AI Thread Summary
A dimension can exist that is neither temporal nor spatial, as evidenced by concepts like "state space," which encompasses various characteristics such as speed and temperature. The dimensions in this context are defined by the minimum independent coordinates required to specify a point in that space. This allows for the inclusion of non-traditional dimensions, such as reaction or acceleration, which reflect interactions between entities. The discussion emphasizes that movement and reactions extend beyond just time and space. Thus, the exploration of dimensions can include a broader range of characteristics.

Is it possible?
 
Physics news on Phys.org
Yes, and there are many instances. A system is often described as moving in a "state space". That ascribes dimensions to all sorts of characteristics, such as speed, potential energy, temperature... whatever you like.
 
The number of dimensions used to describe spaces is the minimum number of independent co-ordinates needed to specify a point in that space. The co-ordinates may be any units you choose.
 
Could reaction (aka acceleration) be considered to be a dimension. Things don't just move through time and space; they also react to each other?
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
