Bright, colored areas of light beside the Sun are known as sun dogs (sometimes written as one word: sundogs). They’re often approximately 22 degrees to the left or the right (or both!) and about the same distance above the Horizon as the Sun. They’re also often seen as part of a ring or Halo around the Sun. Sun dogs form when there are hexagonal ice… Read more →
A Strobe is a light or lamp that flashes regularly and can make moving objects look like they’re not moving or like they’re moving very slowly. If the object you’re looking at using a Strobe is moving at the same frequency as the Strobe is flashing, the object appears completely motionless. The Stroboscopic Effect is a visual phenomenon caused by aliasing that occurs when continuous motion is represented… Read more →
A carbon footprint is defined as: The total amount of greenhouse gases produced to, directly and indirectly, support human activities, usually expressed in equivalent tons of carbon dioxide (CO2). Typically, a carbon footprint is calculated by estimating not just the CO2 emissions that the activity in question causes, but also any emissions of other greenhouse gases (such as methane and nitrous oxide)… Read more →
Ripening is a process in fruits that causes them to become more palatable. In general, the fruit becomes sweeter, less green (typically “redder”), and softer as it ripens. Ripening agents accelerate ripening. An important ripening agent is an ethylene, a gaseous hormone produced by many plants. Many synthetic analogues of ethylene are available They allow many fruits to be picked prior to full ripening, which… Read more →
Soundproof glass works by creating a near-impenetrable barrier between the sound and your ears. It takes on the mechanical energy of the sound wave and captures it. Such material can block between 90 to 95% of most sounds, with only a few frequencies as an exception. To block any noise, you need to fulfill five principles of soundproofing. These are:… Read more →
Hot air is less dense than cold air. When you light a candle, the air near the wick gets hotter and ( being less dense) gets pushed up by heavier and denser cold air(being heaver cold air is pulled down to earth). Flame of a candle is actually burning wax vapors. When the hot air rises, wax vapors also rises(because… Read more →
Seismometer A seismometer is a device that is sensitive to vibrations. It works on the principle of a pendulum: a heavy, inert mass with a certain resistance to movement (i.e. inertia) due to its weight is suspended from a frame by a spring that allows movement. The energy from any seismic activity excites this “proof mass” as it is called… Read more →
The sites are not only accessible through Google. Currently, it’s just a very small part of the internet. However, the Web can be divided into three main components, namely the Surface Web, the Deep Web and the Dark Web. Most people believe the web is the Surface Web. Particularly in online content, search engines or links can be easily accessed.… Read more →
