Thanksgiving Day is a national holiday on the fourth Thursday in November. It was first celebrated in 1621 by the Pilgrim Fathers after their first harvest. Ever since the Pilgrims gave thanks for their survival in the new land in 1621, Americans have flocked to their churches, “to add their own prayers for their country”. Most churches hold Thanksgiving services.
Thanksgiving is a family day, for it is customary for all members of the family to gather at home of their parents. The family eats a large traditional dinner which includes turkey with cranberry sauce and pumpkin pie. Many people go to football games. Some play games at home.

The Latin word for valency is valere, which means “to be strong”. The “strength” divides the elements into classes. The elements of class one have a valency of one: hydrogen and chlorine belong here. One packet of each can join to make hydrochloric acid. But to combine with one packet of oxygen which is in valency class two, there must be two packets of hydrogen (H2 + O  H2O - water).
Valency does not depend on size or weight of the element. It is its “strength of joining” (combining capacity).

Valency is the reason for the varying weights of the same element in different compounds. Once you know the valency of all the elements you can work out for yourself the formula for a chemical compound, provided you know its molecular weight, for valency tells you the number of atoms of one element that must combine with one atom of the other, and their total weights must add up to the molecular weight.

Radiation affects materials in a variety of ways because of the diversity of types of radiation and the difference in materials. Radiation effects may be either detrimental or beneficial to the desirable properties of a material. Some effects of radiation have been known for some time (e. g. discoloration of glass after long exposure to light; exposure of photographic film to electromagnetic radiation), while others have been recently observed with the advent of nuclear reactors and accelerators (very high-energy radiation). Radiation may be divided into two general groups:
1. electromagnetic radiation
2. radiation that is particulate in nature.

A body possesses energy when due to its position or condition it is capable of doing work and the work it can do is a measure of its energy.
Energy is of two forms: potential energy and kinetic energy. The potential energy of a body is the energy possessed by the body thanks to its position or configuration. For example, a lifted weight has potential energy due to the higher position into which it has been lifted since it can do work as it falls under the action of gravity. The potential energy of the weight in its highest position is the same as its kinetic energy after it has fallen to its lowest position.
