Students and research workers in mathematics, physics, engineering and other sciences will find this compilation of more than 2000 mathematical formulas and tables invaluable. They will see quickly why half a million copies were sold of the first edition! All the information included is practical – rarely used results are excluded. Topics range from elementary to advanced-from algebra, trigonometry and calculus to vector analysis, Bessel functions, Legendre polynomials and elliptic integrals. Great care has been taken to present all results concisely and clearly. Excellent to keep as a handy reference!
Night Ark is a group that draws from so many fields of music it proves difficult to label. Many (but not all) of the instruments featured on this release originated in the Middle East; leader Ara Dinkjian's specialty is the oud, but he also occasionally plays guitar and piano, along with the less-familiar canoon and cumbus. The music includes exotic originals by the group, each of which merits repeated listening.
