While talking about egg sizes in the context of the Eggbot project, we realized that while we have access to a few samples, we do not have a good understanding of the normal variation in the sizes of various bird eggs.
The sizes of chicken eggs are well understood and well regulated, but for other types of bird eggs (like the emu egg above) the sizes are not necessarily so standard. If you have access to other types of eggs or eggshells, we’d like your help in gathering data about the size and variation in these other types of eggs.
We’ve set up a survey form to collect egg size data and we plan to post about our results once we have collected enough data.
While walking through Home Depot on an unrelated mission, we happened to walk by a display of succulents, and were struck by the unusual blue color of some of the flowering cacti.
But on closer inspection, we could see what was really going on: the flowers on the top were attached… with glue. In fact, most of the flowers on the cacti and succulents were glued on. Some of them, like this winner here, even had globs of glue spilled down onto the spines of the cactus below.
This is a deceptive (yet sadly common) practice— and apparently many people do get fooled by it —as we found garden forum posts and warning articles about it, including here, here, here and here. This seems not so far away from buying a fruit tree at a nursery, only to find out (once you get it home) that the fruit was only glued to the tree.
It looks like they are trying to make the less showy cactuses compete with the brightly colored grafted ones that they sell, like the ones shown pictured here. (This may not be a naturally occurring configuration, but at least it is a real, living plant.)
Strawflowers are used because they keep their color well after drying. They also open and close as the humidity changes and they absorb more water or dry out more, giving the illusion of being part of a living plant.
And if it’s not bad enough that the customer is being deceived about the nature of plant they are buying, the glue can often damage the plant below, especially during the removal process.
Adrift is a beautiful short film by Simon Christen chronicling the fog of the San Francisco bay.
I spent many mornings hiking in the dark to only find that the fog was too high, too low, or already gone by the time I got there. Luckily, once in a while the conditions would be perfect and I was able to capture something really special. Adrift is a collection of my favorite shots from these excursions into the ridges of the Marin Headlands.
Fitzgerald Marine Reserve is a protected marine and intertidal park located at Moss Beach, California, about 40 minutes south of San Francisco, just north of Half Moon bay. It’s a spectacular place to visit at low tide, for some of the finest, most accessible tide pools in the region.
And as you’ll see, there’s definitely a lot to look at.
Fern Canyon is a lush little feature of Prairie Creek Redwoods State Park— a tiny winding canyon whose dripping walls are lined with soft ferns and vibrant mosses.
The park is located very northwest corner of California, nestled against Redwood National Park. The two parks are managed together, as part of the “Redwood National and State Parks.” It’s a substantial six hour drive north from San Francisco or Silicon Valley, but as you will see, it’s unique, and arguably worth the trip.
