Of Two Minds

I’m teaching about opponent processes in color vision today and thought I’d share one of my favorite examples. This is how you use the human visual system to turn a black and white photo into color. Try it out:

I’m in the middle of my qualification exams and ran across this interesting paper: Liu, Z Kersten, D Knill, DC Dissociating stimulus information from internal representation–a case study in object recognition. Vision research. 1999; 39(3): 603-12. However, I’m very confused about them calling the figure on the left an object. This is a collection of…

I think it’s a bit like terrorism. It scares the shit out of you but there’s next to zero chance it will actually happen to you. Seriously… you have a much much higher chance of choking on a twinky (even if you’ve never eaten one) than catching the swine flu and dying or being or…

Straight from XKCD… I had this exact same reaction. Now that we’re on the topic. I don’t like federal money going to pay bonuses but seriously… this money was promised long ago and it’s already been given out. Using the tax code to take it back? Wow this is seriously a real cluster @#$!

I’m not sure what this whole thing is about since at no point did Obama make fun of the Special Olympics as an organization – he straight up made fun of retarded people (or whatever the P.C. term is nowadays). Here’s a little snippet from People: President Barack Obama’s lighthearted Thursday night appearance on NBC’s…
