Humans perform perceptual categorization through the processes of visual recognition and attentional selection \cite{tva}. A perceptual categorization has the form ``$x$ belongs to $i$" (denoted by $ E(x‚i) $‚ $ E(x‚i) \in [0‚1] $ )‚ where $x$ is an input element in the visual field to be categorized (called \textit{perceptual units}) and $ i $ is a \textit{perceptual category}. The collection of all perceptual units is denoted by $ S $ and the collection of all categories is denoted by $ R $

Law of Refraction- by Aydar Z. Hypothesis: During investigation‚ student will calculate 2 sets of Angles of Incidence & Refraction. The Hypothesis is that 2 outer angles would have very similar values (1st angle of Incidence and 2nd angle of Refraction)‚ while 2 inner angles will also have similar values (2nd angle of Incidence and 1st angle of Refraction). This Hypothesis is based on earlier test investigations where outer angles were very similar in a range of 3 degrees and inner angles were very
