Frustrated by a sense of global mispriorities , I blurted out some snarky and mildly regrettable tweets on the lack of attention to climate change in the tech industry (Twitter being a sublime medium for the snarky and regrettable). Climate change is the problem of our time, it’s everyone’s problem, and most of our…
Update: a newer version of this little project helps you make your complaints about daylight saving time—whether they’re for or against it—with clearer messages about whether keeping DST, abolishing it, or making it permanent would be best for your daylight preferences. Give it a whirl over at Observable.
Most technician textbooks do a very poor job of explaining the details of transistors' internal workings. First they assume that the Base current is somehow controlling the Collector current, then they try to explain how one current can affect another. These explanations invariably fail because Bipolar transistors…
Tại Việt Nam, sự gia tăng phổ biến của trò chơi điện tử đang định hình lại bối cảnh cá cược thể thao. Khi các game thủ trẻ đắm mình vào các cuộc thi ảo, niềm đam mê của họ sẽ
[Epistemic status: Speculative. I can’t make this post less condescending and elitist, so if you don’t like condescending elitist things, this might not be for you.] Developmental psych…
Metal bands aren't afraid to tackle serious topics in their lyrics. Here, we look at metal songs that deal with concepts in theoretical physics and cosmology.
Today, the WHO issued a report that says, in essence, processed meats and red meats are carcinogens. This has been reported in a variety of…
Second version of the 6 GHz FMCW radar now with SAR images
The annual Pinewood Derby in my Cub Scout troop was always an exciting time for my friends and me growing up. Just look how happy I am in this amazing digital photo composition that my dad put together using Microsoft PictureIt! 99:
One of the prevailing narratives of our time is that we are innovating our way into the future at break-neck speed. It’s just dizzying how quickly the world around us is changing. Technology is this juggernaut that gets ever bigger, ever faster, and all we need to do is hold on for the wild ride into the infinitely…
A better map of the difference between solar and standard time, and some trivia
A few weeks ago, Hensen et al., of the Delft University of Technology and Barcelona, Spain, put out a paper reporting the first experiment that violates the Bell inequality in a way that closes off…
A leftover glow unlike any other — of neutrinos — has finally been seen.
Bối cảnh cá cược thể thao của Việt Nam đang chứng kiến sự tăng trưởng đáng kể, được thúc đẩy bởi sự phổ biến ngày càng tăng của trò chơi. Khi ngày càng
Last month, a few days before NASA’s New Horizons probe made its historic flyby of Pluto, I posted a GIF of it doing so to Reddit .
First of all, don’t panic. I’m going to try in this post to introduce you to quantum field theory, which is probably the deepest and most intimidating set of…
Every now and then the orbital motion of a body doesn’t match our prediction. And that might lead to interesting discoveries.
Walk about 100 meters east of the Observatory's meridian line. Slow down to a crawl as your GPS approaches 0 degrees, 0 minutes, 0 seconds longitude. There's no sign and no line on the ground.

Scientific American writes about rescuing the enormous theorem (classification of finite simple groups) before the proof vanishes. How can...
Modified curve tracer is applying AC voltage. Horizontal axis represents voltage and the vertical axis represents current. In both cases, the curve always passes through zero voltage and current. This requirement must be met in order to be classified as a memristor.
CRISPR is a recently discovered genomic tool that could potentially revolutionize genetic modification and editing, including gene silencing, editing, activating, and other crucial functions. It has made a big splash in the synthetic biology community, and mentions of CRISPR have started cropping up elsewhere in the…
“What we call Man's power over Nature turns out to be a power exercised by some men over other men with Nature as its instrument.”
