Art
Art is a diverse range of human activities in creating visual, auditory or performing artifacts (artworks), expressing the author's imaginative or technical skill, intended to be appreciated for their beauty or emotional power. In their most general form these activities include the production of works of art, the criticism of art, the study of the history of art, and the aesthetic dissemination of art.
Design
Design is the creation of a plan or convention for the construction of an object, system or measurable human interaction (as in architectural blueprints, engineering drawings, business processes, circuit diagrams, and sewing patterns). Design has different connotations in different fields (see design disciplines below). In some cases, the direct construction of an object (as in pottery, engineering, management, coding, and graphic design) is also considered to use design thinking.
Photography
Photography is the science, art, application and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film.
Design
Good design is a Renaissance attitude that combines technology, cognitive science, human need and beauty to produce something.

Art
I remember some artists who said this world isn't worth anything, that it is a pigsty, that we are going nowhere, that God is dead, and all those things. Bad literature is this. To expose your navel, to tell how you drank your morning coffee amid general disgust, with everything around you rotting. While the world is dying, I drink my coffee. Or I perform my little sex acts. This is old-fashioned. One must cross this neurotic curtain.

Design
Good design is also an act of communication between the designer and the user, except that all the communication has to come about by the appearance of the device itself. The device must explain itself.
