Judgement is also free, apparently. Kids these days, amirite?

YouTube is an amazing place to learn new skills and if you want to learn how professionals deploy code, a peek behind the AWS curtain can be very helpful even if it is too expensive for your toy website.

Adding to the original post, yes, a lot of things are free now. Sometimes I feel overwhelmed by the sheer amount of resources available on the internet. At the same time, many topics turn into deep rabbit holes if you look closely enough.

For example, I never realized how much there is to learn about something as simple as a bolt. To me, it was just a cylinder with helical grooves. Then I watched the video “Life of Bolts” on YouTube and was amazed by the number of steps and processes required to manufacture a high-precision, high-performance bolt for a Formula 1 car. Another eye-opening moment was watching “Origin of Precision.” It completely changed the way I look at everyday objects.

Once I started digging deeper into bolts, I discovered how many fields are connected to making them: materials science, process engineering, manufacturing engineering, metrology, precision engineering, and more. I have even come across PhD theses focused on bolts, O-rings, and seals. One time I found a technical paper on O-ring modeling from NASA’s technical server, and it was full of complex partial differential equations. It honestly surprised me how much knowledge and effort go into designing and producing things that seem so simple.

It makes me realize that the biggest bottleneck in learning anything deeply is mathematics. At the same time, you also need some philosophical grounding to ask the right questions, along with the willingness to learn and apply knowledge in the real world.
