Energy efficiency of human machine

Living organisms require energy for every activity they perform. As I am keying in from the keyboard, energy is being used for movement of fingers, thought and coordination processes running in the brain. The immediate source of this energy in heterotrophic organisms, which include animals, fungi, and most bacteria, is the sugar glucose. Glucose is oxidized into carbon dioxide and water with the help of inhaled oxygen and in the process 2880 KJ/mol energy is released. Of course it would not do to simply “burn” the glucose in the normal way; the energy change would be wasted as heat, and… Read More »Energy efficiency of human machine

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… Read More »Idyllic Life

Those who live in Punjab must have seen the picture of tenth Sikh Guru Gobind Singh. He is depicted riding a horse with full regalia and a falcon sitting on his hand. The guru has in fact a title given to him as “Baajan Wala”. Baaz is the name of the falcon he is holding. The falcon is called Goshawk and Baaz is the female of species. Its counterpart male is called “Jurra” in the Punjabi. Also the female of the Baaz is much larger in size and esteemed for its preying prowess. The falcon was a prized possession for… Read More »Goshawk

Tarla Dalal: First Master Chef of India passes away

India is a potpourri of diverse cultures. People from different places outside the sub-continent had been migrating to India since ages. It is generally thought that most of the migrants whether entering for commercial purposes, in search of greener pastures for their cattle which was the case of Aryans, or for grabbing and establishing their hold came generally through the Western corridor. This was not the only way people entered India. Parsees came by boats and ships first to Gujarat and then spread to other parts of India especially Mumbai. Ahoms entered India in the North East. Arabs arrived in… Read More »Tarla Dalal: First Master Chef of India passes away

View from Window

The view from from window of my room at 4 O’clock in the Evening: It is 4 O’clock in the evening. The sunshine is becoming pale at the approach of the evening. The mornings, evenings and nights are becoming cooler. Sky is still clear. Sitting in the same room of my home on the third floor, I am looking at the scene out side from the window. The outline of trees looks like the drawing of a child making lines with a pencil which are not straight but serrated. The shadows and lights are playing exclusive games in the branches… Read More »View from Window
