The document discusses the history and development of microscopy from the 14th century to the late 19th century. It describes how early microscopes used simple lenses and had magnifications between 10x-80x, while Leeuwenhoek achieved up to 300x magnification. The compound microscope was developed in the mid-17th century, improving detail visibility. Later advances included achromatic lenses, oil immersion, and condensers to further enhance resolution. Key optical principles such as refractive index and the factors affecting resolution and its relationship with magnification are also summarized.

DARK FIELD MICROSCOPY by SIVASANGARI SHANMUGAM
Dark-field microscopy is ideally used to illuminate unstained samples causing them to appear brightly lit against a dark background.

BRIGHT FIELD MICROSCOPY by SIVASANGARI SHANMUGAM

A Microscope is an instrument for viewing objects that are too small to be seen by the naked/ unaided eyes.
In Greek micron= small
skopien=to look at
The science of investigating small object using such an instrument is called microscopy
The term microscopic means minute or very small, not visible with the eye unless aided by a microscope
From ancient times, man wanted to see things for smaller than could be perceived with the naked eye.
This led to the construction in the 16th century, of a magnifier composed of a single convex lens, and this in turn led to the eventual development of the microscope.
The most famous early pioneers in the history of microscope are Digges of England and Hans & Zcharias Janssen of Holland
It was Antony Van Leeuwenhoek who became the man to make and use a real microscope.
Leeuwenhoek microscope was called as single lens microscope because it had convex lens attached to metal holder and was focused using screws
this presentation deals with the introduction of some of the commonly used optical microscopes in forensic labs; compound microscope, stereoscopic microscope, comparison microscope, fluorescence microscope and polarized microscope.

Microscope is an instrument used to observe the objects which are not visible to our naked eye. Faber (1625) used the term microscope and it is derived from two Greek words namely, Mikros= Small ; Skopian= To See. The Dutch spectacle maker, Zaccharias Janssen (1590) discovered the first microscope, he found that two hand lenses could greatly enlarge the image. His lenses gave 50-100X magnification; this was the beginning of the compound microscope. Robert Hooke (1668) invented compound microscope with two kinds of magnifying lens systems namely objective lens system and ocular lens system. He obtained 200X magnification He observed and described the microscopic structure of cork cells in his ‘’Micrographia’’. Antony Van Leeuwenhoek (1667) who was wrongly credited as inventor of compound microscope actually invented simple microscope by using convex lenses of high magnification power up to 300X.
The microscope has evolved a lot from the time of Leeuwenhoek. This presentation gives a brief overview about the types of microscope their principle of function and application.
Microscope and Microscopy
Principal , Function & Difference of various types of Light & Electron microscope.Microscopy is the technical field of using microscopes to view samples & objects that cannot be seen with the unaided eye (objects that are not within the resolution range of the normal eye).
Microscopists explore the relationships between structures & properties for a very wide variety of materials ranging from soft to very hard, from inanimate materials to living organisms, in order to better understand it. Zachariaz Janssen 1585 Robert Hooks 1665

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

47. How Does a Microscope Work? the eye the image the specimen Each lens magnifies the image, increasing its overall size A lens is a bi-convex disk that bends light The farther the light rays are bent, the larger the image appears The bent rays produces an image
48. How Does a Microscope Work? the eye the image the specimen The image is always seen upside down and backwards from its actual position
