## Albert Einstein debates with Emmy Noether

LoopdoctorsAugust 16March 11Level III Doctor

Emmy and Albert knew each other very well. However Einstein never incorporated seriously the brilliant ideas of Emmy Noether. On the homepage of this site we organised and filmed a short virtual debate between the two. So herewith we correct history afterwards for the better of Physics! The film is going pretty...

Contrary to popular believe, there are many Schwarzschild Solutions. Karl himself found one to a mass-point and one to a sphere of in-compressible liquid early 1916. After Karl’s death Einstein made important changes in his official publication: he abandoned his g = -1 requirement in a footnote. Nobody checked...

## Mysticism in Relativity

LoopdoctorsMarch 30April 20Level I Student

How many people understand Relativity? Many say they do, but how do they explain the paradoxes of Special Relativity (SR)? Do they know that Einstein changed his mind about his own SR in 1916? They should know that he abandoned the equality of reference frames already in 1916, solving the twin paradox. Then Einstein...

## Relativity Solutions need repair

loopdoctorFebruary 20February 200Level III Doctor

Einstein’s publication in the ‘Annalen der Physik’ urged many scientists to work. Did you know that there are five different Schwarzschild Solutions? How do you know which one is right? This article presents you three ways to check the outcome: The General Relativity Principles, the GR field equations and the Laplace...

## Time and Repairing the Schwarzschild Solution

loopdoctorFebruary 18July 110Level II Advanced

In his theory of General Relativity, Einstein replaced the Lorentz transformation by the Minkowski formula. He also introduced the variable speed of light in gravitation. This is unnecessary and untenable: it is in conflict with Noether’s theorem on energy and momentum conservation. The authors use the ‘time’...

## No ‘Event Horizon’ in New Time-like Solution

loopdoctorFebruary 15March 160Level III Doctor

Einstein’s General Relativity contains the Laplace operator of a sphere of incompressible liquid. It links the time-like solution (how fast does the clock tick) directly with the gravitational potential: no need for using tensor operations. He never applied it to the potential inside a sphere. This article is doing...

## Emmy Noether, the ignored scientist

loopdoctorDecember 4February 190Level I Student, Level II Advanced, Level III Doctor

It all starts with Emmy Noether (1882 – 1935), a brilliant mathematician, creating one of the pillars of physics: defining reference frames within which energy and momentum conservation can be proven. In 1918 Noether’s theorem was published, more than a year after Einstein published his theory of General...
