Frames of Reference
A n amazing thing happened recently: A nonengineering person publicly praised what our profession has accomplished. Marilyn vos Savant writes a weekly column for Parade magazine, part of the Sunday newspaper for many people in the US. Vos Savant reportedly has the highest IQ ever recorded. Even if you believe that IQs don't mean much, vos Savant corroborated her brilliance when she stated in he...
متن کاملInner space: Reference frames
How are we aware of our surroundings? Somehow, from a pair of tiny, two-dimensional pictures of the visual world – provided by our retinas – our brains are able to render the world as it is, accurately depicting the locations of both a distant mountain range and the camera we are pointing at it. To understand how space is represented in the brain, neurophysiologists have borrowed the useful con...
متن کاملReference Frames for Animate Vision
Animate vision systems have gaze control mechanisms that can actively position the camera coordinate system in respose to physical stimuli. Compared to passive systems, animate systems show that visual computation can be vastly less expensive when considered in the larger context of behavior. We are accustomed to thinking of the task of vision as being the construction of a detailed representat...
متن کاملCovariance and Frames of Reference
A transition of focus from state space to frames of reference and their transformations is argued as being the appropriate setup for ensuring the covariance of physical laws. Such an approach can not only simplify and clarify aspects of General Relativity, but can possibly help in the development of a Grand Unified Theory as well. " Physics may be not only too important, but also too deep, in o...
متن کاملReference Frames for Stellar Aberration
There is some confusion in the literature as to what velocity should appear in the stellar aberration formula. Because the aberration formula is usually derived from the same equations as the Doppler shift, where the relative velocity between source and detector is the relevant one, it is often assumed the same holds for aberration. This is not the case. Authors who choose the orbital velocity ...
