DNA

Deoxyribonucleic acid or DNA, is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. The main role of DNA molecules is the long-term storage of information. DNA is often compared to a set of blueprints, like a recipe or a code, since it contains the instructions needed to construct other components of cells, such as proteins and RNA molecules. The DNA segments that carry this genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the use of this genetic information.DNA consists of two long polymers of simple...

Aum - The Symbol

Om or Aum, written in Devanāgari as ॐ and as ओम्, in Sanskrit known as pranava प्रणव, is a sacred/mystical syllable in the Dharma or Indian religions, i.e. Hinduism, Jainism, and Buddhism.Aum is most commonly pronounced as a long or over-long nasalized close-mid back rounded vowel, though there are other enunciations adhered to in received traditions.

KITES

A kite is a tethered aircraft. The necessary lift that makes the kite wing fly is generated when air (or in some cases water) flows over and under the kite's wing, producing low pressure above the wing and high pressure below it.This deflection also generates horizontal drag along the direction of the wind. The resultant force vector from the lift and drag force components is opposed by the tension of the one or more lines or tethers. The anchor point of the kite line may be static or moving (e.g., the towing of a kite by a running person, boat or vehicle).Kites are usually heavier-than-air, but there is a second category of lighter-than-air...
