I've no idea why you would ask me this, I am neither a licensing expert
nor, yet, a contributor to Physics.
I'm guessing because I am interested in Debian packaging? Indeed Physics
in Debian would be nice!
According to https://www.gnu.org/licenses/license-list.html#ZLib :
"License of ZLib (#ZLib): This is a free software license, and
compatible with the GPL."

If the contents is the same, either one?

I don't understand what you mean with your last question.
For sure there's interest in having a
Debian-Free-Software-Guidelines-complying source to hopefully have
Debian distribute this activity. If you could push this branch then it
would be a good first step, then we could work together with pkg-sugar
Team to upload it. Physics should be among the desired activities for
Sugar Blend Huayruro <https://wiki.debian.org/SugarBlend/Huayruro>
project, not sure why it's not listed.
