Our desire to manage made us dull. Or are we still engineers?

We work with engineers every day, some manage engineers, hiring engineers, looking for new engineering opportunities, and so on. But, when was the last time we asked ourselves “who is an engineer?”. Have we invested the time to understand the meaning of being an engineer? On these occasions, we like to start from the basis, from the official definition. As per Cambridge Dictionary: An engineer is “a person whose job is to design or build machines, engines, or electrical equipment, or things such as roads, railways, or bridges, using scientific principles”. It sounds like, the “scientific principle” is a key…

What is psychological inertia? or… What is wrong with us?

Have you ever been in a situation where while discussing different solutions for a problem, you and your group is trying to solve, people finding all kind of reasons why something is impossible or extremely difficult? The arguments might sound like “It’s very difficult”, “This solution is very expensive”, “It’s not going to work!”, or even “This is a stupid idea!” I am pretty certain you have. This phenomenon, and many more, are part of Psychological Inertia. Now, let’s dive into the details.   Definition I always like to start with the plain and dry definition. Unfortunately, Cambridge dictionary does…

Changes vs Innovations. What is the difference?

Our life is full of changes. We change apartments, cars, work, accept a new position, start learning, etc. We make a lot of changes at our work too – maintain equipment, clean the products, change vendors, and hire or fire people. And we can continue the list of possible changes endlessly. The question is, do we need these changes or not? Are they innovations or just changes? In most cases, people don’t bother much to analyze or even think about the reason for any change they make. Here, let’s do the simple analysis that everyone should do. And we’ll do…

Why Tantalum is so expensive? Why is it a problem? And what can be done about it?

“Our life would never be as advanced and comfortable as it is if not for the application of tantalum and niobium.” And this is right. This is what I wrote at the very beginning of my book about tantalum and niobium chemistry. Tantalum capacitors are everywhere: in our cellphones, computers, in about any electronic device you use. Due to the unique properties of tantalum, these capacitors provide a champion performance within the smallest size. Defeblators and pacemakers contain tantalum capacitors because of their reliability. Tantalum is the only material that is fully compatible with the human body; therefore, parts made…
