GREAT HOMEOPATHS

On the anniversary of his death, here's a little on the life and times of one of our early homeopaths - Dr. Clemens Von Boenninghausen
M.D.
(1785-26/01/1864)

Dr. Boenninghausen was born to one of the oldest noble families of Westphalia, Germany. His full name was Clemens Maria Franz Baron Von Boenninghausen. He was Baron by inheritance, a lawyer by profession, and an agriculturist by natural inclination. He held respected and responsible posts in Germany and enjoyed a life of position and influence.
As a Doctor of Law, Dr. Boenninghausen practiced as a lawyer for some time and later became a judge. Because of his interest in horticulture, he was made Director of Botanical Gardens at Munster. Here, he came to be known as the "Sage of Munster." It was in 1827 that he developed purulent tuberculosis.

When he did not find any relief from the best orthodox treatment, and the physicians gave no hope of his recovery, he wrote a letter to his friend, Dr. A. Weihe, expressing his hopelessness for life and bidding him his last goodbye. Dr. A. Weihe was a homoeopath and asked Boenninghausen to try homoeopathic treatment. Fortunately for Boenninghausen and for homoeopathy, Dr. Weihe cured him.
Being greatly impressed with his treatment Boenninghausen took deep interest in studying homoeopathy and devoted his remaining years to the cause of homoeopathy. During this time he maintained regular correspondence with Dr. Hahnemann. Most of his systematic works concerning homoeopathy were published between 1828 and 1846. He was a regular contributor of articles on homoeopathic subjects to the journals.

GREAT MATHEMATCIANS

Galileo Galilei was born on 15 February 1564 in Pisa and was educated at the Camaldolese Monastery at Vallombrosa. In 1581 was sent by his father to enrol for a medical degree at the University of Pisa. Galileo never seems to have taken medical studies seriously, attending courses on his real interests which were in mathematics and natural philosophy. He left Pisa in 1585 without completing his medical degree and began teaching mathematics in Florence and later at Siena. During the summer of 1586 he taught at Vallombrosa, and in this year he wrote his first scientific book The little balance (La Balancitta) which described Archimedes' method of finding the specific gravities of substances using a balance. His reputation grew and in 1588 he received a prestigious invitation to lecture on the dimensions and location of hell in Dante's Inferno at the Academy in Florence. In 1589, Galileo was appointed to the Chair of Mathematics at the University of Pisa where he wrote De Motu a series of essays on the theory of motion which he never formally published. The book contains his important idea that one can test theories by conducting experiments and gave the famous example of testing falling bodies using an inclined plane to slow down the rate of descent.
In 1591,Vincenzo Galilei, Galileo's father, died and as the eldest son Galileo had to provide financial support for the rest of the family. Being Professor of Mathematics at Pisa was not well paid, so Galileo lobbied for a more lucrative post. In 1592, Galileo was appointed Professor of Mathematics at the University of Padua (the University of the Republic of Venice) at a salary of three times that he had received at Pisa. On 7 December 1592 he gave his inaugural lecture and began a period of 18 years at the University, years which he later described as the happiest of his life. At Padua his duties were mainly to teach Euclid's geometry and standard (geocentric) astronomy to medical students, who would need to know some astronomy in order to make use of astrology in their medical practice. While in Padua, Galileo publicly argued against Aristotle's view of astronomy and natural philosophy.

At Padua, Galileo began a long‐term relationship with Maria Gamba; however they never married. In 1600 their first child Virginia was born, followed by a second daughter, Livia, in the following year. In 1606 their son Vincenzo was born. Much later when his daughters were being educated at the Franciscan Convent of St Matthew outside Florence, Virginia took the name Sister Maria Celeste and Livia the name Sister Arcangela. Since they had been born outside of marriage, Galileo believed that they themselves should never marry.

In May 1609, Galileo received a report telling him about a spyglass that a Dutchman had shown in Venice. Using his own technical skills as a mathematician and as a craftsman, Galileo began to make a series of telescopes whose optical performance was much better than that of the Dutch instrument. His first telescope was made from available lenses and gave a magnification of about four times. To improve on this Galileo learned how to grind and polish his own lenses, and by August 1609 he had an instrument with a magnification of around eight or nine. Galileo immediately saw the commercial and military applications of his telescope (which he called a perspicillum) for ships at sea.

By the end of 1609 Galileo had turned his telescope on the night sky and began to make remarkable discoveries which he described in a short book called the Starry Messenger, published in Venice in May 1610. Galileo claimed to have seen mountains on the Moon, to have proved the Milky Way was made up of tiny stars, seen (although not understood their nature) the rings of Saturn, four small bodies orbiting Jupiter, and most importantly noted that the planet Venus showed phases like those of the Moon, and therefore must orbit the Sun, not the Earth. Galileo knew that all his discoveries were evidence for Copernicanism, although not a proof. Other observations made by Galileo included the observation of sunspots. He reported these in Discourse on floating bodies which he published in 1612 and more fully in Letters on the sunspots, which appeared in 1613.

The Jovian moons, with an eye to getting a position in Florence, he quickly named 'the Medicean stars'. He had also sent Cosimo de Medici, the Grand Duke of Tuscany, an excellent telescope for himself. In June 1610, only a month after his famous little book was published, Galileo resigned his post at Padua and became Chief Mathematician at the University of Pisa (without any teaching duties) and Mathematician and Philosopher to the Grand Duke of Tuscany.
In 1611, he visited Rome where he was treated as a leading celebrity. He was also made a member of the Accademia dei Lincei and this was an honour which was especially important to Galileo who signed himself 'Galileo Galilei Linceo' from this time on.

Despite his private support for Copernicanism, Galileo tried to avoid controversy by not making public statements on the issue. At a meeting in the Medici Palace in Florence in December 1613 with the Grand Duke Cosimo II and his mother the Grand Duchess Christina of Lorraine, Castelli, the successor to Galileo in the Chair of Mathematics at Pisa, was asked to explain the apparent contradictions between the Copernican theory and Holy Scripture. Castelli defended the Copernican position vigorously and wrote to Galileo afterwards telling him how successful he had been in putting the arguments. Galileo, less convinced that Castelli had won the argument, wrote Letter to Castelli to him arguing that the Bible had to be interpreted in the light of what science had shown to be true. Galileo's enemies ensured that a copy of the Letter to Castelli was sent to the Inquisition in Rome. However, after examining its contents they found little to which they could object. The point at issue for the Inquisition was whether Copernicus had simply put forward a mathematical theory which enabled the calculation of the positions of the heavenly bodies to be made more simply or whether he was proposing a physical reality.

In 1616 Galileo wrote a letter to the Grand Duchess Christina of Lorraine which vigorously attacked the followers of Aristotle. In this work, he argued strongly for a non‐literal interpretation of Holy Scripture when the literal interpretation would contradict facts about the physical world proved by mathematical science. In this Galileo stated quite clearly that for him the Copernican theory is not just a mathematical calculating tool, but is a physical reality: “…I hold that the Sun is located at the centre of the revolutions of the heavenly orbs and does not change place, and that the Earth rotates on itself and moves around it. Moreover ... I confirm this view not only by refuting Ptolemy's and Aristotle's arguments, but also by producing many for the other side, especially some pertaining to physical effects whose causes perhaps cannot be determined in any other way, and other astronomical discoveries; these discoveries clearly confute the Ptolemaic system, and they agree admirably with this other position and confirm it” . Pope Paul V then ordered that Sacred Congregation of the Index decide on the Copernican theory. The cardinals of the Inquisition met on 24 February 1616 and took evidence from theological experts. They condemned the teachings of Copernicus and the decision was conveyed to Galileo, who had not been personally involved in the trial. Galileo was forbidden to hold Copernican views.
Maffeo Barberini, who was an admirer of Galileo, was elected as Pope Urban VIII and invited Galileo to papal audiences on six occasions and led Galileo to believe that the Catholic Church would not make an issue of the Copernican theory. Galileo, therefore, decided to publish his views believing that he could do so without serious consequences from the Church. By this stage in his life Galileo's health was poor and it took him 6 years to complete his famous Dialogio. Galileo attempted to obtain permission from Rome to publish the Dialogue in 1630, but this did not prove easy. Eventually he received permission from Florence, not Rome. In February 1632 Galileo published Dialogue concerning the two chief systems of the world: Ptolemaic and Copernican and shortly after its publication the Inquisition banned its sale and ordered Galileo to appear in Rome before them. Galileo's accusation at the trial which followed was that he had breached the conditions laid down by the Inquisition in 1616. However, a different version of this decision was produced at the trial rather than the one Galileo had been given at the time. When found guilty and after making his abjuration of heliocentricity, he famously uttered the apocryphal words to himself “Epur si muove“ (And yet it does move).

Galileo was condemned to lifelong imprisonment, but the sentence was carried out somewhat sympathetically and it amounted to house arrest rather than a prison sentence. In 1634, he suffered a severe blow when his daughter Virginia, Sister Maria Celeste, died. She had been a great support to her father through his illnesses and Galileo was shattered and could not work for many months. When he did manage to restart work, he began to write Discourses and mathematical demonstrations concerning the two new sciences. After Galileo had completed work on the Discourses it was smuggled out of Italy, and taken to Leyden in Holland, where it was published. It was his most rigorous mathematical work which treated problems on impetus, moments, and centres of gravity. In the Discourses he developed some of his most famous and enduring mathematical ideas, such as on the motion of objects on an inclined plane, the acceleration of free‐falling bodies, as well as the movement of the pendulum.

Galileo died in Arcetri (near Florence) #OnThisDay 8 January 1642. It was a sad end for so great a man to die condemned of heresy. His will indicated that he wished to be buried beside his father in the family tomb in the Basilica of Santa Croce, but his relatives rightly feared that this would provoke opposition from the Church. His body was concealed and only placed in a fine tomb in the church in 1737 by the civil authorities against the wishes of many in the Church. On 31 October 1992, 350 years after Galileo's death, Pope John Paul II gave an address on behalf of the Catholic Church in which he admitted that errors had been made by the theological advisors in the case of Galileo. He declared the Galileo case closed, but he did not admit that the Church was wrong to convict Galileo on a charge of heresy because of his belief that the Earth rotates round the sun.

GREAT POETS

Biography of John Milton

John Milton was born in London in 1608 at the height of the Protestant Reformation in England. His father was a law writer who had achieved some success by the time Milton was born. This prosperity afforded Milton an excellent education, first with private tutoring, then a private school, and finally Cambridge. Milton, a studious boy, excelled in languages and classical studies.

His father had left Roman Catholicism and Milton was raised Protestant, with a heavy tendency toward Puritanism. As a student, he wanted to go into the ministry, but was disillusioned with the scholastic elements of the clergy at Cambridge. Cambridge, however, afforded him time to write poetry. 

After Cambridge, he continued his studies for seven years in a leisurely life at his father's house. It was here that he wrote some of his first published poems, including "Comus" (1634) and "Lycidas" (1638), both of which he published in 1645.

Milton toured the European continent in 1638-1639 and met many of the great Renaissance minds, including Galileo and Grotius. The beginning of the Puritan Revolution found Milton back in England, fighting for a more humanist and reformed church.

 For more than twenty years, Milton set aside poetry to write political and religious pamphlets for the cause of Puritanism. For a time, he served as Secretary for Foreign Tongues under Cromwell.

Milton was a mixed product of his time. On the one hand, as a humanist, he fought for religious tolerance and believed that there was something inherently valuable in man. As a Puritan, however, he believed that the Bible was the answer and the guide to all, even if it went against democracy itself. Where the Bible didn't afford an answer, Milton would turn to reason.

Milton himself was married three times, all of which were rather unhappy affairs. He defended divorce in "The Doctrine and Discipline of Divorce" in 1643. With this and other treatises, Milton often came in conflict with the Puritanism he advocated.

At the end of the war, Milton was imprisoned for a short time for his views. In 1660, he emerged blind and disillusioned with the England he saw around him.

Nevertheless, he was yet to write his greatest work. Paradise Lost was published in 1667, followed by Paradise Regained in 1671. Milton's ability to combine his poetry with his polemics in these and other works,was the key to his genius.

The classical influences in his work can be clearly delineated: Homer, Ovid, but especially Virgil. Shakespeare was the leading playwright of his day, and there are some references to his works in Milton's own poetry. 

The style and structure of the Spencer's "The Faerie Queen," was another influence on Paradise Lost. It was one of only a few books that were owned by the Miltons during John's upbringing.Milton died from "gout" in 1674 and was buried in the Church of St. Giles in London.

GREAT SCIENTISTS : MAX PLANCK

Birth of Quantum Theory
#OnThisDay 14th December in1900, German physicist Max Planck published his groundbreaking study of the effect of radiation on a “blackbody” substance, and the quantum theory of modern physics was born.

Through physical experiments, Planck demonstrated that energy, in certain situations, can exhibit characteristics of physical matter. According to theories of classical physics, energy is solely a continuous wave-like phenomenon, independent of the characteristics of physical matter. Planck’s theory held that radiant energy is made up of particle-like components, known as “quanta.” The theory helped to resolve previously unexplained natural phenomena such as the behavior of heat in solids and the nature of light absorption on an atomic level. In 1918, Planck was awarded the Nobel Prize in physics for his work on blackbody radiation.
Other scientists, such as Albert Einstein, Niels Bohr, Louis de Broglie, Erwin Schrodinger and Paul M. Dirac, advanced Planck’s theory and made possible the development of quantum mechanics—a mathematical application of the quantum theory that maintains that energy is both matter and a wave, depending on certain variables. Quantum mechanics thus takes a probabilistic view of nature, sharply contrasting with classical mechanics, in which all precise properties of objects are, in principle, calculable. Today, the combination of quantum mechanics with Einstein’s theory of relativity is the basis of modern physics.
