Which is harder: physics or chemistry?
TLDRThe video script explores the comparative difficulty of physics and chemistry, highlighting different teaching paradigms and cognitive learning styles. It explains that chemistry is often considered easier due to its use of concrete concepts and pyramidal learning style, while physics employs a more challenging pillar or stovepipe approach. The script also delves into the mathematical aspects of both subjects, noting that physics requires a deeper understanding of calculus and vector concepts. Furthermore, it touches on Piaget's cognitive theory of development to discuss how individuals' learning preferences can affect their perception of the subjects' difficulty.
Takeaways
- 📚 The speaker does not definitively say that physics is harder than chemistry but notes that the way physics is taught often makes it seem more challenging.
- 🏫 Two teaching styles are discussed: the pyramidal learning paradigm, which involves repetitive tasks and is used in subjects like chemistry, and the pillar or stovepipe learning paradigm, which is more advanced and used in physics and engineering.
- 🧠 People have different learning styles, with some excelling in repetitive tasks (pyramid learning) and others in conceptual understanding (pillar learning).
- 🔬 Chemistry is often considered easier because it uses more concrete concepts, which are learned before abstract concepts according to Piaget's cognitive theory of development.
- 📈 Advanced topics in physics, such as general relativity, special relativity, and quantum mechanics, introduce complexity and require advanced mathematical concepts like calculus and linear algebra.
- 📉 Physics can be made easier by learning foundational mathematical concepts in math classes before encountering them in physics.
- 🔬🔬 Introductory physics labs are often easier than chemistry labs because they do not involve handling fluids and focus on solid-state mechanics, optics, and electronics.
- 🤔 The difficulty of understanding physics or chemistry theories depends on the individual and their cognitive development in terms of concrete and abstract thinking.
- 🔄 Chemistry involves a lot of conservation laws and is often less mathematical than introductory physics, making it more accessible for those who are not as strong in math.
- 🔄 Physics, on the other hand, involves representing different points of view and understanding abstract concepts like vectors and symmetry, which can be more challenging.
- 🎓 The speaker's personal experience found chemistry to be easier overall, with the most difficult part being memorization, whereas physics required more effort in mastering equations.
Q & A
Which teaching style is described as 'pyramidal learning paradigm' and what does it involve?
-The 'pyramidal learning paradigm' involves teaching students simple tasks with a lot of repetition to aid memorization. As the problems become more complex, they decrease in number, but the operations within each problem increase. This style is commonly used in teaching languages, mathematics, and notably chemistry.
What is the 'pillar or stovepipe' learning paradigm and how does it differ from the pyramidal learning paradigm?
-The 'pillar or stovepipe' learning paradigm is a more advanced style where concepts are demonstrated and then students are expected to apply them to increasingly difficult problems. This differs from the pyramidal learning paradigm in that it relies on quick memorization and mastery of concepts rather than repetitive tasks. Physics is a notable example of a subject taught using this paradigm.
Why is chemistry often considered easier than physics for many people?
-Chemistry is often considered easier because it typically employs the pyramidal learning paradigm, which involves repetitious tasks that many people learn better from. This contrasts with physics, which is more commonly taught using the pillar or stovepipe learning paradigm.
What advanced topics in physics are mentioned as becoming particularly challenging?
-Advanced topics such as general relativity, special relativity, and quantum mechanics are mentioned as becoming particularly challenging in physics.
What mathematical concepts are essential for understanding quantum mechanics in physics?
-Mathematical concepts such as vector dot and cross products, multi-variable calculus, and linear algebra are essential for understanding quantum mechanics.
How does the speaker suggest making physics easier for students who struggle with the pillar learning approach?
-The speaker suggests that if physics instructors used a more repetitious problem-solving approach similar to the pyramidal learning paradigm, it could be made easier for students who don't learn well through the pillar approach.
What is Piaget's cognitive theory of development and how does it relate to learning scientific concepts?
-Piaget's cognitive theory of development is a model studied by a child psychologist to understand how children learn scientific concepts. The speaker found his theories useful in teaching and learning science, particularly in understanding cognitive difficulties.
According to the script, which type of concepts are used more in chemistry and why?
-Chemistry uses more concrete concepts, which are easier to teach and learn before abstract concepts. These include conservation laws, ordinal concepts, and concrete topics like weight as a measure of mass.
What are some abstract concepts mentioned in the script that are important in physics?
-Some abstract concepts mentioned in the script that are important in physics include direction in the vector sense, weight as a gravitational force, distance, time, vector direction, point of view, symmetry as invariance, and formal logic.
How does the script differentiate between the use of concrete and abstract concepts in chemistry and physics?
-The script differentiates by stating that chemistry involves a lot of conservation laws and is less mathematical, often using only one point of view and recognizing symmetrical patterns. Physics, on the other hand, involves representing different points of view, uses more abstract concepts, and is more mathematical from the beginning.
What was the speaker's personal experience with the difficulty of mastering equations in physics compared to memorization in chemistry?
-The speaker found mastering the equations in physics to be the most difficult part, requiring a lot of practice. In contrast, the most difficult part about chemistry was memorization, which required less effort than equation mastery.
Outlines
🔬 Teaching Styles and Conceptual Difficulty in Science
The paragraph discusses the relative difficulty of physics and chemistry, attributing it to the teaching methods rather than the subjects themselves. It introduces two teaching paradigms: the pyramidal learning paradigm, which involves repetitive tasks and gradual complexity, and the pillar or stovepipe learning paradigm, which requires quick mastery of concepts. The paragraph suggests that most people find chemistry easier due to its use of concrete concepts, while physics is more abstract and requires advanced mathematical concepts such as calculus. It also touches on Piaget's cognitive theory of development, which differentiates between learning concrete and abstract concepts and how this affects the ease of learning physics and chemistry.
📚 The Abstract and Concrete Nature of Scientific Disciplines
This paragraph delves into the abstract and concrete nature of scientific concepts, particularly focusing on the differences between physics and chemistry. It highlights that people who have mastered both types of concepts are bothered by logical contradictions, whereas those with only concrete skills may not be. The paragraph also contrasts the specific and general applications of concrete and abstract concepts, respectively. It discusses the prevalence of exceptions in chemistry and the fewer exceptions in physics, and how this relates to the learning process. The speaker shares personal experience with chemistry and physics, noting that while chemistry requires memorization, physics demands mastery of equations. The paragraph concludes with the speaker's preference for chemistry due to its less mathematical nature, especially for those who are not as proficient in math.
