A Picture from New Year's Eve
I am trying to learn about 3D shapes and finding it more difficult than I could have imagined. Starting on New Year's Eve, I've examined this cube from many angles in order to construct a mental 3D representation.
This picture is of me contemplating a black cube whose edges are outlined in Christmas lights. It is a cardboard box. Each dimension is a different length from the other two, and it is covered in black paper. Along every edge, at about one-inch intervals, is a hole with a light sticking out of it, so in a dark room I can only see the lit edges. For users of the vOICe, the cube is in the lower-left portion of the image. It is a little less than half the width of the image and a little more than half the height. I am on the far right side. The watch on my left arm, which is hanging down at my side, is at the bottom and the top of my head is at the top. My width is about forty percent of the right side of the picture. To me, the most noticeable things are the cube which I can recognize using zoom, the human-type shape which must be me, and the reflective watch near the right. There is also some stuff in the middle which is probably a table with papers on it. Thanks to Prof. Baldwin for cropping the picture and for his excellent descriptions. Also Thanks to Dave, the clever one who assembled the cube.
