evermore, and other beautiful things
An Article by Linus the SephistIf all evidence of civilization on Earth was destroyed, and humans had to re-build society from the ground up, what would be different? Feynman reckons that pivotal scientific moments, like the discovery of the atom, will still happen in the same way. Perhaps mathematics will be similarly rediscovered.
Someone told me once in response to this question, no artwork would ever be recreated. The art we create – music, stories, dance, film – isn’t a fundamental element of the universe, or even of humanity. It’s unique to each artist. If you choose to create art, you leave something in the world that has never had a chance to exist before, and will never again have a chance to exist. There will never be another Beatles or Studio Ghibli or Picasso. Art, in its infinite variations of originality, is cosmically unique in a way the sciences will never be. Art immortalizes human experiences that would otherwise vanish in time.
Reality is Very Weird and You Need to be Prepared for That
An EssayWe might be closer than we think to cures for depression, hypertension, and yes, even obesity.
The answer to scurvy was just one thing, plus a few wrinkles — mostly “not all citrus has the antiscorbutic property” and “most animals can’t get scurvy”. This was only difficult because people weren’t prepared to deal with basic wrinkles, but we can do better by learning from their mistakes.
This means don’t give up easily. It suggests that there is lots of low-hanging fruit, because even simple explanations are easily missed.
Lots of theories have been tried, and lots of them have been given up because of something that looks like contradictory evidence. But the evidence might not actually be a contradiction — the real explanation might just be slightly more complicated than people realized. Go back and revisit scientific near-misses, maybe there’s a wrinkle they didn’t know how to iron out.
Tortured phrases
An Article by Holly ElseIn April 2021, a series of strange phrases in journal articles piqued the interest of a group of computer scientists. The researchers could not understand why researchers would use the terms ‘counterfeit consciousness’, ‘profound neural organization’ and ‘colossal information’ in place of the more widely recognized terms ‘artificial intelligence’, ‘deep neural network’ and ‘big data’.
Further investigation revealed that these strange terms — which they dub “tortured phrases” — are probably the result of automated translation or software that attempts to disguise plagiarism. And they seem to be rife in computer-science papers.
Why Most Published Research Findings Are False
A Research Paper by John P.A. IoannidisThere is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance.
A hypothesis is a liability
A Research Paper by Itai Yanai & Martin LercherThere is a hidden cost to having a hypothesis. It arises from the relationship between night science and day science, the two very distinct modes of activity in which scientific ideas are generated and tested, respectively [1, 2]. With a hypothesis in hand, the impressive strengths of day science are unleashed, guiding us in designing tests, estimating parameters, and throwing out the hypothesis if it fails the tests. But when we analyze the results of an experiment, our mental focus on a specific hypothesis can prevent us from exploring other aspects of the data, effectively blinding us to new ideas.
Letters to the Future
The lapse of many years
At this point I wish to emphasize what I believe will ultimately prove to be the greatest purpose of our museum. This value will not, however, be realized until the lapse of many years, possibly a century, assuming that our material is safely preserved. And this is that the student of the future will have access to the original record of faunal conditions in California and the west, wherever we now work. He will know the proportional constituency of our faunae by species, the relative numbers of each species and the extent of the ranges of species as they exist today.
— Joseph Grinnell, 1910
The Grinnell System
The recording of field notes was common practice for biological surveyors and naturalists generations before Grinnell. His system continues this tradition but is distinguished by its distinctive standardized format. It consists of three sections:
- The journal contains a narrative account describing the study site and summarizing each day’s activities and observations, including a list of species encountered. This section is often peppered with sketches, photographs, or maps.
- The catalog is a sequential record of all voucher specimens collected, each with a unique field number and the information needed for the specimen’s museum tag, such as its sex, mass, breeding status, and standard body measurements.
- Species accounts are species-specific summaries of information and observations, gradually accumulated over multiple days at a site or across multiple sites, that eventually grow to detailed summaries of physical description, seasonal behaviors, microhabitat associations, and other characteristics.
Separating the notebook in this fashion allows each section to have its own context-specific structure and format.
Jim's system
From the earliest days of my fieldwork until now, throughout a given day I jotted notes, typically in pencil, into a small, spiral-bound pocket notebook, remembering the admonition not to trust one’s memory but to record observations as continually as possible. I then transcribes these notes into my handwritten journal in the evenings on the best of days or every few days when an intense field effort allowed.
From 2000 onward, I would still takes pencil notes in a small pocket notebook in the field, but I transcribes these into a word-processor document with margins set for the size of our field note pages. I combined this document with my field catalog for a particular trip and eventually both would be bound in the same manner as standard, handwritten field notes.
This approach had the advantage of producing both an archival paper copy as well as an electronic copy. It was also easy to intersperse specialized maps and digital photographs, which had become the norm by this time, throughout the journal text.
John's system
I have two field notebooks: a “raw" notebook and my formal Grinnellian notebook.
In the field, I take all my raw notes in a waterproof notebook using a fine-point permanent pen (or pencil when its raining). The entries have virtually no structure other than the date at the top of (almost) every page.
At the end of the day, I transcribe the notes into my Grinnellian journal as if I were writing a latter to a colleague.
Record them all
You can’t tell often in advance which observations will prove valuable. Do record them all!
— Joseph Grinnell, 1908
Recommendations for field notes
Being an end-user of someone else’s field notes certainly gives you insight into the benefits of good note-taking skills. Our experiences as end-users and creators of archival field notes lead us to a few specific recommendations:
(1) Don’t get bogged down in the details of format or style.
Rules are counterproductive if they prevent a researcher from taking field notes in the first place.
You will get more return by focusing on your content than by refining your formatting.
(2) Compose your notes as if you were writing a letter to someone a century in the future.
Writing for an external audience requires you to be more explicit in your descriptions and to take less knowledge for granted. Avoid the use of abbreviations, symbols, and other shortcuts that only you will understand.
Ask yourself: How would you describe this to someone over the phone?
(3) It is better to spend five minutes writing the important details than twenty minutes writing the trivial ones.
