111 MPH Test Run a Big Deal for Midwest High-Speed Rail

Keith Barry:

If the most recent run of trials are successful, Amtrak passengers traveling on that route will see trains hit 110 MPH as soon as Thanksgiving. The end goal is to bring that speed of service to 75 percent of the tracks between Chicago and St. Louis in the next three years, reducing the travel time between the two cities by 90 minutes.

Aldous Huxley’s Predictions for 2000 A.D.

Matt Novak:

Perhaps Huxley’s most inaccurate prediction is his assumption that an increase in productivity will mean an increase in wages for the average worker. As we’ve seen over the last half a century, increased worker productivity has not led to a dramatic increase in wages.

Pondering industrial decay along the Northeast Corridor

Adam Davidson, writing for the New York Times Magazine:

While there are no universally accepted numbers, the United Nations Statistics Division calculates that the dollar value of goods made in America is at an all-time high of $1.9 trillion, just about even with China. The catch is that the number of American workers needed to create all that value has dropped steadily. In the mid-1940s, more than half of the New Jersey work force was in factories; today around 7 percent do. Thereare the same number of manufacturing jobs nationwide as there were in 1941, when the country was just more than one-third its current population.

Think about that a moment, for two reasons. First, the United States has three times more people today than it did in 1941.

Which brings up the second reason, and one that I think captures the zeitgeist of America today. We want to be all the things we once were, but the world won’t let us. It has moved on, and we can’t bring ourselves to admit it. Want proof? Look to places where the manufacturing economy has been hit hard, like the Northeast Corridor or my home state of Wisconsin

Hurricane Sandy and the limits of the smart grid

Yours truly, writing for NOVA:

We’re in the midst of a lengthy and expensive overhaul of our nation’s electrical grid, one that heralds a new, “smarter” future. Power generation and delivery haven’t changed much since the days of Edison and Tesla, but a new wave of technologies, known collectively as the smart grid, will modernize the industry. Some utility companies have already started down this road, installing smart meters that communicate demand with operators. But could smart grid technologies have helped during Hurricane Sandy, or any other large natural disaster, for that matter? The answer is yes and no, and which part of that answer is right depends on how you define the smart grid.

It's Global Warming, Stupid

Sharp words from Paul Barrett at Businessweek:

Yes, yes, it’s unsophisticated to blame any given storm on climate change. Men and women in white lab coats tell us—and they’re right—that many factors contribute to each severe weather episode. Climate deniers exploit scientific complexity to avoid any discussion at all.

Clarity, however, is not beyond reach. Hurricane Sandy demands it: At least 40 U.S. deaths. Economic losses expected to climb as high as $50 billion. Eight million homes without power. Hundreds of thousands of people evacuated. More than 15,000 flights grounded. Factories, stores, and hospitals shut. Lower Manhattan dark, silent, and underwater.

Bloomberg Backs Obama, Citing Climate Change

Raymond Hernandez, reporting for the New York Times:

In a surprise announcement, Mayor Michael R. Bloomberg said Thursday that Hurricane Sandy had reshaped his thinking about the presidential campaign and that as a result he was endorsing President Obama.

After months of not being discussed by either candidate, climate change is suddenly a part of the race. 

To cultivate better students, plant a few trees

Lone tree

Look at that tree up there. Do you feel smarter? You should, provided that you’re a teenager. And that tree above? Well, it’s should be right outside your high school’s cafeteria windows, or even your classrooms’. Better still if all of your school’s windows are filled with a similarly arboreal tableau.

That’s the upshot of a 2010 paper that reports on how the view out high school windows can influence students’ academic performance. That may seem limited, but this is science, where we have to take things one step at a time. This step involves high schoolers. It’s possible that such benefits extend beyond just high schoolers—after all, people who have views of nature while at work are happier at their jobs—but for now, it’s just high schoolers.

The study looked at 101 public high schools in southeastern Michigan. I presume they spanned a variety of socioeconomic conditions and geographic settings, though the author didn’t confirm that, so I can’t be certain. However, when calculating his final statistics, he did control for socioeconomic status, as measured by student participation in free and reduced lunch, ethnicity, school size, and age of the school building.

For each school, he also gathered a variety of environmental variables, including the area of the campus taken up by athletic fields, parking lots, and other landscaping, as well as the ratio of trees to shrubs to lawns in that landscaping. He measured the size of the windows in classrooms and cafeterias and noted whether students could eat lunch outside. Finally, he judged how nice those views were, how much nature they contained. It’s a somewhat subjective measure, but an important one nonetheless.

To see how those views affected students, the author considered three academic and two behavioral criteria—graduation rates, four-year college plans, percentage of students who won the Michigan merit award (based on standardized test scores), disorderly conduct, and truancy.

Lo and behold, views of nature did have an effect. Students who could see real nature outside their cafeteria windows were more likely to graduate, to plan to attend a four-year college, and to win a Michigan merit award. They were also less likely to commit a crime. The bigger the windows, the better the results in some cases, including for four-year college plans (they were higher) and criminal activity (it was lower). Classroom windows didn’t have a noticeable influence, perhaps because students spend more time staring at the teacher and the board than out the window. That’s probably a good thing.

Put simply, students performed better academically at schools with more nature around it and bigger cafeteria windows to view it. They were more likely to graduate, more likely to plan to attend college, and less likely to be miscreants. The opposite was also true. If the school was surrounded by a large parking lot or expansive athletic fields, students there were less likely to want to attend college.

Now, planting trees and installing floor-to-ceiling windows in the cafeteria isn’t suddenly going to turn a struggling school into a star performer. Socioeconomic conditions, quality of life at home, and classroom sizes all exert far more influence over student performance. But the results presented in this paper aren’t insignificant. Views of nature improved most measures by 5 to 15 percent. That’s pretty impressive.

It also suggests that we shouldn’t build schools as cheaply as possible, which often means fewer windows and more cheap cinder block.¹ Opening up the walls, and making the views worthwhile, could do wonders. A few trees here and there along with a little less mowing could boost student academic achievement, reign in delinquency, and do so inexpensively. It’s not going to solve the problems that plague many of our schools,² but planting trees is so simple that it would be foolish to ignore. What are we waiting for?


  1. I should know. My high school was one of those.
  2. See the previous paragraph for what really needs to be tackled.

Lower Manhattan National Park

Before Hurricane Sandy, Geoff Manaugh wondered what the New York City region would look like if massive flood barriers—similar to what some people have proposed in the past few days—lowered the Hudson and East Rivers and excavation exposed riverbeds’ slopes:

In 2057, massive flood-control structures protecting New York City from the rising seas required a redirecting of the Hudson and East Rivers northeast, into Long Island Sound. The resulting dams—the construction of which triggered small earthquakes throughout New England—allowed for the draining of the old riverbed south and east of Manhattan, revealing the unearthly geological circumstances on which this archipelagic metropolis sits.

Sounds similar to Atlantropa, but smaller and less audacious.

Casualties of Toronto’s Urban Skies

Ian Austen, reporting for the New York Times:

There is no precise ranking of the world’s most deadly cities for migratory birds, but Toronto is considered a top contender for the title. When a British nature documentary crew wanted to film birds killed by crashes into glass, Daniel Klem Jr., an ornithologist at Muhlenberg College in Allentown, Pa., who has been studying the issue for about 40 years, directed them here, where huge numbers of birds streaking through the skies one moment can be plummeting toward the concrete the next.

Hurricane Sandy has emboldened more scientists to directly link climate change and storms, without the hedge. 

Hurricane's effect on the Great Lakes

Mitch Smith, reporting for the Chicago Tribune:

Despite a four-state buffer between Chicago and the Atlantic Ocean, Sandy will affect weather patterns in Chicago. The National Weather Service issued a lakeshore flood warning for Lake Michigan that will be in effect from 1 a.m. Tuesday until 4 p.m. Wednesday. Waves fueled by Sandy’s winds could increase in size quickly by Monday night, National Weather Service meteorologist Richard Castro warned.

The Cook County coastline will likely see waves of 16 to 22 feet. A typical windy day in Chicago might bring waves of 4 to 6 feet, Castro said.

Manhattan Evacuation Plan Reveals Island’s Old Contours

Don Rogerson:

It is interesting to compare the evacuation map to a 1776 map of the island before much of the coastline was augmented by landfill. The eastern line of Zone A along the Hudson River runs along Greenwich Street, which was at the waterfront in 1776. The old slips on the East River extend inland to Queen Street, now Pearl Street, which is near where Zone A runs along the East River.

Wind map of Hurricane Sandy

I’ve linked to the Hint.fm live wind map before, but it seems particularly germane to post a still from today. The average wind speed across the United States is 10 miles per hour, and you’ll notice much of the Southwest is relatively still. Sandy is one big, windy storm.
