Erwin Chargaff cytaty

Erwin Chargaff – biochemik austriacki, badacz DNA.

Urodził się w Czerniowcach w Księstwie Bukowiny. W latach 1923–1928 studiował chemię w Wiedniu, następnie dwa lata w Yale. Od roku 1930 pracował na Uniwersytecie Berlińskim, przeniósł się do Pasteur Institute w Paryżu w 1933 r. W 1935 r. wyemigrował do Nowego Jorku i został profesorem Columbia University.

Jest autorem praw dotyczących zawartości zasad azotowych w DNA, nazwanych później regułami Chargaffa. Wykazał też, że kompozycja zasad DNA różni się pomiędzy gatunkami, czyli stosunek / jest różny u różnych gatunków. Umocniło to hipotezę o DNA jako materiale genetycznym w komórkach.

Erwin Chargaff: Cytaty po angielsku

“Now one could say, at the risk of some superficiality, that there exist principally two types of scientists. The ones, and they are rare, wish to understand the world, to know nature; the others, far more frequent, wish to explain it. The first are searching for truth, often with knowledge that they will not attain it; the second strive for plausibility, for the achievement of an intellectually consistent, and hence successful, view of the world.”

“In 1945, therefore, I proved a sentimental fool; and Mr. Truman could safely have classified me among the whimpering idiots he did not wish admitted to the presidential office. For I felt that no man has the right to decree so much suffering, and that science, in providing and sharpening the knife and in upholding the ram, had incurred a guilt of which it will never get rid. It was at that time that the nexus between science and murder became clear to me. For several years after the somber event, between 1947 and 1952, I tried desperately to find a position in what then appeared to me as a bucolic Switzerland,—but I had no success.”

“Outside his own ever-narrowing field of specialization, a scientist is a layman. What members of an academy of science have in common is a certain form of semiparasitic living.”
