First printing of 5 importent papers containing substantial contributions to the development and understanding of the fission process in the crucial year 1939, the results leading to the creation the atomic bomb and nuclear energy production. Among the papers here are Francis Perrin's landmark paper: "Calcul relatif aux conditions éventuelles de transmutation en chaine de l'uranium." (in 2 parts).Nuclear fission of heavy elements was discovered on December 17, 1938 by Otto Hahn and his assistant Fritz Strassmann, and explained theoretically in January 1939 by Lise Meitner and her nephew Otto Robert Frisch. The Group at College de France, headed by Joliot and Perrin, worked in the month after January intensively with the uranium processes and succeeded in establishing the possibility of nuclear chain reactions and nuclear energy production."The remaining piece of the fission/atomic bomb concept was provided in 1939 by Francis Perrin who introduced the concept of the critical mass of uranium required to produce a self-sustaining release of energy. His theories were extended by Rudolf Peierls at Birmingham University and the resulting calculations were of considerable importance in the development of the atomic bomb. Perrin's group in Paris continued their studies and demonstrated that a chain reaction could be sustained in a uranium-water mixture (the water being used to slow down the neutrons) provided external neutrons were injected into the system. They also demonstrated the idea of introducing neutron-absorbing material to limit the multiplication of neutrons and thus control the nuclear reaction (which is the basis for the operation of a nuclear power station)."

Pfullingen, Günter Neske, (1954). 8vo. Original full black cloth with white lettering to spine. Very clean, bright, and fresh, also internally. Original orange dust-jacket with black lettering to spine and white lettering to front. Minimal edge wear. An excellent and clean dust-jacket with just minor signs of wear. Very slight soiling to title-page, otherwise no wear or markings to text. Letter from Heidegger inserted to inside of front board. Front free end-paper signed and dated by Heidegger and with an inserted note in ink from the person that Heidegger gave the book to stating that this highly personal memento from his student time in Freiburg and his memorable encounters with Heidegger was given to his son Matthias for his 40th birthday, in 1995. 283, (1) pp. First edition, presentation-copy signed by Heidgger and with an inserted letter, also signed and dated by Heidegger, of this seminal collection of lectures and essays, which was of decisive importance to the immense influence of Heidegger’s thinking upon post World War Europe. This collection of Heidegger’s lectures and essays contains such groundbreaking works as “Die Frage nach der Technik” (The Question Concerning Technology) and “Wissenschaft und Besinnung” (Science and Reflection), “”Dichterisch Wohnet der Mensch…” “, along with other important works written between 1936 and 1953 collected here for the first time. This collection would later be reprinted and serve as volume 7 of Heidegger’s collected works (the Gesamtausgabe). This copy is signed “Martin Heidegger” and dated (1954 – the year of publication) to the front free end-paper, and on the inside of the front board is inserted an autograph signed letter in Heidegger’s hand to “Sehr geehrter Herr Doktor” (honourable doctor), in which Heidegger asks to meet up the following day, suggesting different times of the day. The letter is dated Freiburg 10th of February, 1954, which is two days before Heidegger gave his groundbreaking lecture “The Question Concerning Technology” at the University of Freiburg, suggesting that the letter was given to someone attending the lecture, possibly someone with whom he wanted to discuss it beforehand. “The Question Concerning Technology” still serves as one of the most pertinent philosophical essays of modern time, foreshadowing what is arguably the greatest philosophical and moral dilemmas that we struggle with today due to modern technology. Heidegger begins with asking the question what technology is, in an attempt to fully understand its essence and to ultimately prepare a free relationship to it – a theme that could hardly be more relevant today. “As relevant now as ever before, this accessible collection is an essential landmark in the philosophy of science from one of the most profound thinkers of the twentieth century (New York Times). The advent of machine technology has given rise to some of the deepest problems of modern thought. Featuring the celebrated essay The Question Concerning Technology, this prescient volume contains Martin Heidegger's groundbreaking investigation into the pervasive enframing character of our understanding of ourselves and the world.” (Harper Collins: The Question Concerning Technology And Other Essays By Martin Heidegger, 2013). “Science and Reflection” (here published for the first time), a lecture delivered on August 4, 1953, to a small circle of attendees, is Heidegger’s meditation on the difference between science and “mindfulness”, and an as-relevant-as-ever attempt at uniting science as such, in itself, with its application and meaning, combatting scientific fragmentation. In line with the other foreshadowing lectures, “Dichterisch wohnet der Mensch”, given on October 6, 1951, in Bühlerhöhe, seeks to explore how to reach a peace or dwelling in a modern, technological world. Heidegger uses the quote by Hölderlin to explore how human existence is deeply intertwined with language and poetry and reaches the conclusion that to truly dwell is to live in a poetic way, allowing for the meaningful unfolding of the world through language. The other essays/lectures printed in this seminal volume are: Überwindung der Metaphysik (1936-1946) Wer ist Nietzsches Zarathustra (1953) Was heißt Denken? (1952) Bauen Wohnen Denken (1951) Das Ding (1950) Logos (Heraklit, Fragment 50) (1951) Moira (Parmenides, Fragment VIII, 34-41) (1952) Aletheia (Heraklit, Fragment 16) (1954)
