Which scientist developed theory of gravity?

Link
They theory of gravity was developed by Sir Isaac Newton. He was an English mathematician.He formulated the theory of gravity in his groundbreaking work in the year of 1687. In this work, he introduced the law of universal gravitation.

Mathematical: F = G ( m1.m2)/ r^2
In this equation
F = force
G = gravitational force
m1,m2 = two masses
r = distance

According to this formula the definition of the law is. The force of the masses which attracts each other is directly proportional to the product of masses and inversely proportional to the square of the distance between objects.

How many total bones present in a newborn and adult?

Link
There are about 270 bones in the human skeleton.When the baby grows the bones fuse with each other, which results in decrease in the bones in the total number.With the time when the body reaches the adulthood the no of bones reaches to 206.The functions of the human skeleton are: it provides support, it protects our internal organs, facilities movement of the body, produce blood cells, and store minerals.When a baby is born, the skeleton is made up of cartilage, that gradually ossified and convert into bone. When that baby reaches the adulthood the bones fuse together and the number of the bones decrease in the body.
•Bones of the skull:

These bones are frontal, temporal, parietal and occipital, when they fuse together they form a skull which contains few bones.

•Pelvis bones:
The bones also have fusion process. In a newborn, the pelvis has many bones and after fusion they a form a pelvis.

•Spine:
The spine is made up of vertebrate individually in newborns. As the baby grows, few of these bones fuse and form large bones.

•Hands and feet

The bones of the feet and hands also fuse together. There are numerous bones in a newborn baby as compared to an adult.
