An illustration of the Weber–Fechner law. On each side, the lower square contains 10 more dots than the upper one. However the perception is different: On the left side, the difference between upper and lower square is clearly visible. On the right side, the two squares look almost the same.
Brown v. United States, 256 U.S. 335 (1921), was a United States Supreme Court case in which the Court held that if a person is attacked, and that person reasonably believes that he is in immediate danger of death or grievous bodily injury, he has no duty to retreat and may stand his ground and, if he kills his attacker, he has not exceeded the bounds of lawful self-defense.
Fig. 1: Fermat's principle in the case of refraction of light at a flat surface between (say) air and water. Given an object-point A in the air, and an observation point B in the water, the refraction point P is that which minimizes the time taken by the light to travel the path APB.
In the theory of probability for stochastic processes, the reflection principle for a Wiener process states that if the path of a Wiener process f(t) reaches a value f(s) = a at time t = s, then the subsequent path after time s has the same distribution as the reflection of the subsequent path about the value a. [1]
Therefore, the angle of reflection is the angle between the reflected ray and the normal and a collimated beam of light does not spread out after reflection from a plane mirror, except for diffraction effects. A plane mirror makes an image of objects in front of the mirror; these images appear to be behind the plane in which the mirror lies.
Reflection nebula are usually blue because the scattering is more efficient for blue light than red (this is the same scattering process that gives us blue skies and red sunsets). Reflection nebulae and emission nebulae are often seen together and are sometimes both referred to as diffuse nebulae. Some 500 reflection nebulae are known.
Orlistat (Xenical), the most commonly used medication to treat obesity and sibutramine (Meridia), a medication that was withdrawn due to cardiovascular side effects. Anti-obesity medication or weight loss medications are pharmacological agents that reduce or control excess body fat.
Glomerular capillaries have a reflection coefficient close to 1 as normally no protein crosses into the glomerular filtrate. In contrast, hepatic sinusoids have no reflection coefficient as they are fully permeable to protein. Hepatic interstitial fluid within the Space of Diss has the same colloid osmotic pressure as plasma and so hepatocyte ...
