So you're planning ahead for your next trip to a remote location, and you try to make sense of those TripAdvisor listings. Great tool - there's a bunch of there around, but let's focus on that one here. It allows you to type in your preferences, location, restrictions, and it dumps a list of facilities together with easy access to the reviews of previous customers. How could we possibly live without it, twenty years ago?
Now, the point of this article is to make sure you can USE the data you are able to get on the web. I use to say "there's not such a thing as too much information", but then I shoud qualify that statement: it all depends on whether you have a brain and a will to put it to work. 
What is a photon jet? Despite their exotic name, photon jets are a well studied thing nowadays. The original studies were performed by experimentalists who aimed to test quantum chromodynamics: they used to spend their time discriminating prompt photon production in hadron collisions from backgrounds. I remember a lot of such studies were performed in the 80ies and 90ies by my CDF colleagues, especially within the "QCD working group".
The importance of the detection of single, isolated photons of high energy has risen enormously since then, given their role in the discovery of the Higgs boson. Photon jets are in fact the background to beat down if you want a neat peak of H --> γγ decays to pop out of a mass histogram constructed from events featuring two photon candidates.
Since yesterday, and for almost a week, the literature festival in Mantova hosts "ScienceGround", a quite innovative initiative at the boundary between a science fair, a workshop, a library, and a place to hang around together and exchange ideas and information. The location is the beautiful hall of the church of Santa Maria della Vittoria, where a modular and dynamically configurable space has been set up.
On September 4 to 8 the city of Mantova, in northern Italy, will be brimming with writers and readers. The event is called "Festivaletteratura" and brings together authors and consumers of books of all kinds, in a week-long kermesse with interviews, debates, public lectures, and the like. 
Version 2 of a thick textbook on particle and astroparticle physics is out, and you should have a look at it (well, at least if you're seriously interested in the topic!). The book, titled "Introduction to Particle and Astroparticle Physics" (not a very imaginative title, admittedly, but at least a faithful one) has a more descriptive subtitle: "Multimessenger Astronomy and its Particle Physics Foundations". It is authored by Alessandro de Angelis and Mario Pimenta, two acknowledged experts of the field. 
Do you know the works of Tim Blais, the guy behind "A Capella Science"? I sincerely hope you do, but otherwise this post is for you. Tim has a youtube page where he publishes his amazing works.

Tim sings modified lyrics of famous songs, and mixes them with multiple tracks of his own voice imitating each of the instruments of the underlying orchestra, or other choral voices. Until here you could well say there's nothing new under the Sun, except that Tim has been capable, through amazing mixing and editing skills as well as awesome vocal gift, of producing quite entertaining videos. But there is more.
