Robert Hooke (; 18 July 1635 – 3 March 1703) 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 wri…

A microscope is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using a microscope. Microscopic means being invisible to the eye unless aided by a microscope. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through or onto a sample in its optical path, by detecting photon emissions from a sample, or by scanning across and a short distance from the surface of a sample using a probe. The most common…

Critical Focus | The Incredible, Invisible World of Robert Hooke. It is time to celebrate. The first popular science book in the world is 350 years old this year — and it was a volume devoted to the world of the microscope, aptly titled Micrographia. Our modern era is dominated by the indulgent irrelevance of fairytale physics that no one understands, so a hands-on, relevant subject like microscopy attracts little popular interest. Back in the intellectual dynamism of the 17th century, microscopy was a major talking point. The book’s author was a multi-talented pioneer named Robert Hooke. What a series of paradoxes he poses. Hooke was born on the tiny Isle of Wight, yet became one of the gr…

The microscopic scale (from Ancient Greek μικρός (mikrós) 'small' and σκοπέω (skopéō) 'to look (at); examine, inspect') is the scale of objects and events smaller than those that can easily be seen by the naked eye, requiring a lens or microscope to see them clearly. In physics, the microscopic scale is sometimes regarded as the scale between the macroscopic scale and the quantum scale. Microscopic units and measurements are used to classify and describe very small objects. One common microscopic length scale unit is the micrometre (also called a micron) (symbol: μm), which is one millionth of a metre.

The germ theory of disease is the currently accepted scientific theory explaining the cause of infectious diseases. It states that microorganisms known as pathogens or "germs" can cause disease. These small organisms, which are too small to be seen without magnification, invade animals, plants, and even bacteria. Their growth and reproduction within their hosts can cause disease. "Germ" refers not just to bacteria but to any type of microorganism, such as protists or fungi, or other pathogens, including parasites, viruses, prions, or viroids. Even when a pathogen is the principal cause of a disease, environmental and hereditary factors often influence the severity of the disease, and whethe…

Bioarchitectonic Nanophotonics by Replication and Systolic Miniaturization of Natural Forms.. The mimesis of biological mechanisms by artificial devices constitutes the modern, rapidly expanding, multidisciplinary biomimetics sector. In the broader bioinspiration perspective, however, bioarchitectures may perform independent functions without necessarily mimicking their biological generators. In this paper, we explore such Bioarchitectonic notions and demonstrate three-dimensional photonics by the exact replication of insect organs using ultra-porous silica aerogels. The subsequent conformal systolic transformation yields their miniaturized affine 'clones' having higher mass density and ref…

The Schema and Organization of the Cell: An Introduction to Ernst Brücke's Die Elementarorganismen (1861).. Ernst Brücke's 1861 essay Die Elementarorganismen has often been cited as a watershed in the history of physiology as well as in the history of cell theory. In its time it was widely read as a reform of animal cell theory, shifting the concept of the cell away from Schleiden and Schwann's original cell schema of a membranous vesicle with a nucleus, and towards the protoplasm theory that had developed in botany, centered on the cell's living contents. It was also notorious for its arguments against the necessity of both the nucleus and the cell membrane. An English translation of "The…

Core Concepts for Early Childhood Microbiology Education.. This article explores how microbiology can be meaningfully integrated into science education for preschoolers, children under 6 years old. Current research shows that the early years represent a critical period for scientific learning. Microbiology offers a unique opportunity to engage children in curiosity, and reflection by connecting the invisible microbial world with their everyday experiences. Its introduction at a young age supports the development of scientific thinking skills and helps correct prevalent misconceptions about microorganisms that often continue into adulthood. To overcome these misunderstandings, we designed an…

Storytelling of Myocardial Biopsy.. A biopsy involves the removal of a piece or an entire organ from a living patient. The former began with open heart surgery (surgical pathology) and the latter with the recipient heart in cardiac transplantation. Transvenous or transarterial catheterization is the current procedure to performed endomyocardial biopsy with bioptome from the ventricles. This manoeuvre was first carried out by Werner Forssmann through a urological catheter in 1929, which he introduced into his radial left vein until it reached the RV. Then, in London in 1974, Richardson invented a new technique with a catheter via the right femoral vein, which he applied with success in patie…

Antonie van Leeuwenhoek and the dawn of microscopic observation: a narrative review from Delft's lens to the modern microscope.. Antonie van Leeuwenhoek (1632-1723) transformed observation into science through the power of a single handmade lens. His work emerged from the visual culture of seventeenth-century Delft, where craftsmanship, optics, and artistic precision intersected. While Robert Hooke's compound microscope introduced the idea of microscopic visualization, Leeuwenhoek's single-lens instruments achieved far superior magnification and resolution by minimizing optical interfaces. Using these deceptively simple devices, he documented the first observations of free-living microorgan…
