INTERESTING QA- BASE QUORA DIGEST-Compiled
Q1 Why did early bicycles have a large wheel in front and a
small wheel in back?
KR Are there any inventions which concept due to some thoughts
and the making of the designs only, were first released, which changed
later by availability of technology developments later? Better to avoid
such questions since asking why in Rigvedam the lady grind in rocky tool
and did not use the grinder today?
Big wheels in vehicles like bicycles were originally
designed to improve efficiency and speed. The main reason for larger
wheels, especially in early bicycles (like the "penny-farthing" design), was
to *cover more ground with each rotation, which helped to increase speed
with less pedalling effort.* Larger wheels also made it easier to navigate
over rough terrain, as they could roll more smoothly over obstacles like
bumps or uneven surfaces. For bicycles, larger wheels provided a more
stable and efficient ride, especially when combined with the development of
rubber tires, which offered better grip and comfort. Over time, though, as
technology advanced and new designs emerged, smaller wheels became more
common for practicality and safety reasons.
Q2 What are some common health concerns for senior citizens?
KR Now fully understands that the compiler has a memory loss
and so only gets wild when pointed out. Drinking water and going to
hospital appeared already where grass has grown. Is it a common health
concern? Everyone, without prejudice to sex and age, must remember what
suits them; what is their capacity; what is their limitations; and what
really they are; and behave accordingly. Paranasivan kazuthil Irunda Paambu
kettatu; Garuda sowkyama?; Irukkum idathil everum irundaal yadum sowkyame;
Garudan sonnadhu. So self-realise and keep the tail tucked in, Then many
problems will be solved. That old would have drunk so fast pushing head
back where water might spill inside the nse also and could have been
choked. Why do you do that? Senior citizens only will become sick assured
as they are on the other side towards the grave. And therefore, let them do
without competing foolishly, what are their limitations. There was a case
long, long ago, where a senior citizen, after consuming an aphrodisiac ,
went for play a game and was admitted to the hospital; so can we write
about it? Health-conscious actions I gave a couple of days back and that
is THE END.
Q4 Since humans can’t eat raw meat, how did we ever survive
before we learned to control fire?
KR Another imaginary, unproven as we do not know, stupid Q and
A. One thing is certain time immemorial. Earth consumed all as food. Food
is, was and will only be a concept to appease hunger and survival. The food
intake might even be just leaves, fruits etc from the trees; may be after
the fire invention chikki- mukki etc, accidental fall of animal fat, when
touched the taste bud, might have tasted better and so consumed; or even
eaten raw as stomach is a good graveyard with the Agni. After all, when TN
had iron in 4000 BCE could not have had fire? So, why would Iyer worry
about NON-VEGETARIAN FOOD? And repeating it “N” times followed by 4A also?
Q4A What methods did early humans use to make fire and how did they
learn about these?
KR Another stupid question, in continuation. If the world was
burning for a million years and cooled off only after a million years (how
the years were calculated as a villager says “5 kal tolaivu pogonongo? So,
fire was there and easy to create also. What was there, might have been
discovered. And instead, may read our scriptures so that we get better
answers.
Q5 Can you tell some Extremely interesting facts
1 On a train ride, Polish mathematician Waclaw Sierpinski was worried
that he had lost a suitcase.
“No, dear!” his wife said, trying to reassure him, “All six suitcases are
here, right before your eyes.”
“That can’t be true,” the mathematician replied, “one is certainly missing,
I counted them several times: zero, one, two, three, four, and five.”
This story about a mathematician on a train is presumably apocryphal
(although, in fact, mathematicians apparently prefer to count from zero to
one) but this one about a physicist on a train is not.
2 Einstein was once traveling from Princeton on a train when, at a certain
point, the conductor approached him and asked him to show his ticket.
The physicist looked in his vest pocket, but the ticket was not there. So,
he looked in his pants pockets.
But there, too, was nothing. Then he looked in his briefcase, but there was
no sign of the ticket.
Finally, rather agitated, he looked at the seat next to him. No way, he
just couldn't find the ticket.
“Dr. Einstein, I know who you are. We all know who you are,” the conductor
tried to reassure him.
“I'm sure you bought the ticket. Don't worry.”
Einstein nodded appreciatively.
The conductor continued his work with the other passengers in the carriage
and as he was getting ready to move on to the next one, he turned around
and saw Einstein with his hands on his knees, looking under the seat,
desperately searching for his ticket.
Rushing back, the conductor shouted:
“Dr. Einstein, Dr. Einstein, you don't have to worry! I know who you are.
No problem, you don't have to show me the ticket. I'm sure you bought it!”
Einstein looked at him and said, “Young man, I also know who I am. What I
don’t know is where I’m going.”
KR COMPILER GOT INTERESTED SO HAVINGA TAG.
1 There is a Paramartha guru story; written even before suitcase
interest; the Guru wanted the shishya to check all the six reached the
other side of the shore and so asked him to count; every time he counted he
reported he reported one less only; Guru got angry; so he told him to count
the sound of beating each one with a stick; and when he beat all the count
became a right one; the foolish shishya was counting all without including
him. Thank GO an interesting fact after the beating.
2 While it's a charming story, there’s no concrete evidence that it
ever really happened. It may have been invented or embellished over time as
part of the lore surrounding Einstein's absent-minded genius. It’s a good
illustration of the human side of Einstein, though—his intellectual focus
was so intense that he sometimes didn’t pay attention to everyday details.
But ultimately, there's no proof the incident actually occurred as told.
FAKE.

*INTERESTING QA- BASE QUORA DIGEST-**Compiled*
*Q1 Why did early bicycles have a large wheel in front and a
small wheel in back?*
A1 Loring Chien, sometime bicycle rider1y
Bicycles are rated by the travel they take you with one turn of the pedal.
Too high a number required large pedal effort, , and too low a number
required low pedal effort but a lot of fast cranking to reach a reasonable
speed.
*It turns out that the optimal travel per pedal turn with direct connection
of the pedal to the wheel required a rather large wheel*, the kind you see
on old bicycles, called the penny farthing. Its simple, but the desired
circumference made the radius almost equal to the stride length of people…
making them sit on a seat perched just over the large front wheel. It made
it hard to mount the bike, hard to turn the wheel very sharply to steer,
and not able to get larger travel per turn as stronger bikers wanted.
These wheel diameters ranged up to 60″ but was usually limited by the leg
length (floor to crotch distance) of the rider.
So eventually bicycle makers learned to put a large pedal gear and a small
sprocket gear connected with a chain to amplify the travel per pedal by
making a smaller rear wheel turn many times per pedal rotation and *that’s
how we got the present two wheel bikes with wheels of equal size. *
Mechanisms to change the gears use allow even greater choice of speed vs
effort for experienced bikers. Something the penny farthings could not do.
*Q2 What are some common health concerns for senior citizens?*
A2 Gopalkrishna Vishwanath, While others "know" about ageing, I
have experienced it. Still am.5h
I received this in a WhatsApp forward and felt it should be widely shared.
A senior citizen of 62 years of age was admitted to the hospital for
choking in his lungs after drinking a glass of water at 11:00 pm. He was
rushed to the hospital for emergency treatment but unfortunately died. His
sudden death tells senior citizens that no matter what they do, they must
pay attention to two things:
One is to Prevent Falling,And the other is to prevent choking.
After 60 and beyond, one has to begin to train themselves.
When drinking water -
Stop everything and concentrate on drinking water carefully and slowly.
The elderly are prone to choking because the throat and swallowing muscles
have degenerated and lack muscle strength.
The following information is passed on by a doctor who is still active in
the medical field. It is worth referencing, especially if you or your
relatives or friends have become elderly.
Pneumonia caused by choking on drinking water, milk, soup, etc., which is a
common problem among the elderly.
If there are elderly people at home.
Please Note:
1. Use a straw, if possible, while drinking water, and keep your head down
when swallowing.
2. Please drink thick soup instead of clear soup. Clear soup flows quickly,
and it is easy to choke when breathing is not smooth.
3. Please do not drink liquid while there is still solid food in your mouth
or while chewing. If the water stays in the mouth for too long, it will
flow into the trachea and cause choking if you are not careful.
4 Do not speak or turn your head when there is food or water in your mouth.
5. Old people do not have the same physical strength and endurance as young
people.
If liquid or food enters the trachea and is coughed out, the face will turn
red and the blood pressure will soar. Sometimes choking can be fatal.
As we get older, we must drink water slowly, attentively, and cautiously.
*Q3 Can you tell a cat joke?*
A3 Richard Strachan, 2y
A cat died and went to Heaven. God met the animal at the Pearly Gates and
said, “You have been a good cat all of these years. Anything you want is
yours for the asking.”
The cat thought for a moment and then said, “All my life I lived on a farm
and slept on hard, wooden floors… I would like a real fluffy pillow to
sleep on.”
God said, “Say no more.” Instantly, the cat had a HUGE fluffy pillow.
A few days later, 12 mice were simultaneously killed in an accident and
they all went up to Heaven together. God met the mice at the Pearly Gates
of Heaven, with the exact same offer that He made to the cat.
The mice said, “Well, we have had to run all of our lives… from cats, dogs,
and even from people with brooms. If we could just have some little
roller-skates, we would never have to run again.”
God answered, “It is done.” All the mice had beautiful little roller-skates.
About a week later, God decided to check on the cat… He found her sound
asleep on her fluffy pillow. God gently awakened the cat and asked, “Is
everything okay? How have you been doing? Are you happy?”
The cat replied, “Oh, everything is just WONDERFUL… I’ve never been so
happy in my life! My pillow is always fluffy and those little
“Meals-on-Wheels” that You have been sending over are delicious.”
*Q4 Since humans can’t eat raw meat, how did we ever survive
before we learned to control fire?*
A4 Tomaž Vargazon, Practicing atheist Mon
Quite a few people seem confused by when humans mastered fire. One group of
vegans I occasionally stalk for meme content is convinced humans began
using fire around 4000 B.C.E.
Roughly this time period, I suppose
*The truth is of course humans have been using fire since before homo
sapiens arose*, looked to the skies and began to sing tuneful and
reflective songs on the subjects of peace, justice, morality, culture,
sport, family life and obliteration of all other life forms.
Indeed the earliest attempts at using fire by the genus homo dates back to
1.7–2 million years ago. The earliest evidence of widespread usage of
controlled fires by the genus homo dates back 1 million years and this is
not really in much dispute. Anatomically modern humans first appear 300,000
years ago.
Yes, this means earlier forms of humans used fire for twice as long as we,
homo sapiens, even exist. This means modern humans never had to deal with
any problem without having fire. Indeed, our evolution was shaped by having
fire in the first place.
We can eat raw meat still of course and often do: many cured meats are
eaten raw, steak tatare is raw, sushi is raw fish and so on. We still can
do it, but we long since evolved to do something more efficient instead.
*Q4A What methods did early humans use to make fire and how did
they learn about these?*
A4A David J. Hughes,Former Research Technician
Petroleum/petrochemical (1975–2013)10h
For the longest time, they used found fire. From a burning tree struck by
lightning, a grass fire, a volcano, whatever. *Then they kept it going as
long as possible.*
Having the tribal fire go out was a disaster.
They might be able to trade another group for a burning brand, or steal one.
Their ancestors had been making stone tools for at least half a million
years before the use of fire became common. Perhaps a stone worker noticed
that some rocks could produce sparks. Combining that with the trial and
error methods that had been developed for keeping fires lit. They tried to
direct one of those sparks into a mass of dry tinder.
*Or someone using a hand or bow drill noticed that the ends of the drill
got hot, maybe ht enough to produce a smoke smell, and thought ‘Can I get
it hot enough to start a fire?’*
*Q5 Can you tell some Extremely interesting facts*
A5 Alessandro13,11h
