The sun has a fantastic range of electromagnetic radiation, from high-energy gamma rays all the way to long wavelength radio waves.
A lesser-known rotary engine within cells is responsible for a substantial portion of gases and nutrients that sustain the biosphere.
As super-resolution imaging improves, the world’s smallest rotary motor continues to amaze.
Physical chemists are justifiably proud of their tiny motors that do little more than spin. How can they say that much more complex motors in life evolved?
