Story of Sir Winston Churchill & Sir Alexander Fleming

Story of Sir Winston Churchill & Sir Alexander Fleming

His name was Fleming, and he was a poor Scottish farmer. One day, while trying to make a living for his family, he heard a cry for help coming from a nearby bog. He dropped his tools and ran to the bog.

There, mired to his waist in black muck, was a terrified boy, screaming and struggling to free himself. Farmer Fleming saved the lad from what could have been a slow and terrifying death.

The next day, a fancy carriage pulled up to the Scotsman’s sparse surroundings. An elegantly dressed nobleman stepped out and introduced himself as the father of the boy Farmer Fleming had saved.’I want to repay you,’ said the nobleman. ‘You saved my son’s life

‘No, I can’t accept payment for what I did,’ the Scottish farmer replied waving off the offer. At that moment, the farmer’s own son came to the door of the family hovel.

‘Is that your son?’ the nobleman asked.
‘Yes,’ the farmer replied proudly.

‘I’ll make you a deal. Let me provide him with the level of education my own son will enjoy If the lad is anything like his father, he’ll no doubt grow to be a man we both will be proud of.’ And that he did.

Farmer Fleming’s son attended the very best schools and in time, graduated from St. Mary’s Hospital Medical School in London, and went on to become known throughout the world as the noted Sir Alexander Fleming, the discoverer of Penicillin.

Years afterward, the same nobleman’s son who was saved from the bog was stricken with pneumonia.

What saved his life this time? Penicillin..

The name of the nobleman? Lord Randolph Churchill .. His son’s name?

Sir Winston Churchill.



Mystical aura of Dec 21,2012

Mayan civilization was one of the most advanced civilizations in terms of knowledge in astronomy. They had evolved simple tools to predict complex astronomical events. The calender they have invented would surprisingly end on Dec 21st, 2012. It marks the end of a 26,000 yeah sun cycle.

Lately my attention has been drawn into an age old debate of life after Dec 21st, 2012.  The debate has got an element of mysticism after a rare book was found in an book exhibition in Greece. The author of the book was none other than Nostradamus. Now famously called as ‘The lost book of Nostradamus”.  The book contains 7 mysterious drawings, each one having a wheel and a ribbon at the top.  Theorist propose how each one of them foretell the future of of the earth being influenced by astronomical events.  At the end of the 7th drawing, the page has an empty wheel with no spokes and a book with empty pages.

But in astronomy Dec 21st, 2012 is an exciting day. It marks a rare event of sun aligning in with the center of the universe. This event happens once in 26,000 years with the last one being around the time of ice age.  This event is called Dark Rift.

Some of the prophecies written by Nostradamus :

Quatrain 1:55
there will be a great shedding of blood
heaven will appear unjust
both on land and sea and in the air
cults, famine, kingdoms, plagues,confusion

Quatrain 2:3
because of heat like that’s of the sun on the sea
the fish around negrepont will be half-cooked
when in rhodes and genoa there is lack of food

Quatrain 5:98
at a latitude of 48 degree at the end of cancer
there is a very great drought
fish in the sea, river and lake boiled hectic
from the fire in the sky

Quatrain 1:65
atop the summit fractures will appear
the lightning will shatter the stones
three without chains bound up around the middle

presage 16
conjoined here, in the sky manifested
it enter
little rain .. the sky and earth dries
undone, death, caught, arrived at a  bad hour



System on Chip

Its being developed in the area as taken by the processors of present times. It can theoretically do the computation of hundreds of processors. It has an element of parallelism in it. Its called as System On Chip.

Gone are the days when  processors were single core or multiple cores based. In the days of high computing requirements, an alternative technology is being developed. Its being developed in the area as taken by the processors of present times. It can theoretically do the computation of  hundreds of processors. It has an element of parallelism in it. Its called as System On Chip.

Each of these SoC’s are made up of 2D mesh network. A module is present at each of the intersections in the mesh. In turn each of these modules consists of a controller which routes the data to be processed . Also modules are the processing unit of the setup. They contain the algorithm of a particular application which is used for analysing the data. Typically a mesh consists of a NxN network of modules.

The data to be processed is initially split up into small bits. They are assigned a module address and using a main buffer, they are  sent across to the network where the modules receive them and analyze .Then they come up with a result. This result is sent across to the main buffer which would reorganize the results. As the number of modules increase, the processing capability of a SoC would also increase.

I’ve been fortunate to have been working on it for past one year where as a team we have been trying to implement it  on an FPGA . Also the designs developed would be tested in next 2 months. With all the efforts we have put in we are hoping for the best 🙂

The Origin of Zero

It first came to be between 400 and 300 B.C. in Babylon, Seife says, before developing in India, wending its way through northern Africa and, in Fibonacci’s hands, crossing into Europe via Italy.

The number zero as we know it arrived in the West circa 1200, most famously delivered by Italian mathematician Fibonacci (aka Leonardo of Pisa), who brought it, along with the rest of the Arabic numerals, back from his travels to north Africa. But the history of zero, both as a concept and a number, stretches far deeper into history—so deep, in fact, that its provenance is difficult to nail down.

“There are at least two discoveries, or inventions, of zero,” says Charles Seife, author of Zero: The Biography of a Dangerous Idea (Viking, 2000). “The one that we got the zero from came from the Fertile Crescent.” It first came to be between 400 and 300 B.C. in Babylon, Seife says, before developing in India, wending its way through northern Africa and, in Fibonacci’s hands, crossing into Europe via Italy.

Initially, zero functioned as a mere placeholder—a way to tell 1 from 10 from 100, to give an example using Arabic numerals. “That’s not a full zero,” Seife says. “A full zero is a number on its own; it’s the average of –1 and 1.”

It began to take shape as a number, rather than a punctuation mark between numbers, in India in the fifth century A.D., says Robert Kaplan, author of The Nothing That Is: A Natural History of Zero (Oxford University Press, 2000). “It isn’t until then, and not even fully then, that zero gets full citizenship in the republic of numbers,” Kaplan says. Some cultures were slow to accept the idea of zero, which for many carried darkly magical connotations.

The second appearance of zero occurred independently in the New World, in Mayan culture, likely in the first few centuries A.D. “That, I suppose, is the most striking example of the zero being devised wholly from scratch,” Kaplan says.

Kaplan pinpoints an even earlier emergence of a placeholder zero, a pair of angled wedges used by the Sumerians to denote an empty number column some 4,000 to 5,000 years ago.

But Seife is not certain that even a placeholder zero was in use so early in history. “I’m not entirely convinced,” he says, “but it just shows it’s not a clear-cut answer.” He notes that the history of zero is too nebulous to clearly identify a lone progenitor. “In all the references I’ve read, there’s always kind of an assumption that zero is already there,” Seife says. “They’re delving into it a little bit and maybe explaining the properties of this number, but they never claim to say, ‘This is a concept that I’m bringing forth.'”

Kaplan’s exploration of zero’s genesis turned up a similarly blurred web of discovery and improvement. “I think there’s no question that one can’t claim it had a single origin,” Kaplan says. “Wherever you’re going to get placeholder notation, it’s inevitable that you’re going to need some way to denote absence of a number.”


Humble INSAT series satellites from ISRO

ISRO built sheds and started recruiting young scientist at IISC Gymkhana who had not yet heard of satellites. Finally he built a team of around 40. They got hold of a second hand ground station from Australia and set up at Sriharikota. He wanted to build a redundant system so his team built another adhoc station by converting one of the ladies rest room into a ground station at Peenya.

Today i was very fortunate to have listened to Prof U.R.Rao talk about the early days of INSAT series satellites in India. He is one the eminent personalities to have shaped Indian satellite program. He had come to Nitte Meenakshi Institute of Technology, Bangalore, India to inaugurate the Clean Room facility and the Integration chamber as part of STUDSAT project.

Then Prof Rao was a faculty at MIT. Ms Gandhi was the PM. He had been to Russia to request them to launch the ‘would be’ satellite by Russian rockets. They had agreed to it by had one condition attached to it. They wanted Indian to manufacture a satellite in less  than 3 years and it would cost Indian Government cool 3 crores. Ms Gandhi gave the approval when she heard it at the first instance through the telephonic conversation she had with Rao. Beginning of the project faced a major hurdle with the death of the father of Indian space science – Dr. Vikram Sarabhai. But after few years it chugged along . Then began the great journey of setting up the labs and building a team.

Initially they had to choose between Hyderabad and Bangalore. But Bangalore had the edge with its history in Science and Technology. So they got hold of some land around Peenya. They built sheds and started recruiting young scientist at IISC Gymkhana who had not yet heard of satellites. Finally he built a team of around 40.  They got hold of a second hand ground station from Australia and set up at Sriharikota. He wanted to build a redundant system so his team built another adhoc station by converting one of the ladies rest room into a ground station at Peenya.

The team managed to build the satellite and the it was launched successfully. They had christened it as Aryabhata as a tribute to the Indian Mathematician who invented Zero. The satellite changed the face of the villages with black and white TV popping up. Buoyed by the socio-economic success, Indian gov went ahead with the rest of the satellites and called it Indian satellites or INSAT .
