Throughout the development of mechanics and electromagnetism the role of space and time had been clear and simple. Space and time were simply the arena within which the drama of physics was played out. All that changed with the advent of the theory of relativity.

The reader who perseveres will have read one of the most influential papers in the history of physics. The accompanying notes and illustrations should, we hope, make this foundational document of special relativity understandable to anyone with high-school level mathematics. Universal intelligibility was a major goal of the early workers in relativity: Einstein famously not only wrote several popular accounts of his ideas, but even used one such popularisation to introduce a version of his unified field-theory. Minkowski's essay given here -- the work for which he is most remembered outside the world of pure mathematics -- was first given orally to an audience composed of scientists but not primarily of physicists. We hope that this republication of it continues the tradition of making important works of natural philosophy accessible to all.

## Relativity without Spacetime

As an alternative to a planar Minkowski space-time of two space dimensions and one time dimension, we replace the unit imaginary , with the Clifford bivector for the plane that also squares to minus one, but which can be included without the addition of an extra dimension, as it is an integral part of the real Cartesian plane with the orthonormal basis and. We find that with this model of planar spacetime, using a two-dimensional Clifford multivector, the spacetime metric and the Lorentz transformations follow immediately as properties of the algebra. Based on the mathematical structure of the multivector, we produce a semi-classical model of massive particles, which can then be viewed as the origin of the Minkowski spacetime structure and thus a deeper explanation for relativistic effects. We also find a new perspective on the nature of time, which is now given a precise mathematical definition as the bivector of the plane.

In different sources Minkowski's nationality is variously given as German, [3] [4] [5] Polish, [6] [7] [8] or Lithuanian-German, [9] or Russian. Minkowski is perhaps best known for his work in relativity , in which he showed in that his former student Albert Einstein 's special theory of relativity could be understood geometrically as a theory of four-dimensional space—time, since known as the " Minkowski spacetime ". He married Auguste Adler in with whom he had two daughters; the electrical engineer and inventor Reinhold Rudenberg was his son-in-law. David Hilbert 's obituary of Minkowski illustrates the deep friendship between the two mathematicians translated :. The main-belt asteroid Minkowski and M-matrices are named in Minkowski's honor. He also became a friend of another renowned mathematician, David Hilbert.

## The restless Universe

This volume is dedicated to the one hundredth anniversary of the publication of Hermann Minkowski's paper "Space and Time" in His work on the spacetime representation of special relativity had a huge impact on the twentieth century physics to the extent that modern physics would be impossible without the notion of spacetime. While there is consensus on the mathematical significance of spacetime in theoretical physics, for a hundred years there has been no consensus on the nature of spacetime itself. We owe Minkowski a clear answer to the question of the nature of spacetime -- whether it is only a mathematical space or represents a real four-dimensional world.

Он заместитель директора Агентства национальной безопасности, а сегодня все, что он делает, важно, как. Его дыхание стало ровным. - Сьюзан. - Голос его прозвучал резко, но спокойно. - Тебе удалось стереть электронную почту Хейла. - Нет, - сконфуженно ответила .

К нему приближалась девушка, с которой он столкнулся в туалетной комнате. Она помахала ему рукой. - Подождите, мистер. Ну что еще? - застонал. - Хочет предъявить мне обвинение во вторжении в личную жизнь.

Ей казалось, что пар буквально выталкивает ее наверх, через аварийный люк. Оказавшись наконец в шифровалке, Сьюзан почувствовала, как на нее волнами накатывает прохладный воздух. Ее белая блузка промокла насквозь и прилипла к телу. Было темно. Сьюзан остановилась, собираясь с духом. Звук выстрела продолжал звучать у нее в голове. Горячий пар пробивался через люк подобно вулканическим газам, предшествующим извержению.
