Research and Development

The man having three world records in the field of memory realized the problems being faced by students in the conventional education system, with the vision to shape the way of coming generation he took an initiative to enable students to permanently store the information in their mind. While teaching the students, he realized that everyone is using the method of memorization incorrectly, most of the students are cramming rather than memorizing permanently, Due to which they forget the information after some time. Once a parent asked Sababbi Mangal that his son sits for hours with a book to memorise, but is not able to recall any information later. After investigation, they found that he repeats the information to memorise, that’s why he forgets every time. Thinking seriously on this matter, he found that the conventional way of education is not of the desired standard, he then started working on new research – how the brain works? why we forget? what is the scientific way to memorize information permanently? With this task at hand Dr. Sababbi Mangal started research in the field of memory, concentration, focus, Vedic -mathematics and neuroscience and invented several techniques to enhance, sharpen, boost and simplify the education field. He resolved that he will also change the method of education and skill training being imparted, apart from the entrepreneurship development programs providing equal opportunities to all.

He established Asia’s First Neuroscience and Meta Skills Research Centre at Solan, Himachal Pradesh for the training of teachers to improve the quality of education. It was inaugurated by the Education Minister, Government of Himachal Pradesh.
