🏅Nobel Lectures (1930-1939)

"More than one way for doing the same thing is provided by the natural constitution of the nervous system. This luxury of means of compassing a given combination seems to offer the means of restitution of an act after its impairment or loss in one of its several forms." (Charles Sherrington, "Inhibition as a Coordinative Factor", [Nobel lecture] 1932) 

"To get an interpretation of some modern experimental results one must suppose that particles can be created and annihilated. Thus if a particle is observed to come out from another particle, one can no longer be sure that the latter is composite. The former may have been created. The distinction between elementary particles and composite particles now becomes a matter of convenience. This reason alone is sufficient to compel one to give up the attractive philosophical idea that all matter is made up of one kind, or perhaps two kinds of bricks." (Paul A M Dirac,"Theory of Electrons and Positrons", [Nobel lecture] 1933) 

"A living cell requires energy not only for all its functions, but also for the maintenance of its structure. Without energy life would be extinguished instantaneously, and the cellular fabric would collapse." (Albert Szent-Györgyi,"Oxidation, Energy Transfer, and Vitamins", [Nobel lecture] 1937) 

"The goddess of learning is fabled to have sprung fullgrown from the brain of Zeus, but it is seldom that a scientific conception is born in its fi nal form, or owns a single parent. More often it is the product of a series of minds, each in turn modifying the ideas of those that came before, and providing material for those that come after. The electron is no exception." (George P Thomson,"Electronic Waves", [Nobel lecture] 1937)

"Although the problem of transmuting chemical elements into each other is much older than a satisfactory definition of the very concept of chemical element, it is well known that the first and most important step towards its solution was made only nineteen years ago by the late Lord Rutherford, who started the method of the nuclear bombardments.” —  Enrico Fermi, [Nobel lecture] 1938)
