the-euphemism-treadmill

I sometimes get annoyed with John McWhorter, but when he’s good he’s very good, and his Aeon essay on euphemisms is probably the best thing I’ve read on this vexed topic. The core of his point is in this paragraph: What the cognitive psychologist and linguist Steven Pinker has artfully termed ‘the euphemism treadmill’ is […]

Bioaccumulation of Microplastics in Decedent Human Brains

bioaccumulation-of-microplastics-in-decedent-human-brains

Abstract Rising global concentrations of environmental micro- and nanoplastics (MNPs) drive concerns for human exposure and health outcomes. Applying pyrolysis gas chromatography-mass spectrometry (Py-GC/MS) methods to isolate and quantify MNPs from human samples, we compared MNP accumulation in kidneys, livers, and brains. Autopsy samples from the Office of the Medical Investigator in Albuquerque, NM, collected […]

Euclid proved that √2 (the square root of 2) is an irrational number. He used a proof by contradiction. First Euclid assumed √2 was a rational number. A rational number  is a number that can be in the form p/q where p and q are integers and q is not zero. He then went on […]
