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.
During the summer, you want the air blowing directly on you so you will feel cooler from the wind chill effect (which is how fans cool you off). So stand under the fan and turn it up on high speed. If you Do Not feel the air very well, then turn the fan off and flick the reverse toggle switch. Turn it back on high speed. If you feel more air, you have it in the right position. So whichever position you feel the most air movement when standing directly under the fan is the correct position for summer.
