You might be surprised to find, however, that the first seismometer was invented in China in 132 AD by a Chinese astronomer, mathematician, engineer, and inventor called Zhang Heng. The instrument was said to resemble a wine jar six feet in diameter, with eight dragons positioned face down along the outside of the barrel, marking the primary compass directions. In each dragon’s mouth was a small bronze ball. Beneath the dragons sat eight bronze toads, with their broad mouths gaping to receive the balls. When the instrument sensed an incoming seismic wave, one of the balls would drop and the sound would alert observers to the earthquake, giving a rough indication of the earthquake’s direction of origin. The device is said to have been very accurate and could detect earthquakes from afar, and did not rely on shaking or movement in the location where the instrument was positioned. The first ever earthquake recorded by this seismograph was supposedly somewhere in the east. Days later, a rider from there reported this earthquake. Moreover, it had the most wicked ornaments. They don’t make scientific instruments like they used to! Of course, the insides of the seismometer was filled with a sensing mechanism of some sort, the contents of which have been lost in time. In all likelihood, a simple or inverted pendulum was employed, according to experts.
Answer:
here are some reason:
maps were once drawn on clay tablets carved on the ground and drawn on mark..... now maps are obviously on paper.
also maps in the earliest ages were not accurate because mapmakers didn't know the "correct" knowledge.... now on maps we know the correct knowledge.
also didn't know mathematics and the correct knowledge and he sometimes left empty spaces and warning because honestly he didn't know what the heck what was there.....

The locating that IQ scores have increased dramatically during the last century is referred to as the Flynn impact.
The Flynn effect refers to a secular growth in population intelligence quotient (IQ) located at some point of the twentieth century (1–four). The modifications were rapid, with measured intelligence normally growing around three IQ factors per decade.
An instance of the Flynn effect is IQ rankings elevated by using 13.8 factors from 1932 to 1978. A similar price of growth was observed from 1972 to 2006.

Answer: Three effects that European imperialism had on Africa included a more structured political system with an organized government, the development of industrial technology and the idea of nationalism, which led to wars and revolutions later on.Europeans changed the economy from a model of producing foods for need to mainly the production of cash crops. All crops produced by Africans were exported and prices were set by the colonies. Africans were not allowed to grow these cash crops to benefit themselves.Imperialism adversely affected the colonies. Under foreign rule, native culture and industry were destroyed. Imported goods wiped out local craft industries. By using colonies as sources of raw materials and markets for manufactured goods, colonial powers held back the colonies from developing industries.
hope this helps have a nice day❤️
