Precision at its Peak: Cosmos Explores CSIR-NPL ⏱️🌡️💨 When it comes to the ultimate standards of measurement and scientific discovery, there is no better place to look On October 17, 2025, students from the Department of Physics embarked on an insightful field visit to the prestigious CSIR-National Physical Laboratory (CSIR-NPL). Fascinating projects we explored: The Cesium Atomic Clock: Witnessed how the absolute 'second' is defined with extreme precision—the backbone of GPS and global communications Redefining Temperature: Learned how temperature measurements are shifting to fundamental constants using the Boltzmann constant for ultimate reliability Air Quality Index (AQI): Got an inside look at how AQI is calculated, breaking down the crucial roles of pollutants like PM2.5 and PM10. From defining fundamental physical quantities at a national level to maintaining global scientific standards, this visit truly redefined how we look at metrology and modern science 💡
