The branch of Physics which deals with the study of light and various phenomena associated with it is called Optics. In Geometrical Optics (or Ray Optics) we assume that light travels in a straight line in the form of rays. This model is useful for studying the formation of images by lenses and mirrors. On the other hand, in Physical Optics (or Wave Optics) light is assumed to be a wave. Various phenomena such as interference, diffraction and polarization, which cannot be explained by Ray Optics, are studied under Wave Optics.
If you want to be successful in any form of art, you need to practise it regularly in order to hone up your skill. Otherwise, any gap in your practice would slide you back and erase whatever little progress you had made. This way you would find yourself forever beginning from scratch and never making any considerable progress. But easier said than done. If you are an artist, you would know that making a piece of art is easy when you are in mood or it is your hobby, but it loses its charm when you have to perform on demand. And here the demand is ‘regular practice’. Sometimes you do have the will and discipline to get up and sit at your working table, but have no idea where to start — what to draw and how to start with it. Note that here the first stroke is the most difficult step, for once you have overcome that hurdle, then the art would by itself pull you into it. Thereafter it becomes easy. But the first step — the artist’s block as it is called — is the most difficult phase. If you ask me, personally I do not consider it to be any issue. While sketching, I start drawing whatever object is lying in front of me.Continue reading
There are a fixed 24 hours in a day. And also your capacity is limited. You have to manage everything within these resources. You cannot spend your time watching cricket and movies, discussing politics, gossiping, fighting with your spouse, and yet aspire to be an artist, writer, scientist. All these occupations demand enormous concentration, perseverance, practice. A lot many sacrifices have to be made. You have to make a choice — either select the good or the pleasant. If you aspire to rise higher than everyone else, you have to choose the good and let go the pleasant. Unfortunately there is no other way.
Everyone has a vision for the future — how to change the world and how to make it a better place to live. We are nobody to challenge anyone’s personal views, but some ideas look more sound and workable. For example, Nehru was of the opinion that the progress of India can be achieved primarily by science and technology. Post-independence, Prof Sarabhai envisioned harnessing space technology for India’s progress and growth. Indeed, if one looks forward to a bright future for oneself, society, nation or the world, then there doesn’t seem to be any other way than to invest in scientific temperament. Note that by scientific temperament I do not simply mean scientific and technological innovations and inventions, instead I use the term in a rather broad sense which implies looking at the world logically, critically and sensibly.Continue reading
In one of my earlier posts i mentioned the importance of maintaining a harmony among different planes of our being — physical, mental and spiritual. In another post I explored various reasons behind the over-occupation with the physical while ignoring the mental plane. My hypothesis is that this preoccupation is due to an eagerness to impress others who are more likely to see our physical plane rather than the mental plane.Continue reading
Today I am sharing my views on the book Words of Change: Climate — Powerful Voices, Inspiring Ideas by Christina Limpert which I have received for review. This book is a collection of quotes by climate activists from different walks of life and is purportedly meant to encourage and motivate people to think seriously about climate crisis and to join the movement demanding necessary action. Before I give my opinion about this book, I would like to say few words which should help you in appreciating the motivation and scope of this book. When we talk about climate change, a question arises in nearly everybody’s mind — If climate crisis is such a big problem, why aren’t governments doing anything in that direction? Why such widespread and general apathy towards the biggest problem of our times? Yes, I do mean it — one single climate calamity can erase years of development and progress, pushing us several decades into the past.Continue reading
My mentor Prof. Amitabh Sengupta used to say, “Fine Arts is 60% observation and 40% skill. Or I’d rather go so far as to say that it is 80% observation and 20% skill”. He encouraged me to move away from the type of portraits that I had been making till then, and instead invest my skills into practising realism. At first it was difficult for me to break old habits. But the lockdown period last year offered me an opportunity to take a closer look at the objects around me, particularly those scattered around in my house. This sketch of the bathroom shower knob was the first drawing in realism that I made during lockdown last year.
