I try to focus, really I do, but things keep changing

If he were still alive, today would be my grandfather Nathan Silberman's 146th birthday. Unfortunately, he left us just over 50 years ago in December 1970, three months before what would have been his 96th birthday.

All through his life my grandfather said he was born on the first day of Spring. I cannot remember when the vernal equinox somehow stopped occurring on March 21st and started occurring on March 20th, but I read this week that because of time zone differences between North America and the place our days begin (the International Date Line in the middle of the Pacific Ocean), Spring would not begin on March 21st in North America at all during the remainder of this century.

Grandpa would be so disappointed.

In Charlestonese, the type of English spoken in parts of coastal South Carolina, people say that buds wobble in the sprang (translation: birds warble in the Spring). Well, buds ain't the only thang that wobbles.

Did you know that Earth's axis also wobbles like a top? Well, it does. The North Pole won't always point to Polaris. The wobble takes something like 26,000 years to complete one circuit. It's called 'axial precession' and you can read all about it 'rat cheer' (translation: right here).

In other news, the answer nobody on Jeopardy! knew on Friday evening was "What is a hunter?". The category was Biblical Occupations and the clue mentioned the book of Genesis and Nimrod. At least someone knew that the answer to "_________ were abiding in the field keeping watch on the night Jesus was born" was "What are shepherds?" and the clue didn't even include "over their flocks".

Until next time, T.T.F.N.
