Q1 How do trees that grow on a hill or mountain know to grow
perpendicular to level ground?
KR: Mr Gopalakrishnan finds always fulty answers as good given by
pofssors; and when his answer is scientifically pointed out, he says that
it is a thrash. For example, if there is a question why we do not fall (Mr
G is soeaking about the tree 2nd time and fall many times) does not all
know gravitation or akashana shakthi? Does it require a professor? So trees
are governd by GRAVITA AXIS AS THE ONLY REASON WOULD MAKE THE SCIENTISTS
LAUGH LOUD. WHY?
"Gravita Axis" isn't a widely recognized term in science or common discourse.
It could refer to concepts in physics or astronomy related to gravity and
axes of rotation, but without specific context, it's hard to provide a
precise definition. That is tree growing erect is only due to gravita-axis
is not such a gravita0fact. It seems like "Gravita Axis" might not be a
standard term in physics, astronomy, or other scientific disciplines.
However, I can break down related concepts involving gravity and axes,
which might be what the compiler is trying to show off as the only reason.
Gravity
Gravity is the force that attracts two bodies towards each other, commonly
associated with the mass of objects. It governs the motion of planets,
stars, galaxies, and even light. Key principles include:
Newton’s Law of Universal Gravitation: States that every point mass
attracts every other point mass with a force that is directly proportional
to the product of their masses and inversely proportional to the square of
the distance between them.
General Relativity: Proposed by Einstein, it describes gravity not as a
force but as a curvature of spacetime caused by mass. Objects follow the
paths determined by this curvature.
Axis
An axis in scientific terms usually refers to an imaginary line about which
a body rotates. For example:
Rotational Axis: The line around which an object rotates. Earth’s
rotational axis is tilted relative to its orbit around the Sun, which
contributes to seasonal changes.
Gravitational Axis: While not a formal term, this could refer to the axis
of rotation in a gravitational field, affecting how objects behave under
gravity.
Possible Contexts for "Gravita Axis"
Astrophysics: It might refer to the orientation or alignment of celestial
bodies in a gravitational field.
Engineering or Robotics: Could refer to a mechanism designed to respond to
gravitational forces, perhaps in terms of balance or movement.
Game Design or *Virtual Environments**:* It could describe a system
managing gravity and movement dynamics. (betyter than trees ther are so
many, why even our residences stay put; water dos not splaytter; we do not
fall etcc.
Conceptual Framework: Might be a term coined in a specific study or project
that addresses how gravity affects motion along an axis.
2 Trees tend to grow straight due to a combination of factors related
to gravity, light, and the structural properties of the trees themselves.
Here’s a breakdown of why trees grow straight both on flat land and on
mountain slopes:
1. Gravity (is also areason out of so many rest KR )
Gravitational Pull: Trees are influenced by gravity, which pulls them
downward. This force affects how they distribute their growth. The
orientation of the trunk is typically vertical, as this helps maximize the
tree’s stability and support.
2. Phototropism
Light Seeking: Trees exhibit phototropism, which is the growth response to
light. Trees grow towards light sources (usually the sun). This tendency
encourages straight growth, as the tree’s upper parts will lean towards the
light, but the overall growth maintains a straight trunk.
3. Thigmomorphogenesis
Response to Mechanical Stress: When trees are exposed to wind or other
mechanical stresses, they can adapt their growth patterns. Trees on slopes
may develop a straight trunk as a response to the stresses they encounter,
which helps them stay upright.
4. Root Structure
Stability: The root system of a tree helps anchor it into the ground,
providing stability. A deep and well-anchored root system is critical for
trees growing on slopes, allowing them to maintain a vertical orientation
despite the incline.
5. Soil and Water Access
Nutrient Access: Trees require access to nutrients and water, which can
influence their growth patterns. Straight growth ensures that they can
effectively access resources in the soil, even on slopes.
6. Genetic Factors
Species Characteristics: Different tree species have evolved to have
specific growth patterns. Many species naturally grow with a straight *trunk
as part of their genetic makeup*, allowing them to maximize light capture
and stability.
7. Competition
Crowding: In dense forests, trees often grow straight to compete for light.
A straight, tall trunk helps them rise above neighboring vegetation,
improving their chances of survival.
In summary, trees grow straight on Earth and mountain slopes due to gravity,
light orientation, root stability, mechanical stress responses, and
species-specific growth patterns. This straight growth maximizes their
ability to thrive in their environments. {KR IS IT THRASH?)

Q2 Why does a mirror reverse thing horizontally but not vertically?
KR I think same Q and A and there was no one pointing out it
because………should I say the reason I think we did study this in school and a
pofessor hgad to answer.
2 Mirror left and right is a simple eflection we learnt when we did not
know much about Physics.
The principles of mirror images, especially in the context of left-right
reversal, can be understood through basic concepts of reflection and
perception:
simple jargons are (not explained by the compiler)
Reflection: When light rays hit a mirror, they bounce off at the same angle
they arrive. This property is known as the law of reflection, where the
angle of incidence equals the angle of reflection.
Symmetry: A mirror creates a symmetrical image. What is on the left side of
your body appears on the right side of the mirror image, (not in the
mirror, as written by the compiler) and vice versa.
Left-Right Reversal: This phenomenon occurs because mirrors reflect images
horizontally. When you raise your right hand, the mirror image not the
mirror) shows a hand that appears to be on the left. It’s important to note
that mirrors don’t actually switch left and right; they reverse the front
and back.
Orientation: The reversal is about the perspective from which we view the
image. Our brains interpret the mirror image as a flipped version of
ourselves, which can create confusion about left and right.
Practical Examples: This principle can be seen in everyday scenarios, like
reading text in a mirror, where letters appear reversed. The left-to-right
confusion is due to our perception rather than a physical change in the
letters.
Understanding these principles helps clarify why mirrors behave the way
they do and how we perceive mirrored images.

Q3 What type of fires cannot be put out with water?
KR 3rd time.
2 Again only one (2 subdivisions) factors are mentiond while there are
9 factors minimum including the two. Water is generally effective at
extinguishing fires, but there are several reasons why it might not be able
to put out certain types of fires:
1 Flammable Liquids: Fires involving flammable liquids (like oil or
gasoline) can spread when water is applied, as water can cause these
liquids to float and spread the fire.
2 Electrical Fires: Using water on electrical fires can pose a serious risk
of electrocution. Water conducts electricity, which can lead to further
injury or spread of the fire.
3 Chemical Fires: Certain chemicals react violently with water, creating
additional hazards. For example, metal fires (like sodium or magnesium) can
ignite and explode when water is introduced. (compiler speaks only about
this)
4 Insufficient Quantity: If the volume of water is not enough to cool the
burning material below its ignition temperature, the fire may continue to
burn.
5 High Heat: In cases of very high heat, such as in some industrial fires,
water can evaporate too quickly to effectively cool the fire.
6 Obstructed Access: Sometimes, the fire may be in a location that is
difficult to reach with water, making it challenging to extinguish.
7 Fire Load: In situations with a high fuel load or heavy combustible
materials, water may not be sufficient to combat the intensity of the fire.
8 Fire Size: Large fires may overwhelm the capacity of water available,
making it hard to contain or extinguish.
9 Wind: Wind can spread flames and embers, complicating efforts to control
the fire with water.
In these situations, specialized fire suppression agents or methods may be
required to effectively combat the blaze. (KR: ARE THEY TRASH?)

Q4 Why have scientists not yet found a method to convert sea water
into drinking water?
KR: We have been doing that for many decades. Obviously, you are not
informed properly and that is why you asked this question. And repeatedly
I suggest that you try to learn more about each of them. {KR THIS IS ONLY
COMPILER ANSWER BUT HAD I WRITTEN IT IT WOULD BE A THRASH; WHEN HE WRITES
IT IS ALSO THEN A TRASH.
2 Modern salination plants, commonly known as desalination plants, are
facilities designed to convert seawater into freshwater, addressing water
scarcity issues in various regions. Their primary functions include:
Place Desalination plants are typically located in coastal areas
where seawater is readily available. Common locations include:
Middle Eastern countries (e.g., Saudi Arabia, UAE): These regions rely
heavily on desalination due to limited freshwater sources.
Southern California: To meet the demands of a growing population in a
semi-arid climate.
Australia: Particularly in areas prone to drought.
Function
The main functions of a modern desalination plant include:
Water Supply: Provides a reliable source of drinking water, especially in
arid or water-scarce regions.
Agricultural Support: Supplies freshwater for irrigation, helping to
sustain agriculture in dry areas.
Industrial Use: Supplies water for industrial processes, supporting local
economies.
Environmental Benefits: Can help in managing freshwater ecosystems by
reducing over-extraction from rivers and aquifers.
Processes
Modern desalination typically employs two main technologies:
Reverse Osmosis (RO): Uses semi-permeable membranes to remove salts and
impurities from seawater.
Multi-Effect Distillation (MED): Involves heating seawater to create steam,
which is then condensed into freshwater.
Considerations
While desalination is an effective solution for water scarcity, it also
presents challenges, such as:
Energy Consumption: Desalination is energy-intensive, raising concerns
about sustainability and environmental impact.
Brine Disposal: The byproduct, brine, must be managed properly to avoid
harming marine ecosystems.
Overall, desalination plants play a crucial role in managing water
resources in areas facing freshwater shortages, helping to ensure a
sustainable water supply for communities and industries.

Q5 Can you provide an example of a scientific theory that was later
proven to be incorrect? How was it disproven and what replaced it?
Throughout the history of science, several theories have been significantly
revised or replaced as new evidence emerged. Here are a few notable
examples:
*1. Phlogiston Theory*
- *Original Theory*: In the 17th and 18th centuries, the phlogiston
theory posited that a substance called "phlogiston" was released during
combustion. It suggested that materials containing phlogiston would burn
and lose it.
- *Reversal*: The theory was eventually overturned by Antoine
Lavoisier's work on combustion, which demonstrated that combustion involves
oxygen, leading to the modern understanding of chemical reactions and the
conservation of mass.
*2. Caloric Theory*
- *Original Theory*: The caloric theory proposed that heat was a fluid
(caloric) that flowed from hotter to cooler objects. This theory suggested
that heat could not be created or destroyed.
- *Reversal*: It was replaced by the kinetic theory of heat in the 19th
century, which described heat as a form of energy related to the motion of
molecules. This transition laid the groundwork for modern thermodynamics.
*3. Luminiferous Aether*
- *Original Theory*: The concept of the luminiferous aether was believed
to be a medium through which light waves propagated. It was thought to fill
space and be essential for the transmission of electromagnetic waves.
- *Reversal*: The aether theory was discarded following experiments like
the Michelson-Morley experiment and was ultimately replaced by Einstein's
theory of relativity, which demonstrated that light does not require a
medium for propagation.
*4. Newtonian Physics*
- *Original Theory*: Isaac Newton's laws of motion and universal
gravitation were seen as the final word on physics for centuries,
accurately describing motion and gravity in most circumstances.
- *Reversal*: In the early 20th century, Einstein's theory of relativity
showed that Newtonian physics breaks down at very high speeds and in strong
gravitational fields, providing a more comprehensive understanding of
space, time, and gravity.
*5. Spontaneous Generation*
- *Original Theory*: The belief that living organisms could arise from
non-living matter spontaneously (e.g., maggots from decaying meat).
- *Reversal*: This theory was debunked through the work of scientists
like Louis Pasteur, who demonstrated that microorganisms come from other
microorganisms, leading to the germ theory of disease.
KR Galileo was the last; and I have more data but stopped at it.
Even Eimstein theory overtakes Newton as not a universal theory.

Q1 How do trees that grow on a hill or mountain know to grow
perpendicular to level ground?
A1 Sean Kernan, Writer at seanjkernan.substack.com17h
This is caused by gravita axis. The short explanation is that cells are
responding to gravity as a stimuli, which causes the tree to grow against
the press of gravity.
Trees can grow in very odd shapes when an object intervenes with it:
There’s a crooked forest in Poland. The leading theory is that the planters
intervened and bent the trees at an angle at some point.
Plants and trees are generally wired to grow up and directly against the
press of gravity. It’s also key in their battle to get sun exposure.
Q2 Why does a mirror reverse things horizontally but not vertically?
A2 John-Paul Wilson, Sep 22
It doesn’t reverse things horizontally or vertically, actually. It’s
actually the fact that it preserves these directions that confuses us.
See, left and right are relative directions, meaning they change depending
on which way you’re oriented. If I stand one way then the door to the room
may be on my left but if I turn around then the door is on my right.
What a mirror does it actually reflects things exactly back with no
horizontal switching. So if I raise my left hand, the hand in the mirror to
my left raises up. The hand raised by mirror-me is on the same side as the
hand that I raised. There’s no horizontal switching.
“But” I can hear you say “it looks like mirror-you is raising its right
hand in that case!” Yes, it does. Mirror-me is raising the hand on his
right, just as I am raising the hand on his right. You could phrase this
more absolutely if you like. Say you’re looking at the bathroom mirror and
the bathroom has a toilet on one side and a door on the other side. In this
case you and mirror-you and both raising the hand nearest to the toilet, or
both of you are raising your hand nearest to the door. The mirror can never
reverse right and left and have you raise the hand nearest the toilet while
mirror-you raises the hand nearest the door.
It’s similar with text. If there was text on my shirt, it will actually be
reflected absolutely without being reversed at all. So the part of the text
on my left will also be on my left in the mirror. But the text on my shirt
was oriented for a reader who is looking at it from in front of me, so the
part of the text on my left is the end of the text, not the beginning. In
the mirror, this looks to me like the text is reversed but really the text
was simply not arranged to be read left-to-right from my own perspective.
There’s nothing magical about this: if I simply look down at my own shirt I
can see that it’s reversed left-to-right too (and upside down of course). It’s
not oriented for me to read, but for an onlooker. If I want my shirt to
read correctly for me, I have to take it off, and then turn around to face
it, thus reversing it right-to-left.
It’s actually the lack of reversing right and left in mirrors that seems
weird. We think of the mirror version of us being the same as if there were
two of us and the other one turned to face us. In that situation, if you
asked both of you to raise your left hand, you’d raise hands on opposite
sides, because the two of you have reversed frames of reference for what is
right and what is left! But if you framed the instructions in absolute
terms, telling each to raise the hand closest to the door, then the two of
you would suddenly behave like the mirror again, both raising the hand on
the same side of the room.
If there were two of facing each other, you could also read each other’s
shirts normally. Unlike with a mirror, the shirts are oriented for readers
looking from the front. But if each of you looked down at your own shirt
again, you’d see the text is still backwards, because they’re not oriented
for that perspective.
There’s simply no reversing of left and right in a mirror, and that’s what
our brains have trouble understanding.
Q3 What type of fires cannot be put out with water?
A3 Franklin Veaux, Lives in Portland, ORAug 4
Metal fires and fires involving chemicals that are more reactive than oxygen
(*ahem* fluorine *ahem*).
Water isn’t magic. It’s basically hydrogen ash. It’s what’s left over when
you burn hydrogen with oxygen. It’s a good fire suppressant because we
normally think of it as entirely burned already, so there’s nothing left to
burn.
But here’s the thing:
fluorine is such a powerful oxidizer, it out-oxidizes oxygen. Fluorine will
oxidize other oxidizers, like, oh, chlorine. If ever there was proof of
God’s indifference to creation, fluorine is it.
Fluorine by itself will burn water to produce oxygen and hydrogen fluoride.
Given half a chance, fluorine will burn chlorine, and as volatile as
fluorine is by itself, chlorine trifluoride makes fluorine drop its mask of
a kind and gentle nature, and show you what it really is.
With enough incentive, fluorine will burn oxygen, producing the evocatively
named “FOOF” that is so gleefully, exuberantly reactive as far as I know,
nobody has the faintest idea what its reaction kinetics even are.
Fluorine will burn sand. Chlorine trifluoride will burn wet sand and the
experimenter who mixed them. FOOF will burn cryogenically cooled wet sand
in a noble gas atmosphere.
Q4 Why have scientists not yet found a method to convert sea water
into drinking water?
A4 Venkateswara Swamy Swarna,I understand science and am happy to
share that. Sat
Nature has done that for millions of years and we have understood the
process quite well. We have replicated that process and successfully
produced drinking water from sea water.
We have been doing that for many decades. Obviously you are not informed
properly and that is why you asked this question.
There are many desalination plants working to convert sea water into
drinking water.
There are three main processes - ion exchange process, distillation and
reverse osmosis.
I suggest that you try to learn more about each of them.
Q5 Can you provide an example of a scientific theory that was later
proven to be incorrect? How was it disproven and what replaced it?
A5 Anthony Hughes, Former And still Retired Software Developer Sep 1
One example is the theory that the Earth orbits the Sun in a perfect circle.
They were a lot of advocates for the Earth orbiting the Sun Theory but
their problem was that the mathematics didn't work out. Using that theory
would provide incorrect answers as to where Mars would be in the sky and so
forth. So the theory was disproven pretty much from the very beginning.
Galileo was one of the obstinate people who refused to recognize this. The
theory that replaced it was the principal that the Earth still orbits the
Sun, but it it's orbit it's not a circle but an ellipse. Johannes Kepler
developed this Theory using some data that was more accurate than the
usual, collected by the observational astronomer Tyco Brahe.
The basic reason for having a theory about this at all was that astrology
was a very popular subject in Europe at that time and it was critically
important to astrology to have correct predictions of where the sun moon
and planets would be at any point in time. Since Kepler's Theory provided
more accurate answers to those questions, it was soon adopted as the
astronomical standard. Galileo's Theory basically died and was forgotten.
