Support of science and technology is a major component of the Foundation's program. Fellowships, direct support of research in selected fields, and work in the history of science and technology are basic parts of this program.

Human populations through time have often flourished near the sea, partly because of the food resources that can be found there, but also because of the ease of transportation of people and cargo by boats. Observations about various organisms and environments were of course a major part of human activities since the earliest times, since the very survival of early Homo sapiens depended on this knowledge to obtain food and provide defense against dangerous plants and animals.

Human Nature Review is a significant source of analysis and commentary for readers at leading universities and research institutes in over one hundred and sixty countries and is one of the most popular sites on the whole world wide web.Our goal is to bring into communication the variety of approaches to understanding human nature which have a regrettable tendency to be less in touch with one another than they might. We aim to act as host to original work and to seek to create an enabling space, a forum for constructive (including constructively critical) discussion and critiques of the terms of reference and assumptions of various approaches to the understanding of people as individuals, in groups, in institutions, in societies and as political and ideological beings.

Hindu cosmological time cycles, as well as common units of measuring time and angles, are generated from the concept that the Sun has three distinct mean motions which work together like the hour, minute and second hands of a clock. The exact sidereal solar year of 365.2563795 mean solar days, constant of precession of 50".4 and week of precessional years of 180,000 sidereal solar years used in the construction of the cycles may be inferred from their infrastructure. With the astronomical quantities known, the kaliyuga epoch of February 18, 3102 B.C. of the Julian calendar establishes the summer solstice as the initial tropical point of the cycles, 147108 B.C. as the beginning of the current week of precessional years and closely approximates the fixed initial point of the sidereal sphere given in the SuryaSiddhanta commentary.

Euclid (Alexandria) In his Optica he noted that light travels in straight lines and described the law of reflection. He believed that vision involves rays going from the eyes to the object seen and he studied the relationship between the apparent sizes of objects and the angles that they subtend at the eye

Welcome to the most comprehensive website for the history of phrenology—the most popular Victorian science. This site provides an accurate overview of phrenology, the largest collection of phrenological images, and many digitized primary sources relevant not only to the history of phrenology, but also to the history of naturalism and evolutionary thought.

Welcome to the Telephone Tribute Website! You'll find all sorts of telephone related web pages here on the history of the telephone, technical information, research resources, human interest stories, clubs, pictures, sound files, links, discussion forum, etc. If this is your first time here, you might try starting out your navigation of my web site by first looking at my Table of Contents or using the search engine to your right.

The Mercurians began meeting in 1986 for the purpose of generating networks between people who share work and interests in the history of communication technologies, defining the field broadly. Our activities include publishing a semi-annual newsletter, Antenna, meeting annually at Society for the History of Technology (SHOT) conferences, organizing paper sessions for SHOT meetings, and pursuing contacts between meetings. Antenna serves both as a clearing house for readers and an informal forum for their ideas. We welcome contributions, including notices and queries about Mercurians' projects as well as short essays on their work. Antenna includes book reviews and other materials about conferences, museums, publications, archives, funding, and other pertinent materials.

The story of physics in the 20th century unfolds like a splendid tapestry teeming with people, ideas, and things. In order to find patterns in this tangle, it helps to pick out five color-coded story-lines that stretch like broad, horizontal ribbons from beginning to end. The Cosmic, Human, and Atomic scales correspond to separate branches of physics. Up until 1900, classical physics dealt mostly with phenomena on the human scale, but for a description of the cosmic and atomic realms, new mathematical languages had to be developed. The three story-lines remained fairly distinct until the 1960s, when they finally began to converge in a synthesis that represents one of the great triumphs of modern physics.
