Using as a springboard a three-way debate between theoretical physicist Lee Smolin, philosopher of science Nancy Cartwright and myself, I address in layman’s terms the issues of why we need a unified theory of the fundamental interactions and why, in my opinion, string and M-theory currently offer the best hope. The focus will be on responding more generally to the various criticisms. I also describe the diverse application of string/M-theory techniques to other branches of physics and… 
The Many Dimensions of the String Theory Wars
String theory, over its near five decade history, has attracted a great deal of controversy, which continues to evolve to the present day. The string theory controversy has novel aspects which
Contested Boundaries: The String Theory Debates and Ideologies of Science
Over the last three decades, physicists have engaged in, sometimes heated, debates about relative merits and prospects of string theory as a viable research program and even about its status as a
Holography, application, and string theory's changing nature.
String theory, non-empirical theory assessment, and the context of pursuit
An analysis of the radical disagreement over the adequacy of string theory and how the argument patterns that have been posited by Dawid as constituting an emergent methodological revolution in science are better off if reworked as arguments belonging to the context of pursuit.
Constraints and divergent assessments of fertility in non-empirical physics in the history of the string theory controversy.

Grand challenges in mathematical physics
It is no easy task to write in a few lines a comprehensible list of Grand Challenges in the Frontiers of Mathematical Physics. This is such an extensive discipline, comprising at the very least (and
The ongoing impact of modular localization on particle theory
Modular localization is the concise conceptual formulation of causal localization in the setting of local quantum physics. Unlike QM it does not refer to individual operators but rather to ensembles
The Structure of Matter in Spacetime from the Substructure of Time
The nature of the change in perspective that accompanies the proposal of a unified physical theory deriving from the single dimension of time is elaborated. On expressing a temporal interval in a
Quantum Gravity from the Composition of Spacetime Constructed through Generalised Proper Time
We describe a theory amalgamating quantum theory and general relativity through the identification of a continuous 4-dimensional spacetime arena constructed from the substructures of a generalised


Disagreeing on Everything
As theoretical physicists, we deplore the publication of A. Garrett Lisi and James Owen Weatherall’s “A Geometric Theory of Everything,” as well as of Zeeya Merali’s “Rummaging for a Final Theory”
The Trouble With Physics: The Rise of String Theory, The Fall of a Science, and What Comes Next
The author argues that physics - the basis for all other science - has lost its way. He charts the rise and fall of string theory - an ambitious attempt to formulate 'a theory of everything' that
A geometric theory of everything.
Each week the CERN preprint library receives about 60 papers on theoretical particle physics of which about 25–30 are devoted to superstrings or related topics. So as I put pen to paper I feel the
Not Even Wrong: The Failure of String Theory and the Search for Unity in Physical Law
U-2 observations have revealed anisotropy in the 3 K blackbody radiation which bathes the universe. The radiation is a few millidegrees ho er in the direction of Leo, and cooler in the direction of
An Exceptionally Simple Theory of Everything
All fields of the standard model and gravity are unified as an E8 principal bundle connection. A non-compact real form of the E8 Lie algebra has G2 and F4 subalgebras which break down to strong
There is No “Theory of Everything” Inside E8
We analyze certain subgroups of real and complex forms of the Lie group E8, and deduce that any “Theory of Everything” obtained by embedding the gauge groups of gravity and the Standard Model into a
A theory of everything?
In his later years, Einstein sought a unified theory that would extend general relativity and provide an alternative to quantum theory. There is now talk of a ‘theory of everything’ (although
