Charles Carter was one of the great English astrologers of the twentieth century. With Alan Leo, John Addey and Charles Harvey, Carter transformed astrology in England. He introduced technical and philosophical innovations and participated in a number of key institutional developments. Charles Carter was born on 31 January 1887 at 10:55PM in Parkstone, Dorset. He had an Aquarian Sun in the 4th house, and Uranus rising in Leo just into the 12th. At his birth, Saturn had just culminated in Cancer. With this combination of rising Uranus and an elevated Saturn, Carter was well-figured to lead the astrological world. He died in October 1968. 1 His astrological service included a number of key appointments. In 1922 Carter followed Leo as the President of the Astrological Lodge of London and revived the institution. In 1948 he became the first Principal of the Faculty of Astrological Studies. In 1958 he became a founding Patron of the Astrological Association of Great Britain. Carter's legacy is remembered at the annual Astrological Association conference. A leading astrologer is invited to deliver the Carter Memorial Lecture as the central plenary session of the event. This invitation is one of the highest accolades an astrologer can receive. Carter wrote a number of significant books including The Principles of Astrology (1925), Zodiac and the Soul (1928) and Essays on the Foundations of Astrology (1947). He reflected on key philosophical issues in The Seven Great Problems of Astrology (1927). He advocated the use of some innovative directional methods in his slim volume Symbolic Directions in Modern Astrology (1929). Charles Carter introduced a technical innovation that is almost forgotten today - his poli equatorial house system. He described his system of domification in Essays on the Foundations of Astrology. The method is found in Chapter 8, Problems of the Houses. In the chapter, Carter reviews many of the principle systems of domification including the Regiomontean, the Campanean, the Equal and the Placidean. He then introduces his own method so nonchalantly that the reader may miss the significance of the text. Carter writes that in his poli equatorial method “...the houses are demarcated by circles passing through the celestial poles and dividing the equator into twelve equal arcs, the cusp of the 1st house passing through the ascendant. This system, therefore, agrees with the natural rotation of the heavens and also produces, as the Ptolemaic (equal) does not, distinctive cusps for each house....” 2 Calculation of the cusps is a relatively simple affair. The ascendant degree is converted to right ascension in degrees. Thirty degrees (or two hours) of right ascension is then added for each subsequent cusp. The right ascension so found is, for each cusp, then converted back to celestial longitude and expressed in zodiacal degrees. The tenth house cusp will not generally coincide with the MC degree. The second cusp is opposite the eighth cusp, the third opposite the ninth and so on. Figure 1: Charles Carter's Poli Equatorial House System - Diagram Carter notes that the Regiomontanean system of domification also uses equal division of the equator as its foundation. In fact, Carter's poli equatorial system is one of a family of house systems derived from equal division of the celestial equator. The others are the Morinean and the Meridian (or Axial Rotation) house systems. The following table sets out the basic elements of the four equatorially-based systems of domification. System Pole Notes Poli equatorial Equatorial (Celestial) The 1st house cusp will coincide with ascendant but the 10th house cusp will not generally coincide with the meridian Regiomontanus Horizontal The 10th and 1st house cusps coincide with the meridian and the ascendant respectively Morinus Ecliptic Neither the 10th house cusp nor the 1st house cusp will coincide with the meridian or the ascendant Meridian (or Axial Rotation) Equatorial (Celestial) The 10th house cusp will coincide with the meridian, but the first house cusp is the equatorial ascendant Table 1: Comparison of Equatorially-Based House Systems Holden describes Regiomontanus, Morinus and Meridian as house systems as space-based methods of domification. Although the Earth's rotation determines the length of our day (a time factor), Holden's view is that the equal division of the equator in each system is primarily a division of the celestial sphere as a spatial unit. 3 Figure 2: The Equatorial Frame of Reference In Carter's poli equatorial house system, we find a method of domification that draws on ideas from Platonic cosmogony and cosmology, being derived from equal divisions of the circle of the Same (celestial equator) projected onto the circle of the Different (ecliptic). The ascendant is used as the cusp of the first house. In developing a method of house division that uses the circles of the Same and Different, Carter gives us a system of domification that is integrated with Platonic philosophy. This philosophy is so often the unspoken foundation of much astrological lore. A good example of the poli equatorial house system in action is the Exeter Astrology Group's own natal chart. (See below) In this chart the important Venus-Uranus opposition is moved to within a few minutes of arc of the 4th-10th axis. This symbol describes the purpose of the group of the group very clearly - a public gathering of friends (Venus-10th cusp) built around the foundations of a shared interest in astrology (Uranus-4th cusp). The solar identity of the group is in the collectively focused 11th house, and Mercury, being the classical symbol for astrology is close to the cusp of the 12th, the spiritual house. Jupiter, often in the 2nd house using mainstream systems, moves to the cusp of the 3rd house, a symbol for a group dedicated to learning and sharing information of a spiritual and philosophical nature. The poli equatorial system is clearly effective in this delineation. Figure 3: Exeter Astrology Group (using Poli Equatorial Houses) The cusps are listed below: Cusp 1: 6 SC 19 Cusp 2: 5 SG 53 Cusp 3: 3 CP 40 Cusp 4: 1 AQ 44 Cusp 5: 2 PI 0 Cusp 6: 4 AR 21 Cusp 7: 6 TA 19 Cusp 8: 5 GE 53 Cusp 9: 3 CN 40 Cusp 10: 1 LE 44 Cusp 11: 2 VI 0 Cusp 12: 4 LI 21 (Note to programmers - if you would like a simple BASIC program to calculate poli equatorial house cusps, please contact the author via the EAG website. This program is provided on an open source basis to promote the inclusion of poli equatorial houses in commercial and non-commercial astrological software. You may adapt it to your own needs/programming language.) It is disappointing that Carter's method of domification is so little used. It is not mentioned in key texts that describe the principles of house systems. It is not offered in any of the main programmes available in the astrological software market. Furthermore, there is very little information about the system available on the internet. I have never seen a published chart delineated according to the poli equatorial system apart from Carter's own examples. 4 In Carter's day, his method had one undeniable advantage – it needed a single table of houses. This meant that calculation of houses cusps was simplified. Once the ascendant had been calculated, the other cusps could be read directly from a page of data. This is because poli-equatorial cusps are not latitude-dependent (once the ascendant has been identified). Carter's system has other benefits. It creates houses that are more or less equal, in terms of the twelve divisions of the ecliptic that they demarcate. This minimises the issue of intercepted signs. The system will occasionally fall down in charts where the calculation of the ascendant is problematic. This only occurs in extreme polar latitudes. However, Rob Hand notes that this difficulty is more theoretical than practical. The identification of an ascendant in these latitudes is only impossible when the horizon and ecliptic coincide. According to Hand “...this occurs for only an instant and only on the infinitesimal band of the Arctic and Antarctic circles, so it is not a serious drawback in practice.” 5 Carter's system has a clear advantage over quadrant based methods of domification in polar latitudes because it does not rely on the need for an identified midheaven and ascendant. This issue can be a difficulty because the ascendant and meridian can coincide at times. More commonly, the midheaven and ascendant can fall close together on the ecliptic in high northern latitudes. This leads to gross discrepancies in the size of quadrant houses when measured on the ecliptic. In Essays on the Foundations of Astrology, Carter provides a number of interesting case examples to illustrate his poli equatorial system. He looks at charts for Tennyson, the great Victorian poet, King Edward VII, and Emily Popejoy. In the King's chart, Carter points out that with the poli equatorial system, “The presence of the Moon, in close square to Saturn, on cusp 10 seems peculiarly appropriate to the native's strict upbringing and suppression by his royal Mother, who refused for many years to allow him to take part in public affairs. Venus in the 10th agrees with his popularity and that of his consort.” 6 In other systems, the moon would fall variously in the eighth or ninth houses; in most systems Venus would fall solidly in the cadent ninth. Carter notes Tennyson's tight Mars-Uranus conjunction falls in the sixth house in many house systems. He concludes that this symbolism “...seems inappropriate to the native's robust health....” 7 Carter suggests this pair “...would be much better placed in the 5th, indicating the emotional tragedy which led to In Memoriam and the death of the poet's son of fever.” 8 Using the poli equatorial method, Uranus and Mars fall in the fifth house, suggesting the unexpected death of a child. He also notes that in the poli equatorial system, Jupiter moves from the cusp of the twelfth house onto the cusp of the eleventh house which “...seems to agree much better with the poet's phenomenal success....He won fame, rank and money.” 9 Carter's method of domification also has some practical benefits, including house cusps that fall more or less equally on the ecliptic and have unique degrees. The astrologer has to accept that the midheaven is unlikely to form the cusp of the tenth, but, as Carter has demonstrated, this may, in practice, yield important interpretative insights. We should do Carter the honour of looking at his own nativity using the poli equatorial method he devised. In many systems, including all quadrant based methods of house division, his highly elevated Saturn falls in the cadent ninth house, being just beyond the culminating degree in the diurnal circle. Despite Saturn's lack of traditional dignity, this placement is an adequate symbol for his fine philosophical mind. His astrological vision moved subtly between the realms of the Platonic world of Ideas and the mundane world which we inhabit. However, this image does not carry the authority of a man who served the astrological community at the highest levels for many years. In the equal house system, we note that his Saturn is on the nonagesimal degree. This degree, falling exactly square to the ascendant, marks the 10th house cusp in the simple equal house method of domification. 10 The nonagesimal degree is the highest point of the ecliptic above the horizon; any planet placed in this degree is given prominence within the horoscope. However, when we use his own poli equatorial method of domification, Carter's Saturn falls a few degrees inside the tenth, the cusp being at 14 Cancer. This is testament to Carter's own observation that his poli equatorial method, having many of the advantages of the straightforward modus equalis or Ptolemaic system, has the further benefit of yielding cusps that carry a unique mundane signature. Figure 3: Charles Carter's Horoscope (using Poli Equatorial Houses) This symbol – Saturn in the tenth house - clearly identifies Charles Carter's authority and acumen. He worked to establish and maintain the institutions that still embody the mainstream traditions in English and British astrology. He took a large share of responsibility for the good governance of some of the key political and educational institutions that represent our cosmic art. There can be no higher recommendation for Carter's poli equatorial house system than this signature from his own nativity. Notes and References 1.

Computers, and technology in general, have come a long way in today’s world. The modern world is actually shaped and defined through the usage of computers, those neat little gadgets that do the hard work for you. Modern computers are also perfectly capable of entertaining, organizing, reminding, even surprising you. That wasn’t always the case. Here is glimpse of the history of computers and their humble beginnings. These computers may not have been as powerful as modern computers, but they’re old black and white photos are intriguing nevertheless. If for no other reason, then because those old computers were capable of filling a whole room with their robust circuitry. Enjoy these old photos of the first generation of computers. AVIDAC, Argonne’s first digital computer, began operation in January 1953. It was built by the Physics Division for $250,000. Pictured is pioneer Argonne computer scientist Jean F. Hall. The CSIRAC was Australia’s first computer. The name stands for CSIR originally stood for “Council for Scientific and Industrial Research”. This name was in effect from 1926 to 1949. The computer history at NTNU is much older than the computer departments. The very first computer at NTNU was called DIANA, or DIfferential ANAlysator. This was an analog electronic computer built by Jens Glad Balchen and the Division of Cybernetics in the years between 1952 and 1955. A press conference for what is considered the first computer, the Electronic Numerical Integrator and Calculator (ENIAC), was held at the University of Pennsylvania on February 1, 1946. The machine (shown here with a technician) took up an entire room, weighed 30 tons and used more than 18,000 vacuum tubes to perform functions such as counting to 5,000 in one second. ENIAC, costing $450,000, was designed by the U.S. Army during World War II to make artillery calculations. The development of ENIAC paved the way for modern computer technology–but even today’s average calculator possesses more computing power than ENIAC did. First ever apple computer running windows. This is an Apple II with a monochrome screen and PC emulator hardware installed. The board was called the 88 Card, “the only fully functional 8088 processor for the Apple II personcal computer.

The rotating drum technology allowed ERA to deliver the world’s first production stored-program computer (ATLAS – ERA 1101) to a customer site in October 1950. The engineers making the installation delivery to the National Security Agency predecessor were Frank Mullaney and Jack Hill. As shown in the photo below, these drum products came in various sizes. They were first used in several classified processors, then in the early 1100 computer series and the UNIVAC SS-80 and SS-90 computers. Dr. Cohen and Sid Rubens are credited with patenting the rotating magnetic drum. The drum development engineers and management shown in this early 50’s photo, left to right are: William Keye, Arnold Hendrickson, Robert Perking, Frank Mullaney, Dr. Arnold Cohen, and John ‘Jack’ Hill. The first ever computer in Latvia was developed and made at the start-up Institute of Electronics and Computer Science in early sixties. No computers were made industrially in USSR at that time. Therefore successful completion of that project certainly represented a significant achievement. Built on a lot of vacuum tubes, the computer actually worked well and was used for supporting research activities for several years till the time when it became possible to replace it by a more powerful industrially made computer. IBM 701. IBM’s first computer. Introduced in 1952, the 701 was designed for scientific work and research, which later led to the development of the high-level FORTRAN language. Nineteen machines were built, a record volume for such a machine in that era. Its internal memory contained 2,048 36-bit words of electrostatic memory and 8,192 words of magnetic drum memory (see early memories). It used magnetic tapes for storage and was one of the first machines to use plastic-based tapes instead of metal tapes. See IBM 650 and IBM 1401. At General Electric’s Aircraft Jet Engine Plant in Evendale, Ohio, this 1954 photo shows GE manager Herbert Grosch explaining the 701 to Ronald Reagan. Reagan was a TV personality for GE at the time. Amdahl Corporation, Sunnyvale, CA. A computer manufacturer founded in 1970 by Dr. Gene Amdahl, chief architect of the IBM System/360. In 1975, Amdahl installed its first IBM-compatible mainframe, the 470/V6. In 1979, Amdahl left the company he founded to form Trilogy, which tried without success to make the world’s largest chip based on wafer scale integration.
