    Nicolas Poussin - The Rape of the Sabine Women In The Rape of the Sabine Women‚ there is no obvious vanishing point.

    Considering this‚ full frame lenses have a bigger image circle than the image circle on crop lenses. This is the key difference between these two lens types and we have seen this in the many examples of cropped vs full frame. As I said earlier‚ full frame lenses have no problem adjusting to cropped sensors because the image circle is big anyway. On the other hand‚ if you were to put a cropped lens on a full frame sensor the image circle would be too small to cover the entire sensor and‚ as a result

The bold diagonal lines make the entire piece very dynamic and really invokes the sense of movement in the directional lines as Kat chases the rock down the hill. Since the cartoon focuses more on the simple outlines of the characters‚ the lines used to indicate movement‚ as well as the crosshatching shading style both bring out the contrast of the piece

    Chapter 13 – States of Matter Pressure (P) – the amount of force per unit area. Pressure=F/a  or  P=F/a Pascal’s Principle “Any change in pressure at a point on a confined fluid is transmitted throughout the fluid”.  Any change is transmitted throughout the fluid. Buoyancy & Archimedes Principle “When an object is submerged in a fluid‚ it displaces a certain volume of that fluid.  The amount of force pushing upward on the object is equal to the density of the fluid (ρ) times the acceleration

    Cyclic dienes added to alkene dienophiles also lead to two new form of stereoisomeric products‚ the endo and exo products (Kilway‚ “Lecture”). In cases where dienes and dienophiles align above one another‚ the endo product is formed (Hunt). The endo product will have two axial substituent groups (Kilway‚ “Lecture”). This formation typically forms the major product because it takes less kinetic energy to be formed due to secondary orbital interactions with the substituents in transition states (Hunt)

    Do you ever feel like someone is watching you when you walk past a mirror? That’s because we are always watching you. I’ve been hanging on the wall at the Capulet house for more than 15 years.

    Refractive Index: Refractive Index formula is use to find the change of speed of light as it travels from air into glass. It measure how much light slows down when it enters denser medium such as glass. The formulae is written as: To find out the refractive index‚ substitute these into the equation; The speed of light travels in air is 3 x 10^8-1 The speed of light travels in glass is 2 x 10^8 ms^-1 Refractive Index (Glass): 3 x 10^8 / 2 x 10^8 = 1.5 When light enters glass‚ its reflective index
