The reader will not find here a didactic account of Einstein's theories. Such an account requires the use of the formulre of mathematical physics and would be intelligible only to readers equally at home with these formulre and with physical theories. But, failing such an account, a sort of general survey of the theories of Einstein with a description of some of their aspects seems not impracticable. As we proceed, \\Te shall have to speak of facts and theories well known before Einstein-theories which, when we reflect a little, make""llis new discoveries appear less strange and paradoxical, although not less admirable.
To make a complete survey of the theories of Einstein, we should have to traverse, not only the sciences of space and time, but also mechanics and electromagnetism (including optics ). We have, however, as the title of the book would suggest, dealt mainly with space and time, introducing mechanical and electromagnetic considerations only when they were indispensable.
