Q & A

What is the commonality between Elon Musk, Black Panther, Kim Jong Un, and Sam Bankman-Fried as mentioned in the presentation?

The commonality between them is that they are all graduates of physics, as emphasized in the presentation to show how versatile a physics education can be.

How does the speaker define physics in the presentation?

Physics is defined as the science that studies how the universe works, much like understanding the mechanics of a game. The aim is to discover the underlying principles or 'mechanics' that govern how the universe operates.

What is the significance of the bottle-dropping example in the context of physics?

The bottle-dropping example illustrates how physics helps in understanding everyday phenomena, such as why the bottle falls and how long it takes, which can later be applied to more complex systems like elevators.

Why does the speaker emphasize the challenge rather than the difficulty of physics?

The speaker highlights that physics is not necessarily about being easy or hard, but about being challenging. The satisfaction comes from solving complex problems and understanding the fundamental principles behind various phenomena.

What principle is demonstrated using the spinning egg example, and how is it applied in real-world technology?

The spinning egg example demonstrates the principle of conservation of angular momentum. This principle is used in technologies such as drones for stabilization and in spacecraft for maneuvering.

Why does the speaker compare physics to playing Mobile Legends?

The speaker compares physics to Mobile Legends to show that both are challenging. Despite being difficult at times, people still play because they enjoy the challenge, just as one enjoys tackling the challenges in physics.

What does the speaker say about Oppenheimer and the creation of the atomic bomb?

The speaker uses Oppenheimer’s work on the atomic bomb to illustrate that physics isn’t always easy or fun, but it is extremely challenging and rewarding, especially when working with atomic-level physics.

How does the speaker describe the benefit of learning physics in relation to problem-solving?

The speaker states that physics teaches students how to break down complex problems into smaller, more manageable parts, and then solve them systematically, which is a valuable skill in any field.

What role does physics play in the context of Industry 4.0 according to the speaker?

Physics plays a crucial role in areas such as automation, material science, data science, and quantum computing, which are foundational to Industry 4.0. Automation, in particular, is a field the speaker is involved in.

What is the speaker's personal contribution to the field of automation in Industry 4.0?

The speaker works on designing automation machines in Indonesia, focusing on precision machines like CNC (Computer Numerical Control) machines for cutting metals. His role includes calculating forces and creating algorithms for the machines.
