In Continuity With The Past: Indigenous Environmentalism And Indian Christian Visions Of Flora, James Ponniah
In Continuity With The Past: Indigenous Environmentalism And Indian Christian Visions Of Flora, James Ponniah
Journal of Global Catholicism
This article considers whether Indian Christianity can be said to have a distinctive ecological vision. The first two parts of the article examine Christian environmentalism in two native forms of Indian Christianity: Tamil Christianity and Tribal Christianity. Continuing with the theme of conformity to the local culture—though of the elite—the third part of the article investigates how Christian Ashrams function as dynamic centers for ecological praxis. The last part of the article considers how contemporary Indian Christian communities can respond to the ecological challenges confronting them.
A Beautiful Proof By Induction, Lars-Daniel Öhman
A Beautiful Proof By Induction, Lars-Daniel Öhman
Journal of Humanistic Mathematics
The purpose of this note is to present an example of a proof by induction that in the opinion of the present author has great aesthetic value. The proof in question is Thomassen's proof that planar graphs are 5-choosable. I give a self-contained presentation of this result and its proof, and a personal account of why I think this proof is beautiful.
A secondary purpose is to more widely publicize this gem, and hopefully make it part of a standard set of examples for examining characteristics of proofs by induction.
