In philosophy, the term idea has been used to cover a range of concepts. Ideas are often construed as mental representational images; i.e., images of some object. In other contexts, ideas are taken to be concepts, although abstract concepts do not necessarily appear as images.
If you have ceiling fans, they can help you maximize your air conditioning by lowering the temperature. However, that will only work if you have the fan going in the right direction. In the summer, you want the fan to go in a counterclockwise direction, also known as the forward direction. This helps drive air down toward the room's occupants. As the moving air hits the skin, it causes it to feel cooler than it really is.
In the summer, the preferred direction for a ceiling fan to spin in is a counterclockwise direction as you look up at the fan blades. You will feel a cool downward airflow as you stand directly under the fan. In the winter, the preferred direction for a ceiling fan to spin in is a clockwise direction.
