Mixing the bowspirit with the rudder

Well, the team-building exercise part of the trip didn’t turn out to be much, but my director’s unit from the office (software engineering, QA, documentation, and network operations) spent an enjoyable sail on Chesapeake Bay on the Woodwind II out of Annapolis—at least most of us had a good time.

The Woodwind II is a schooner, fitted with two masts and four sails: aft to fore, mainsail, staysail, fisherman’s, and jib. According to lore, the fisherman’s sail evolved from the practice of hanging fishing nets in the area above the staysail on the mainmast and aft of the jib sail at the bow: sailors found that the nets caught some extra wind, and so this space was filled with another sail.

a long spanThe idea of the team-building exercise was that we would split into four teams, two on yards controlling sails, one at the helm, and one navigating. Captain Duncan and his crew would teach each team the elements of the station, and then the teams would rotate around and we would teach each other. This didn’t work out so well in practice, but it did mean that most of us got a turn at the wheel as well as duty pulling rope. The crew were very good-natured about leading a group of clumsy office workers through the necessary tasks, along with fetching blown-away hats. And it probably didn’t hurt that one of us was an experienced sailor (Jody); there was lots of time on this 4-1/2 tour to kick back and swap stories. Captain Duncan kept up a good patter of historical lore (how Bloody Point got its name, for instance), bad jokes, and “tips” like “a stationary object [like a bridge piling] always has the right of way.”

On my turn at the wheel, I was beginning to get the feel of steering to trim as opposed to steering to course (or to a landmark) as we moved up the South River. I think it was when we crossed a stretch where a scattering of crab pots were set that crew member Rachel took over for me.

Loss of pressure

A recent paper by Erin F. Baerwald et al. as summarized in Science Daily, suggests the cause of many bat fatalities near wind turbines: rather than direct collisions with turbine blades, bats die from barotrauma, internal injuries caused by sudden changes in air pressure. Unfortunately, the researchers don’t have ready suggestions to mitigate the pressure changes and hence reduce the kills.

Once again, from Dalkey Archive Press

For Powell’s, Deb Olin Unferth interviews Stanley Crawford on the occasion of the reissue of his novel Log of the S.S. the Mrs. Unguentine.

Unferth: Where did the name Unguentine come from?

Crawford: A fairly typical experience for me upon hearing or seeing a somewhat striking name in print is to repeat it silently in a sort of involuntary way, to the point often of annoyance. Unguentine was probably one of those names. I didn’t realize or remember until much later that it was also a brand name.

I wrote up some notes on the book in 2003.

On the trail: 1

There’s a stretch of the W&OD near my office that I walk about once a week: it rises on an fenced embankment to meet a bridge that crosses Broad Run, so the fence posts are the high ground favored by Indigo Buntings in season. And it also crosses a power line cut and some ground that’s been cleared for development. I’ve seen Wild Turkey down there a couple of times. Anyway, on this evening’s walk, I saw a bird that we don’t seem to see (or notice?) much any more: flying in to perch on a pokeweed stalk replete with berries, a solitary Cedar Waxwing.

International Rock-Flipping Day 2008: 1

It’s IRFD today!

earthworm and cricketI warmed up with a quick look in my back yard. Under the cinder block that holds the back gate closed (long-deferred project) I found an earthworm (order Haplotaxida) and what I take to be a ground cricket (order Orthoptera). I didn’t even see the cricket until I downloaded the photo: I was watching something smaller in the field that doesn’t come out in the image.

The Glade after HannaI then moved down to the patch where I usually census for the Great Backyard Bird Count, a stretch of The Glade upstream from Twin Branches Road. The vegetation along the stream bank was still flattened by the runoff from storm Hanna, which passed through yesterday.

land slugI found fewer flippable rocks in this area than I expected, so I fudged a little and looked under some logs as well. Hence this nice example of a slug. Land slugs that breathe air get their own order, Pulmonata.

termitesOn the way back to the car, my last flip turned up some tiny pale worker termites, order Isoptera. If we count the pillbugs that I didn’t photograph, then my tally for the day is five orders.

14 questions

Top marks to the Obama campaign for responding thoughtfully to the 14-item battery of questions asked by Sciencedebate 2008.

12. Scientific Integrity. Many government scientists report political interference in their job. Is it acceptable for elected officials to hold back or alter scientific reports if they conflict with their own views, and how will you balance scientific information with politics and personal beliefs in your decision-making?

Scientific and technological information is of growing importance to a range of issues. I believe such information must be expert and uncolored by ideology.

I will restore the basic principle that government decisions should be based on the best- available, scientifically-valid evidence and not on the ideological predispositions of agency officials or political appointees….

In addition I will:

• Appoint individuals with strong science and technology backgrounds and unquestioned reputations for integrity and objectivity to the growing number of senior management positions where decisions must incorporate science and technology advice. These positions will be filled promptly with ethical, highly qualified individuals on a non-partisan basis;

• Establish the nation’s first Chief Technology Officer (CTO) to ensure that our government and all its agencies have the right infrastructure, policies and services for the 21st century. The CTO will lead an interagency effort on best-in-class technologies, sharing of best practices, and safeguarding of our networks;

• Strengthen the role of the President’s Council of Advisors on Science and Technology (PCAST) by appointing experts who are charged to provide independent advice on critical issues of science and technology. The PCAST will once again be advisory to the president; and

• Restore the science integrity of government and restore transparency of decision- making by issuing an Executive Order establishing clear guidelines for the review and release of government publications, guaranteeing that results are released in a timely manner and not distorted by the ideological biases of political appointees. I will strengthen protection for “whistle blowers” who report abuses of these processes.

Here’s hoping the McCain organization decides to take science and technology issues equally seriously, but I’m skeptical: the Obama responses have been posted for more than a week.
