# evol: hanging by a rope off a cliff, the vibrant pigments of bird feathers to trace the mechanics of evolution

<< All organisms depend on input of exogenous compounds that cannot be internally produced. Gain and loss of such dependencies structure ecological communities and drive species’ evolution, yet the evolution of mechanisms that accommodate these variable dependencies remain elusive.

# phys: to move (momentarily) in and out of existence by extracting something from nothing

<< According to Einstein, nothing can travel faster than light in vacuum. Because of this, it is usually assumed that the Cherenkov emission cannot occur in vacuum. But according to quantum theory, the vacuum itself is packed full of "virtual particles", which move momentarily in and out of existence. These ghostly particles are usually not observable but, in the presence of extremely strong electric and magnetic fields, they can turn the vacuum into an optical medium where the speed of light is slowed down so that high velocity charged particles can emit Cherenkov gamma rays. This is totally unexpected in a vacuum. >>

# phys: cloud-to-ground lightning often strikes twice (or more)

<< Lightning is a dangerous yet poorly understood natural phenomenon. Lightning forms a network of plasma channels propagating away from the initiation point with both positively and negatively charged ends-called positive and negative leaders. >>

<< Negative leaders propagate in discrete steps, (..) Positive leaders propagate more continuously and thus emit very little high-frequency radiation. >>

<< It has been inferred that positive leaders can become transiently disconnected from negative leaders, which may lead to current pulses that both reconnect positive leaders to negative leaders, and cause multiple cloud-to-ground lightning events. >>

<< The disconnection process is thought to be due to negative differential resistance ... >>
