It’s a theory-packed episode, so we’ve split it into two parts. ...
In 2020, Scientific American made waves with the provocative headline: "No One Can Explain Why Planes Stay in the Air." But is that really true? Dr. Graham Wild, senior lecturer in aviation science and technology at the University of New South Wales in Canberra, joins us to set the record straight.
Most of us throw our clothes in the wash without a second thought, but what if that habit is doing more harm than good? In this episode, Dr. Holly Kaye-Smith, social change expert and communications specialist, challenges the way we think about cleanliness, climate action, and everyday laundry.
From surprising stats (over 90% of washed clothes aren’t even dirty!)...
Are ice baths really the recovery miracle they're made out to be? We plunge into the science with Dr. Hunter Bennett, lecturer at the University of South Australia, exploring the pros and cons of ice baths, when they’re helpful, and when they might actually hinder your gains.
