The inclination of the earth\u27s equatorial plane to the plane of the earth\u27s orbit around the sun, termed the obliquity of the ecliptic by astronomer\u27s, is approximately equal to 23º27\u27 of arc. If this inclination were 0º the sun would remain directly overhead the Equator throughout the year and there would be no seasons. In reality, the directly overhead point of the sun moves north and south with the seasons

Symmetry - Ytremmys

A crossword puzzle should be symmetrical. The diagram on the following page certainly is -- even though it looks more like a maze than a crossword puzzle

Leapin\u27 Lizards -- L.O. Annie

Have you ever wondered about the credited quotes in Webster\u27s Third New International Dictionary? Webster\u27s assures us they are contemporary quotations from well-known people and publications. Close examination of the dictionary itself, however, reveals they are a bewildering diversity, not necessarily either contemporary or well-known

Optical Quantum Computation

We review the field of Optical Quantum Computation, considering the various implementations that have been proposed and the experimental progress that has been made toward realizing them. We examine both linear and nonlinear approaches and both particle and field encodings. In particular we discuss the prospects for large scale optical quantum computing in terms of the most promising physical architectures and the technical requirements for realizing them

Applications of W-algebras to BF theories, QCD and 4D Gravity

We are able to show that BF theories naturally emerge from the coadjoint orbits of $W_2$ and $w_\infty$ algebras which includes a Kac-Moody sector. Since QCD strings can be identified with a BF theory, we are able to show a relationship between the orbits and monopole-string solutions of QCD. Furthermore, we observe that when 4D gravitation is cast into a BF form through the use of Ashtekar variables, we are able to get order $\hbar$ contributions to gravity which can be associated with the $W_2$ anomaly. We comment on the relationship to gravitational monopoles.Comment: 14 page
