I have seen some different opinions on the French :
"On the polarization of light the Frenchmen have nothing but nonsensical theories on undulations and homogeneous light, besides computations which are not based upon anything. They are constantly in a haste to measure and to calculate ; they consider this as the main thing, and their slogan is le calcul! le calcul! But I say, Où le calcul commence, l'intelligence des phénomènes cesse: he who has only numbers in his head cannot find the trace of the connective cause."

$v_{l \pm n} = v_{l }$ where as $v_l$ is a base vector. for $l = 0...n$
i want ot show that the operator give throught $\sum_{l=1}^n v_l \phi_{l-1}$
$\phi_l= <v_l, ->$ is hermetian.+
the heremtian of $v_l$ is $\phi_l$ and that of $\phi_{l-1} $ is $v_{l-1}$
This is physics so dont ask about details, none are provided
some hilbert space of quantum mechanical mumbo jumbo
so the hermetian is given through $ \sum_{l=1}^n v_{l-1} \phi_{l}$
Now i need to show that thi is aquivalent. i thought, i show hte sums are the same, which i dont think they are... then, lets try to apply a random base vector…

category theory literally be like: A [[Category]] consists of a collection of objects $X, Y, Z, ...$ and a collection of morphisms $f, g, h, ...$ such that:
i) each morphism has an object as its domain and codomain, denoted by $f: X \rightarrow Y$,
ii) each object has a designated identity morphism, denoted $1_X: X \rightarrow X$,
iii) for any pair of (composable) morphisms $f: X \rightarrow Y, g: Y \rightarrow Z$, there exists a specified composite morphism $g \circ f: X \rightarrow Z$,
iv) (Identity Law) for any $f: X \rightarrow Y$, $1_Y \circ f = f \circ 1_X = f,$

> Hörbiger had various responses to the criticism that he received. If it was pointed out to him that his assertions did not work mathematically, he responded: "Calculation can only lead you astray." If it was pointed out that there existed photographic evidence that the Milky Way was composed of millions of stars, he responded that the pictures had been faked by "reactionary" astronomers.
He responded in a similar way when it was pointed out that the surface temperature of the Moon had been measured in excess of 100 °C in the daytime, writing to rocket expert Willy Ley: "Either you believe…
