When a word is turned upside down, the top halves of the letters turn into the bottom halves. And because our eyes pay attention primarily to the top halves of letters when we read, that means that you can essentially chop off the top half of a word, turn it upside down, and glue it to itself to make an ambigram.
The nabla is a triangular symbol resembling an inverted Greek delta: [1] or ∇. The name comes, by reason of the symbol's shape, from the Hellenistic Greek word νάβλα for a Phoenician harp, [2] [3] and was suggested by the encyclopedist William Robertson Smith in an 1870 letter to Peter Guthrie Tait.
The nabla symbol, written as an upside-down triangle and pronounced "del", denotes the vector differential operator. When a coordinate system is used in which the basis vectors are not functions of position, the gradient is given by the vector [ a ] whose components are the partial derivatives of f {\displaystyle f} at p {\displaystyle p} .

Cut about a 2-inch segment from each pineapple slice and place the slices in 20 of the muffin cups. In the remaining 4 cups, use the 2-inch segments to create a ring. Add a cherry to the center of ...
