		This construction demonstrated that string theory not only reconciles quantum mechanics and gravity, but can also contain within it electrons, protons, photons and all the other observed particles and forces, and hence is a viable candidate for a complete unified theory of nature.
		In 1991 Strominger co-discovered the brane solutions of string theory, which have played a crucial role in unraveling the beautiful mathematical structure and duality symmetries of the theory

	Conifold - Wikipedia, the free encyclopedia
		In the context of string theory, the geometrically singular conifolds were shown to lead to completely smooth physics of strings.
		The divergences are "smeared out" by D3-branes wrapped on the shrinking three-sphere, as originally pointed out by Andrew Strominger.
		Andrew Strominger together with Dave Morrison and Brian Greene have also found that the topology near the conifold singularity can undergo a topology transition.

	Black Holes and Beyond: Harvard’s Andrew Strominger on String Theory
		Among the hottest physicists driving the string theory revolution is Harvard University's Andrew Strominger, who over the past five years has led the way in merging the study of quantum-mechanical fl holes–a pursuit popularized by Cambridge University's Stephen Hawking–with that of string theory to advance understanding in both fields.
		Strominger spent the next five years at the Institute for Advanced Study in Princeton before joining the faculty of the University of California at Santa Barbara.
		Strominger: The problem we set out to solve is that of understanding the Bekenstein-Hawking entropy, named for Jacob Bekenstein and Stephen Hawking.

	String Theory, Black Holes, and the Fundamental Laws of Nature \| Dr. Andrew Strominger
		In 1991 Strominger co-discovered the brane solutions of string theory, which have played a crucial role in unraveling the beautiful mathematical structure and duality symmetries of the theory [2].
		The branes were eventually used by Strominger and collaborators to give a microscopic explanation of how fl holes are able to store information [3]; finally resolving a deep paradox uncovered by Hawking and Bekenstein a quarter century earlier.
		He and coworkers also used the branes to derive new relations in algebraic geometry, equating the moduli space of a brane in a Calabi-Yau space to the mirror Calabi-Yau [4].

		Andrew Strominger, a leading string theorist based at the Harvard University, US, who is on a brief visit to Calcutta.
		According to Strominger, string theory is viewed as the final theory of Nature — “the -a-s-t step in the path that beg an with Aristotle and Plato.” But he thinks that is implausible.
		To move forward, Strominger argues, the string theorists should work on the problems that they are able to make a progress on.

	Superstrings
		Strominger and Vafa confirmed a result derived by Jacob Bekenstein and Stephen Hawking back in the late 1970's.
		This was a surprising result, since no one could understand (and nor did the computations give any insight) how an object as simple as a fl hole (which can be characterized simply by its mass and its spin) could have such a large amount of disorder within it.
		As a result of building this special fl hole using string theory, Strominger and Vafa were able to obtain the correct value for the disorder predicted by Bekenstein and Hawking.

	Twenty years of string theory
		Andrew Strominger, a Professor of Physics at Harvard University, United States, is a leading scientist in string theory research.
		Strominger also provided an interesting glimpse of the blend of differing moods - of adventure and excitement at the unexpected advance of the theory, of caution over unsolved problems and of optimism based on experience - that characterise fundamental science in the making.
		Strominger, 20 years after the dramatic result of Michael Green and John Schwarz in 1984, which set off what string theorists like to call the first revolution in string theory, to what extent has the initial promise of string theory been realised?

		At about the same time physicist Andrew Strominger discovered that a certain type of fl hole, what he calls a "charged extremal fl hole," could solve a similar problem encountered in string theory.
		Strominger, Greene, and Morrison had just shown how several thousand different string theories operating in four, five, six, and even ten spatial dimensions could all be united with perfect consistency into just one theory, the ten-dimensional one.
		Strominger discovered that in six spatial dimensions, the mass of an "extremal" fl hole (one with a mass and charge so tiny as to be comparable to one of the fundamental particles) is proportional to its surface area.

	String Duality
		Strominger, Greene and David R. Morrison of Duke University found that fl holes help to connect perhaps thousands of the tens of thousands of solutions to string theory in a complex web.
		Strominger was investigating how extremal fl holes behave when a dimension of space-time curls up very tight.
		Moreover, Greene, Morrison and Andrew Strominger of the University of California at Santa Barbara have shown that quantum effects make it possi- ble for spaces with different numbers of holes-such as a doughnut and a sphere - to transform smoothly into one another, a no-no for mathematicians.

	Hawking's Breakthrough Is Still an Enigma
		Black holes are the prima donnas of Einstein's general theory of relativity, which explains the force known as gravity as a warp in space-time caused by matter and energy.
		In this theory, a fl hole is a tangled mélange of strings and multidimensional membranes known as "D-branes." In a virtuoso calculation in 1995, Dr. Strominger and Dr. Cumrun Vafa, also of Harvard, untangled the innards of an "extremal" fl hole, in which electrical charge just balanced gravity.
		Perhaps the most mysterious and far-reaching consequence of the exploding fl hole is the idea that the universe can be compared to a hologram, in which information for a three-dimensional image can be stored on a flat surface, like an image on a bank card.

	S-branes - Wikipedia, the free encyclopedia
		S-branes are space-like branes, hypothetical objects (or configurations) in string theory that are localized in the temporal direction, but otherwise analogous to P-branes.
		S-branes were originally proposed by Andrew Strominger in his speculative paper with Michael Gutperle, and another version of S-branes was studied by Ashoke Sen.
		"S" stands for "Strominger", "Sen", or "Spacelike", depending on the context.

		With the answer to the fl hole riddle, scientists will be better equipped to solve one of the most challenging problems in all of physics: tying together quantum theory, which rules the domain of the very small, and general relativity, the highly successful theory of gravity developed by Albert Einstein in 1915.
		To help solve the fl hole–information conundrum, Strominger and other physicists are turning to a branch of quantum theory known as string theory.
		Strominger and Cumrun Vafa of Harvard have used string theory to calculate the entropy of a fl hole, a measure of its information content.

		Andrew Strominger of Harvard pointed out that Einstein himself modified relativity in 1915, when he brought gravity into the picture with his general theory of relativity.
		Special relativity, as the 1905 theory became known, is only strictly valid in flat space without gravity, Dr. Strominger said.
		He added, "It is natural to think that Einstein's relativity will in some sense be violated by small corrections, just as Newton's theory of gravity has small corrections." These corrections did not make Newton wrong, he said, they just meant his theory was not always perfectly applicable.

		In 1990 Andrew Strominger of the Institute for Theoretical Physics in Santa Barbara found that a 1 0-dimensional string can yield a soliton that is a five-brane.
		Reviving an earlier conjecture of mine, Strominger suggested that a strongly interacting string is the dual equivalent of weakly interacting five-branes.
		The technology of Dirichlet-branes has now enabled Strominger and Cumrun Vafa of Harvard University to count the number of quantum states in flbranes.
