Collapsibility deals with the conditions under which a conditional (on a covariate W) measure of association between two random variables Y and X equals the marginal measure of association. We have discussed the average collapsibility of certain well-known measures of association, and also with respect to a new measure of association. The concept of average collapsibility is more general than collapsibility, and requires that the conditional average of an association measure equals the corresponding marginal measure.

Our current question of philosophical enquiry is that how emotion, mostly empathy, plays a key role in moral cognition. The role of feelings in cognition is a subject of investigation in philosophy. The cognitive, aesthetical, ethical and psychological functions of feelings are discussed among others to underline our behavioural, cognitive, ethical and existential meaning. In the text books of philosophy moral cognition has often been considered a rational activity where one makes moral judgments based on a rational assessment.

Working in an institution of higher education, we worry about whether students are really ‘getting it’. Is our teaching effective in exciting students into learning about core concepts? Are they able to develop, apply and transfer the required concepts and skills to solve problems? In our research, we design and develop technology enhanced learning systems to promote students’ pan-domain thinking skills. We focus on engineering and science domains, using disciplinary content as a vehicle to develop the relevant thinking skills.

A general purpose circuit simulation packaged called SEQUEL has been developed at IIT Bombay. SEQUEL is particularly suitable for teaching coursesin electronics and power electronics. It has a graphical user interface (GUI) which allows the user to enter the circuit in a schematic form, set component values and simulation parameters, and view the simulation results. It also allows exporting of circuit schematics and the simulation plots so that they can be included in reports and presentations.

Did you know that many molecules have a ‘handedness’? That is, these molecules are distinguishable from their mirror image, like our left and right hand. But why should we care about it? It turns out that certain drugs and medicines may have their “mirror-twin” which could be toxic rather than medicinal! Through his theoretical contribution to quantum mechanics and ultrafast optics, Prof.

A novel theoretical framework for a magnetic field tunable radio frequency oscillator has been developed.The proposed device, when realised, would play a major role in  the nanoelectronics field, specifically as integrable clocks in futuristic logic circuits.

IIT Bombay and TIFR researchers demonstrate a method to turn heat into usable spin current
