Jawaharlal Nehru's significant book 'Glimpses of World History' has motivated me to create this comprehensive record of world events, spanning from ancient times to the present day, based on insights collected from the works of various authors. -The Blogger
Difference between Earth and World in the English language: The terms "earth" and "world" have distinct meanings in the English language. "Earth" refers to the physical planet we inhabit, while "world" can denote a broader range of concepts, including other planets, human society, and even the universe. The distinction is important as it affects how the terms are used in various contexts, from geography to philosophy and literature. In this document, we have used the word ‘WORLD’ in a broader range of concepts.

π c. 6,000,000,000: The estimated age of the Solar
System (variously
estimated as 4,700,000,000 to
6,500,000,000)[3]
Details of the Planets' names in our Solar System:
1. Mercury
1.
Planet Mercury is the closest planet to the Sun in our Solar
system. Its size is also the smallest among all other planets.
- We can see this planet from Earth with binoculars in the morning and evening, as the intensity of the sun is low at these times.
- Life is impossible on Mercury because of the absence of air.
- This planet’s maximum and minimum temperatures are 430°C (midday) and -180°C (midnight), respectively.
- The
distance from Mercury to the Sun is 57.91 million Km, and it takes only 88
days to complete one revolution around the Sun.
- There
are no satellites on Planet Mercury.
- Elements
like Sulphur and Chlorine are found in large quantities on this planet.
- The
abundance of iron is found on this planet because of its rocky surface,
and due to this, its color is also dark brown.
2. Venus
- Planet Venus is the second
closest planet to the Sun and the closest planet to Earth among all the
planets in the Solar System.
- It is also called the Sister of
Planet Earth because of its similarities like atmospheric presence,
features, weight, size, etc.
- This planet is called the
morning and evening stars due to its brightness of this planet. It is also
the second brightest object in the night after the Moon.
- Venus is considered to be the
hottest planet in the Solar System. People consider Mercury to be the
hottest planet because it is near the Sun, but this is not true. The night
and day temperatures on this planet are almost the same, which is 475 °C.
- One day on Planet Venus is
about 243 Earth days and takes only 225 days to make one complete orbit
around the Sun.
- This planet also does not have
any satellites.
- It rotates in the opposite
direction from the direction of rotation of other planets – from east to
west, and the distance from the Sun is estimated to be 108.2 million Km.
3. Earth
- Earth is the only planet in the solar system where life
exists.
- Earth comes in third place
among the planets through the distance from the Sun, which is also called
the blue planet, as the surface is mostly filled with water.
- It is the fifth-largest planet in our Solar System, and this planet has a
satellite named Moon, which was the brightest object at night in our solar
system. The shape of the earth is like a Geoid (a hypothetical solid figure whose surface corresponds to
mean sea level and its imagined extension under (or over) land areas.).
- Like other planets, Earth also
revolves around the Sun in its own orbit, which takes 365 days (1 year) to
make one revolution of the Sun and 24 hours to make one rotation on its
own axis.
- Earth’s polar axis diameter is
12713.6 Km, and its equatorial diameter is 127
- The distance between Earth and the Sun is around 148.76
million Km,
whereas the Moon is nearly 3,84,400
km away from this planet.
- It takes only 8 minutes and 18
seconds for the sun ray to reach the earth.
- Earth’s surface is 71%
hydrosphere (water) and 29% lithosphere (land), where humans, animals,
birds, and other land creatures live and the water creatures live in
water.
- The rotation of the earth
causes day and night and the revolution around the sun causes the change
of seasons because the pole in which the Earth revolves around the Sun is
elliptical in size due to which the distance between the Sun and the Earth
keeps on changing, and the minimum distance is called Perihelion, and the
maximum distance is called Aphelion.
- This planet is covered with a protective Ozone layer
that protects the Earth’s atmosphere from the UV rays of the Sun.
Earth
had no oxygen in the beginning. Then a volcano erupted: Story by
Read in detail: When Earth evolved, it did not have the life-supporting oxygen that we breathe today. Researchers have now identified the conditions on the planet before the evolution of oxygen by using rock fossils.
"Fossils are like time capsules, preserving life's story in stone," said Richard Fortey, a British palaeontologist, geologist, and writer.
Researchers analysed stromatolites, layered rock-like formations made by Cyanobacteria (one of the oldest bacteria). They hold ancient records from two-and-a-half billion years ago.
HOW NITROGEN HELPED EARTH
The team analyzed nitrogen cycling patterns within ancient stromatolites, preserved in southern Zimbabwe.
Nitrogen, which is vital for life on Earth, must be converted into usable, bio-available, forms as it passes through the atmosphere, soil, plants, and animals in the nitrogen cycle.
Nitrogen cycling patterns were chosen as they can help in finding the Earth's condition before the evolution of oxygen and the beginning of photosynthesis. This method of research is also less explored when compared to oxygen evolution and its impact.
Dr. Ashley Martin from the Department of Geography and Environmental Sciences at Northumbria University said that nitrogen and phosphorus are the two key nutrients that control productivity in the oceans over periods.
Dr. Martin added a note on the importance of ammonium for the biological process, and mentioned the presence of a high amount of nitrogen deep inside the ocean in the form of ammonium.
This ammonium reservoir would have been very beneficial for early life, providing the nitrogen source needed for biological processes to occur.
As early oceans had very little oxygen, they were influenced by volcanic activities. This in turn helped in the growth of microbes which acted as pioneers in the evolution of oxygen.
"We have long been puzzled by the unusual nitrogen isotope values in these rocks. "Our new findings suggest a strong linkage to hydrothermal nutrient recycling, meaning that early life may in part have been fuelled by volcanic activity," Dr Eva Stueken from the University of St Andrews explained.
The study published in Nature Communications highlights the role of the volcano, which had a lasting impact on the evolution of life at that time.
4. Mars
- Mars
is the fourth planet in the solar system according to the distance of the
planets from the Sun.
- Mars is the second smallest planet
in the Solar System after Planet Mercury.
- Mars is also called the Red Planet
because its surface looks like rusted iron, and this planet’s atmosphere
is very viral. This planet’s surface is dry and dusty like a desert, due
to which dust storms run on this planet, sometimes it is so huge that it
lasts for months.
- The average distance of this planet
from the Sun is 227.9 million km.
- One
day on Mars is approx. 24 hours as on Earth, and one year is about 687 Earth days.
- It
has two natural satellites, named Phobos and Deimos. The Deimos satellite
is the smallest satellite in the solar system.
- There is a mountain on Mars
named Nix Olympia, whose height is three times more than Earth’s Mount
Everest (Mt. Everest), and also a giant volcano on this planet named
Olympus Mons.
5. Jupiter
- Jupiter is the largest planet
among other planets in the Solar System, and in terms of distance from the
Sun, it comes fifth, whose distance is about 746.22 million km from the
Sun.
- It
takes only 10 hours to complete one rotation and an estimated 11.9 Earth
years (one Jovian year) to make one revolution around the Sun.
- The
diameter of the planet Jupiter is 1,39,820 Km, which is 11 times more than
Earth’s diameter.
- This
planet has 79 named satellites, of which Ganymede is the largest satellite
in the Solar System.
- Like
stars, this planet also receives energy from the sun’s rays and emits
twice as much as energy. This planet has its own radio energy. Therefore
this planet also attains the qualities of stars.
- Hydrogen and helium gas are
present in the atmosphere of this planet. The atmospheric pressure of this
planet is 10 million times greater than that of the Sun.
6. Saturn
- Saturn is the sixth planet in
our Solar system according to the distance of the sun and is the
second-largest planet in the solar system in size, whose distance from the
Sun is around 1.4805 billion Km.
- The
diameter of Saturn is 1,16,480 Kms and is the visible planet in our Solar
system.
- It
takes only 10.7 hours to complete one rotation and an estimated 29.5 Earth
years to make one revolution around the Sun.
- Saturn
has about 82 satellites, out of which 53 are known satellites, and the
search for the other 29 is still going on.
- Satellite
Titan is the largest satellite of Saturn and the second-largest satellite
in the Solar System. Nitrogen is present in the atmosphere of this
satellite.
- This
planet is also called a gas ball or galaxy in the Solar system because, in
the middle of this planet, there are seven developed spectacular rings
like a circle, which revolve around this planet due to gravity.
- The surface of this planet is
not solid like Earth or other planets but is of gasses like Hydrogen and
Helium.
7.
Uranus
- Uranus comes in seventh place
in the distance from the Sun in the Solar system, which is at a distance
of 2.9491 billion Km from the Sun.
- Like
the rings of the planet Saturn, Uranus also has five rings, whose names
are- Alpha, Beta, Gamma, Delta, and Epsilon.
- The
diameter of the planet Uranus is 50,724 km which is the third-largest
planet in diameter.
- This
planet takes about 17 hours to rotate in its axis (one Uranian day) and 84
Earth years (one Uranian year) to complete an orbit of the Sun.
- Planet
Uranus has 27 known satellites, and all satellites of this planet revolve
in the opposite direction of the earth.
- This planet appears blue in
appearance because Methane gas is present in large quantities on this
planet as the atmosphere of this planet consists of gasses like Hydrogen,
Helium, Methane, and Ammonia.
8.
Neptune
- The Neptune planet comes eight
in the distance from the Sun in the Solar System, which is 4.4747 billion
Kms.
- It
takes around 16 hours (one Neptunian day) to complete one rotation and 165
Earth years (one Neptunian year) to complete one orbit around the sun.
- It
looks like giant ice, and the atmosphere is gaseous as it contains 80%
Hydrogen, 19% Helium, and 1% amount of water and methane.
- It has 14 satellites, of which
Triton and Proteus are the main ones.

§ Pluto is a
dwarf planet[4]
located in the Kuiper Belt, a region of icy bodies beyond Neptune's orbit.
Discovered in 1930, Pluto was initially classified as the ninth planet in our
solar system but was redefined as a dwarf planet by the International
Astronomical Union in 2006. It is characterized by its small size, irregular
orbit, and diverse geological features, including mountains, valleys, and
glaciers.

Q. When did man first find out about dinosaurs?
A. No human being
has ever met a dinosaur alive. Dinosaurs were animals that inhabited most parts
of the world, but they died everywhere about 6,500,000 years ago. Dinosaurs
were extinct when humans came into the world.
Dinosaurs are known to
us because of their remains. These are bones, found in skeletons or separately;
footprints in the rock; skin-prints, also in the rock; and eggs.
There is some doubt as to when the first recognizable dinosaur bones were discovered. Footprints have been known for many years. A dinosaur skeleton may have been seen at Haddonfield, New Jersey, toward the end of the 1770s.
The first bones that are still available for examination and identification are some that were discovered in England. One set was found in 1822 and is now in the British Museum of Natural History in London.
Another set of dinosaur bones found about the same time was the basis for the first scientific description of any dinosaur. This was done in 1824 by a professor at Oxford University.
So it appears that human knowledge of dinosaurs is quite recent.
Dinosaur specimens have been found in great numbers in the United States, Canada, Argentina, Brazil, India, Africa, Australia, Mongolia, China, France, Germany, Portugal and the Soviet Union (which no longer exists in the 20th century). This indicates that dinosaurs really lived all over the world. - 16/11/2022

π c. 38,000,000: Oligocene
Age: extension of land masses; monkeys and apes existed.
Q. What is the difference between monkeys and apes?
By Alison Eldridge
Monkeys and apes are both primates, which mean they’re both parts of the human family tree. As distinguished relatives, we should probably be able to tell them apart. But when you look at a gibbon or a marmoset, how do you know which is a monkey and which is an ape?
The quickest way to tell the difference between a monkey and an ape is by the presence or absence of a tail. Almost all monkeys have tails; apes do not. Their bodies are different in other ways too: monkeys are generally smaller and narrow-chested, while apes are larger and have broad chests and shoulder joints that allow them to swing through trees (while some monkeys also have this ability, most of them are built for running across branches rather than swinging). Although you can’t recognize this difference on sight, apes have an appendix and monkeys do not. Apes are generally more intelligent than monkeys, and most species of apes exhibit some use of tools. While both monkeys and apes can use sounds and gestures to communicate, apes have demonstrated higher ability with language, and some individual apes have been trained to learn human sign languages.
However, perhaps the best way to remember, like with so many things, is rote memorization. There are only a handful of ape species, while there are hundreds of species of monkeys. If the primate you’re trying to place is not a human, gibbon, chimpanzee, bonobo, orangutan, or gorilla (or a lemur, loris, or tarsier), then it’s a monkey.

[1]Pre-history means literally “before
history”, from the Latin word for “before,” prΓ¦,
and Greek ΞΉΟΟΞΏΟΞ―Ξ±.
[2] The Neolithic Revolution, also known as the Agricultural Revolution,
refers to the significant transition in human history from nomadic
hunter-gatherer societies to settled agricultural communities. This period
marked the development of farming, the domestication of animals, and the
establishment of permanent settlements, which allowed for larger populations
and the rise of early civilizations. It is considered a pivotal moment in human
history, occurring around 12,000 years ago.
[3] The
Solar System: The collection of eight planets and their moons in orbit
round the sun, together with smaller bodies in the form of asteroids,
meteoroids, and comets. The major
planets of the solar system are (in order of distance from the sun) Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto, which is very much known as ninth planet, is a
dwarf planet.
[5] algae (plural noun of alga), a simple, non-flowering, and typically aquatic plant-like organism of a large group that includes the seaweeds and many single-celled forms. Algae contain chlorophyll but lack true stems, roots, leaves, and vascular tissue. Origin: mid 16th century: from Latin, ‘seaweed’.
[6] Trilobites
are extinct fossil arthropods that first appeared around 521 million years ago
during the Cambrian Period. They are easily recognized by their distinctive
three-lobed, three-segmented form. Trilobites were exclusively marine animals
and are known from more than 10,000 fossil species. They were arthropods,
divided into three parts from head to tail and from side to side. Trilobites
were abundant during the Cambrian and Ordovician periods but eventually went
extinct. -Britannica
[7] Sponges
are primitive multicellular aquatic animals that constitute the phylum
Porifera. They are permanently affixed (sessile), mostly marine, solitary or
colonial invertebrates. Sponges have bodies full of pores and channels allowing
water to circulate through them. They consist of jelly-like mesohyl sandwiched
between two thin layers of cells. The mesohyl contains embedded amoeboid cells
that secrete tiny needles called spicules or protein fibers that help give the
sponge its structural strength. -Britannica
[8] Osteichthyes
refers to a class of vertebrates known as bony fish, characterized by an
endoskeleton primarily composed of bone tissue. This class includes over 30,000
species, making it the largest class of vertebrates. Key features of
Osteichthyes include a skeletal endoskeleton, gill covers (operculum), and, in
most cases, paired fins.
[9] The Jurassic Age, spanning
from approximately 201.3 million to 145
million years ago, was a significant period in Earth's history marked by
the dominance of dinosaurs and major geological changes. The Jurassic Period is
part of the Mesozoic Era and is divided into three epochs: Early Jurassic
(201.3 to 174.1 million years ago), Middle Jurassic (174.1 to 163.5 million
years ago), and Late Jurassic (163.5 to 145 million years ago). -Britannica
