Science & Mathematics Questions & Answers

In the 17th century, Sir Isaac Newton discovered the universal gravitational force. In the 21st century, Navinchandra K Shah, Prof. P N Jain and Prof. P P Jain of Hubli discovered a universal repulsion force (URF). It’s an astronomical force exerted by the sun and stars and therefore called stellar repulsion force (SRF). The science which deals with repulsive phenomena …

Stevenson’s Screen is a wooden box fitted into a steel frame, specially designed to protect weather instruments like thermometer, barometer, etc. from the sun’s rays and other natural heat radiation. British civil engineer Thomas Stevenson designed the first Stevenson’s Screen in 1818. In order to prevent direct sunlight falling on the instruments, it was designed so the door opens to …

Spider silk, also known as gossamer, is a protein fiber spun by spiders. Spiders use their silk to make webs. They can also suspend themselves using it. Many small spiders use silk threads for ballooning, the scientific term for the dynamic kiting spider lings (mostly) used for dispersal. They extrude several threads into the air and let themselves get carried …

Soap is made largely from fats or oil, with a variety of other ingredients. Before the introduction of soap in the 1st Century A.D. people ‘washed’ themselves and their clothes with fuller’s earth, a fine clay-like substance that loosens oil and dirt. People first made their own soap by saving scraps of fat and boiling them in an iron pot. …

This is a new and promising technology in the field of wireless and mobile communications in which capacity and performance are usually limited by two major impairments — multipath and co-channel interference. Multipath is a condition that arises when a transmitted signal undergoes reflection from various obstacles in the environment. This gives rise to multiple signals arriving from different directions …

Sleep walkers have problems with the brain stem mechanism concerned with movement. When sleep walking is caused by an imbalance of secretions, or by a poor nervous state (i.e., depression, or anxiety) the problem may be temporary. When it is due to injury of the nerve centers, the problem is permanent. Whatever the causes, we must never be impatient or …

In Physics and Mathematics, singularity is defined as a point at which a complex function is undefined because it is neither differentiable nor single-valued while the function is defined in every neighbourhood of the point. Specifically, a quantity which approaches infinity as another parameter goes to zero. Like 1/x when x approaches zero. In astronomy, singularity is a hypothetical region …

Seaflux is a study of the changes in oceans and its waves affected by momentum, heat and quantum of water. It involves creation of comparable data sets and constant observation about the effect of heat and momentum on the ocean front to increase our forecasting abilities about nature and sea behaviour.

This is an infections disease most prevalent among children but which is relatively uncommon now a days. There is a rash on the face and body, accompanied by fever. The rash flakes off after a few days. The principal treatment is penicillin. As with many infectious diseases, once a patient has recovered from scarlet fever he or she is normally …

Electromagnetic waves which exist only in the vacuum of empty space constitute an ocean of infinite energy called scalar energy. These new waves of energy are called “longitudinal” EM (electromagnetism) to distinguish them from “transverse” EM. Scalar energy was first announced by Thomas E Bearden. However, his ideas have received no noteworthy support in the scientific community. A scalar pendant …
