Hello guys! I want to share some interesting things about science with you. First of all what's science? According to me science is a way to understand the law of nature. If you observe, you face hundreds of basic science principle in your daily routine life. But what you need to do is to observe it & raising question why this is happening? Once you raise question in your mind, you'll get knowledge about it & you'll learn something from it. For your convenience let me give you an example :- Imagine that you're lifting a heavy bucket or anything by the help of your one hand & you're walking. At this time if you observe your body, you'll find that you raise your another hand little bit & bend your body in opposite direction from your heavy bucket side. We do this to balance our body & lift the weight the weight easily. Hence is an interesting science phenomenon which is used all over the world. We've already experienced many science phenomenon but scientifically we don't know about it. That's it I want to share. If you want to know more about some interesting fact then comment. Thank you!
