Shortly after its inauguration in 1985 the Birla technology Centre, Hyderabad, India, all started a chain of lectures through Nobel Laureates and different scientists of foreign renown, often in Physics and Astronomy, occasionally in existence Sciences and Chemistry.

The current assortment in most cases includes lectures on frontier subject matters. The transcript of every lecture is preceded through a quick biography of the Nobel Laureate/Scientist in question.

The lectures are geared toward, and obtainable to a large non-specialist yet greater proficient audience.

Winner of the 2005 Pfizer Prize from the heritage of technological know-how Society. What truly came about within the inner most laboratory of a mid-seventeenth century alchemist? How did he direct his quest after the secrets and techniques of Nature? What tools and theoretical ideas did he hire? utilizing, as their advisor, the formerly misunderstood interactions among Robert Boyle, widely recognized as "the father of chemistry," and George Starkey, an alchemist and the main favorite American medical author ahead of Benjamin Franklin as their consultant, Newman and Principe display the hitherto hidden laboratory operations of a recognized alchemist and argue that a few of the ideas and practices attribute of contemporary chemistry derive from alchemy.

This is often the 'current definitive' variation of Darwin's theoretical notebooks, and it's more likely to stay so for a time.
The 1987 1st version used to be re-rendered digitally in 2008. in this model relies the ANMH on-line variation from which the vast majority of this P2P reconstruction originates. See 'comments' for details.

From the publisher:
Darwin's notebooks offer a useful list of his medical pondering and most significantly, the improvement of his conception of typical choice. This version of the notebooks, ready to the top normal of textual modifying, therefore provides a unified view of Darwin's expert pursuits. The pink laptop, used at the voyage of H. M. S. Beagle and afterwards in England, includes Darwin's first evolutionary statements. In July of 1837, Darwin begun his 'Transmutation Notebooks' (B - E) dedicated to the answer of the species challenge and within the 3rd computing device of this sequence he first formulated the idea of common choice.

Example text

As Dr. Sidharth has pointed out, my predecessors in this lecture series have been a very distinguished four and I shall find it very difficult to follow them. But it is noticeable that they have all been in rather elated fields of astronomy and mathematical physics and so I am the first one who is not in the category, well I don’t know what I really am. I started as a chemist and now am in a Biological department and so I am on the Chemical Biological side of science and so I hope this is some justification for my being here and balancing the science as I hope Mr.

This may be an advantage up to a point: the beam size will shrink because of the mutual attraction and this will increase the luminosity. However, above a certain limit, this “disruption” effect becomes so strong that the beams will be over focussed and spread out again before they have had much chance of interacting. Moreover, in being so deflected by each other, the particles will again radiate energy. This effect (called “bremstrahlung”) turns out to be so strong that the beams may loose too much energy during their interaction.

In recent history things have changed enormously. Look what’s happened in the last one hundred and fifty years. A hundred and fifty years ago, the energy the world used was 90% wood. It was much more than that in countries like India but it was 90% wood in most of the developed countries. And in fifty years that had changed so that 70–80% was coal. Finally a hundred years ago or so, coal began to be replaced by oil and gas which now dominate – from around 1970 the process has gone a little further and coal is rapidly becoming less and less popular.
