Wir freuen uns sehr über die Ehrung von Göttingen als 77te "#EPS historic site" und insbesondere auch die reichlichen Erwähnungen von Mathematikern, wie #Hilbert, #Klein, #Courant, #Minkowski, #Gauß und Detlev Buchholz sowie dem Mathematischen Institut (und seinen Vorgängern) während der Verleihungszeremonie.

Space And Time Are One - Minkowski Spacetime Explained

YouTube

▶️ Minkowski Space-Time

❛❛ Points in this #space correspond to events in #SpaceTime ... a defined light-cone associated with each #point, and #events not on the light cone are classified by their relation to the apex as #spacelike or #timelike. It is principally this view of spacetime that is current nowadays ❜❜

Classroom Aid - Minkowski Space-Time

idea:
in #Minkowski space the triangle inequality is opposite — sum of lengths of any two sides doesn't exceed the length of the third one
what if we take a fractal curve (say #Koch) whose length in euclidean space would be infinite (while the curve itself is contained within a finite ball), will it's length in Minkowski space become zero
is it possible to construct such a fractal from time-like line segments and still make the length approach zero
maybe it's possible to construct a space-filling curve with such properties (time-like and zero-length)

Some useful inequalities:

1. Cauchy–Schwarz inequality

\[\displaystyle\sum_{k=1}^na_kb_k\leq\sqrt{\sum_{k=1}^na_k^2}\sqrt{\sum_{k=1}^nb_k^2}\]

2. Hölder's inequality

\[\displaystyle\sum_{k=1}^n\left|a_kb_k\right|\leq\left(\sum_{k=1}^n|a_k|^p\right)^{1/p}\left(\sum_{k=1}^n|b_k|^q\right)^{1/q}\]

3. Minkowski's inequality

\[\displaystyle\left(\sum_{k=1}^n\left|a_k+b_k\right|^p\right)^{1/p}\leq\left(\sum_{k=1}^n|a_k|^p\right)^{1/p}+\left(\sum_{k=1}^n|b_k|^p\right)^{1/p}\]

4. Hardy's inequality

\[\displaystyle\sum_{k=1}^\infty\left(\dfrac{a_1+a_2+\cdots+a_k}{k}\right)^p\leq\left(\dfrac{p}{p-1}\right)^p\sum_{k=1}^\infty a_k^p\]

Right now there's a discussion running on about #RelativisticMass and its relation to limit of the speed of light in vacuum in the TSR
As u would know m0 #MassAtRest is a constant and the m that appears in the expression E=mc^2 is the so-called #RelativisticMass
When four-vectors are built in #Minkowski space,magnitude of energy-momentum is scalar and from there expression E^2 = m0^2c^4 + p^2c^2 is deduced
Concept is useful if it is known how to apply, if not fallacies that populate TSR pop up

Riemann’s Seminal Lecture on Non-Euclidean Geometry

Albert Einstein revolutionized the early conceptions of gravity in 1915 when he presented a theory of general relativity which was based primarily on the fact that mass and energy warp the fabric of…

Who Pioneered the Concept of 4-Dimensional Spacetime

In Newtonian mechanics, space and time were always considered independent of each other. That three-dimensional space — length, width, and height formed the backbone of Euclidean geometry, which was…
