Principles of Scientific Investigation

Continuum progress of science is driven by people. It is the result of their curiosity, dedication, and creativity. In this perspective, although the scientific investigation itself in principle should be objective and rigorous, the truth that it reveals about the universe reflects continuous human endeavor and changing perspectives. It represents, to some degree, the manner…

Planetary origin of metabolisms during abiogenesis

Abiogenesis refers to a hypothetical natural process on the ancient Earth that non-living organic and inorganic matter together self-organize, forming some form of energy and chemical cycling system from which life emerged. Although the details of these distant processes are largely mysterious, it is reasonable to speculate that many features of these ancient non-living cycles…

Relationship between plants and animals

Relationships between plants and animals are not just a simple food chain relation. Most animals eat plants or their products, sure. Some plants take nutrients off from dead animals which have been decomposed by fungus. Animals all need oxygen. Plants produce the oxygen that animals need for survival. Looking at this relationship from a superficial…

On education: teaching and learning

More than 2300 years ago, the Chinese philosopher Confucius and his students developed what is perhaps the world’s oldest discussions on education, a collection of texts called “Xue Ji” (https://ctext.org/liji/xue-ji). Among these discussions, a simple statement was reasoned out: “teaching and learning help each other and would allow each other to grow”. Although little was…

Signatures of life

In this post, I break down the ideas behind a paper I recently read and liked very much. It is written by Sherry Cady, Jack Farmer, John Grotzinger, William Schopf and Andrew Steele, titled “Morphological Biosignatures and the Search for Life on Mars“, published in the journal Astrobiology in 2013. These are well-respected researchers in…

Raspberry Pi 3 Model B and DrDAQ

One important task for field/laboratory research is to record data for extended periods of time. These kinds of data acquisition are not suitable for human operators – not because we are incapable of handling the tasks, but the energy and time costs make the work unrealistic; the operator, even if a superman, can only focus…

Jupyter notebook for documenting your research

I recently discovered Jupyter Notebook. It is an excellent platform for research, because it records your learning progress as the code is developed, while being so flexible that you can document and share the code any way you want. It is the perfect way to code for scripting languages such as Python, MATLAB or R. I like it so…
