Thomas Bata the owner of the global show corporation died in Toronto early on 2nd of September at Sunny brook Hospital, he was 93 years old. Bata is survived by his wife Sonja, a son and three daughters. Thomas Bata's father started his shoe empire in 1984 at Zlin which later had a global presence; it continues to be a household name in India.

Review of IBM Super Computer
Guys I came across an article about IBM's New venture and hope it will help you to know about new technology. IBM researchers from the T.J. Watson Research Center reached a significant milestone in the quest to send information between the "brains" on a chip using pulses of light through silicon instead of electrical signals on copper wires. The breakthrough -- a significant advancement in the field of "Silicon Nano photonics" -- uses pulses of light rather than electrical wires to transmit information between different processors on a single chip, significantly reducing cost, energy and heat while increasing communications bandwidth between the cores more than a hundred times over wired chips.
The new technology aims to enable a power-efficient method to connect hundreds or thousands of cores together on a tiny chip by eliminating the wires required to connect them. Using light instead of wires to send information between the cores can be as much as 100 times faster and use 10 times less power than wires, potentially allowing hundreds of cores to be connected together on a single chip, transforming today's large supercomputers into tomorrow's tiny chips while consuming significantly less power.
IBM's optical modulator performs the function of converting a digital electrical signal carried on a wire, into a series of light pulses, carried on a silicon Nano photonic waveguide.
First, an input laser beam (marked by red color) is delivered to the optical modulator. The optical modulator (black box with IBM logo) is basically a very fast "shutter" which controls whether the input laser is blocked or transmitted to the output waveguide.
When a digital electrical pulse (a "1" bit marked by yellow) arrives from the left at the modulator, a short pulse of light is allowed to pass through at the optical output on the right.
When there is no electrical pulse at the modulator (a "0" bit), the modulator blocks light from passing through at the optical output.
In this way, the device "modulates" the intensity of the input laser beam.

Are we Unique?
As of now EVEN with our limited knowledge we can assure that there are (were) no two human beings alike. For that matter existence of two similar objects (any objects even in their lowest form of existence) itself is a highly improbable possibility. Of course, I am talking on gene to gene and atom to atom basis. My point is if there are this many of constraints in forming two similar objects with the limited combinations why we can’t expect that WE ARE UNIQUE. Let u be the creator and just compare the combinations (of ???) you have for the manufacture of a human body with that of a planet like ours(hey just consider the physical aspects, otherwise you'll end up in messing all kinds of things, and that’s altogether a different science). So just imagine how improbable it is to have two sets of similar conditions which caused to the rise of life in its present form. Finally my point is simple. "As long as u don’t expect the one very similar to you (again on gene to gene and atom to atom basis) in your very next door it is reasonable enough to believe that WE ARE 'THE' LUCKIEST ONES ON OUR OWN AND THE, OTHERWISE, LONE UNIVERSE (pack the string theory for the time being).

Learn about Gravitation Lens
It is from Einstein's equivalence relation (General theory of relativity).
According to it, Space time is curved around an object having mass The greater the mass, greater the curvature. If you see through such a curved space-time, image seems Stretched to you around the corners of the object this is gravitational lensing(also known as optical effect of gravitation)
