...Sanders concert, to be broadcast locally on August 15 by WGBH-TV, will include works by Schuts, Byrd, Janequin, Barber and Bach. The Chorus, under the direction of Iva Dee Hiatt, associate Josquin, this concert will be sung on professor of Music and director of choral music at Smith College, will be accompanied by a chamber orchestra drawn from the Cambridge Civic Symphony...
...said that during rehearsals conductor Iva Dee Hiatt (of Smith College) called forth this attitude by fervent references to her home institution and its undergraduates' most exuberant moments (an invitation from Yale, etc.). Whatever the merits of these tactics, there can be little doubt that Miss Hiatt is an effective conductor. Under her direction, the Chorus marched through the evening with a most un-amateur precision; attacks were sharp and clear, the tone clear and even...
...working like a Swiss watch right now." That, last week, was the judgment of a top member of the team that developed the Navy's navigation satellite Transit IVA. Following three earlier Transits that suffered from minor but decisive bugs (e.g., a burst battery), Transit IVA, launched last fortnight, is doing its electronic job better than anyone had hoped. Though planned as an experimental model, it will become a regular part of the navigation-satellite system if it continues to work well...
...Transit IVA, which was built for the Bureau of Naval Weapons by the Applied Physics Laboratory of Johns Hopkins University, is the Navy's fourth and most significant step toward establishing a system of satellites from which ships and airplanes can determine their position anywhere on earth (TIME, April 25, 1960). None of the earlier transits worked very well, but the first signals from Transit IVA promise that it will do far better...
Most interesting improvement on Transit IVA is its nuclear power supply, built for the Atomic Energy Commission by the Martin Co. Tucked under Transit's big drum is a 5-in. white metal ball surrounding a pellet of plutonium 238*, a rare isotope of plutonium that gives off enough alpha radiation to heat itself as it decays. Thermocouples transform this ever-renewed heat into 2.7 watts of electricity for two of Transit's four transmitters. The little generator weighs only 4.6 lbs., but its plutonium fuel, with a half life of 90 years, is expected to supply power...
