If you are a Physician, a Thamatic student and if you do not know who this person is, then you have best performed the greatest crime because he is the Jusaya Willett Gibbs from the Yale University who has invented modern vector notations, which means that even up to the 19th century Newton's laws were written independently in the three directions like this. But a Jusaya suggested that all three of these equations would be replaced by a single vector equation which looks like this and made our life very easy as a Physic and Mathematics student. So if you didn't know him, now you do and for more such Physics and Mathematics related facts, subscribe to my channel Sigma Physician.
