Range of Light

The flow of photon particles is called light. Light is one type of electromagnetic wave. The light can not travel far enough because the light is scattered through various obstacles in the atmosphere of the Earth.  Because there is no atmosphere in the space, there is almost no presence of light distillatory material. So the light of a general intense light source can also pass an infinite distance. 

Building Super Conductor

Building Super Conductor 

By far inventions and discoveries made less progress regarding superconductivity none the less efforts to do so brought subtle break-throughs.
Starting with manufacture of economic superconductors for transmission and distribution of electrical power with minimal transmission losses.
We shall now talk about LTS(low temperature superconductors)
Superconducting is possible at low temperatures.
Having that simple fact in mind we need not go to the roots but only certain links,it is possible to know how to make superconductivity possible.
Thanks to Dr.Alex Muller for his contributions toward finding a cost effective cooling.
Liquid helium can do the job.
At -452°F it provides required low temperatures for superconductivity.
Moreover thick ceramic oxide compounds in place of copper  as transmission wires

is required to complete the job.
A High Voltage transmission cables with an extra layer(jacket) for the coolant to flow should be used for conducting power with minimal resistance.

Brain Tumor

Tumor is caused by abnormalities and excessive cell division. There are two types of tumors, namely benign tumor and malignant tumor. Although there is no possibility of cancer from benign tumors, but malignant tumor causes cancer. Now thinking about the brain, it is known that it is made with neurons and ganglion. Because the neuron's centrosome is inactive, it stays at the G-0 level of cell division, so they can not be divided. But in the first statement it has been said that tumor is caused due to extra cell division. This phenomenon may seem unusual. But brain tumors are actually occurring. In some rare cases, the centrosome part of these neurons of the brain became active and the cells could not be confined to the G-0 condition, so the neurons could be separated. But neurons can not control this division, so this division action reaches a greater level due to brain tumors.
