The first study to measure the incidence of medication errors and adverse drug events during the perioperative period has found that some sort of mistake or adverse event occurred in every second operation and in 5 percent of observed drug administrations, according to information gathered from 275 operations at…
Highly-accomplished scientists are more likely to have an artsy hobby than the average scientist. And Nobel prize winners are even more likely.
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.

The Oh-My-God Particle
A deep dive summary into on of the most interesting books I read this year.
A visual example-focused introduction to neural networks.
MIT physicists captured the first images that directly show the pairing of fermions. The snapshots of particles pairing up in a cloud of atoms can provide clues to how electrons pair up in a superconducting material.
The American Astronomical Society (AAS) is an international non-governmental organization with a mission to enhance and share humanity’s scientific understanding of the universe as a diverse and inclusive astronomical community.
If you regularly read cognitive science or psychology blogs (or even just the lowly New York Times!), you’ve probably heard of something called the Dunning-Kruger effect. The Dunning-Kruger e…
Does DNB increase IQ? What factors affect the studies? Probably not: gains are driven by studies with weakest methodology like apathetic control groups.
On GPT-3: meta-learning, scaling, implications, and deep theory. The scaling hypothesis: neural nets absorb data & compute, generalizing and becoming more Bayesian as problems get harder, manifesting new abilities even at trivial-by-global-standards-scale. The deep learning revolution has begun as foretold.
All the colours in the light spectrum have complements that exist within the spectrum – except green. There seems to be some kind of imbalance. What is going on? Is green somehow being discriminated against? The light spectrum consists of a range of wavelengths of electromagnetic radiation. Red light has the longest…
It seems like each new day brings another one of those headlines: regular sleep “linked to” life expectancy, playing video games “associated with” surgical prowess, bullies “at risk” of becoming criminals, and “does breastfeeding reduce a baby’s blood pressure?” (the old rhetorical question gambit). Sometimes the…
This famous building stands in the business district of Rome--much as it was built some 18 centuries ago. Amazingly, it has withstood the ravages of both the elements and war permitting a firsthand view of a unique product constructed by Roman hands. Now, it is exposed to acid rain and fumes from passing automobiles…
The Nobel Prize in Physics 2010 was awarded jointly to Andre Geim and Konstantin Novoselov "for groundbreaking experiments regarding the two-dimensional material graphene"
So we all know how planes fly, right? The top of the wing is rounded and the bottom of the wing is more straight. Air takes longer to travel over the top of the
An email I was recently forwarded (a couple of steps removed) from Vinay Deolalikar from HP Labs:
Reviews the history of why psychologists moved from a word shape model of word recognition to a letter recognition model.
To demonstrate the problem, I did a simulation where I generated 480 random numbers per subject, representing the 480 time slices in the experiment. I repeated this generation of random numbers 20 times. I compared the send and no-send intervals of random numbers using a T-test; none of the 20 trials found a…
Self-reported life satisfaction differs widely between people and between countries. What explains these differences?
