On a dark ground, four lowercase letters sit in bold white type: meh. The period is part of the artwork. The word is set large enough that it reads from across a room, and the typeface is heavy enough that it does not look like a whisper. There is no animal beside it, no second […]
The Doorbell Notification as a Genre: Reading ‘There Is Motion at Your Front Door’
The graphic is small and complete. A white rounded rectangle sits at the top, the kind of banner a phone pushes down from the top of the screen. Inside it, a bell icon. Beside the bell, in plain sans-serif, the sentence: There is motion at your front door. Below the banner, a circle. Inside the […]
The Warning Label That Says Nothing About the Hazard
On the front of the shirt, the words NOT FRIENDLY sit above DO NOT TOUCH, set in the blocky, condensed capitals of a hazard placard. Between them, or beside them, a yellow caution triangle frames a hand with a diagonal bar struck through it. The palette is the one every industrial sign painter learned: yellow […]
The Ideal Observer: The Curve That Prices a Miss Against a False Alarm
The table is a grid. Rows of z-values run down the left margin, columns of hundredths run across the top, and the cells hold areas under the standard normal curve from 0 to z. It is published by the National Institute of Standards and Technology as part of the NIST/SEMATECH e-Handbook of Statistical Methods, and […]
Erlang’s Lost Calls: Queueing Theory Born in the Copenhagen Exchange
Erlang’s Lost Calls: Queueing Theory Born in the Copenhagen Exchange In 1908, the Copenhagen Telephone Company (Kjøbenhavns Telefon Aktieselskab, KTAS) faced a problem that had no name. Its subscribers were multiplying faster than its switchboards could accommodate them. Every new line added to the network increased the load on the manual exchanges, where operators sat […]
The Solow Residual and the Problem With Measuring Productivity
In 1957, Robert Solow published a short paper in the Review of Economics and Statistics. The paper did some subtraction. Solow took the growth of output in the American nonfarm economy between 1909 and 1949, subtracted the growth of the labor force, subtracted the growth of the capital stock, weighted each input by its share […]
Why Sheet Music Notates Silence More Precisely Than Most Strategy Documents
Why Sheet Music Notates Silence More Precisely Than Most Strategy Documents In August 1952, a pianist named David Tudor walked onto the stage of the Maverick Concert Hall in Woodstock, New York, sat down at a Steinway, and closed the keyboard lid. He held a stopwatch. After thirty-three seconds, he opened the lid. Then closed […]
The Problem With Measuring Productivity: What the Ratio Leaves Out
Every productivity number you have ever seen is a fraction. Output over input. Parts per shift, bushels per acre, billable hours per day, story points per sprint, revenue per employee. Measuring productivity is mostly the business of deciding what goes above that line, what goes below it, and what gets left out entirely â and […]
On the Flow State in Non-Athletic Contexts
Flow is a state of absorbed attention in which action and awareness merge, time distorts, and a task becomes its own reward. The term is usually associated with sport, but the same mechanism appears in drafting, coding, machining, surgery, editing, and other non-athletic work. This article treats flow as a material condition of attention: it […]
Why Sheet Music Notates Silence More Precisely Than Most Strategy Documents
Open an orchestral score to any page and you will find something most non-musicians never think to look for: silence, notated with the same architectural precision as sound. A rest in Beethoven’s Seventh Symphony is not a blank space. It is a measured duration, a shaped absence, a structural element with a specific onset, a […]
