No doubt, art starts with a drawing. Often science too starts with a drawing! A drawing is, in fact, a bridge between Art and Science. Learning to draw well puts students of science and Maths on a firm pursuit of learning (I speak from personal experience). I have not seen another teacher who can draw a perfect circle before a class on a black (white)-board, instantly, like my Math school-teacher did back in the day. He taught us fourteen theorems of trigonometry in final-year of our school, with elan. He always started the class by drawing a perfect circle on blackboard, effortlessly in one shot, without lifting the chalk piece. The level of his confidence in doing so inspired the students to learn not only the subject of trigonometry but also to draw!

Some Art teachers become an inspiration for young students to take up painting. Some have a penchant for making colored-pencil drawings of famous monuments of our metropolis - old Gothic buildings, driveways, and other inspiring architectures. He recently held a full-fledged exhibition of all his paintings in an art gallery. Dr. Homi J. Bhabha, the architect of Indian nuclear energy program, was an accomplished artist too, who drew pencil drawings (portraits) of several celebrities, among them two famous Nobel laureates - Sir C.V. Raman and Prof. P.M.S. Blackett. The layout of the beautiful gardens maintained at the Tata Institute of Fundamental Research and at Bhabha Atomic Research Centre, both in Mumbai were all planned by Bhabha after sketching them at his drawing board. The famous painting Starry Night (1889) by van Gogh drew inspiration from the depiction of a spiralling whirlpool galaxy by the astronomer, W. Parsons in 1845. Neuroscientists are giving profound meanings to what goes on in our minds when we look at drawings/paintings made by celebrated masters, such as the Woman in Gold, a portrait of Adele Bloch-Bauer I, by Klimt in 1907. Eric Kandel, the 2000 Nobel Laureate, proposed that as we walk and forth in front of this painting, the eyes of Adele seem to follow us because our visual systems convert a 2D image into a 3D portrait in our minds. Though the picture that forms in our visual and cerebral cortex, when we look at a sketch or a painting, is same for all individuals, the way it is processed, analyzed, resolved visually and emotionally, and reconstructed in our brains based on our past experiences and lifestyles, makes each person see a different view. In fact, the boost that each one of us gets in the number of synaptic contacts between our nerve cells is specific to the individual, and that alone decides the capacity of an individual to think and feel about what he/she makes out of the sketch/paintings. That also largely explains why different onlookers make out the extent of the hidden smile of 'Mona Lisa' to different levels when they are looking at it in The Louvre Museum in Paris. Similarly, it is up to the onlooker to decide whether it is a human figure shrieking or an inverted Edison's bulb in The Scream, the 1893 painting by Edvard Munch. ( )
