Step-by-step explanation:

The great temples and monuments of ancient Egypt continue to fascinate and amaze people in the modern day. The sheer size and scope of structures like the Great Pyramid at Giza or the Temple of Amun at Karnak or the Colossi of Memnon are literally awe-inspiring and naturally encourage questions regarding how they were built. All across the Egyptian landscape rise immense structures, thousands of years old, which have given rise to many different theories as to their construction. While a number of very significant questions remain unanswered, the simplest explanation for many can be found in ancient Egyptian inscriptions, texts, wall paintings, tomb inscriptions, art, and artifacts: the ancient Egyptians had an extraordinary command of science and technology.

they made advances in almost every sphere of knowledge from the manufacture of simple household goods to beer brewing, engineering and construction, to agriculture and architecture, medicine, astronomy, art and literature.

Science in simple words can be defined as a set of facts based on observations and experimentation. One of the foundation stone of science is that the results can be replicated under same test conditions. These results which are replicable constitutes a theory to explain things or phenomena and can only be replaced by a newer or better theory once a new set of facts overturns the earlier theory on its head.

In ancient science where the opportunities of repeated testing was very limited, whatever a few learned men said became science. For example, Ptolemy said that earth is the center of the universe and everyone started believing that. ( I am not hinting that Ptolemy was a soothsayer and others were his blind followers. I simply want to say that his observations were based on a few facts available to him). Later on, a newer renaissance period came in to existence with a counter set of facts.

Similarly, the ancient science was in some ways not very precise. For example, if an ancient physician has identified a herb for treating certain disease, that will become a part of scientific knowledge of that time. On the other hand, modern science will be more precise. Its will ask more questions on mechanisms involved, the identification of exact chemical which is acting on the disease and so forth.

Overall, the difference in modern science and ancient science was in the level of preciseness and the easier acceptability of facts as science with less of scrutiny.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
