Is our skin colour evidence of Einstein's solution to the photoelectric effect and the (high energy of the) UV photon?

By on
I think I touched on something profound today in class: is our skin colour evidence of Einstein's Nobel Prize work, the photoelectric effect and the (energy of the) photon? 
What Einstein established was 'light photons' increase in energy, in punch, as the frequency increases, and particularly after the ultra-violet in the electromagnetic spectrum. 
(pardon the pun 'particularly' - he is one of the fathers of quantum mechanics and particle photons).

Before the UV frequency, the energy of visible, IR (heat), microwave, and radio light is diminishing and very weak. 
Our skin colour, from this work by Dr Nina Jablonski (Nina Jablonski breaks the illusion of skin color), is determined by our ancestral exposure, or not, to UV - it's UV that kills us. We adapted/evolved skin colour to protect ourselves from the UV.
Light energy after the visible, in the UV, is dangerous to us; and our understanding of this was revealed to us by Albert Einstein and his quantum photoelectric effect paper.  
You may ask why we were talking about this in econ? It was to do with health systems and merit goods.

Natural fractal lake, Arethusa Pool, the worlds only?

Is Arethusa Pool (New Zealand) and its island's the worlds only natural fractal lake? I was there with my family in January: it was a wonderful day, and very exciting for me - mathematically speaking. Arethusa Pool (and its island) is on Mou Waho Island, which is on Lake Wanaka, which is on the South Island of New Zealand, which is in the South Pacific Ocean. Water (the South Pacific Ocean), land (South Island New Zealand), water (lake Wanaka), land (Mou Waho Island) , water (Arethusa Pool), land (islands on Arethusa Pool); water in a puddle after rain (or when I filled it), land as small as a square centimeter inside the puddle, ..... water??   Arethusa Pool, and Lake Wanaka New Zealand 2015.

Fractal Dimension, (Economic's) Elasticity and Complexity

Update May 2017 This is by far my best idea; I have written it up in a working paper at  my academia.edu  and  vixra , and named it:   Quantum Mechanics, Information and Knowledge, all Aspects of Fractal Geometry and Revealed in an Understanding of Marginal Economics. I shall post the Abstract, followed by the original post, followed by the paper. I hope to have someone collaborate and review my work in time. Abstract Fractal geometry is found universally and is said to be one of the best descriptions of our reality – from clouds and trees to market price behaviour. As a fractal structure emerges  – the repeating of a simple rule –  it appears to share direct properties familiar to classical economics, including production, consumption, and equilibrium. This paper was an investigation into whether the mathematical principles behind ‘the market’ – known as marginalism – is an aspect or manifestation of a fractal geometry or attractor. Total and marginal areas (assumed to stand fo

ePublic Goods. Is the internet making new public goods?

Keywords: Public Goods, Internet, Media, Copyright, Market Failure, File Sharing, ePublic Goods An Explanation of the Mass Failure in the Market: the Internet – the Creator of ePublic Goods   First published:October 9, 2010 Update:  May 2017. Blair D. Macdonald. 2017 October: I see Bitcoin and any crypto current as an ePublic Good - it will fail. Abstract Media and entertainment industries are in decline; profitability is down due to ‘freer access on computers. Is the internet producing ‘Public goods’ from what were Private goods? With respect to these goods and the Internet, the assumption used to classify ‘Private goods' and Public goods in an economy (the degree of excludability and rivalry) was analysed, and the respective industries were tested for being Public Goods. It was concluded these goods within the entertainment/media industries are slowly being repositioned from what are termed 'private' or 'club'/'congestion' goods, to t
