Have you ever wondered why structures like cranes or bridges are so incredibly (35) __________? The secret often lies in a simple shape: the triangle. In structural engineering, not all shapes are equal. The triangle has a unique property that makes it essential for building stable structures, which is why engineers rely on it.

To understand this, first consider a square. If you push on a square frame, its corners bend easily, and it distorts into a diamond shape because its angles are not fixed. This tendency to deform can lead to structural (36) __________. Due to this weakness, squares are less reliable for bearing heavy loads without extra support.

A triangle behaves very differently. When force is applied, it is distributed along the sides. This inherent rigidity makes the triangle the (37) __________ geometric shape for building. Its fixed angles mean the structure resists deforming under pressure. Unlike a square, its angles (38) __________ simply change to absorb force; the sides must either compress or stretch.

This principle is visible everywhere. The sides of the triangle work together to distribute the load. (39) __________ is why you see networks of triangles in bridges and roof trusses. These structures (40) __________ the ability to support enormous weight over long distances, ensuring safety. Even bicycle frames use triangles to create a strong, lightweight body.

(41) __________ is this principle important for bridges, but it is also crucial for everything from radio towers to stadium roofs. The strength lies not in the material alone, but in the shape itself. (42) __________, the simple triangle is a cornerstone of safe and efficient engineering design.

In an era dominated by technology, a new global conversation has emerged in education: should learning to code be a fundamental part of every student's schooling? Once a specialized skill for a small group of experts, computer programming is now being viewed by many countries as a new form of literacy, as crucial as reading, writing, and arithmetic. The debate centers on whether coding should be a mandatory subject, preparing all young people for a future where technology is interwoven with every aspect of their lives.

Proponents argue that the value of learning to code extends far beyond a career in software development. The core of coding is computational thinking—the ability to break down a complex problem into smaller, manageable steps and create a logical solution. This skill is universally applicable, enhancing problem-solving abilities and logical reasoning in subjects from mathematics to music. Therefore, they see coding education as an essential tool for cognitive development, much like learning a musical instrument or a foreign language helps train the brain in unique ways, regardless of a student’s future career path.

This trend has a particular resonance in Vietnam, which is experiencing a rapid expansion of its tech industry. Vietnam's burgeoning tech sector, fueled by major domestic companies like FPT Software and a vibrant startup scene supported by coding bootcamps like CoderSchool, has created an enormous demand for skilled programmers. Because of its rapid growth, it offers significant opportunities and well-paying jobs, making programming an attractive field for many young Vietnamese. This local context makes the question of coding education not just a theoretical debate but a practical consideration for future career success.

However, the push for universal coding education is not without its critics. Some educators and parents worry about overburdening students with an already packed curriculum. They argue that forcing every student to learn the complexities of a programming language like Python or Java might create unnecessary stress and anxiety for those not naturally inclined towards it. These critics suggest that a more balanced approach, focusing on broad digital literacy—such as understanding how algorithms work, being safe online, and using digital tools effectively—might be more beneficial for the general student population than mandatory, in-depth coding classes.

Ultimately, the discussion is not just about creating more programmers. It is about equipping the next generation with the thinking skills to navigate a world increasingly shaped by algorithms and software. While making coding compulsory for everyone remains a contentious issue, there is a growing consensus that a foundational understanding of the logic behind technology is no longer optional. The challenge for educators, in Vietnam and around the world, is to find the right balance to prepare students for a future that is still being written in code.
