Through a couple of different avenues I wandered, yet again, down a rabbit hole leading to the topic of this post. The first avenue was through my main focus on a particular machine learning topic th
Designing a cheap two-port vector network analyzer with good measurement accuracy.
Prior to WWII the U.S was a distant second in science and engineering. By the time the war was over, U.S. science and engineering had blown past the British, and led the world for 85 years. It happ…
The Apollo 13 astronauts were stranded in space. Their survival depended on if they could make a carbon dioxide absorber inside the spacecraft.
People say many things about entropy: entropy increases with time, entropy is disorder, entropy increases with energy, entropy determines the arrow of time, etc.. But I have no idea what entropy is, and from what I find, neither do most other people. This is the introduction I wish I had when first told about entropy…
Dolphin researchers are using Gemma and Google Pixel phones to try to decipher how dolphins talk to one another.
So, have a seat. Put your feet up. This may take some time. Can I get you some tea? Earl Grey? You got it.
I came to the NAB (National Association of Broadcasters) show this year with my Dad to learn more about time in broadcast and live production. I was expecting to learn more about grandmaster clocks, AV sync, timing in protocols like Dante, Livewire, AES67, and more—and I have. But then on the first day here I found…
Wait, wasn't this solved by the Romans? Anyway, my grandma ate lead paint and she was totally fine.
Researchers at Penn Dental Medicine and collaborators have used a clinical-grade antiviral chewing gum to substantially reduce viral loads of two herpes simplex viruses and two influenza A strains in experimental models.
Released today, a report of a study investigating the project’s feasibility will serve as input for the European Strategy for Particle Physics and be assessed by the CERN Council in the coming months
Woodpecker drumming may not be as immediately distinctive as birdsong—but by carefully listening to speed, duration, and rhythm you can still tell many species apart. Here are some tips.
Chris Grossack's math blog and professional website.
A figure from the study showing rock dripping from the craton. The researchers hypothesize that the dripping is caused by…
Sweeteners can kill drug resistant bacteria
I remember thinking at school when will I ever in my “real life” use maths. Well much to my utter surprise I’ve come to the stark realisation that there is a link between mathematics and crochet. …
Research from Anthropic on the faithfulness of AI models' chain-of-thought reasoning.
People hoping to build muscle with the support of a creatine supplement might be disappointed by new research that shows it has little to no effect when taken at the recommended level.
A breakdown of the sources of many air pollutants that damage our health and ecosystems.
Update: did you enjoy our April Fool’s day story? While sheep do roam the CERN site and exhibit interesting flocking behaviour, no evidence has been found of their quantum entanglement (yet). However, CERN is participating in the International Year of Quantum Science and Technology . You can see the list of public…
I’ve just uploaded to the arXiv the paper “Decomposing a factorial into large factors”. This paper studies the quantity $latex {t(N)}&fg=000000$, defined as the largest quanti…
We investigate the internal mechanisms used by Claude 3.5 Haiku — Anthropic's lightweight production model — in a variety of contexts, using our circuit tracing methodology.
Getting zapped with millions of volts of electricity may not sound like a healthy activity, but for some trees, it is, according to a new study. Published in New Phytologist, the study finds that some tropical tree species are not only able to tolerate lightning strikes, but benefit from them. The trees may have even…
A demonstration of how reentry tachyarrhythmias can develop in a system of excitable cells.
Some time ago, I saw this video by DIY Perks where they make artificial sunlight at home with a 500W LED and a gigantic (1.2m) parabolic reflector. I've been...
