Evolution is sooooo false. Find out how.

Lenses are the most used things in optical devices like microscopes and telescopes. Bi-convex and bi-concave lenses are the most popular ones in use among school labs. Lenses use the phenomenon of refraction of light to form images.

The geometric centre of a lens is called its optic centre. The line passing through the optic centre and perpendicular to the plane of the lens is the principal axis. A light ray incident on a lens, after refraction appears to emanate from the principal focus in the case of a concave lens and passes through the focus in the case of a convex lens.

"The Homosexuals": Mike Wallace's controversial 1967 CBS report

CBS reports - "The Homosexuals"

"The Homosexuals" is a 1967 episode of the documentary television series CBS Reports. The hour-long broadcast featured a discussion of a number of topics related to homosexuality and homosexuals. Mike Wallace anchored the episode, which aired on March 7, 1967. Although this was the first network documentary dealing with the topic of homosexuality, it was not the first televised in the United States. That was The Rejected, produced and aired in 1961 on KQED, a public television station out of San Francisco.[1]Three years in the making, "The Homosexuals" went through two producers and multiple revisions. The episode included interviews with several gay men, psychiatrists, legal experts and cultural critics, interspersed with footage of a gay bar and a police sex sting. "The Homosexuals" garnered mixed critical response. The network received praise from some quarters and criticism from others for even airing the program.

#HOMOSEXUALITY although many claim it is just perfectly OK, it IS NOT part of our Creators original plan that men lay with men & women lay with women. Those that do, do so only out of lust and/or Spiritual and/or Mental CORRUPTNESS.

No matter what laws man brings about supporting #Abominations, you DO NOT have to obey these #CORRUPT laws.

Don't hate these abominations. They need help!

They can be helped, but they must first relieve themselves of their denial.

Atomic number is the basis for modern periodic table. Atomic number is the number of protons in the nucleus, it is also equal to the number of electrons in the atom.
Electronic configuration is the arrangement of electrons in an atom around its nucleus.

The important features of Bohr's atomic theory are:
Electrons occur in definite electronic shells.
The shells in an atom can be named alphabetically as K,L,M,N and so on.

A straight line intersects a circle at one or two point. The tangent to a circle is a line that touches the circle at one point. Secant intersects the circle at two points. The point at which the straight line touches the circle is called the point of contact or point of tangency.

We come across various patterns in our daily life. Arithmetic Progression in short AP is a sequence of numbers or terms in which each term except the first term is obtained by adding a fixed number or constant to the preceding term. This constant or fixed number is called common difference denoted by d.

Livings things exist in most places. Life exists even in open volcanoes. The term habitat refers to the surroundings where organisms live. Every habitat is home for a certain living creature. Habitat includes both living and non-living components. Plants and animals have different features that help them to survive in their own habitat. Habitat can be terrestrial or aquatic.

Terrestrial habitat refers to the land where all plants and animals survive. It includes deserts, forests and grasslands, as well as coastal and mountain regions. For example, camels and cactus plants live in deserts only.

If a and b are two natural numbers such that a3 = b, then b is called the cube of a.
If the units digit of a3 is b, then the cubes of all numbers ending with a will have their units digit as b.
The cubes of all numbers that end in 2 have 8 as the units digit. The cubes of all numbers that end in 3 have 7as the units digit.

Before the invention of the wheel, the only means of transportation was walking. For transporting goods, people used animals like donkeys, horses, mules, elephants, oxen, sled dogs, and even bison. Boats were also used as a means of transportation on water. The earliest boats were simple logs of wood with a hollow cavity.

The oldest wheel was discovered in Mesopotamia, and is believed to be over 5,500 years old. Fixed wheels for carts were invented around 3500 BC, according to some historians. After the invention of the wheel, man started using animals to pull vehicles that moved on wheels, and thus, bullock carts and chariots came into existence. Till the 19th century, most forms of transport used only animals.

The cells in our body perform functions like growth, excretion, reproduction, etc. A cell needs energy to perform these functions. The food we take in is converted into glucose by the digestive system. The cells of living organisms require a constant supply of oxygen to release energy. This is done by a process called breathing. Breathing involves two steps - one inhalation and one exhalation. The breath rate of human beings is 15 -- 18 breaths a minute. Air passes through the tiny hair in the nasal cavity, and then through the pharynx, larynx and windpipe before reaching the lungs. The hairs in the nasal cavity prevent the entry of dust particles and pollen. The mucous lining is present from the nasal cavity to the lungs.

An electric cell provides electricity to various devices that are not directly fed by the supply of electricity.

Electric Cell
An electric cell consists of two terminals. One is a positive terminal and the other one is a negative terminal. A chemical that helps produce electricity to connected devices.

Bulb
A bulb consists two terminals. A filament is a spirally wound wire inside the bulb supported by two thick wires at its ends. An electrical cell is connected to the terminals of a bulb so that electricity from the cell can pass through the bulb. This electricity makes the filament in the blub glow and emit light.

In the 19th century, James Joule studied a property, which says that "when an electric current flows through the filament of a bulb, it generates heat, and so the bulb becomes hot". This property is named the heating effect of electric current. When electric current flows through a wire wound around an iron bar, the bar behaves like a magnet. This magnet is called an electromagnet.An electromagnet is formed due to the magnetic effect of electric current. This magnetic effect of electric current was discovered by Hans Christian Oersted. Once, while preparing for a lecture, he noticed that there was a deflection in the needle of a magnetic compass kept near a wire that was connected to a battery. This deflection occurred every time the battery was switched on and off. He realized that a magnetic field is created around a current-carrying wire in a circuit.

Fractions with the same denominator are called like fractions.
Comparing like fractions: In like fractions, the fraction with the greater numerator is greater.

Two fractions are unlike fractions if they have different denominators.

Comparing unlike fractions: If two fractions with the same numerator but different denominators are to be compared, then the fraction with the smaller denominator is the greater of the two.

Usually, the comparison of quantities of the same type can be made by the method of difference between the quantities. However, a more meaningful comparison between the quantities can be made by using division, i.e. by verifying how many times one quantity is into the other quantity. This method is known as comparison by ratio.

Metals are used in making machinery, automobiles, aeroplanes, buildings, trains, satellites, gadgets, cooking utensils, water boilers, etc.
Sodium and potassium are soft metals that can be cut with a knife. Mercury is a liquid metal.

The metal base in an electric iron is for conducting heat, not electricity. Metals are very good conductors of heat, too. That's why cooking utensils, irons, heaters, etc. are all made of metals.
Metals can be easily shaped into wires. This property of metals is called ductility.
Metals can be easily shaped into thin flat sheets. This characteristic of metals is called malleability.
Metals make a sound when struck with hard objects. Metals can be polished to a shiny appearance. That's why gold and silver jewellery shine so much.

All numbers, including whole numbers, integers, fractions and decimal numbers, can be written
in the numerator-denominator form. A rational number is a number that can be written in the form p/q, where p and q are integers and q ≠ 0. . The denominator of a rational number can
never be zero. A rational number is positive if its numerator and denominator are both either
positive integers or negative integers. If either the numerator or the denominator of a rational
number is a negative integer, then the rational number is called a negative rational number.
