What is Maya?

I am sure that people in the West might have heard the word Maya. In the Hindu mythology, Universe or the Maya is the dream of Hindu God Brahma which he dreams. Then, there was Narada his son, who was a very erudite sage. With his intelligence, he impressed so many Gods and they often discussed their problems with him and used his services as a messenger for communicating with each other because one of them may be in Himalayas while another in the down South. One day Brahma called upon Narada and offered him a single wish. The Narada …

In Search of Chemist’s pure water

Chemist’s pure water which is formulated as H2O exists only in the theory. In the laboratory too, it has to be prepared from the water from the tap. The reason isits high polarity and very dielectric constant which makes it is a potent solvent. It can dissolve ionic inorganic salts, polar organic compounds, acidic, basic and polar gases. It also carries suspended matter like clay particles which are in the form of colloids. Some of these are loosely suspended and separate out with time by sedimentation and other are stable and has to be destabilized by using defloucculants to settle …

Higgs Boson: The God Particle

How many fundamental particles make all what exists in the universe? In our days electrons, protons and neutrons were considered the fundamental particles making up the atoms. Atoms combined with each other according to some rules to make molecules which are the building blocks of the universe. As the research to probe into the heart of these fundamental particles advanced with the advent of high speed particle colliders, it has been found that itis after all not as simple as it looks. Only electron withstood the test of being the fundamental particle. It was shown that neutrons and protons are …

Changes in Periodic Table of Chemicals….

We know that everything in the universe is made from the atoms. They are the basic building entities. Atoms are not solid entities but are made of dense nuclei surrounded by fuzzy cloud of electrons whizzing in the outer. Nucleus is made of protons and neutrons. Things don’t not end here. Nature is very complex. Even the atoms of same elements can have different number of neutrons making them have different weights. Such atoms are called isotopes. Atoms of same element or different elements can combine in umpteen ways resulting in diverse molecules and different substances from very simple molecules …

Some snippets from childhood ?

I am 61 years old now and retired from the service. In the ample time at my disposal, the mind harks back and reel of memory rewinds on the spool of time and this time it stops at the days of my childhood. Our childhood was spent in the village called Manimajra. Nowadays it is in the Union territory of Chandigarh though at that time it was along with Chandigarh a part of Punjab. We were like most others in the village poor peasants with small landholdings. Parents were totally illiterate. In those days, nobody was serious about the education …

Concept of pH in Chemistry

Although the pH of a lake or polluted stream is seldom reported in the media, the people who are monitoring the health of the lake water record it daily religiously. But pH is quite an important physical property of water. pH of a stream gives an indication about the salts and other soluble matter present in the water. These soluble salts affect the organisms living in the water. Also changing pH in a stream can be an indicator of increasing pollution or some other environmental factor. As we know life on our planet is based on the water. Water is …

Idyllic Life

There is a piece of uncultivated land adjacent to our building. Land is scarce in Punjab. Every inch is under cultivation. So this piece of land with uneven surface must have been purchased by some builder for construction of high rise buildings. But at present it is as it is. Grass and shrubs are growing uninterrupted in this land. On the opposite end are dense woods where poplar and eucalyptus are growing majestically. Poplars are not complicated trees. They are straight with no branches stand like the sentries at attention. The eucalyptus trees have grown so high as to touching …

Animals cannot digest Cellulose

Most plants synthesize cellulose which they use to give strength to their bodies and make them withstand the vagaries of storms. It gives the shape to the trees and branches then expand the tree. Cellulose becomes the wood when trees become mature. Furniture is made of this material. It is obvious that cellulose is insoluble in water otherwise no one will use it in construction and furniture. Cellulose and starch and other carbohydrates consist of glucose molecules which are arranged in chains of different styles. In starch, two chains are intertwined. These chains get separated on boiling the starch in …

Observing the Nature

How often do we leisurely watch the nature around us? General answer will be not often. Do we sit out in the evening and watch the sun going down, its glow becoming golden, and shadows lengthening and blinking through the chinks in the trees? Do we watch the groups of birds flying towards their homes after spending their day in a far off place where the food is available to forage? Why, in the first place, they don’t make their resting places near the food. May be the supply is not available at one place throughout the year and their …
