Modern humans are the products of a sprawling history of shifts and dispersals, separations and reunions — a history characterized by far more diversity, movement and mixture than seemed imaginable a mere decade ago.

helicopters feature spinning wings called blades or rotors on top. As a helicopter's blades spin, they create a force called lift that allows the helicopter to rise into the air.The rear rotor can face different directions, allowing the helicopter to move forward, backward, and sideways

The invention of the Atomic bomb Robert Oppenheimer, known as the "father of Atomic bomb," performed a trinity test on 6th July 1945 in a desert location close to Alamogordo, New Mexico. It was the first time when the atomic bomb was victoriously exploded.

Normal body temperature ranges from 97.5°F to 98.9°F (36.4°C to 37.2°C). It tends to be lower in the morning and higher in the evening. Most healthcare providers consider a fever to be 100.4°F (38°C) or higher.

A normal heart's bpm is thought to be 60-100, but experts are increasingly suggesting the ideal heart rate is 50-70 for the general populace

I have introduced the concept of asymptotic freedom in QCD.

The situation is opposite in QED. The intuitive picture is as follows:

At large distance, vacuum polarisation causes the appearance of virtual charged particles that tend to screen out the electric field of a supposedly point charged particle, like the electron. Thus, the large distance coupling constant is lower and the effective electric field from the charged particle becomes weaker.

At short distance, the screening effect becomes insignificant and the reverse happens.

Vitamin D helps regulate the amount of calcium and phosphate in the body. These nutrients are needed to keep bones, teeth and muscles healthy. A lack of vitamin D can lead to bone deformities such as rickets in children, and bone pain caused by a condition called osteomalacia in adults.

Our body creates vitamin D from direct sunlight on our skin when we're outdoors. From about late March/early April to the end of September, most people should be able to get all the vitamin D we need from sunlight.

Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species (the reducing agent) undergoing oxidation (losing electrons) while another species (the oxidizing agent) undergoes reduction (gains electrons)

Chocolate is especially rich in flavanols like epicatechin and catechin, as well as anthocyanins and phenolic acids. All of these compounds help protect your cells from inflammation, improve your brain function, and boost your immune and cardiovascular health. Dark chocolate can also give you: Cardiovascular support.

the biggest computer virus ever is the Mydoom virus, which did an estimated $38 billion in damages in 2004. Other notables are the Sobig worm at $30 billion and the Klez worm at $19.8 billion.

The ant is one of the world's strongest creatures in relation to its size. A single ant can carry 50 times its own bodyweight, and they'll even work together to move bigger objects as a group! Ants carry leaves and twigs back to their nests!

genetically modified organisms can be defined as organisms (i.e. plants, animals or microorganisms) in which the genetic material (DNA) has been altered in a way that does not occur naturally by mating and/or natural recombination.

Neurons are cells that send and receive electro-chemical signals to and from the brain and nervous system. There are about 100 billion neurons in the brain. There are many more glial cells; they provide support functions for the neurons, and are far more numerous than neurons. There are many type of neurons.

An adrenaline rush is sometimes described as a boost of energy . Other symptoms include: rapid heart rate. sweating. heightened senses. rapid breathing. decreased ability to feel pain. increased strength and performance. Adrenaline rush will usually have an underlying cause, such as stress or a tumor on the adrenal glands. People should consider seeing a doctor if they are experiencing frequent adrenaline rushes, as these can have an impact on health in the long term.

The human body is approximately 99% comprised of just six elements: Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus

Nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay

There are about 1,500 potentially active volcanoes worldwide, aside from the continuous belts of volcanoes on the ocean floor at spreading centers like the Mid-Atlantic Ridge. About 500 of those 1,500 volcanoes have erupted in historical time.

 All the different parts of your eyes work together to help you see. First, light passes through the cornea (the clear front layer of the eye). The cornea is shaped like a dome and bends light to help the eye focus. Some of this light enters the eye through an opening called the pupil

A reagent is a substance or compound added to a system to cause a chemical reaction, or added to test if a reaction occurs. The terms reactant and reagent are often used interchangeably—however, a reactant is more specifically a substance consumed in the course of a chemical reaction. Solvents, though involved in the reaction mechanism, are usually not called reactants.

to convert number in parts-per million (ppm) to percent (%). 1% = 1/100. 1ppm = 1/1000000. So one parts-per million is equal to 0.0001 percent: 1ppm = 0.0001%. So to convert from ppm to percent, divide the ppm by 10000: x (%) = x (ppm) / 10000.

The 4 types of alcohol are isopropyl alcohol, methyl alcohol, undistilled ethanol, and distilled ethanol. Alcohol is the primary active ingredient in some of the most popular drinks on the planet. Beer, wine, spirits, and liquors all contain varying amounts of alcohol.

Ghosts are virtual particles introduced to a non-Abelian quantum gauge theory to eliminate unphysical gauge freedoms in order to preserve unitarity (probability conservation).

This technique is not strictly needed to describe photons in QED, since a simple condition (Gupta-Bleuler condition) is sufficient to eliminate longitudinal and time-like polarizations.

The fundamental unit of matter is composed of particles called atoms which are tiniest and indivisible. Since, atoms can neither be created nor destroyed, mass which is made up of atoms also cannot be destroyed or created. So, mass remains conserved and the law that defines about mass conservation is called law of conservation of mass.
