I really enjoyed the book Mathematica by David Bessis, who writes about his creative process as a mathematician. He makes a case that formal math is usually the last step to refine…

It would be more relevant to look at reading scores for children who specifically tuned into Reading Rainbow. I suspect the number of viewers was a small fraction of all children i…

At the State university where I teach, literally part of our mission statement is to graduate every student who we admit. It has become a big part of the messaging from upper admin…

I can think of two factors. First, some direct costs could be prohibited. But more importantly, to make this work universities would need to restructure to make all of their servic…

This sounds good in some niche cases, like an English class with a small class size and a highly experienced teacher. However of all the potential fads in higher education this one…

Agree. Academics are now going to write an extra $11k into their grants (=$15k if you count uni indirect costs), with the justification "I plan to produce Nature quality results". …

My layman's understanding of earthquakes is that they have a heavy tailed probability distribution which makes predictions fundamentally difficult. Does ML (as in this approach) ge…

I would agree with many others here who say publish it. In some fields there is an additional question of where to host it, lest your paper's impact outlast the lifetime of your cu…

For many of the papers I read (engineering) I would love to be able to click on symbols in an equation and have it link me back to where that term was first defined in the paper, e…

His recent podcast series called Bob Saget's Here For You is worth a listen, as a reminder of what we've lost. He really was deserving of the title America's Dad. RIP.

According to Table 2 their sample had 8,199 unvaccinated and 9,269 vaccinated. It seems odd that more cases were found in the vaccinated people, can anyone suggest why? Statistical…

The only saving grace is at least they know the word 'safety'. I've ridden with such guys too and yes they are assholes, but notably they espouse the same defensive riding opinions…

I used to ride a motorcycle, now I have an ebike. They seem equally safe to me, which is to say neither are safe at all if there are other people on the road. The only solution is …

People learn in different ways. Personally, I've always been a "learn by using my hands" person, and in college I was a meticulous note taker. I could never use the method you desc…

That can be really difficult. Having just read the fantastic addendum in the blog post, "HOW TO: Get tenure", I think there is good information in there for finishing a PhD too. My…

Look up acoustic impedance matching. By analogy, your ultrasound technician needs to smear ky jelly (or similar) on your skin to ensure a good connection between the transducer and…

Bubbles will come and go, unless you're really in the white water (where you probably aren't interested in depths anyway). You'll likely have success if you make a simple software …

I have some expertise here (have used sonar under breaking waves) and I'd say you're spot on. Bubbles act like acoustic black holes, they absorb sound like crazy. Whether you're tr…

I'm excited by the idea that entry level embedded stuff like Arduino and RPi will keep feeding a new generation of tinkerers, in the same way PCs did (speaking as a child of the 80…

In the Willamette valley where I live, we had plenty of bumblebees this year, along with the usual honeybees and some wasps. I don't know which particular species of bumblebees. Wh…
