Does measured milk in, minus waste out, in newborn babies equals the increase of its weight. There must not be any conservation law violation. Are nitrogen, oxygen etc from air add-up.

Any studies to treat this subject ?

Perhaps there are studies, but I'm doubtful it's that simple. We lose mass through respiration and perspiration as well (unless you're considering those as "waste" too, but that'd be an uncommon use).

Why do you feel there would be any violation of the Law?

This seems like a very odd question to be honest.

All animals work with water and food in, minus waste out. Babies are no different.
The exact breakdown of the food in and quantity matters, as does the metabolism of the animal both chemically and energetically with regards to weight gain.

Are you thinking too simplistically, or not actually asking specifically enough?

to all replies

The matter subject is described clearly and fully, for the purpose of a discussion between a non-research scientist and non-research scientists. The ones who get the consequence will only fill the scope of such wonderings. Where science has reached now aided by technological innovation everything is reexamined and rethinked and measurments like these must be possible not to say easy.


"The exact breakdown of the food in and quantity matters, ......."
WHAT DOES IT MATTER.
All is needed is:
"Does measured milk in, minus waste out, in newborn babies equals the increase of its weight." We have conservation of mass to satisfy (and how air breathed is used, don't forget, atom by atom). If one uses animals in glass tube it's fine, will it change anything in our subject matter ?
Metabolism ? I am sorry, it is unlucky use of the word for here, consider the subject 2 to 3 levels higher than this.

"Why do you feel there would be any violation of the Law?" I am wondering if it has been examined. If you take it for granded, fine, but in science it is odd to accept but not prove. In philosophy maybe. "According to one tradition Pythagoras of Croton coined the Greek word meaning 'lover of wisdom' (philosopher) to contrast with the Greek word meaning 'wise man'

"Perhaps there are studies, but I'm doubtful it's that simple." If it was simple it would've been known.


Otherwise, Doing thinking leads to comprehension by completing the easily guessed and ommited.

The mass of milk, water and other food eaten + the mass of oxygen taken up in respiration will equal the weight gain of the baby + the mass of waste (crap and urine) + the weight of water lost by respiration and sweating + CO2 expelled during respiration.

Mass will be conserved but you have to factor in all inputs and outputs...

There is NO reason to assume that nursing baby humans violate the law of conservation. What OTHER options are you providing that are a better explanation for mass gain then food/water in minus excrement out equate to mass gained.

Going out on a limb here: Is it possible our OP is searching for a way to measure some concept of a soul?

No it isn't. Conservation of mass is extremely well established as a theory it's entirely reasonable to assume it applies to anything other than approaching light speed conditions--such as a baby. Feel free to investigate on your own (or ask any parent after they've fed and removed a few hundred pounds of baby poo but is only ten or so pounds heavier). If science went back and retested every trivial well-founded assumption it would never progress. Furthermore, science doesn't prove things--it adds to the pile of evidence to support or not support hypotheses.
