Bedtime Story  


Concluding Remarks of the Paper: ‘The Human Brain in Numbers: A Linearly Scaled-up Primate Brain’ - Part 2 and Note A of Ada Lovelace Part 1


Tonight we shall finish with the concluding remarks of the paper ‘The Human Brain in Numbers: A Linearly Scaled-up Primate Brain’ published in the journal Frontiers in Human neuroscience in 2009.   

“Finally, if being considered the bearer of linearly scaled-up primate brain does not sound worthy enough for the animal that considers himself (note the author being a female has used a male adjective) the most cognitively able on earth, one can note that there are, indeed, two advantages to the human brain when compared to others – even if it is not an outlier, nor unique in any remarkable way.

First, the human brain scales as a primate brain: this economical property of scaling alone, compared to rodents, assures that the human brain has many more neurons than would fit into a rodent brain of similar size, and possibly into any other similarly-sized brain.

And second, out standing among primates as the proud owner of the largest living brain assures that, at least among the primates, we enjoy the largest number of neurons from which to derive cognition and behavior as a whole.

It will now be interesting to determine whether humans, indeed, have the largest number of neurons among mammals as a whole.”

Beautiful ending to a remarkable paper, is it not Mon ami?                     
I would love to go on into comparative and evolutionary neuroscience since it is either from this field or from computer science or both in ideal tandem that we shall finally get the answer to the most elusive problem whose answer till date eludes us – “The origins of the Delusion of I or the self and thereby consciousness”.    

Now we shall return to the Note A of Ada Lovelace after a significant but worthwhile digression for after all we are already witnessing the merger of these two sciences – neuroscience and artificial intelligence.
     
In this Note she starts with the Difference Engine and then goes on to elaborate and justify how fundamentally the Analytical Engine is different from its predecessor – essentially in its universality.   

“Note A

The particular function whose integral the Difference Engine was constructed to tabulate, is

                           \Delta^7u_x=0        

(This is essentially a polynomial function of seventh power which would be expressed in modern mathematical notation the following way:

f(x) = ax7 + bx6 + cx5 + dx4 + ex3 + gx2 + hx + i)

The purpose which that engine has been specially intended and adapted to fulfill is the computation of astronomical and nautical tables.

The integral of

                                                \Delta^7u_x=0

Being

uz = a + bx + cx2 + dx3 + ex4 + fx5 + gx6 ,

The constants a, b, c etc. are represented on the seven columns of the discs, of which the engine consists.”

Good night mon ami and my fellow cousin ape.

Another great educator and a teacher that I am aware of is Professor Subhashish Chattopadhyay in Bangalore, India.

While I narrate stories, Professor Subhashish an electronic engineer and a former professor at BARC, does and teaches real mathematics and physics.

He started the participation of Indian students at the International Physics Olympiad.

Do visit him here:


All his books can be downloaded for free through this link:


For edutainment and English education of your children, I recommend this large collection of Halloween Songs for Kids:
