Abstract: This film provided by the British Information Service details the developmental history of marine radar The creation of a plan position indicator PPI or radar output display made shipborne radar possible In 1946 the minimum requirements for radar equipment were established at an international meeting in London A year later the international standard for marine radar built to withstand seagoing conditions was set This navigational aid saves time money and often lives A ship entering the harbor of St John New Brunswick Canada is shown using radar to navigate in the fog Title from label on videocassette

Abstract: Lynn Poole announces that on July 1 1954 Mars will be closer to the earth than in the past 15 years He then explains the words Mars March and Tuesday originated from Mars the Roman god of war and the days of the week were the seven wanderers or planets in Greek in the sky He describes the location of Mars and compares its relative size and distance from other planets using a football field model and the length of an imaginary plane flight Telescopic views of Mars are unclear and photographs are difficult to make however polar caps have been seen and their changing size suggests seasons on the planet The Dutch astronomer Christian Huyghens sketched Mars with continents and oceans but his view has been disproved In 1877 Italian astronomer Schiaparelli noted lines which he called canali or canals on the surface of Mars So far oxygen has been undetected on the planet but a life form such as lichen a fungus and algae combination might be possible there

Abstract: Lynn Poole displays and discusses various symbols including the skull and crossbones horseshoe swastika barber pole cigar store Indian mortar and pestle and chevron Words can be symbols also Latin although not spoken today as a living language is still used in scientific communication Latin began as the language of Rome and its vicinity but through many conquests the Romans spread the use of Latin to the rest of Italy and what is now France Spain and North Africa The Romans also conquered Greece but since Green was also a highly developed literary language the Greeks retained their own language Latin also became the language of the Roman Catholic Church and medieval universities Many scientific discoveries made during the Renaissance and the early modern period were given names in Latin Even today Latin names such as Zea mays corn are used in scientific communication Carl von Linné or Carolus Linneaus in Latin classified life forms in an orderly way using Latin terms In his classification of kingdom phylum class order family genus and species a dog would be animal chordata mammalia carnivora canidae canis familiarus The Babylonians were fond of the number 60 which is retained today in 60 seconds in a minute and 60 minutes in an hour and even 360 degrees in a circle which is 6 times 60 Weights and measures have been standardized so that they mean the same thing all over the world

Abstract: This program focuses on the scientific achievements of four U S universities At Indiana University Vaclav Hlavaty solved the differential equations of unified gravitational and electromagnetic field thus providing proof for Einsteins unified field theory Erwin Schrodinger and Karl Schwarzschild pioneers in this research are also discussed From the New York University Dr Serge A Korff directed a study of the effects of cosmic radiation from a high altitude observatory built on Mt Wrangell in Alaska His plane pilot was Dr Terris Moore president of the University of Alaska University of Pittsburghs Dr Buchsbaum professor of zoology worked with colleagues to research how cells bathed in a nutrient fluid react to drugs and disease A film shows these cell reactions under a phasecontrast microscope Under the direction of Henry J Gomberg William Kerr assistant director of the Michigan Memorial Phoenix Project and assistant professor of electrical engineering at the University of Michigan are investigating peaceful uses of atomic energy They have developed a beta ray microscope that uses radioactive isotopes as tracers in specimens under microscopic investigation This allows them to see how atoms are distributed in alloys and tracing the path of carbon in plants

Abstract: Lynn Poole announces that the current issue of TV Stage has an article about The Johns Hopkins Science Review A film by the US Dept of Interior then shows the historical use of the Colorado River In the late 1800s Thomas Blythe acquired 40000 acres in Palo Verde Valley California and filed the first water rights to the river In 1867 Jack Swilling built the first irrigation canals in Arizona By diverting water from the river to land the southwest began to thrive However floods such as the one that created Salton Sea in 1905 alternating with droughts required a plan to stabilize the flow of the Colorado Arthur Powell Davis Director of the U S Reclamation Service proposed a dam and the Boulder Canyon Project Act was passed in 1928 In 1931 dam construction was begun in Black Canyon and Hoover Dam called Boulder Dam from 19331946 was completed in 1936 two years ahead of schedule The resulting Lake Mead named in honor of U S Reclamation Commissioner Dr Elwood Mead extends over 100 miles upstream can hold 2 years of flow from the Colorado River and has become a very popular recreation area for water sports

Abstract: Dr Sullivan explains that dermatology is the science of skin and its diseases Skin covering approximately 18 square feet is a humans largest organ and serves as the bodys protection Using both live animals from the Baltimore Zoo and representations of animals Dr Sullivan explains their protective mechanisms the lizards skin changes color for camouflage the ducks preen gland maintains its feathers with a precursor of vitamin D the rats sebaceous glands repel lice the lions mane protects it from other animals bites and a turtles shell a porcupines quills and a pachyderms thick skin all protect the animal within Dr Sullivan draws a diagram of the layers of human skin stressing the epidermis and protective barrier that prevents water from penetrating skin He notes that a frog has no transitional layer so its skin can take up water The human sweat glands continuously secrete a wet film on the skin The sebaceous glands secrete sebum which contains two emulsifiers that allow the skin to sweat
