Science and technology questions are a staple in almost every Public Service Commission exam in Nepal. Memorizing key theories and their founders can give you a significant edge in the General Knowledge section.
Introduction
In the competitive landscape of Loksewa and Teacher Service Commission (TSC) exams, the “Science and Technology” section often features questions about foundational scientific discoveries. This guide provides a concise yet comprehensive list of major scientific theories and the brilliant minds behind them. Understanding these proponents is not just about memorization; it is about recognizing the milestones that shaped modern physics, biology, and chemistry. Whether you are preparing for the Section Officer, Nayab Subba, or Kharidar level, this reference will help you secure vital marks in the GK paper.
Essential Scientific Theories and Their Proponents
The history of science is marked by revolutionary ideas that changed our understanding of the universe. For exam purposes, you should focus on the following key theories:
- Law of Gravity: Sir Isaac Newton’s work in the 17th century laid the groundwork for classical mechanics.
- Theory of Relativity: Albert Einstein redefined space and time, a frequent topic in high-level Loksewa exams.
- Theory of Evolution: Charles Darwin’s “Origin of Species” remains the cornerstone of modern biology.
- Cell Theory: Developed by Schleiden and Schwann, this theory explains the basic unit of life.
- Big Bang Theory: Georges Lemaître proposed the expansion of the universe, which is a key concept in cosmology.
- Atomic Theory: John Dalton provided the first scientific description of the atom.
- Quantum Theory: Max Planck’s work led to a new understanding of atomic and subatomic processes.
- Laws of Inheritance: Gregor Mendel, the father of genetics, established how traits are passed through generations.
| सिद्धान्त (Theory) | प्रवर्तक (Scientist) |
|---|---|
| गुरुत्वाकर्षणको नियम (Law of Gravity) | सर आइज्याक न्युटन |
| सापेक्षतावादको सिद्धान्त (Theory of Relativity) | अल्बर्ट आइन्स्टाइन |
| क्रमविकासको सिद्धान्त (Theory of Evolution) | चार्ल्स डार्विन |
| कोष सिद्धान्त (Cell Theory) | श्लाइडेन र स्वान |
| बिग ब्याङ सिद्धान्त (Big Bang Theory) | जोर्जेस लेमेत्रे |
| परमाणु सिद्धान्त (Atomic Theory) | जोन डाल्टन |
| क्वांटम सिद्धान्त (Quantum Theory) | म्याक्स प्लाङ्क |
| वंशाणुगत नियम (Laws of Inheritance) | ग्रेगर मेन्डल |
Key Takeaways
- Sir Isaac Newton and Albert Einstein are the most frequently asked proponents in the physics category.
- Biology-related questions often focus on Charles Darwin (Evolution) and Gregor Mendel (Genetics).
- The Cell Theory was a collaborative effort by two scientists: Matthias Jakob Schleiden and Theodor Schwann.
- Understanding the Big Bang Theory is essential for questions related to the origin of the universe.
Common Mistakes
- Confusing the proponents of similar-sounding theories, such as mixing up Atomic Theory (Dalton) with Quantum Theory (Planck).
- Forgetting that the Big Bang Theory was proposed by Georges Lemaître, often incorrectly attributing it solely to Edwin Hubble.
- Ignoring the dual authorship of the Cell Theory; both Schleiden and Schwann must be remembered.
FAQ
Q1: Who is known as the Father of Genetics? A1: Gregor Mendel is known as the Father of Genetics for his pioneering work on the laws of inheritance.
Q2: Which theory explains the origin of the universe? A2: The Big Bang Theory, proposed by Georges Lemaître, is the leading explanation for how the universe began.
Q3: What is the difference between the Law of Gravity and the Theory of Relativity? A3: Newton’s Law of Gravity explains the force between masses, while Einstein’s Theory of Relativity explains gravity as the curvature of spacetime.
Q4: Who proposed the Atomic Theory? A4: John Dalton is the scientist who proposed the modern Atomic Theory.
Q5: Which scientists are responsible for the Cell Theory? A5: The Cell Theory was developed by the German scientists Matthias Jakob Schleiden and Theodor Schwann.
By mastering this list, you will be well-prepared for any matching or multiple-choice questions regarding scientific proponents in your upcoming Loksewa examinations.
