My grandpa Hertz is the best scientist of all , because he discovered the radiowaves and he showed the experimental evidence of electromagnetic waves.
I disagree, because my grandpa Maxwell is the best! , because he contribute the Maxwell's Equation that showed the relation of electricity and magnetism.
buttttttt!!!!!! my grandpa Oersted is the great of all scientist becuase he discovered the electric current sent through the wire produce a magnet.
All your grandfather are weak! my grandpa Ampere demonstrate the magnetic effect based on the direction of current.
All your grandpa are really great but My Grandfather Faraday is the best scientist in the world, he is the father of electromagnetic induction .
All of your grandfather are really great becuase of they we have a knowledge about science and without them we have not technology that help us to make the things easy so cheer up guys! all contribution of your grandfather is veary important to us. .
