And of all the significant figures they considered for that honor, the one they ended up choosing was Albert Einstein. And on the face of it, this is really a remarkable decision, because Einstein, he was a theoretical physicist, heContinue reading “Albert Einstein. Why this name simbolize a revolution on science”
LISA’s work is the result of many sacrifices that allow the beginning of the era of gravitational astronomy. Why that? LISA Pathfinder has gone through a long series of tests, implemented and corrected in order to exceeded all expectations, and it is with this result that the ESA work, the Italian Space Agency (ASI), the National Institute of Nuclear Physics (INFN) and the University of Trento has been awarded.
Thanks to Lorentz transformation (name given by Henrì Poincarè) we have a theory that aim to give a scientific description of the change of viewpoint from one inertial frame to a second moving one. This specific change of viewpoint is called a (Lorentz) boost. Why Lorentz transformations are so important for human knowledge? His formulaeContinue reading “How Lorentz transformation improve the knowledge on space-time concept”
