Sir Isaac Newton and his colleagues enjoyed studying and expanding the supposedly unequivocal laws of physics, such as Newton’s three laws of motion. During the twentieth century, theories such as Einstein’s relativity and those in quantum mechanics turned Newton’s world upside down. Today, a lot more is known about quantum mechanics. However, there is a still an unknown world between Newton’s and Feynman’s. One example of this gap is Schrodinger’s infamous cat.
