Learning: 1.Twinkling of star is just changing the brightness of star continously. Star appears very small in size because they are very far away from us. 2.Our environment is changing its density continuously due to various reasons like temperature,density of dust, density of gases, air. 3.Due to this reason sometimes more light rays of star come from us and sometimes less light rays. Therefore, they appear to be twinkle. 4.planets don't appear to be twinkle bcoz they look quite big with respect to stars. 5.when some parts of it dims the other part brightens. 6.due to this reason overall their brightness doesn't change. Thanks

As an Indian in the 80's I grew up in the middle East in 'the Indian School'. I think the worst teachers from India got exiled to the Gulf. Because I never learnt anything in science and flunked badly. What sweet irony that now we Indians are the best at explaining things in the world. I feel really sad that we had no access to the internet back then, and instructors like this who are so passionate and genuine. Who knows I might have become something very different in life 😊
