University of Oregon Chemist Uses Electrochemistry to Measure Coffee Flavor Profile

University of Oregon chemist Christopher Hendon has developed a novel method for measuring coffee's flavor profile using a potentiostat—an electrochemical tool typically used for battery testing. By sending an electrical current through coffee samples, the technique measures how electricity interacts with the liquid, providing a better assessment of flavor than existing methods. The study focused on roast color and beverage strength, the two variables most affecting sensory profile. Hendon successfully tested the method on four coffee bean samples, identifying the distinctive signature of a batch that failed quality control.

The Unanswered Question About Match Striking Speed Is Also a Meditation on What AI Can't Replace

A writer experiencing insomnia embarks on a quest to determine the speed at which a match must be struck to ignite, contacting Swedish Match and two professors. While never receiving a definitive answer, the author uses this minor mystery as a springboard to critique Silicon Valley's pursuit of frictionlessness through AI, arguing that the space between input and output—reflection, consciousness, meaning—cannot be collapsed by pattern-matching algorithms. The essay draws on Clarice Lispector and references Marc Andreessen and Sam Altman to warn of an emerging spiritual crisis.
