The paper catches the wave of exciting new developments in M-theory that
have taken place over the last year.
Does it describe a new discovery, methodology, or
synthesis of knowledge?
"There still so much to be
M-theory is the fundamental description of nature that unifies string
theories and allows us to describe string theory when the strings are
strongly coupled. The paper reviews the state-of-the-art in our theoretical
understanding of how extended objects such as membranes interact in
Would you summarize the significance of your paper in
The paper gives an overview of the progress and problems in the deep
foundations of M-theory as well as outlining some new ideas for possible
progress and new research directions.
How did you become involved in this research, and were
there any problems along the way?
I have been working almost continually in this field for 13 years and see
the questions posed by M-theory as crucial to our understanding of nature.
M-theory is about understanding the central questions in physics, such as
how to quantize gravity, and, as such, have always been of interest to me.
Where do you see your research leading in the
There still so much to be done, especially in understanding the "fivebrane"
(a five dimensional object predicted by M-theory).
Do you foresee any social or political implications for
At the moment none. This is foundational fundamental research.
