IESO Astronomy Problems (2007-2013)

IESO, or International Earth Science Olympiad contains one section of terrestrial astronomy. In the previous years, some similar problems from IESO appeared in the National Astronomy Olympiad. In this collection, I've compiled all the astronomy problems from past IESOs. Hope this will be a useful resource for astronomy olympiad preparation. 

British Physics Olympiad (BPhO)

British Physics Olympiad website contains a selection of BPhO questions by topic area, past papers and important notes to upgrade physics problem solving skills. Here you'll find sample problems ranging from astronomy to particle physics. It's a really good resource for physics olympiad preparation. 

Isaac Physics

Isaac Physics is a MOOC (Massive Open Online Course) to develop problem solving skills in Physics, developed by University of Cambridge. It's a good preparation tool for physics olympiad.  It has levels 1-6. Have a look to find out your level and increase your physics problem solving skill.

International Chemistry Olympiad Problems (1968-2014)

The International Chemistry Olympiad (IChO) is an annual academic competition for high school students. It is one of the International Science OlympiadsThe first IChO was held in Prague, Czechoslovakia, in 1968. The event has been held every year since then, with the exception of 1971. Here are the problems and solutions of every single International Chemistry Olympiads from 1968 to 2014.

IAO Problems (2011-2014)

The International Astronomy Olympiad was founded by Eurasian Astronomical Society in 1996. The competing part of IAO consists of three rounds: a theoretical, an observational, and a practical. Problems of the theoretical round involve classical problems in branches of astronomy, astrophysics, space and planetary physics, and maybe hypothetical situations. The observational round involves recognizing stars, constellations, estimating star magnitude and angular distance, working with telescopes or other observational technique. The practical round consists of problems based on data results of observations, solutions propose analysis of these data. Here are the problems of IAO, some are really old and some of the papers are latest. Enjoy!

Astronomical Olympiads - V. G. Surdin

The book contains about 400 problems in astronomy. Some of them - classical, part - totally new. All decisions drawn up by the author of the book, and often complement and even correct the mistakes of classical solutions. The level of problems in the Olympiad are below average, although some challenges will require hard work. The vast majority of problems with a twist '`Do not rush to respond, even if at first glance seem a simple task. The book is highly recommended for students who are preparing for astronomy Olympiad.

Equatorial Mount

An equatorial mount is a mount for instruments that follows the rotation of the sky (celestial sphere) by having one rotational axis parallel to the Earth's axis of rotation. This type of mount is used for astronomical telescopes and cameras. The advantage of an equatorial mount lies in its ability to allow the instrument attached to it to stay fixed on any object in the sky that has a diurnal motion by driving one axis at a constant speed. Such an arrangement is called a sidereal drive.
