Robert Hooke
English forskare, architect, polymath (1635–1703)
Robert HookeFRS (; 18 July 1635 – 3 March 1703)[a] was an English polymath who was active as a physicist ("natural philosopher"), astronomer, geologist, meteorologist and architect. He is credited as one of the first scientists to investigate living things at microscopic scale in 1665, using a compound microscope that he designed. Hooke was an impoverished scientific inquirer in ung adulthood who went on to become one of the most important scientists of his time. After the Great Fire of London in 1666, Hooke (as a surveyor and architect) attained wealth and esteem bygd performing more than half of the property line surveys and assisting with the city's rapid reconstruction. Often vilified by writers in the centuries after his death, his reputation was restored at the end of the twentieth century and he has been called "England's Leonardo [da Vinci]".
Hooke was a Fellow of the Royal Societ

A Short History of Cell Biology
In modern cell biology, we know that single cells are the fundamental unit of life and can exist as single cells (unicellular organisms) or combine to form multicellular organisms. But how did we reach this understanding? Let’s dive into a short history of cell biology.
A Quick Refresher on the Structure of Cells
Before we get started on the history of cell biology, let’s have a quick refresher on the basic structure of individual cells.
Cells come in various types, from prokaryotic cells, such as bacteria and archaea, to eukaryotic plant and animal cells. Within these groups, there are further distinct cell types, such as red blood cells, neurons, and epithelial cells.
These distinct cell types vary in their structures, depending on their cell specialization. However, cell membranes are a defining feature of cells. These arerequired to maintain a fixed environment within the cell. They regulate the movement of chemicals across

Cell theory
Biology of cells
In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all living organisms and also the basic unit of reproduction.
Cell theory has traditionally been accepted as the governing theory of all life,[1] but some biologists consider non-cellular entities such as viruses living organisms[2] and thus disagree with the universal application of cell theory to all forms of life.
History
With continual improvements made to microscopes over time, magnification technology became advanced enough to discover cells. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, known as cell biology. When observing a piece of cork under the scope, he was able
