The telescope and the microscope both made of glass, amplified to see the heavens and the smallest micro-organism has led civilization out of the dark ages and allowed mankind to understand the human body, diseases, the solar system, and many other important discoveries. The importance of each of these incredible instruments cannot be explained in mere words. This paper has only touched the tip of the contributions made to mankind by brave men who using their instruments, advancing astronomy and medicine to unbelievable levels. As Victor Hugo, in Book 3 Chap. 3 of Les Miserables states, "Where the telescope ends, the microscope begins. Which of the two has the grander view?”
Just like the Perigordian and Aurignacian cultures the typical tools that were used in the Solutrean culture are burins, blade tools, end scrapers (Aggarwal). The Solutrean culture is known for having excellent crafted flint tools (Aggarwal). In the Solutrean culture the typical tools were thin and beautifully crafted laurel-leaf pointed tools, which resemble a leaf (O’Neil). As craftsmanship kept increasing shoulder point tools started to evolve (Aggarwal). Shoulder point tools resemble the laurel-leaf pointed tools, but the difference is one side of the shoulder point tool is restricted (Aggarwal). Laurel-leaf pointed tools and shoulder point tool could have been used in an immeasurable amount of ways. In order to have successful tools in the Solutrean culture, the person creating the tool has to master the pressure flaking
Microsocopy has been of prime importance in various fields in biology studies like microbiology, zoology, botany, biotechnology and various other feilds, owes it's existence to Antony Van Leeuwenhoek. In 1673 early microscope consisted of a bio cancave lens and in two metal plates. Over the years, microscopes have evolved from the simple, single-lens instrument of Leeuwenhoek, with a magnification of 300, to the present-day electron microscopes capable of magnifications greater than 250,000. The two important types of microscopes are light microscope and electron microscope.The former use visible light or ultraviolet rays to illuminate specimens. The different types of microscopy includes bright feild microscopy, dark feild, phase contrast and fluorescent microscopy. Fluorescent microscope use UV radiation whose wave length are shorter than those of visible light. Electron beams are used in electron microscope and also magnets.
The purpose for completing this lab was to observe how microscopes function. The invention & evolution of the microscope has been an ongoing process since the Middle Ages, when the first convex magnifying lenses were introduced. In 1590, the Jansen Brothers invented the first compound microscope (two or more lenses).However, Antony van Leevenwenhoek created the first “true” microscope, in 1665, with 300x magnification & unbelievable resolution. During the late 1700’s, the microscope was reinvented with 1500x magnification. The most recent advancement in microscopes is the electron microscope, which was invented in 1930. This particular model uses an electron beam, instead of light & 4,000,000x magnifications with incredible resolution.
The microscope and the general study of microbiology has helped shaped society and and has created many advances in the field of science. Through all history, the microscope evolved into a modern form, and still is the recipient of many upgrades and enhancements. One of the main beneficiaries of the works of the microscope is the medical field, with a closer look on microbiology, scientists are now able to predict viruses, prevent them, and even cure them. The microscope also provides insight into the lives of bacteria, how it forms, how it thrives, and provides us with a deeper understanding on how life came to be. The study and tool is also used to keep Earth as close to perfect as we found it, with many ecologists are working towards a clean green Earth. Overall, the microscope has been used all over the world to create deeper awareness of society and even life itself.
Most microscopes consist of twelve parts; the eyepiece lens, the tube, the arm, the base, the illuminator, the mirror, the stage, the turret, the objective lenses, the rack stop, the condenser lens and the iris. Every part of a microscope has a very important responsibility in order for people to see smaller things clearly. For example the eyepiece lens is what you look through to observe. An illuminator is a one hundred and ten volt light source that i...

There are many different types of alloys; some are so common that they carry on a life beyond their metal bases. For example, 65-90% of copper mixed with 10-35% of zinc create the well known alloy brass, which provides increased resistance to corrosion in things like instruments and
The trades of tin plate working continue to this day to make an important contribution to our everyday lives, to industry and to the economy. The trade of tinplate making covers both the manufacture of tinplate from...
Since it takes more energy to dig up and produce Aluminiun than any other metal, recycling not only avoids resources to be extracted from Earth, it also saves energy. 105 million Aluminium cans are thrown out every year and it is enough to build more than 70000 Boeing 737 Airplanes almost 10 times the number of 737’s build. Physically, Chemically and Mechanically aluminium is a metal like steel, brass, copper,
