NEWSLETTER - 6 JULY
|Feature for Today |
|On 6 July 1817, Rudolph von K�lliker was born, one of the founders of embryology. With pioneering microscopic work on tissues, he identified the cell structure of tissues, that nerve fibres are elongated cells, and the cellular form of the egg and sperm. He also suspected that the cell nucleus was involved in heredity, but it was for others who came later to unravel that mystery. For much more background, read his obituary in the British Medical Journal, Rudolph Albert von K�lliker from 1905.|

|Quotations for Today|
| ||"I am among those who think that science has great beauty. A scientist in his laboratory is not only a technician: he is also a child placed before natural phenomena which impress him like a fairy tale. We should not allow it to be believed that all scientific progress can be reduced to mechanisms, machines, gearings, even though such machinery has its own beauty."|
| ||"Nature becomes fertile only by virtue of laws that oblige matter to organize itself into one of a number of necessarily very simple primitive forms. Because of their very simplicity, these are capable of constituting the basis for increasingly complex bodies, by the addition of organs calculated according to identical laws of possibility."|
| ||"There is nothing which Nature so clearly reveals, and upon which science so strongly insists, as the universal reign of law, absolute, universal, invariable law... Not one jot or tittle of the laws of Nature are unfulfilled. I do not believe it is possible to state this fact too strongly... Everything happens according to law, and, since law is the expression of Divine will, everything happens according to Divine will, i.e. is in some sense ordained, decreed."|
