A Sense of Doubt blog post #4047 - This Optical Illusion will Mess With Your Mind



A Sense of Doubt blog post #4047 - This Optical Illusion will Mess With Your Mind

Yes, I know it's St. Patrick's Day.

Not posting about that but I hope you will enjoy yourself whether you are Irish or not.

I was going to go into reprint mode this week, but I decided to just be in unofficial low power mode and just do some easy posts. I have a lot of homework and want to get some writing done and get way ahead on the blog, so some more involved and original posts to come.

For today, just this.

Thanks for tuning in.

From deep in the archives.

This optical illusion of spinning rings will mess with your mind





Master optical illusionist Akiyoshi Kitaoka tweeted this mindbending motion illusion below:

Kitaoka is a professor of psychology at Ritsumeikan University in Osaka, Japan. His research focuses on visual perception and fortunately for us, he shares numerous examples of "anomalous motion illusions" and other optical curiosities on his website.

- Days ago: MOM = 3911 days ago & DAD = 565 days ago

- New note - On 1807.06, I ceased daily transmission of my Hey Mom feature after three years of daily conversations. I post Hey Mom blog entries on special occasions. I post the days since ("Days Ago") count on my blog each day, and now I have a second count for Days since my Dad died on August 28, 2024. I am now in the same time zone as Google! So, when I post at 10:10 a.m. PDT to coincide with the time of Mom's death, I am now actually posting late, so it's really 1:10 p.m. EDT. But I will continue to use the time stamp of 10:10 a.m. to remember the time of her death and sometimes 13:40 EDT for the time of Dad's death. The blog entry numbering in the title has changed to reflect total Sense of Doubt posts since I began the blog on 0705.04, which include Hey Mom posts, Daily Bowie posts, and Sense of Doubt posts. Hey Mom posts will still be numbered sequentially. New Hey Mom posts will use the same format as all the other Hey Mom posts; all other posts will feature this format seen here.
