If you mean in the sense of the novel "The Invisible Man", no, invisibility is not possible. However, many magicians have perfected hundreds of magic tricks that give the illusion of things being invisible or appearing from nowhere. I suggest you get some books from the library about famous magic illusions. I am not aware of anything in the world of science that is invisible, except for maybe invisible ink, invisible mending systems, and stuff like that. Also, there is the radar invisibility of such things as stealth bombers and fighter jets.
