The Dining Table

September 21, 2012 6 comments

During my tour of apartments as I was moving to Cleveland, I saw a dining table made by attaching four legs to a panel door and covering the top with glass to create a level surface. I decided to build one for myself, and instead of a funky pastel color and clips to hold the glass in place, I wanted to design something more elegant. Here is the result:




Here are some photos of the work in progress, starting with the door as purchased from the Habitat for Humanity ReStore:

I Wish I’d Written This

January 14, 2012 1 comment

On a hill by the Mississippi where Chippewas camped two generations ago, a girl stood in relief against the cornflower blue of Northern sky. She saw no Indians now; she saw flour-mills and the blinking windows of skyscrapers in Minneapolis and St. Paul. Nor was she thinking of squaws and portages, and the Yankee fur-traders whose shadows were all about her. She was meditating upon walnut fudge, the plays of Brieux, the reasons why heels run over, and the fact that the chemistry instructor had stared at the new coiffure which concealed her ears.

A breeze which had crossed a thousand miles of wheat-lands bellied her taffeta skirt in a line so graceful, so full of animation and moving beauty, that the heart of a chance watcher on the lower road tightened to wistfulness over her quality of suspended freedom. She lifted her arms, she leaned back against the wind, her skirt dipped and flared, a lock blew wild. A girl on a hilltop; credulous, plastic, young; drinking the air as she longed to drink life. The eternal aching comedy of expectant youth.

It is Carol Milford, fleeing for an hour from Blodgett College.

The days of pioneering, of lassies in sunbonnets, and bears killed with axes in piney clearings, are deader now than Camelot; and a rebellious girl is the spirit of that bewildered empire called the American Middlewest.

A Kindle Owner’s Christmas Wish List

December 24, 2011 6 comments

Friends and loved ones, you know I like books, and right now you have the perfect book in mind for a gift. I’m looking forward to reading it. But don’t give me the book unless it would look impressive on a shelf (and very few books qualify). Instead, give me an Amazon gift card – or cash – and tell me what book you’re giving me. I will buy it for the Kindle and read it there.

Of course, if you do give me the actual printed book, I will still love you and be thankful and read it. But later on, when I’m moving apartments, I will lightly curse you because you’ve contributed to the amount of heavy stuff I have to pack up and transport, when it was totally avoidable.

Merry Christmas!

Pittsburgh Bus System: Some Answers, More Questions

November 28, 2011 1 comment

I’d like to follow up my earlier post on the Pittsburgh bus system with a more careful examination of facts collected from the website of the Port Authority of Allegheny County (PAAC), who operate the public transportation systems in Pittsburgh and its surroundings. I’ll take this in two parts:

  1. First, a quick survey of the PAAC website to get a qualitative sense of what they might be doing to improve the bus system.
  2. A closer look at their financial statements to understand how we got to where we are today.

1. Quick Survey: It’s apparent to anyone who rides the bus routinely that there is a lot of room for improvement in its operation. Is the PAAC working to improve things? Their website – http://www.portauthority.orgstates that they’re doing work to improve the actual operations:

In 2010, Port Authority began instituting route changes under its Transit Development Plan (TDP), the result of more than two years of planning and feedback from thousands of riders, all with the aim to make transit smarter and more efficient. …

More improvements are in the works, including bus stop consolidation and streamlined Downtown circulation. …

Port Authority also recently installed new fareboxes on its entire vehicle fleet in preparation for a new smart card system – called ConnectCard – that will be introduced in the near future. This system promises to make fare payment easier and more convenient for riders.

Well, then, some of the ideas I wrote about – fewer stops, simpler no-cash payment – are already in the works. In fact, the card reader that Pitt ID holders use, where we just tap the box, is part of the new system being unveiled.

2. Financial Statements: It’s common knowledge around these parts that PAAC is short on money. Briefly, they fund their operations from transit revenues (ex: bus fares) and from tax money – mostly state and local. As of my writing this, you can find the budget book for each year going back to the late 90s. I focused on 2004-present, since this takes us back to the previous CEO’s tenure.

Each year’s budget book is ~ 200 pages long. So there are LOTS of financial data to parse, peruse, and plot. Let’s look at this figure I put together:

The blue bars show the total operating expense each year. Refer to the left axis. Operations are the cost of running the services each day and paying everyone responsible; separate from “capital projects”, which covers the purchase of new equipment and building new bridges or such. The actual numbers are shown, except for 2010 and 2011, which are projected numbers since the actual number is reported in the budget book two years later.

The purple bars show the bus-specific expenses from within the Transit Operations. Refer to the left axis. The bus-specific expenses include salaries and wages, “fringe benefits”, and material/supply costs, e.g., fuel. In some years’ books, these are reported as one number; in some, they are broken out between Bus Operation and Bus Maintenance. In those cases, I’ve added together Operation and Maintenance so we can compare different years directly.

The markers and line in black show the number of employees each year in within Transit Operations, specifically for the bus system. Again, in the years that they were reported separately between Operators and Maintenance, I’ve added the two together so we can compare different years directly.

So what conclusions could we draw from this figure? Read more…

The 50 States – Updated December 2011

How many have you visited? Passing through a state doesn’t count for this list.

My total as of 18 Dec 2011: 26 states + Washington, D.C.

List of States

Alabama – fall 2005 to see the Gators vs. Alabama (Urban Meyer’s first year, the spread offense gets crushed, as do Tyrone Prothro’s lower leg bones)


Arizona – spring 2008 for a conference in Phoenix


California – first couple times were to San Diego in 2007; later, L.A. in 2010

Colorado – visited friends in Boulder, spring 2010, with a side trip to Casa Bonita in Denver, which is a real Mexican restaurant, not something South Park invented

Things I learned in Sweden – part 2

November 11, 2011 4 comments

4) Drinking more coffee than ever before: To say coffee is big in Sweden is an understatement. I’d say it’s one of the irreplaceable threads in the social fabric there. Two folks can discuss anything, so long as coffee’s been offered and accepted 🙂 If you have a day full of meetings, my thought is to select the espresso shot from the machine. The smaller volume of liquid will save you from repeated bathroom trips.

5) Meaningful relaxation: Interestingly, when you go to a coffee shop over there, you don’t see people studying. No laptops. (Working all afternoon in a cafe while hunched over that single coffee you grudgingly paid for – a most American phenomenon!) I was never a study-in-cafe type in the U.S. but being over there certainly nurtured my love for going into places that serve cake and pie along with their coffee… in the company of friends… to have actual conversations.

6) Identifying ways to create value: I was extremely fortunate to complement my research work with a program on how to commercialize new technologies originating in research. During the program, I got to actually develop some new partnerships along the way of testing one of my ideas on graphene dispersions. (I won’t go into the details here; I did give a presentation about it in Stockholm last month – watch it if you’re interested.) The great thing about doing this program was (a) the new thought processes I absorbed and can implement for future ideas, and (b) discovering that I find this new area of work – related to technology transfer, not the same as basic research – super interesting, challenging, and worth pursuing further. And of course, (c) getting introduced to a fantastic mentor who wasn’t hesitant to share wisdom from his broad life and business experiences. Thanks, Sten.

I’m going to end here. This is by no means an all-inclusive list. For example, I learned plenty of other good and useful things from my colleagues at Uppsala University. But those are for only me to savor, right now.

The first part of my list is here.

Is it Un-American to Ride Public Buses?

November 5, 2011 4 comments

The driver’s voice crackled over the speakers with his request for us to step further backward so new riders could board the bus. Step back to where? This bus was already loaded with folks going home from work. If the sardine were alive in the can, it would know our plight. On this hot Pittsburgh day, visions of a refreshing shower in the evening flashed through my mind, interrupted only by the riders wriggling past me to get off the bus. Although Pittsburgh’s buses have doors in their midsections, riders here are required to exit the bus at the same front door where they enter the bus.** On the crowded afternoon bus, this rule burdens riders seated at the back with the Herculean task of maneuvering to the front and ensures that we all trade sweat with our fellow riders. To further prolong our discomfort, on portions of the route the bus picks up and discharges passengers at successive blocks. Is it not excessive to have stops that are literally a stone’s throw apart from each other?

By the time I got home, I was eager to prescribe remedies for making the Pittsburgh bus experience a comfortable and efficient one. In a given neighborhood, for example, designate stops that are spaced farther apart. People can walk an extra block! The rest were similarly straightforward. Later, though, refreshed after my shower, I pondered if there were reasons—beyond my immediate perception—for the current mode of operation. Perhaps numerous stops were designated to accommodate riders with limited mobility?

** This rule seems to apply only during afternoon rush hour. All riders are allowed on the bus, and pay when they step off. Still, the question remains: WHY?

I wrote the above two paragraphs as part of an essay to work on transportation policy. You could call it my “Pittsburgh Bus Rant” – well, due to limited space, I couldn’t include my favorite bus-induced indignation: you’ve waited for a while (the bus rarely comes on time) and when it does arrive, it drives right past you because it is too full to take on new passengers. This has happened at all times of the day.

Clearly, I’m not the only one frustrated by this situation. Some clever people at CMU designed an app called Tiramisu to crowd-source in real time the bus timetable in Pittsburgh, so you’re not endlessly wondering when it’ll arrive at your stop. But this doesn’t address the underlying problem.

If someone grew up with this bus system, they might come to accept it as just-the-way-things-are. On the other hand, moving to Pittsburgh from a place where you could set your watch to the bus, I see room for improvement. Certainly, I acknowledge that European cities can have different layouts and can be more compact than American cities, but I refuse to believe that our engineering and logistical skill can’t address our unique transportation inefficiencies. Call it a sense of American exceptionalism, or whatever else you like. [Brief history recap: mass production of the automobile, the polio vaccine, sending men to the moon – all accomplished in the USA.]

So what are the hang-ups? Well, it looks like there’s been some short-sighted financial judgment by the Port Authority, and with the credit markets going south in 2008-09, now they’re short on cash. [Quick aside: The creativeness of the financial engineers on Wall Street has been, well, exceptional. When you have to invent words like “swaption” to describe your product…]

Now, these guys would like to rehire the bus drivers and mechanics that got laid off when the money dried up. Fine sentiment, but if you look at the bus schedule now, some of the routes have pickups every 15 or 20 minutes. If the buses were timely, that would suffice going through most neighborhoods. People who ride the bus care about the bus getting them to their destination at the time they planned for it to get them there. With a fraction of that cash, my recommendation would be to do an actual study of # riders vs. time of day in order to know who’s using your bus, when they’re using it, and where they’re getting on and off. So you can deploy regular-size buses when passenger traffic is light, and send the buses with the accordion-midsection when it’s known to be super busy. Also, stop charging $2.25 – people who don’t have the good fortune of using their ID card or monthly pass are subject to the annoyance of digging for that quarter. Alternately, avoid the transaction costs of cash ENTIRELY by switching to a pay-by-mobile-phone setup. This would not discriminate against anyone – everyone and their purse dog has a cell phone these days.

At the risk of sounding cynical about U.S. politics – these issues won’t be resolved because the decision makers are sequestered from the users. Could someone help me formulate an argument that goes like “PNC Bank / PPG / Heinz shareholders could see a steep improvement to their company’s bottom line as a result of (fill in the blank) which could be achieved with a more efficient Pittsburgh bus service”? After all, those folks have the lobbyists! 🙂
