Q3     Already I denied the Chinese printing press as well as the paper
productions. Still from somewhere the erroneous data again purged in as I
read Mr VG. Had he read the authentic book I gave ( MR G Because I said it
is not perfect; I analyse the perfection; so it is perfect) China never had
any scientists as being challenged in the Sri VG article; always till date
they were stealing the products of others. China gained so much money by
suppressing the people , they were able to do cut throat business. Even
today the jungle alone is enforced. In the meantime, the books were taken
from Nagarjuna, The buddhist when chinese visitors came to India;
paper technology of India on mantle and paper were stolen from India; the
printing press mechanical was stolen from Germany; The history of china
written by the chinese -american speaks a lot. An Indian research paper
accepted at the international level in 2021 authoritatively confirms it. I
had written about it recently also. People like Gm N and some more like VG
etc if they don't wish to read that is a different issue; but in order to S
O S of his friend ,let him not offer wrong information.
"Northern humanists were profoundly devoted to ancient learning but nothing
in northern humanism compares to the paganizing trend associated with the
Italian Renaissance. The northern humanists were chiefly interested in the
problem of the ancient church and the question of what constituted original
Christianity.

Two factors operated to accelerate the spread of Renaissance culture after
1450: growing economic prosperity and the printing press. Prosperity -- the
result of peace and the decline of famine and the plague -- led to the
founding of schools and colleges. In these schools the sons of gentlemen
and nobles would receive a humanistic education imported from Italy. The
purpose of such an education was to prepare men for a career in the church
or civil service.

Sometime in the 13th century, paper money and playing cards from China
reached the West. They were "block-printed," that is, characters or
pictures were carved into a wooden block, inked, and then transferred to
paper. Since each word, phrase or picture was on a separate block, this
method of reproduction was expensive and time-consuming.[ I had spoken
under Q3 about it which is manual and it is not a printing machine. It is
like rubber stamping done manually. ]

The extension of literacy among laypeople and the greater reliance of
governments and businesses upon written records created a demand for a
less-costly method of reproducing the written word. The import of paper
from the East as well as "block-books" (see above), were major steps in
transforming the printing of books. However, woodcuts were not sufficiently
durable as they tended to split in the press after repeated use.
Furthermore, a new block had to be carved for each new impression, and the
block was discarded as unusable as soon as a slightly different impression
was needed.

By the middle of the 15th century several print masters were on the verge
of perfecting the techniques of printing with movable metal type. The first
man to demonstrate the practicability of movable type was Johannes
Gutenberg (c.1398-1468), the son of a noble family of Mainz, Germany. A
former stonecutter and goldsmith, Gutenberg devised an alloy of lead, tin
and antimony that would melt at low temperature, cast well in the die, and
be durable in the press. It was then possible to use and reuse the separate
pieces of type, as long as the metal in which they were cast did not wear
down, simply by arranging them in the desired order. The mirror image of
each letter (rather than entire words or phrases), was carved in relief on
a small block. Individual letters, easily movable, were put together to
form words; words separated by blank spaces formed lines of type; and lines
of type were brought together to make up a page. Since letters could be
arranged into any format, an infinite variety of texts could be printed by
reusing and resetting the type.

By 1452, with the aid of borrowed money, Gutenberg began his famous Bible
project. Two hundred copies of the two-volume Gutenberg Bible
<http://prodigi.bl.uk/gutenbg/default.asp> were printed, a small number of
which were printed on vellum. The expensive and beautiful Bibles were
completed and sold at the 1455 Frankfurt Book Fair, and cost the equivalent
of three years' pay for the average clerk. Roughly fifty of all Gutenberg
Bibles survive today.

In spite of Gutenberg's efforts to keep his technique a secret, the
printing press spread rapidly. Before 1500 some 2500 European cities had
acquired presses. German masters held an early leadership, but the Italians
soon challenged their preeminence. The Venetian printer Aldus Manutius
published works, notably editions of the classics. [ Few of us are trying
to decode a text which if clicked press may be here ahead of germany]  KR

2  Another error in electric light by chinese? Maybe inventions that
changed the world book extract? It is  not clear. Any way the On March 31,
1880, Wabash became "the first town in the world generally lighted by
electricity," as four 3,000-candlepower Brush lights suspended from the
flagstaff on top of the Wabash County Courthouse were switched on, flooding
the neighborhood with light. (USA) . But it was not Edison who invented but
did form a team to invest and start the manufacturing. Before that there
were arc lamps and 26 inventors before Edison. According to David Burkus,
the author of “The Myths of Creativity,” he was actually the 22nd or 23rd
person to invent it, depending on how you count. Not only did Edison not
invent the light bulb – as we're all taught in school – he also wasn't this
“lone genius” dreaming up endless amazing inventions by himself.

3       Again China has nothing to do. On January 29, 1886, Carl Benz
applied for a patent for his “vehicle powered by a gas engine.” The patent
– number 37435 – may be regarded as the birth certificate of the
automobile. In July 1886 the newspapers reported on the first public outing
of the three-wheeled Benz Patent Motor Car, model no. 1.(Germany before
division)

4     Again China had nothing to do. Before Bell, "While Italian
innovator Antonio
Meucci  is credited with inventing the first basic phone in 1849, and
Frenchman Charles Bourseul devised a phone in 1854, Alexander Graham Bell
won the first U.S. patent for the device in 1876."Italy and France did it
but Patent was taken by Bell so by back door Graham bell became the
first. Alexander
Graham Bell is credited with being the inventor of the telephone since his
patent and demonstrations for an apparatus designed for “transmitting vocal
or other sounds telegraphically… causing electrical undulations” were
successful. First Bell Telephone, June 1875.

Q4      The Chhandogya Upanishad

1.   LIFE HACK: a strategy or technique adopted in order to manage one's
time and daily activities in a more efficient way.

But it is hacking sir not helping. K R IRS 10 7 23

1.   If one sleeps on right side, will fall asleep faster than sleeping on
the left side.

KR      No basis sir; I sleep faster only on left than the right .

2.   Using non-dominant hand for mundane tasks, like eating or opening
doors, for two weeks can improve your self-control.

KR    No proof and not even basis of Psychology sir

3.   Being hungry also helps one to make better decisions.

KR        Again unscientific and non-Vedic.  Fasting is good for the
upliftment of spiritual, mental, physical, and emotional strength.  Not for
decisions.

*1. Annam asitam tredha vidhiyate, tasya yah sthavistho dhatus tat purisam
bhavati, yo madhyamas tan mamsam, yo’nisthas tan manah. *

The food that you eat is converted into three forms. What happens to the
food that is eaten? There is a gross form of the food, there is a middling
form of the food and a subtle form of the food. The food that we eat is not
entirely absorbed into the system. Some part of it is thrown out as
excreta, as unwanted material which cannot be absorbed into the system. It
is refuse that goes out as undesirable to the system; that is the grossest
form. So one part of the food goes out; something else only is absorbed.
That something else other than that which is thrown out has again two
aspects, the very subtle vibratory aspect and the middling form of it. That
which is middling is absorbed in the form of flesh in the system. The flesh
in the body is due to the entry of the middling quality of the foodstuff
that we take. But the highly subtle form, the vibration that is produced by
the essential quality of the food, influences the mind itself. So you know
your mind, your capacity of thinking, the way of thinking, will be very
much influenced by the food that you take, continuously, of course. If you
go on eating the same kind of food for years together, that quality of the
food will tell upon your psychological pattern. So, the gross thing is
thrown out, the middling form is absorbed into the fleshy part of the body,
and the subtlest part goes to the mind. The mind feels happy on account of
absorption of some part of the food that we eat. These are the three
aspects, the three degrees of the intensity of the food that we see, that
become parts of our system in this manner. Likewise, the water that you
drink has a gross aspect, a middling aspect and a very subtle aspect. Any
liquid that you take also is divided into three parts.(chandogya 5 1 }

4.   Listening to music for at least 5-10 minutes a day makes it easier to
deal with emotional stress.

KR  It is true; but any diversion will do that and Music is one; even while
studying change of subjects , periodically it rests and enforces the
absorptions.

5.   Video games are more effective at battling depression than therapy.

KR       Pl read this; nandrum theethum pirar thata vaaraa. “: SOCIETY FOR
PSYCHOLOGY: It is commonly believed that video games are inherently
unhealthy for individuals and for society as a whole. For example, a recent
statement from the US President linked video gaming to extreme violence and
mass shootings in the United States:

“We must stop the glorification of violence in our society. This includes
the gruesome and grisly video games that are now commonplace,” President
Trump said. “It is too easy today for troubled youth to surround themselves
with a culture that celebrates violence. We must stop or substantially
reduce this, and it has to begin immediately” (Timm, 2019).

This statement is consistent with the troubling image of a lonely,
depressed male gamer playing, perhaps, in his mother’s basement. According
to conventional thinking, this gamer ignores daily responsibilities, plays
obsessively, and has no romantic relationships or relationships of any kind
outside of the virtual video game world. This pathologically addictive
gaming behaviour then has only negative effects, such that he might be
depressed or socially anxious. He may play violent video games for hours on
end, which leads to increased aggression and anger levels. This anger is
then directed elsewhere, such as a mass shooting that ends with his death,
either by his own hand or that of the police with a ‘suicide by cop’. For
‘typical’ people who enjoy playing video games (such as the present
author), these anecdotal beliefs and mental images are offensive and
disturbing and, moreover, often inaccurate.

Indeed, video games reach a much wider population than the lonely male
gamer of the vignette given above. According to recent gaming census
information, there are close to 2.3 billion video gamers globally, nearly a
third of the world’s overall population, with an estimated global revenue
of 151.2 billion US dollars in 2019 (Game Gavel, 2019; Newzoo, 2019). The
gender and age distribution are also quite different from anecdotal
beliefs, such that 46% of gamers in the US are female (Entertainment
Software Association, 2019) with 31% of gamers worldwide being 18-35 years
old, 37% being older than 36, and only 32% being under 18 (Game Gavel,
2019). These recent statistics certainly shake the notion that it is only
adolescent or young adult males that play video games; rather, the
population is much more diverse than previously thought.

Our recent comprehensive literature review aimed to focus on video games in
a positive light in order to determine what benefits they can have for
various aspects of well-being. Specifically, we examined games with social
aspects, physical activity, and the presence of violence to see how these
factors of video games can be beneficial to well-being.

Firstly, video games that include social components have shown to have
positive benefits on both prosocial behaviour and psychological aspects of
well-being (e.g. Herodotou, Kambouri, & Winters, 2014; Jin & Li, 2017). For
example, a study involving school children concluded that prosocial video
games were significantly related to the ability to cooperate, share, and
maintain positive relationships with each other outside of the game
(Harrington & O’Connell, 2016). Further, online social games might be a
possible alternative social outlet serving a similar function to in-person
contact for players (Kowert & Oldmeadow, 2015). This is potentially
positive, as this video game social interaction might promote enjoyable
social contact for those with remote locations, psychological difficulties,
or other factors that can inhibit in-person interaction (Odrowska & Massar,
2014).

Secondly, we argue that the full picture of the relationship between
violent video games and aggression may be mixed, as confounding variables
may have impacted some of these effects. For instance, previous research
has shown that family and social variables as well as the motivation behind
the violence are more significantly related to an increase in aggression
than the violence itself (Ferguson et al., 2015; Gao, Weng, Zhou, & Yu,
2017; Sauer, Drummond, & Nova, 2015). Further, violent video games can also
be played with a social aspect which in turn alters the effect that the
game has on well-being. Research here has demonstrated that adding a
prosocial aspect to the game, such as protecting another character – either
one controlled by another player or an NPC – can increase prosocial and
helping behavior (Gitter, Ewell, Guadagno, Stillman, & Baumeister, 2013;
Velez, Greitemeyer, Whitaker, Ewoldsen, & Bushman, 2016; Velez, Mahood,
Ewoldsen, & Moyer-Guse, 2014). Additionally, players of both violent and
non-violent video games had increased prosocial behaviors with the
inclusion of cooperative gameplay when compared to solo gaming, (Jin & Li,
2017) alluding to potential benefits of adding prosocial aspects to any
genre of video game.

Lastly, there is a growing body of research demonstrating the impact of
video games that require the player to interact physically with the game in
order to control an on-screen character, commonly referred to as exergames.
For example, studies show that engaging in an exergame regime significantly
improves balance, flexibility, braking force, lower limb muscle strength,
maximal oxygen levels, and heart rate, (Maillot, Perrot, Hartley, & Do,
2014; Nitz, Kuys, Isles, & Fu, 2010; Roopchand-Martin, Nelson, Gordon, &
Sing, 2015). Additional experimental studies demonstrate that when
comparing an exergame to traditional exercise, exergames lead to
significantly higher levels of enjoyment (Monedero, Lyons, & Gorman, 2015;
Strand, Francis, Margrett, Franke, & Peterson, 2014), alluding to the
possibility of a higher adherence rate when compared to traditional
exercise.

Overall, this review concluded that the ways in which video games relate to
well-being are nuanced and moderated by individual and socio-contextual
factors. This includes the presence of social aspects, violence, and
physical activity, though these positive effects are only seen when games
are played for enjoyment purposes rather than for obsession. Video games
themselves, then, are not dichotomous in terms of being positive or
negative, but rather, the relationship between video games and well-being
is determined by a combination of a multitude of factors. It is our hope
that moving forward we can help to shake the notion that video games are
inherently bad for individuals and shed light on how they can be beneficial
to well-being.

7.   Washing   hands; makes one more optimistic.

KR      No related evidence; Sigmund Fraud says that anyone washing hands
often, in the normal circumstances, is a culprit, committing a crime.

8.   While cleaning a room, start with making the bed first. It will make
everything around it look out of place and it will motivate one to be clean
always!

KR       Again no evidence. Most toppers and administrators and the Kings
who had UNKEMPT soaace , raided the earth.

10.                Being a perfectionist can result in stress and
depression.

KR         What is meant by perfectionist?  No dharmic perfectionist would
have stress as he knew the meditation.

11.                People who sleep late have more mental stamina and can
outperform early risers.

KR          Contradicting 9. Sleep requirement is a variable factor. Body
knows how much.

12.                Studying for 30 to 50 minutes at a time (with 10-minute
breaks in between) is the most effective way to retain information

KR          No way; any change of work is scientifically proved; the
sagging brain is energised; even change of study from Physics to chemistry
refreshes the Brain.

13.                Eating food without preservatives can improve I.Q by up
to 14%.

KR             No way

14.                Simply looking at a photo of someone you love can help
to relieve pain.

KR           Photo is not; attention diversion.

15.                Dancing often increases happiness.

KR          Depends on your choosing the hobby; anything including the
Dance.

> The pineal gland or epiphysis is a chronobiotic agent. *This means that
> it synchronizes our internal clock with the light-dark cycle*. In the
> absence of light, this small brain organ of just 120 milligrams produces
> the hormone that takes us to the world of dreams: melatonin.
>
> *In some animals (fish, reptiles and amphibians), this gland is located
> under the skin and is able to receive light information directly. For this
> reason, it* is also known as the "third eye".
>
> However, in the human species, as in most vertebrates, this
> pineapple-shaped and pea-sized organ is located inside the skull.
> Therefore, more complex ways are needed to know whether it is day or night.

> Jenna petted Albert without love, and in a way he really didn’t like
