Advantages of CAD: 5 Reasons to Go Digital

Construction drawings. Desk EngineerWhen working as an architect, one of the most important traits to have is the ability to visualize the finished product in your mind, before you even draw the first line of its blueprint. Once you start working on your blueprint, things become even clearer in your mind, and you get a pretty good idea of how the final product will look like; but what do you do when you need to share that idea with someone that doesn’t have the spatial visualization ability you have? This is where computer-aided design (CAD) comes into play, as it gives you the ability to create a 3D sketch of your product, and show everyone how it will look and work before actually building it.

Importance of Science: Understanding Our Past, Present and Future

importance of scienceCan you imagine a world without science? You wouldn’t have to worry about being late to work or finding your car keys because, well, jobs and cars wouldn’t exist. You would be living in a cave or a rudimentary built shelter, at best, wondering whether you’ll be able to hunt something for your next meal, or get killed and become some wild animal’s next feast in the process. The moment that early humans decided to take action into securing their survival marked the birth of science, as that’s the moment when they started asking themselves two vital questions about the world surrounding them: “How?” and “Why?”.

Basically, that’s exactly what science is about: understanding how things work and why, and the answers science gave us so far allowed us to survive, ensure our survival and improve our lifestyle in the process, so I don’t think it’s exaggerated to say that science is the most important element of our existence. If you want a proof of just how awesome science is, check out this online course on geology and you will learn about the origins of our planet, how it was formed and why it is in the form we know it today – starting from billions of years ago, all the way up to the present day.
