Description automatically generated with medium confidenceThis is the 3rd generation of my personal website, driven by changes of Internet Service Providers. I have my own domain name, PERSJOHN, made up of the first four letters of both our surnames, Diane Persson and Daniel Johnson.


A picture is worth a thousand words, but digital images often chew up file size and bandwidth so I lean toward text for my website, so people can browse and decide whether to look at more before clicking the link.


My 2008 retirement road trip covering almost 80 days and 15,000 miles is here  (or just see the map of my travels), and as I’ve always loved maps here’s my population cartogram of Texas and a map of US population from the 2010 census with a page of details. Diane and I started a blog in 2010,, and went to teach English in China for two years, first at the Baotou Teachers’ College in Inner Mongolia, where the students asked how many countries I'd visited, and to help answer I made a map of all the places I've visited in my life, with color highlight for places I've lived. In 2012 we were at a different place in China, Qinzhou University on the south coast near the border with Vietnam. We returned to Houston in 2013 and spent the summer in Canada, with trips on "The Road Less Populated". In 2014 we spent a month in France and hiked the Cotswold Way in England. In 2015 I designed my golden logo to celebrate 50 years in science, and we rented a condo on Vancouver Island for three months in the summer and went on to buy a condo of our own in Victoria. In 2016 we were there for the whole summer, again in 2017 except a month in Europe, in 2018 after a month in China, and in 2019. Covid kept us in the US in 2020, but we took road trips and finally flew back to Victoria after summer was almost over, so we stayed into the New Year, 2022.

My Science and Religion material was prepared for presentation at our church, Christ the King Lutheran Church. I first attended the annual conference of IRAS in 1999, and my reflections are here. Some of my musings include short essays on the Enigma of Time, on Emergence, on The Future of Religion, a review of Douglas Hofstadter’s book I Am a Strange Loop, on intellectual solvent, and my wish for Gigaworld. Since I work a lot with computers, I sometimes think software makes us stupid. But I also find beauty in technical work, and when a friend who teaches Art Appreciation to college freshmen asked for ideas, I suggested a STEAM prize.

Since we use this as our home page, some of our favorite links include search engines Google, Yahoo, PubMed, maps at Google Maps, social networking on Facebook, dictionary Merriam-Webster, encyclopedia Wikipedia, the New York Times, and Arts & Letters Daily. Find shopping at Amazon, travel at Travelocity; and radio at NPR. As well, we have a separate page of favorites.
