Question Categories


  • What are the main branches of science?

    Science is broadly categorised into three main branches: Physical Sciences (e.g., Physics, Chemistry), Life Sciences (e.g., Biology, Botany, Zoology), and Earth Sciences (e.g., Geology, Meteorology).

  • How does scientific research contribute to advancements in technology?

    Scientific research provides the foundational knowledge and understanding that drives technological innovations. Breakthroughs in fields like physics or chemistry often lead to new technologies or improvements in existing ones.

  • Why is the scientific method important?

    The scientific method provides a systematic approach to inquiry, ensuring that research is objective, repeatable, and based on empirical evidence. It’s a cornerstone of scientific integrity.

  • How often do scientific theories change?

    While foundational theories remain consistent, science is an evolving field. As new evidence emerges, theories can be refined or replaced to better fit the observed data.

  • What’s the difference between a scientific theory and a hypothesis?

    A hypothesis is an educated guess or prediction that can be tested. A scientific theory, on the other hand, is a well-substantiated explanation of some aspect of the natural world based on a body of evidence.

  • Are all scientific studies equally reliable?

    No. The reliability of a study often depends on its methodology, the sample size, and peer review. It’s essential to critically evaluate the source and design of scientific studies.

  • How do scientists ensure their experiments are unbiased?

    Scientists use controls, randomization, and blind or double-blind experimental designs to minimise bias and ensure objective results.

  • Why is peer review important in science?

    Peer review ensures that scientific research meets the standards of the scientific community. It provides an external check on the quality, validity, and relevance of research.

  • Can I trust science news reported in the media?

    While many media outlets provide accurate science news, it’s essential to cross-reference with original research papers or trusted science publications to ensure accuracy.

  • How can I stay updated with the latest scientific discoveries?

    Subscribing to scientific journals, attending seminars, joining science organisations, and following trusted science news outlets can help you stay abreast of the latest discoveries.


  • What is the difference between Information Technology (IT) and Computer Science (CS)?

    While both IT and CS deal with computers, IT focuses on the practical aspects of computer systems, including installation, administration, and networking. In contrast, CS delves into the theoretical and algorithmic foundations, emphasising areas like programming, data structures, and computational theory.

  • How has technology impacted our daily lives?

    Technology has revolutionised communication, transportation, entertainment, healthcare, and education, among other sectors. From smartphones to online banking, technological advancements have made tasks more efficient and accessible.

  • What are emerging technologies to watch out for?

    Artificial Intelligence (AI), Quantum Computing, Augmented Reality (AR), Virtual Reality (VR), and Blockchain are some of the rapidly evolving technologies that are shaping the future.

  • How can I protect my privacy online?

    Using strong, unique passwords, enabling two-factor authentication, being cautious about sharing personal information, and using encrypted communication tools can enhance online privacy.

  • What is the significance of open-source software?

    Open-source software promotes collaboration, transparency, and community-driven development. It allows users to view, modify, and distribute the software’s source code, fostering innovation and adaptability.

  • How do I stay updated with the latest tech trends?

    Following tech blogs, subscribing to technology magazines, attending tech conferences, and joining tech forums or communities can help you stay informed about the latest trends.

  • What is the role of technology in sustainable development?

    Technology offers solutions for sustainable energy, waste management, and resource optimization. Innovations like solar panels, electric vehicles, and smart grids are pivotal in addressing environmental challenges.

  • Are jobs at risk due to automation and AI?

    While automation and AI might replace certain repetitive tasks, they also create new job opportunities in fields like AI ethics, robotics, and data analysis. Continuous learning and adaptability are key to navigating the changing job landscape.

  • How do I ensure my devices are secure from cyber threats?

    Regular software updates, using trusted security software, avoiding suspicious links or downloads, and being cautious about granting app permissions can enhance device security.

  • What is the Internet of Things (IoT)?

    IoT refers to the network of physical devices, vehicles, appliances, and other items embedded with sensors and software that enable them to connect and exchange data over the internet, leading to increased efficiency and real-time data analytics.


  • What are the main branches of engineering?

    The primary branches of engineering include Civil, Mechanical, Electrical, and Chemical engineering. However, there are numerous sub-disciplines like Aerospace, Biomedical, Computer, and Environmental engineering, among others.

  • How does engineering differ from science?

    While both fields are deeply interconnected, science seeks to understand the natural world through observation and experimentation, whereas engineering applies scientific principles to design, build, and improve systems, structures, and devices.

  • What qualifications do I need to become an engineer?

    Typically, a bachelor’s degree in an engineering discipline is required. However, for advanced positions or specialisations, a master’s or doctoral degree might be necessary.

  • Is a Professional Engineer (PE) licence necessary?

    While not always mandatory, a PE licence can enhance credibility, allow for higher positions of responsibility, and is often required for roles that involve public safety.
