Tadashi Tokieda Collects Math and Physics Surprises | Quanta Magazine
Sometimes adults have a regrettable tendency to be interested only in things that are already labeled by other adults as interesting. Whereas if you come a little fresher, and a little more naive, you can look all over the place, whether it’s labeled or not, and find your own surprises. [...]

And so that’s what you do. You just look around. And sometimes you feel tired, or you feel dizzy, or you feel preoccupied by other things, and you cannot do this. But you’re not always tired and you’re not always preoccupied. In those moments, you can find lots of wonderful things.

Donna Strickland's Wikipedia Page and Women Nobel Winners - The Atlantic
The construction of the Wikipedia page feels like a metaphor for a historic award process that has long been criticized for neglecting women in its selection, and for the shortage of women’s stories in the sciences at large. To scroll through the “history” tab of Strickland’s page, where all edits are recorded and tracked, is to witness in real time the recognition of a scientist whose story likely deserved attention long before the Nobel Prize committee called.

“If somebody else thinks something that you don’t believe in, just think they’re wrong and you’re right and keep going,” Strickland told a young scientist at the press conference following the announcement of her win. ”That’s pretty much the way I always think.”

That Time the TSA Found a Scientist’s 3-D-Printed Mouse Penis - The Atlantic
Airport security lines, it turns out, are a fantastic venue for scientists to try their hand at outreach. Various scientists are said to have claimed that you don’t really understand something if you can’t explain it to your grandmother, a barmaid, a six-year-old, and other such sexist or ageist variants. But how about this: can you successfully explain it to an TSA official—someone who not only might have no background in science, but also strongly suspects that you might be a national security threat? Can you justify your research in the face of questions like “What are you doing?” or “Why are you doing it?” or “Why are you taking that onto a plane?”

Znanstveni blog: Vrtec na razstavi o fuzijski energiji
Oblikovalci evropske potujoče razstave o razvoju fuzijskih elektrarn med ciljno publiko najbrž niso predvideli predšolskih malčkov. Tudi vodniki po razstavi v Ljubljani, večinoma doktorski študenti z Instituta Jožef Stefan in ljubljanske univerze, so bili nemalo presenečeni, ko je nekaj dni po odprtju razstave v galerijo vstopila četica malčkov. Vzgojiteljice so jih razporedile v manjše skupine, ki so se razpršile med razstavnimi eksponati. Nekaj jih je obkrožilo interaktivni model fuzijskega reaktorja ITER, drugi so obstopili maketo fuzijske elektrarne, največ radovednih pogledov pa sta pritegnili plazemska krogla in obročasta cev s plazmo. Vodniki so se medtem spogledovali: kdo bo razlagal? Kaj naj jim povemo?

Otroci so v hipu padli v zgodbo o novem viru električne energije: s pritiskom na gumbe so prižigali »plazmo« v interaktivni maketi reaktorja ITER in čisto nič jih ni motilo, da so za plazmo slišali prvič. Saj so tudi za elektriko, strelo, impresioniste in Sonetni venec prvič slišali šele pred kratkim. Lučke so nakazovale smer toka toplote v maketi elektrarne, voda je navidezno pognala turbine in na koncu majčkenih daljnovodov so se v hišah prižgale lučke. Vse jasno!

9 Tips For Communicating Science To People Who Are Not Scientists
3. Get to the point. As scientists we are trained to describe a ton of details and background information before we give the final results. This is the very nature of how graduate students are trained to write their theses and dissertations. It is how scientists deliver presentations at conferences. For the public or policymakers this approach basically needs to be flipped. The key points or findings need to be delivered very early (see below) and it needs to be concise (think elevator speech).

An alarming number of scientific papers contain Excel errors - The Washington Post
A team of Australian researchers analyzed nearly 3,600 genetics papers published in a number of leading scientific journals — like Nature, Science and PLoS One. As is common practice in the field, these papers all came with supplementary files containing lists of genes used in the research.

The Australian researchers found that roughly 1 in 5 of these papers included errors in their gene lists that were due to Excel automatically converting gene names to things like calendar dates or random numbers.

Science Isn’t Broken | FiveThirtyEight
As a society, our stories about how science works are also prone to error. The standard way of thinking about the scientific method is: ask a question, do a study, get an answer. But this notion is vastly oversimplified. A more common path to truth looks like this: ask a question, do a study, get a partial or ambiguous answer, then do another study, and then do another to keep testing potential hypotheses and homing in on a more complete answer.

Writing a model, from start to finish: A step-by-step tutorial of Ger Grouper | simulatingcomplexity
A secret is, most models do not spring forth from a modeler’s head fully formed. They are created in increments and along the way things change, plans evolve, and workflow shifts. In this post today I aim to show you how we created a model from a sketchy start to published article.

PLOS Computational Biology: Ten Simple (Empirical) Rules for Writing Science
We have found that—when it comes to abstracts—“more is more,” despite clear and abundant advice to the contrary.

This is an interesting and surprising result. An intriguing hypothesis is that scientists have different preferences for what they would like to read versus what they are going to cite. Despite the fact that anybody in their right mind would prefer to read short, simple, and well-written prose with few abstruse terms, when building an argument and writing a paper, the limiting step is the ability to find the right article. For this, scientists rely heavily on search techniques, especially search engines, where longer and more specific abstracts are favored. Longer, more detailed, prolix prose is simply more available for search. This likely explains our results, and suggests the new landscape of linguistic fitness in 21st century science.

Why Do We Have Allergies? - Digg
We might have more effective treatments if scientists understood allergies, but a maddening web of causes underlies allergic reactions. Cells are aroused, chemicals released, signals relayed. Scientists have only partially mapped the process. And there’s an even bigger mystery underlying this biochemical web: why do we even get allergies at all?

Busy Hands, Busy Brains | American Craft Council
The best people we’ve met and talked to in every field always say you can learn everything from anything. It means to really master any craft, you have to learn the chemistry and the physics and the engineering and everything else that goes into that – the tools, the manufacture. A ceramist may not be a real chemist, but if they’re glazing their surfaces, they sure as heck have a sense of chemistry that’s just as developed as any experimental chemist. They may not be able to write all the equations for all the chemical reactions, but they know how things interact, what they do, and how to get effects that probably academic chemists have never even thought of. In some ways they’re probably more creative chemists than the academic ones.

The World Is What It Is Today Because of These Six Innovations- page 1 | Innovation | Smithsonian
Once people started to read, and once books were in circulation, very quickly the population of Europe realized that they were farsighted. This is interestingly a problem that hadn’t occurred to people before because they didn’t have any opportunity to look at tiny letter forms on a page, or anything else that required being able to use your vision at that micro scale. All of a sudden there is a surge in demand for spectacles. Europe is awash in people who were tinkering with lenses, and because of their experimentation, they start to say, “Hey, wait. If we took these two lenses and put them together, we could make a telescope. And if we take these two lenses and put them together, we could make a microscope.” Almost immediately there is this extraordinary scientific revolution in terms of understanding and identifying the cell, and identifying the moons of Jupiter and all these different things that Galileo does. So the Gutenberg press ended up having this very strange effect on science that wasn’t about the content of the books being published.

Atomic Anxiety and the Tooth Fairy: Citizen Science in the Midcentury Midwest—Vol. 2, No. 4—The Appendix
A childhood fascination with the abstraction of science (reminiscent of Vannevar Bush’s postwar report) abounds: “I always loved science and things of the sort,” confided one young girl. “I hope you are successful in what you are trying to do for science and people.” Another boy praised the scientists for their bravery and selflessness, declaring that God would give them “an eternal reward” for their good deeds (one wonders if perhaps a classroom lesson on the Curies’ death from exposure to radium prompted him to imagine the CNI scientists’ work as a suicide mission). Many addressed their notes to the Tooth Fairy, and one kid began simply “Dear Science.”

Duhem–Quine thesis - Wikipedia, the free encyclopedia
The Duhem–Quine thesis (also called the Duhem–Quine problem, after Pierre Duhem and Willard Van Orman Quine) is that it is impossible to test a scientific hypothesis in isolation, because an empirical test of the hypothesis requires one or more background assumptions (also called auxiliary assumptions or auxiliary hypotheses). The hypothesis in question is by itself incapable of making predictions. Instead, deriving predictions from the hypothesis typically requires background assumptions that several other hypotheses are correct; for example, that an experiment worked as designed or that previous scientific knowledge was accurate.

A bibliometric analysis on rural studies in human geography and related disciplines - Online First - Springer
This paper performed a bibliometric analysis on rural geography studies based on the peer-reviewed articles concerning rural geography published in the SSCI-listed journals from 1990 to 2012. Our analysis examines publication patterns (document types and publishing languages, article outputs and their categories, major journals and their publication, most productive authors, geographic distribution and international collaboration) and demonstrates the evolution of intellectual development of rural geography by studying highly cited papers and their citation networks and temporal evolution of keywords.

Andrei Linde and the Beauty of Science : The New Yorker
Professor Kuo approaches Linde’s house, in a quiet California suburb. [...] “I have a surprise for you,” Kuo tells them. Then he says the magic words: “It’s five sigma at point two.” [...] Linde acts incredulous, even affronted. “What?” he shouts. “Just a second.” He makes Kuo repeat himself. “Five sigma,” Kuo articulates slowly. “Clear as day. R of point two.” [...] Inside the house, the scientists pop open a bottle of champagne. Linde says that he had no idea who would be at the door. His wife thought it must be a delivery and asked if he’d ordered anything. “Yeah,” he says now, “I ordered it thirty years ago. Finally it arrived.”

How far should we trust scientific models? – Jon Turney – Aeon
Repetition helps. Paul Bates, professor of hydrology at the University of Bristol, runs flood models. He told me: ‘The problem is that most modellers run their codes deterministically: one data set and one optimum set of parameters, and they produce one prediction. But you need to run the models many times. For some recent analyses, we’ve run nearly 50,000 simulations.’ The result is not a firmer prediction, but a well-defined range of probabilities overlaid on the landscape. ‘You’d run the model many times and you’d do a composite map,’ said Bates. The upshot, he added, is that ‘instead of saying here will be wet, here will be dry, each cell would have a probability attached’.

Who's Afraid of Peer Review?
"In fact, [the paper] should have been promptly rejected. Any reviewer with more than a high-school knowledge of chemistry and the ability to understand a basic data plot should have spotted the paper's short-comings immediately. Its experiments are so hopelessly flawed that the results are meaningless. I know because I wrote the paper. Ocorrafoo Cobange does not exist, nor does the Wassee Institute of Medicine. Over the past 10 months, I have submitted 304 versions of the wonder drug paper to open-access journals. More than half of the journals accepted the paper, failing to notice its fatal flaws."

E.O. Wilson's Advice for Future Scientists : NPR
"You need a lot of time," says Dr. Wilson. "It's a good idea to be alone a lot and talk to yourself. I don't know if—how many other scientists talk to themselves. I do so all the time silently. And I guess I risk my reputation for complete sanity by admitting that. And I've now wondered how many creative scientists, people who are constantly in search of new ideas, new ways of looking at things, new enterprises, talk to themselves in a way as though they were speaking to another person, and trying to open up new subjects, new ways to get into old subjects. And this is a very good mental process for doing original science."

Maybe academics aren't so stupid after all | OUPblog
" Strong-minded people like this can be incoherent in speech because they constantly think about criticisms that could be leveled against their idea. They constantly interrupt themselves to insert additions or digressions to defend what they are saying against any criticism. Sometimes the digression gets even longer as they move on from simple defense of their idea to an active attack on the criticism. This is a mind constantly on guard. [...] Their sentences are confused because it seems as though they can’t quite make up their minds; they are characteristically tentative and tend to undermine what they are saying by being unable to resist mentioning a telling criticism.[...] It comes from a tendency to feel loyalty to conflicting points of view. As soon as I start to say X, my mind is tickled by the feeling that Y is also a valid point of view. “Maybe I’m wrong. Uh oh. I can’t quite figure out what I really think. Should I change my mind?”

The Technium: The Post-Productive Economy
eGenerally any task that can be measured by the metrics of productivity -- output per hour -- is a task we want automation to do. In short, productivity is for robots. Humans excel at wasting time, experimenting, playing, creating, and exploring. None of these fare well under the scrutiny of productivity. That is why science and art are so hard to fund. But they are also the foundation of long-term growth. Yet our notions of jobs, of work, of the economy don't include a lot of space for wasting time, experimenting, playing, creating, and exploring.

Introductions seemingly should be easy to write, since they do not require details about methods and results or a discussion of the results. Besides, the introduction is usually found right after the abstract, where you already summarized the content for the reader. In actuality, however, writing a good introduction requires considerable time and thought.

A Conversation With Randall Munroe, the Creator of XKCD - Megan Garber - The Atlantic
What I like doing is finding the places in those questions where normal people -- or, people who have less spare time than I do -- think, "This is stupid," and stop. I think the really cool and compelling thing about math and physics is that it opens up entry to all these hypotheticals -- or at least, it gives you the language to talk about them. [...]
And the great thing with this is that once someone asks me something good, I can't not figure out the answer, you know? I get really serious, and I'll drop whatever I'm doing and work on that.

As We May Think - Vannevar Bush - The Atlantic
The owner of the memex, let us say, is interested in the origin and properties of the bow and arrow. [...] He has dozens of possibly pertinent books and articles in his memex. First he runs through an encyclopedia, finds an interesting but sketchy article, leaves it projected. Next, in a history, he finds another pertinent item, and ties the two together. Thus he goes, building a trail of many items. Occasionally he inserts a comment of his own, either linking it into the main trail or joining it by a side trail to a particular item. [...] He inserts a page of longhand analysis of his own. Thus he builds a trail of his interest through the maze of materials available to him.

And his trails do not fade. [...] A touch brings up the code book. Tapping a few keys projects the head of the trail. A lever runs through it at will, stopping at interesting items, going off on side excursions. It is an interesting trail, pertinent to the discussion.

Open notebook science - Wikipedia, the free encyclopedia
Open Notebook Science is the practice of making the entire primary record of a research project publicly available online as it is recorded. This involves placing the personal, or laboratory, notebook of the researcher online along with all raw and processed data, and any associated material, as this material is generated. The approach may be summed up by the slogan 'no insider information'. It is the logical extreme of transparent approaches to research and explicitly includes the making available of failed, less significant, and otherwise unpublished experiments; so called 'Dark Data'.

"An unusual new species of green lacewing (Neuroptera: Chrysopidae: Semachrysa jade sp. n.) is described from Selangor (Malaysia) as a joint discovery by citizen scientist and professional taxonomists. The incidental nature of this discovery is underscored by the fact that the species was initially photographed and then released, with images subsequently posted to an online image database. It was not until the images in the database were randomly examined by the professional taxonomists that it was determined that the species was in fact new."

EPJ Data Science - a SpringerOpen journal
EPJ Data Science offers a publication platform to address this evolution by bringing together all academic disciplines concerned with the same challenges:

how to extract meaningful data from systems with ever increasing complexity
how to analyse them in a way that allows new insights
how to generate data that is needed but not yet available
how to find new empirical laws, or more fundamental theories, concerning how any natural or artificial (complex) systems work

This is accomplished through experiments and simulations, by data mining or by enriching data in a novel way. The focus of this journal is on conceptually new scientific methods for analyzing and synthesizing massive data sets, and on fresh ideas to link these insights to theory building and corresponding computer simulations.

"[T]he new generation of scientists was too busy churning out bricks -- facts -- without regard to how they go together. Brickmaking, Forscher feared, had become an end in itself. "And so it happened that the land became flooded with bricks. ... It became difficult to find the proper bricks for a task because one had to hunt among so many. ... It became difficult to complete a useful edifice because, as soon as the foundations were discernible, they were buried under an avalanche of random bricks."

Wired Petri Dish Gives Real-Time Updates - Technology Review
A new prototype petri dish can create an image of what's growing on it and send that information to a laptop, all from inside an incubator. The prototype, dubbed the ePetri, was created from Lego blocks and a cell-phone image sensor, and uses light from a Google Android smart phone. [...] With ePetri, it's like getting continuous tweets from the cells rather than an occasional postcard.

The Search for a More Perfect Kilogram | Magazine
"[O]f the seven fundamental metric units—the kilogram, meter, second, ampere, kelvin, mole, and candela—only the kilogram is still dependent on a physical artifact. [...] The American prototype is one of some four dozen such national standards around the world, and each of those, in turn, is accountable to an even higher authority: a regal artifact called the international prototype kilogram. Familiarly known as Le Grand K and held in a vault just outside of Paris under three bell jars, it dates back to the 1880s, when it was forged by the British metallurgist George Matthey from an alloy of nine-tenths platinum and one-tenth iridium."

The importance of stupidity in scientific research
"Science makes me feel stupid too. It's just that I've gotten used to it. So used to it, in fact, that I actively seek out new opportunities to feel stupid. I wouldn't know what to do without that feeling. I even think it's supposed to be this way."

[I]t’s the not knowing – that tang of doubt and possibility – that keeps us playing with the world, eager to figure out how it works.

Maps of Citations Uncover New Fields of Scholarship - Research
When they describe what they're doing, Mr. Bergstrom and his colleagues speak like explorers, invoking geographical and urban imagery to describe the landscape their algorithms reveal. Mr. Rosvall compares moving through the scholarly landscape to trying to get from one Rockies mountaintop to the next; the team's challenge is to identify peaks and valleys and help researchers move past the barriers that separate them. Mr. Bergstrom likens the network of citations to a city that is "growing organically as you're trying to navigate through it." Capture it in the right sort of map, he says, and "if that map is there, the story of how fields are changing is all there in this big lattice of citations."

CERN Press Release
“When an experiment finds an apparently unbelievable result and can find no artefact of the measurement to account for it, it’s normal procedure to invite broader scrutiny, and this is exactly what the OPERA collaboration is doing, it’s good scientific practice,” said CERN Research Director Sergio Bertolucci. “If this measurement is confirmed, it might change our view of physics, but we need to be sure that there are no other, more mundane, explanations. That will require independent measurements.”
