 Not only that- If a tender coconut while bringing down and  touch the head of 
a person, and accidentally falling the bunch down on a person, the effect  is 
different. Both will have different effects depending on the time taken

Thanks.
Although NOT DIRECTLY related to Q 1 let me share this, nevertheless.
Einstein's Theory of Relativity was explained with this example of time.
When you wait for your lady love to arrive even 10 minutes seems to be an hour
or even longer.
But when you spend time with her discussing things, even an hour seems to be
less than 10 minutes.
Time is the same but our perception of it makes the difference.
In Marketing they say it does not matter how good your product really is BUT
how people perceive it only matters.
Coming back to Time, Paradoxically only a really busy person finds time to all
the things that matter - prioritizing things.
Time is a scarce resource for him and he tends to use it wisely and optimised
its use. (Modi is an obvious example - how he packs so many events in his
schedule is a wonder).
While a lazy fellow who has all the time in the world never fulfils any thing -
procrastination and lethargy.
This only goes to prove that ANYTHING we have in EXCESS we tend to waste. This
is a general rule and there could be exceptions.

CULTURAL QA 04-2024-22

All the BELOW QA are from Quora digest to me on 22-04-2024.

Quoraanswers need not be 100% correct answers

.Compiled andposted by R. Gopala krishnan, on 22-04-2024

Q1 Can science explain why timeappears to be passing faster nowthan
in the past?

A1 Hilary,Fri

Time can appear to be going by faster than in thepast, but this doesn’t mean
that it’s actually going faster, so scientistswouldn’t be the ones to ask. An
hour, a day, a week, a month, and a year are nodifferent than they ever were.
Time can drag when we’re not interested in lifeand busy with activities, and it
can fly when we are involved with ouractivities. We all know how an hour can go
by like five minutes if we’reenjoying ourselves, and five minutes can seem like
an hour if we’re bored.

Psychologists might say that some people feel thattime is going by faster than
it was in the past. it might be because ourtechnological society doesn’t give
people as much time for just sitting anddoing nothing. Relaxing and doing
nothing can make it seem as though time isgoing more slowly, which can be to
our benefit, even if it doesn’t seem so,especially if we feel bored. In our
modern society when hardly anyone wants tobe “unplugged,” perhaps time seems to
be flying by.

Q2 Is there a scientific explanationfor why humans enjoy hearing
stories?

A2 Don Gregory ,been there ... too many times ...Apr 15

Starting from the viewpoint that we (humans, brains)are ‘prediction’ systems
(discussed at length elsewhere) … what stories do isto provide more information
for our brains to use in makingdecisions/predictions, without having to “live”
the real-life situationsdescribed in the stories.

This way, the brain hopes that, should we ever getinto a similar situation, we
might have some better information we can use tohelp us in that situation. (all
that’s the ‘scientific’ part … now for somemore fun thoughts)

Even fairy-tale types of fables … they’re not to helpus should we ever find
ourselves in a cottage, in the woods, made ofgingerbread and candies … but the
indirect message on how to listen to ourelders, be wary of strangers and most
importantly, don’t go roaming into thedark forest just because your parents
won’t buy you your own cell phone!

All useful information on how to more successfullynavigate the complicated
world we call home.

(having saidall that, I note that it’s highly unlikely that the OP, the quora
promptgenerator, will ever find itself in a dark forest … but you never know)

Q3 Why is gravity called a 'theory'and not a fact?

A3 SteveBaker ,Senior Software Engineer(2013–present)Sun

This is a common misconception.

There are many words that we use in everyday speechthat have different meanings
in the language of science.

INTRODUCTION TO SCIENCE-SPEAK:

So you use the word “Accelerate” to mean “Go faster” -but to a physicist - it
means “change speed or direction” - could be faster,could be slower - could
mean the same speed - but changing direction.

So - the word “Theory” (which could mean ‘Half-assedidea” in common English)
means “The very best idea we have of what the factsare.” in science-speak.

And that’s true here. “The Theory of Gravitation” isthe encapsulation of our
knowledge of how Gravity works.

Same deal with “The Theory of Evolution”, “Theory ofRelativity” and so forth.

When scientists want to talk about an idea that’s NOTproven - they use the word
“Hypothesis”.

So we talk about things like: “The SimulationHypothesis”…it’s the interesting
idea that the world is actually just acomputer program being run by some kind
of crazily advanced alien.

They also use the word “Law” - to mean something similarto a “Theory”. So you
get “Newton’s third Law of Motion”.

MATH-SPEAK:

Mathematicians also have different words - they use“Conjecture” to mean what
scientists call a “Hypothesis”…and a “Theorem” wherephysicists would use “Law”.

THESE SPECIALIZED FORMS OF LANGUAGE ARE VERY COMMON:

Nearly every discipline in the world - from bricklaying to quantum cryptography
develops it’s own version of our variouslanguages.

I work in Computer Science - we describe a problem as“Trivial” - meaning it’s
very easily solved.

But when we say “Non-trivial” we don’t mean that it’smerely not-trivial - we
mean that’s it’s very nearly impossible (and maybeACTUALLY impossible).

Q4 Are there any scientific theoriesthat challenge or contradict
Darwin's Theory of Evolution? If so, how do theyexplain the existence of humans
today?

A4 StevenMatish, Lives in The United States of America
(1984–present)Apr 13

First of all, Darwin was NOT a scientist. He went tomedical school, then
dropped out cuz he couldn’t stand blood. His only degreeis in theology! He went
to divinity school, but never became a pastor. Instead,he decided to be a
professional!!

“Only thefittest survive and pass on their genes.” This is NOT a scientific
theory. Itbegs the question. Survival is not a test of fitness. I could design
anexperiment proving that shit happens, and sometimes the fittest are just at
thewrong place at the wrong time!!! And the fittest in war, the most
capablesoldiers, get the toughest missions, and as a result are likely to get
killed.Therefore, the weak ones survive!! The less intelligent ones.

“On the sixthday, God created man.” -Genesis.

God is a quickening spirit. That means, he literallythinks things into
existence. Mankind was in the heart of God from thebeginning. So, God basically
willed us into existence. Not out of nothing,rather out of something abstract.
Thought of God. from the Heart of God, wecame to be.

Q5 Do any countries possessanti-gravity technology or flying
saucers similar to those depicted in science fictionmovies?

A5 ErnestCarrott Junior,Former Former Illustrator and Cartoonist
Apr 16

Anti-Gravity: To all intents this is a science fictionconcept. Now there are
cosmologists that have suggested that anti-gravity doesindeed exist and that it
does explain why and how the universe is expanding andthere is a view that to
every positive there is a negative, so we have positivegravity that attracts
and negative gravity that repels or pushes. However Isuspect if anti-gravity as
in science fiction movies and books for that matterthen we would have seen much
development in technology already. Withanti-gravity we could have very large
space stations as it would be possible tobuild large structures on Earth and
then using A-G we would be able to putthese into space and assemble even larger
structures, these we could give spingravity. Here on Earth we could have
aircraft both fixed and rotary wingedflying faster and further and needing less
fuel, we might even get air carsthat would be really effective, imagine this,
an air car that had a micro jetengine and A-G, if the engine were to cut out it
would not crash and if the A-Gwere to falter one would be able to bring the
vehicle down without it falling.

Flying Saucers: No, this was tried back in the 1950’sI think and really none of
the vehicles were viable options to what alreadyexisted in air vehicle designs,
nothing has really changed of course, now if wehad anti-gravity…

Conclusion: None of the novel tech exists as far as Ican see, if we had it,
then there would be major changes/improvements to ourlives already but there is
no evidence that such tech exists. Now it does notmean that it can’t happen but
it will not be in the coming decade or even inthe coming century so I think
not. But take into account I’m not a scientist;there may at time of writing be
breaking news, it maybe that a break-thru hasbeen achieved in one or both
fields of technology and that I have been provedvery, very wrong.
