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

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

At UV frequencies, the energy of visible, IR (heat), microwave, and radio light decreases and becomes very weak. 
Our skin colour, from this work by Dr Nina Jablonski (Nina Jablonski breaks the illusion of skin colour), 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 beyond the visible spectrum, in the UV, is dangerous to us, and our understanding of this was revealed by Albert Einstein in his paper on the quantum photoelectric effect.  
Why were we discussing this in economics? It involved health systems and merit goods.

Natural fractal lake, Arethusa Pool, the worlds only?

Is Arethusa Pool (New Zealand) and its islands the world's 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, Lake Wanaka, the South Island of New Zealand, and 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 centimetre 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 margin...

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 Abstract Media and entertainment industries are declining; profitability is down due to ‘freer computer access. 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 that these goods within the entertainment/media industries are slowly being repositioned from what is termed 'private' or 'club'/'congestion' goods to their extreme opposite, public goods. The ‘free rider problem’ of Public Goods has become the ‘free copy problem’ with respect to t...
