Mole Day

Mole Day is an unofficial holiday celebrated among chemists, chemistry students and chemistry enthusiasts on October 23, between 6:02 a.m. and 6:02 p.m. making the date 6:02 10/23 in the American style of writing dates. The time and date are derived from the Avogadro number, 6.02×1023, defining the number of particles in one mole of substance, one of the seven base SI units. Mole Day originated in an article in The Science Teacher in the early 1980s. Inspired by this article, Maurice Oehler, now a retired high school chemistry teacher from Prairie du Chien, founded the National Mole Day Foundation on May 15, 1991. Many high schools around the United States, South Africa and Canada celebrate Mole Day as a way to get their students interested in chemistry, with various activities related to chemistry or moles; the American Chemical Society sponsors National Chemistry Week, which occurs from the Sunday through Saturday during which October 23 falls. This makes Mole Day an integral part of National Chemistry Week.

Secretariat of Security and Civilian Protection (Mexico)

The Secretariat of Security and Civilian Protection is a cabinet-level agency of the government of Mexico responsible for supervising public safety and security, including the Federal Police, a new National Intelligence Center, the penitentiary system. Its secretary is Alfonso Durazo; the SSPC was created in 2018 by way of the omnibus reform package to the Organic Law of the Federal Public Administration for the presidency of Andrés Manuel López Obrador. It absorbed all of the security apparatus housed in the Secretariat of the Interior, including the National Security Commission; these functions had been in SEGOB since the Secretariat of Public Security was dissolved at the start of 2013. Among the tasks to be undertaken by the new SSPC are the formation of a new National Guard, which will absorb the 35,000 members of the military police and another 8,000 from the naval police

Heinrich Khunrath

Heinrich Khunrath, or Dr. Henricus Khunrath as he was called, was a German physician, hermetic philosopher, alchemist. Frances Yates considered him to be a link between the philosophy of John Rosicrucianism. Khunrath was born in Dresden, the son of the merchant Sebastian Kunrat and his wife Anna in the year 1560, he was the younger brother of the Leipzig physician Conrad Khunrath. In the winter of 1570, he may have enrolled at the University of Leipzig under the name of Henricus Conrad Lips; the uncertainties surrounding his life stem from his supposed use of multiple names. It is certain that in May 1588, he matriculated at the University of Basel, earning his Medicinæ Doctor degree on 3 September 1588, after a defense of twenty-eight doctoral theses. Khunrath, a disciple of Paracelsus, practiced medicine in Dresden and Hamburg and may have held a professorial position in Leipzig, he travelled after 1588, including a stay at the Imperial court in Prague, home to the mystically inclined Habsburg emperor Rudolf II.

Before reaching Prague he had met John Dee at Bremen on 27 May 1589, when Dee was on his way back to England from Bohemia. Khunrath praised Dee in his works. During his court stay Khunrath met the alchemist Edward Kelley who had remained behind after he and Dee had parted company. In September 1591, Khunrath was appointed court physician to Count Rosemberk in Trebona, he met Johann Thölde while at Trebona, one of the suggested authors of the "Basilius Valentinus" treatises on alchemy. Khunrath's brushes with John Dee and Thölde and Paracelsian beliefs led him to develop a Christianized natural magic, seeking to find the secret prima materia that would lead man into eternal wisdom; the Christianized view that Khunrath took was framed around his commitment to Lutheran theology. He held that experience and observation were essential to practical alchemical research, as would a natural philosopher, his most famous work on alchemy is the Amphitheatrum Sapientiae Aeternae, a work on the mystical aspects of that art, which contains the oft-seen engraving entitled "The First Stage of the Great Work", better-known as the "Alchemist's Laboratory".

The book was first published at Hamburg in 1595, with four circular elaborate, hand-colored, engraved plates heightened with gold and silver which Khunrath designed and were engraved by Paullus van der Doort. The book was made more available in an expanded edition with the addition of other plates published posthumously in Hanau in 1609. Amphitheatrum Sapientiae Aeternae is an alchemical classic, combining both magic. In it, Khunrath showed himself to be an adept of spiritual alchemy and illustrated the many-staged and intricate path to spiritual perfection. Khunrath's work was important in Lutheran circles. John Warwick Montgomery has pointed out that Johann Arndt, the influential writer of Lutheran books of pietiesm and devotion, composed a commentary on Amphitheatrum; some of the ideas in his works are Kabbalistic in foreshadow Rosicrucianism. Khunrath may have encountered some opposition to his alchemical work because most of his publications on alchemy were published after his death, he died in either Dresden or Leipzig on 9 September 1605.

The tension between spirituality and experiment in Amphitheatrum Sapientiae Aeternae brought about its condemnation by the Sorbonne in 1625. De signatura rerum naturalium theses. Basel. 1588.
