Learning Mathematics a not so easy job -Whats the science dude?

Ramesh had got his result from school today .His summer vacations had just got over and the school had for some odd reasons a rule to announce their final results after the summer vacations .Ramesh had fun during his vacations and had promised his mother that he will study when the school starts.
Geeta ,Ramesh’s mother was very particular about his academics and was always in touch with his school teachers about his academic progress. She knew Ramesh was weak in mathematics and he did like the subject. He would run away whenever she tried to teach him maths.Probably the reason was that he spends most of his time reading story books or painting.Anyways she got him last year a professional math’s private tutor who would sit with him every day for one hour. She was sure there would be improvement in his scores.Ramesh disliked the teacher for obvious reasons. When Ramesh showed Geeta his marks she could not believe her eyes .His scores had only marginally improved from  50 , he had improved to 55.But surprisingly his English and Art marks had improved almost 20 percent as compared to last year.Geeta was perplexed how this had happened even after putting so much effort .

So let me try to explain how our brain works when we do maths.Mostly everyone knows that the term "dyslexia" refers to people who can't keep words and letters straight. A rarer term is "dyscalculia," which describes someone who is virtually unable to deal with numbers, much less do complicated math. Scientists now have discovered the area of the brain linked to dyscalculia, demonstrating that there is a specific part of the brain essential for counting properly.

The idea that mathematical skills reside only on the left part of the brain proved to be a myth. In reality, in most activities, the entire brain is used at all times. Mathematical thinking entails complex brain functions, interconnected to perform even the simplest of functions. For example, you may use the right parietal lobe to get close to a mathematical solution; however, to get the right answer, the left hemisphere further processes your solution

The right hemisphere matures before the left hemisphere for most cognitive skills, such as numerical understanding or appreciating quantities.
 According to scientists, both types of numerical knowledge employ parts of both the parietal and prefrontal cortex in adults.


Creative mathematical ability involves discovering multiple solutions to a problem or solving real world problems. Scientists affirm that highly gifted creative mathematical thinkers employ extensively the parietal and frontal areas on both parts of the brain. Studies on Einstein’s brain proved that regions of his right parietal area were so dense with neurons that one of the major cortical indentations (IPS) was actually filled in completely and difficult to locate . The intraparietal sulcus (IPS) region is activated when a person thinks of numbers or does math. The inferior frontal gyrus known as Broca’s language area, is responsible for expressive language, such as speaking or writing.
 Another area, known as Wernicke’s language area is responsible for understanding spoken or written language. Recent studies have shown that Broca’s plays a large part in understanding syntax in addition to forming it.
All of these areas appear in the dominant hemisphere (side) of the brain, which in 97% of the population is the left side.
Geometry is associated with visual-spatial representations – analysis of space, shape, points, lines, angles, surfaces, and configuration, etc, which are activated in the right cerebral hemisphere - the right parietal and frontal areas of the brain, to be more specific. 
You would need the synchronization of eight separate parts of the brain for the different arithmetic operations. 
For example, for identifying written digits, you activate the left and right visual cortices. 
For understanding quantities – the left and right parietal cortices . 
To solve word problems – the left temporal cortex and
 for complex mathematical reasoning – the left and right frontal areas.


Imagine how you really pick the shortest checkout line.You could count the number of shoppers in each line, in which case you'd be thinking discretely in terms of numerosity.
But if you're a hurried shopper, you probably take a quick glance at each line and pick the one that seems the shortest. In this case you're thinking in terms of continuous quantity. The two modes of thinking are so similar but the difference lies in the way your brain executes the function. For kids who find it difficult learning math’s the first method is a better option. Rather than hurrying into answering the mathematical problem Understanding,analysing and then calculating seems to be more prudent solution .
As for Geeta she accepted the fact that her child was able to paint and read much better than arithmetic problems and she stopped pressurizing Ramesh for mathematics rather encouraged him to take his own time and solve the maths problem to the best of his abilities.

Law of attraction a myth or reality- Whats the science dude?

It was a wet Sunday Morning and Rahul had decided  to take a total break from work. He was due for this as he had just finished his project for which he had toiled his heart  and soul by working day and night since the last one month. He had planned for a long drive with his beautiful wife and daughter to Lonavala Ghats (a small hill station close to Mumbai, India). He got up by the clattering sound of the rain falling on his roof which instantly gave him a smile. He realized that it was going to be a beautiful weather and things were magically working out exactly the way he had planned. He woke everyone up and much to his surprise, within half an hour everyone was in the car on the way to a beautiful day ahead. They were in such high spirits that they started singing songs and cracking jokes. As they started reaching closer to their destination, there was huge traffic on the Ghat which was moving at a snails pace. There was constant honking by the fellow travelers which was irritating Rahul.  It was almost an hour and Rahul started getting annoyed, blaming the government, people,cars and police for this mismanagement .Suddenly the mood became tense in the car and the couple almost decided that they will turn back rather than wasting their Sunday in traffic. Except his 7 year old daughter who was listening to music all the while the couple was really getting annoyed. 

Then a young girl Babita aged 19 who was selling toys on the road came up to them and told them that they were lucky as this traffic was there since last night and only now had started moving. God had blessed their family with grace and kindness unlike her who was an orphan and  she did not have a family. Still she was happy as hot summers had finally got over and she did not like hot weather .She wished good luck for them and requested them to buy some soft toy as a memoir of this beautiful day they plan to spend together. Rahul who normally shooed of these road side sellers, suddenly felt overwhelmed with happiness and an urge to buy a soft toy as remembrance to this beautiful moment. He looked at the girl who was dressed in dirty Salwar Kamiz(dress worn by Indian girls) but her face was markedly filled with happiness which was infectious. He bought 3 soft toys from her ,one for each of them and shared some food packets they had bought along.Suddenly all the irritation and anger which had accumulated in him disappeared and they had a great day in spite of  getting stuck in traffic one hour post their encounter with the girl.

The law of attraction is the attractive, magnetic power of the Universe that draws similar energies together. It manifests through the power of creation, everywhere and in many ways. Even the law of gravity is part of the law of attraction. This law attracts thoughts, ideas, people, situations and circumstances. The happiness ,the little girl exhibited had an effect on  Rahul’s brain pathway which rewired the negative thoughts ‘the dominant the traffic snarl’ to positive thoughts.Suddenly from a happy mood in the morning to anger and irritation due to traffic and then back to happiness, the long journey is an essential part of everyone’s life. We can all co relate this to some incident in our life .Why this happens and what are the changes which take place in our highly complex brain can be explained with the recent development in Neuroscience, Neuroplasticity and Neurophysics .
Ralph Trine wrote in In Tune With The Infinite (1897):
"The law of attraction works universally on every plane of action, and we attract whatever we desire or expect. If we desire one thing and expect another, we become like houses divided against themselves, which are quickly brought to desolation. Determine resolutely to expect only what you desire, then you will attract only what you wish for". 
To simplify it ,I will try to explain first  the anatomical structure and functioning of the brain. The brain can be divided for the sake of understanding into its  physical structure,neurochemicals and  electrical impulses. I will try to briefly explain which part gets activated in  the above incident and then why it happened so.

All of us agree these high paced emotional turmoils are a common phenomenon in most of the  lives of people .The part of the brain responsible for firing of emotions is an almond shaped structure called amygdala which develops from two years of birth and is responsible for firing of the emotions .Another brain structure of importance in this scenario is the Nucleus Accumbens which is also known as the reward center and is the one responsible for feeling happy by activating the reward circuit. This was the center which was activated what  Rahul experienced in the morning and when Babita spoke to him. The Nucleus Accumbens is the one responsible for secreting dopamine which is the neurochemical responsible for happiness(positivity) and activates the reward circuit. 
Similarly when the amygdala gets fired when Rahul was angry .The brain releases the GABA  (gamma amino butyric acid) and serotonin which is a inhibitory neurochemical responsible for negative emotions. It gives us a negative aspect of the situation  and too much of GABA and reduced levels of serotonin  leads to depression.This forms the basis of pharmacological treatment of depresion.
The way our brain has been conditioned due to the genetic predisposition of our ancestors has resulted it in been naturally bias to negative inputs .However a word of caution ,these were necessary for survival. For example when we are walking in a dark forest and we come across some long twigs, this negative bias is responsible for our mind to think that there may be a snake which protects us from the coming danger. But the same pathway also gets active when we are stuck in traffic what we call in today's world as stress. Also these messages are quickly send along the neurons (wires in the brain through the synapses(gaps between neurons where a neurochemical is released. These impulses create an image in our mind which is our perception depending upon on what we believe on the given situation formed by these neurochemicals.

So coming to the law of attraction where like poles attract and opposite  repel. One explanation is given by discovery of Mirror neurons. Mirror neurons are created by an individual  by replicating the same circuit which is present in the opposite person as perceived by our special senses (eyes,ears,skin,smell) .What Rahul got irritated by constant honking or his wife got irritated by creating these mirror neurons  on seeing Rahul's irritation are examples how mirror neurons are formed. These can be explained when huge rallies by political speaker suddely lead to violence by inflammatory speeches used by them .The mechanism responsible is that the brain creates images in our mind  and these  are replicated in the opposite persons mind. The only thing to ponder is the speed with which the mind can create these mirror images.

The other explanation is given by the quantum theory of physics about electromagnetic effect of individual atom. Similarly, since each cell is made of atom having positive and negative charge they have a  field of electron around them .When driven by powerful emotions(highly charged emotions)  these circuits create the same or opposing  alignment in opposite person’s circuit which creates  a  response. Hence,Emotions are infectious and being positive  and having an optimist approach to lives are some of the solutions  given by elders and renowned psychologists  to the caretakers when dealing with a case of depression.

Another factor responsible is the part of the brain called OrbitoFrontal prefrontal  Cortex (OFC)l lobe also known as the social brain. Humans right from birth have a craving for social interactions starting from the smile and cuddling by the mother. Every human being craves for this basic need like food,water and shelter and is often under estimated as we become adults. In our desires to achieve success and pursuit for our goals we tend to overlook this basic need. Children who have a disturbed childhood tend to be emotionally disturbed as compared to the other kids. Although they have a desire for more affectionate relationships, the poor social skills learnt because of a disturbed childhood tends to create unstable relationships. Such kids create these mirror neurons right from the early age and are very difficult to overcome in adulthood.These are learned at a very tender age and form the basis of relationship in adulthood.
The world is moving today from what was a technological revolution to  an over driven and highly overworked socio emotional complex circuits in our brain. The basic understanding of the laws of attraction is the first step towards untangling  the complex and jumbled up brain pathways which is  leading to an  impulsive and over reactive society.
