NODE a2b68d62Articles 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.

The article contains a serious inaccuracy -- it credits Adleman with
having invented the term "Computer Virus", when, in fact, it was
probably John Brunner in his novel "The Shockwave Rider" over ten
years earlier. It also inaccurately credits one of his students with
developing the first one as a test, when in fact they existed for a
long time before.

The notion of a computer virus predates THE SHOCKWAVE RIDER. Gregory
Benford used the notion in a short story published in AMAZING STORIES in
1973 or 1974. It was an idea mentioned in passing in a story taking
place in a mining town in Antarctica. (Sorry, but I can't provide any
more bibliographic data than that; I'm relying strictly on memory.)
Benford definitely used the word "virus" to describe how the thing
reproduces.
In 1975 (the same year that THE SHOCKWAVE RIDER came out) Laser Books
published the notoriously bad SEEDS OF CHANGE, by Thomas F. Monteleone.
Monteleone has the Evial Computer That Rules The World brought down by
feeding it something called a "Benford program," i.e. a virus.
I couldn't say for sure whether the idea of computer viruses was
original to Benford or not. He is a theoretical plasma physicist who in
his misspent youth worked at Lawrence Livermore National Laboratory in
the weapons program. It is possible that he worked on numerical
modeling of plasmas in a secure computing environment, and that viruses
were part of the threat models of the Livermore computer security
people.
If he did invent the idea, then he has a lot to answer for. . . .

re Hal Puthoff et al.'s "unconventional" theories on the nature of
matter, tnx for pointer to article, but a caveat: they are very
probably wrong, as are virtually all such attempts to overturn big
chunks of physics. Does the article mention that Hal is most famous
for his SRI work on remote viewing & spoonbender/magician Uri Geller
some years ago? That doesn't disprove his current notions (and I've
tried to read some of his technical papers, which he occasionally gets
published in mainstream peer-reviewed physics journals, but I don't
have the time or talent to poke holes in them; my Ph.D. is in
astrophysics and general relativity) but perhaps raises some
questions, if you're a skeptic by nature....
To give this msg a wee bit of crypto content, any news on the "quantum
cryptography" front? Although that subject does seem to me to be
legitimate physics, my current perception is that it's almost entirely
an intellectual exercise, and that the proposed applications
(key-distribution or the like) are contrived examples without
plausible real-world use (and with many security holes to boot). Am I
wrong?
