This document discusses calculating magnification of drawings and images. It provides examples of calculating magnification by measuring the drawn/image size and actual size. Magnification is the ratio of drawn/image size to actual size. A scale bar can also be used to determine actual size and magnification, by measuring the scale bar in the image and calculating its magnification based on its known actual size.

The main purpose of the convex lens is to converge the light coming from an external source, and as a result, the light is focused on the other side of the lens

Ophthalmic Prisms: Prismatic Effects and Decentration
here we discuss about the ophthalmic prisms, the prismatic effects as caused by the decentration( moving the optical center away from the visual axis)
Magnification is a method of increasing the size of the image
so that enough of the retina is stimulated to send an impulse
through the optic nerve allowing an object to be perceived .

The accuracy of an instrument is the extent to which the reading it gives might be wrong. Accuracy is often quoted as a percentage of the full-scale deflection (f.s.d.) of the instrument.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
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.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
8. Length of ant = 10mm
Length of drawing = 25mm
Mag = 25mm
10mm
Mag X2.5
9. Mag X2.5
Ask yourself “does this sound about right?”
In this example we are saying the drawing is magnified X2.5
Or it is two and a half times bigger than the actual ant
And that seems about right!
10. If we draw something
smaller than it actually is
the magnification should
be a fraction
18. Next we calculate how much the image has been
magnified by seeing how much the scale bar is
magnified
100µm = 20mm
100µm = 20 000µm
The scale bar is magnified
20 000/100
=X200
19. What this means is the picture has been magnified
200 times
100µm = 20mm
100µm = 20 000µm
The scale bar is magnified
20 000/100
=X2000
20. Next we measure the cell we are interested in
100µm = 20mm
100µm = 20 000µm
The scale bar is magnified
20 000/100
=200times
The cell is 17mm
Or 17 000µm
21. Now we can find the actual length of the cell
100µm = 20mm
100µm = 20 000µm
The scale bar is magnified
20 000/100
=200times
Mag = image size/ actual size
Actual size = image size/mag
= 17000µm/200
= 85µm
