I expect we all agree that the presidency is not a job for a shrinking violet. We acknowledge that a president without self-confidence would be a disaster in the making. But just how confident do we want our president to be? Is the kind of extroversion that helps people succeed in modern political campaigns also…
I really like teaching Duke undergraduates. They are an ambitious and intelligent group. But sometimes their ambition and intelligence get in the way of creative thinking, especially in regards to careers. They all want to remain high achievers, so they know they must either become doctors, lawyers, investment bankers or business consultants. Not infrequently I…
The first time scientists sequenced a person’s entire genome, it took more than a decade and cost hundreds of millions of dollars. Currently, such sequencing takes less than twenty-four hours and costs less than $5,000: To put that into perspective, Myriad Genetics charges $3,000 to test for mutations in just two genes associated with breast…

Nothing like the Christian notion of heaven has been found out to about 10 billion light years. (One light year is almost six trillion miles.) With best wishes…”…

She visited my class this summer, and here are some of the things she taught them: The evolution of transparency in the industry: “2013 and 2014 have been really important years for transparency and…
Because so much of human thinking is dichotomous, even though so much of the real world exists on a continuum, we have strange phenomena like the one illustrated in the picture below. The picture shows the significance values of research findings, and reveals that there are many more articles published where the statistical significance of…
A former student of mine who now works at the Advisory Board recently emailed me some figures her company put together, offering a snapshot of how many people are being hired in oncology practices to help patients with their financial concerns: I am very eager to see what these figures look like over the next…
In a wonderful article on deep cave exploration, Burkhard Bilger shows how powerful comparison can be in putting an unfamiliar topic into context. He is describing the arduous work involved in deep cave exploration. He is describing the risks of being far, far inside the cave when a heavy rain on the surface begins to…
