This observation is often taken as the starting point of twistor theory.

It's much more directly related to observation than twistor theory, which is mathematical.

He is optimistic about his own approach, twistor theory.

Twistor theory also seemed unrelated to ideas in mainstream physics.

The Penrose transform is a major component of classical twistor theory.

This is standard in twistor theory and supersymmetry.

The Hopf fibration is important in twistor theory.

For many years after Penrose's foundational 1967 paper, twistor theory progressed slowly, in part because of mathematical challenges.

While twistor theory appeared to say something about quantum gravity, its potential contributions to understanding the other fundamental interactions and particle physics were less obvious.

The first is twistor theory, and more specifically, in developing its relation to Einstein's general relativity, which I think is key.

My point in the book will be that twistor theory certainly hasn't solved some of the problems that I thought it would, but it's very much alive.

(One fruitful method uses twistor theory.)

To simplify this process ideas from twistor theory are often used which enables one to decompose a null-vector into a pair of spinors.

Twistor theory was first proposed by Roger Penrose in 1967, as a possible path to a theory of quantum gravity.

Since the early 1970s, Hodges has worked on twistor theory which is the approach to the problems of fundamental physics pioneered by Roger Penrose.

If twistor theory can incorporate general relativity then it will give leads on how to unite general relativity with quantum theory.

The unitary and special unitary holonomies are often studied in connection with twistor theory, as well as in the study of almost complex structures.

In 1967, Penrose invented the twistor theory which maps geometric objects in Minkowski space into the 4-dimensional complex space with the metric signature (2,2).

There are many methods for constructing gravitational instantons, including the Gibbons-Hawking Ansatz, twistor theory, and the hyperkähler quotient construction.

Twistor theory is unique to 4D Minkowski space and the (2,2) metric signature, and does not generalize to other dimensions or metric signatures.

Twistor theory-" "Ancestor worship," scoffed Spry.

Jozsa received his DPhil in Mathematics (specifically, twistor theory) at Oxford, under the supervision of Roger Penrose.

He is most famous for his extension of Roger Penrose's twistor theory to nonlinear cases (Roger Penrose was Richard Ward's supervisor at university).

A discussion of the measurement problem in quantum mechanics is given a full chapter; superstrings are given a chapter near the end of the book, as are loop gravity and twistor theory.

In theoretical and mathematical physics, twistor theory maps the geometric objects of conventional 3+1 space-time (Minkowski space) into geometric objects in a 4 dimensional space with metric signature (2,2).
