  1. A blogged complaint Vor einer Weile hab ich mich, trübsalblasend, darüber beschwehrt, dass niemand[2] mehr interesse an Chemie hat. Die Medien ignorieren uns. Ich habe eine sterbende Wissenschaft studiert. Et cetera. SO hatte Mitleid mit mir und hat mir exact ausgelegt das ”alles ist Chemie, es heißt nur anders.” Wir haben eine Liste gemacht und mein lieblings Euphemismus war Materialdesign. Ehrlich, welche Werkzeuge willst du verwenden um ein Material zu designen, wenn nicht die der Chemie. Siehste?!Egal, ich möchte euch eine schöne letzte Woche vor den Ferien wünschen (wenn ihr welche habt) und ich möchte bekanntgeben das ich nicht mehr Chemikerin bin sondern ein “molecular designer, the profession formerly known as chemist” .... www.hdreioplus.de/wordpress/?tag=Chemistry

  2. Thank you for inviting me

  3. Selling Chemistry With a Sample Case- Chemists see molecules dance - Leo Gros Europa Fachhochschule Fresenius Idstein Germany

  4. Can we sell chemistrywithout being spectacular? We have to, because chemistry needs imagination (Huisgen)– let us nourish it!

  5. What is the difference between chemists and all other people? Chemists see molecules bounce, run, collide – and dance where and when other people see everyday life – or nothing... Let us accompany a chemist during a normal day – with a chemist‘s eyes and brains 8 observations wait for us

  6. 1. Early morning: The alarm clock rings A „digital display“ shows him/her the hour

  7. Intervention from industry „It is most astonishingly the high „technology content“ of everyday life that decreases interest in technical studies: everybody can operate a mobile phone or an MP3 – but few have an idea how it works. Technology becomes self-understood, and at the same time a black box.“ Volker Brenneke, Bildungsabteilung VDI , Interview in DER SPIEGEL 50/2006

  8. An unexpected observation .... which we can now share

  9. 1970: A patent .... and a publication: M. Schadt, W. Helfrich, Voltage Dependent Optical Activity of a Twisted Nematic Liquid Crystal Appl. Phys. Lett. 19, 127 (1971)

  10. Chemists see molecules dance

  11. .... and a rubber band stretches 2. The chemist gets out of his pyjamas....

  12. This is what the chemist sees.....

  13. .... and this is what became an unexpected toy invention Early in World War II, James Wright was working in General Electric's New Haven, Connecticut labs, under a government contract to create an inexpensive substitute for synthetic rubber. One day in 1943, Wright happened to drop boric acid into silicone oil, and was astonished to find that the resultant goo would stretch and bounce further than rubber, even at extreme temperatures. In addition, the substance would copy any newspaper or comic-book print that it touched. ... which we will now observe in action... and observe further

  14. An apple for breakfast – and simplified view of a brilliant mind Szent-Györgyi (1925) – observation/ideas: patient -------------------- brown skin (adrenalopathy) polyphenol oxidase apple ------------------------apple (just cut) (brown) citrus fruit juice apple ------//------------apple (just cut) acids (brown) .... which we can share today

  15. .... and his words in the Nobel Lecture 1937

  16. ... as a chemist, he tries to isolate an active substance…. „It was an acid, it seemed to be derived from an unknown sugar which I called „Ignose“ , the substance itself I called „Ignosic acid“. But the editor of the journal to whom I sent my publication did not like what he called a joke and rejected the name. „Godnose“ was not successful either, therefore we agreed that the child ought to be baptised hexuronic acid. Later on, with advanced knowledge about the structure, it had to be renamed hastily and now it is called ascorbic acid (sometimes Vitamin-C-acid), since it is identical to Vitamin C and prevents scurvy. That's how I became a father without having intended it, father of the Vitamin C.“

  17. This is how chemists see the action of lemon juice: http://www.gartendatenbank.de/photo/2004012583 ….ascorbic acid inhibits polyphenoloxidase http://www.fao.org/ag/Ags/agsi/ENZYMEFINAL/Enzymatic%20Browning.html#ASCORB

  18. A Nobel Prize Winner’s conclusion

  19. 4. Chicken soup for lunch …. the chemist as a food detective www.schule-bw.de/unterricht/faecher/biologie/archiv/tiere/voegel/Huhn2.jpg/view

  20. Simple forensic chemistry

  21. This is how chemists describe the phenomenon of the red light: http://www.ieap.uni-kiel.de/plasma/ag-stroth/lehre/physik/HTML/f40_08.html

  22. Based on this phenomenon, Bunsen and Kirchhoff developed an analytical technique: flame emission spectroscopy http://lims.uni-duisburg.de/Lehre/Material/PMAll/vorproben.pdf

  23. This is how chemists measure calcium in blood or soil samples

  24. 5.Lemonade in the afternoon - and three times NaHCO3 + C6H8O7 → NaC6H7O7 + H2O + CO2 H3O+ + HCO3- → H2CO3 + H2O → CO2 + 2 H2O • Brause (sherbet) • Schorle (spritzer) • baking powder effervescence ….. …chemists recognize the „underlying principles“ and thus classify, i.e. simplify http://de.wikipedia.org/wiki/Brausepulver

  25. .... and understand stalactite and scale formation as well

  26. 6. Evening meal with healthy garlic – anda story taking place at the Auer Dult near Munich Observe with me the wonderful anti-poison activity of garlic extract – and of wine! http://www.gartendatenbank.de/photo/2004012583

  27. Alliin   Allylsulfensäure    alpha-Aminoacrylsäure Allylsulfensäure                                             Allicin That’s only one feature of the „chemistry“ of garlic Alliin ((+)-(S)-Allyl-L-cysteinsulfoxid) http://www.uni-bayreuth.de/departments/ddchemie/umat/knoblauch/knoblauch.htm#1

  28. An example of a chemical reaction using permanganate: (Determination of oxalic acid) http://www.chemie.uni-greifswald.de/~analytik/Lehre/Schr%F6der/Quanti/Wasserg%FCte.pdf

  29. Water pollution in the Elbe river at the beginning of the 20th century. http://www.springerlink.com/content/k85400x365p3q37h/fulltext.pdf

  30. A very recent publication tells us more… Here we show that human RBCs convert garlic-derived organic polysulfides into hydrogen sulfide (H2S), an endogenous cardioprotective vascular cell signaling molecule…. The vasoactivity of garlic compounds is synchronous with H2S production, and their potency to mediate relaxation increases with H2S yield, strongly supporting our hypothesis that H2S mediates the vasoactivity of garlic. Gloria A. Benavides et al., http://www.pnas.org/cgi/content/abstract/0705710104v1

  31. 7. Evening pleasure: the chemist takes a bath… ...observes dirty whitish flakes on the bathtub surface after letting the water go down the drain… ...and has to clean the tub like everyone else… http://www.uni-essen.de/chemiedidaktik/S+WM/NachteileSeife/Wasserh.htm

  32. …but he or she sees the molecules dance… http://de.wikipedia.org/wiki/Tenside

  33. This way chemists see surfactant salts: - Ca 2+ -

  34. 8. The chemist‘s baby needs diapers...

  35. Not a secret: diapers contain an astonishing powder..... Super-absorbent particles before (left) and after absorbing water The super-absorbent – a white powder 1g of polymer absorbs up to 1000g of water

  36. Chemists must see molecules

  37. Imagination – a professor’s imagination – is it true that molecules dance?

  38. http://www.physics.ubc.ca/~stm/news0229.pdf

  39. How chemists see the world … they see molecules dancing where other people see nothing …and that is our benefit: We understand our world better – we can make substances, transfer and measure them – and we learn about dangers and benefits of our actions

  40. I thank my students, here represented by Sascha and Noreen, 3rd semester

  41. Limits and Dreams Education is an admirable thing, but it is well to remember from time to time that nothing that is worth knowing can be taught. Oscar Wilde (The Critic as Artist) * You see things and say: “Why?” But I dream things and say “Why not?” G.B. Shaw, John Bull’s Other Ireland (on a poster in Dublin airport)

  42. Can we teach without being spectacular? Yes, we can, we must inspire imagination....

  43. „Die große Regel: Wenn Dein Bißgen an sich nichts Sonderbares ist, so sag es wenigstens ein bißgen sonderbar!“ G.C. Lichtenberg (Sudelbücher E [243]) The golden rule: If your bits and pieces have nothing special, then at least present them in a special way!
