    I'm still not convinced that is what it is. Can't find the weight of novaculite, except in shipping charges. Could only find specific gravity.

    Specific gravity
    Novaculite 2.5
    Iron 7.0

    Doesn't that mean it is not as heavy as iron, per cubic inch? This thing is definitely as heavy as iron. Physics was never my strong subject. :p

    Steel honing plate. I'll put it in water and see if it rusts. :D

    Bronze "whetstone" in the form of a stag, ca. early 1st millennium B.C.

    @Nancy Hart
    If you are able to casually talk about Specific Gravity, you are likely ahead of many. Personally, I've always liked "Density" better, same concept, S.G. usually applying to liquids, density easier for me to understand. Here's a trivia "quirker": In the Chemical Elements, the higher the number, the greater number of particles contained. Thus the least, like Hydrogen, Atomic No.1 and Helium, At. No. 2, are gasses. Higher up, they become metal-like, Aluminum #13, for example. So, Uranium, #92, would be expected logically to be the heaviest element, no?

    No. Heaviest is Osmium, #76, far below Uranium 92 in #. Actual density depends on the packing of the atoms in their crystal-lattice.

    @Frank Sanoica : .Just saying "specific gravity is 2.5" is pretty casual talk alright. LOL

    Bottom line though, doesn't it mean if I held a 4.5" x 2" x 1" piece of iron in one hand, and the same size Novaculite in the other, the iron would feel a lot heavier?

    Thank you Joe, but this raises another question.

    WHY does the weight scale go up by the weight of the water displaced?

    Why does the scale think there is more water in there? ( Never mind... I'm over-thinking. :rolleyes: )

    Did NOT like basic physics at all. :p

    The weight scale goes up when the rock is NOT suspended by the string, but is instead resting on the bottom of the container.

    That part makes sense. The scale is adding together the weight of the rock and the water.

    But the weight scale goes up when the rock is suspended also.

    Never mind, really. I'm just dense tonight (no pun intended). ;)

    Tuesday is trash and recycling pick up day here in town.

    How in the world can just one person and a cat produce so much trash? There are very few food scraps, because I rarely cook from scratch. The vast majority consists of packaging materials. I wish all that packaging weren't necessary.

    The house where I grew up sat on approx 2 acres of land. It was on the dividing band between suburbs and farm land, at least at first.

    I was the designated garbage disperser. There would always be a pan filled with food scraps. My job was to take it down in the back field and hurl it, to spread it out as thinly as possible. It just disappeared. I suppose animals ate it. I still remember what that pan looked like. :p

    We had a burn barrel for other trash --- a 55 gallon drum for stuff that would burn.

    My father was the caretaker of that. I guess metal cans went into the burn barrel. There probably weren't many, because my mother always canned a lot of things in jars.

    Even way out in the country many have private garbage and recycling service now. I've always just brought all the trash from out there in town. And the lawn clipping from town go out in the country. Quite a pile of red tip cuttings have built up out there now. I should disperse them more.

    When I was a kid, where I grew up, we had a town dump, but I think it was fairly new. Most families were farms and they had their own dumping areas. Ours was on the other side of our pasture. That was where the trash that couldn't be fed to animals, composted, or burned was dumped. My brother has a very nice home and yard on the site of our former family dump right now, while the pasture has grown into woodlands. I had to mention the woodlands, given that this thread is about trees and other things.

    I'm not sentimentally attached to the title of this thread. It's just a journal, and I knew the subject of trees would come up more often than anything else. It's a constant battle against dead and uprooted trees here.

    Why... would they do this? They must not have internet access. :rolleyes:
