My sister Carol brought her three grandsons over for a visit today. Drake, the newest, watches what the older boys are doing.
Later, my Mom and Dad made a surprise visit. What a nice family visit day!

Fire Tulips
I planted some bulbs in the patio in December and these unusual tulips are now showing their beautiful fiery colors.
Los Angeles Breakwater
This is the view looking east from Land’s End at the southernmost end of Pacific Avenue in San Pedro. In the distance, tall thunderclouds can be seen over the Santa Ana Mountains. Verna snapped this and I cropped it into a panoramic view of the scene. Click on the picture for the full-sized panorama.
Choppy Seas
We took a drive today down to the south side of the Palos Verdes Peninsula. Verna took a lot of pictures and I took a few, including this panoramic seascape. Catalina island can be perceived through the sea mist kicked up by blustery winds. Click the image for the full panoramic view.
Happy PI Day
During my career in aerospace and also as a pilot and flight instructor, I have been using the quantity PI (approximately equal to 3.14159265). As explained in the article excerpt below, PI is the ratio of the circumference of a circle to its diameter. Also in the article below is the notion that you can approximate the value of PI by throwing needles or frozen hot dogs.

HAPPY PI DAY: March 14th (3.14) is PI day and all around the world mathematicians are celebrating this compelling and mysterious constant of Nature. PI appears in equations describing the orbits of planets, the colors of auroras, the structure of DNA. It’s everywhere.
Humans have been struggling to calculate PI for thousands of years. Divide the circumference of a circle by its diameter; the ratio is PI. Sounds simple, but the devil is in the digits. While the value of PI is finite (a smidgen more than 3), the decimal number is infinitely long:

81640628620899862803482534211706…moreSupercomputers have succeeded in calculating PI to more than 200 billion digits and they’re still crunching. The weirdest way to compute PI: throw needles at a table or frozen hot dogs on the floor. Party time!
I wrote a universal triangle calculator using PI and other constants.
