Vehicle safety report

Eleven students and one instructor from Physics: Heat, Electricity, and Magnetism ran the twice-yearly Vehicle Safety Day today between 12.30 and 4.00 pm. Twenty vehicles were examined, about half of what would be expected if there had not been rain, and if the activity were held at the SAC. However, it was useful to have the shop and vehicle lift available.

If you planned to get your vehicle checked and were not able to because of the change of venue or some other reason, email and ask for an appointment.

Most safety checks were routine. The following specific problems were noted and are reported here so other vehicle owners can learn from them:
  1. Several vehicles had trouble codes, which were "pulled" and recorded for the owners to seek further help. Some trouble codes can be more or less safely ignored, but not all or even most. Even if you choose to ignore one, it's best to check it periodically to make sure a second code has not been triggered.
  2. One vehicle had uneven wear on the rear tires, down to the canvas on both inside edges. The same had also been in a recent front-ender, making a twisted chassis a real possibility. The owner was advised to get new tires, not to exceed 50 mph until he had done so, then to get an alignment, and not exceed 70 mph until he had done that.
  3. One vehicle was running rough and consuming large amounts of oil, as determined from low oil measured on the dipstick and the owner's knowledge of the last oil added or oil change. More than a quart of oil consumption between fillings of your gas tank is too much, and it is time to consider getting a different vehicle or a new engine. The exception is if the oil consumption is due to a leak, in which case the leak should be fixed.
  4. One vehicle had a loose dipstick mount, requiring a new 6mm set screw.
  5. One vehicle had a loose heat shield above the catalytic converter. This was easily and permanently repaired using self-tapping screws, thanks to our new vehicle lift.
  6. One vehicle had a loose hood gasket. This was refitted using pop rivets.
  7. One vehicle was consuming coolant. Using the check engine code reader we were able to narrow the fault to a lean fuel mixture, likely the cause of overheating, boiling away coolant. A visit to a competent vehicle diagnostician was recommended, to correct the lean mixture. If a vehicle is made to run with consistently lean fuel mixture, overheating will cause premature engine wear.
  8. One vehicle's wipers required adjustment.
  9. Three vehicles had lights out, requiring new bulbs. In future we will begin to keep a range of standard bulbs in stock. This generally won't cover headlights, which are specialized to vehicle make and often even to model, but it will cover some, if not most, reverse, brake, tail, side, and turn signal lights.
Thanks to all the students who assisted with this activity, as well as the Student Affairs and Maintenance Departments.

Climate change quiz for EII

The quiz will be given in class on Tuesday, April 25th. It is worth 10 points. There will be ten multiple choice questions (60%) and a short essay (40%).

The multiple choice questions will be based on our class discussion, as well as on the booklet Maine's Climate Future (2009) and the 2015 update, both available at this website:

The essay question prompt will be "Describe your own climate philosophy." You should prepare this essay ahead of time, and will be allowed to use one ordinary flash card of notes (three by five inches) for the purpose.

Tuesday, April 4, 2017

EII third and fourth assignments

Note: Your EII grade will consist of the four assignments (20%), a climate change quiz (10%), and participation (10%).

Assignment #3:

Create a script or storyboard for your final digital storytelling assignment.

  1. Choose a group, or chose to work alone. 

  2. Chose the environmental leader or issue you wish to highlight with a presentation. Remember, presentations may be audio, video, narrated slideshow or any of the choices listed below. The only requirement is that the presentation play itself (or be staged, if a traditional play or sketch)

  3. Prepare a storyboard and/or script

  4. Each individual or group member must hand in their own storyboard or script. In the next assignment you will come together to make only one final submission, but for now, you work alone. This is so I can be sure that each of you learns the basic techniques

  5. If making a video, study the You-Tube how-to below, and prepare a storyboard

  6. If making audio or a narrated slideshow, prepare a script

  7. Produce an introduction to your storyboard or script that explains your project, including thesis statement, evidence, and conclusion

  8. Hand in the introduction, plus the storyboard or script

  9. Due either Friday April 28th.

Assignment 4:
  1. Research an environmental leader or issue of your choice. You may work in groups or alone. Identify a thesis related to the issue and supporting evidence, as well as the environmental or conservation organizations that are working on the issue. Prepare a video, audio, narrated slideshow, or other media production built around the thesis, providing supporting evidence, highlighting the work of the leader and their organization

  2. Due either the last day of the semester (Wednesday May 10th) or in time for the student conference (Monday May 8th -- but there's an earlier deadline to apply) -- your choice. Student conference participation is optional, but may be
    recommended for the best products. Note: You have to register!

  3. The options are deliberately wide. Don't get lost in your choices! Pick an issue and format for your presentation that you or your group feel confident you can finalize, and then stick to it.

  4. Use "backwards design" to help structure and outline your presentation, and also to organize your schedule: Start with your topic, and decide on a thesis. Then decide what your want to achieve with this topic and thesis. What is the story that you want to tell, and to whom do you wish to tell it? From that, pick a media format that will best reach your audience, and then organize your schedule so you can deliver a product using this format.

  5. Workshop time will be made available during class hours and by appointment with the
    instructor so that you can get help with this project. The Quimby Library Media Technician is standing by to help you with video and other formats.

  6. Here is a winning example from a previous year

Examples of allowable media:

Video storytelling
Stage plays
Sketch comedy
Traditional video documentary
Narrated slideshows and presentations
Others, after timely negotiation with the instructor

ESS second take-home exam

Environmental Scenarios and Solutions
Second Midterm (Take Home) Exam
Professor Womersley
(Worth 20% of final grade)
Due Friday April 22nd by email or hard copy. Do not submit via Canvas. I will not grade examinations submitted via Canvas.

Answer all questions. If you don’t know an answer, put down what you do know.
You may research answers. Give diagrams if needed. Cite important research other than material given in class or in the texts for the class. You must work alone.

You are an environmental social scientist working as an informal advisor in conservation policy for a moderate New Vermaineshire state legislator. A more radical legislator has proposed a policy to begin privatizing state conservation lands. It seems to be gathering support with your colleagues. One attractive facet of the proposal is the reduced cost in taxation, once lands that do not produce tax, access fees, or logging revenue are off the state books. You are asked for help in countering these arguments.
Applying social insight
What social and psychological insight can you give your legislator as to how to pitch the status quo (non-privatization) to the public. What general social understandings should she use to build and sustain support among her constituency and the state residents as a whole. Can you, for instance, apply cognitive dissonance or Maslow's hierarchy of needs? Hint: Consider how the public typically uses conservation lands of different kinds, including state parks, forest, and wildlife management areas and how this will change after privatization.

Applying cultural cognition 
How can you apply the findings of Kahan et al, 2011 to this problem? How are constituents and residents likely to feel about the proposal to privatize, if they respond as did the subjects of the cultural cognition study? How might your legislator respond using insights gained from the study? Hint: Be sure to consider the different responses based on the cultural axis diagram (below)
Which is more sustainable, privatization or public ownership? Explain why in detail.


1) A similar, less far-reaching, but real proposal:

2) Kahan et al,

Today's question (for ESS, and perhaps posterity)

Ruling on the second travel ban

Friday, March 3, 2017


           TOADS   by Phillip Larkin
Why should I let the toad work
 Squat on my life?
Can't I use my wit as a pitchfork
 And drive the brute off?

Six days of the week it soils
 With its sickening poison -
Just for paying a few bills!
 That's out of proportion.

Lots of folk live on their wits:
 Lecturers, lispers,
Losels, loblolly-men, louts-
 They don't end as paupers;

Lots of folk live up lanes
 With fires in a bucket,
Eat windfalls and tinned sardines-
 they seem to like it.

Their nippers have got bare feet,
 Their unspeakable wives
Are skinny as whippets - and yet
 No one actually starves.

Ah, were I courageous enough
 To shout Stuff your pension!
But I know, all too well, that's the stuff
 That dreams are made on:

For something sufficiently toad-like
 Squats in me, too;
Its hunkers are heavy as hard luck,
 And cold as snow,

And will never allow me to blarney
 My way of getting
The fame and the girl and the money
 All at one sitting.

I don't say, one bodies the other
 One's spiritual truth;
But I do say it's hard to lose either,
 When you have both.

ESS first take-home exam

Environmental Scenarios and Solutions
First Midterm (Take Home) Exam
Professor Womersley
(Worth 20% of final grade)
Due Friday March 3rd by email or hard copy. Do not submit via Canvas. I will not grade examinations submitted via Canvas.

Answer both questions. If you don’t know an answer, put down what you do know.
You may research answers. Give diagrams if needed. Cite important research other than material given in class or in the texts for the class. You must work alone.

Microeconomic applications
You are a policy staffer working for New Vermaineshire state government in the Fish and Wildlife Division. You are asked to prepare an analysis of a proposal in the legislature to regulate moose permits using an online bidding system (similar to eBay) instead of the existing lottery. The same number of permits will be issued, only via open bidding. The only requirement to bid is that the bidder be a US resident and have taken a certified hunter safety course. The proposal is conceptually comparable to others advocating the privatization of natural resources and use of competitive bidding.

Specify in plain English, using diagrams if necessary, the effects on state revenue, on the price of permits, and which sections of the public will be either winners or losers as a result. State whether or not, in your own opinion as an experienced staffer, this policy is likely to be successful, reasoning from the available evidence and what you know of the local culture.

Macroeconomic applications
If the legislature of the state of New Vermaineshire chooses to implement the above policy, what would be the general macroeconomic effects to the state’s economy? List and detail these. Use diagrams if necessary.

Which is more sustainable, the lottery or the open bidding system? Explain why.

EII first assignment

Write a short essay (of four to five pages, double-spaced) tracking the food chain for two comparable items of food, and comparing these food chains. Be sure to pick items whose provenance that you can easily track, for instance, a loaf of bread from a local bakery whose proprietors give such information, versus one from a major national company whose website also provides such information. If you come up with blanks, make reasonable assumptions based on what you know of our food system.

Compare the two food chains. How do they rate, in terms of social and environmental impact? Can you find any ecosystems or communities that are affected? How are the ecosystems and communities affected?

This class is about logic and rhetoric. In particular, we need to work to make sure students improve their rhetoric. I want to see a lot of work done on sentences in these papers. Be sure to either 1) provide a final copy free of sentence errors, or 2) go through a drafting process to fix or remove sentence errors.

I am available during office hours or by appointment to coach you through an approach to sentence-level proof-reading techniques.

This paper is due in class in hard copy, or by email before class time Tuesday, February 28th.

Jimmy Carter's new solar panels

After a week in which we used the original Jimmy Carter solar panels to experiment with solar energy in my physics lab, news arrived that President Carter has gotten himself some new ones.

This made me very happy, and I'm very pleased for Mr. Carter.

Here's the news article to go along with the movie.

I don't have any pictures of us using the original panels for Wednesday's lab. Several students took pictures, though, so perhaps one of you could send some in. In the meantime, here's an older picture of the same experiment.

And here's a link to the one we sent to the Smithsonian.

The Academy strikes back


And this, for debate this week in faculty meeting:

MOTION:  The faculty endorses the following resolution and requests that the administration make it known to the public.

A resolution from Unity College faculty reaffirming our shared values

Whereas the President of the United States has appointed individuals to positions of power who have denied the widespread scientific consensus on climate change, promoted untruthfulness in public discourse, and endorsed racism, misogyny and religious bigotry; and,

Whereas these appointments violate principles at the core of Unity College’s mission, regardless of our individual political values; now, therefore, be it

Resolved, that the Unity College faculty

1. commit ourselves to the scientific method and the principles of objective inquiry based on fact and reason. Science is essential to the ways we analyze, understand, and solve the most difficult challenges that we all face. The denial of science and reason does harm to our society, our species, and the world we depend on;

2. reject every form of bigotry, discrimination, hateful rhetoric, and hateful action. For anyone in our region who may feel fear or oppression, our doors are open and we are ready to help. We pledge to work with everyone – students, faculty, staff, administrators, and community members – to defend these principles today and in the times ahead; and

3. commit ourselves to listen respectfully, empathize with others, and take actions to promote this value in our community and the wider world. As an academic institution, we have a responsibility to provide a safe and welcoming space for expressions of intellectual, political, identity, and philosophical difference. We consider our differences to be our strength. As public citizens, we believe this nation has the same responsibility.

ESS assignment on authoritative news sources

The purpose of this assignment is to give you practice in evaluating and choosing authoritative and factual sources of news. This assignment is a make up for a class meeting I must miss (on February 7th) and worth five points extra credit for the class as a whole.
  1. Pick a recent national news story.
  2. Identify three comparable sources that cover the story around the same time period (within a day or two, more if it's a slow-moving story). 
  3. One should be from a news outlet generally considered "serious," "mainstream," and independent, the other two should be from outlets that have a partisan slant. One of the two should have a right-wing slant, the other a left-wing slant.
  4. Compare the three articles in a short essay of between two hundred and three hundred words. Explain how the different sources slant the news. What techniques do they use to spin their story to their biased audience?
  5. Talk to me if you do not know how to choose the sources. (But part of the assignment is to research whether or not the sources are indeed generally considered biased.)
  6. Submit the essay and the three sources. Submissions should be via email. Microsoft Word is probably the easiest software to write the essay in. You don't have to paste in your sources. You can use Word to "hot-link" sources and any other bibliography at the end of your essay (to hot-link, highlight, then use control-K or command-K in MS Word).
Due Friday 10th February via email

Darweesh vs. Trump updates

A collection of materials for further study:

Attorney General Herring of Virginia:

"Today I am bringing legal action on behalf of the Commonwealth of Virginia against President Donald Trump and his administration for the unconstitutional and unlawful executive order of January 27, 2017. The Commonwealth has substantial interests justifying its intervention, and make no mistake, the Commonwealth of Virginia, and our people, are already being harmed by this Executive Order.

"As we speak, there are students at our colleges and universities who are unable to return to Virginia. We have professors, researchers, and employees at our colleges and universities and Virginia businesses who either cannot enter the country, or who will be barred from returning should they leave.
"We have been working around the clock since Friday to examine this Executive Order before reaching this conclusion. This is not an action I take lightly, but it is one I take with confidence in our legal analysis, and in the necessity of intervening to both protect the Commonwealth's own sovereign interests and vindicate its residents' civil rights.
"This order is unlawful, unconstitutional, and un-American, and action is required." 

More on this lawsuit:

The original court order:

It is still not clear that the Executive Branch has followed the court order. This next is from The Daily Show, Tuesday night. The feed was cut (via Direct TV) as Romero, head of the ACLU and the chief litigant, was speaking, very suspiciously.
