What is nature?

Nature encompasses a vast array of scientific disciplines that explore the natural world.

What are the main features of nature?

  • Interdisciplinary Approach: Natural sciences like biology, geology, physics, chemistry, and ecology all contribute to understanding the natural world, its components, and the processes that govern it.
  • Focus on Observation and Experimentation: Scientists use observation, experimentation, and data analysis to understand natural phenomena, from the behavior of microscopic organisms to the formation of galaxies.
  • Emphasis on Hypothesis Testing: Developing and testing hypotheses through scientific methods allows researchers to build a comprehensive understanding of the natural world.

What are important sub-areas in nature?

  • Biology: Studies living organisms, their structure, function, growth, origin, evolution, and distribution.
  • Geology: Explores the Earth's solid, liquid, and gaseous features, its composition, structure, processes, and history.
  • Physics: Investigates the fundamental laws and principles that govern matter, energy, and their interactions in the universe.
  • Chemistry: Studies the composition, structure, properties, and behavior of matter, focusing on how elements combine to form compounds and how substances react with each other.
  • Ecology: Examines the relationships between living organisms and their environment, including the interactions between different species and their physical surroundings.
  • Astronomy: Focuses on celestial objects and phenomena like stars, planets, galaxies, and the universe as a whole.
  • Meteorology: Studies the atmosphere and its weather patterns, focusing on processes like precipitation, wind, and temperature.
  • Oceanography: Explores the physical and biological aspects of the ocean, including its currents, tides, marine life, and the composition of seawater.

What are key concepts in nature?

  • Natural Selection: A theory proposed by Charles Darwin, explaining how organisms with favorable traits are more likely to survive and reproduce, leading to evolution of populations over time.
  • Biodiversity: The variety of life on Earth at all levels, from genes to ecosystems, and its importance for ecosystem health and sustainability.
  • Ecosystem Services: The benefits that humans derive from nature, such as clean air and water, food production, and climate regulation.
  • Sustainable Development: Meeting the needs of the present without compromising the ability of future generations to meet their own needs, by considering the environmental impact of human activities.

Who are influential figures in nature?

  • Charles Darwin: Revolutionized our understanding of the natural world with his theory of evolution by natural selection.
  • Marie Curie: Pioneering physicist and chemist whose research on radioactivity led to significant advances in science and medicine.
  • Louis Pasteur: Microbiologist whose discoveries on vaccines and fermentation had a profound impact on public health.
  • Rachel Carson: Marine biologist and author whose book "Silent Spring" raised awareness of the dangers of pesticides on the environment.
  • Stephen Hawking: Theoretical physicist who made significant contributions to our understanding of cosmology, black holes, and the origins of the universe.

Why is nature important?

  • Understanding Our World: Understanding the natural world allows us to appreciate its complexity, predict natural phenomena, and develop sustainable practices.
  • Resource Management: Nature provides us with food, water, and essential resources. Studying natural systems helps us manage these resources responsibly.
  • Addressing Environmental Challenges: Climate change, pollution, and biodiversity loss are pressing issues. Studying nature is crucial for developing solutions to these challenges.
  • Scientific Progress: The study of the natural world drives scientific discovery and innovation across various fields, leading to advancements in medicine, technology, and engineering.

How is nature applied in practice?

  • Conservation Biology: Using scientific knowledge to protect endangered species and ecosystems.
  • Environmental Policy: Developing policies to address environmental challenges like pollution and climate change.
  • Agriculture: Developing sustainable agricultural practices that minimize environmental impact and improve food security.
  • Medicine: Discovering new drugs and treatments based on natural substances or by understanding biological processes.
  • Technology Development: Biomimicry, where engineers and designers draw inspiration from nature to create innovative solutions to problems.

Using and finding summaries, study notes en practice exams on JoHo WorldSupporter

There are several ways to navigate the large amount of summaries, study notes en practice exams on JoHo WorldSupporter.

  1. Starting Pages: for some fields of study and some university curricula editors have created (start) magazines where customised selections of summaries are put together to smoothen navigation. When you have found a magazine of your likings, add that page to your favorites so you can easily go to that starting point directly from your profile during future visits. Below you will find some start magazines per field of study
  2. Use the menu above every page to go to one of the main starting pages
  3. Tags & Taxonomy: gives you insight in the amount of summaries that are tagged by authors on specific subjects. This type of navigation can help find summaries that you could have missed when just using the search tools. Tags are organised per field of study and per study institution. Note: not all content is tagged thoroughly, so when this approach doesn't give the results you were looking for, please check the search tool as back up
  4. Follow authors or (study) organizations: by following individual users, authors and your study organizations you are likely to discover more relevant study materials.
  5. Search tool : 'quick & dirty'- not very elegant but the fastest way to find a specific summary of a book or study assistance with a specific course or subject. The search tool is also available at the bottom of most pages
