Ode to all pointless….

In the distant past and space a supernova exploded for apparently no reason, sending two photons off the wombs of couple of intimate atoms – The radiant twins were born so. They joined waves of new born corpuscles rushing out to enlighten the universe.
But, as fate would have it, a small ripple in space-time pushed them in different directions – not quite as emotional as twins lost in the cosmic mela, but would have to work for this story.
First photon, you can call him Ram if you want, travelled to the heartlands of India, reflected off a malt of wheat and smashed into the retina of a monkey sucking a mango. Disregarding the destiny of our dear photon who travelled vast space-times, the callous specimen of monkeys, continued sucking the mango… A millennia of photonic life time wasted.
Meanwhile, the entangled twin, you can call him Shyam, if you are a Bollywood freak, raced at a flowering monkey and deflected on to the EM sensor of a lazy corn, idling under the shadow of an Indian elephant, sucking a fruiting bat. Corn didn’t give a damn to the tired traveler and continued its avocation

He just watched it all and rolled another dice of the quantum game.

Why do we like music? An amateur's analysis


Have been listening to a melodious Malayalam song..So captivating...but so is the Korean song - Gangnam style...
Music is beyond languages..It is purely about rhythm...or should I say "Symmetry"?
Why is that humans like music? Let’s take that question - probably many other living things are attracted to music. Stories abound how plants grow better listening to music etc...But let’s try to understand a simpler question...
Why human do’s like music?
I happened to listen to a documentary on people with autistic disorders, but having special abilities in
Math’s or music or art...Couple of these savants were very interesting... There is one savant who is able to do big mathematical calculations by not even performing them consciously...He sees shapes and colors for numbers which eventually merge into a different shape which is the answer to his calculation
The word amazing...doesn’t even qualify to describe this
There is another Savant who is able to play any piano based music he had listened once and there is another blind and mute savant who started playing piano overnight. There are also many savants with amazing photographic memories...
Why is it that shapes, music and math’s come so naturally to us...In many cases it seems like the desire or ability for math’s or music or art is inbuilt into our brains..
There is another savant story- albeit from an article, not from the BBC documentary, about a pair of savant twins. They communicate in numbers and eventually it was noticed that all of those numbers were primes
All these beg the question? Why is that the interest or ability or appreciating for music/math’s/painting built into our system?
Everything any living being does, is eventually a handiwork of evolution.
One thing common in music or math’s or art is the inherent symmetry...in some cases obvious or in some other cases a little less so
So, we seem to be interested to symmetry...But why so?
Probably because we are symmetric!
Almost all the species seem to have left- right symmetry
I read about this in an article...as to why there is left -right symmetry
To understand this, first we have to understand the rationale of asymmetric design in us.

Our top and bottom are asymmetric. For any reasonably fast moving land animal this is the case. Because we need our foot to help us in locomotion and also help us to stand against gravity
So, this asymmetry is an output of gravity and need for movement - i.e., physics and food...two things I enjoy
We also have front to back asymmetry..This is the case of any relatively fast moving animals. We need one end to see predators or preys or to look out for mates (Probably some humans would have wanted eyes at the back also for this :) ). Anyway evolution gave us eyes at the front only,  for this purpose, probably taking into consideration the cost and processing power required in maintaining an eye .So, a tree with no eyes and no means to run,ended up with just the top to bottom symmetry
Now..It leaves us with just one kind of symmetry...left -right...And here, ho, we are symmetric ( at least externally). So are, seems most of the living beings...
Why is this so?
This could be to save the extra coding required in our DNA for building any left-right symmetry. We don’t seem to require any left -right symmetry as there no strong horizontal forces in our planet. Our magnetic forces are very weak to have influences any left-right asymmetry.So, we are left - right symmetric..and hey, this symmetry is beautiful
Many studies have indicated that more symmetric people are thought to be more attractive..Not just by grown up people, who could have been prejudiced by social and other considerations, but by even small babies. Babies tend to look at symmetric babes!
So, love for symmetry is into us...again why is this?
Because - in the end all our likes and dislikes are tuned by a million years of evolution just to pass our genes. That’s the whole purpose of any living being...just survive enough to pass your genes...Raw but the ultimate truth
So, more symmetric implies, a better coded DNA...Better DNA has a better survival chance and hence we love it! So, our love for symmetry is - shall I say an intelligent design of the evolution :)
Hence love and processing ability of symmetry is inbuilt into the brain...
This might explain why we have so much of natural appreciability of math’s or music or shapes..
Not a very convincing line of thought :)

Gold bach Reloaded

Inferences from Strong Gold Bach’s Conjecture

Strong Gold Bach’s Conjecture is as given below:
e  even number
p  prime number
o  odd number
According to Strong Gold Bach Conjecture,
Any even number >=8 can be written as a sum of two different primes.

Now let’s get into my observations...
Using Strong Gold Bach’s conjecture
Any e = p1+p2, where p1 and p2 are two different prime numbers

Now take any prime number p
2p is an even number,
So 2p = p1 + p2 using Strong Goldbach’s conjecture where p1 and p2 are two different primes

So,

p = (p1+p2)/2

Inference1:

Therefore any prime number can be written as the average of two different primes.

E.g.:
Take 17
2*17 = 34 = 31+3
Therefore 17 = (31+3)/2
This also means that any prime number is equidistant from two some other two primes
This inference shows the uniformity of the primes though they can’t be represented by a single formula

Inference2:

Since p = (p1+p2)/2, using the above inference,
p1 can be a maximum of 2p-1 so that the other prime can be a minimum of 1

From this we can see that if p is any prime, there is at least one prime number between p and 2p

E.g.:
Take p =
31 and 2*31 = 62
Between 31, there are primes 37, 43 etc...

Inference3:

According to Strong Goldbach’s conjecture, any even number
e = p1 + p2, where p1 and p2 are two different prime numbers
But,
e = o1 + o2, where o1 and o2 are two non prime odd numbers
So basically, o1 + o2 = p1 + p2
Hence, suppose o1 = p1 + x, where x is some difference
Then o2 =p2 –x, since, in the end the (p1+x) + (p2-x) = p1+p2 = o1+o2
Hence we can see that
For any two pair of odd numbers, o1 and o2, you have two prime numbers p1 and p2, such that
p1Similarly, there is another group, o1
So, any pair of odd numbers has a pair of symmetrically placed primes

E.g.: Take two odd numbers, say 15 and 57. Here the primes below 15 are 3, 5, 7, 11 and 13. So I just take the differences of this number with 15 and add those to 57, one of them will be definitely a prime.
So 57 + (15-3) = 69  not prime, 57 + (15 – 5) = 67  Prime! So the numbers are 5, 15, 57 and 67

Inference4:

There are two primes equidistant from any number!!

According to Strong Goldbach’s conjecture, any even number
e = p1 + p2, where p1 and p2 are two different prime numbers.
So p1 = e/2 –k and p2 =e/2 + k

Hence we can see that this points to the fact that there are two primes equidistant from any number ,as the e/2 can be an odd or even

Eg: Taking a76, we have 73 and 79. Taking 109, we have 79 and 139 and equidistant primes from 109

This is useful if we know all primes lesser than a number N and then we just have to check if the numbers N+(N-pi) are primes, where pis are primes below N

Energy sources

Was just wondering if there are any renewable energy sources not being used effectively...We all know that solar, wind, tidal energy etc are being used to various extents...Sitting at the MCity FC during lunch time, there is a seemingly endless buzzz..100s of people talking, laughing etc...their sound waves being added to produce a sound like the one you get at theh beach...So what if we could convert this to energy?
Use a microphone...convert these sounds to electric signal...rectify that to get dc and use it to charge ur battery...
Might be this dc will be of very low value...but what ever you get free is good :)
Did some research on net regarding this...seems that people are thinking and researching about this....
Noise is one thing which is there all around us..Hopefully someone will change the proverb "Silence is golden" :)

Direct brain communication

This is an offshoot from the previous blog entry

Direct brain communications is something like sending ur brain signals or thoughts directly to someone else...
This will be great...like a movie director having an idea and then communicating that image/video to his actor or the camera man using brain signal...

Probably this can be implemented by having a transmitter and receiver attached to our brain or head ( strong enough to interact with brain )
and then sending this signal to anly place using the normal mobile/ satellite network...

This will be like any normal mobile...We should be able to take only the brain calls we want :)...

Probably we could go to the next level and allow some users to access ur brain thoughts all the time ..without u having to send that implicitly Guess this will be ultimate telepathy...

But this might affect privacy a lot...so privacy settings also might have to be implemented :)

Also probably you could use this equipment in record mode to record ur dreams :) might be useful as people are supposed to have bright ideas in dreams

Interesting idea

When in school i had had an idea of transferring smell from one place to another...The idea was use the smell molecules to drive a turbine to get an electric signalwhich can be transmitted to another place where it can be used to turn another fan to get back the smell !! Bad that i didnt apply for a patent :)

Recently when discussing with my frnd Akash, he told that it would be really nice if we could transfer smell over internet. Eg : If u are planning to buy a perfume, it wouldbe great to smell it before buying rather than falling for the pic of the perfume bottle of the lady advertising it. Obviously transferring smell has its disadvantages/ dangers also ... Imagine some one sending u an attachment with H2S smell :) or worse some terrorist sending a mass mail with poisonous gas

Anyway, looking at the bright side, lets see various options of implementing this:

1)One way would be to send the molecular structure of the smell from the server to the client and the client system having a smell synthesizer using this info to generate the smell molecules. I guess this idea is too far fetched or impractical
2)Another way would be to trigger smell sensation using some other sensations like sound or sight. Not very sure if this is possible. The reason i thought this is possible because most of the senses are kind of overlapping..eg..when u eat apple when having nose block...u dont get the full taste..
So if this is possible, the client user can use an earphone and when he clicks a perfume icon, a sound/image or a combo will be generated which will give him the smell sensation
3)The other way seems to be most possible way. It is to send electrical signals directly to brain ie, the user will have a head cap which will receive electric signals from the server side...These signals will create the necessary smell sensation...Like u get smells in dream without the molecules being present.

The last idea, ie, directly communicating with brain is being researched by scientists..Guess it has lot of possibilities...

You could even transmit touch and other sensations though internet...This might lead some one to strangle you through net :) We might get e-murder cases...Also the horror movie experiences will get much better...

Now the brain communication is such an interesting idea..that it deserves a look in another blog entry

Global warming.....

I attended a session on global warming today...
It had the usual suggestions to reduce CO2 emissions etc...
Being an engineer , i am more interested in quick fixes...
Some suggestions below...

1)White snow and ice reflect most the energy from the sun while dark oceans and land absorbs this energy. This is one reason why the melting ice caps accelerate the global warming...
So one solution is to coat all our outer roofs with materials of similar reflective properties of ice...so that a huge amount of sunlight is reflected back to atmosphere.... :)...So coat every house terrace, all vehicles etc with this material
The idea is simple...create more ice caps :)


Will try to come up with more :)
