Christian Lawson-Perfect @christianp@mathstodon.xyz@liseo there are lots of ways of representing colours numerically. The most basic way that computers use is to use a number between 0 and 255 for each of the red, green and blue components, called RGB encoding. The problem with that is that colours that look close to each other don't necessarily have close RGB values. There are other colour spaces which try to get closer to the ideal of having similar colours close together. Oklab, which I use in this tool, is currently the best for that.

one of the problems of the double 00:44:14 bind is that you are often so caught in the extreme drama of the situation that it becomes very difficult to see beyond it

Many people are frightened of mathematics and thinkthey cannot read it at all. No one is quite sure why this is so.Some psychologists think there is such a thing as "symbolblindness"-the inability to set aside one's dependence on theconcrete and to follow the controlled shifting of symbols.

today what I'd like to do, if you're willing, is start to construct a framework for how we start to prepare for what's ahead. What is the hard work that's going to make need to be done? And what are the buckets that people and governments need to focus on?

Please welcome a return to this show my Australian colleague Simon Michaux. Simon currently works for the government of Finland in their mining geology division called GTK. Simon and I previously had a conversation called Minerals Blindness, which complimented the term often used on this podcast, energy blindness. 00:00:26 Simon Returns today to give an overview on given the biophysical constraints that we face, how do we think about solutions? And what would be a preliminary framework for research and societal interventions for what we face?

Whites profit off of an American political and economic system that showers advantages on racial “winners” and oppresses racial “losers.” Yet, DiAngelo writes, white people cling to the notion of racial innocence, a form of weaponized denial that positions black people as the “havers” of race and the guardians of racial knowledge. Whiteness, on the other hand, scans as invisible, default, a form of racelessness. “Color blindness,” the argument that race shouldn’t matter, prevents us from grappling with how it does.
