In the Cambridge mathematical tripods, they said, 'do six questions. Complete questions carry proportionately more marks than an equal number of fragments. Till you attempt half of the questions you won't get full credit'. Upon declaration of result I found that I had scored 110 out of hundred in one paper, 140 in another and likewise in all the rest. I was confused. So my tutor explained to me that although they write 'do six questions', you can attempt as many as you want. They award you marks for whatever questions you answer correctly and the ranks are on basis of the score.

The circumference of earth at equator is 40,000 km and by dividing it with 24 hours (earth completes its rotation in a day), it comes out to 1,667 km. This reverse phenomenon happened at 60 degrees latitude because their jet plane managed a speed of 833.5 km which is half of circumference of the earth.

The Gran Sasso results could be seen as tentatively offering support for the big bang theory – if we could find a way to test that they are indeed travelling backwards in time.

During another examination the question paper read, 'do any six questions, all questions carry equal marks'. But I attempted more than six questions and wrote for the examiner, examine any six questions, all questions carry equal marks.

The study he conducted with Dabholkar goes to explain why astrology is not a science through a simple experiment. They adopted an experiment conducted by Bernie Silverman, a graduate student of Michigan State University, USA. They collected horoscopes of 100 scholarly students and 100 students with learning difficulties.

Space-time in an expanding universe changes over time, so the full quantum description of a neutrino. in that type of universe is different in the past and the future. Neutrinos would behave in both expanding and unchanging "steady state" universes.

There people who were leaders in their field in Cambridge and they lectured. And what impressed me the most was that all these big names never said that they were busy in their research and did not want to be burdened with lectures. They took their part in the lectures actively.

When you claim that the universe started in this particular way you are making a very profound statement. If I make a statement saying that the sun started in a certain way, I would immediately be asked for proof that the sun started in that way. I will have to go around gathering evidence of Solar systems forming, stars forming. I will have to produce evidence saying that this is how new solar systems are being formed, so the sun must have been formed in the same manner. That is a reasonably credible assumption.

Fred Hoyle and Wickramasinghe have argued that microorganims fill up the whole of space. One finds dust and biological molecules between stars. Why not microorganisms? They assumed in one example, E. coli filling up interstellar space and then they calculated how much the absorption of light at different wavelengths from the E. coli model would be. They showed that the extinction curve i. e. absorption curve, was precisely followed for some infra red source. So their argument was that these micro organisms must exist.

I have not been able to relate the idea to the 'faster than light' neutrinos since there are no causality checks to decide if they are travelling in the past.

In western society, there is a problem similar to India that the income of a research scientist is less than that of a management person. But perhaps the facilities and the infrastructure being much advanced in the western universities, they are able to attract and retain the people. In our case this can happen but not to the extent we would like. A corrective measure to some extent has been taken by the establishment of the Indian Institutes of Science Education and Research (IISERs). They are doing for pure sciences what IIT's do for applied sciences. Since they are attracting good talent it may happen that you will have more input in research in the next ten years.

If you see firm evidence of neutrinos arriving at the detector before they are sent, that can't happen in a Steady steady state cosmology, so the Big Bang has to be right. Or equivalently, no faster-than-light neutrinos, no big bang.

So it was better to think of formulations which could explain the creation of matter without violating the law of conservation of matter... For that we used what is called as negative energy, which at that time was considered unrealistic. There was a good example of negative energy, mainly Newtonian gravity. Newtonian gravity is a negative energy system because gravitational potential energy is negative and we i. e, Fred Hoyle and me, worked out a fairly consistent method of describing this whole thing. Today what people call phantom fields, an idea which is catching up with people trying to explain some problems of the big-bang, these phantom fields are what we had proposed way back in the 1960's.

A black hole is the ultimate manifestation of a region of strong gravity. The pull of gravity in a black hole is so strong that even light cannot escape from it and time stands still.

Science in India is getting better support now than in the past... Doing research has changed in the way that it is very grant oriented. The mentality that some accepted paradigm must be believed has become more rigid.

In the Vedic era, there was never a seven-days-a-week concept. Similarly, astrologers were also not known at the time. They came later, when Alexander came to India and brought several of them along with him. Indians carried forward astrology.

We all know that sun rises in the east and sets in the west, and earth spins on its axis from west to east. But on that day my jet plan was at 60 degree latitude near Greenland and the plane exceeded the speed of rotation of the earth on its axis so the sun was found moving from west towards east.

Cambridge was my goal, so once I got admission and scholarship, I decided to go there - I went there after my B. Sc at 19, I did my Masters in 3 years, by age 22 and PhD in another 3 years, by 25 years of age.

Now with the big bang there is only one event that happened. So like the sun you can't say that there are other big bangs going on that are what ours was like. The second problem is that at the big bang mathematics and physics break down. So there is no way of mathematically describing it. That is not a satisfactorily scientific approach, to ascribe something to speculations which you cannot justify using mathematics and physics.

Science popularization involves information about science explaining the things and their implications in detail, or any beliefs the reader might have and also tell them about the newer discoveries so as to enlarge the persons horizons.

Found that in a universe that is expanding after a big bang event, neutrinos would turn up at a detector before they were emitted. Only future-going neutrinos were possible in the Steady state cosmology while the ever-expanding big bang models gave neutrinos travelling into Steady State theory to the past.

In our theory we have multiple mini bangs and these mini bangs are not mysterious like the big bang but they come because of the concentration of what we call negative energy fields. Whenever there are pockets of negative energy, they explode and produce a mini bang. We believe there's a mini bang producing energy in the centre of quasars, which are very bright star like objects. Gamma ray bursts, which are the explosive creations of gamma rays, are another example of a mini bang. These are actually happening. These can be described by normal physics, but the big bang cannot. The big bang theory does not use any mathematical formulation so they can't say why the bang occurred.

It was around dusk when my companion and I noticed the position of sun closer to the west horizon, and the sun was going up.

We have seven colours — violet, indigo, blue, green, yellow, orange and red (Roy G. Biv). Our atmosphere has a number of particles and when light falls on them, it gets scattered. With blue colour having less wavelength and more scattering qualities, it scatters and makes the sky blue. While red colour has opposite qualities than blue so traffic lights are of this colour.

In 1963, when I completed my PhD, it was mostly on the steady-state theory using mathematical formulations to describe creation of matter. People always argued that you cannot have matter coming out of nothing, what would happen to the law of conservation of matter. It is a normal criticism of the steady-state theory. One could answer it either in one sentence by saying what is the big-bang theory where the entire universe came out of nothing, so you are violating the law of conservation of matter and energy in a big way. But that would be to point out the weakness of the other theories and not answering your own theory.
