Instead of analyzing the movement of an empty state in the valence band as the movement of billions of separate electrons, physicists propose a single imaginary particle called a "hole".

A converted physicist not afraid of over-simplification, Valentino Braitenberg, has proposed a scheme so simple that it needs no diagram.

A physicist proposes that modified, limited time travel is possible, clarifying his arguments for lay folk with illustrations and anecdotes.

In fact, the theoretical physicist, J.M. Ziman, proposed that science is public knowledge and thus includes mathematics.

This spring four physicists proposed a different kind of brane clash that they say could do away with inflation, the polestar of Big Bang theorizing for 20 years, altogether.

And a physicist has proposed - quite seriously - that the state put a layer of white paint on rooftops to reflect rather than absorb heat.

Then in 1957, a physicist named Hugh Everett proposed a daring new explanation.

For example, some physicists proposed a power law with an exponent that was slightly different from 2.

A decade ago, a Danish physicist, Dr. Per Bak, proposed a theory of "self-organized criticality," based partly on attacking complex problems in terms of cellular automata.

Some physicists have proposed that it is the very act of observation that conjures up the hard edges of the familiar world.
