Ask HN: Counting every unique sight in a lifetime

3 点作者 garyiskidding大约 1 年前
Pondering while walking that our eyes fall on innumerable objects, places, faces, even digital media like photos, videos and so many things around us (both physical and digital subjects).<p>While there is some work done on how much of it can we remember at a given time, do you wonder how big our entire visual vocabulary be if we count every object, face, place (any subject that can be uniquely, visually memorized - physical or digital) that falls before our eyes, and sum up the count over our lifetimes ?<p>This will vary between people and their environments, but I am still amazed by the potential size of this passive count of subjects that we process visually, even tough we may forget much of it.<p>How would one go about estimating an approximate range of total things that we see in our lives? It&#x27;d be our personal visual entropy vs others.

I bet we don’t forget most of them because they are not being remembered to begin with.<p>I think we only short-long term remember something we put our aware attention to, at least for a moment.<p>The details of our memories are reconstructed, not recalled from some storage.<p>Afaik. I am not a neuroscientist )

Does each leave of trees count as a different one?<p>When you eat chicken, do you count the chicken or each bone?
