Puzzles, perceptions, reality/

 

2018 3 16  Jerry starts a new jigsaw puzzle. 

 I have never been a fan of jigsaw puzzles like   so many are around here especially in winter.   Jerry liked them too.  I found them frustrating.  I   might try to get a few pieces in place but really   was  not interested enough to keep at it.  Short   attention span?  Maybe ,but concentrating on   shapes and fitting them didn't appeal to me. 

   Now words puzz;es like word search, jumble,   even crosswords and I'm in.  I have been doing   Wordle on line daiy now for over a year.  I lost   my original statistics when I had the laptop hard   drive replaced.  Don't understand why since it   was online with the Wordle site, but it happbed.  So I resumed and began again.  But this time I am using online hints before I try my Wordle solution. Onesource I use is Forbes which has ahint and clue, sometimes neither arehelpful to me.  But along with the Wrdle hunt there is commentary and a weekly puzzle.  Sometimes these are not of interest to me but today this solution to yesterday's puzzle was interesting.  

Which square is darker A or B?



Answer,  neither.  It is an optical illusion

I still cannot see it as an illusion,  I'm convinced A is dark and B is light.  Apparently my perceptions rule reality.   

This is called the Checker Shadow Illusion and was created by MIT professor of vision science, Edward H. Adelson, back in 1995. While the ‘A’ square appears darker, it’s just an optical illusion. If you printed this image both squares would use the identical mixture of ink and are displayed with pixels of the same exact color, which is rather astonishing. Just looking at the first picture, I still can’t make my brain accept that they’re the same. Wild! It just goes to show how much our perception of things influences how we think about them—and how unreliable our senses truly are.
