In summary, the conversation discusses interesting descriptions of various subjects, such as string theory and general relativity, found on the website http://www.theory.caltech.edu/people/patricia/index.html. The conversation also mentions a specific page, http://www.theory.caltech.edu/people/patricia/test/Einstein33.html, which discusses solving Einstein's equations in three dimensions. There is also a mention of a quote about Archimedes' rule and the Pythagorean theorem being attributed to the wrong person.

Short but interesting descriptions of several subjects, e.g. string theory and general relativity.

Are you talking about the page that says:
For example, Archimedes' rule tells us that the length of the hypotenuse of a right triangle equals the sum of the squares of two sides. That rule actually defines a space metric called the "flat" metric or the "Euclidean metric" in two space dimensions.

'Interesting' is all I can say.

Where'd you see that quote? The pages I skimmed attributed the pythagorean theorem to Pythagoras.

You go to 'Theoretical Physics Fun', then 'Solve The Einstein Equations Yourself', then 'Solving Einstein's Equation in Three Dimensions', then 'What Is the Spacetime Geometry?', then 'A Few key concepts for the brave.

In other words, http://www.theory.caltech.edu/people/patricia/test/Einstein33.html [Broken].

And do note not only the pfact the theorem is attributed to the wrong person, but what it actually says here... I myself have never seen THIS in action: 'hypotenuse of a right triangle equals the sum of the squares of two sides'.

1) What is string theory?

String theory is a theoretical framework in physics that attempts to explain the fundamental nature of particles and their interactions by modeling them as tiny, vibrating strings instead of point-like particles.

2) How does string theory relate to general relativity?

String theory incorporates the principles of general relativity, which is a theory of gravity that describes how massive objects interact with each other. String theory provides a deeper understanding of gravity by incorporating the other fundamental forces of nature (electromagnetism, strong nuclear force, and weak nuclear force) into its framework.

3) What is the significance of Caltech in relation to string theory and general relativity?

Caltech is a leading institution in the study of string theory and general relativity. Many influential physicists, such as Albert Einstein and Richard Feynman, have been associated with Caltech, and the school continues to be at the forefront of research in these areas.

4) How does string theory impact our understanding of the universe?

String theory has the potential to provide a unified framework for understanding all of the fundamental forces and particles in the universe. It also has implications for cosmology, as it may help explain the origins and evolution of the universe.

5) What are some current research topics in string theory and general relativity at Caltech?

Some current research topics at Caltech include the holographic principle, black holes, and the connection between string theory and quantum mechanics. Caltech also has ongoing collaborations with other institutions to further explore the implications of string theory and general relativity.
