Amwoga KhalwaleSimpson’s rule for approximating definite integrals was first published by Thomas Simpson in 1743. Although named after him, Thomas Simpson was not actually the one who first discovered it. Bonaventura Cavalieri discovered an early version of this rule in 1639 and James Gregory published this variation in1668along with some other numerical methods for approximating definite … Read more
The electromagnetic spectrum is the range of frequencies EM radiations along with their associated wavelengths and photon energies. It consists of Gamma-rays, X-rays, ultraviolet rays, infrared rays, radio waves and microwaves. Electromagnetic radiations have a wide range of frequencies, wavelengths and photon energy levels. These waves travel at the speed of light in vacuum. The … Read more
While Mennonites and the Amish come from the same Anabaptist roots that began in the 16th Century, the Amish became a separate group from Mennonites. In 1693, Swiss Anabaptist leader Jacob Ammann did not believe that banning and shunning was being practiced well enough. He felt the current church was not strict enough and he separated to create the Amish. … Read more
Almost all experimental studies are designed to include a control group and one or more experimental groups, each serving a different purpose. In most cases, participants are randomly assigned to either a control or experimental group. Experimental groups are usually manipulated to try and change the out come of the experiment. Control groups are usually … Read more
Cupcakes and muffins can look very similar but their characteristics can be pretty easily differentiated just by looking at them. The major difference lies in the way they are made, and their ingredients. They are also very different in their presentation and design. Although both emerged from the concept of “small cakes” or “individual cakes”, … Read more
Whole milk is a milk which contains all the components of milk eg water, fat, protein, lactose, minerals etc. Skimmed milk contains all the constituents except fat or negligible amount of fat. In other words, milk with its fat fully removed is called “skimmed milk”, “skim milk”, “fat-free milk”, or “nonfat milk”, depending on country. … Read more
What is Specific Heat? The specific heat of a substance also sometimes referred to as massic heat capacity is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg−1⋅K−1. Specific heat values can be determined … Read more
What is Specific Heat? Specific heat isthe quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree. For example, the specific heat of water is 1 calorie (or 4.186 joules) per gram … Read more
Vaporization and Evaporation which is a part of vaporization are the processes that are nothing but a phase transition of a substance from a solid or liquid state to gas. They are often used interchangeably but the two terms are quite different from each other. In this article, we provide a detailed overview of the … Read more
What is latent heat? The latent heat definition describes the amount of energy that is released or absorbed during a phase change at a constant temperature. A phase change is the change of a substance’s physical state from solid to liquid, liquid to gas, gas to solid, and so on. Matter can exist in three states including … Read more
