The end of the day at Grand Haven Llighthouse.

Apologies to my arachnophobia friends!

Lacking a drone, the best way to get a shot like this is to stand atop a ruined 15th Century castle, as I did. Seen from Easkey Castle, Co. Sligo, Ireland.

By the way, 'angular momentum' has nothing whatsoever to do with this image, other than it sounded like a cool title.

This is my grandfather's stopwatch.

Each clock hand has a different angular velocity.

The seconds hand, perform one revolution every 1 minute: FAST;

The minutes hand, perform one revolution every 60 minutes: MEDIUM;

The hours hand, perform one revolution every 720 minutes: SLOW.

Prise lors d'une Balade Parisienne à la Défense il y a quelques dimanches froids ...

I found this odd-shaped little spider guarding her egg sac which is carefully wrapped in a leaf. Tmarus Genus (a type of crab spider). She looks similar to this Tmarus angulatus on bugguide: bugguide.net/node/view/261562/bgpage

Found in a field down the street in Cedar Rapids, Iowa.

Id corrections appreciated.

My #35 spider for this year.

Angular momentum is a fundamentally important concept in quantum mechanics, even more so than in classical mechanics. This photo is of a book on the subject.
