So, a year after receiving his doctorate in 1962, he accepted an<br />
invitation to become an assistant professor at the<br />
University of California, Los Angeles. There, he<br />
started teaching information theory and digital<br />
communications. When it came to teaching the<br />
problem of extracting digital signals out of noise,<br />
the standard way of presenting the subject was<br />
“complex and hard to teach,” Viterbi said. so he set about<br />
trying to simplify the concepts “to teach the advanced<br />
course in a better way.” After three months of concen-<br />
trated thought, in March 1966 he figured out a simplified<br />
solution.<br />
Thrilled at having devised a powerful new teaching aid,<br />
he wrote a paper (published in 1967 in IEEE Transactions<br />
on Information Theory) that frst expressed what is now<br />
called the Viterbi algorithm, for teasing a faint digital signal<br />
out of strong noise . But a colleague pointed<br />
out that the algorithm—if it could be implemented in hard-<br />
ware—also had powerful practical application in improving<br />
the actual performance of communication systems. In fact,<br />
it was so powerful that engineers using it for missiles,<br />
spacecraft tracking, or cellular telephones could pick from<br />
a wonderful smorgasbord of choices: reducing transmitter<br />
power, reducing receiving-antenna diameter, extending the<br />
range of a transmitter, operating in a jammed environment,<br />
or increasing the number of users supported in a cellular<br />
system.<br />
And therein lay the fundamental secret of the Viterbi<br />
algorithm’s long, fruitful application in so many industries.<br />

<br />
There are lot of myths attached to 'maths'.<br />
Only some people can be good at math and people need to possess certain kind of mind and mindset to excel in math ...<br />
<br />
One of the profound idea that I came across in the following series of lectures of 15 to 20 minutes is that by making mistakes while doing math, two additional neural connections are formed.<br />
1. While making the conceptual mistake<br />
2. While reflecting and correcting the mistake<br />
<br />
It continues to argue that people who get it right first all the time tend to have Fixed Minds whereas the the people tend to make more mistakes have a Growing Mind due to the increased neural connections !!!<br />
<br />
