Thus, string theory is a theory of quantum gravity. String theory is a broad and varied subject that attempts to address a number of deep questions of fundamental physics.
What scientist studies string theory?
String theory is a framework that physicists use to describe how forces usually conceptualized on a gigantic level, like gravity, could affect tiny objects like electrons and protons. In Albert Einstein’s theory of general relativity, gravity is a force that warps space-time around massive objects.
Can you be a theoretical chemist?
Theoretical chemists investigate theoretical methods that can predict the outcomes of chemical experiments. Theoretical chemistry encompasses a variety of specializations, although most specializations incorporate advanced computation and programming.
What branch of physics is string theory?
string theory, in particle physics, a theory that attempts to merge quantum mechanics with Albert Einstein’s general theory of relativity.
What math do I need for string theory?
String theory usually builds on this with at the very least a little algebraic geometry. If you take cues from people on the nLab, category theory can be big in string theory. Pick any combination of differential/algebraic and geometry/topology and it will be useful in string theory.
Who is the best string theorist?
Gabriele Veneziano. Italian theoretical physicist and string theorist. His 1968 dual resonance model of the strong interaction was the first string theory to be discovered, and thus he is regarded as a founder of the field.
Will string theory ever be solved?
Because string theory has near-miraculous breakthroughs every 8 to 10 years, we can expect 2 more breakthroughs in the theory before 2020, and hence might be able to solve this theory by then.
Has string theory been disproved?
No one has proved the swampland conjecture, and several string theorists still expect that the final form of the theory will have no problem with inflation. But many believe that although the conjecture might not hold up rigidly, something close to it will.
Is string theory still used?
And today, that string theory also remains, still attempting to explain the strong force — and so much more.
Is chemistry real or a theory?
Even though chemistry is more like an applied science and often relies on models rather than on pure theories, one can envision fundamental theories that would fall under Popper’s narrow definition that can only or principally be falsified by organic chemists.
Can you do chemistry without a lab?
Many researchers do no traditional lab experiments. Computational chemistry is important and a huge subject. The mathematical theory of chemistry is the Schrödinger equation, known since over 70 years, but unfortunately too difficult to solve for most molecules with more than a few atoms.
Is theoretical chemistry useful?
Theoretical chemistry provides ongoing experiments with new insights and allows one to study molecular systems in the absence of experiment.
Who is the father of string theory?
Leonard Susskind, a physicist at Stanford University, is a founding father of string theory. Students recently had a Skype conversation with this 78 year old physics legend. You were a plumber before you studied physics.
Is string theory hard to understand?
It is very very tough. Anyone interested in String Theory needs to think very very hard on what they want to do with themselves. They need to get a String Theory textbook and work through it, every problem, however long it takes.
How much does a theoretical physicist make?
Salary Ranges for Theoretical Physicists The salaries of Theoretical Physicists in the US range from $55,610 to $185,230 , with a median salary of $98,391 . The middle 50% of Theoretical Physicists makes between $84,902 and $98,390, with the top 83% making $185,230.
What should I study before string theory?
First try to learn advanced mathematics like Calculus, Linear Algebra, complex analysis etc along with advanced physics. Learn Quantum Mechanics and Relativity(you need to be adept in it as though it is the back of your hand). Then slowly watch intro videos on String theory, understand them thoroughly.
How do you become a string theorist?
Getting a Ph. If you are interested in string theory as a long-term career, then you are aiming to become a physics professor researching and teaching in a university – which is where [almost] all string theorists work. This always requires a Ph. D. The trek to academic string theory as a profession is not an easy one.
What are the 11 dimensions in string theory?
What is 11th dimension? The 11th dimension is a characteristic of space-time that has been proposed as a possible answer to questions that arise in superstring theory. The theory of superstrings involves the existence of nine dimensions of space and one dimension of time for a total of 10 dimensions.
Who is the smartest physicist alive today?
Edward Witten: Best known for his work on string theory, M-theory, quantum gravity and supersymmetry, Witten, a Baltimore native, is considered the world’s greatest living theoretical physicist, making Time 100’s most influential people in the world list in 2004.
Who is the smartest physicist in the world?
Albert Einstein Einstein, who took US citizenship in 1940, also provided the world with its most famous equation, E=mc2, which demonstrates the equivalence of mass and energy. His name has become synonymous with the idea of genius and he died a celebrity. He was awarded the 1921 Nobel prize for physics.
Who is the top physicists in the world today?

How many universes does string theory predict?
Each compactification produces a different spacetime, meaning that string theory can realistically predict a multiverse populated by 10^500 different universes.
What are the 26 dimensions?
The 26 dimensions of Closed Unoriented Bosonic String Theory are interpreted as the 26 dimensions of the traceless Jordan algebra J3(O)o of 3×3 Octonionic matrices, with each of the 3 Octonionic dimenisons of J3(O)o having the following physical interpretation: 4-dimensional physical spacetime plus 4-dimensional …
What is the opposite of string theory?
JB: Loop quantum gravity is an alternative to string theory, which in its earliest formulation says that particles are composed of one-dimensional lines or strings of energy. Different particles, in this theory, represent different vibrational patterns in these strings.
How likely is string theory correct?
Polchinski explained a computation that shows that string theory is 98.5% likely to be correct, going on to claim that the probability is actually higher: “something over 3 sigma” (i.e. over 99.7%).
