The Sun's Progress

[Deleted]

Yesterday morning - first 2 pics are as I noticed the sunlight - from ground floor, for the 3rd I went up to landing window so the beech in the hedge on the left of the pic can be seen

I used to enjoy watching the change around 21st, if lucky enough to have a few sunny spells I would mark the shadow from the top edge of the window on the opposing wall (with pencil) - before and after the 21st so you could see that slight increase in height even by just after Christmas.
An interesting thing was that leaving the marks there over a few years the exact position varied year to year more than you'd think.
I used to do make a mark at exactly 1pm when usually in for dinner.

That's a pretty poor explanation. The trouble with mine is that it's short, but only understandable by someone with post A level maths.
Hilbert's relationships show you cant change the amplitude of an oscillatory system without changing its phase.

Did that help?

Well, that has cleared it up for me....
