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.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
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.

5. What is a Charge ?
• Charge is the inherent property of matter that feels force
of attraction out repulsion due to excess or deficiency of
electrons.
• It is of 2 types :
A. Positive Charge (Due to electron deficiency)
B. Negative Charge (Due to excess of electrons)
• Its S.I. unit is Coulombs denoted by ‘C’.
• It is detected and measured using a device called
Electroscope.
9. Properties of Charge
• The total charge of the universe is conserved i.e. constant
• Like Charges attract each other and unlike charges repel
each other
• Charges are additive in nature
• Charges are always quantized i.e. Q = n x e
where q = charge,
n = no. of electrons
e = charge on one electron i.e. 1.67 x 10-19 C
• Charge is relativistically constant
11. Methods of Charging
• Charging by Conduction
When an uncharged body is brought into contact
(touched) with an charged body then the charge or
electrons are transferred from the charged body to the
uncharged body. This charges the uncharged body.
12. Methods of Charging
• Charging by Induction
In the induction process, a charged object is brought
near but not touched to a neutral conducting object.
The presence of a charged object near a neutral
conductor will polarize the charge within the
conductor.
14. What is Electricity ?
• Electricity is a form of a energy that can be easily
changed to many other forms.
• It can also be defined as flow of electrons in a
circuit.
16. Electric Current
• It is the rate of flow of electric charge (or electrons)
through a conductor i.e.
I = Q/t = ne/t where I stands for current
• It is a scalar quantity
• Its S.I. unit is coulomb per second or amperes (A)
• It is measured by a device called Ammeter
• Its direction is taken opposite to the flow of electrons
• It flows as a result of potential difference across the
ends of a conductor
18. Electric Field
• It is the 3 dimensional space around a charge in
which the force of attraction or repulsion can be felt.
Electric Field Intensity
• It is the force experienced by a unit positive charge
when placed in a magnetic field
• It is denoted by ‘E’
• Its S.I. unit is newton per coulomb (N/C)
• It is a vector quantity
20. Electric Potential
• It is the amount of work done in bringing a unit
positive charge from infinity to a given point in the
electric field.
• It is a scalar quantity
• Its S.I. unit is joules per coulomb or volts (V)
21. Potential Difference
• It is the amount of work done in bringing a unit positive
charge from one point to another point in an electric field.
• It is a scalar quantity
• Its S.I. unit is joules per coulomb or volts (V)
• It is responsible for the flow of current in a conductor.
• Measured by a device called Voltmeter.
.∞
B. A.
23. Ohm’s Law
• It was stated by Georg Simon Ohm
• It states that at constant physical conditions like temperature
are kept constant then the amount of current flowing
through a conductor is directly proportional to the potential
difference across its ends i.e.
I α V
V = IR where R is constant called Resistance
• According to this law conductors are divide into -
1. Ohmic conductors (follow ohm’s law)
2. Non- ohmic conductors (do not follow ohm’s law)
26. Resistance
• It is defined as the hindrance to the flow of current
• It is the ratio of potential difference to current i.e.
R = V/I
• Its S.I. unit is volts per ampere or Ohm (denoted by Ω)
• Reciprocal or resistance is called Conductance (C) .
S.I. unit Ohm-1 i.e. Ω-1
27. Factors affecting Resistance
• R α Length (l) ……(i)
• R α 1/Area of cross section of conductor (A) ………(ii)
From (i), (ii) and (iii) we get
R α l/A
R = ρl/A where constant “ρ” is the specific resistance of the
conductor
28. Specific Resistance
• Specific resistance is the resistance of a conductor of unit
length and unit cross sectional area i.e.
if l = 1 m and A = 1 m2 then R = ρ
• It depends on material of the conductor
• Denoted by rho i.e. “ρ”
• S.I. unit is Ohm metre (Ωm)
• Ρ α Temperature of the conductor
• Also known as Resistivity
30. Fixed Resistors Variable resistance or Rheostat
Types of Resistances
Fixed Resistances: Their value does not change under
constant physical conditions. They are set at a particular
value
Variable Resistances: Their resistance can be easily
changed by changing area of cross section and length
32. Electric Circuit
• A closed path in which electric current can flow is called an
electric circuit
• There are 2 types of circuits –
1. Open Circuit: No current flows
2. Closed Circuit: Current flows continuously
Open
circuit
Closed
circuit
35. Ammeter
It must be connected in series in the circuit.
Positive side of ammeter must be connected nearest
to the positive terminal of the battery (electric cell),
and vice versa.
36. Voltmeter
Voltmeters must be connected in parallel to the
circuit.
The positive side of voltmeter is connected to the
positive terminal of the cell, and vice versa.
39. Resistance in Series
• When two (or more) resistors are connected end to end
consecutively, they are said to be connected in series.
• When a number of resistors connected in series are joined
to the terminal of a battery, then each resistance has a
different potential difference across its ends (which
depends on the value of resistance). But the total
potential difference across all the ends of all the resistors
in series is equal.
• When a number of resistors are connected in series, then
the same current flows through each resistance
40. Resistance in Series
• The figure shows three resistances R1,R2,R3 connected in series. Now
suppose potential difference across resistance R1 is V1 , R2 is V2 and
R3 is V3. Let potential difference across battery be V, then :
V = V1+V2+V3.
Applying Ohm’s law to the whole circuit : V = IR. ………..(1)
Applying Ohm’s law to the three resistors separately, we get:
V1 = I x R1. ………………….. (2)
V2 = I x R2. ………………….. (3)
V3 = I x R3. ………………….. (4)
Substituting (2), (3), (4) in (1)
IR = IR1 + IR2+ IR3
OR, IR= I (R1+R2+R3)
Or, R = R1+R2+R3 .
Therefore we conclude that the sum total resistance in a series resistance
connection is equal to the sum of all the resistances.
41. Resistance in Parallel
• When two (or more) resistors are connected between the same
points, they are said to be connected in parallel.
• When a number of resistance are connected in parallel, then the
potential difference across each resistance is same which is equal
to the voltage of battery applied.
• Different amounts of current flows through each resistance (which
depend on the value of resistance). But the current flowing through
each parallel resistance, taken together, is equal to the current
flowing in the circuit as a whole. Thus, when a number of
resistance are connected in parallel, then the sum of current
flowing through all the resistances is equal to the total current
flowing in the circuit.
42. Resistance in Parallel
• The figure shows three resistances R1,R2,R3 connected in series. Now
suppose currant across resistance R1 is I1 , R2 is I2 and R3 is I3. Let
total current in the circuit be I, then:
I = I1+I2+I3.
Applying Ohm’s law to the whole circuit : I = V/R. ………..(1)
Applying Ohm’s law to the three resistors separately, we get:
I1 = V / R1. ………………….. (2)
I2 = V / R2. ………………….. (3)
I3 = V / R3. ………………….. (4)
Substituting (2), (3), (4) in (1)
V/R = V/R1 + V/R2+ V/R3
OR, V/R= V (1/R1 +1/R2 + 1/R3)
Or, 1/R = 1/R1+1/R2+1/R3 .
Therefore we conclude that the sum total resistance in a parallel
resistance connection is equal to the sum of reciprocal of all the
resistances.
