- lonelappde 6y agoHow is that "not a physics engine"?
- jcims 6y agoIt's more general than a physics engine in that it's predicting an expected outcome...it just so happens that the outcome here is largely dictated by physics. (At some level they all are but some more obviously than others)
- contravariant 6y agoIt's ridiculously bad at modelling quickly rotating objects.
- the_af 6y agoAnother fun example of how your brain predicts physics stuff is when you misjudge what something weighs. For example, if you subconsciously judge a glass is full of water but it's actually empty, as you try to lift it your arm will fly up awkwardly. This all happens without conscious thought. Don't tell me it never happened to you!
