1 NOTES FROM THE HISTORY OF SCIENCE M. Tomak

2 GEORGE SARTON “History of civilization is the history of science. The reason lies in the fact that the main difference between today’s civilization and the antiquity is the scientific knowledge. Saints of today are no different than the ancient ones. Today’s artists are no more skillful than the ancient ones.”

3 GEORGE SARTON “But the knowledge of our scientists is much more and deeper. So, one of the most cumulative human activity is science. Thus, the most important difference between the two civilizations is in the levels of the scientific knowledge.”

4 Times Nicolas Copernicus De Revolutionibus : Copernicus1543 Tycho Brahe Galileo Galilei William Shakespeare Johannes Kepler Isaac Newton

5 Nicolaus Copernicus Scientific Revolution

6 Sun Centered System Collected Observations (Zic: Astronomic almanac)

7 Giordano Bruno ( ) Supported Copernicus, “Libertes philosophica”, supported free thinking, Burned in Rome.

8 Enlightment Starts with Kepler: Born,27 Dec.1571 near Stutgart, Lutheran, studied theology inTübingen University to be a priest but perfect in mathematics and astronomy. Johannes Kepler ( )

9 KEPLER Instead of becoming a priest, accepted a position as teacher of mathematics and Astronomy in Graz,Austria (later Graz University) ( ).

10 KEPLER Universe is an image of God. Tycho Brahe (who corrected Copernicus-zic by careful observations) invited him to Prag on Jan. 1,1600 ( ). Brahe died on 24 Oct., Kepler takes his position and data, and starts to work on the trajectory of Mars.

11 Freedom of the Mind! Works on Mars data till After 5 years in vain, abondons the idea of church, that favors circular orbits, And discovers elliptical orbits!

12 GALILEO GALILEI ( ) Galileo Galilei, observes Jupiter’s moons in University of Padua(1610), with his telescope, contrary to the views of the church. Supports Copernicus, Does experiments on the motion of objects. Galileo Galilei( )

13 GALILEO “You cannot learn physics from the holly books. You have to do experiments for this. You can only learn how to be a good person.”

14 Scientific Revolution 1543 Copernicus, 1609, 1619 Kepler, 1610 Galileo, 1620 Bacon 1637 Descartes, 1686 Newton 150 years, to abolish 2000 years old Aristoteles-Physics,Ptolemaios- Astronomy,İbn-i Sina – Medicine.

15 Scientific Revolution is continuing.... Nano-science today LHC

16 The year(s) of the nano

17 Friction of Molecules Micromachines gearing up? Microscopic gears may stick or grind to a halt because of novel kinds of friction at the molecular level. A. R. Burns, J. E. Houston, R. W. Carpick, and T. A. Michalske Phys. Rev. Lett. 82, 1181 (issue of 8 February 1999) Phys. Rev. Lett. 82, 1181

18 Reducing Friction without Oil Phys. Rev. Lett. 92, (2004) Hair trigger. The "Tribolever" device can sense atomic scale forces on its tip in all three dimensions. Tribolever experiments demonstrated a regime of extreme slipperiness between the tip and surface

19 How to Grab an Atom Phys. Rev. Lett. 90, (2003) Now you see it, now you don't. Researchers used the tip of an atomic force microscope to lift a single atom from a surface (above, before and after) and then replace it (not shown). The method works with non- conducting materials, unlike past atom manipulation techniques.

20 The Magic of Nanoclusters Phys. Rev. Lett. 88, (2002) Clusters everywhere. Billions of identical metal clusters can spontaneously form on a silicon surface. Each triangle contains six indium atoms. (With more indium, the clusters fill in some of the empty space, making complete rows and columns of triangles.) The nanoclusters may be useful for electronic devices, for data storage, or for fostering chemical reactions.

21 Nanocrystals Phys. Rev. Lett. 84, 951 (2000) Air-cleaning crystal. The first atomic-scale images of nanocrystals that help reduce pollution show a surprising triangular, rather than hexagonal, shape. The new information should help researchers improve the chemical process

22 NANO-BALANCE The atom at the tip of a nanotube is changing the vibrational frequency of the tube.

23 Molecular Conductivity Takes Shape Phys. Rev. Lett. 88, (2002) Mind the gap. By breaking a tiny gold bridge (shown in false color), researchers make electrodes for driving current through a single molecule. Now they have shown a specific way in which the molecule's shape affects its conductivity.

24 24 Fullerenes The fullerenes are a family of molecules with a closed cage of carbon atoms arranged in pentagons and hexagons. Each carbon is sp 2 hybridized. –The most symmetrical member is buckminsterfullerene, C 60. –Buckminsterfullerenes show potential for applications in superconductivity and catalytic activity.

25 25 A frame model of C 60. By permission of Dr. Richard Smalley, Rice University Buckminsterfullerene

26 Nanotube Electronics Chips made from tubes.Appl. Phys. Lett. 74, 79 (1999) Chips made from tubes. Adding atoms (blue and red) to an all- carbon nanotube makes the nanoworld equivalent of a semiconductor junction--the basis for computer chips

27 Nanotubes Under Stress Hande Ustunel/Cornell Univ. Springy Nanotubes. A carbon nanotube, when pressed in the middle, will stretch like a rubber band. According to experiments, the stretching modifies the quantum states available to electrons, which alters the nanotube's electrical resistance.

32 As Science was developing in the West, what was happening in the Islamic World?

33 MADRASAH University in Islamic World First: in Buhara 937, Faracek, 1067 Bağdat: Nizamiye medreseleri, 13th century Selçuk: Konya, Sivas, Kayseri,whole anatolia, Ottoman: 1331 İznik,Bursa, Edirne, İstanbul

34 Madrasah:Curriculum Ulum-u Nakliye: fıkıh, hadis, kelam, tefsir Ulum-u Akliye: matematik, astronomi,

35 University in the West 1088 Bologna, 1160 Paris, 1167 Oxford, Montpellier, Padua, Orleans, Cambridge North : Prag(1347), Karakov(1364), Viyana(1365), Heidelberg(1385), Kopenhag (1475), Uppsala(1477) No similar development towards east...Byzantium ?

36 University:Curriculum Trivium: (Rhetoric, Logic, Gramer); Quadrivium: (Arithmetics- Geometry, Physics, Astronomy, Music)

37 Madrasah in Turkestan Great men of science at the beginning: Farabi( ), İbn-i Sina (Avicenna) ( ).

38 Something goes wrong!

39 İMAM GAZALİ ( ) His book: “Tehafüt-ül Felasife: Felsefenin Tutarsızlığı”,Philosophy is not useful, Everything is in Quran. No need to do any research.

40 İBN-İ RÜŞD (AVERROES) ( ) His book: “Tehafüt-ül Tehafüt: Tutarsızlığın Tutarsızlığı”. In Spain, Averroes critisizes Gazali; “Using your mind, you can reach the truth and the religous belief.” West, prospers along İbn-i Rüşd’s philosophy. But Madrasah goes along with İmam Gazali.

41 Should we include İBN-İ RÜŞD ideas? Question comes from the great conqurer.

42 The Result of the Discussion Everybody says “Gazali”, including his own teacher (Hocazade Efendi), except Alaaddin from Tus, who favors İbn-i Rüşd. Ottoman Madrasah keeps teaching only Gazali.

43 AND THE RESULT...

44 LÜTFİ from TOKAT A teacher at madrasah, during the reign of Beyazıt II, is quoted saying: “Those who do not know geometry, can not judge correctly” He is judged, in a tribunal under the presidency of “Sheikh ul-Islam ” and, He is hanged Dec. 24,1494 at “At Meydanı”.

45 EBU SUUD EFENDİ Sheikh ul-Islam between 1545 –1574, He is instrumental in Sultan Süleyman’s receiving the title of Kanuni. He is trying to establish the state’s justice systemin a scientific manner.

46 MEHMED from BİRGİ In the same period, Mehmed Efendi from Birgi, is in favor of returning to the basics of islam. He divides the sciences into two groups. “Useful” which is the teachings of islam. “Harmful”all positive sciences and logos(kelam). All madrasahs are under Sheikh ul-Islam.

47 TAKİYUDDİN OBSERVATORY Müneccimbaşı Takiyyüddin (B: 1526 Egypt) convinces Murat III, to build an observatory on the hills of Tophane in1577. A student of Birgili, Sheikh ul-Islam Kadızade, using the appearence of a comet, and epidemy of plague starting at 1578, convinces the Sultan that this is a result of watching the skys. Observatory is demolished on 22 Ocak A real start of going backwards.

48 RESULT This starts our dark ages that includes: 16th 17th centuries and the first half of 18th century.

49 MILITARY DEFEATS Russian navy destroys Ottoman navy in Çeşme in The attack is being expected from the Black Sea, nobody checks the map of Piri Reis.

50 AWAKENING After only the defeats of this order, the reason is found as the lack of knowledge. This brought the need for new establishments. The first educational institute established is Mühendishane–i Bahri–i Hümayun in1773, which is the base of today’s İstanbul Technical University. The curriculum in this navy school was basically the natural sciences.

51 DARÜLFÜNUN I in the Ottoman Empire Reform and reorganization (İslahat ve Tanzimat) starts. Darülfünun is established on July 23, But it failed due to lack of interest on the part of students.

52 DARÜLFÜNUN II "Darülfünun-u Osmani" is established on February 20, But this time it was the inedaquacy of the teaching staff and books that caused the closure in 1872.

53 DARÜLFÜNUN III Darülfünun-u Sultani is established at Galatasaray in 1874, with Literature, Law, and Science Departments. The lectures were in Turkish and French. There is no information about this institution after 1881.

54 DARÜLFÜNUN IV Darülfunun-u Şahane (İmparatorluk Üniversitesi) is established September with departments of religion, mathematics and literature. Under heavy scuritiny of the the Empire, it was not successful.

55 DARÜLFÜNUN V Meşrutiyet (constitutional Monarchy) is declared. İstanbul Darülfünun is then established on April 20, 1912, with departments of Law, Medicine, Literature and Religion. But, it had the form of a madrasah, rather than a modern University..

56 TURKISH ENLIGHTMENT

57 ATATÜRK Dünyada herşey için, hayat için başarı için en gerçek yol gösterici bilimdir, fendir. Bilim ve fenin dışında yol gösterici aramak gaflettir,cahilliktir, doğru yoldan sapmaktır. Bilim ve fen nerede ise oradan alacağız ve her millet ferdinin kafasına koyacağız.

58 Akıl ve bilimi rehber alınız Ben, manevî miras olarak hiçbir ayet, hiçbir dogma, hiçbir donmuş ve kalıplaşmış kural bırakmıyorum. Benim manevî mirasım bilim ve akıldır. Benden sonra, beni benimsemek isteyenler, bu temel eksen üzerinde akıl ve bilimin rehberliğini kabul ederlerse manevî mirasçılarım olurlar.

59 ÖĞRETMENLER Hiçbir zaman hatırlarınızdan çıkmasın ki, Cumhuriyet, sizden fikri hür, vicdanı hür, irfanı hür nesiller ister

60 1933 University Reform Atatürk’s notes on Prof. Albert Malche report( ) Students should know foreign languages, President of the University should be concerned with scientific matters. An administrator is needed for administrative business. The weakest point in Darülfünun is the education that is not cultivating research skills in students., Library should be improved.

61 İSTANBUL UNIVERSITY 1933 Law No abolishes Darülfünun and establishes a new İstanbul University. Istanbul University is thus the first university of the young Republic which opened on August 1, As the Republic celebrates the 10th anniversity, academic year starts in the new university on November1,1933.

62

63 Prof. Albert Malche was asked to recruit new faculty members from Europe.

64 Einstein’s Letter At September 17, 1933 letter from Einstein to Prime Minister Ismet Inonu pleaded for Turkey to invite "fourty experienced specialists and prominent scholars... to settle and practice in your country."

65

66 Andreas Bertholan Schwarz ( ) He was a professor of Roman and Civil Law at the University of Leipzig. He then transferred to the University of Zurich and in 1929 moved to the University of Freiburg from which he was dismissed in He immigrated to Turkey in 1934 and was appointed as professor in the same field at the Law Faculty of the University of Istanbul where he remained until 1950 when he became guest professor at the University of Freiburg. Schwarz died in Freiburg in By advising parliamentary commissions and submitting several memoranda for the required changes, he played a significant role in modernizing Turkey’s civil laws during the 1930s,which brought a deep-rooted progress. He trained an entire generation of Turkish legal scholars.

67 Ernst Eduard Hirsch ( ) came to Turkey in 1933 after being dismissed from the University of Frankfurt am Main and declining an offer from the University of Amsterdam, which probably saved him from Nazi persecution when Germany invaded Holland.

68 Fritz Neumark was born in 1900 in Hanover, Germany.Among the four émigrés he was perhaps the most important contributor to the modernization of Turkey’s public sector. He was dismissed from the University of Frankfurt on September 1, 1933 and left Frankfurt on September 22 of the same year. He went to Switzerland and in the presence of the Turkish Ambassador Cemal Hüsnü in Geneva signed a renewable five-year contract (October 15, 1933 to October 15, 1938) to teach social hygiene and statistics.

69 We owe a lot to these scholars...

70 Are products of the new Republic, not a continuation of old Darül-fünun. Modern Turkish Universities

71 I hope I have shown that events do not happen in an arbitrary manner, but that they reflect a certain underlying order...

72 WHAT SHOULD WE DO?... A civilization in Turkey that does not rely on science cannot compete with the representatives of modern civilization...

73 What should we do? Educating yourself is your own responsibility. We should work hard and with love, to educate ourselves in our fields of specialization, We should take our education seriously, trying to be world class scholars, We should enlighten ourselves, by not graduating solely as technicians. We should support our universities.

74 Everybody should be science-literate.... Scientific thinking...

75 Social Sciences are also very important.... Enlightened graduates.

76 OYP is important! GOOD LUCK!
