Microtechnology is technology whose features have dimensions of the order of one micrometre (one millionth of a metre, or 10 −6 metre, or 1μm). [1] It focuses on physical and chemical processes as well as the production or manipulation of structures with one-micrometre magnitude.
The early development of microtechnique in botany is closely related to that in zoology. Zoological and botanical discoveries are adopted by both zoologists and botanists. [5] Since Hooke discovered cells, microtechnique had also developed with the emergence of early microscopes. Microtechnique then had advanced over the period of 1800–1875. [6]
The last of the non-avian dinosaurs died 66 million years ago in the course of the Cretaceous–Paleogene extinction event, whereas the earliest members of the genus Homo (humans) evolved between 2.3 and 2.4 million years ago. This places a 63-million-year expanse of time between the last non-avian dinosaurs and the earliest humans.
Mathematics is essential in the natural sciences, engineering, medicine, finance, computer science, and the social sciences. Although mathematics is extensively used for modeling phenomena, the fundamental truths of mathematics are independent of any scientific experimentation.
Śrīdhara wrote two extant mathematical treatises. The first, Pāṭīgaṇita, also called Bṛhat-Pāṭi ("Bigger Pāṭi") and Navaśatī ("Having 900"), extensively covered the practical mathematics of the time including arithmetic and mensuration (the part of geometry concerned with calculating sizes, lengths, areas, and volumes). [1]
The History of Mathematics consists of seven chapters, [1] featuring many case studies. [2] [3] Its first, "Mathematics: myth and history", gives a case study of the history of Fermat's Last Theorem and of Wiles's proof of Fermat's Last Theorem, [4] making a case that the proper understanding of this history should go beyond a chronicle of individual mathematicians and their accomplishments ...
Dylan Andrews scored 21 points, Tyler Bilodeau added 18 and No. UCLA extended its winning streak to nine games with a 111-75 victory over Prairie View A&M on Tuesday night. Eric Dailey scored 14 ...
Thabit ibn Qurra: the only surviving fragment of his original work contains a chapter on the solution and properties of cubic equations. He also generalized the Pythagorean theorem , and discovered the theorem by which pairs of amicable numbers can be found, (i.e., two numbers such that each is the sum of the proper divisors of the other).
