He had studied and worked in British textile mills for a number of years and immigrated to the United States, despite restrictions against it, to try his luck with U.S. manufacturers who ...

But the rate of progress is also dependent on other factors, such as the number of researchers, the level of funding, and advances in technology. Thus the number of new species of mammals discovered between the late 1700s and late 1800s followed grew exponentially before leveling off in the 1900s; the general shape is known as the logistic curve .
