Basic Sciences: Opportunities and Challenges in the 21st Century

Abstract Basic sciences - including physics, chemistry, biology, and mathematics - underpin scientific and technological advancement. In the 21st century, their utility is further reinforced by global challenges like climate change, pandemics, digitalisation, and chasing the Sustainable Development Goals (SDGs). Whereas fundamental sciences create expansive horizons for interdisciplinary work and innovation with the help of digital tools such as AI and international collaboration, they are also subject to systemic hurdles. These are disproportionate funding allocation, excessive dependency upon bibliometry, inadequate support for early-career scientists in low- and middle-income countries (LMICs), and increasing issues related to research ethics, mental well-being, and employment insecurity within academia. This article investigates the twin landscape of opportunity and challenge in modern basic sciences. It emphasizes the imperative to rethink funding mechanisms, facilitate open science, foster inclusive public engagement, and reform research evaluation frameworks to reward long-term value and global justice. The author makes the case for a fresh, inclusive, and curiosity-fostered commitment to basic science to ensure that it remains a foundation of sustainable human development and innovation.
