The Earth’s atmosphere, the thin envelope of air that surrounds our planet, consists of a mixture of gases, extending from the surface of the Earth to the edge of space and tied to the Earth mainly by its gravitational force, and partly by the magnetic field at high altitude. It comprises mainly molecular nitrogen (78% in mass) and molecular oxygen (21%), with the other 1% composed of trace …
This is a “minimalist” textbook for a first semester of university, calculus-based physics, covering classical mechanics (including one chapter on mechanical waves, but excluding fluids), plus a brief introduction to thermodynamics. The presentation owes much to Mazur’s The Principles and Practice of Physics: conservation laws, momentum and energy, are introduced before forces, and one-di…
The research presented here includes important contributions on the commissioning of the ATLAS experiment and the discovery of the Higgs boson. The thesis describes essential work on the alignment of the inner tracker during the commissioning of the experiment and development of the electron identification algorithm. The subsequent analysis focuses on the search for the Higgs boson in the WW ch…
This collection of science fiction writings by Jayant V. Narlikar offers readers a unique glimpse into the world-famous Indian astrophysicist’s vivid and highly imaginative concepts and stories.

Including considerations of sustainability in universities’ activities has long since become mainstream. However, there is still much to be done with regard to the full integration of sustainability thinking into science and engineering curricula. Among the problems that hinder progress in this field, the lack of sound information on how to actually implement it is prominent. Created in order…

Sir Patrick Moore, dalam benak banyak orang, adalah astronom paling terkenal di abad kedua puluh. Hal ini terutama berlaku di Inggris Raya, di mana serial televisinya di BBC, The Sky at Night, wajib ditonton oleh para astronom amatir, dan bahkan banyak astronom profesional. Kecintaannya pada subjek dan kegembiraan yang dia promosikan sangat melegenda. Sayangnya, dia meninggal pada bulan Desembe…
Written by William Sheehan, a noted historian of astronomy, and Christopher J. Conselice, a professional astronomer specializing in galaxies in the early universe, this book tells the story of how astronomers have pieced together what is known about the vast and complicated systems of stars and dust known as galaxies. The first galaxies appeared as violently disturbed exotic objects when the…
