Can The Human Body Be Expressed Mathematically?

[ZombieFeynman]

Consider a perfectly spherical human, ...

With only conservative forces!

Consider a perfectly spherical human, ...

...of uniform density...

 

[DennisN]

...of uniform density...

...floating in the vacuum of space...

Consider a perfectly spherical human, ...

I am very proud to say that I am as close to that ideal of perfection as humanly possible.

The second link, while superficial, at least sheds light on the sort of unpredictability found in human biology. It is undoubtably of more use than any simple remark on unpredictability on its own right.

Edit: I did not intend on derailing the topic, only to prompt clarification.

To the OP, perhaps you'd like to explore Cellular Automata or Conway's Game of Life. You might also want to hear more about the field of Artificial Life in general. A book you may want to eventually check out is The Computational Beauty of Nature.

For certain, these are a long way off from deterministic simulations of the whole human body (by a long shot!), but perhaps they are a start. Maybe even someday, someone asking questions like yours may extend these studies further.

ZF, my comment was a reminder that there are too many variables in the real human body. How one person responds to bacteria, virus, parasites, etc... is uncountable, and any drugs that would combat these can be affected by many unpredictable occurrences. It would be impossible for me to try to list and I am sure that you know that, we don't even know what issues may arise. So, no, reminding the OP how unpredictable the human body is is not *unimportant*. It's something they need to consider.

I have a question: can the human body be expressed mathematically? If so, how would you even go about starting to map out the algorithmic structure of something that's living (which would include molecular function, cellular function, etc. etc.)?

What would want to express? And in how much detail? Taking into account each particle is beyond reason, but a crude approximation for some purposes may be x=vt where x is your center of mass and v is your walking speed. In practice, you only use the level of detail you need.
