You must play with everything you come in contact with. By playing with everything you can discover how these things behave and work. You can apply the behavior all across the board. All objects are interconnected by the way they work. You can play with one thing and discover that a similar machine works in a similar way. You need to keep on playing with them in different ways so that you can make that new discovery. And when you make these discoveries you can implement them in respect to the thing you are building. These discoveries are infinite in nature and we can always strive to achieve them in perfection. But nothing is perfect. I’m talking about discoveries right in front of you which requires no in depth knowledge of any kind of physics. Although this would enhance your perception. But this is there for everyone to experiment with. And probably no knowledge of mathematics except for the basics. I would even go as far as not having to know anything except for the common sense that is already in you. Play with one thing and apply what you have discovered in another field. When playing with these objects you really have to ask yourself and keep in mind that you want to perceive something new. Repetition is key here. Determination to discover something new here is also key. You have to understand that everything around you is built by those that came before and has arisen out of knowledge. For example, logic. That cup of coffee in your hand at Starbucks was made with knowledge and skill. Things that seem so simple were made out of the rational mind. And this took time. What I want to do is to absorb that knowledge without being an expert in it. For example, I want to know what the cup is doing but I don’t want to make the cup over again. Of course, I can make a better cup but I don’t even want to do that. I want to use the cup to learn something new. Another aspect to this idea is that I want to perceive in a new way making the holding of the cup a new experience. It’s this experience back to back and again that I can learn something new about the cup’s behavior. It is this new behavior that I want to keep in my mind and remember because I can put it to good use without having to read on the dynamics of a cup. It is these small objects that I yearn to come into contact with and play with. Turn it. Throw it. Kick it. See what it does on its own and in your hand. This doesn’t happen over night in terms of improving your perception on how these objects work, it takes practice. So don’t expect that you do it once and you have it down pat. By playing the playing itself becomes a discovery you teach yourself how to play with these objects. The more you play with them the more solidification of this practice. To say the least and not having to invent anything new your perception alone of this phenomenon becomes richer and richer. And you will have that “aha” moment or moments. Bounce the object. Spin it and see what it does on it’s own. The more complex way of playing would be with two objects and see how they behave together you could even go to three or five and so as this becomes very complex. But for the beginner I would advise just using one object just to enhance your perception of the things you come in contact with.
