Strength from both mass and form
Warmed by the afternoon sun
Textbooks on water-system engineering state that supply mains are generally installed on the north side of the street in the Northern Hemisphere and on the south side in the Southern Hemisphere, so that the sun will warm them. In both hemispheres they are supposed to be on the east side of north-south streets, on the premise that the afternoon sun is warmer than the morning sun.
An emblem of friendship
Bridges make connections; they bring people together—a role that has made them a traditional emblem of friendship. Consider the town of Mostar in Bosnia-Herzegovina. When fighting between ethnic factions broke out there in the 1990s, nothing symbolized the social disintegration more clearly than the destruction of a sixteenth-century stone-arch bridge that had linked the two parts of the town on opposite banks of the Neretva River. And the emblem of efforts to heal the divisions is a rebuilt bridge, opened with fireworks and fanfare in July of 2004.
Routine design
When we think of bridges, it is the dramatic and monumental long spans that come to mind first, especially the lithe suspension bridges such as the Golden Gate and the pure geometric arches such as Sydney Harbour. But the majority of bridges are not such spectacular structures. Most of them are ordinary overpasses, with spans of 30 or 40 feet, carrying roadways or rails across other thoroughfares or over small streams. You see such bridges by the dozen on any drive down the Interstate. They may be lacking in glamour, but they are more representative of a bridge builder's art.
The engineering and construction of girder bridges are pretty routine these days, but the bridges are not quite standard items you order from a catalogue. The girders, whether of steel or concrete, are custom-build for each bridge, then trucked to the site and hoisted into place with a crane. The designer still has scope for variation and creativity, and it shows out on the highways: some overpasses are prettier than others.
The Art of Doing Science and Engineering: Learning to Learn
A Book by Richard HammingThe Art of Doing Science and Engineering is the full expression of what "You and Your Research" outlined. It's a book about thinking; more specifically, a style of thinking by which great ideas are conceived.

“Design” is now “Product”
An Article by Dorian TaylorDesign has very little to do with what tools or methodologies you use, or what your job title is, or what you have a degree in, or even anything like “creativity”; design is about your relationship to constraints. Rather: to what extent are you defining constraints rather than just obeying them? Design is about taking a universe of possibilities and converging onto exactly one outcome. Being handed a set of constraints which you treat like immutable laws of physics (because many of them are) and solving within that envelope is what engineering is. To wit: what most designers are doing most of the time is actually a form of engineering, and engineers are always doing at least some design.
This is because genuine design—the power to define constraints—is a privileged political position within an organization, and not everybody can occupy it. In other words, the “seat at the table” comes first. Design is Steve Jobs infamously dropping an iPod prototype into his fish tank, pointing at the bubbles coming out and yelling at his staff to make it thinner. It doesn’t matter what your title is; Jobs is the designer in that scenario.

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.
