    1. Live data from CERN accelerator screens

      Need to plan alternatives for periods of shutdown.

    2. Playing with particles to combine them to make atoms, molecules, …

      Go one step back: tune the Higgs field to give quarks the right mass so that neutrons are heavier than protons. If not, the protons will decay quickly and we can't have atoms.

      What happens if the Higgs couplings to quarks is too strong?

    3. Science Gateway exhibitions – overview of scenario

      Types of feedback sought:

      • Ideas for stories that can be told by scientists and engineers about their work that could illustrate (and humanise) this scenario – perhaps an anecdote about a particular challenge that has been solved in an innovative way or simply sharing the name of a great communicator I might not know.
      • Ideas for objects that could be available to illustrate the scenario.
      • Maybe you can share an idea for an experiment that you’ve seen in a museum somewhere or in a workshop, or know some-one at CERN who’s prototyped something that fits with our story?
      • Or perhaps there’s a new idea for an experiment or game that comes to mind when you read the scenario?
      • Also do you have an idea for a fun location that would tie the exhibits of Quantum World together?
      • Do you have suggestions for existing photos / film / VR / 360 degree images that you find particularly spectacular and that could be used at a particular point in the exhibitions? Or ideas for locations that it could be useful to film or photograph (particularly during LS2)?
      • …. or indeed any other input you’d like to share!
    1. Animals are not permitted on the CERN sites.

      on the CERN sites, except those required for medical reasons.

      "before planning your visit"?

    3. just before the summer

      See above comments.

    4. just before the summer

    5. available before the summer

      Should probably delete this.

    1. collaborator

      collaborator → volunteer

    2. collaborator

      collaborator → volunteer

    3. (everywhere)

      Delete "(everywhere)". Sorry my instructions weren't clear. :P I meant to say you need to replace the word "collaborator" with the word "volunteer" everywhere in the document.

    1. More information to come soon

      Should have a full stop at the end.

    2. Bookings will open before the summer.

      It's summer! This should change.

    3. Pre-book your visit to see specific points or sites, our interactive map can help you decide where you would like to go.

      The comma needs to be a semi-colon, or the second part should be a new sentence.

    1. Can we annotate this PDF using Hypothesis, when it has been shared viaCERNbox?

      No we can't. :(

    2. Hypothesis test

      Successful annotation.

      This doesn't work when sharing a PDF via CERNbox though.

    1. Area under L is meaningless.

      There is no "dP" in Poisson case, so you can't integrate here.

    2. “P(0 events | model true) = 5%, and 0 events observedmeans there is 5% chance the S.M. is true.” (UGH!)
    3. incarnations
    4. right

      "appropriate", not "right"

    1. Getting page views is not, per se, an indication of scientific quality.

      Then again, are citations?

    2. When I make an error in a blog post, I can go in and update it. I am pretty confident that I make approximately as many errors in my published articles as I make in my blog posts, but the latter are much easier to fix, and thus, I would consider my blogs more error-free, and of higher quality.

      It would still be good to have all the versions of the blog post available for examinations, so that readers can know when content has changed. [Edit: Ah, I see you addressed this later in this paragraph. I still think that even for the consumer you should be able to review versions.]

    3. Some blogs have Open pre-publication Peer Review.

      While @neuroamanda and I review each others' posts before "publishing them" via GitHub, in principle, anyone can leave their comments on apostilb before the article goes "live". For example: https://github.com/apostilb/apostilb.github.io/pull/70

    4. we need a stable scientific record
    5. I don’t see how anyone will become aware of this error when they download our article.

      … unless we openly annotate the original articles to point to retractions, corrections, replications etc.

    6. But if a blog has comments, at least you can see what peers thought about a blog post, giving you some data, and often very important insights and alternative viewpoints.

      Next step: enable hypothes.is!

    7. On average, it seems to me almost all blogs practice open science to a much higher extent than scientific journals.

      It would be good if this statement were itself backed by some data. :)

    1. In 2013, François Englert and Peter Higgs were awarded the Nobel Prize in Physics for the development of the Higgs mechanism.

      'The Nobel Prize in Physics 2013 was awarded jointly to François Englert and Peter W. Higgs "for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider"'


    2. It is encoded in a compact description, the so-called 'Lagrangian', which even fits on t-shirts and coffee mugs.

      And, although the Standard Model may not be written in stone, the compact description certainly is: https://home.cern/cern-people/updates/2013/03/standard-model-set-stone

    3. Actually, the addition of \text{h}.\text{c}. is not required for term 2, since term 2 is self-adjoint.
    4. we recommend using the term 'transformation' instead of 'decay', as this more accurately describes the physical process

      OH MY GOD YES! <3

      The term "decay" when applied to non-macro phenomena is terribly misleading for anyone who isn't a physicist.

      "Decay" has several meanings (see the Wikipedia page), but it would not be foolish to assume that the term is commonly associated with things like decomposition or biological decays. Even in physics, an orbital decay is a gradual process.

      "Transformation" is much more applicable, and is a term I've used myself over the last few years instead of "decay" in this context.

    5. where μ and ν are Lorentz indices representing the spacetime components
    6. Feynman diagrams

      "Let’s draw Feynman diagrams!" and more, on the Quantum Diaries blog: http://www.quantumdiaries.org/2010/02/14/lets-draw-feynman-diagams/

      EDIT: This is already referenced in the article, but I'll leave this link up as a pointer anyway.

    7. quantum field theory

      Here's a beautiful (if long) explanation of QFT, on the Stanford Encyclopedia of Philosophy: https://plato.stanford.edu/entries/quantum-field-theory/

    8. The latest success was the verification of the Brout–Englert–Higgs field by ATLAS and CMS at CERN's Large Hadron Collider in 2012. Both experiments successfully detected the quantised excitation of the BEH field—the so-called Higgs boson.
    9. the Brout–Englert–Higgs field interacts with particles that have mass (all particles except the gluon and the photon)

      Or is it that all particles that interact with the BEH field have mass? ;)

    10. Matter particles can be divided into three groups: quarks (q) and antiquarks (\bar{q}); electrically charged leptons (\ell) and antileptons (\bar{\ell}); neutrinos (ν) and antineutrinos (\bar{\nu}). Gluons (g) couple to colour charge, which only quarks, antiquarks, and gluons themselves, have.

      Typically, though, the matter particles (fermions) are grouped into two, depending on whether they interact with the colour charge (quarks) or not (leptons, which include both the electrically charged leptons and neutrinos).

      However, the division into three groups, as shown here, is helpful!

    1. global evaluation

      “Global evaluations might color presumptions about specific traits or influence interpretation of the meaning or affective value of ambiguous trait information. Thus, if we like a person, we often assume that those attributes of the person about which we know little are also favourable.” (Nisbett & Wilson, 1977, p.250)


    1. circumpolar

      "A circumpolar distribution is any range of a taxon that occurs over a wide range of longitudes but only at high latitudes; such a range therefore extends all the way around either the North Pole or the South Pole." –– Circumpolar distribution on Wikipedia

    2. austral summer

      i.e. summer in the souther hemisphere

      Austral on Wikipedia

    3. parsimonious

      conservative, in this case

    4. increasing population density

      Increasing densities may be due to populations becoming more concentrated due to whaling (limited area), although "the Californian Blue Whale population (historically a relatively small proportion of the global total) has rebounded to an estimated 97% of its pre-hunting population."

    5. repeated, stereotyped, low-frequency calls
