The most well known application of this theory is the use of a curve on a graph to represent the motion of an object, which could then be defined by a mathematical equation that would grant insight into the forces at work on the object. Further progress in mathematics was made by Oxford professor John Wallis.
The amount of time it takes for food to pass through your intestines depends on the type of food you have eaten, among other things. In general, it can take 24 to 44 hours from the time you eat food to the time it leaves your body as waste. The amount of food you eat and whether it is solid or liquid will affect how long it takes to pass from the stomach to the small intestine and from there to your colon.
so generally, food leaves the stomach about four hours after you eat it. it really depends on how big of a meal you've eaten, because the duodenum can only take in a small amount at a time for calorie absorption (i believe, on average, every 30 minutes or so it opens up to take in another handful of chyme). but, of course, digestion continues after food leaves the stomach. it goes on to the rest of the small intestine for further nutrient absorbtion, and then to the large intestine for water absorbtion. under normal circumstances, it can take 24-48 hours for a meal to fully leave your body.
