and answer session.

* If you want a slightly more technical and written discussion of the Higgs field and particle, complete with animated images, and suitable for people who may once have had a semester or two of university physics and math, try this series of articles first, and then go to this series.

* If you’d like to better understand the language of “matter”, “mass”, and “energy” that is everywhere in popular explanations of science, but eternally confusing because of how different authors choose to talk about these subjects, you might find some useful tips in these articles: #1, #2, #3, #4.

* If you need a reminder about what “ordinary matter” (i.e. things like pickles, people and planets) is made of, try this series, which goes all the way from molecules down to quarks.

* If you’re curious about what “particle/anti-particle annihilation” does and doesn’t mean, try this article.

* And here are the types of particles and forces of nature that we know about, and (for the moderately advanced reader) here’s how they’d be rearranged if the Higgs field were turned off.

Hopefully there’s something on that list that interests you, and many links within those articles to other things that may even interest you more.  Have fun exploring!  And stay tuned; I’ll be writing more in the near future…

So I think the time is approaching for a serious overhaul of this website.  First, there’s that new particle, which very much resembles a Higgs particle, though we’re not sure if it is of the simplest type; clearly many of the older pages on the website have to change to reflect this new information.  Second, the website has grown organically and now resembles an out-of-control thicket; it is difficult to navigate and to manage.  Moving pages around on a website, with all of their cross-links, is a major challenge and not necessarily advisable; one option is to provide a map or guide of some sort, with advice about which pages are devoid of technicalities, which are a bit more advanced and suitable for anyone with freshman physics background, and which ones are rather technical.  And after July’s big success at the Large Hadron Collider, August seems like the best month to get some of this work done.

But well before I start, it’s time for me to get advice from you.  The current purpose of the website is to help you answer your questions about particle physics and related subjects, including wider questions about how science is done. I am curious to know: what are the things about the website that make it difficult for you to find what you are looking for, and what are the things that you feel might help the most?  Please, in answering, consider letting me know what your level of background knowledge is, and perhaps some insight into your goals.  This information will help me understand your suggestions in proper context.

During the overhaul period I suspect blog posts will be somewhat reduced in quantity, but I’ll keep you posted on especially important issues.   And I’ll be producing my “How the Higgs Field Works” series, as well as tying off some loose ends on a couple of other incomplete series.

Today is the anniversary of this website, born June 29, 2011. And it’s just in time for what could be the biggest news in particle physics in many years.  If we’re lucky, on July 4th the teams that run the ATLAS and CMS experiments at the Large Hadron Collider [LHC] will reveal strong evidence for a Higgs particle of some type [for more info and background click here]. Or, if we’re equally lucky, they’ll reveal strong evidence ruling out the simplest type of Higgs. Only if the results are ambiguous will we have to wait yet again for another six months of data.

Why does this website exist?  For one thing, I thought perhaps I could help address the desire of many in the public to understand more about particle physics and about the process of doing science.  Also, I was concerned that if the Higgs did not show up in 2012, there was a big risk of public and media misinterpretation of the scientific situation, which I hoped I could help counter.  And with the recession taking down my long-standing LHC research plans, I was looking for some non-scientific way to be useful.

The year has been a mixed bag.  The site’s been quoted several times in the media, and science journalists have told me they’ve found it useful.  On the other hand, the site’s readership, which leapt to about 2000 hits a day early on, has stayed fixed at that level for more than eight months. Then there are the controversies. I don’t think one can run a useful modern website without a blog that reports the news in the field, and to properly address important issues with real integrity requires one to take unpopular stands on controversial issues. Unlike some of the other more populist bloggers out there, who seem to thrive on this kind of thing, I hate it. And finally, communicating particle physics is fun and rewarding, but also problematic.  Much of my readership has also read Brian Greene, Lisa Randall, Lenny Susskind, and the like… and will (or should!) soon be reading Sean Carroll’s upcoming book on the LHC and the Higgs… and all of us well-meaning physicists are explaining the same things in slightly different ways.  I’m worrying we’re creating, collectively, a lot of confusion.

For now, the website will continue as is, through the LHC Higgs presentations and into the follow-up period in early July. If strong evidence for the Higgs emerges, the immediate dangers that helped motivate the site’s existence will recede for a few years; there will be general agreement, as there should be, that the LHC has been a resounding success and has a bright scientific future ahead of it. In that case I’ll take a break from reporting all but the most important news (I recommend Resonaances and Cosmic Variance as news sources) and instead will focus on giving the website a needed reorganization; right now it’s very hard to navigate. As for whether the site has a future, and what form that future might take, that will take some thought.

So, a quiet Happy Birthday to this website Of Particular Significance. And then let’s look forward to the news that really matters — the news from Nature — and get the cases of champagne ready, in case the time has finally come to pop the corks.

Reminder: I’m giving a public lecture about the Large Hadron Collider today, Saturday, April 28th, 1 p.m. New York time/10 a.m. Pacific, through the MICA Popular Talks series, held online at the Large Auditorium on StellaNova, Second Life.  You’ll need a Second Life viewer to watch it live.  Should you miss it, both the audio and the slides will be posted later for you to look at.

[If you are a layperson interested in the faster-than-light neutrino claim, and you haven’t yet looked at yesterday’s “open-space’’ post and the list of excellent questions laypeople have asked in the comments, you definitely should.  And ask your own if you want. That post also gives an organized list of links to all my posts on the neutrino experiment so far.]

Now, here’s a problem: How should a particle physicist budget his or her time, when faced with the OPERA experiment, which has, say, a 1% chance of representing the most important discovery in decades, and a 99% chance of being wrong?  After all, life goes on at normal speed — and in particular, the Large Hadron Collider (LHC) is continuing to gather important data at an accelerating rate.  (more…)

Ok, the third video clip from my talk at the Secret Science club from March 2011 is now uploaded for your enjoyment.  [But watch the other two clips first, it will make it a lot easier to follow!]  Learn how to find the Higgs particle!  (Or at least the easier ways — an explanation of the harder techniques, some of which are important in the current hints of a Higgs signal, and further details on the easier techniques, will be posted very soon.)

Attentive viewers will notice that in one of my plots of simulated data the Higgs particle has a mass between 140 and 150 GeV.  I promise you 🙂 I had no advanced warning of this month’s hints!!  […which happen currently to favor this regime…]

Welcome to my new website!  This site will serve as a clearing house for all the wonderful conversations that I hope to have with the public about science, and for my posts with the answers to the most commonly asked questions concerning science most broadly, physics in general, my own field of particle physics, and the Large Hadron Collider in particular.
