In English
Even today what the scientists have really learnt is a very small fraction of what there is to learn, but the pride they have accumulated after having learnt such a small fraction is out of all proportion. When we give room to such ego and pride, we are not able to understand even the things which we can understand. The decisions which the scientists are arriving at as a result of their work are being altered in a short time by the scientists themselves. They are criticising and changing the very same conclusion which they arrive at, and there is no scientist who can say that this is the final stage and there is no more to be done.
