Gaia hypothesis

Gaia hypothesis
The study of planetary habitability is partly based upon extrapolation from knowledge of the Earth's conditions, as the Earth is the only planet currently known to harbour life The Gaia hypothesis, also known as Gaia theory or Gaia principle, proposes that organisms interact with their inorganic surroundings on Earth to form a self-regulating, complex system that contributes to maintaining the conditions for life on the planet. Topics of interest include how the biosphere and the evolution of life forms affect the stability of global temperature, ocean salinity, oxygen in the atmosphere and other environmental variables that affect the habitability of Earth. Introduction[edit] Less accepted versions of the hypothesis claim that changes in the biosphere are brought about through the coordination of living organisms and maintain those conditions through homeostasis. In some versions of Gaia philosophy, all lifeforms are considered part of one single living planetary being called Gaia.

The Top 37 Things You’ll Regret When You’re Old (Pay Attention To #15) 1. Not traveling when you had the chance.

The Alchian-Allen Theorem The Alchian-Allen Theorem is a lesser known but still very interesting economic theory. It states that when a fixed cost is added to substitute goods, the more expensive one becomes relatively less expensive, and so people are likely to increase consumption of the higher quality good.

Mediocre wine costs $5 to make and good wine costs $10.

MAKERS: Women Who Make America In the last half-century, women have fought their way into nearly every sphere of American life, from the battlefield to the comedy club, the soundstage to the Senate. Expanding on the critically acclaimed PBS documentary MAKERS: Women Who Make America, which told the story of the modern American women’s movement, each documentary in this six-part series examines the impact of the women’s movement on six fields once largely closed to women: business, space, Hollywood, comedy, war and politics. In each field, women have pried open, and profoundly reshaped, the central institutions of American life and culture. Through intimate interviews with trailblazing women known and unknown, viewers are given a rare glimpse-- sometimes funny, sometimes sad, and always candid—of what it was like to be pioneers in their fields.

The Egyptian God Family Tree – Veritable Hokum First: I opened a store! It has a poster of this, as well as updated versions of the Norse and Greek god family trees I did a while back. More to come soon. Next, a disclaimer: this family tree isn’t, strictly speaking, historically accurate, because what we think of as The Egyptian Pantheon is really a whole bunch of similar-but-not-identical pantheons which were mostly based in individual cities – Thebes, Heliopolis, Memphis, etc. – and went through a lot of changes over their 3000+ year history.

Joseph Reagle on the gender gap in geek culture Is geek culture sexist? Joseph Reagle, Assistant Professor of Communications Studies at Northeastern University and author of a new paper entitled, “Free as in Sexist? Free culture and the gender gap,” returns to Surprisingly Free to address geek feminism and the technology gender gap. According to Reagle, only 1% of the free software community and 9% of Wikipedia editors are female, which he sees as emblematic of structural problems in the geek community. While he does not believe that being a geek or a nerd is in any way synonymous with being a sexist, he concludes that three things that he otherwise loves—geekiness, openness, and the rhetoric and ideology of freedom–are part of the problem inasmuch as they allow informal cliques to arise, dominate the discussion, and squeeze out minority views.
