Describe and contrast allopatric speciation and sympatric speciation..pdf
Describe and contrast allopatric speciation and sympatric speciation. Which is more common?
How do they typically take place? Outline the steps/process of each. Give a least one example of
each.
Solution
5).
Allopatric speciation or geographic speciation is speciation that occurs while biological
populations of the same species become vicariant. For instance, adaptive radiation, as observed
by Charles Darwin in Galapagos finches, is a consequence of allopatric speciation in the midst of
island populations.
The mechanism of adaptive radiation is known as allopatric speciation, in which one species in
particular population differs from all other species (isolated species) and genetic exchange is also
prevented among these species. Physical barriers such as a mountain range or long waterways
may makes impossible for them to mate. So, these isolated species develop or evolve according
to their habitat, because their gene modifications go in that direction (natural selection!).
Disruptive selection is one of the main driving forces of sympatric speciation. Sympatric
speciation is different and perhaps it does not exist. It occurs when there are no physical barriers
that prevent species to mate together. The occurrence of speciation may be depends on
availability of different food sources and existence of different shelters..

Write down the complex potential for a source of strength m locat.pdf
Write down the complex potential for a source of strength m located at
z=ih and a source of strength m located at z= -ih. Show that the real
axis is a streamline in the resulting flow field, and so deduce that the
complex potential for the two sources is also the complex potential for a
flat plate located along y= 0 with a source of strength m located a distance
h above it.
Obtain the pressure on the upper surface of the plate mentioned
above from Bernoulli’s equation. Integrate the pressure difference over
the entire surface of the plate, and so show that the force acting on the
plate due to the presence of the source is (rho)*m^2/(4*(pi)*h).Take the pressure
along the lower surface of the plate to be equal to the stagnation pressure
in the fluid.
Solution
z = x + i y z=x+iy
Complex potential general form: F ( z ) = + i F(z)=+i
Complex potential for a source of strength m : F ( z ) = m/ 2 log ( z z 0 ) F(z)=m2log(zz0)
Bernoulli\'s equation for ideal irrotational flow: t + p + 1 2 G = F ( t ) t+p+12G=F(t) where
F ( t ) F(t) is the unsteady Bernoulli constant
y=0 is a streamline in the flow field. Separate real and imaginary parts of the complex potential
so that I can isolate and show that = 0 at y=0. Tease out from the complex potential + i = m 2
log ( z 2 h 2 ) +i=m2log(z2h2), take the exponential of each side to get rid of the log function,
and my i term is tied up in an exponential e + i = e m 2 ( z 2 h 2 ) e+i=em2(z2h2).
Since this flow is ideal, irrotational, and steady that Bernoulii\'s equation would simplify down to
p + 1 2 G = 0.

Why is knowledge of the heritability of a trait important for the study of evolution?
Solution
Hereditary is the passage of genetic information for traits from one generation to another
generation throught assexual or sequal reproduction. Evolution is the change in the inherited
traits of a population of the organisms, when mutations changes the genetic sequences are
inherited across the successive generations. So, the knowledge of heritability of a trait will give
an idea about the genetic history and relationship with the ancestors of the organism is important

Compare and contrast the physical characteristic of protozoans, yeast, and algae.
Solution
Protozoans
Most of the protozoans possess the size range of 10 to 52 micrometers. They can also grow as
large as 1mm and are visible through the microscope. They were previously included in the
Protista family. Protozoans live in the aqueous environments and soil that range widely in the
trophic levels. They move with flagella, cilia or pseudopodia. Protozoans absorb food through
cell membranes. Sporozoans are non-motile forms. Amoeba is the protozoan which does not
have structural components in its cell membrane. Protozoans are eukaryotic and possess
developed organelles. Their cells do not possess cell walls.
Yeast
Some of the dry yeasts that are utilized in the alcoholic fermentation and baking are the
agglomerates of dehydrated cells of Saccharomyces cerevisiae. The powders prepared from the
different yeasts vary in terms of the genetic strain and their specificity in the industrial
application. The physical characteristics of these yeast powders differ. The powders of wine
yeasts and dry baker’s yeast exposed to different levels of relative humidity are identified with
the help of electron microscopy and mechanical analysis. The physical characteristics of the
yeasts that were used to differentiate them include loose bulk density, compressibility, cohesion,
recoverable work in compression, angle of internal friction, and residual asymptotic modulus
after stress relaxation.
Algae
Algae are plants that do not have clear distinction in true roots, stem and leaves. They bear
unicellular or multicellular sex organs that are visible outside. Algae live in aquatic, fresh water
and marine water habitats. Algae that are terrestrial live in the soil, rocks, tree trunks and so on.
Halophytic algae live in saline waters, epizoic algae grow on snails and fish. Endozoic algae live
inside the animals and symbiotic algae live in association with the fungi, bryophytes,
pteridophytes and gymnosperms. There are unicellular or colonial forms of algae or thallus. They
exist as filaments, siphons, and parenchymatous forms. The various pigments present in the algae
include chlorophyll, carotenoids and phycobilins. The reserved food materials of different algae
include cyonophycean starch, starch, floridean starch, laminarin and mannitol. Size of unicellular
alga is about 3micrometers. Multicellular algae vary in their size from 50micrometers to 1mm..

What does the fossil record of Basilosaurid whales tell us about wha.pdf
What does the fossil record of Basilosaurid whales tell us about whale evolution?
Solution
Early whales,like Basilosaurus have tailfins.Such skeletal changes that accommodate an aquatic
lifestyle are especially pronounced in basilosaurids.Their elbow joints were able to lock,allowing
the forelimb to serve as a better control surface and resist the oncoming flow of water as the
animal propelled itself forward.The hindlimbs of these animals were almost nonexistent.They
were so tiny but well-formed hind legs of basilosaurids were probably used as claspers when
mating.The pelvic bones associated with these hind limbs were not connected to the vertebral
column as they were in protocetids.They were fully recognizable whales which lived entirely in
the ocean.This is supported by their fossils usually found in deposits indicative of fully marine
environments.The fossilised stomach contents in one basilosaurid indicates that it ate fish.From
the ear bones to the ankle bones,whales belong with the hippos and other
artiodactyls.Basilosaurid are the intermediates between the Ambulocetus and the modern whales..

The hardenability curves of several iron alloys are shown in the fig.pdf
The hardenability curves of several iron alloys are shown in the figure below. In terms of
alloying additions, 1040<5140<8640<4140<4340. Explain briefly the effect of alloying addition
to the hardenability of the iron alloys.
Solution
The image is not uploaded sir, you can repost including the image. for the effect of alloying
addition to the hardenability of the iron alloys:
Iron is a great buildingmaterial but steel (an alloy made by adding small amounts of nonmetallic
carbon to iron) is stronger, harder, and rustproof. Aluminum is a very light metal but it\'s also
very soft in its pure form. Add small amounts of the metals magnesium, manganese, and copper
and you make a superb aluminum alloy called duralumin, which is strong enough to make
airplanes.
There are two mechanisms that can cause an alloy to form, called atom exchange and the
interstitial mechanism. The relative size of each element in the mix plays a primary role in
determining which mechanism will occur. When the atoms are relatively similar in size, the atom
exchange method usually happens, where some of the atoms composing the metallic crystals are
substituted with atoms of the other constituent. This is called a substitutional alloy. With the
interstitial mechanism, one atom is usually much smaller than the other, so cannot successfully
replace an atom in the crystals of the base metal. The smaller atoms become trapped in the
spaces between the atoms in the crystal matrix, called the interstices. This is referred to as an
interstitial alloy. Steel is an example of an interstitial alloy, because the very small carbon atoms
fit into interstices of the iron matrix that\'s what makes it more hard
Sulfur, when present, forms iron sulfide, which prevents the formation of graphite and increases
hardness. The problem with sulfur is that it makes molten cast iron viscous, which causes short
run defects.
To counter the effects of sulfur, manganese is added because the two form intomanganese
sulfide instead of iron sulfide. The manganese sulfide is lighter than the melt so it tends to float
out of the melt and into the slag. The amount of manganese required to neutralize sulfur is 1.7 ×
sulfur content + 0.3%. If more than this amount of manganese is added, then manganese carbide
forms, which increases hardness andchilling, except in grey iron, where up to 1% of manganese
increases strength and density
Titanium is added as a degasser and deoxidizer, but it also increases fluidity.
0.15–0.5% vanadium is added to cast iron to stabilize cementite, increase hardness, and increase
resistance to wear and heat.
0.1–0.3% zirconium helps to form graphite, deoxidize, and increase fluidity.[3]
In malleable iron melts, bismuth is added, on the scale of 0.002–0.01%, to increase how much
silicon can be added.
In white iron, boron is added to aid in the production of malleable iron; it also reduces the
coarsening effect of bismuth.

A man with Klinefelter syndrome (XXY) is found to be colour-blind (a.pdf
A man with Klinefelter syndrome (XXY) is found to be colour-blind (an X-linked recessive
phenotype). Both his parents had normal vision.
a) Explain the stimultaneous origin of Klinefelter syndrome and color blindness by the abnormal
behaviour of chromosome at meiosis.
b) Can your explanation distinguish whether the abnormal chromosomal behaviour occured at
the first or second division of meiosis?
Solution
The question it self is a blender. Because, if the parents have normal vision, In of XXY, the Y
chromosome came from father. The two X chromosomes might came from mother. Here the
Mother had normal vision means she might act as a carrier (Xx). The the same is present in the a
man with Klinefelter syndrome the genotype would me XxY. Due to presence of Normal X
chromosome surely he should have a normal vision.
There is an another chance, that the X chromosome might came form father along with Y
chromosome, at this chance the father should have color blindness. But here the father had
normal vision. So Check your question once and get me back..
5) What is the dependent variable measured in the BOD test (Explain .pdf
5) What is the dependent variable measured in the BOD test? (Explain how you reach your
conclusion) 6) The BOD test is an indirect measure of the concentration of organic
biodegradable materials in a wastewater. Explain in which way is considered an \"indirect\"
Solution
1. BOD is not a specific pollutant. BOD is a measure of the amount of oxygen required by
bacteria and other microorganisms to oxidize any organic matter in the water biochemically.
BOD analysis dose not oxidize all of the organic matter present in the waste. Only the organics
that are biochemically degradable during the standard 5 day time are oxidized. A very low mount
of BOD would indicate either clean water, or that the available microorganisms are uninterested
in consuming the available organic compounds, or that the microorganisms are dead or dying.
Temperature has a pronounced effect on oxygen uptake, because metabolic activity increases
significantly at higher temperature. The time allotted for the test is also important, since the
amount of oxygen used increases with time. Light is also an important variable since most
natural waters contain algae and oxygen that can be replenished in the bottle if light is available.
And the all that is depending on the temperature and and the amount of organic content is
Oxygen so it is the dependent variable .
2.The BOD test is considered as indirect measure of organic biodegradable matter because in this
test we are not going to test and examine the type and concentration of each organic matter by
directly , by measuring the oxygen demand we can easily find the concentration of biodegradable
organic matter.

RAREST MethodWrite a method rarest that accepts a map whose keys a.pdf
RAREST Method
Write a method rarest that accepts a map whose keys are strings and whose values are integers as
a parameter and returns the integer value that occurs the fewest times in the map. If there is a tie,
return the smaller integer value. If the map is empty, throw an exception.
For example, suppose the map contains mappings from students\' names (strings) to their ages
(integers). Your method would return the least frequently occurring age. Consider a map variable
m containing the following key/value pairs:
Three people are age 20 (Jeff, Kasey, and Kim), two people are age 22 (Alyssa and Stef), and
four people are age 25 (Char, Dan, Mogran, and Ryan). So a call of rarest(m) returns 22 because
only two people are that age.
If there is a tie (two or more rarest ages that occur the same number of times), return the
youngest age among them. For example, if we added another pair of Kelly=22 to the map above,
there would now be a tie of three people of age 20 (Jeff, Kasey, Kim) and three people of age 22
(Alyssa, Kelly, Stef). So a call of rarest(m) would now return 20 because 20 is the smaller of the
rarest values.
Solution
Rarest Method:
Algorithm:
Input: Key value pairs as a dictionary
Expected output: Least frequent value from key value pairs
We see that \'22\' has occurred twice, and \'25\' four times. Now we have to find it using out
algorithm:
Now, we have the following values in \'min_age\' and \'frequency\' variables:
min_age = 22
frequency = 2
If we add kelly to the initial key value pair, we will get the min_age as 20 and frequency as 3 as
expected.
The following python code can be referred to understand the algorithm:
def rarest(d):
age_count = {}
for key,value in d.items():
if value in age_count:
age_count[value]+=1
else:
age_count[value]=1
min_age=0
freq=0
for key,value in age_count.items():
if freq==0:
freq=value
min_age=key
elif freq>value:
freq=value
min_age=key
elif freq==value:
if min_age>key:
min_age=key
return min_age,freq,frd

1. Martin would say that in a society with ample protection for whis.pdf
1. Martin would say that in a society with ample protection for whistle blowers that _________.
a. Engineers have the same prima facie obligation to blow the whistle as they would in a society
where whistleblowers are not as strongly protected (because the obligation is independent of
factors such as legal protection for whistleblowers).
b. Engineers have a much weaker prima facie obligation to blow the whistle than they would in a
society where whistleblowers are not as strongly protected.
c. Engineers have no obligation to blow the whistle because the prima facie obligation is
contextually dependent (and factors such as legal protections are contextually relevant).
d. Engineers have a stronger prima facie obligation to blow the whistle than they would in a
society where whistleblowers are not as strongly protected.
2. Martin argues that the fact that whistleblowing may involve great personal sacrifice on the part
of an engineer means that engineers do not have a responsibility to blow the whistle (instead the
responsibility rests with managers because it is part of their professional role to manage moral
conflicts.)
a. true
b. false
3. Martin Argues that Whistle blowing is a prima facie responsibility for engineers because they
are people with moral rights.
a. true
b. false
4. Helen is a engineer at a large chemical plant. She has some reason to believe that the plant
manager is knowingly violating local environmental laws by encouraging unsafe dumping
practices. Some relevant facts about Helen\'s situation are as follows:
I) She does have reasonable documentation of the plant managers behavior
II) She has not yet gone through any of the normal organizational channels in order to resolve
the conflict
III) She has a reason to think that the unsafe dumping practice pose a serious threat to public
health and safety
According to Martin\'s view, does Helen have a prima facie responsibility to blow the whistle?
a. Yes, she does have an prima facie obligation to blow the whistle, but not a strong one (because
she cannot be 100% sure that the dumping practices constitute a serious moral issue.)
b. No, she does not have a prima facie obligation to blow the whistle because whistle blowing is
always supererogatory.
c. Yes, in light of the fact that the dumping practices pose a serious (and credible) threat, she
does have a prima facie obligation to blow the whistle.
d. No, she does not have a prima facie obligation to blow the whistle because her situation as
described does not meet the minimal standards for the obligation to hold.
5. Which of the following situations exemplifies what Martin meant by saying that an engineer\'s
obligation to blow the whistle is sensitive to context?
a. That morality itself is subjective because there is no objective answer to the question of when
we ought to blow the whistle.
b. That moral decisions regarding whistle blowing are completely determined by what
professional organizations say about it.
c. That what counts .

Operation Blue Star - Saka Neela Tara
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.
How to Break the cycle of negative Thoughts
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”.

What does the fossil record of Basilosaurid whales tell us about wha.pdf
What does the fossil record of Basilosaurid whales tell us about whale evolution?
Solution
Early whales,like Basilosaurus have tailfins.Such skeletal changes that accommodate an aquatic
lifestyle are especially pronounced in basilosaurids.Their elbow joints were able to lock,allowing
the forelimb to serve as a better control surface and resist the oncoming flow of water as the
animal propelled itself forward.The hindlimbs of these animals were almost nonexistent.They
were so tiny but well-formed hind legs of basilosaurids were probably used as claspers when
mating.The pelvic bones associated with these hind limbs were not connected to the vertebral
column as they were in protocetids.They were fully recognizable whales which lived entirely in
the ocean.This is supported by their fossils usually found in deposits indicative of fully marine
environments.The fossilised stomach contents in one basilosaurid indicates that it ate fish.From
the ear bones to the ankle bones,whales belong with the hippos and other
artiodactyls.Basilosaurid are the intermediates between the Ambulocetus and the modern whales..

The hardenability curves of several iron alloys are shown in the fig.pdf
The hardenability curves of several iron alloys are shown in the figure below. In terms of
alloying additions, 1040<5140<8640<4140<4340. Explain briefly the effect of alloying addition
to the hardenability of the iron alloys.
Solution
The image is not uploaded sir, you can repost including the image. for the effect of alloying
addition to the hardenability of the iron alloys:
Iron is a great buildingmaterial but steel (an alloy made by adding small amounts of nonmetallic
carbon to iron) is stronger, harder, and rustproof. Aluminum is a very light metal but it\'s also
very soft in its pure form. Add small amounts of the metals magnesium, manganese, and copper
and you make a superb aluminum alloy called duralumin, which is strong enough to make
airplanes.
There are two mechanisms that can cause an alloy to form, called atom exchange and the
interstitial mechanism. The relative size of each element in the mix plays a primary role in
determining which mechanism will occur. When the atoms are relatively similar in size, the atom
exchange method usually happens, where some of the atoms composing the metallic crystals are
substituted with atoms of the other constituent. This is called a substitutional alloy. With the
interstitial mechanism, one atom is usually much smaller than the other, so cannot successfully
replace an atom in the crystals of the base metal. The smaller atoms become trapped in the
spaces between the atoms in the crystal matrix, called the interstices. This is referred to as an
interstitial alloy. Steel is an example of an interstitial alloy, because the very small carbon atoms
fit into interstices of the iron matrix that\'s what makes it more hard
Sulfur, when present, forms iron sulfide, which prevents the formation of graphite and increases
hardness. The problem with sulfur is that it makes molten cast iron viscous, which causes short
run defects.
To counter the effects of sulfur, manganese is added because the two form intomanganese
sulfide instead of iron sulfide. The manganese sulfide is lighter than the melt so it tends to float
out of the melt and into the slag. The amount of manganese required to neutralize sulfur is 1.7 ×
sulfur content + 0.3%. If more than this amount of manganese is added, then manganese carbide
forms, which increases hardness andchilling, except in grey iron, where up to 1% of manganese
increases strength and density
Titanium is added as a degasser and deoxidizer, but it also increases fluidity.
0.15–0.5% vanadium is added to cast iron to stabilize cementite, increase hardness, and increase
resistance to wear and heat.
0.1–0.3% zirconium helps to form graphite, deoxidize, and increase fluidity.[3]
In malleable iron melts, bismuth is added, on the scale of 0.002–0.01%, to increase how much
silicon can be added.
In white iron, boron is added to aid in the production of malleable iron; it also reduces the
coarsening effect of bismuth.

RAREST Method
Write a method rarest that accepts a map whose keys are strings and whose values are integers as
a parameter and returns the integer value that occurs the fewest times in the map. If there is a tie,
return the smaller integer value. If the map is empty, throw an exception.
For example, suppose the map contains mappings from students\' names (strings) to their ages
(integers). Your method would return the least frequently occurring age. Consider a map variable
m containing the following key/value pairs:
Three people are age 20 (Jeff, Kasey, and Kim), two people are age 22 (Alyssa and Stef), and
four people are age 25 (Char, Dan, Mogran, and Ryan). So a call of rarest(m) returns 22 because
only two people are that age.
If there is a tie (two or more rarest ages that occur the same number of times), return the
youngest age among them. For example, if we added another pair of Kelly=22 to the map above,
there would now be a tie of three people of age 20 (Jeff, Kasey, Kim) and three people of age 22
(Alyssa, Kelly, Stef). So a call of rarest(m) would now return 20 because 20 is the smaller of the
rarest values.
Solution
Rarest Method:
Algorithm:
Input: Key value pairs as a dictionary
Expected output: Least frequent value from key value pairs
We see that \'22\' has occurred twice, and \'25\' four times. Now we have to find it using out
algorithm:
Now, we have the following values in \'min_age\' and \'frequency\' variables:
min_age = 22
frequency = 2
If we add kelly to the initial key value pair, we will get the min_age as 20 and frequency as 3 as
expected.
The following python code can be referred to understand the algorithm:
def rarest(d):

Mitochondria were most likely acquire earlier than plastids in the e.pdf
Mitochondria were most likely acquire earlier than plastids in the evolution of eukaryotes. Give
one piece of evidence in support of that statement?
Solution
Mitochondrial origin is monophyletic (from common ancestor). Their free living ancestors
Cyanobacteria was in existence before proteobacteria and Cyanobacteria is much older in
evolution.
Mitochondria present in all organisms who has Chloroplast but reverse is not true.
Case of endosymbiosis of a chloroplast like organelle (spheroid bodies) in the named diatom
Rhopallodia gibba which already has a secondary plastid shows secondry endosymbiosis but this
kind of any case is not reported for mitochondria..
1. Martin would say that in a society with ample protection for whis.pdf
1. Martin would say that in a society with ample protection for whistle blowers that _________.
a. Engineers have the same prima facie obligation to blow the whistle as they would in a society
where whistleblowers are not as strongly protected (because the obligation is independent of
factors such as legal protection for whistleblowers).
b. Engineers have a much weaker prima facie obligation to blow the whistle than they would in a
society where whistleblowers are not as strongly protected.
c. Engineers have no obligation to blow the whistle because the prima facie obligation is
contextually dependent (and factors such as legal protections are contextually relevant).
d. Engineers have a stronger prima facie obligation to blow the whistle than they would in a
society where whistleblowers are not as strongly protected.
2. Martin argues that the fact that whistleblowing may involve great personal sacrifice on the part
of an engineer means that engineers do not have a responsibility to blow the whistle (instead the
responsibility rests with managers because it is part of their professional role to manage moral
conflicts.)
a. true
b. false
3. Martin Argues that Whistle blowing is a prima facie responsibility for engineers because they
are people with moral rights.
a. true
b. false
4. Helen is a engineer at a large chemical plant. She has some reason to believe that the plant
manager is knowingly violating local environmental laws by encouraging unsafe dumping
practices. Some relevant facts about Helen\'s situation are as follows:
I) She does have reasonable documentation of the plant managers behavior
II) She has not yet gone through any of the normal organizational channels in order to resolve
the conflict
III) She has a reason to think that the unsafe dumping practice pose a serious threat to public
health and safety
According to Martin\'s view, does Helen have a prima facie responsibility to blow the whistle?
a. Yes, she does have an prima facie obligation to blow the whistle, but not a strong one (because
she cannot be 100% sure that the dumping practices constitute a serious moral issue.)
b. No, she does not have a prima facie obligation to blow the whistle because whistle blowing is
always supererogatory.
c. Yes, in light of the fact that the dumping practices pose a serious (and credible) threat, she
does have a prima facie obligation to blow the whistle.
d. No, she does not have a prima facie obligation to blow the whistle because her situation as
described does not meet the minimal standards for the obligation to hold.
5. Which of the following situations exemplifies what Martin meant by saying that an engineer\'s
obligation to blow the whistle is sensitive to context?
a. That morality itself is subjective because there is no objective answer to the question of when
we ought to blow the whistle.
b. That moral decisions regarding whistle blowing are completely determined by what
professional organizations say about it.
c. That what counts .

Operation Blue Star - Saka Neela Tara
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.
How to Break the cycle of negative Thoughts

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.pdf
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.
