heat
Winter is by far the oldest of the seasons
...and we feel warm because it is cold out-of-doors.
Retained as a quality
Thermal information is not differentiated in our memory; rather it is retained as a quality, or underlying tone, associated with the whole experience of the place. It contributes to our sense of the particular personality, or spirit, that we identify with that place. In remembering the spirit of a place, we can anticipate that if we return, we will have the same sense of comfort or relaxation as before.
Two thermal archetypes
The hearth, a refuge of dry warmth from a cold world, and the oasis, a preserve of coolness and moisture in a desert wilderness.
The notion of a thermal optimum persists
There is an underlying assumption that the best thermal environment never needs to be noticed, and that once an objectively "comfortable" thermal environment has been provided, all of our thermal needs will have been met. The use of all of our extremely sophisticated environmental control systems is directed to this one end—to produce standard comfort zone conditions.
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.
Predicted Mean Vote
A DefinitionThe predicted mean vote (PMV) was developed by Povl Ole Fanger at Kansas State University and the Technical University of Denmark as an empirical fit to the human sensation of thermal comfort. It was later adopted as an ISO standard. It predicts the average vote of a large group of people on the a seven-point thermal sensation scale where:
- +3 = hot
- +2 = warm
- +1 = slightly warm
- 0 = neutral
- -1 = slightly cool
- -2 = cool
- -3 = cold
The Evolution and Fate of Botanical Field Books
To serve as a reminder
Looking back at my notebooks now, the information seems fairly sketchy, often abbreviated, and fairly uninformative. The purpose was merely to serve as a reminder for when, that evening, I would write up my notes in a proper field book.
Sterile creatures
Now that we are in the era of personal computers, traditional field books are being replaced by computer files. By default such “field books” are sterile creatures—all the words are spelled properly, the location data are exact to a matter of a few feet, and everything is properly formatted. In the spring of 1998, I penciled my last entry into my signature field book with the bright orange cover. Thereafter I have maintained a computer-based field book.
Oh, all the right stuff is there, clear, crisp and, well, dull… I tend to be overly particular about it—the format has to be right, everything properly spelled, the descriptive sequence in the proper order, and even the observations drafted with the final publication in mind (rather than what I happen to see at the moment). The emotions of finding something new, once mentioned in my handwritten field books, are now missing, as if my mental editor says “no, that is not proper for a scientific journal.”
Further and further away
In looking over my own forty-five years of keeping a record of plant specimens, I find that I am personally moving further and further away from the words I generate, becoming more aloof and separate from the experience of the actual event of collecting, concentrating instead on the precision of where and when. It is merely record keeping for the sole purpose of giving the facts.
With the decline of letter writing and the sterilization of field books, what we are losing is the individual. Field books are like letters that are replaced by often ephemeral emails. I fear that as we move further into the computer age we will similarly lose the detailed historical record that field books once provided. Sadly, the personalities of botanists will also be lost, for such musings as might be found in a field book are often telling to those wishing to know more of the past.
