In AIP Advances, researchers share a model that identifies the optimal location for bowling ball placement. Employing a system of six differential equations derived from Euler’s equations for a rotating rigid body, their model creates a plot that shows the best conditions for a strike. The model accounts for a variety factors, including the thin layer of oil applied to bowling lanes, the motion of the subtly asymmetric bowling ball, and a “miss-room” to allow for human inaccuracies.

Ambisonic rendering is a way to simulate the precise locations of sounds in 3D, and an ambisonics algorithm has allowed researchers to create rich virtual “soundscapes.” In JASA, researchers decided to test the limits of ambisonic sound reproduction through their “AudioDome” loudspeaker array. Humans’ spatial acuity is high in front of our faces but decreases around the sides of our head, and the researchers’ experiments obtained very similar results from listeners in the AudioDome, proving that the loudspeaker array can reproduce sound locations at a spatial scale beyond the human limits of perception.

New research has uncovered how a simple circadian clock network demonstrates advanced noise-filtering capabilities, enhancing our understanding of how biological circuits maintain accuracy in dynamic natural environments.
