In 1954 George Devol invented the first digitally operated and a programmable robot called the Unimate. In 1956, Devol and his partner Joseph Engelberger formed the world's first robot company. In 1961, the first industrial robot

Turing machines, first described by Alan Turing in Turing 1936–7, are simple abstract computational devices intended to help investigate the extent and limitations of what can be computed. Turing's 'automatic machines', as he termed them in 1936, were specifically devised for the computing of real numbers.

The air in the exosphere is very thin, and is made up mostly of helium, and hydrogen. Traces of other gases such as atomic oxygen and carbon dioxide can also be found. The upper level of the exosphere is the farthest point from earth that is still affected by earth's gravity.

The history of technology begins even before the beginning of our own species. Sharp flakes of stone used as knives and larger unshaped stones used as hammers and anvils have been uncovered at Lake Turkana in Kenya.

Cross section (denoted by sigma) measures the number of scattered events in 2-particle collisions.

Differential cross section is given by the formula below, (here M is the invariant amplitude of a specified quantum process).

A series can be represented in a compact form, called summation or sigma notation. The Greek capital letter, ∑

∑ , is used to represent the sum.

The series 4+8+12+16+20+24

4+8+12+16+20+24 can be expressed as ∑n=164n . The expression is read as the sum of 4n as n goes from 1 to 6 . The variable n is called the index of summation

To generate the terms of a series given in sigma notation, successively replace the index of summation with consecutive integers from the first value to the last value of the index.

To generate the terms of the series given in sigma notation above, replace n by 1,2,3,4,5,  and  6

Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. 

The main function of the mesosphere is forming turbulences and atmospheric waves that act at spatial and temporal scales of enormous size. This is the region in which spacecraft returning to Earth after a voyage, begin to observe the structures of the winds in the background.

Feynman diagrams are pictorial depiction of quantum interactions between particles. Each diagram corresponds to a probability amplitude of a given event depicted in the diagram.

A neat fact is that mathematically, a particle moving forward in time (with 4 momentum p) is identical to the corresponding anti-particle moving backwards in time (with 4 momentum -p). Both Figure 8.9 and 8.10 depict the same scattering event.

P.S: Of course, you should not interpret backward-moving particles too literally. It is just a mathematical trick after all.

The most common cause of trisomy is a problem in the duplication of chromosomes to create egg and sperm cells. Somewhere along the way, a chromosome duplicates itself twice, creating a full pair. When the egg or sperm cell joins with its counterpart, the extra chromosome is taken along, creating a set of three where where should be two.

The pedosphere (from Greek πέδον pedon "ground" or "earth" and σφαῖρα sphaira "sphere") is the outermost layer of the Earth that is composed of soil and subject to soil formation processes. It exists at the interface of the lithosphere, atmosphere, hydrosphere and biosphere. 

 alcohol is an organic compound that carries at least one hydroxyl functional group (−OH) bound to a saturated carbon atom. The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks

For a long period of time, nature has been thought to observe the CP symmetry. C is short for "charge conjugation" and represents a flip in charge and P stands for "parity inversion" and represents a flip in spatial coordinates.

As a result of the postulated CP symmetry, both particles and anti-particles would obey the same physics.

However, the observed decay of neutral kaons proved that CP is not conserved in all processes.

There are several known sources of CP violation in the Standard Model. None of them can account for the relatively large asymmetry between matter and anti-matter in the early universe. (Matter would not have existed if both matter and anti-matter were present in equal amounts)

Each fertilizer contains trace amounts of secondary nutrients or natural elements necessary to organic growth. These elements are calcium, magnesium and sulfur and small amounts of copper, iron, boron, zinc, chlorine, manganese and molybdenum. These elements are found in all organic material.

The mole (symbol: mol) is the base unit of amount of substance in the International System of Units (SI). It is defined as exactly 6.02214076×1023 particles, which may be atoms, molecules, ions, or electrons.The mole may also be used to measure the amount of atoms, ions, electrons, or other entities.

Kepler's first law - a law stating that the orbit of each planet is an ellipse with the sun at one focus of the ellipse.

Pure water has a pH of 7, and, generally, rainfall is somewhat on the acidic side (a bit less than 6). But, acid rain can have a pH of about 5.0-5.5, and can even be in the 4 range in the northeastern United States, where there are a lot of industries and cars.

Taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world

Phosphorus is a mineral found in your bones. Along with calcium, phosphorus is needed to build strong healthy bones, as well as, keeping other parts of your body healthy

have you talked about how raccoons can purr?

An artificial island or man-made island is an island that has been constructed by people rather than formed by natural means. Artificial islands may vary in size from small islets reclaimed solely to support a single pillar of a building or structure to those that support entire communities and cities

the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. The molar mass is a bulk, not molecular, property of a substance. The molar mass is an average of many instances of the compound, which often vary in mass due to the presence of isotopes

The LSZ reduction formula provides a way of relating correlation functions to scattering amplitudes.

Nanotechnology is a field of research and innovation concerned with building 'things' - generally, materials and devices - on the scale of atoms and molecules

In year 2008, Satoshi Nakamoto invented the bitcoin

A plane's engines are designed to move it forward at high speed. That makes air flow rapidly over the wings, which throw the air down toward the ground, generating an upward force called lift that overcomes the plane's weight and holds it in the sky.The wings force the air downward and that pushes the plane upward.

Elon Musk's investments in bitcoin negate the environmental impact of every Tesla ever built.

Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate. They don't technically drown, because they don't inhale the water, but they do die from a lack of oxygen. Fishing equipment, such as some types of hooks, can damage the gills.
