The history of tea - Shunan Teng

Used since 6000 thousand years ago, at the beginning eaten as vegetable with green porridge
New way of preparing it discovered: heat tea-leaves + pulverize + water = Matcha 
Tea art existed just as the contemporary espresso art (draws in the coffee cream). 
Dutch carried tea to Europe, which was a huge income for China,
then Queen Catherine of Berganza of Portugal (heavy tea drinker) married King Charles II of U, she popularized the tea to UK which then propagated the culture to all their colonies.
Tea 10 times the price of coffee and Britain paid with silver which was too expensive... 
British started trading with Opium, which poisoned China population. The Opium war starts, in 1842 Chin dynasty loses to UK (Hong Kong is seized). 
China will have to keep trading in unreasonable terms, but still British wanted more, they sent spies to smuggle tea trees and create a production in India (which is nowadays one of the biggest consumer and exporters of tea)



A brief history of goths - Dan Adams

VisiGoths-OstroGoths main enemies of the Western Roman Empire
Mercenary revolt that captured Rome, Theodoric was made King of Italy
It fragmented the empire into kingdoms ruled by Goths and other Germanic tribes. 
Roman culture influence declined, religious symbolism and allegory rather than proportion and realism. 
Constructions (e.g. Cathedrals) with pointed arches, large windows, make the structure more skeletal, allowing an open luminous interior.

Cathedrals with this style were built all around Europe, until the Renaissance movement renew the admiration for Ancient Greece and Rome; seeing the Goth buildings as rude and inferior, describing it as Gothic as a derogatory term. 
1700 Enlightenment movement, Scientific above all else; concern for art/nature the new literary genre Gothic rised, gaining special strength with Poe. Inspiring classics (Frankenstein, Dracula, Doctor Jekyll, etc.)
1970 musical scene (The Doors, Velve Underground, Joy Division, Bauhaus, The Cure) combined gloomy lyrics and punk dissonance with imagery inspired by the Victorian era, classic horror and androgynous glam fashion. 
1980 Music genre being described as Goth music 

This is the tendency for civilization to reach into it's past to reshape it's present.



Where does gold come from? - David Lunne

Over million years fusion transforms Hydrogen into Helium, Carbon, Oxygen, Iron, Niquel. At that point nuclear fusion doesn't release enough energy and the pressure from the core reduces and the outer layers collapse into the center and bouncing back, exploding and forming a supernovae. Pressure is so hard that subatomic protons and electrons merge producing Neutrons, which mean no repelling electro charge, so it is easier for metal elements (like the Iron group) to capture those Neutrons, multiple neutron captures transform the Iron into Silver, into Gold, into Lead and into Uranium, in that order.
Hydrogen to Helium takes million of years, the creation of heaviest elements in the supernovae takes place in seconds.
Using particle accelerators, mimic nuclear reactions creating gold but ATOM by ATOM, so it will be impossible to even create 1 gram.

One excellent Ted talk

a globally interesting topic, but wtf does a social geographer does? is he saying positive things about the planet and our civilization? what? I had for some years the misconception of accepting "logic only", considering beauty and visuals as not relevant/ not valuable, here a proof of the importance of having proper data recollection (no generalization fallacies, no only one's individual opinion) mixed with a clearer way of presenting that data

Empezar en un Hostel (Una de las mejores decisiones que he tomado)

Nunca habia pensado en hospedarme en un hostel (tenia prejuicios, me imagine un lugar demasiado barato, malo,  que tipo de gente “negativa” iria allí, perder privilegios como dormitorio/banio privado, etc.). Pero, quería mudarme a Londres. Al buscar, tantee aspectos positivos como: La vibra social, abierta y con seguridad que tiene la ciudad (o lo que lei de ella) no hacia parecer al hostel como algo extranio o negativo No soy ningún millonario y quería tomarme suficiente tiempo para encontrar trabajo (Viendolo en retrospectiva queria hacer Turismo/Diversion primero) Llegar a una ciudad nueva, donde no conoces a casi NADIE (gracias Primo!) y empezar a trabajar después de hospedarte en un Hotel (donde no conoces a nadie), me sonaba como una experiencia peligrosa. Soledad mortal. Despues de pensarlo bastante, me decidi por un Hostel y seria Astor Queensway, por las reviews parecía un hostel menos CORPORATE. Un enfoque mas amigable, mas tranquilo y menos “vamos a meter ...
