Making a high-quality elevator isn't just about designing something that can safely go from one floor to another. Elevators are service items. That means that when you design an elevator, you also have to design for people — both individual desires and needs, and the desires and needs of a variety of cultures.
If engineering is really about designing socio-technical systems, then elevators are big, fat, obvious reminder of that dynamic in play. In a profile written for the Wall Street Journal, author Kate Linebaugh describes the work of Theresa Christy, a mathematician and Otis Elevator research fellow.
You press a button and wait for your elevator. How long before you get impatient and agitated? Theresa Christy says 20 seconds.
As a mathematician steeped in the theories of vertical transportation at Otis Elevator Co., Ms. Christy, 55, has spent a quarter-century developing systems that make elevators run as perfectly as possible—which means getting most riders into a car in less than 20 seconds. "Traditionally, the wait time is the most important factor," she says. "The thing people hate the most is waiting."
... The challenges she deals with depend on the place. At a hotel in the holy city of Mecca in Saudi Arabia, she has to make sure that the elevators can clear a building quickly enough to get most people out five times a day for prayer.

NASA’s Langley Research Center in Hampton, Virginia turns 100 this year. In celebration, the space agency produced this short documentary and enlisted Captain Kirk himself, William Shatner, to narrate. Here are just a few highlights from NASA Langley’s incredible history: • In times of peace and war, NASA Langley helped to create a better airplane, […]
Rio Celeste is a gorgeous Costa Rican river with a length that’s famous for its unusual turquoise waters. After decades of guessing, scientists finally determined the cause was aluminosilicate:
AntsCanada (previously) has an overpopulation problem in his yellow crazy ant colony, so he added two kinds of carnivorous pitcher plants. The resulting relationship between ant versus plant turned out to be quite fascinating.

Although fully autonomous vehicles aren’t yet allowed on public streets, they are poised to dominate the roads in the not-too-distant future. But before that happens, Apple, Google, Uber, and other companies now investing in self-driving tech are going to need talented developers that can account for the dizzying array of factors at play when a […]
