BEYOND REASON : THE INCREDIBLE SIXTH SENSE

Sixth sense, also known as a gut feeling or intuition is an ancestral ability we inherited from the first human beings. Although it is indeed a wonderful gift, there is no paranormal process behind it. Learn how to use your sixth sense to get the most out of it. One brain, two minds Humans have two different types of thinking: analytical and intuitive. The intuitive mind responds for the decision-making process beyond conscious awareness. It is fast and spontaneous and works based on pattern-recognition. It is also old and probably evolved in our ancestors as an alarm system for survival,…

THE REAL INVISIBILITY CLOAK

The dream of invisibility lives in human imagination. Invisible beings, invisibility cloaks, and unseen devices inhabit many fiction books and movies. In real life, not only magicians can make things disappear right before our eyes, using mirrors, scientists also have some hidden secrets. Learn about the real invisibility cloaks. A matter of perception We know our eyes deceive us all the time (See the article Eyes: Those pretty little liars ). The visible spectrum for the human eye comprises a wavelength range of 390 – 700 nm, which excludes ultraviolet and infrared light. Unfortunately, we cannot admire the elaborate flower…

EYES : THOSE PRETTY LITTLE LIARS

Can we trust our eyes? Sometimes our vision plays tricks on us; we can either ‘see’ things that are not even there or not see something that is right before our eyes. Learn how this is possible.

SOLAR CHARGE CONTROLLERS THE BATTERY LIFE ENHANCERS

Charge controllers, also known as charge regulators are an integral part of the solar power systems and are often termed as battery life enhancers. These devices limit the amount of current drawn and fed to the batteries bank, which stores DC energy from the solar panels. Life span of a battery is curtailed if overcharged and same is the case when current is drawn in an under charge condition. The charge controller circuit is intelligent enough to tackle both these situations by allowing or suppressing amount of charge to the batteries. In case of solar systems, Most 12 volts panels…

SOLAR INVERTERS – EFFICIENT AND ROBUST SOLAR POWER INVERTERS

Solar power is one of the most convenient and readily available form of renewable energy. Scientists have devised the methodologies and technologists have created the stuff employed for conversion of heat and light of solar rays into electricity available at our home outlets. Some specialized genre of semi conductor materials that exhibits photovoltaic effect i.e. these material produce direct current in response to incident light, are used in the fabrication of solar plates combined in the form of arrays. Each single plate is a combination of a huge number of solar cells with each cell producing voltage output in the…

INVISIBLE WALLS – LASER WALLS

Invisible Laser Wall In most of the strategic Hollywood movies having thrilling scenes of stealing money from a bank or some other kinds of precious and valuable artifacts from some museum etc you might have observed that there are a number of security systems. Among those systems a very famous security system is Invisible Laser Wall. As we know that light has three regions in which only one region is visible to a human naked eye. That region is known as Visible Region of light. The other two regions are Infra-Red and Ultra-violet regions. These both regions are invisible to…
