I like the #flowers of this #plant but it is growing out of a gap in #concrete by the porch and garage. I think it must have propagated from a neighbour’s #garden many years ago. I tried to take a cutting and plant it in some soil in the back garden but it withered away. Evidently, it only likes rocky conditions. Can anybody tell me the species?
Our immediate neighbour, who moved in a year ago or so, keeps #bees. Sometimes, they swarm in our #garden. I don’t think there’s any danger but I think it’s wise to keep a safe distance from them. They eventually disperse on their daily foraging. Here, they’ve commandeered the #vine#plant.
Forgive the recent apparent obsession (I’d call it a fascination) with the #cycloid but I’ve just discovered something I’d not heard of before. It is also called a #TautochroneCurve or #Isochrone curve, which means that a particle starting from any location on the curve will get to the #MinimumPoint at precisely the same time as a particle starting at any other point.
After lunch yesterday, we went to the #HistoryOfScienceMuseum in #Oxford. It’s not very big but contains some really fascinating exhibits. It is right next to the #SheldonianTheatre and well worth a visit.
This wooden box contains some immaculate #brass#DrawingInstruments. Another rarity these days but I do remember learning how to use similar #instruments while studying at university.
Without anything but manual #SurveyingEquipment, humans were able accurately to map out the entire globe. It’s amazing what can be achieved when humanity works together. But also, this model is absolutely gorgeous.
No computers were around then but the ingenuity of humans to develop calculating instruments to allow them to crunch numbers meant the creation of some devices of stupendous cunning.
To this day, trainee pilots have to master the #CircularSlideRule in order to do calculations for various tasks. Before flying was ever developed, such #SlideRules were in common use.
Yesterday, we went on a day trip to #Oxford by #train. No other means of powered transport was used as we #cycled to and from our local #RailwayStation.
Here is the #countryside zooming past the train window.
Some of the centre is a zero-emission zone or #ZEZ, aimed at curbing the use of polluting vehicles. Such vehicle owners need to pay to use roads in that area.
