The Invention Of The Electron Microscope By Ernst Ruska And Max Knoll

The Scientific Revolution was when modern science was essentially established, which came along with the major scientific discoveries took place at the time. Some major scientists that contributed to this major era include Nicholas Copernicus, Tycho Brahe, Galileo Galilei, and Isaac Newton. The scientific revolution took place following the Renaissance, from the mid-1500’s until about 1700. This revolution took place throughout Europe. This occurred because, following the Renaissance and the reformation, people became very curious and wanted to understand how the Earth worked. It was almost as if, being that this occurred after the reformation, that they wanted to either confirm or refute the church’s claims. The significance of the scientific revolution was one of great proportions, it changed mankind’s understanding the importance of science, and of how the Earth and solar system function.

The 1960s was a decade where many Americas found a new life and way of living, it was the time of the hippies, peace and love. It was also a time where many scientific and medical discoveries where made, these discoveries have improved our everyday lives up to the date. During the sixties technology advanced with satellites, video games, the Internet etc. and with these advances they have changed our life style. Without the advance of the internet imagine how we would be today, nowadays we use the internet for everything we do.

The Scientific Revolution was at its height during the sixteenth and seventeenth centuries with many supporters and critics of the works of scientists. It was the transition from the medieval, philosophical and religious perspective to a secular and rational perspective. One of the biggest debates that defined the Scientific Revolution was the debate over whether the universe was geocentric (with the earth at the center of the universe), or heliocentric (with the earth revolving around the sun). The works of these scientists was influenced by political leaders for their desire in power, the clash of ideas between religious leaders and institutions, and differentiation towards female scientists and unorganization in research. In all, each of these three parts of society contributed to the Scientific Revolution in very important ways.

Antonín Dvořák (1841–1904) was one of the most versatile and prolific composers of the nineteenth century, reaching into almost all genres of music from piano miniatures to comprehensively conceived vocal-orchestra compositions. His output encompasses nine symphonies and fifty-five other orchestral pieces, eleven opera, eleven works for chorus and orchestra, nine small choral works, thirty-five sets of songs and duets, fifty-five chamber works for various combinations of instruments, and thirty-two sets of short pieces for piano. In each of these areas he created works that can be considered masterpieces in their genre.

Isaac H. is a well-developed African American that experienced the Great Migration in his lifetime. Growing up poor, Isaac had nine siblings and family throughout the United States. Isaac’s Aunt specifically lived in Milwaukee, Wisconsin, and invited Isaac to experience the north at an early age by working there during his summers.The Great Migration was a movement that changed Isaac H.’s life because his family moved to the north and created a foundation for him.This foundation, along with Isaac’s experience, was established by the Blacks who took a risk and moved to the North without a guarantee that there was anything for them .This risk was in the minds of almost 6 million African Americans and they all made a choice that resulted in

Green Fluorescent Protein, produced by the bioluminescent jellyfish Aequorea victoria, is a protein that fluoresces green under ultraviolet light. Since its discovery, properties of the protein have been improved by mutations in the gene resulting in the expansion of its spectrum, which now contains brighter variants and multiple different colors. GFP is used in a wide variety of applications and technologies. Its many different applications have contributed greatly, and continue to do so, in numerous fields of study including, but not limited to, cellular and molecular biology, microbiology, biotechnology, and medicine.

The GFP gene allows for the bacteria to have the information to produce the fluorescent color. However, this is not enabled by default. In order for it to be activated, it must be induced by the arabinose. Once arabinose is introduced, the protein can be

During the early 1940’s atomic science had just began to mature. Many people were exploring the powerful mystery of the atom. Two of those people were Eugene Booth and John Dunning, who, in 1941, synthesized uranium-235. Immense scientific growth followed their contribution, since it allowed for nuclear fission (Griffith). In the years following this discovery, nuclear science took a turn. Once only used as a constructive power source, atoms began being explored for their destructive power. In 1942 the United States government funded the Manhattan Project that sole goal was to develop a nuclear bomb. The initiator for this endeavor was surprisingly the famous scientist Albert Einstein. He wrote to Franklin D. Roosevelt , and tipped him off

Scientists can study and manipulate genes by using precisely engineered plasmids, According to ADDGENE, a nonprofit plasmid repository, plasmids “have become possibly the most ubiquitous tools in the molecular biologist’s toolbox” (“What Is a Plasmid?”). In this experiment, we will use pGLO to genetically transform the bacteria E. coli. pGLO is a genetically engineered plasmid that carries the reporter genes for both green fluorescent proteins (GFP) and the ampicillin resistance. GFP, a protein typically found in the bioluminescent jellyfish Aequorea victoria, exhibits a bright green fluorescence in the presence of blue to UV wavelengths (Mecham); the protein absorbs UV light from the sun and emits it as a lower energy green light, exemplifying the second law of

The modern synthesis is the explanation for the evolution of continuously varying traits that combines the theory and empirical evidence of both Mendelian genetics and Darwinism (Boyd and Silk 2015: glossary A9). Science in the 1800’s had made some fantastic new discoveries. A man named Charles Darwin and Gregor Mendel. Darwin managed to figure out how natural selection works and why species tend to change over time. Darwin’s theory of the three postulates helped explain how species change. Mendel on the other hand was a scientist that studied plants and while studying plants had figured out how inheritance works. When Mendel figured out how inheritance works on pea plants the same process could work on how humans were evolved.

An Atom is the the basic building block of all matter. Atoms are made up of Particles, called: Protons, neutrons and Electrons. Protons carry a positive charge, the neutron carry 's a neutral charge and the electron carry’s a negative charge. The Atom has two main parts the Nucleus and the Electron Shell. The Nucleus contains the Protons and Neutrons. The electron Shell Contains the The electrons.

During the cold winter of 1895, a German scientist by the name of Wilhelm Conrad Roentgen was working with a cathode-ray tube when he noticed nearby crystals were glowing. When Roentgen reached for the crystals he was amazed when the shadow cast on the crystal was not of his whole hand, but just his bones. Roentgen covered the tube with heavy black paper and saw that the crystals still glowed and the shadow of his hand bones still shown through, he then determined that a new ray was being emitted that could penetrate through thick materials. (1.) He later found that the rays could pass through most anything, but would cast a shadow of solid objects; these shadows could then be captured on film. Among the solid objects Roentgen shot with

It is often used in conjunction with epifluorescence and involves the use of long wavelengths to excite fluorophores, which are fluorescent chemical compounds that light up upon excitation, in the tissue of interest (Mempel, 2004). These techniques have shed light on the crawling at a molecular level, including the importance of integrins.

Karl Landsteiner, the brilliant and skillful scientist from early twentieth century Vienna, is one of the most influential persons in modern science. He has had a major impact on today’s society, as a result of his discovery of the blood groups and of the Rhesus (Rh) Factor. His work continues to have a huge impact on today’s society in the areas of blood transfusions and the effect of the rhesus factor during pregnancy and childbirth. He has also made many other contributions to science, such as in the areas of the immunology of syphilis and work with transfusion of poliomyelitis. His works eventually earned him a Nobel Prize as well as allowed him to publish papers on his findings.

The electron microscope has become one of the most widely utilized instruments for materials characterization. An electron microscope is a scientific instrument that allows us to “see” objects so small that they cannot be seen in any other way. (CITE) Electron microscopes have allowed scientists to see individual molecules and atoms for the first time.
