We review recent work in which compactifications of string and M theory are constructed in which all scalar fields (moduli) are massive, and supersymmetry is broken with a small positive cosmological constant, features needed to reproduce real world physics. We explain how this work implies that there is a ``landscape'' of string/M theory vacua, perhaps containing many candidates for describing real world physics, and present the arguments for and against this idea. We discuss statistical surveys of the landscape, and the prospects for testable consequences of this picture, such as observable effects of moduli, constraints on early cosmology, and predictions for the scale of supersymmetry breaking.

Notes on superconformal Chern-Simons-Matter theories (2007, background): “More ambitiously, one may wonder if there are connections of the CS-matter theories to the vast number of AdS4 string vacua in flux compactifications (see for example [45]).”
Tate’s algorithm and F-theory (2011, background): “Moreover, Ftheory has played an important rôle in the study of the “landscape” of string compactifications, both in four dimensions [12, 13, 14] and in recent work in six dimensions [15, 16, 17, 18].”
Inflationary Constraints on Type IIA String Theory (2007, background): “Secondly, there are an exponentially large number of potential energy functions, parameterized by typically hundreds of discrete fluxes in the compact space [11, 12, 13, 14, 15].”

A polynomial f(R) inflation model (2013, background): “On the other hand, from the viewpoint of an ultraviolet(UV) complete quantum theory of gravity, for example the string theory, α′ = 1/M2 s corrections to the Einstein-Hilbert action are always expected [7–9], i.”
The effective theory of type IIA AdS4 compactifications on nilmanifolds and cosets (2008, methodology): “Motivated by this and other applications, the derivation of the four-dimensional (4D) low-energy effective actions of flux compactifications has been an active area of research during the past decade (for reviews and a more complete list of references, see, e.g., [1–3]).”
Non-Thermal Dark Matter and the Moduli Problem in String Frameworks (2008, background): “These frameworks are also attractive in the sense that they provide a mechanism for supersymmetry breaking at low scales (∼ TeV), thus accommodating the hierarchy between the Electroweak and Planck scales (see [26–28] for reviews).”
Systematics of string loop corrections in type IIB Calabi-Yau flux compactifications (2007, methodology): “2 Case 2: CP 4 [1,1,1,6,9] We next consider loop corrections to the Kähler potential for the Calabi-Yau orientifold CP 4 [1,1,1,6,9].”
