Read the
CNN report
on the seminal contributions of Professor
Nima Arkani-Hamed on the proof and
characteristics of
strings,
these hypothesized, extremely minute string woollies (much smaller than
electrons) that everything in the universe (multi-verses) is (are) made up of.
Born to Iranian
parents in 1972, both physicists in Houston, and after he earned his degrees in Toronto as a Canadian and then at Berkeley,
and with a detour via Stanford, Arkani-Hamed, the
Professor of Fundamental
Physics at Princeton's Institute for Advanced Studies,
who was lured there from his Harvard's professorship, is a world renowned
citizen with humility that the humanity is blessed with! He is acclaimed for his
energy, passion, creativity regarding extra dimension energy physics..
If a fraction of
Professor Nima Arkani-Hamed's novel theories are turned out to be confirmed by the forthcoming
experimental work at the soon to be completed Large Hardon Collider in
Switzerland this August, it would revolutionize our thinking paradigm about our
very own essence, let alone the universe! The Nobel prize then is simply a
miniscule token of recognition bestowed upon this quiet GIANT in his tender
30's!
And last but not
least watch Nima's plenary and his introduction by his peers:

Our current description of the basic interactions in
nature, based on the standard model of particle physics and general relativity,
is in spectacular agreement with all known experiments. However, it is almost
certainly fundamentally incomplete. In addition to difficulties associated with
strong quantum gravitational effects at the Planck length, sensible
quantum-mechanical theory of gravity, two striking facts about nature clues
suggest that we are missing a big part of the picture. The extreme weakness of
gravity relative to the other forces, as well as the huge size and flatness of
our observable universe, require absurdly delicate adjustments of the parameters
of the theory. We expect that new physical principles will be revealed to
address these puzzles — the "hierarchy problem" and the "cosmological constant
problem." Fortunately, these mysteries are associated with length scales—the
electroweak scale and the Hubble scale—which will be probed experimentally in
the near future with particle accelerators and cosmological observations.
Therefore theories which address these puzzles are likely to have experimental
consequences that will be checked in the next few years.
Nima Arkani-Hamed's research in theoretical physics
is driven by attempting to address these mysteries. Much of his work has
centered around addressing the hierarchy problem. Together with Savas Dimopoulos
and Gia Dvali, he suggested that the extreme weakness of gravity can be
attributed to the existence of large extra dimensions of space, perhaps as large
as 100 microns in size, with the scale of quantum gravity lowered to the
electroweak scale. This opens up the possibility that quantum gravitational
effects can be probed at accelerators and even in table-top experiments. In a
different direction, together with Andy Cohen and Howard Georgi he has
constructed models where (non-gravitational) extra dimensions are generated
dynamically from purely four-dimensional models. This has also led to new
approaches to the hierarchy problem. He has also investigated the possibility
that gravity is modified at large distances and times in an effort to address
various cosmological problems. Most recently, together with Dimopoulos, he has
explored the possibility that the fine-tunings for the cosmological constant and
hierarchy problems find a common explanation within a huge landscape of possible
low-energy worlds that may exist in string theory, leading to a novel proposal
for "split" supersymmetry at the large hadron collider.
