Crystals of time
With title “crystals of time” I am jumping into the future. Indeed, yesterday I received email from one of my colleagues in Russia. He brought to my attention the recent news about “time crystals“: Scientists unveil new form of matter: … Continue reading
Elliptic m-deformed relativity
According to Wikipedia special relativity theory was originally proposed in 1905 by Albert Einstein. But Wikipedia is not always the best source of information. For instance Wikipedia has a section about “Causality and prohibition of motion faster than light“. Quite … Continue reading
Moving to imaginary time
Before moving to imaginary time let us warm ourselves up first doing a small exercise while still in real time. We did not quite finish our business with periods of elliptic functions in the last post “Periods of Jacobi elliptic … Continue reading
