Named after radio pioneer Heinrich Hertz.

In the Galilean transformation, there are two separate invariants that two inertial frame of reference always agree on between two separate events:

However, in special relativity, neither of those are invariant separately, since space and time are mixed up together.

Instead, there is a new unified invariant: the spacetime-interval, given by:

Note that this distance can be zero for two events separated.

Advantages of fog: there is only one, reusing hardware that would be otherwise idle.

Disadvantages:

All of this makes Ciro Santilli doubtful if it wouldn't be more efficient for volunteers simply to donate money rather than inefficient power usage.

Bibliography:

You modify the DNA of a cell and stick a fluorescent protein right before or after another protein. Then when it gets translated, the GFP is stuck to the protein of interest, which hopefully hasn't lost its function as a result, then you can just see the protein of interest.

TODO confirm, but looks like it, e.g. E. Coli starts DNA replication before the previous one finished.
