In beaker A, you can see the oil and the water existing in separate layers. In beaker B, the beaker is shaken up, which disperses the oil in the water temporarily. When you set it back down again, however, (beaker C), you can see that it separates again. In beaker D, we added an emulsifier.
Why PI Was Created. PI was created to provide high school students a place where they can create their invention ideas. Too often, students conceive ideas that can change the world. Due to insufficient support and guidance, most high school students cannot bring their invention ideas to life.
Pi, given its name after the Greek letter, was not named so by the Greeks, nor did they invent the concept. It is true that the Ancient Egyptians first discovered the number, and there are references to a number in an Egyptian scroll dating to 1650 BCE.rchimedes approximated it in about 200 BCE in fraction form, since the Greeks did not yet use decimals. He expressed pi as a fraction similar to 3 1/7, which is in decimals approximately 3.14. Mathematicians and scientists left pi at Archimedesâ calculation for centuries.
