We discuss three separate types of infinities that occur in non-supersymmetric canonical gravity and string theory. We consider UV perturbative singularities in non-supersymmetric gravity coupled to matter and how these are related to loop corrections to beta functions for non-supersymmetric strings. Nex...

We have some candidates for the constructive definition of string theory based on ten dimensional super Yang-Mills theory reduced to various dimensions. Although there are some evidences that these models describe gravity, the way how the diffeomorphism invariance is realized is not clear. In this ...
nullis the only primitive value that is “falsy” (aka false-like; seeChapter 4) but which also returns"object"from thetypeofcheck. So what’s the seventh string value thattypeofcan return? typeoffunctiona(){/* .. */}==="function";// true ...
Types of Instruments Many different instruments are found in Asia, but string instruments are among the most popular. Traditionally, in ancient China, instruments were categorized by the materials they were made from. The eight material categories for instruments were hide, clay, metal, stone, gou...
In Java, you must explicitly declare the type of every variable, as shown below: int x = 10; // Integer double y = 10.5; // Float String z = "Hello"; // String Powered By In contrast, Python allows you to assign values directly without specifying the type, making it more flexible...
Explore the intersection of religion and other fields in today's world. For example, you might delve deeper into the lesson's example of religion and string theory, or read a study on religion and chaos theory in mathematics, or how religion affects mental health. Religious Beliefs Today: ...
There has been an increasing interest in the Spinc(n) groups ever since the publication of the Seiberg–Witten equations for 4-manifolds [58], whose formulation requires the existence of Spinc(n)-structures, and more recently for the role they play in string theory [6, 13, 44]. In ...
A cell, in biology, is the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell may be a complete organism in itself, such as a bacterium, or it may acquire a specialized fun
Landscape Multiverse(Level 1 & 4): String theory leaves open a lot of different fundamental properties of the universe which, combined with the inflationary multiverse, means there could be many bubble universes out there which have fundamentally different physical laws than the universe we inhabit. ...
