Q.It is often said that the world is witnessing now a second industrial revolution, which will transform the society as radically as did the first. List some key contemporary areas of science and technology, which are responsible for this revolution.

Just as steam power and mechanisation defined the first industrial revolution, a cluster of late-20th/21st-century scientific and technological fields is transforming society today:

• Information technology and computing: the invention of the transistor and integrated circuit enabled computers to shrink from room-sized machines to devices in every pocket, transforming work, communication, and commerce.
• Telecommunications and the internet: satellite communication, fibre optics, and networking protocols have connected the globe in real time, changing how information, business, and social life operate.
• Biotechnology and genetic engineering: understanding of DNA and techniques such as recombinant DNA technology, genome sequencing, and (more recently) gene editing (e.g., CRISPR) are transforming medicine, agriculture, and industry.
• Materials science and semiconductor technology: new materials (from advanced alloys to superconductors to nanomaterials) underpin everything from electronics to renewable energy technology.
• Automation and robotics: increasingly capable automated systems are changing manufacturing and services. …

List contemporary fields of science/technology (IT, biotech, telecom, materials science, space technology) and briefly justify why each is societally transformative, paralleling th …
