Research | Philosophy: Study

Scientific investigation is a structured yet creative process that requires intelligence, discipline, critical thinking, and practical wisdom. Drawing on insights from W. I. B. Beveridge’s The Art of Scientific Investigation and reflections by great thinkers like Francis Bacon and Theobald Smith, this guide highlights key principles to help young researchers navigate the path from curiosity to discovery.

1. Choose Your Problem Wisely

Successful research often begins with selecting a problem that is both interesting and accessible. As bacteriologist Theobald Smith noted, availability of materials and resources plays a crucial role. A talented researcher can usually find a suitable problem by focusing on what can realistically be studied, rather than chasing idealized questions beyond reach.

2. Understand What Is Already Known

Before diving into experiments, it’s essential to thoroughly review existing literature. Start with textbooks or recent review articles, which offer balanced summaries and point to key references. This helps avoid duplication and identifies gaps where new contributions are needed.

3. Attend Scientific Conferences

Conferences provide invaluable learning beyond reading papers. They demonstrate how knowledge builds collaboratively, how criticism is constructively applied regardless of status, and help researchers become familiar with the people behind the science. This exposure fosters a sense of community and sharpens critical thinking.

4. Beware Cognitive Bias

Scientists must guard against confirmation bias—the tendency to notice and remember information that supports existing views while ignoring contradictory evidence. Careful, tactful inquiry is required to separate objective observations from subjective interpretations.

5. Formulate and Test Hypotheses

Creative thinking is central to science. Using gathered data, researchers formulate multiple hypotheses to explain observations. The strength of these hypotheses lies in their test-ability: experiments or further data collection should be designed to prove or disprove them, guiding progress.

Observe → Hypothesize → Test → Refine.

6. Design Practical and Focused Experiments

After understanding the problem fully, select experiments that promise the most useful information and fit your technical capacity and resources. While exploring several angles early on can be beneficial, avoid dispersing efforts too widely. Focus on the most promising findings as they emerge.

7. Stay on the Path

The lame in the path outstrip the swift who wander from it.

Francis Bacon famously said, “The lame in the path outstrip the swift who wander from it.” This means that steady progress along a clear, well-chosen path can lead to greater success than rushing quickly but losing direction. For scientists, it emphasizes the importance of focus, discipline, and persistence in research, rather than being distracted by too many ideas or approaches.

8. See the Wood, Not Just the Trees

As Beveridge reminds us, “For creative thinking it is more important to see the wood than the trees.” While a student might become lost in technical details, a mature scientist gains enough perspective to understand the big picture. Francis Bacon aptly said that one must determine the relative value of knowledges, emphasizing that not all knowledge is equally useful. This holistic view allows scientists to prioritize and integrate information effectively.

9. Follow a Structured Approach

A typical sequence for investigations, especially in medical or biological fields, includes:

  • Critically reviewing the relevant literature.

  • Conducting thorough field or observational studies, supplemented by lab work.

  • Organizing and correlating information to define the problem and break it into specific questions.

  • Generating as many intelligent hypotheses as possible.

  • Designing experiments to test the likeliest hypotheses on the most crucial questions.

This structured yet flexible approach balances creativity with rigor.

10. Prioritize Valuable Knowledge

Reflecting Bacon’s wisdom, “We must determine the relative value of knowledges.” Santiago Ramón y Cajal also warns against wasting time on unrewarding subjects, which can clutter the mind and distract from meaningful research. Prioritization ensures that mental space and effort are devoted to the most promising and productive avenues.

Conclusion

Scientific investigation is a dynamic interplay of curiosity, disciplined thinking, and practical strategy. By selecting meaningful problems, critically reviewing knowledge, engaging with the scientific community, guarding against bias, staying focused on the right path, seeing the big picture, and designing targeted experiments, young scientists can navigate the complex journey from questions to answers. Embracing these principles nurtures both the mind and the community that drives science forward.

Operations | Structure: Soil Management

One of the most important foundation component of agriculture is the soil. The soil has three main purpose: retain water for the plants, provide nutrients to the plant and give physical support to the plant. Soil contains many minerals in it that is vital for plant growth. Soils differ in different regions because it contains one type of mineral more than other soil in other regions. This kind of mineral can come from volcanic activity as well as weathering activity. Soil has layers (or horizons). At the very top, humus can be found which is rich in organic matter (usually decomposing plant and animal matter). As we go deeper below the surface, the soil particles become bigger until we hit rocks (the parent material of soils). Soil is made up of sand, silt and clay. All sand, silt and clay are not the same. Sand is bigger in (particle) size than silt and silt is bigger in (particle) size than clay. The perfect soil for agriculture is said to be 40% sand, 40% silt and 20% clay, which is...
