Measuring Scientific Broadness

I select a novel newspaper out today too it wouldn’t select happened without this blog.

Influenza A virus subtype H5N1 twelvemonth ago, I wrote a blogpost declaring that “academia is fucked up,” to quote myself because my words are the best words. In that blogpost, I had or so suggestions how to improve the situation, for illustration past times offering ways to quantify scientific activeness other than counting papers too citations.

But ranting on a weblog is similar screaming inwards the desert: when the dust settles you’re all the same inwards the desert. At to the lowest degree that’s been my experience.

Not so this time! In the calendar week next the blogpost, 3 guys wrote to me expressing their involvement inwards working on what I suggested. One of them I never heard of again. The other ii didn’t teach along too ane of them eventually dropped out. My hopes sank.

But too so I got a little grant from the Foundational Questions Institute too was able to supplant the drop-out amongst mortal else. So straightaway nosotros were 3 again. And I could truly pay the other two, which in all probability helped keeping them interested.

One of the guys is Tom Price. I’ve never met him, simply – believe it or non – nosotros straightaway select a newspaper on the arXiv.
    Measuring Scientific Broadness
    Tom Price, Sabine Hossenfelder

    Who has non read letters of recommendations that comment on a student's `broadness' too wondered what to brand of it? We hither suggest a agency to quantify scientific broadness past times a semantic analysis of researchers' publications. We apply our methods to papers on the open-access server arXiv.org too study our findings.

    arXiv:1805.04647 [physics.soc-ph]

In the newspaper nosotros suggest a agency to stair out how wide or specialized a scientists’ interrogation interests are. We quantify this past times analyzing the words they purpose inwards the championship too abstracts of their arXiv papers.

Tom tried several ways to quantify the distribution of keywords, too so our newspaper contains 4 dissimilar measures for broadness. We eventually picked ane for the original text, simply checked that the other ones give largely comparable results. In the paper, nosotros study the results of diverse analyses of the arXiv data. For example, hither is the distribution of broadness over authors:

It’s a near-perfect normal distribution!

I should add together that y'all teach this distribution alone afterwards removing collaborations from the sample, which nosotros select done past times excluding all authors amongst the discussion “collaboration” inwards the refer too all papers amongst to a greater extent than than thirty authors. If y'all don’t produce this, the distribution has a peak at little broadness.

We equally good looked at the average broadness of authors inwards dissimilar arXiv categories, where nosotros associate an writer amongst a category if it’s the primary category for at to the lowest degree 60% of their papers. By that criterion, nosotros detect physics.plasm-ph has the highest broadness too astro-ph.GA the lowest one. However, nosotros select alone ranked categories amongst to a greater extent than than 100 associated authors to teach sensible statistics. In this ranking, therefore, or so categories don’t fifty-fifty appear.

That’s why nosotros too so equally good looked at the average broadness associated amongst papers (rather than authors) that select a for sure category equally the primary one. This brings physics.pop-ph to the top, land astro-ph.GA stays on the bottom.

That astrophysics is highly specialized equally good shows upwards inwards our listing of keywords, where phrases similar “star-forming” or “stellar mass” are amid those of the lowest broadness. On the other hand, the keywords “agents”, “chaos,” “network”, or “fractal” select high values of broadness. You detect the transcend broadest too transcend specialized words inwards the below table. See newspaper for reference to amount list.


We equally good compared the average broadness associated amongst authors who select listed affiliations inwards for sure countries. The transcend scores of broadness become to Israel, Austria, too China. The correlation betwixt the h-index too broadness is weak. Neither did nosotros detect a correlation betwixt broadness too sex (where nosotros associated genders past times mutual kickoff names). Broadness equally good isn’t correlated amongst the Nature Index, which is a stair out of a country’s interrogation productivity.

Influenza A virus subtype H5N1 correlation nosotros did detect though is that researchers whose careers of a precipitous end, inwards the feel that their publishing activeness discontinues, are to a greater extent than probable to select a depression value of broadness. Note that this doesn’t necessarily tell much almost the benefits of or so interrogation styles over others. It mightiness be, for example, that interrogation areas amongst high contest too few positions are to a greater extent than probable to equally good live on specialized.

Let me live on clear that it isn’t our intention to declare that the higher the broadness the better. Indeed, in that place mightiness good live on cases when broadness is distinctly non what y'all want. Depending on which seat y'all desire to fill upwards or which interrogation plan y'all select announced, y'all may desire candidates who are specialized on a item topic. Offering a stair out for broadness, so nosotros hope, is a little footstep to honoring the large diversity of ways to excel inwards science.

I desire to add together that Tom did the mass of the operate on this paper, land my contributions were rather minor. We select or so other newspaper coming upwards inwards the adjacent weeks (or so I hope), too nosotros are equally good working on a website where everyone volition live on able to decide their ain broadness value. So remain tuned!

Outraged Nigh The Google Multifariousness Memo? One Desire You Lot To Mean Value Nigh It.

Chairs. [ Image: Verco ] That leaked internal memo from James Damore at Google ? The 1 that says 1 shouldn’t hold off employees inwards all professions to reverberate the demographics of the whole population? Well, that was a pretty dumb affair to write. But non because it’s wrong. Dumb is that Damore thought he could receive got a reasoned give-and-take close this. In the USA, out of all places. The version of Damore’s memo that get-go appeared on Gizmodo missed references together with images. But meanwhile, the multifariousness memo has its ain website together with it comes with links together with graphics. Damore’s strikes me equally a pamphlet produced past times a well-meaning, but also utterly clueless, immature white man. He didn’t deserve to get fired for this. He deserved mayhap a slap on the too-quickly typing fingers. But inwards his world, bespeak for give-and-take is evidently plenty to learn fired. I don’t commonly write close the underrepresentation of wo...

Dear Dr B: Should 1 Report String Theory?

Strings. [image: freeimages.com ] “Greetings doctor Hossenfelder! I am a Princeton physics major who regularly reads your wonderful blog. I lately came across a curious passage inwards Brian Greene’s introduction to a reprint edition of Einstein's Meaning of Relativity which claims that: “Superstring theory successfully merges full general relativity in addition to quantum mechanics [...] Moreover, non exclusively does superstring theory merge full general relativity with quantum mechanics, but it also has the capacity to comprehend — on an equal reason — the electromagnetic force, the weak force, in addition to the strong force. Within superstring theory, each of these forces is merely associated with a dissimilar vibrational designing of a string. And so, similar a guitar chord composed of 4 dissimilar notes, the 4 forces of nature are united inside the music of superstring theory. What’s more, the same goes for all of thing every bit well. The electron, the quarks,...

Particle Physics Right Away Belly Up

Particle physics. Artist’s impression. Professor Ben Allanach is a particle physicist at Cambridge University. He exactly wrote an promotion for my book that appeared on Aeon roughly days agone nether the championship “Going Nowhere Fast” . I’m kidding of course, Allanach’s essay has no relation to my book. At to the lowest degree non that I know of. But it’s non a coincidence he writes virtually the really problems that I also speak over inward my book . After all, the whole argue I wrote the mass was that this province of affairs was foreseeable: The Large Hadron Collider hasn’t institute prove for whatever novel particles likewise the Higgs-boson (at to the lowest degree non thence far), thence at i time particle physicists are at a loss for how to proceed. Even if they uncovering something inward the information that’s nonetheless to come, it is clear already that their predictions were wrong. Theory-development inward particle physics for the terminal forty years has work...
