ʻIT IS ALL SO STRANGELY INTERTWINEDʼ: A DISCUSSION BETWEEN HANS BENDER AND CARL GUSTAV JUNG ABOUT SYNCHRONICITY (1960)

Hans Bender, German parapsychologist and professor at the Freiburg University, met with C. G. Jung on December 8, 1960. The discussion was recorded, and the transcribed version is available here for the first time in English. A key aspect of our article is a description of the phenomenon of synchronicity based on Hans Bender’s concrete experiences during a drive through Switzerland to an Eranos Conference in Ascona and further on to the Côte d’Azur for a workshop of the Parapsychology Foundation in August 1960. At the same time, his mother suffered a stroke, which caused her death shortly afterward. Bender was returning to Freiburg at the time when she died. He was familiar with the stages of his return trip from earlier trips. He had intensely emotional experiences at certain places, which he, in retrospect, interpreted as synchronistic in connection with his mother’s death. KEYWORDS C.G.

Radiation environment for future human exploration on the surface of Mars: the current understanding based on MSL/RAD dose measurements

Potential deleterious health effects to astronauts induced by space radiation is one of the most important long-term risks for human space missions, especially future planetary missions to Mars which require a return-trip duration of about 3 years with current propulsion technology. In preparation for future human exploration, the Radiation Assessment Detector (RAD) was designed to detect and analyze the most biologically hazardous energetic particle radiation on the Martian surface as part of the Mars Science Laboratory (MSL) mission. RAD has measured the deep space radiation field within the spacecraft during the cruise to Mars and the cosmic ray induced energetic particle radiation on Mars since Curiosity’s landing in August 2012. These first-ever surface radiation data have been continuously providing a unique and direct assessment of the radiation environment on Mars. We analyze the temporal variation of the Galactic Cosmic Ray (GCR) radiation and the observed Solar Energetic Particle (SEP) events measured by RAD from the launch of MSL until December 2020, i.e., from the pre-maximum of solar cycle 24 throughout its solar minimum until the initial year of Cycle 25. Over the long term, the Mars’s surface GCR radiation increased by about 50% due to the declining solar activity and the weakening heliospheric magnetic field. At different time scales in a shorter term, RAD also detected dynamic variations in the radiation field on Mars. We present and quantify the temporal changes of the radiation field which are mainly caused by: (a) heliospheric influences which include both temporary impacts by solar transients and the long-term solar cycle evolution, (b) atmospheric changes which include the Martian daily thermal tide and seasonal CO$$_2$$ 2 cycle as well as the altitude change of the rover, (c) topographical changes along the rover path-way causing addition structural shielding and finally (d) solar particle events which occur sporadically and may significantly enhance the radiation within a short time period. Quantification of the variation allows the estimation of the accumulated radiation for a return trip to the surface of Mars under various conditions. The accumulated GCR dose equivalent, via a Hohmann transfer, is about $$0.65 \pm 0.24$$ 0.65 ± 0.24 sievert and $$1.59 \pm 0.12$$ 1.59 ± 0.12 sievert during solar maximum and minimum periods, respectively. The shielding of the GCR radiation by heliospheric magnetic fields during solar maximum periods is rather efficient in reducing the total GCR-induced radiation for a Mars mission, by more than 50%. However, further contributions by SEPs must also be taken into account. In the future, with advanced nuclear thrusters via a fast transfer, we estimate that the total GCR dose equivalent can be reduced to about 0.2 sievert and 0.5 sievert during solar maximum and minimum periods respectively. In addition, we also examined factors which may further reduce the radiation dose in space and on Mars and discuss the many uncertainties in the interpreting the biological effect based on the current measurement.

Fuga e ritorno: Italian-Canadian Narratives

Many Italian-Canadian authors have been stimulated to explore their dual identity after a return trip to Italy. They confront the myth of nostalgia as an emotional blind-spot to the harsh realities of past miseria and present-day conflicts in Italian society. Women writers such as Mary di Michele, Caterina Edwards, Licia Canton and Rina Cralli are particularly critical of the position of women in Italy and the whole nostalgia sentimentality promoted by Italian popular culture and music. Pasquale Verdicchio’s whole writing career has been a systematic rejection of the thematics of nostalgia.

Transportation efficiency in eighteenth-century merchant vessels

A key ingredient in New England’s shipping successes was the speed with which its vessels completed their voyages. The principle research on this subject was completed by Gary Walton and published in its first form in 1967. Walton was ahead of his time in identifying the importance of a detailed study of colonial shipping and linking it to a broader Atlantic World. He draws several conclusions. First, that technological change between 1675 and 1775 was minimal in the industry. Second, costs and crew sizes declined due to increases in security after the Royal Navy eliminated piracy. Third, idle time in port decreased, leading to more efficiencies in acquiring cargo. Fourth, and finally, vessel speeds were stagnant throughout the period and were 1.6 to 1.97 knots for the voyage south between New England and the West Indies and 1.31 to 2.09 knots for the return trip. Averages calculated by Walton indicate speeds of between 1.6 and 1.8 knots, with the southbound legs slightly faster. I agree with Walton on all of his conclusions except for the last. Careful study of 145 logbooks chronicling the voyages of Massachusetts’s vessels in the West Indies trade indicates that the median vessel speed over the approximately 1,500 nautical miles from Boston to the islands was 2.71 knots and the mean speed approached 2.84 knots. In fact, the median southbound speed was five per cent slower than the trip home. In practical terms, this meant that according to Walton the time it took to travel 1,500 nautical miles averaged a minimum of almost 35 days. According to the logbooks, however, merchant mariners completed voyages between New England and the West Indies in slightly more than 25 days on average, 28 per cent faster than Walton figured.

Alexander von Humboldt (1769–1859): early high-altitude explorer and renowned plant naturalist

Alexander von Humboldt (1769–1859) was one of the most distinguished German scientists of the late 18th and early 19th centuries. His fame came chiefly from his extensive explorations in South America and his eminence as a plant naturalist. He attempted to climb the inactive volcano Chimborazo in Ecuador, which was thought to be the highest mountain in the world at the time, and he reached an altitude of about 5,543 m, which was a record height for humans. During the climb, he had typical symptoms of acute mountain sickness, which he correctly attributed to the low level of oxygen, and he was apparently the first person to make this connection. His ability as a naturalist enabled him to recognize the effect of high altitude on the distribution of plants, and by comparing his observations on Chimborazo with those in the European Alps and elsewhere, he inferred that the deleterious effects of high altitude were universal. During his return trip to Europe, he called on President Thomas Jefferson in Washington, where he was given a warm reception, and discussed conservation issues. He then returned to Paris, where he produced 29 volumes over a period of 31 years describing his travels. Here the effects of high altitude on the distribution of plants compared with animals are briefly reviewed. Following Humboldt’s death in 1859, there was extensive coverage of his contributions, but curiously, his fame has diminished over the years, and inexplicably, he now has a lower profile in North America.

To Jerusalem

Chapter 8 depicts the voyage to and settlement in Jerusalem, with a stop in Alexandria and surroundings, to meet bishops and holy men. On a return trip to Egypt, they visited the so-called desert fathers and attempted to leave them funds. Egypt and Palestine (called the “Holy Land” by Christians in this era) were the prime destinations for Christian pilgrims, women as well as men, from the fourth century onward. Some “Westerners” settled there and founded monasteries, including Melania’s own grandmother and other Roman aristocrats. The Bible provided a virtual tour guide for pilgrims in Palestine. The family of Constantine saw to the erection of the churches of the Holy Sepulcher in Jerusalem and of the Nativity in Bethlehem. Accompanying these developments was the burgeoning quest for relics (of the “True Cross,” of the body parts of martyrs and saints). Melania, too, sought relics for the monasteries she established in Jerusalem. For some years before undertaking the building of monasteries and soliciting inhabitants for them, however, she lived in semi-solitary confinement on the Mount of Olives. The author of the Life describes the ascetic practices in these establishments. After the monasteries were built, there is little evidence that Melania participated much in the larger worship life of Jerusalem, which is described in other sources. The author of the Life aligns his heroine with his own religious preferences and depicts her as a fierce opponent of “heresy.”

Autoficción e identidades híbridas en Bélgica de Chantal Maillard y Ni d’Ève ni d’Adam de Amélie Nothomb

"This article aims to establish a comparative analysis of two works by migrant authors, Bélgica (2011) by Chantal Maillard and Ni d’Ève ni d’Adam (2007) by Amélie Nothomb. Both authors reflect upon national identity through the return trip to their native countries. This reflection is directly linked to the complicated Belgian identity (referred to in the literature as a hybrid, mestizo or absent identity), since the former returns to Belgium from Spain, and the latter escapes from it to return to Japan. From the methodology of Comparative Literature we will study how both, Maillard in the self-essay and Nothomb in the autofictional novel, will attend to the very concept of writing and its questioning as an identity trait"
