Carl Sagan testifying before Congress in 1985 on climate change

"We are pouring #carbon #dioxide and other #gases into the #atmosphere with hardly any concern for its long term and #global-effects ... the #solutions to these #problems requires a #perspective that embraces the #planet and the #future because we are all in this #greenhouse #together."

The Pale Blue Dot - Le Point Bleu Pâle

Tu n'es pas si important que cela...

Carl Sagan, Le Point bleu Pâle :

Depuis ce poste avancé, la Terre ne semble pas avoir grand intérêt. Mais pour nous c'est très différent‎. Regardez encore ce petit point. C'est ici, c'est notre foyer. C'est nous. Sur lui se trouve tous ceux que vous aimez, tous ceux que vous connaissez, tous ceux dont vous avez entendu parler, tous les êtres #humains qui aient jamais vécu. Toute la somme de nos joies et de nos souffrances, des milliers de religions aux convictions assurées, d'idéologies et de doctrines économiques, tous les chasseurs et cueilleurs, tous les héros et tous les lâches, tous les créateurs et destructeurs de civilisations, tous les rois et tous les paysans, tous les jeunes couples d'amoureux, tous les pères et mères, tous les enfants plein d'espoir, les inventeurs et les explorateurs, tous les professeurs de morale, tous les politiciens corrompus, toutes les "superstars", tous les "guides suprêmes", tous les saints et pécheurs de l'histoire de notre espèce ont vécu ici – sur ce grain de poussière suspendu dans un rayon de soleil.

La Terre est une scène minuscule dans une vaste arène cosmique. Pensez aux rivières de sang versées par tous ces généraux et empereurs afin que, glorieux et triomphants, ils puissent devenir les maitres éphémères d'un petit morceau d'un point.

As a mathematician, I always feel alienated, because of how little people know about maths, and because every non mathematician just scares when you start explaining something, even the easiest thing. “Oh, please, stop. Anyway I won’t get a thing”. This is the regular reaction of people.
Most people don’t know what #math is. But the worst part is, that they not only don’t know, they don’t want to know. Math scares them. Even physics doesn’t scare them as much, as math. Maybe because there is something that can be shown. (And also due to the great books of Stephan #Hawking and Carl #Sagan) But when it comes to Mathematics, everything becomes more complicated, because you can’t show it. It’s too abstract. And, it even doesn’t really exist. :)
So, I don’t have to say how much I appreciate when I see a popular #book about #maths. For me, as a reader, Edward #Frenkel's book “Love and Math” was a great read. (especially the beginning of the book, last chapter or two were bullshit…ehm, sorry). He showed how much Math mattered. He showed that it’s not a tool for #physics, but it can be the one which directs it.
Today I wanted to write about other book, a comic book about #logic “Logicomix”. When I started writing this post, I realized that what I want to say and how I feel about this book, is not quite about the book. This book. It’s more about my view of math, and how it should be represented to non mathematicians. And my concerns about this book are not relevant. They have done what they thought was important, telling all these stories about #Russell and war, and not paying that much attention to #Gödel, #Turing and Von Neumann. (Actually there was too little math in it. But I was very impressed when they wrote about #Frege (without explaining his system, without pointing out differences between Frege’s and #Aristotle's systems)).

Now I’m considering writing small blog posts on math for non mathematicians :)
