    Abstract:

Applications: One of the annoying side effects of being absorbed in a gripping novel is that the cup of tea on the table becomes cold. Unfortunately, the tea would not heat itself by absorbing the heat around it, just as pieces of a broken egg would not put themselves together or milk mixed in coffee would not separate by itself. Such things are irreversible, and define a fixed direction of time that from the past towards the future. This apparent progression of time is called the arrow of time.
Advantages: In the current study, Prof Verma discusses the specific case of time reversal for turbulent flows. If we write the equations of energy transfers in turbulent fluids for reversed time, we get equations that indicate a flow of energy from small scale to large scale. Such energy transfers are never observed in reality in dissipative systems. Thus, the energy flow from large scales to small scales defines forward moving time, whereas energy flow from small scale to large scale defines reverse time. Prof Verma suggests that we can apply this very principle of energy transfers to several other physical systems such as earthquakes, thermal convection and magnetohydrodynamic turbulence. However, researchers will need to work out the details of the energy transfers for these systems. We hope that this multiscale framework may be useful for resolving some of the longstanding issues on the arrow of time in physical and biological systems, as well as in cosmology, he concludes.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
