“Circadian entrainment is one of the areas of biology where mathematical predictions have been tested experimentally and confirmed.”

“Light signalling pathways from both phytochrome and cryptochrome photoreceptors regulate clock components to achieve entrainment in plants.”

“Furthermore, extraretinal photoreceptors appear to be involved in the photic entrainment of the circadian clock.”

“And when finishers sprinkle water on slabs during the finishing process, they cause air entrainments of 12 percent or more to be produced on slab surfaces.”

“The geographical scale and rhythms of such postulated multi-species entrainments are likely to depend on the scale and rhythms of the weather pattern.”

“But I thought it was just one of these bloomin' spoof entrainments.”
