Today I finally dared to do the most dreaded exercise, The Pull Ups.
Dreaded in the sense that it requires and recruits all the major muscles of upper back
and arms and forearms.
To my great relief and joy I was able to do 3 sets of 5 repetitions each.
It is amazing how strong the connective tissues laid down by the fibroblasts are.
Fibroblasts are cells that synthesize extracellular matrix and collagen which form
the structural framework of any organism.
The fibroblasts play a critical role in wound healing.
They are the factory for synthesizing collagen, glycosaminoglycans, reticular and
elastic fibres and glycoproteins found in the extracellular matrix.
In 1913, when Moseley was just 26 and had moved to Oxford leaving both Rutherford and Manchester, Mendeleev's periodic table had turned 44.
Moseley noticed that the table had a basic bug (remember that it was based on atomic weight).
The place that the atomic weight assigned to an element did not always correspond to the chemical properties.
Meanwhile, a Dutch lawyer and a greenhorn physicist by the name of Antonius van den Broek published a paper in "Nature" on July 20, 1911.
It was published just a month after Rutherford had published his 1911 landmark paper:
"The Scattering of alpha and beta particles by Matter and the Structure of the Atom".
In that paper, Van den Broek put forth the idea of the direct correlation between the charge of an atomic nucleus and the position of element on the periodic table.
Rutherford had missed this completely.
This paper of van den Broek intrigued Moseley at Oxford.
Moseley had learnt from the father son Bragg duo that if high energy electrons were made to hit the solid metals (thin films of course), the solid emitted X-rays.
At Oxford, Moseley had laboratory but no funding (money).
His genius shone forth at this moment.
Within a short span of time he himself designed an apparatus to shoot high energy electrons at different chemical elements and measure the wavelengths of the emitted X-rays.

It is a moment worth pausing and contemplating on this apparatus setup.
It is a pity that an experiment so beautiful and so revolutionary is so little known or taught.

Good night mon ami and my fellow cousin ape.
