Seeing an object involves perceiving light that is reflected from it, leading to a mutual recognition between the observer and the object. The term 'seeing' is primarily defined as the perception of light, with a well-established understanding of how eyes detect light and convert it into nerve signals. However, the process by which the brain interprets these signals into recognizable objects remains largely unexplored, although certain brain areas are known to be involved. The discussion emphasizes the complexity of visual perception and the need for more specific inquiries in future threads. Overall, the nature of seeing is a multifaceted topic that intertwines physics, biology, and neuroscience.

When you see something you actually see the light reflected from that object. Something of a good topic to discuss.

Do you have a question about it?
 
Seeing an object is "objectified" by having an object see you back with very little time delay. Then we might see "eye to eye".
 
The word 'Seeing' (in it's most usual context), can be pretty much defined as meaning the perception of light.
We have a very good understanding of how light is physically detected by eyes and how eyes generate nerve signals representing the light detected.
As for how the brain is able to translate the nerve signals as recognisable objects, as far as I know this remains largely undiscovered, other than that we do know that certain areas of the physical brain are involved.
 
With that, I think we will close this topic. @avito009 you may open a new thread on the topic, but make sure that you have a specific question in your opening post rather than just a vague statement.
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
