    Richard Feynman: Revolutionizing 20th Century Physics

    In reading or listening to anything on 20th century physics, Richard Feynman and his physics play a prominent role. With this in mind, I listened to Genius: The Life and Science of Richard Feynman. When we think of scientific genius in the 20th century, Richard Feynman stands out not just for his intellect but for…

    Exploring Chaos Theory: From Niagara Falls to Science

    My wife and I recently took a trip to Niagara Falls, staying on the Canadian side. I also just finished reading Chaos: Making a New Science, by James Gleick. As I looked at the falls and the rushing Niagara River, thinking about all of that turbulence enhanced the experience. James Gleick’s Chaos: Making a New…

    Observing Dryad’s Saddle: The Forest’s Spotted Surprise

    You can see my observation on the iNaturalist site here. A Welcome Sight in Spring Today’s woodland walk brought a delightful surprise: a beautiful cluster of Dryad’s Saddle mushrooms, also known as Polyporus squamosus. This impressive bracket fungus often appears on dead or dying hardwood trees—particularly elm, maple, or box elder—and is a welcome herald…

    Derek’s Stuff

    I have mentioned Derek in an earlier post about my cherry/purpleheart dining room table. In this short clip from his most recent YouTube video, you see his stone kitchen sink. I have been impressed by Derek’s metalworking and blacksmithing, and am amazed by his stoneworking skills. You can see more of his work on his…

    Exploring the Evolution of Information in James Gleick’s Work

    I have found “information” fascinating. It seems to tie everything together. That is what attracted me to The Information.

    🌿 Hyssop: The Sacred Herb with Healing Power

    A few years back, I enjoyed making mead. My son, who also makes mead, suggested using hyssop in my mead. I also noticed at the store of a Bucks County PA distillery, hyssop-infused bourbon. I tried unsuccessfully for a few years to grow it, but last year I finally got it to grow. I did…

    The Philosophy of The One-Straw Revolution

    When we sold our Pennsylvania house, we had to install a new septic system as a condition of the sale. The only place on the property that suited the installation was at the location of my garden, so the garden had to be destroyed. I had gardened for 16 years using permaculture principles. No chemical…

    Slow-Carb Diet: Make Your Own Vinaigrette

    I generally follow the slow-carb diet as prescribed by Tim Ferriss in The 4-hour Body. When using salad dressings, I try to use no sugar varieties, and especially with no sugar added. These have been almost exclusively store-bought and almost always use seed oils. To avoid these, I thought I would start making my own,…

    Masanobu Fukuoka’s Guide to Sustainable Gardening

    Yesterday spent time in the annual garden putting in plants purchased from a local garden center. It is the time of year to think about the garden, and nature. That brings to mind the One-Straw Revolution.

    Resolving AI Download Errors on Windows and Ubuntu

    As I have blogged in the past, I work with AI for my various activities, including my book summaries. I ask the AI for the book analyses in various files to download. In my last effort, when I went to download the files, I got an error message “File not found”. Working with AI found…
