Structure of the Earth

Structure of the Earth: The interior structure of the Earth is layered in spherical shells, like an onion. These layers can be defined by their chemical and their rheological properties. Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core. Scientific understanding of the internal structure of the Earth is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanoes or volcanic activity, analysis of the seismic waves that pass through the Earth, measurements of the gravitational and magnetic fields of the Earth.

This Topic is Part of Broad Physical features of World

The Crust

• It is the outermost solid part of the earth. It is brittle in nature. 
• The thickness of the crust varies under the oceanic and continental areas.
• Oceanic crust is thinner as compared to the continental crust. The mean thickness of oceanic crust is 5 km whereas that of the continental is around 30 km.

The Mantle

• The portion of the interior beyond the crust is called the mantle. The mantle extends from Moho’s discontinuity to a depth of 2,900 km.
• The mantle contains a weaker zone called asthenosphere.
• It is from this that the molten rock materials find their way to the surface.
• The material in the upper mantle portion is called magma.
• Once it starts moving towards the crust or it reaches the surface, it is referred to as lava.

The Core

• The coremantle boundary is located at the depth of 2,900 km. The core is made up of very heavy material mostly constituted by nickel and iron. It is sometimes referred to as the nife layer.
• The Core is divided into two layers: Outer Core and Inner Core.
• Outer core is in liquid state. The liquid outer core surrounds the inner core and is believed to be composed of iron mixed with nickel and trace amounts of lighter elements.
• Inner core is in solid state. Inner Core was discovered in 1936 by Inge Lehmann and is generally believed to be composed primarily of iron and some nickel. It is not necessarily a solid, but, because it is able to deflect seismic waves, it must behave as a solid in some fashion.

Nanotechnology in India and Rajasthan

Nanotechnology is the manipulation of matter on an atomic and molecular scale. Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. In its original sense, 'nanotechnology' refers to the projected ability to construct items from the bottom up, using techniques and tools being developed today to make complete, high performance products. The concepts that seeded nanotechnology were first discussed in 1959 by renowned physicist Richard Feynman in his talk There's Plenty of Room at the Bottom, in which he described the possibility of synthesis via direct manipulation of atoms. The term "nano-technology" was first used by Norio Taniguchi in 1974, though it was not widely known. Inspired by Feynman's concepts, K. Eric Drexler independently used the term "nanotechnology" in his 1986 book Engines of Creation: The Coming Era of Nanotechnology, which proposed the idea of a nanoscale "assembler" which would be able to build a copy of itself and of other items of arbitrary complexity with atomic control.

Nanometer as a Unit in Nanotechnology: In order to understand the unusual world of nanotechnology, we need to get an idea of the units of measure involved. A centimeter is one-hundredth of a meter, a millimeter is one-thousandth of a meter, and a micrometer is one-millionth of a meter, but all of these are still huge compared to the nanoscale. A nanometer (nm) is one-billionth of a meter, smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair. As small as a nanometer is, it's still large compared to the atomic scale. An atom has a diameter of about 0.1 nm.

Muscles and its three types

Muscles play important role in human body.
1. Without muscle, humans could not live. The primary job of muscle is to move the bones of the skeleton, but muscle also makes the heart beat and constitutes the walls of other important hollow organs.
2. Muscle is a soft tissue found in most animals. Muscles function to produce force and motion.
3. Muscle are primarily responsible for maintaining and changing posture, locomotion, as well as movement of internal organs, such as the contraction of the heart and the movement of food through the digestive system via peristalsis.

There are three types of muscle tissue:
1. Skeletal muscle: This type of muscle creates movement in the body. There are more than 600 skeletal muscles, and they makes up about 40 percent of a person’s weight. When the nervous system signals the muscle to contract, groups of muscles work together to move the skeleton.
2. Cardiac muscle: Cardiac muscle is involuntary muscle. This type makes up the walls of the heart and creates the steady, rhythmic pulsing that pumps blood through the body from signals from the brain.
3. Smooth muscle: Another involuntary muscle type, smooth muscle makes up the walls of hollow organs, respiratory passageways, and blood vessels. Like cardiac muscle, smooth muscle also contracts in response to stimuli and nerve impulses.

Risks of Nuclear Power

Risks of Nuclear Power: Nuclear power, or nuclear energy, is the use of exothermic nuclear processes, to generate useful heat and electricity. The term includes nuclear fission, nuclear decay and nuclear fusion. Presently the nuclear fission of elements in the actinide series of the periodic table produce the vast majority of nuclear energy in the direct service of humankind, with nuclear decay processes, primarily in the form of geothermal energy, and radioisotope thermoelectric generators, in niche uses making up the rest. Fukushima-Daichii nuclear power plant on March 16, 2011, after an 8.9 magnitude earthquake and tsunami set in motion a chain of disastrous events at the facility. Here is some of Major Risks of Nuclear Power.

Radiation: The principal risks associated with nuclear power arise from health effects of radiation. This radiation consists of subatomic particles traveling at or near the velocity of light---186,000 miles per second. They can penetrate deep inside the human body where they can damage biological cells and thereby initiate a cancer. If they strike sex cells, they can cause genetic diseases in progeny. Radiation occurs naturally in our environment; a typical person is, and always has been struck by 15,000 particles of radiation every second from natural sources, and an average medical X-ray involves being struck by 100 billion. While this may seem to be very dangerous, it is not, because the probability for a particle of radiation entering a human body to cause a cancer or a genetic disease is only one chance in 30 million billion
Reactor accidents: The nuclear power plant design strategy for preventing accidents and mitigating their potential effects is "defense in depth"--- if something fails, there is a back-up system to limit the harm done, if that system should also fail there is another back-up system for it, etc., etc. Of course it is possible that each system in this series of back-ups might fail one after the other, but the probability for that is exceedingly small.
Radioactive Waste: The radioactive waste products from the nuclear industry must be isolated from contact with people for very long time periods. The bulk of the radioactivity is contained in the spent fuel, which is quite small in volume and therefore easily handled with great care. This "high level waste" will be converted to a rock-like form and emplaced in the natural habitat of rocks, deep underground. The average lifetime of a rock in that environment is one billion years. If the waste behaves like other rock, it is easily shown that the waste generated by one nuclear power plant will eventually, over millions of years (if there is no cure found for cancer), cause one death from 50 years of operation. By comparison, the wastes from coal burning plants that end up in the ground will eventually cause several thousand deaths from generating the same amount of electricity.
Other Radiation Problems
The effects of routine releases of radioactivity from nuclear plants depend somewhat on how the spent fuel is handled. A typical estimate is that they may reduce our life expectancy by 15 minutes.
Potential problems from accidents in transport of radioactive materials are largely neutralized by elaborate packaging. A great deal of such transport has taken place over the past 50 years and there have been numerous accidents, including fatal ones. However, from all of these accidents combined, there is less than a 1% chance that even a single death will ever result from radiation exposure. Probabilistic risk analyses indicate that we can expect less than one death per century in U.S. from this source.
Mining uranium to fuel nuclear power plants leaves "mill tailings", the residues from chemical processing of the ore, which lead to radon exposures to the public. However, these effects are grossly over-compensated by the fact that mining uranium out of the ground reduces future radon exposures. By comparison, coal burning leaves ashes that increase future radon exposures. The all-inclusive estimates of radon effects are that one nuclear power plant operating for one year will eventually avert a few hundred deaths, while an equivalent coal burning plant will eventually cause 30 deaths.

Ten Percent Law by Lindeman

Ten Percent Law: Ten percent law for the transfer of energy from one trophic level to the next was introduced by Lindeman (1942). According to this law, during the transfer of energy from organic food from one trophic level to the next, only about ten percent of the of energy from organic matter is stored as flesh. The remaining is lost during transfer, broken down in respiration, or lost to incomplete digestion by higher trophic levels. The ten percent law suggests or implies that exactly 90% of the energy is lost in the transfer at each trophic level, and that only 10% is passed on as useable biological energy. That implied preciseness is misleading, however, and is one of the reasons that many scientists discount the concept, even label it a myth. Instead, it should be considered a rule of thumb, a teaching device, or perhaps best, a mnemonic device that serves as a reminder of the striking inefficiencies of natural systems.

The ten percent law does stand for a real fact of nature: most of the energy available at one level in an ecosystem is lost in the transfer to the next level. A very small percentage of the light energy that reaches the leaf surface of plants is actually assimilated, or turned by photosynthesis into organic compounds. Most of the light energy absorbed by plants is converted directly to heat and lost. Many plant parts are inedible by herbivores (the next trophic level) and is lost for energy transfer. The plants use much of the energy absorbed to live, as do the herbivores that eat them. So if there are 40,000 kg of producers, how many kg of primary consumers are there? 40,000 kg/ 10 = 4,000 kg. How many kg of secondary consumers? 400 kg How many kg of tertiary consumers? 40 kg
Questions based on Ten Percent Law:

Q.1 Ten percent law is given by
A. Lindmann
B. Goldmann
C. Beckmann
D. None of these
Ans: A

Q.2 If the energy available to the plants from the sun is 20,000J. What would be the energy available to the lion in the food chain , Plant? Dear? Lion
A. 20J
B. 200J
C. 2000J
D. 20000J
Ans: B

God particle or Higgs boson

What is God particle: Higgs boson or or God particle is an elementary particle initially theorised in 1964, and tentatively confirmed to exist on 14 March 2013. The "God particle" is the nickname of a subatomic particle called the Higgs boson. In layman’s terms, different subatomic particles are responsible for giving matter different properties. One of the most mysterious and important properties is mass. Some particles, like protons and neutrons, have mass. Others, like photons, do not. The Higgs boson, or “God particle,” is believed to be the particle which gives mass to matter. The “God particle” nickname grew out of the long, drawn-out struggles of physicists to find this elusive piece of the cosmic puzzle.  The “standard model” of particle physics is a system that attempts to describe the forces, components, and reactions of the basic particles that make up matter. It not only deals with atoms and their components, but the pieces that compose some subatomic particles. This model does have some major gaps, including gravity, and some experimental contradictions. The standard model is still a very good method of understanding particle physics, and it continues to improve. The model predicts that there are certain elementary particles even smaller than protons and neutrons. As of the date of this writing, the only particle predicted by the model which has not been experimentally verified is the “Higgs boson,” jokingly referred to as the “God particle.”
Here are some pictures that may help you understand God Particle:
