Why Call it Float freely
When my daughter was in class X, I started teaching her physics and Mathematics. Our favourite way to study was what we called 'Float freely". We will start with one topic and from there seamlessly move to a related topic, say I was teaching her laws of motion and so we will start looking at how to draw a graph of velocity vs time and then start figuring out how to find out the area under the curve which turned out to be the distance travelled. The next natural step was to let her figure out why it is so!!! Once she has done it, I will try to show her that integration actually does it!!!!! Or that the area for a uniformly accelerated particle is an area of a trapezium. When we started talking of a trapezium, we will try to figure out that sum of an Arithmatic progression series of numbers can be found by the same formula as that of a trapezium. So somewhere we had connected lot of apparently disconnected things and that was the result of float!!!!!!!
