The document discusses two types of waves: transverse waves and longitudinal waves. Transverse waves have energy that moves perpendicular to the direction of the wave. Examples include light and water waves. Longitudinal waves have energy that moves parallel to the direction of the wave and require a medium, like sound waves. Key characteristics of both waves include wavelength, frequency, and amplitude. The document also provides diagrams and videos to illustrate these two wave types.

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”.
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.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
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.

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.
2. Key Objectives:Key Objectives:
Investigate and understand the nature and
describe the characteristics of two types
of waves.
– Transverse Waves
– Longitudinal Waves
http://www.youtube.com/watch?
v=27a26e2CnuM
Model, label and draw diagrams of each.
4. Wave
A disturbance that
carries energy away
from its source
through matter or
empty space.
Three categories:
– Mechanical Waves
– Electromagnetic
Waves
– Matter Waves
5. Transverse Wave
A type of wave that
can travel through
both a medium or
empty space.
The energy moves
perpendicular to the
direction of the
wave.
– Light
– Water
6. Longitudinal Wave
A type of wave that
must travel through
a medium.
The energy moves
parallel to the
direction of the wave
– Sound
9. Frequency
The number of
waves counted in a
specific period of
time. (per second)
– Measured in Hertz
(Hz)
10. Amplitude
In a transverse wave:
The height or depth or
difference from the
rest point to the peak
of a wave
In a longitudinal wave:
The density/thickness
of the compression
17. Essential Learnings
All waves exhibit certain
characteristics
– Wavelength refers to the length of a wave
or distance between two identical points
on a wave (Length)
– Frequency refers to the amount of waves
in a period of time (Speed)
– Amplitude refers to the size of the energy
wave (Strength)
18. Essential Learnings
Wavelength is inversely
proportional to frequency.
– Wavelength increases Frequency
decreases
– Frequency increases Wavelength
decreases
19. Essential Learnings
Transverse Waves
– Energy travels perpendicular to the
wave
– Do not require a medium
– Amplitude is the distance from the
rest position to the crest or trough of
the wave.
– Light travels in Transverse Waves
20. Essential Learnings
Longitudinal Waves
– Energy travels parallel to the wave
– The portion of this wave where it is
crowded together is called the
compression
– The portion where the space
between compressions is greatest is
called the rarefaction.
21. Essential Learnings
Longitudinal Waves
– Requires a medium
– Wavelength is the distance from one
compression to the next compression
of the wave.
– Sound being produced by vibrations
travels in Longitudinal Waves
