Why there's a need to study on how to read and write numbers in scientific notation especially in physical science?

Because when you are working with large numbers, scientific notation is much less prone to error. Writing the size of the galaxy in miles for instance, the galaxy is approximately 6,000,000,000,000,000 miles across. Writing that in scientific notation is much neater, and easier.

6.0 x 1015 So it saves a lot of time and effort, and is a lot easier to be sure you are being accurate.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
