Product Description

Space Time Continuum 15.55gm Silver

Space Time Continuum 15.55gm Silver: The term space-time was created by the mathematician Hermann Minkowski who, in 1908, mathematically proved that space and time cannot be separated from one another. Interestingly, he was the teacher of a certain Albert Einstein at the Polytechnic Institute in Zürich.

When in 1905, Minkowski heard about the development of the special theory of relativity by his former student, he apparently said: „I would not really have expected that from Einstein“. However, it was Einstein who set the biggest milestone in the research of space-time curvature so far in 1915, with his general theory of relativity.

Our first delve into the new releases is a particularly ambitious design and must surely push the boundaries of just what is possible with a mechanical strike. Designed around a mathematical representation of spacetime, the concept that takes the old standard three dimensions of space and the seperate fourth dimension of time, and combines them into a single manifold called Minkowski space. The sheer three-dimensionality of the coin is extremely impressive and the way the pattern of lines has been struck into the coin while maintaining shape is of particular note. Seen from the side, it’s clear this is a very unique numismatic. The addition of a small magnetic ball representing a cosmic body, maybe the Earth, is a great touch and further lifts this release from the ordinary.

The reverse of the coin depicts the Minkowski diagram, a geometric illustration of the formula of special relativity, which is engraved in one of the diagram’s columns together with the inscription SPACE–TIME CONTINUUM. The center of the high-relief coin is marked with a magnetic sphere, which can be removed.


The obverse, whose shape is a mirror or inversion of the reverse, displays the Ian Rank-Broadley portrait of Queen Elizabeth II, the issuing nation and the face value.
