Deuterium:also known as heavy hydrogen) is one of two stable isotopes of hydrogen (the other being protium or hydrogen-1). The nucleus of a deuterium atom,called a deuterium,contains one proton and one neutron,whereas the far more common protium has no neutron in the nucleus.
The scientist who wrote the universal law of gravitation was Sir Isaac Newton.
Contrary to popular belief the scientific method is an iterative process because scientists often have to revisit, repeat or revise previous steps. It is very common for an experiment to be done many times in different international laboratories in order to confirm that a conclusion is valid. All good scientific experiments should allow results to be replicated.
