Q1 What does the theory of continental drift state?
By Mr G Unread un verified but relied upon not as thrash:
A1 Paul Noel, BSCS in Bachelor of Science in Computer Science,
Athens State University, Athens, Alabama (Graduated 1999)Aug 5
You have to understand that there is no “unified” or “doctrine” of
continental drift.
There are a lot of explanations, some of which are very real and some are
just a stinking pile of crap. It is ill defined.
I would say that it is very clear that the major continental land masses
were connected. It is very clear that they are now at a distance from each
other. It is also quite clear that this is a process of rifting and that
the process is ongoing in locations around the earth.
It is very important for you to understand that the mechanisms have many
cute explanations but honestly the reality of these explanations is less
real than most people assume. The history of the theory is actually quite
old. As soon as maps of the Atlantic Ocean basin were made students
observed that North and South America could be nominally fit into Europe
and Africa. It is important to understand this history. Even as early as
1900 this fit was matched over by rock strata and mineral and mine deposits
were matched across.
The US Navy had to map the world’s oceans for submarine navigation issues.
What you may not know is how critical such mapping is and it is dynamic.
Here is the cost of a mistake of such mapping problems.Messed up several
billion dollars of machinery in such a mistake. This is critical.
The USA did something amazing in the 1970’s in that it freed up to the
public some of these maps and they were eye opening. What had been a
curious and not too well supported theory suddenly was clearly going on. It
took Academia nearly 20 years to get its head around this reality and to
accept it. They didn’t trust the military.
Now there was a big problem that developed. If the size of the planet is
relatively fixed and most people assume such, then you have to figure out
what happens to large sections of the crust of earth when you move around
continents. You also have to figure out a whole lot of other things.
For example one major flaw in the theory at this time has to do with the
geological matches in other ocean basins. All ocean basins have the same
matching of continental shelves as does the Atlantic Basin.
I am not proposing to you to have all the answers but it is very clear
that many of the explanations you see today are just plain wrong.
I have pointed out in the past that the species of the Coastal Redwood
trees in California match with minor variations in Japan and China. This
means it too spread apart. Time really isn’t important to this data. The
species and archaic fossils show that South America was connected to New
Zealand and Australia as well. This isn’t the “sub duction” model you see
explained at all.
This is but one of many difficulties this cobbled together theory has. Now
unlike some other theories this one isn’t all wrong or all right. It is
just a problem of figuring out the details here. I am not proposing myself
to have all of the answers but the process does not work as explained.
But this is not a problem of the plates being wrong. We can map the plates.
The interpretations are wrong. Not by any means are all explanations wrong
either. Some are wrong.
You should see the “Theory of Plate Techtonics” as a work in progress and
actually a very young one at that. It has a lot of errors in it and there
are NOT any complete “The Theory” realities here. It is more of a pile of
explanations that some are right and some are wrong.
Modern Science and Geology in particular tends to acquire dogma that is not
right and they live past their time. In the past “Gradualism” was the
dogma. We know now that many events happen suddenly.
Right now the acceptance of “Episodic Catastrophe” is being overplayed as
well. We don’t even know where the energy comes from that drives the
system. So don’t assume that there is some theory that works.

1, 4 and 6 I have read. It is available in USA lib. The other books stated
are in my pending list. They are top 10 books that clearly focussed state
what is done with the bartholomew maps that too authentic (he has produced
our Bharatha varsha) They are not thrash and they dont brag as Mr G bragged
here,
pl explain the history and content of continental drift
The theory of continental drift is a crucial part of the broader field of
plate tectonics, and its development has been a significant milestone in
understanding Earth's geology. Here’s a concise history and overview of the
theory:
Historical Development
Early Observations (16th–19th Century):
1596: Abraham Ortelius, a Flemish cartographer, first suggested that
the *continents
might have once been joined together*. He noted that the coastlines of
Africa and South America seemed to fit together like puzzle pieces.
19th Century: Several scientists, including Antonio Snider-Pellegrini, began
to speculate about the continents fitting together in a supercontinent,
which they named "Pangaea." (What we called it as Bharatha varsha s
sanskrit was Pangea to the west where a few corrections were being added
later; and literally Ramanujar drew a picture about which I wrote some time
back fits squarely; of course I wrote a long ago about et al. But learned
did not read any of them as a thrash lover. KR)
Alfred Wegener's Theory (1912):
1912: Alfred Wegener, a German meteorologist and geophysicist, formally
proposed the theory of continental drift. In his seminal work, "The Origin
of Continents and Oceans", Wegener argued that continents had once been
joined together in a single supercontinent called "Pangaea." He suggested
that Pangaea gradually broke apart, and its fragments drifted to their
current positions.
Evidence Presented:
Fit of the Continents: The jigsaw-like fit of the coastlines of continents
such as South America and Africa.
Fossil Evidence: Similar fossils of plants and animals, like the extinct
reptile Mesosaurus, found on continents now widely separated by oceans.
Geological Evidence: Matching geological formations and rock types on
continents that are now distant.
Paleoclimatic Evidence: Evidence of past climates, such as glacial deposits
in now-tropical regions and coal deposits in now-temperate regions,
indicating that continents had different positions in the past.
Initial Reception and Criticism:
Wegener's ideas faced skepticism because he could not provide a convincing
mechanism for how continents could drift through the Earth's solid crust.
His hypothesis was largely dismissed by many geologists at the time.
Development of Plate Tectonics (1960s):
1960s: The theory of plate tectonics emerged, providing the mechanism
Wegener lacked. Key contributions included:
Seafloor Spreading: Proposed by Harry Hess and Robert Dietz, this theory
explains that new oceanic crust is created at mid-ocean ridges and then
slowly moves away from the ridges, pushing the continents with it.
Confirmation of Continental Drift: The discovery of magnetic striping on
the ocean floor provided evidence for seafloor spreading and confirmed that
continents drift as a result of plate movements.
Modern Understanding:
Plate Tectonics: Today, the theory of plate tectonics integrates
continental drift with the understanding of the Earth's lithosphere (the
rigid outer layer of the Earth) being divided into several large and small
tectonic plates. These plates float on the semi-fluid asthenosphere beneath
them and move due to forces such as mantle convection, slab pull, and ridge
push.
Continents and Plate Boundaries: Continents are part of tectonic plates
that interact at their boundaries, leading to geological phenomena such as
earthquakes, volcanic activity, and mountain building.
Content of the Theory
Continental Drift:
The hypothesis that continents have moved over geological time from a
single supercontinent to their current positions.
Plate Tectonics:
The modern theory that explains how the Earth's lithosphere is divided into
tectonic plates that float on the semi-fluid asthenosphere and interact at
their boundaries.
Evidence Supporting the Theory:
Fit of Continents: The way continents fit together.
Fossil Distribution: The presence of identical fossils on widely separated
continents.
Geological Formations: Continuity of geological formations across
continents.
Paleoclimatic Indicators: Evidence of past climates that suggest continents
were once located in different positions.
Mechanisms:
Seafloor Spreading: The process by which new oceanic crust forms at
mid-ocean ridges and spreads outward.
Subduction: The process by which one tectonic plate is forced beneath
another, leading to the recycling of crustal material.
Continental drift and plate tectonics revolutionized our understanding of
Earth's dynamic nature, providing explanations for the distribution of
earthquakes, volcanic activity, and the formation of mountain ranges.

Q2 What's the smelliest thing you've ever encountered?
KR: Pig farms I have crossed in the USA; it is not that pigs give out
smell since under the USA law, that fellow would have been in Gallows. The
top smells are:
The "worst" smell can be highly subjective, but several odors are often
cited as particularly unpleasant. Here are some of the most notorious ones:
I Hydrogen Sulfide (H₂S): ( In the college I had run out of the lab)
Often described as smelling like rotten eggs, hydrogen sulfide is a
byproduct of decay and is found in sewer gas and volcanic emissions. At
high concentrations, it can be toxic.
II Dimethyl Sulfide (DMS): This compound has a strong, unpleasant odor
often compared to the smell of decaying seafood or cabbage. It is found in
some marine environments and in the processing of certain foods.
III Putrescine and Cadaverine: These are chemicals released during the
decomposition of animal flesh. They have foul odors reminiscent of rotting
meat or dead bodies.
IV Skunk Spray: Skunk spray is famous for its strong, pungent smell,
which is a mix of sulfur compounds. It's a defensive mechanism used by
skunks to ward off predators.
V Ammonia: Ammonia has a sharp, acrid smell that can be
overwhelming, often associated with stale urine or cleaning products.
VI Rotten Fish: The smell of rotting fish is due to the breakdown
of proteins and fats, producing compounds like putrescine and cadaverine.
VII Durian Fruit: Known as the "king of fruits" in Southeast Asia,
durian is infamous for its strong, pungent odor, which some people find
unpleasantly overpowering. The smell has been compared to rotten onions or
turpentine. (Have you smelled it?) (Go to Korean shops in California)
VIII Sewer Gas: A mix of various gases including hydrogen sulfide
and methane, sewer gas can have a particularly foul smell.
IX Cheese made from fermented fish (Surströmming): Surströmming, a
traditional Swedish dish of fermented herring, is known for its intensely
pungent odor, which can be so strong that it is banned on airplanes.
These smells are often associated with substances that signal decay,
toxicity, or strong chemical reactions, making them particularly unpleasant
to most people.

Q3 How many Nobel Prizes in Physics should Nikola Tesla have been
awarded? Why was he shunned by the Nobel Prize committee?
BY learned MR G A3 Jim Mowreader, Printing Expert (1994–present)
May 27 None. The only thing Tesla really invented that lots of people
still use today was radio control.
Nikola Tesla was a prolific inventor and visionary whose work laid the
foundation for many modern technologies. Here’s a list of some of his most
notable inventions and contributions:
1. Alternating Current (AC) System (NOT AC)

electricity, and is used in various scientific experiments and
demonstrations.
3. Induction Motor (from direct to induction and today's stove is an
impact from it)
Description: Tesla's induction motor operates on alternating current and
utilizes electromagnetic induction to generate motion. It’s more efficient
than previous DC motors.
Impact: This type of motor is widely used in various appliances and
industrial machinery.
4. Transformer (ONLY THAT DRAWING DESIGN THAT WAS CONSIDERED NEW)
Description: Tesla’s design of the transformer is essential for stepping up
or stepping down voltage levels in AC power systems.
Impact: Transformers are crucial in the electrical distribution network,
allowing for the efficient transmission of electricity over long distances.
5. Wireless Transmission of Energy (HE DID NOT SUCCEED; BUT THE THEORY IS
BASE FOR TODAYS WIRELESS)
Description: Tesla experimented with transmitting electricity wirelessly
using resonant inductive coupling. His experiments included the famous
Wardenclyffe Tower.
Impact: Though not fully realized in his time, his work laid the groundwork
for modern wireless communication and energy transmission technologies.
6. Radio Waves and Radio Technology
Description: Tesla made significant contributions to the development of
radio waves and the technology of radio transmission. He demonstrated
wireless transmission of signals before Guglielmo Marconi.
Impact: Tesla's work in radio was fundamental to the development of modern
communication systems.
7. Tesla Turbine (ALTERNATIVE DESIGN WAS EVOLVED ONLY FROM HIS DRAWING
WHERE 99% DRAWINGS ADOPTED WAS ONLY THAT OF TESLA)
Description: The Tesla turbine is a bladeless turbine that uses the
boundary layer effect to achieve high efficiency. It consists of a series
of smooth, closely spaced disks.
Impact: Although not widely adopted, it has inspired research into
alternative turbine designs and methods of fluid dynamics.
8. Neon Lighting (YES HE DID IT BECAISE OF WHICH WORLD BLINKS EVEN IN
MIDNIGHT SEEING FROM PLANE)
Description: Tesla was instrumental in the development of neon lighting. He
demonstrated neon lights in his public lectures and patented various forms
of electrical discharge lighting.
Impact: Neon lights are still widely used for signage and decorative
lighting.
9. Remote Control (YES THE THEORY FOR ONLY BOAT OF HIS HELPED TODAY
WITHOUT PATENT ACK BASED ON TESLA)
Description: Tesla demonstrated the first remote-controlled boat in 1898.
His technology used radio waves to control the boat from a distance.
Impact: This invention paved the way for the development of modern
remote-control technology used in various applications.
10. Oscillator and Seismograph {TESLA FOUND THE METHODS OF RIGHT
INTERPRETATIONS BECAUSE OF WHICH WHILE tn WEATHER CALLS SHOTS WRONGLY, USA
COULD PREDICT SNOW AT 130 PM AS RIGHT)
Description: Tesla created a mechanical oscillator that he claimed could
induce seismic effects. He also developed a seismograph for measuring
vibrations.
Impact: While the oscillator’s potential for causing earthquakes was
speculative, Tesla’s work contributed to the understanding of vibrations
and oscillations.
11. Wireless Transmission of Data
Description: Tesla explored the possibility of transmitting data wirelessly
over long distances, which was an early concept of what would become the
internet and modern wireless communication.
Impact: His ideas influenced future developments in wireless communication
and data transmission technologies.
12. Tesla’s X-ray Experiments
Description: Tesla conducted early experiments with X-rays, although he did
not fully develop this technology. His work contributed to the
understanding of electromagnetic radiation.
Impact: Tesla's experiments were part of the broader exploration of X-rays,
which became crucial in medical imaging and diagnostic technology.
Nikola Tesla's work was ahead of his time, and many of his inventions and
theories have had a lasting impact on modern science and technology. His
legacy continues to influence the fields of electrical engineering,
physics, and wireless communication.
Tesla is as a genius as G D Naidu; as GD is side stepped some do these
kinds of gopal learned abuses; Tesla books are aplenty here; pl read; and
Tesla electric car is rounding the streets of Dallas and may reach India
soon. Thannathaan kaakkin sinam kakka kaavaakkaal sogappar sol izhukkup

Q4 Why do people grow shorter with age?
KR Self G corrected own Q Thank u
Q5 Where is a person most likely to be hit by lightning?
KR OMG what a senseless Q and A senseless?
Lightning can and does strike people directly, although it is relatively
rare compared to the total number of lightning strikes. Here’s a detailed
look at how and why this can happen:
How Lightning Strikes People
Direct Strike: A direct lightning strike occurs when lightning hits a
person directly. This can happen when someone is standing in an open area,
such as a field, during a thunderstorm. The electrical current can travel
through the body, causing severe injuries or even death. (near teynampet a
young kid was charred a few years back)
Side Flash (Side Splash): This occurs when lightning strikes a nearby
object (like a tree or a building) and some of the current jumps from the
object to a person standing close by. Even though the person was not the
primary target, they can still be injured by the lightning.
Ground Current: Lightning can strike the ground, and the electrical
current can spread outwards from the strike point. If a person is standing
on or near the ground where the lightning has struck, the current can
travel through the ground and into their body, causing injuries.
Conduction: Lightning can travel through conductive materials such as
metal rods, pipes, or wiring. If a person is in contact with these
materials during a lightning strike, they can be injured by the electrical
current conducted through them.
Injury and Survival Injuries: Direct lightning strikes can cause a
range of injuries, including burns, cardiac arrest, neurological damage,
and even death. The high voltage and current can disrupt the body’s
electrical systems and cause severe damage. ( cardiac arrest is also only
one cause of death where it is remote)
Survival: Some people survive direct lightning strikes, though they often
suffer severe injuries. Survivors may experience long-term health issues,
such as chronic pain, memory loss, and other neurological effects.
Statistics and Safety Tips
Incidence: Lightning strikes are relatively rare, with thousands of strikes
occurring each year globally. However, people in open or elevated areas,
such as golfers or hikers, are at higher risk.
Safety Measures: To reduce the risk of being struck by lightning:
Seek Shelter: During a thunderstorm, seek shelter indoors or in a vehicle.
Avoid open fields, tall trees, and isolated structures.
Avoid Conductors: Stay away from metal objects and avoid touching
conductive materials.
Follow Safety Guidelines: Pay attention to weather warnings and follow
safety guidelines for lightning safety.
In summary, while lightning can indeed strike people directly, the risk is
relatively low compared to other lightning-related incidents. However, it
is crucial to follow safety precautions during thunderstorms to minimize
the risk of injury.

Q2 What's the smelliest thing you've ever encountered?
A2 Sean Kernan, Writer at seanjkernan.substack.com Jun 7
A pig farm.
I’d rather swim in raw sewage than deal with that.
The smell overtakes you before you get to them. There is just a nastiness,
a mix of sweat, their own bodily fluids which they roll in, and the smell
of pig.
They seem like very nice animals overall. But I can’t be near them.
Farming isn’t for the faint of heart.
A close second was when I was at a convenience store, and the sewage truck
was draining sewage from some breakage in the building. I had to leave
because I was worried the smell would peel the paint off my car.
Q3 How many Nobel Prizes in Physics should Nikola Tesla have been
awarded? Why was he shunned by the Nobel Prize committee?
A3 Jim Mowreader, Printing Expert (1994–present) May 27
None.
The only thing Tesla really invented that lots of people still use today
was radio control.
He didn’t invent AC - that was perfected before he was born. He didn’t
invent poly phase AC. He didn’t invent the induction coil. He didn’t invent
the transformer. He DEFINITELY didn’t invent the AC motor. He invented a
really cool device to automatically adjust the two carbons in an arc light,
but arc lighting completely died when the mercury vapour bulb was created….he
didn’t invent that either. Tesla did two things in his career: improved
quite a few things, and promoted electricity so people would see it as
something they should be using. Getting people to use electricity was a
great thing, but not a Nobel-worthy thing.
If I was going to give a Nobel to any of the electrical pioneers, it would
go to two people: Thomas Edison, who invented motion pictures, and Oliver
Shallenberger, who invented the electric meter.
I consider Shallenberger’s meter to be the most important invention of that
era - by making it possible to accurately bill customers for the
electricity they used, Shallenberger encouraged people to take the risk of
building power plants with the assurance they’d be able to repay the debts
they incurred to build them.
Q4 Why do people grow shorter with age?
A4 Bob Wilson, Jul 4
I think the terminology is wrong, if you grow, you get taller, probably
shrink would be a better term. But I get your meaning, and it's a real
thing.
Your cartilage in back bone flattens, the space between your joints
narrows. This accounts for about an inch over a life time.
If you lose more than that, you should probably let your doctor know, you
probably have something else going on.
The most common problem is osteoporosis. You lose bone mass. Which is why
it's a good idea to do some weight training before your hormones change.
My next door neighbour, who lived to be 95, told me that she had lost 3
inches, two inches after 85 years of age.
My cousin had bone cancer, and went through radiation and chemo, and when
he was fully in remission, he had lost 5 inches, he used to be taller than
his wife, and then he wasn't.
I am not doctor, so visit a doctor if you notice that you are shrinking.
2nd answer-Enosh Collins,Centre Back, M.A. English, Manchester United fan!

Vision, hearing, memory and hair are just a few things that tend to
disappear as the candles increase on our birthday cake. Unfortunately,
height can be added to this list. In fact, we can begin shrinking as early
as our 30s.
Our height is determined by the length of the leg bones, the spine, and the
skull. While the leg bones and the skull remain pretty much unchanged in
length after we reach adulthood, our spinal bones (the vertebrae) tend to
shrink. Most of us have 24 vertebrae. They're stacked on top of one another
like a roll of dimes, but (unlike the dimes) are tethered tightly to each
other by fibers and muscles, so they keep us straight.
As we age, in many of us (men as well as women) the bones start to get
thinner. Each of the vertebrae becomes a little shorter. Therefore, so do
we. With full-blown osteoporosis, people can lose several inches in height.
Men can gradually lose an inch between the ages of 30 to 70, and women can
lose about two inches.
Older adults can get shorter because the cartilage between their joints
gets worn out and osteoporosis causes the spinal column to become shorter.
Sarcopenia is characterized by a decrease in muscle mass, which leads to
weakness and frailty and also a decrease in height.
The solution:
Eating foods rich in calcium and vitamin D, such as dairy, fruits and
vegetables, can help keep your bones strong. Also, doing weight-bearing
exercises can help thwart shrinkage.
Q5 Where is a person most likely to be hit by lightning?
A5 Sean Kernan, Writer at seanjkernan.substack.com Jul 8
Flat areas with few objects elevating high above you, when it is raining,
and also lightning.
Being on the ocean in a small boat, or golf course, or in a field, are all
places where people get struck all the time.
Contrary to what is commonly said—you don’t usually get struck directly by
the lightening, with it connecting with your head or arm first. It
generally strikes something near you.
This is what it does to a tree:
If you are struck directly by the lightning, your odds of survival fall off
quite a bit more.
People usually die due to cardiac arrest. The voltage just screws up your
body too much.
But even if you do survive, you often suffer from nerve damage that takes
time to recover from. It’s no picnic. Be safe.
