Robert Hooke
English scientist, 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 young 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 by 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 Society and from 1662, he was its first Curator of Experiments. From 1665 to 1703, he was also Professor of Geometry at Gresham College. Hooke began his scientific career as an assistant to the physical scientist Robert Boyle. Hooke built the vacuum pumps that were used in Boyle's experiments on gas law a

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 the membrane both in and out of the cell.
Most cells also contain genetic material in the form of deoxyribonucleic acid (DNA). In eukaryotes, DNA is stored within a subcellular compartment known as the nucleus.
In prokaryotes, there are no intracellular membranes, and the DNA is located in the cy
