Indian Space Research Organisation has built a supercomputer, which is to be India's fastest supercomputer in terms of theoretical peak performance of 220 TeraFLOPS (220 Trillion Floating Point Operations per second). The supercomputing facility named as Satish Dhawan Supercomputing Facility is located at Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram. The new Graphic Processing Unit (GPU) based supercomputer named "SAGA-220"  (Supercomputer for Aerospace with GPU Architecture-220 TeraFLOPS) is being used by space scientists for solving complex aerospace problems. The supercomputer SAGA-220 was inaugurated by Dr K Radhakrishnan, Chairman, ISRO today at VSSC...  

This month is the centenary of what is arguably the most amazing discovery of the 20th century – that the apparently solid world around us is mainly empty space.  Yes atoms the basic structural units of the entire universe are more than 99.9999% empty. (But empty space have quiet different meanings - quantum mechanics never speak of empty space). Imagine how it will be when there is no empty space in an atom - the unverse would shrink to 0.00000001 % (u can put 12 zeros between '.' and '1' ).

In May 1911 Philosophical Magazine published a research paper by Ernest Rutherford. He had analysed the results of some measurements by Hans Geiger and Ernest Marsden, who worked with him at Manchester University. The analysis led Rutherford to the conclusion that all the positive electric charge within an atom, and most of the mass, must reside in a tiny central region, with the negatively charged electrons swirling round far away. The central core became known as the atomic nucleus and the study of it led to our understanding of the fundamental particles and forces in the Universe.
