The Trouble With Physics
''The Trouble with Physics: The Rise of String Theory, the Fall of a Science, and What Comes Next'' is a 2006 book by the theoretical physicist Lee Smolin about the problems with string theory. The book strongly criticizes string theory and its prominence in contemporary theoretical physics, on the grounds that string theory has yet to come up with a single prediction that can be verified using any technology that is likely to be feasible within our lifetimes. Smolin also focuses on the difficulties faced by research in quantum gravity, and by current efforts to come up with a theory explaining all four fundamental interactions. The book is broadly concerned with the role of controversy and diversity of approaches in scientific processes and ethics. Smolin suggests both that there appear to be serious deficiencies in string theory and that string theory has an unhealthy near-monopoly on fundamental physics in the United States, and that a diversity of approaches is needed. He arg ...

Lee Smolin
Lee Smolin (; born June 6, 1955) is an American theoretical physicist, a faculty member at the Perimeter Institute for Theoretical Physics, an adjunct professor of physics at the University of Waterloo, and a member of the graduate faculty of the philosophy department at the University of Toronto. Smolin's 2006 book ''The Trouble with Physics'' criticized string theory as a viable scientific theory. He has made contributions to quantum gravity theory, in particular the approach known as loop quantum gravity. He advocates that the two primary approaches to quantum gravity, loop quantum gravity and string theory, can be reconciled as different aspects of the same underlying theory. He also advocates an alternative view on space and time that he calls temporal naturalism. His research interests also include Physical cosmology, cosmology, elementary particle theory, the foundations of quantum mechanics, and theoretical biology.

Sean M
Sean, also spelled Seán or Séan in Hiberno-English, is a male given name of Irish origin. It comes from the Irish versions of the Biblical Hebrew name ''Yohanan'' (), Seán (anglicized as '' Shaun/ Shawn/ Shon'') and Séan (Ulster variant; anglicized ''Shane/Shayne''), rendered '' John'' in English and Johannes/Johann/Johan in other Germanic languages. The Norman French ''Jehan'' (see '' Jean'') is another version. In the Irish language, the presence and placement of the síneadh fada is significant, as it changes the meaning of the name. The word "Sean" in Irish means "old", while the word "Séan" means "omen". For notable people named Sean, refer to List of people named Sean. Origin The name was adopted into the Irish language most likely from ''Jean'', the French variant of the Hebrew name ''Yohanan''. As Irish has no letter (derived from ; English also lacked until the late 17th Century, with ''John'' previously been spelt ''Iohn'') so it is substituted by , as was the ...

The Elegant Universe
''The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory'' is a book by Brian Greene published in 1999, which introduces string and superstring theory, and provides a comprehensive though non-technical assessment of the theory and some of its shortcomings. In 2000, it won the Royal Society Prize for Science Books and was a finalist for the Pulitzer Prize for General Nonfiction. A new edition was released in 2003, with an updated preface. Summary Part I: The Edge of Knowledge Chapter 1, "Tied Up With String", briefly introduces the conflicts between our current theories, and how they may be resolved. He introduces the building blocks of matter, electrons and quarks, and the forces that govern them. Part II: The Dilemma of Space, Time, and the Quantum Chapter 2, "Space, Time, and the Eye of the Beholder" explains Albert Einstein's special relativity, which united James Clerk Maxwell's electrodynamics with Galileo's principle of relativit ...

Brian Greene
Brian Randolph Greene (born February 9, 1963) is an American physicist known for his research on string theory. He is a professor of physics and mathematics at Columbia University, director of its center for theoretical physics, and the chairman of the World Science Festival, which he co-founded in 2008. Greene co-discovered mirror symmetry, relating two different Calabi–Yau manifolds. He also described the flop transition, a mild form of topology change, and the conifold transition, a more severe transformation of space, showing that topology can smoothly change in string theory. His books '' The Elegant Universe (1999)'', '' The Fabric of the Cosmos (2004)'', '' The Hidden Reality (2011)'', and ''Until the End of Time'' (2020) were all top 10 New York Times bestsellers. Greene hosted two Emmy and Peabody Award Winning NOVA miniseries based on his books. He also appeared on '' The Big Bang Theory'' episode " The Herb Garden Germination", as well as in the films '' ...

Loop Quantum Gravity
Loop quantum gravity (LQG) is a theory of quantum gravity that incorporates matter of the Standard Model into the framework established for the intrinsic quantum gravity case. It is an attempt to develop a quantum theory of gravity based directly on Albert Einstein's geometric formulation rather than the treatment of gravity as a mysterious mechanism (force). As a theory, LQG postulates that the structure of space and time is composed of finite loops woven into an extremely fine fabric or network. These networks of loops are called spin networks. The evolution of a spin network, or spin foam, has a scale on the order of a Planck length, approximately 10−35 meters, and smaller scales are meaningless. Consequently, not just matter, but space itself, prefers an atomic structure. The areas of research, which involve about 30 research groups worldwide, share the basic physical assumptions and the mathematical description of quantum space. Research has evolved in two directions ...

JPEG
JPEG ( , short for Joint Photographic Experts Group and sometimes retroactively referred to as JPEG 1) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable trade off between storage size and image quality. JPEG typically achieves 10:1 compression with noticeable, but widely agreed to be acceptable perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The Joint Photographic Experts Group created the standard in 1992, based on the discrete cosine transform (DCT) algorithm. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet and later social media. JPEG compression is used in a number of ...

Synchronized Multimedia Integration Language
Synchronized Multimedia Integration Language (SMIL ()) is a World Wide Web Consortium recommended Extensible Markup Language (XML) markup language to describe multimedia presentations. It defines markup for timing, layout, animations, visual transitions, and media embedding, among other things. SMIL allows presenting media items such as text, images, video, audio, links to other SMIL presentations, and files from multiple web servers. SMIL markup is written in XML, and has similarities to HTML. Members of the World Wide Web Consortium (also known as the "W3C") created SMIL for streaming media presentations, and published SMIL 1.0 in June 1998. Many of these W3C members helped author several versions of SMIL specifications between 1996 (when the first multimedia workshops were hosted by the W3C) and 2008 (when SMIL 3.0 was published). SMIL is an XML-based application, and is a part of many Multimedia Messaging Service (MMS) applications. SMIL can be combined with other XML-bas ...
