Articles on Adelman and E=mc(2)
The New York Times has an interesting article today on the life
and career of Leonard Adelman, with remarks on RSA and public
key cryptography. Friendly, not technical.

And, while not directly related to crypto, the magazine "The
Sciences", published by the New York Academy of Sciences, has a
long article, "Beyond E=mc(2)", on a controversial theory that
mass is "only electric charge and energy".
The authors are: Bernard Haisch, Alfonso Rueda and H. E.
Puthoff.

Here is a brief excerpt:
Recent work by us and others now appears to offer a
radically different insight into the relation E=mc(2), as
well as into the very idea of mass itself. To put it
simply, the concept of mass may be neither fundamental nor
necessary in physics. In the view we will present,
Einstein's formula is even more significant than physicists
have realized. It is actually a statement about how much
energy is required to give the appearance of a certain
amount of mass, rather than about the conversion of one
fundamental thing, energy, into another fundamental thing,
mass.
Indeed, if that view is correct, there is no such thing as
mass -- only electric charge and energy, which together
create the illusion of mass. The physical universe is made
up of massless electric charges immersed in a vast,
energetic, all-pervasive electromagnetic field. It is the
interaction of those charges and the electromagnetic field
that creates the appearance of mass. In other words, the
magazine you now hold in your hands is massless; properly
understood, it is physically nothing more than a collection
of electric charges embedded in a universal energetic
electromagnetic field and acted on by the field in such a
way as to make you think the magazine has the property of
mass. Its apparent weight and solidity arise from the
interactions of charges and field.
Besides recasting the prevailing view of mass, this idea
would address one of the most profound problems of physics,
the riddle of how gravity can be unified with the other
three fundamental forces of nature. The electromagnetic
force and the weak force, which is responsible for nuclear
decay, have been shown to be two manifestations of a single
force, appropriately called the electroweak force. There
are tantalizing hints that the strong force, which binds
nuclei together, will someday be unified with the
electroweak force. But until now gravity has resisted all
attempts at unification. If the new view is correct,
however, gravity would not need to be separately unified.
Just as mass would arise from the electromagnetic force, so
would gravity.
