Thank you for coming by and commenting. I enjoy seeing you and your comments.
The garden is looking good and the weather has been cool and nice with much rain.
My best to you all.
The Mathematical Bridge is the popular name of a wooden footbridge in central Cambridge, bridging the River Cam, and connecting two parts of Queens' College. Its official name is the Wooden Bridge. Grade II listed.
Designed by William Etheridge and built by James Essex in 1749. It was rebuilt twice, in 1866 and 1905.
Although it appears arched, it's made entirely from straight timbers configured in tangent and radial trussing.

It barely got above freezing today and I was very pleased to see a Supralateral arc an Upper Tangent, Sundogs and a Sun Pillar all at the same time today :)) My dear friend Eileen sent me a diagram of all the proper names for these, it's fascinating and very pretty.

The Mathematical Bridge is the popular name of a wooden footbridge in the southwest of central Cambridge, England. It bridges the River Cam about one hundred feet northwest of Silver Street Bridge and connects two parts of Queens' College. Its official name is simply the Wooden Bridge or Queens' Bridge. It is a Grade II listed building.
The bridge was designed by William Etheridge and built by James Essex in 1749. It has been rebuilt on two occasions, in 1866 and in 1905, but has kept the same overall design. Although it appears to be an arch, it is composed entirely of straight timbers built to an unusually sophisticated engineering design, hence the name.
Mathematical explanation:
The arrangement of timbers is a series of tangents that describe the arc of the bridge, with radial members to tie the tangents together and triangulate the structure, making it rigid and self-supporting. This type of structure, technically tangent and radial trussing, is an efficient structural use of timber, and was also used for the timber supporting arches (centering) used for building stone bridges. Analysis of the design shows that the tangent members are almost entirely under compression, while the radial timbers are almost entirely subject to tension with very little bending stress, or to put it another way, the tangent and radial elements elegantly express the forces involved in arched construction.

Y cuando estás; arrullo de estrellas. Perfecto caos de torbellinos inmóviles. Tangentes que atrapan con su único punto en común. Superficies cambiantes en eterno baile arrítmico.
Pero si no estás; silencio ensordecedor. Preguntas en su eterna búsqueda de respuestas esquivas. Sortear esquirlas. Brillos metálicos que arañan al corazón.

The cathedral was shut being an afternoon in Spain and the square in front flooded with hundreds of cyclists, I'm not sure why, and photos seemed to be limited so I looked up for inspiration :)

A tangent universe pertains to an alternate time line that is created by an event occurring in an existing universe.

Please excuse my going off on a tangent, but this might be of interest to some people. As I was processing this picture I realized that what I was doing was equivalent to an informal mindfulness meditation practice Years ago I practiced meditation, but I quit after a few years; then in 2020 I listened to a couple of lecture series on Mindfulness, but I kept falling asleep when I tried to meditate.. I have recently listened to those lectures again and started meditating. As I was processing this picture I realized what I was doing was exactly what the lecturers describe as the objective of a mindfulness practice. In both formal and informal mindfulness the objective is to focus only on the present. Some tasks that are used for informal mindfulness meditation are eating, driving and walking. For example when I do my walking meditation I focus on my steps, which is easy as my walking shoes squeak badly. When I’m processing a picture I tend to hyper focus on what I’m doing to the exclusion of everything else. I lose track of time and completely ignore my surroundings; I will often miss a meal even though I can see the time on my computer. There is a great deal of research that shows that this type of activity is very beneficial to your mental wellbeing. I’m currently meditating 26 minutes five days a week and trying to work up to 45 minutes, but the quality of my meditation is not nearly as good as I get when processing a picture, although it is getting better. Perhaps I should just spend more time processing my pictures.
