Final answer:
In 3000 BC, the Sumerians made significant technological advances including the invention of bronze, the wheel, irrigation techniques, and a sophisticated mathematical system.
Step-by-step explanation:
The year 3000 BC was a time of significant technological innovation, especially within the region of Mesopotamia, known for the early Sumerian civilization. During this period, the process for manufacturing bronze was developed, marking the onset of the Bronze Age and leading to bronze replacing stone as the primary material for tools and weapons. Alongside this metallurgical advancement, key agricultural tools such as the plow were developed, revolutionizing farming practices. Moreover, the invention of the wheel and the development of irrigation techniques allowed for the growth of cities and advancement of civilizations.
In the realm of science and mathematics, the Sumerians were quite progressive. They developed a complex mathematical system, including the concepts of sixty, ten, and one, which had varied applications including in their system of timekeeping. In terms of engineering, they are credited with mapping the movement of stars and devising the use of 360 degrees for measuring angles in geometry. These advancements in science and mathematics were critical to the growth of Mesopotamian civilizations and influenced later technological developments.
