Israeli Scientist Wins Nobel Prize for Chemistry


By KENNETH CHANG

Published: October 5, 2011

An Israeli scientist won this year’s Nobel Prize in Chemistry for discovering a material in which atoms were packed together in a well-defined pattern that never repeats.

Recent Nobel prizes have generally split credit for scientific advances among two or three people, but this year’s chemistry prize and accompanying 10 million Swedish kronor ($1.4 million) went to a single scientist: Daniel Shechtman, 70, a professor of materials science at Technion - Israel Institute of Technology.

The citation from the Royal Swedish Academy of Sciences states simply, “for the discovery of quasicrystals.”

Such regular but non-repeating patterns, defined by precise rules, have been known in mathematics since antiquity and are found in mosaics of medieval Islamic tiles, but it was thought impossible in the packing of atoms.

Dr. Shechtman discovered the same type of structure while studying a metal mix of aluminum and manganese. His notebook recorded the exact date: April 8, 1982.

Scientists believed that crystals in materials all contained repeating patterns, and Dr. Shechtman took years to convince others. During the announcement, the Nobel committee noted that one colleague said, “Go away, Danny” and that he was even asked to leave his research group.

Quasicrystals have since been found in many other materials, including a naturally occurring mineral from a Russian river.

The guy did a great job, aling'ang'ania mpaka akapata. Ni somo zuri kwa researchers wote kuwa it takes a time to get a convincing result of your work.

Ooh!now i knw that in some chemical materials, crystals can hv unrepeatedly patterns!good work

nimeisoma pia bbc, ila hawa jamaa kama mchangiaji mmoja alivyosema wana courage na determination ambayo yaweza kwenda hata kutoka kizazi kimoja hadi kingine but "giving up" hawataki kabisa!
Hope nasi tungelianza kujifunza na kujitune on those virtues badala ya kukata tamaa na kutoamini ukweli wa mambo

... His notebook recorded the exact date: April 8, 1982.*
What a patience ... !! You can*imagine*what challenges he*overcomed ... to come up with final last solid result*... *negative resistances, doubts, ups and downs, betrayals etc *... But he stood up on what he believed ... without paying much*attention*on time, if it wont come out true, if it wont pay...etc quick fix to him? ... no it*didn't*apply .. a real*research*material*isn't*it?l!!

Nchi ikitaka kuendelea, lazima itenge taasisi kama hizi ambazo hazitakuwa zinaingiliwa na wanasiasa. It should be the backbone of the country,watu wanadocument madude toka alipojua integral hadi anazeeka, na hiyo ni kazi kubwa ya waalimu. Waalimu wana impact kubwa sana kwenye jamii, kama mwalimu akiamua kuhubiri watoto kukichukia kitu basi hao watoto watakuwa hivyo hivyo kwa muda mrefu hadi pale watakapoamua kutafuta ukweli.

Na ndivyo wanavyofanya wenzetu, smart people go for teaching and research posts, wanawezeshwa kila kitu na kujikuta wanafanya kazi zao kwa kuenjoy bila kuwa stressed.
