Roger Joseph Boscovich (1711–1787) was a notable Croatian polymath, physicist, astronomer, philosopher, and mathematician. Born in Ragusa (present-day Dubrovnik, Croatia), he is best known for his foundational work in various scientific disciplines during the Enlightenment period. Boscovich is particularly recognized for his contributions to the field of atomic theory.
Francesco Maria Grimaldi (1618-1663) was an Italian scientist, physicist, and mathematician, best known for his contributions to the study of light and the phenomenon of diffraction. He is often credited with being one of the first to investigate the wave nature of light. His most notable work involved the observation and documentation of the bending of light waves around edges, which he called "diffraction.
Giovanni Battista Baliani (born in 1647 and died in 1712) was an Italian physicist and mathematician. He is known for his work in the field of fluid dynamics and for his investigations into the properties of air, including barometric pressure. Baliani conducted experiments that contributed to the understanding of vacuums and atmospheric pressure.
Paolo Casati is an Italian physicist and professor, noted for his work in the fields of nanoscience and photonics, particularly in the context of quantum optics and the manipulation of light at the nanoscale. He might be recognized for his research contributions, publications, and involvement in scientific communities.
Johannes Bosscha was a notable Dutch astronomer and physicist, best known for his contributions to the field of astronomy in the late 19th and early 20th centuries. He played a significant role in the establishment of astronomical research and education in the Netherlands and was particularly associated with the development of the Bosscha Observatory in Lembang, Indonesia, which was named in his honor. The observatory became an important center for astronomical studies in the region.
Giovanni Battista Beccaria (1738-1794) was an Italian philosopher, jurist, and criminologist, best known for his work in the field of criminal law and his contributions to the Enlightenment discourse on justice and punishment.
Floyd R. Watson may refer to a specific individual, but without more context, it’s difficult to determine exactly who you are asking about. Generally, Floyd R. Watson does not appear to be a widely recognized figure in history or popular culture as of my last training cut-off in October 2023. If you could provide more information or clarify the context around Floyd R. Watson—whether he's related to a specific field (like science, literature, etc.
Johann Josef Loschmidt (1821–1895) was an Austrian scientist known primarily for his contributions to chemistry and physical science. He is most renowned for his work in the field of gas theory. Loschmidt is particularly famous for calculating the size of molecules and atoms, which he did in the context of molecular gas theory.
In mathematics, particularly in the field of set theory and functions, the **codomain** refers to the set of all possible outputs of a function.
Wilhelm Karl Ritter von Haidinger (1795–1871) was an Austrian mineralogist and geologist known for his significant contributions to the field of mineralogy, particularly regarding the study of crystals and minerals. One of his notable achievements includes the identification and description of the mineral "Haidingerite," which is named in his honor. He also played a role in the development of crystallography and contributed to the understanding of the optical properties of minerals.
William Nicol (1790–1879) was a Scottish geologist and a notable figure in the field of geology during the 19th century. He is primarily known for his contributions to the study of mineralogy and geology, particularly through his work on polarized light and the invention of the Nicol prism. The Nicol prism, invented in 1828, is an optical device used to split light into its component colors, which allows for the study of minerals under polarized light.
Jean Baptiste Perrin (1870–1942) was a French physicist known for his work in the field of atomic physics. He is best recognized for his research on the nature of matter and his contributions to the experimental validation of the atomic theory. Perrin conducted experiments that provided evidence for the existence of atoms, particularly through studies of Brownian motion, which is the random movement of particles suspended in a fluid.
Eilhard Wiedemann (1876–1959) was a German physicist known for his contributions to the field of gas discharge physics and related areas. He is perhaps best recognized for his work on the properties of gases under electrical discharge and for his role in advancing the understanding of high-voltage engineering. Wiedemann is also associated with the Wiedemann-Franz law, which describes the relationship between electrical conductivity and thermal conductivity in metals.
Franz Melde, often referred to in the context of "Melde's experiment," is associated with a classical physics experiment conducted in the 19th century. The experiment demonstrates the principle of resonance and the behavior of standing waves on a stretched string. In the setup, a wire is clamped at both ends and can be set into vibration. By adjusting the tension in the wire or the frequency of the vibrations, one can observe standing waves forming at certain frequencies known as harmonic frequencies.
Georg Wilhelm Muncke was a notable figure in the field of dermatology, particularly known for his contributions to the understanding of skin diseases and conditions in the mid-20th century. He is often referenced in dermatological literature for his work on various skin disorders, although there may also be other contexts or interpretations depending on the specific field of interest.
Heinrich Rubens, often referred to in the context of scientific achievement, is known for his contributions to the field of physics, specifically in relation to the study of electromagnetic waves and spectroscopy. He is notably recognized for his work on the Rubens tube, a demonstration apparatus that visualizes sound waves by converting them into visible patterns of flame. This device can be used to illustrate the relationship between sound waves and pressure variations in gas.
Otto Lummer (1860–1925) was a German physicist known for his contributions to the fields of optics and photometry. He is particularly recognized for his work on the development of optical instruments and for his investigations into light and its properties. Lummer, along with his associate, made significant strides in the study of spectral lines and the precision of optical measurements.
Theodor Wulf is best known as a German physicist who gained recognition for his work in the field of high-altitude physics and for his experiments related to cosmic rays. He is perhaps most famous for his 1912 experiments which demonstrated that radiation intensity changes with altitude, providing early evidence for the existence of cosmic rays. Wulf is also associated with the "Wulf radiation" effect, which refers to the variations in radiation experienced at different altitudes.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
