About 4000 B.C. they added five extra days at the end of every year to bring it more into line with the solar year. These five days became a festival because it was thought to be unlucky to work during that time. The Egyptians had calculated that the solar year was actually closer to 365 /4 days, but instead of having a single leap day every four years to account for the fractional day (the way we do now), they let the one-quarter day accumulate. After 1,460 solar years, or four periods of 365 years, 1,461 Egyptian years had passed. This means that as the years passed, the Egyptian months fell out of sync with the seasons, so that the summer months eventually fell during winter. Only once every 1,460 years did their calendar year coincide precisely with the solar year.

Later in the same year he inherited a moiety in the estates of his uncle and guardian the Earl of Essex. He immediately took up the Royalist cause and moved to Oxford; after the execution of Charles I he was several times imprisoned in the Tower for his involvements in plots to restore the monarchy and died there perhaps as a result of poisoning.

The whole world reestablished this book starting with the Islamic translation on through time. THALES, FOUNDER OF GREEK GEOMETRY (585 B.C.E.) The birth of Greek astronomy has been attributed to Thales of Miletus. Thales brought from Egypt a number of fundamental geometric principles. Thales, an Ionian (western border of Asia Minor) who was active near the start of the sixth century bc has been credited with a number of geometric theorems. 1. A Circle is bisected by its diameter. 2. Angles at the base of any isosceles triangle are equal. 3. If two straight lines intersect the opposite angles formed are equal. 4. If two triangles have two angles and one side respectively equal, the triangles are equal in all respects. Thales was also well known for forecasting the solar eclipse, so he was also considered a scientist.

Father Henry GARNET Born: 1555, Heanor, East Derbyshire, England Died: 3 May 1606, Saint Paul's Churchyard, London, England Father: Brian GARNET Mother: Alice JAY Born in the second half of the year 1555, probably at Heanor, a small market town in east Derbyshire. His early childhood was spent, however, in Nottingham, where his father, Brian Garnet had become the head master of the Free Grammar School in 1565. Brian Garnet descended from a family that traces its origins back to Ralph De Gernet , a learned gentleman who came to England from Norman France in the time of William the Conqueror . The Gernets had settled mostly in the north-western part of England, became landholders in Westmorland and Lancashire and gained the right to bear arms. One branch of this early Gernet family had distinguished itself as sergeants of the King's Forest throughout Lancaster and by the thirteenth century held vast estates at Halton, Heysham, Lydiate and Coton. Although holding land and positions of power during the Middle Ages, the later Gernets made their mark more in learning than in politics. Throughout the sixteenth century, the family's surname, by then written most commonly as Garnet, occurs frequently in the registers of the colleges at Oxford. When a grammar school in Westmorland was granted a charter in 1591, two Garnets were recorded among its Governors. Brian Garnet Henry 's father, remained for the rest of his life a devoted classical scholar and outwardly a religious conformist. But secretly he was a Catholic by conviction. Apart from young

Early in the movie, a lunar expedition uncovers a large, black monolith in the crater Clavius. Although the movie was fictional, and computers have not yet reached HAL's ability to speak and read lips, the lunar crater Clavius does exist and is named after a sixteenth century scholar who was instrumental in introducing mathematics into the university curriculum. Christopher Clavius (1538-1612) is often associated with the astronomical and mathematical justification for shifting from the Julian to the Gregorian calendar. He was also a university professor who was convinced that mathematics should be a standard part of a university curriculum and who saw the need to train instructors of mathematics. He exerted his influence on the Ratio Studiorum (The Plan of Studies), a 1599 document that included administrative norms and curricular guidelines for Jesuit schools as well as offering pedagogical suggestions in the form of "Rules" for teachers of various subjects (the Latin text [15] and English translations [6, 7] are available).

At Los Alamos, known for its secret origins in the Manhattan Project, but where researchers today map chromosomes as well as the national power grid, Fr. Opeil will do spectroscopic readings and electron-structure measurements on uranium to shed light on basic properties of the element. "My work is pure science," said Fr. Opeil, one of a handful of American Jesuit physicists, several of whom are at the Vatican Observatory. "The aim is a better understanding of the nature of surface electrons in single crystal uranium and its oxides."

One major area of bioinformatics/computational biology involves the design, implementation, and application of algorithms to answer fundamentally important questions in biology, such as the following: What is the energy landscape in the folding process of the molecular RNA? (RNA is involved in both transcription and translation, as well as post-transcriptional modification, such as expression-level silencing or knock-down of certain genes via small interfering RNA. Understanding the optimal and suboptimal secondary structures of RNA plays an important role in all these processes.)

Gregorian Reform Despite territorial, political and linguistic differences, Europe uses the same calendar. Wherever you are in the continent, the rest is either just entering, just leaving, or in the middle of, the same date. This dating system, used by Europe and the rest of the 'westernized' world, was introduced in 1582; it is the Gregorian Calendar. However, this uniformity is a modern luxury, and for most of the early modern and modern period Europe operated under several calendars which were weeks, and in the case of Ottoman territories years, apart. This is an account of the introduction, and adoption, of the Gregorian Calendar. Until 1582 Europe operated in the Julian Calendar, a system of dating which used a year of 365 days, with a 366th every four years. Unfortunately, the Julian calendar had a minor error: the average Julian year was 365 days and 6 hours (the extra quarter being added in the leap years), while the actual solar year is 365 days, 5 hours, 48 minutes and 46 seconds, a difference of just over eleven minutes. (Please note: there is some debate among astronomers and other parties as to what actually constitutes the solar year, and these figures can vary by several seconds.) As a result, for every Julian year that passed the human calendar became increasingly out of synch with the natural solar cycle.

59. Jesuit Contribution To Seismology A key figure in this development was christopher clavius (15371612), Professorof Mathematics in the Collegio Romano. clavius was instrumental in http://www.seismosoc.org/about/ES_Jesuits.html

S EISMOLOGICAL S OCIETY OF A MERICA ABOUT: JESUITS AND SEISMOLOGY The Jesuit Contribution to Seismology by and William Stauder, Saint Louis University (from Seismological Research Letters Vol. 67, No. 3, pp. 10-19; May/June 1996) INTRODUCTION A series of circumstances and interests involved Jesuits in the development of this new science from its inception. This interest, certainly, was consonant with the tradition of Jesuits in science dating from the 16th century, which developed, as has been mentioned, out of their work in colleges and universities. The character of seismology as a public service to mitigate the destructive effects of earthquakes was another influential factor. Especially in undeveloped countries, Jesuits were in many instances the first to install seismographic stations and to carry out seismicity and seismic risk studies. Two trends may be distinguished in this involvement of Jesuits in seismology. In the United States, emphasis was on the cooperation of Jesuit institutions in the establishment of seismographic stations organized first as the Jesuit Seismological Service and subsequently as the Jesuit Seismological Association. In other countries, especially in mission lands, the movement developed out of the activity of individual institutions in establishing seismic observatories, usually as a complement to the recording of other geophysical data. JESUIT SEISMOGRAPHIC STATIONS Other Jesuit seismographic stations in Cuba and Chile functioned only a few years. In 1940 a seismographic station was installed in St. George's College, Kingston, Jamaica, dependent on Weston Observatory. In Montreal, Canada, a seismographic station was installed in 1952 (Buist, 1983). The Montreal station was a modern station with WWSSN-type instruments. It was the last new station installed under direct Jesuit auspices. Maurice Buist was its director for thirty-one years until his retirement in 1983. In Ethiopia Haile Salassie invited the Jesuits to undertake the administration of the National University in Addis Ababa. Although not a Jesuit station in the strict sense, the associated Geophysical Observatory of Addis Ababa was directed by the Canadian Jesuit Pierre Gouin from 1957 to 1978. In 1962, a WWSSN seismographic station was installed.
