In the previous chapter of this series, we went over the subjective, relative separation of the network of events known as Spacetime into space and time. The speed of light played a major role in the discussion.
In particular, we […]

The division of past and future
In Part 1 of this series, we presented the empirical fact that under extreme circumstances, a certain observer’s past can be in another observer’s future. To explain this, we introduced the network of […]

Observations vs intuitions
Einstein’s Theory of Relativity introduced us to the concept of Spacetime, as a unified entity. This stands in contrast with the intuition that we develop since birth, which leads to naturally separate space and time.
Human intuition […]

Superconductors are a particularly strange kind of metal. What makes them different is their behavior at very low temperatures – extremely low, that is, close to absolute zero. Basic thermodynamics dictates that in this regime we should expect all motion […]
