Inheriting the mantle of revolutionary biologist from Darwin, Watson, and Crick, Richard Dawkins forced an enormous change in the way we see ourselves and the world with the publication of The Selfish Gene. Suppose, instead of thinking about organisms using genes to reproduce themselves, as we had since Mendel's work was rediscovered, we turn it around and imagine that "our" genes build and maintain us in order to make more genes. That simple reversal seems to answer many puzzlers which had stumped scientists for years, and we haven't thought of evolution in the same way since.
Why are there miles and miles of "unused" DNA within each of our bodies? Why should a bee give up its own chance to reproduce to help raise her sisters and brothers? With a prophet's clarity, Dawkins told us the answers from the perspective of molecules competing for limited space and resources to produce more of their own kind. Drawing fascinating examples from every field of biology.
Personal Narrative of Travels to the Equinoctial Regions of America, during the years 1799-1804 is a three-volume account of an expedition taken from Spain to South America by naturalists Alexander von Humboldt and Aimé Bonpland. The authors visited Venezuela, Cuba, Andes, Mexico and USA where they collected the material and made extensive notes. Their joint effort to record a memoir of this great expedition is quite interesting and valuable because it contain specific documentation of their scientific observations, but it also presents an intriguing and romantic work with many poetic descriptions of nature and the people who lived in the areas he visited.
Basic quantum chemistry provides a coherent and structured approach in introducing the concept of 'quantum' to the students of quantum mechanics. An attempt is made to bring out the subtleties of quantum mechanics, hidden in its abstract laws and equations, applicable to the atomic domain by showing its relevance to the observable macroscopic world as well. This is nothing but providing “QUANTUM INSIGHT” into the nature of reality to enable one to think about the universe in a different perspective. The book helps the reader to dispel the stigma associated with quantum mechanics. The emphasis on conceptual approach provides a platform to stand on, and a stimulus to pursue higher quantum mechanics, the doorway to the all-pervasive quantum world.
