Graduate school



After spending four years in college, I went directly to a PhD program in genetics. Throughout that time, I was often asked how long it would take to get my PhD. Eventually, I came up with the formula that I’d be surprised if I finished in less than four years and I’d be disappointed if it took longer than six years. In the event, it took exactly five years from the day I arrived in Chapel Hill until the day I left for a postdoc position in St. Louis.

A few years later, I found a table in the Chronicle of Higher Education showing that the median time in a PhD program in Life Sciences was seven years. The median time from bachelors to PhD was nine years, since many people work for a couple of years before starting a PhD program. In retrospect, five years was pretty good, but when you’re in your 20s, it seems like a long time. And most of the work in my dissertation was done in my final year.

Pro tip: If you know someone in a PhD program, ask them about their project, not how long it will take for them to graduate. It's not like professional school, with a defined curriculum. Research outcomes are hard to predict in advance.

Tesla robotaxis aren’t coming any time soon

The idea of a robotaxi appeals to me. The day is not far off when someone—my wife, my daughter—will tell me I’m no longer safe behind the wheel. It would certainly be handy to call or text a robotaxi to drive to the grocery store, a show or a dentist appointment. So is that happening? “It turns out not even the people building Tesla’s self-driving tech trust Elon Musk’s extravagant claims about the company’s autonomous vehicles. “New reporting by Reuters interviewed nine former data labelers and a former self-driving engineer about their take on Tesla’s Full Self-Driving mode. The results were overwhelmingly negative, with seven of the data specialists admitting they wouldn’t ride in a Tesla in FSD.” *snip* “ In recent months, Tesla operating on FSD move have driven riders   into lakes ,   off bridges , and even into the path of   oncoming trains   — and those are just the incidents that get media exposure. Given these insiders’ direct access to terabytes’ worth of p...

Yes, the CDC can change its mind

The Nobel Laureate economist Paul Samuelson famously acknowledged in a Meet the Press interview: “Well when events change, I change my mind. What do you do?” This observation applies to the advice from medical authorities such as the CDC and WHO during the COVID pandemic. Some members of the public are fond of pillorying these agencies for having published different guidelines at different times, as though health officials are in the business of issuing ex cathedra dogma rather than responding to incomplete and ambiguous information. Science doesn’t deal in proof, it deals with the weight of evidence. A scientific hypothesis is one that is capable of being tested and falsified by experiment. I get it. I used to teach problem-based learning to first year medical students, and they often struggled with what to do with incomplete and ambiguous information, which is what physicians in clinics do every day. Sometimes, one cannot wait for all the tests to be completed and all the data analyz...

About that Trump lawsuit

So Trump is suing Rupert Murdoch for defamation because of the release of a salacious doodle. Nothing remarkable about Donald J. Trump weaponizing the legal system against his opponents, I know. But there are some things that do bear remark here: “ . . . he's suing Rupert Murdoch personally. But you know who he's not suing? Lachlan Murdoch, who's actually the chairperson of News Corp and Fox, who's actually the decision-maker. Rupert Murdoch has no official role there anymore. He's an adviser.   “So, I thought that was revealing in a lot of ways, because it isn't just about going after the entity. It's sort of this expansion spillover, trying to send as much of a message as you possibly can. He's sort of hitting every potential lever, not just against Murdoch and that empire, but then all the other media properties in the future. It's also about sending an example.” “HAYES: Yeah. That, to me, is the point here, is that these lawsuits are not lawsuits...
