Unlike many scientists who work with microscopes, telescopes or some kind of laboratory equipment to perform experiments in order to solve problems they are working on, or find the answers they are looking for, Albert Einstein was a different kind of scientist. He did not perform experiments to prove his theories. He devoted his entire genius to conceiving. (构想) and developing (推导) ideas, and then turning them into written mathematical formulas.
Some of Einstein’s theories were so far ahead of their time that they could not be tested until years later when better scientific instruments and equipment had been invented. For instance, one theory pointed out the existence of a certain star that nobody had ever seen. Another predicted that an atom, then considered the smallest particle (粒子) in the universe, was actually composed of even smaller particles. Eventually both theories were proved to be true.
Albert Einstein gave the world many new mathematical formula
A. in his mind
B. in his laboratory
C. with microscope
D. with telescopes

Many people who work in London prefer to live outside it, and to go in to their offices or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening.
