Fundamental and Derived Laws in Multiscale Systems

This article is a tribute to Phillip Anderson, who passed away on March 29, 2020.  Besides his pioneering works in condensed-matter physics, he also wrote extensively on the theme of reductionism and multiscale physics.

To understand an extensive, complex physical system, thinkers break it up into smaller components and try to understand the properties of the most minor microscopic components. This method helps us understand many complicated things around us, and has helped us solve a lot of real-world problems. But it does not help us understand certain phenomena, such as turbulence in fluids. A different way of thinking, a method that considers the physical system as a whole is needed in such cases. This method is called the multiscale analysis.

 Making sense of sound - Digital Audio Processing Lab at IIT Bombay

Humans communicate a lot non-verbally, thanks to the ability of our brain to understand tone. Would computers be able to do this? Currently capable of understanding plain text, they are struggling to learn the emotions behind the words, conveyed through tone. But these machines are catching up fast. Digital audio processing tools equip computers to understand various information in sound, including emotions.Prof Preeti Rao of the Indian Institute of Technology Bombay is an expert in sound processing—an approach that helps us do various useful things, one of which is removing unwanted sounds (or noise) from an audio clip. With her team at the Digital Audio Processing Lab, Prof Rao attempts to understand the nature of sound, reveal the information it may hold, and use it for, say, identifying tracks, melodies or the raga of a song.

Mini-fuel engines could replace batteries in the future

Scientists around the world have been actively looking for eco-friendly alternatives to conventional chemical-based batteries. In one such effort, researchers at the Indian Institute of Technology Bombay (IIT Bombay) have designed a micro-combustor that is efficient and environment-friendly. The study, funded by the Science and Engineering Board (SERB) and Department of Science and Technology (DST), has been published in various journals including Applied Physics Letters, Energy Conversion and Management, and Applied Energy.

Insights from Optics for Better Thermoelectric Devices

New design in thermoelectric devices can increase both output power and efficiency

A significant problem in electronic devices is the generation of heat during their operation. This phenomenon not only leads to the wastage of electric power but can also damage the device. Thermoelectric materials, which convert heat to electricity and vice versa, can be used to turn the generated heat back into electricity, thereby saving power and avoiding overheating of the device.

Getting more with less: Study proposes the design of an optimum quantum circuit

Nature is an enigma; an ensemble of complex structures and functions come together to form a variety of mesmerising artefacts, including life. Richard Feynman, the well-known American Nobel Laureate and physicist, famously said—"Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by golly it's a wonderful problem, because it doesn't look so easy".

Among all the calamities caused by climate change, an increase in the salinity of the soil is one. It is projected that, by 2050, about half of today’s arable land across the world will be affected by salinity. This increase would also hit India’s rice bowl, the Indo-Gangetic plains, which is projected to lose about 45% of the crop yield. When salinity increases, plants respond by absorbing less water, which affects their growth. How then do we help agriculturally vital crops cope with high salinity?

Nurturing a support system for India’s women scientists

Today is National Science Day—a day to celebrate the spirit of science and scientific temper across the county. It is a day to commemorate Sir C V Raman’s discovery of the Raman effect. This year, the theme of National Science Day is ‘Women in Science’, celebrating the contributions of women scientists to the field of science in India.
