Q1 What are some facts you know?
KR Facts everyone knows but raison detat is not as it is GK
(not Gopalkrishnan)
Q 1.Human brain is most complex thing known.
KR All who are sane knew it. But what is meant by complex?
The human brain has been described as the most complex known structure in
the universe (Dolan, 2007). The numbers are indeed staggering: Ingenious
research methods that examined the almost 1,000 brain regions, and
extrapolated the expected density from small samples, estimated the total
number of nerve cells—or neurons—in the brain at 86 billion (Azevedo et
al., 2009).On top of this, there are another 85 billion cells that serve
various functions in the brain. Even more incredible is that each one of
these neurons on average connects to thousands of other neurons, resulting
in an estimated 100 trillion connections (Caruso, 2023; Zimmer, 2011).
These connections allow signals to travel between neurons and can function
as logic gates, giving it a computing power of one exaflop—that is one
quintillion mathematical operations per second (Madhavan, 2023)—that is a
billion times a billion or 1 followed by 18 zeros.And it does all of this
in an incredibly efficient way, using only 20 watts of power. In
comparison, one of the most advanced supercomputers in the world requires a
million times more power (20 megawatts) to reach anything near a similar
computing capacity (Madhavan, 2023).
The total length of this complex fiber network is estimated to be around
500,000km or over 310,000 miles long (Science Daily, 2017). Signals inside
this network can reach traveling speeds of 431 kmh or 268 mph (Ross, 2011).
Such complexity comes at a biological cost: Despite only accounting for
around 2 percent of the body’s mass, the brain consumes around 20 percent
of the body’s total energy (Herculano-Houzel, 2012). A widespread myth is
that there are more neurons in the brain than there are stars in the Milky
Way. This is not actually true: There are around 200 to 400 billion stars
in our galaxy and the commonly cited 100 billion neurons in the brain is
probably an overestimation (Stoke & Boytek, 2013). A more accurate figure
is around 86 billion (Azevedo et al., 2009).
So, is it really the most complex structure we know of? Many experts still
seem to believe so, from physicist Michio Kaku (2014) who described the
three pounds in our head as the most complex object in the solar system
(pp.2-3), to neuroscientist Christof Koch (2013), psychiatrist Sir Robing
Murray (2012), and neurobiologist Gerald Fischbach (1992), who all
described it as the most complex structure in the known universe. This is
because the complexity is much greater than the number of cells themselves:
The many complex connections and the myriad interactions give the brain not
only structural complexity but turns it into an intricately functioning
whole. While stars and galaxies interact, they cannot rival the complicated
interplay, signalling, and computation going on between neurons. It is
difficult for us to grasp very large numbers, like the number of neurons or
connections in the brain. Another way to highlight the complexity of the
brain is through something we are more familiar with money, time, and
people.
The Human Brain Project was one of the biggest research endeavours the
European Union has ever undertaken: It had a budget of €600 million, ran
for 10 years, and involved 500 scientists across different institutions
(Naddaf, 2023). The goal was to map and then simulate the entire human
brain. Although the project managed to create 3D maps of around 200 brain
structures, this represents only a fraction of the initial goal (Naddaf,
2023). Similarly, the US BRAIN project, announced by President Obama in
2013 with an initial funding of $100 million is still ongoing but had to
scale back its initial goal of mapping the entire human brain at the level
of individual neurons (Mullin, 2023). Critics have pointed out problems in
the management of these projects (Mullin, 2023; Naddaf, 2023) but a key
reason for the seeming failure is the underlying complexity of the brain
itself. Hundreds of millions of dollars and over a decade of research by
leading scientists have not been able to fully describe the structure of
the brain. And understanding the structure of the brain is much simpler
than grasping its functioning. A leading neuroscientist wagered in 1998
that the neural mechanisms of consciousness would be discovered within 25
years. He recently conceded his bet lost (Lenharo, 2023).
Despite the tremendous progress that has been made in understanding the
brain, its staggering complexity means that we are still a long way off
from fully understanding its structure and even further away from fully
understanding the way it functions. Many ancient cultures saw the heart as
the seat of thought, emotion, and volition and had little regard for the
brain. In ancient Egypt, for example, the brain was discarded during the
mummification process, while the heart was carefully preserved (see Ancient
Concepts of the Mind, Brain (and Soul), Pang, 2023a). We now know that the
brain is linked to our thoughts, emotions, and experiences. Evidence for
this includes that damage to the brain impacts those processes (Vaidya et
al., 2019), that these processes are congruent with measured electrical
activity in the brain, as well as with images taken (for example through
functional magnetic resonance images or fMRI; DeSouza et al., 2012), and
that psychoactive drugs that target the brain can influence these functions
(Buxton et al., 2008).
There is further evidence from developmental psychology and from brain
stimulation experiments. Despite the tremendous progress that has been made
in neuroscience, psychology, and neurology, many aspects of the brain
remain mysterious. The Australian philosopher David Chalmers (1995)
suggested that while neuroscience will likely be able to answer most
conventional (or what he termed "easy") questions about the brain, the hard
problem of why electrical impulses in the brain lead to conscious
experience may not be solved {PSYCHOLOGY TODAY}

Q 4. Yawning with stretching is known as pandiculating.
KR Pandiculation is our innate response to the sensations of lack of
movement and to tension building up in our muscles—which often go hand in
hand.
Pandiculation sends biofeedback to our nervous system regarding the level
of contraction in our muscles, thereby helping to prevent the buildup of
chronic muscular tension. This is an extremely important function of the
pandicular response. A pandiculation contracts and releases muscles in such
a way that the gamma loop, a feedback loop in our nervous system that
regulates the level of tension in our muscles, is naturally reset. This
resetting reduces muscular tension and restores conscious, voluntary
control over our muscles.
Preventing the buildup of tension in our muscles is critical to maintaining
healthy posture and movement throughout our lives. Foetuses have been
observed pandiculating in the womb, showing how deeply ingrained the
pandicular response is in our nervous system and how fundamental it is to
our musculoskeletal functioning.
Unfortunately, as we age and develop habitual ways of standing and moving,
our natural pandicular response typically can’t counteract all the learning
that occurs in our nervous system. Our repetitive, sedentary lifestyles are
quite different than the active lifestyles of our ancestors. We tend to
build up muscle tension at a much faster rate than they did because we move
less and tend to have less variety in our movements. As we gradually build
up muscle tension and lose awareness and control of our muscles, our
pandicular response often becomes inhibited.
Xxxxxxxxxxxxxxxxxxxx
KR Like this we have 14 types of natural movements which will blow up
your minds!!
1 *Myoclonus* is muscle jerking, in which the muscles suddenly tighten
and release. Everyone including children, has experienced this with hiccups
or "sleep start," the sudden jerk that may happen just as a person falls
asleep. These types of myoclonuses are normal, but the condition can become
severe and greatly disrupt normal life.
Action myoclonus: This is triggered by trying to move.
Stimulus-sensitive myoclonus: This is triggered by noise, light, or being
startled.
Essential myoclonus: This occurs for no known reason and usually stabilizes
over time.
Epileptic myoclonus: This is a form of epilepsy.
Secondary myoclonus: This is due to neurodegenerative disease.
2 dystonia or muscle spasms
Dystonia is involuntary muscle spasm, where the muscles contract and don't
want to release. This produces meaningless, uncoordinated movements.
Voluntary motion: It may be initiated by voluntary motion, especially
specific activities such as writing or playing a musical instrument.
It worsens with stress or fatigue
Areas affected: It may affect the eyelids, jaw, tongue, lips, lower face
and neck, vocal cords, and upper or lower extremities.
Neck muscle contraction: This is sometimes painful and causes the head to
be held at odd angles.
3 tremors
A tremor is simple shaking or trembling of any part of the body. The
movements are usually not as pronounced as in myoclonus. It tends to be
most noticeable in the hands and often increases with stress, even in
children.
Essential tremor: This is the most common type and can be a condition in
itself, unrelated to any other disease. It is triggered by posture or
movement and produces uncontrolled trembling, often affecting the head
and/or speech.
Intention tremor: This occurs when beginning to make a movement.
Resting tremor: This means you're not moving but some muscles, especially
those in your hand, may still be trembling.
4 Not serious: Becoming exhausted and dehydrated through physical
work or sports or allowing blood sugar to drop too low (hypoglycemia), can
produce shaking and signs of incoordination. As long as these resolve with
rest, fluids, and food, it is not serious.
Moderately serious: Any other kind of tremor or involuntary movement should
be seen by a medical provider right away.
Serious: Anyone with a history of dystonia who is also undergoing physical
or emotional shock, such as surgery, injury, or the loss of a loved one, is
at risk for severe dystonia that can be life-threatening.

Q 5. Line between fractions is known as vinculum.
KR In mathematical notation, the vinculum is placed as an overline
or underline over or under a mathematical expression to indicate that the
expression is to be considered grouped together. It is most commonly used
to denote:
· A fraction: In a fraction, the vinculum separates the numerator
and denominator. For example, 𝑎𝑏*ba* is read as “a over b”.
· A radical: In a radical, the vinculum is placed over the
expression under the radical sign. For example, 𝑎+𝑏*a*+*b* is read as
“the square root of a plus b”.
· A complex number: In a complex number, the vinculum is placed
over the imaginary part of the number. For example, 𝑎+𝑏𝑖‾*a*+*bi* is
read as “a minus bi”, where the bar over the expression indicates the
complex conjugate.
· A repeating decimal: In a repeating decimal, the vinculum is
placed over the repeating digits. For example, 0.3‾0.3 is read as “0.3
recurring”.
Examples
Let’s take a look at some examples of how the vinculum is used in
mathematical notation:
· 𝑎+𝑏𝑐−𝑑*c*−*da*+*b* : In this expression, the vinculum
separates the numerator and denominator of the fraction. The expression can
be read as “a plus b over c minus d”.
· 𝑎2+𝑏2*a*2+*b*2 : In this expression, the vinculum is placed
over the expression under the radical sign. The expression can be read as
“the square root of a squared plus b squared”.
· 3+4𝑖‾3+4*i* : In this expression, the vinculum is placed over
the imaginary part of the complex number. The expression can be read as “3
minus 4i”.
· 0.6‾0.6 : In this expression, the vinculum is placed over the
repeating digits of the decimal. The expression can be read as “0.666
recurring”.
Overall, the vinculum is an important symbol in mathematical notation, used
to indicate grouping, fractions, radicals, complex numbers, and repeating
decimals.
WHY THIS WORD IN MATHS?
a connecting band of tissue, such as that attaching a flexor tendon to the
bone of a finger or toe. IS PURELY A CALL IN Biology. In maths in view of
the importance and connecting the principles of the Maths, this word is
used.

Q 6. Rubber band last longer when refrigerated.
KR SMDW: Not necessarily; generally, in hot weather it could melt;
or kept in normal weather, will work excellently But this idea of rubber is
based on the physical principle; not only Rubber, many get into that
principles. When rubber bands are stored refrigerated, the colder
temperature slows down the molecular motion within the rubber, preserving
its elasticity. The low temperature of the refrigerator helps to maintain
the stability of the rubber and slows the deterioration process, ultimately
prolonging the lifespan of the rubber band.

KR You only wrote few years back Lack of material is lack of Brain.
Q 9. Hippopotamus milk is pink in color.
KR C P is a joke when reproduced without know how as about.
*The pink hippo milk rumour has been spreading across the web for some
time, but it really gained footing in 2013*, when National Geographic
posted about the hippo's rose-coloured milk on both its Facebook and its
Twitter pages. Is the rumour true? Let's examine the facts.
Like all mammals, hippos (Hippopotamus amphibius) produce white or
off-white milk for their babies.
Despite this fact, it's easy to see where some of the colour confusion
comes from. Hippos have no actual sweat glands, but they do have mucus
glands, which release an oily secretion people frequently refer to as
"blood sweat."
Despite its name, this secretion is neither blood nor sweat; instead, it's
a blend of hipposudoric acid and norhipposudoric acid.
In combination, these two acids play an important role in the health of a
hippopotamus. They serve as a natural form of sunscreen and moisturizer for
the animal's sensitive skin, and they have antibiotic properties that
protect hippos from harmful bacteria while they're in the water.
That means hippos can live in some pretty toxic spots with minimal risk of
infection.
Now here's where it gets weird: This special secretion comes out colorless
like human sweat, but it turns to a bright orange-red in the sun so that it
looks like blood. A few hours later, it loses its blood-like luster and
shifts into a dirty brown color.
During the period that the hippo's secretions are at their orange-red peak,
some could mix with the milk, giving it a pinkish hue.
While this is possible, it's also pretty unlikely, as baby hippos are very
efficient eaters. A baby hippo grips its mother's nipple between the tongue
and the roof of its mouth, forming such a tight bond that it can even nurse
underwater if it wishes.
Reports of pink hippo milk are limited not only by the low odds that these
two fluids will mingle, but also thanks to the difficulty of getting a
close look at the hippo's feeding process. Female hippos are most likely to
attack when they are pregnant or taking care of their young, and few people
are brave enough to tangle with a mad 3,000-pound (1,361-kilogram) female
hippo just to get a glimpse of her milk.
Despite a lack of evidence to support the pink milk theory, this rumor
continues to spread; thousands of people have liked this fun "fact" on
National Geographic's Facebook page.
https://youtu.be/eRtBMHEngcA You Tube That means mom giving milk to baby
mixing blood is not red milk; Milk is always white only.
----------------------------------------------------------------------------
Q 10. There is no reason for this alphabetical order. (as A, B, C…)
KR I don’t know why this brilliance only with English alphabets?
All alphabets have no reason; but baby opens up with first alphabet only
with A OR SIMILAR SOUND IN ALMOST ALL THE LANGUAGES.
The Etruscan (language of ancient Etruria) alphabet, which was influenced
by the Western Greek alphabet, gave birth to Latin (Roman) script,
initially consisting of twenty letters and eventually gaining three more
(J, V and W) by the Middle Ages. Y and Z were introduced later from the
Eastern Greek alphabets.
[image: Evolution alphabet]Greek and Latin alphabets evolved over the
years. (Photo Credit : Druss/Wikimedia Commons)
As Latin and other forms of writing spread across Europe, various regional
scripts and letterforms arose to account for linguistic differences and
requirements of different regions. Some of these were accidental shifts
that arose from a desire to simplify or speed up the writing process.
English gets most of its capital letters from the Roman style of writing.
In the later Middle Ages, certain scripts developed in northern Europe that
formed modern-day lower-case letters.
And Sanskrit and Tamil and so many languages have similar patterns starting
from ancient period till date.

Q2 What are some psychological facts that people don't know?
Q1 and Q2 are similar but titles are grandiose.
Q 1. 90% of people will fake laugh when they don’t understand what
someone said to them.
KR Some time back there was a data on people who do not laugh. And
all don’t fake; there are always a set of people who feigns they know it;
so, they will utter some Brahminical language words before Mutts, prostrate
whosoever he is, and laugh as if understood. Helpless. But many do project
only the real emotions, there is no universal basis of such statement
anywhere.
Qc 2. The brain reacts to emotional pain the same way it does to physical
pain.
KR Again HASTY GENERALISATION. Stoic personality, diplomats, and
sthithapragnan who are in large numbers do not express what is their
emotion at all. Especially ladies’ expressions are unfathomable. Brain may
react but brain does not react to convey.
Q 3. Your perception of colour depends on the background.
KR Yesterday mind blowing was different; and my answer yesterday
change the preposition today. Colour is a MAYA and subjective to the
perception.
Q 4. The people who give the best advice are usually the ones with the
most problems.
KR I don’t know where such Vedanthas are transcribed. Another wrong
unproven fact. Even people after retirement without knowing to whiling away
time (which is not a problem) will keep advising. It is in nature. Some
enter only when asked; some enter always to say. Some rearranges the
damaged ports.
Q 5. Placebo works even when you know it’s a placebo.
KR Is that meaningful? Before the kid a grandparent may act knowing
fully well; can any one say Placebo works when truly knowing it’s a
placebo? Once you know it is a rope, will any one still think it as a
snake?
Q 6. Your most vivid memories are wrong.
KR It's a complex topic. While memories can sometimes be
inaccurate due to various factors like suggestion, bias, or the passage of
time, *not all vivid memories are necessarily wrong*. Some memories can be
vivid and accurate, especially if they're associated with strong emotions
or significant events. It's important to approach memories with critical
thinking and recognize that they may not always be entirely reliable. Thus,
HASTY GENERALISATION
Q 7. When crying happiness, the first tear will come from the right,
but if you’re crying from sadness it will fall from the left.
KR *There's no scientific evidence to support the claim that* tears
fall from one side or the other based on the emotion causing them. Tears
are produced by tear glands, and they typically flow down both sides of the
face. The direction of tears isn't typically associated with specific
emotions like happiness or sadness. Emotional tears are triggered by the
limbic system, the part of the brain that's involved in emotions, but they
don't follow a pattern based on the type of emotion experienced. So, the
statement you provided doesn't seem to be true based on our current
understanding of tears and emotions.
Q 8. While telling a lie, adding an embarrassing detail can make it
more believable.
KR An unsupported by Arthashastra but well supported by Goebel
Q 9. Lonely people end up sharing the most personal information on
social media platforms.
KR Correctio; ALSO.
Q 10. When you impress someone, they will often forget about what
they thought of you.
KR THERE IS NO SUCH BLACK MAGIC
Q 11. Nightmares help prepare people to deal with difficult
situations in real life.
KR Nightmares need counselling; Many soldiers of Vietnam
underwent treatments for long.
Q3 What are some mind-blowing facts you probably didn't know?
KR Another set of unfounded gossips
Q Your nose is always in your peripheral vision but your brain can
ignore it.
KR What is meany by vision, peripheral vision and perceptions which
brain can distinguish well. Brain imprints all that are seen even when you
were 5, which you think later, when reflected after, that so. Brain
photographs all seen. So peripheral etc are outmoded.
Q There are more atoms in one glass of water than there are glasses of
water in every ocean.
KR This statement is true but subjective because SMDW: This statement is
true, but it depends on the size of the glass and the volume of water in
the ocean. Let's break it down: The number of atoms in one glass of water:
A typical glass of water contains around 330 millilitres, which is roughly
18 sextillion (18 followed by 21 zeros) molecules of water. Each water
molecule contains three atoms: two hydrogen atoms and one oxygen atom. So,
the total number of atoms in one glass of water would be 3 times 18
sextillion, which is a very large number.
The number of glasses of water in every ocean: There are estimated to be
about 1.332 billion cubic kilometers (1.332 x 10^21 liters) of water in the
world's oceans. To calculate the number of glasses of water, we'd need to
divide this volume by the volume of a glass of water.
When you compare the number of atoms in one glass of water to the number of
glasses of water in all the oceans, the number of atoms in one glass of
water would indeed be significantly larger.
Q There was a moment when you were youngest person alive.
KR The statement is a bit paradoxical. It's implying that at some point
in your past, there was a moment when you were the youngest person alive,
meaning you were just born and had not yet been surpassed in age by anyone
else. While it's technically correct, it's not a particularly meaningful
statement since it applies to every person who has ever lived. When someone
is born, for a brief moment, they are the youngest person alive until
another person is born after them. So, while the statement is logically
sound, it's not particularly insightful or profound.
Q A baby born at 11 pm in California and baby born at 2 am in New
york, have different birthdays despite being born simultaneously.
Q We are closer to year 2033 than the year 2000.
KR ABOVE GOOD KADI JOKES
Q When you think about brain, the brain is actually thinking about
itself.
KR Metacognition allows us to monitor our own cognitive processes,
such as problem-solving, decision-making, and memory, and to evaluate and
regulate our thinking. For example, when you reflect on your own thoughts,
analyse your own emotions, or question your own beliefs, you're engaging in
metacognitive processes. So, in essence, the brain can think about itself
through metacognition. However, people deny the thoughts outside is a meta
function.
Q5 What are the most interesting facts you know?
Q 8. By the age of eighteen your brain stops growing.
KR: The brain undergoes significant periods of growth and development,
particularly during early childhood and adolescence. Here's a brief
overview:
Prenatal Development: Brain development begins very early in prenatal
development and continues throughout pregnancy. Neural tube formation,
neural proliferation, migration, and synaptogenesis occur during this
period.
Infancy and Early Childhood: After birth, the brain continues to develop
rapidly during infancy and early childhood. This period is characterized by
extensive synapse formation and pruning, myelination (the process of
forming myelin sheaths around nerve fibers), and the development of basic
sensory, motor, and cognitive functions.
Adolescence: The brain undergoes further refinement and maturation during
adolescence. This period is marked by continued synaptic pruning and
myelination, as well as the development of higher-order cognitive functions
such as abstract thinking, reasoning, decision-making, and impulse control.
Adulthood: While the brain continues to undergo some changes in adulthood,
the rate of growth and development slows down compared to earlier stages of
life. However, neuroplasticity, the brain's ability to reorganize and adapt
in response to new experiences, continues throughout adulthood.
It's important to note that individual differences in brain development
exist, and environmental factors, genetics, and experiences can all
influence the trajectory of brain growth. Providing a stimulating and
nurturing environment during critical periods of development is essential
for promoting healthy brain development.

> Would you believe a matchbox-size chunk of bone can support 18,000 pounds?
> Compared to concrete, human bone is four times greater in support strength.

> 7. Your skin is an organ.
>
> Just like the liver, heart, and kidneys, your outer covering is an organ.
> An average man has enough skin on his body to cover approximately twenty
> square feet. For an average woman it is approximately seventeen square
> feet. Approximately 12% of your weight is from your skin. And, your skin
> replaces 45,000+ cells in only a few seconds. It's constantly growing new
> skin and shedding old skin.
>
> 8. By the age of eighteen your brain stops growing.
>
> From that age forward it begins to lose more than 1,000 brain cells every
> day. Only two percent of your body weight is occupied by your gray
> matter, but is uses up to 20% of your overall energy output (it needs
> carbohydrates). Your brain works continuously and never rests, even when
> you're asleep. Aside from producing REM dreams, your brain works overtime
> to replenish its ability to function normally during your daytime waking
> hours.
>
> 9. There are more than 600 individual skeletal muscles and 206 bones in
> your body.
>
> If all 600+ muscles contracted and pulled in the same direction, you could
> lift over twenty tons of resistance. Additionally, the adult skeleton is
> composed of 206 bones, but at birth an infant skeleton contains
> approximately 350 bones. Over time, some of the 350 bones fuse together and
> eventually grow to the 206 adult figure.

> 10. You need to consume a quart of water each day for four months to
> equate to the amount of blood your heart pumps in one hour.
>
> Additionally, over a lifetime, at your normal (resting) heart rate you
> will have pumped enough blood to fill thirteen oil super tankers. To
> further expound on this fact, on average, your heart beats 40,000,000 times
> per year. Doing the math, over your lifetime (both men and women averaged),
> that results in 2,600,000,000 heartbeats (two billion, six hundred
> million). This does not even factor in your increased heartbeats due to
> your love of exercise
