Still struggling through cold weather... over here, we all dream about nice weather, warm and light... please?
I scoured woodlands and parks for any signs of spring and was hard pressed to find any. The fact is, I fear spring is a long way away yet. ;-/ The high here today was -3 C and it's supposed to snow this week.
Finally though, I started looking more closely at some of the trees. Aha! Signs of new growth.
I've been cooped up for a couple of days because of the weather so I was not in the mood to pose a bowl of apples this morning. I went out looking for some dried wild grapes but I think the sparrows and chickadees got there first. Enjoy your Flickr Friday and make a cool photo.

The Transamerica Pyramid in San Francisco. Built in 1972, William Pereria architect. 48 stories tall, 853 ft, 260m.
A sine bar consists of a hardened, precision ground body with two precision ground cylinders fixed at the ends. The distance between the centers of the cylinders is precisely controlled, and the top of the bar is parallel to a line through the centers of the two rollers. The dimension between the two rollers is chosen to be a whole number (for ease of later calculations) and forms the hypotenuse of a triangle when in use.
When a sine bar is placed on a level surface the top edge will be parallel to that surface. If one roller is raised by a known distance, usually using gauge blocks, then the top edge of the bar will be tilted by the same amount forming an angle that may be calculated by the application of the sine rule.
