gottawonderToday I am grateful for:
Another cooler day. It oddly feels like autumn.
The farrier was supposed to come today, but had to reschedule for tomorrow. I really hope she makes it, because Wonder's feet are chipping.
I worked at stuff today, but none of it felt like I got "finished" anything. I took two wheel barrows of manure out of the goat/pony pen.
I took some dirt from the pile beside the house over to a spot in the yard that is low.
I pulled weeds from a different spot beside the house, and took dirt from one spot that was too high, and used it to fill in a hole beside the house that my husband was leaving open to access wires that can be filled for now.
I let everyone out for a while, and mowed. First, I had to get a yard cart and pick up rocks all along the edge of where we park the cars. My husband at one point, thought it would be a brilliant idea to put big rocks all along this area, so we wouldn't drive on the grass. Well, it's not that hard to figure out where the grass is, and all that happened is that I couldn't mow the edge of the driveway, and then the grass right there grew about waist high, and it's a pain in the ass to weed-whack it. So, I pulled out all the rocks and put them into a cart, and then I could finally mow the edge of the driveway.
I only mowed about 1/4 of the yard, but hey, it's better than nothing.
Talking to my Sweetie; he and his parents paid their respects at the cemetery today.
I learned that sound travels faster through materials that are less elastic. Slowest through normal air, faster through water, and very fast through a rigid material because there is less movement (think of sound moving as a wave, and being able to move in a much straighter line through a solid).
"sound travels at 343 m/s in air, it travels at 1,481 m/s in water (almost 4.3 times as fast) and at 5,120 m/s in iron (almost 15 times as fast). In an exceptionally stiff material such as diamond, sound travels at 12,000 metres per second (39,000 ft/s),[2]— about 35 times its speed in air and about the fastest it can travel under normal conditions."
When we hear about a plane travelling at Mach 1, that is actually the speed of sound as it travels through air. Mach 2 is twice the speed of sound travelling through air.
Personal thought: It is interesting to think about how sound might move through very fast through a metal cymbal, and it would slow down in air.
