Q1 Are there any harmful radiations emitted by electric lines?
If yes, what are they called?
KR: Good information from Ganesh Subramaniam, Amateur Radio Operator,
Amateur Astronomer.
However, it is as if telling every one that all energies are dangerous. No
sir. First radiation emission is explained as,” Emission of radiation is
the process by which energy is released from matter in the form of waves or
particles: Radiation can be emitted when atoms and molecules absorb energy
and jump to a higher energy state, and then release that energy to return
to a lower energy state. This process is known as an emission spectrum.
Types of radiation
Radiation can be non-ionizing or ionizing. Non-ionizing radiation includes
radio waves, microwaves, and visible light. Ionizing radiation can knock
electrons out of atoms, and can be emitted by radioactive elements, x-ray
machines, and cosmic particles.
Health effects
*Ionizing radiation* can damage tissue and DNA in genes, and can pose a
health risk. For example, gamma rays can pass through the human body and
damage tissue and DNA. Beta particles can penetrate the skin and cause
damage, and are more damaging if inhaled or swallowed.
Environmental effects
Radioactive emissions can have different effects on ecosystems. For
example, the Chernobyl nuclear power plant accident in 1994 had relatively
mild effects on mammal populations, but had a more significant impact on
bird populations
Q2 Did Einstein invent the theory of relativity or was it
discovered by someone else before him? If so, why is he not credited for it?
[A2 John Lawrence,B.S. in Physics (college major), Massachusetts
Institute of Technology (Graduated 1970)SunEinstein’s Special Theory of
Relativity is just Galileo’s Theory of relativity (Postulate 1), and
(Postulate 2) that the speed of light from any source, as measured by any
observer doesn’t depend on the motion of either the source or the observer
(not his exact words but his exact meaning). That’s his theory - Galileo &
c. Period. Hard stop.Everything else are consequences of Galileo & c -
Lorentz transforms, E=mc^2, length, time, simultaneity, and, inertia being
frame dependent, etc. They’re all logically inescapable from Galileo &
c.Lorentz also proposed a theory of relativity. In the abbreviate form I
used for Einstein’s Theory, Lorentz’s theory would have been- Galileo &
Aether.So, we have Galileo & c and Galileo & Aether. Those are different
theories. They are completely incompatible; if one is true, the other can’t
be true. Just because they happen to imply some of the same consequences
(notably Michelson & Morley’s null result) doesn’t make them the same
theory. Before Einstein nobody had said that the measured value of c is
invariant to changes in frame of reference. If the Special Theory is to be
shared it should be with Einstein and Galileo.]
KR It is a misleading reply which no well read would accept it as
correct.
A Parallel scientist who went through the process of relativity
exact were only these scientists:
Many scientists contributed to the development of the theory of relativity:
Albert Einstein Proposed the theory of special relativity and later
applied it to the universe as a whole, initiating relativistic cosmology
1Henri Poincaré A French mathematician who critiqued classical
mechanics before Einstein 1900
2 Ernst Mach An Austrian physicist who critiqued classical
mechanics before Einstein
3 Marcel Grossmann A mathematician who collaborated with Einstein
to publish the Einstein field equations in 1913
4 Karl Schwarzschild An astrophysicist who found the first
non-trivial exact solution to the Einstein field equations in 1916
5 Albert A. Michelson A contributor to the history of
special relativity
6 Hendrik Lorentz A contributor to the history of special
relativity
7 Max Planck A contributor to the work that followed Einstein's
theory of special relativity
8 Hermann Minkowski A contributor to the work that followed
Einstein's theory of special relativity
Plank theory was also relatively applied. In physics, the
relativity of simultaneity is the concept that distant simultaneity –
whether two spatially separated events occur at the same time – is not
absolute, but depends on the observer's reference frame. This possibility
was raised by mathematician Henri Poincaré in 1900, and thereafter became a
central idea in the special theory of relativity.According to the special
theory of relativity introduced by Albert Einstein, it is impossible to say
in an absolute sense that two distinct events occur at the same time if
those events are separated in space. If one reference frame assigns
precisely the same time to two events that are at different points in
space, a reference frame that is moving relative to the first will
generally assign different times to the two events (the only exception
being when motion is exactly perpendicular to the line connecting the
locations of both events). For example, a car crash in London and another
in New York that appear to happen at the same time to an observer on Earth
will appear to have occurred at slightly different times to an observer on
an airplane flying between London and New York. Furthermore, if the two
events cannot be causally connected, depending on the state of motion, the
crash in London may appear to occur first in a given frame, and the New
York crash may appear to occur first in another. However, if the events can
be causally connected, precedence order is preserved in all frames of
reference.
WHEWRE Galileo cuts in here wrt einstein theory? NOWHERE. But yes
Einstein said: ‘Albert Einstein called Galileo Galilei the "father of
modern physics and in fact of the whole of modern natural science".
Einstein was inspired by Galileo's support for empirical experimentation
and observation, and Galileo's contributions to observational astronomy and
the scientific revolution. MAY BE JAUNDICED BRAIN MAY NOT READ IN BROAD
STYLE BUT TRIES TO KICK AT OTJHERS AS AN IGNORANT?
-----------------------------------------------
Q3 Is there a scientific explanation on why someone would be
smiling wide when they are dead?
KR: Scientific explanation? Stories of good thoughts and
peaceful deaths are welcome. However, where the dying is known and the
dying is aware of the imminent, if remembering the Govindan well, a smile
shall prevail.
'Peaceful' refers to the dying person having finished all business and made
peace with others before his/her death and implies being at peace with
his/her own death. It further refers to the manner of dying: not by
violence, an accident or a fearsome disease, not by foul means and without
much pain.
The Vedic scriptures emphasize the impermanence of life and the ephemeral
nature of the physical body. The shloka “जातस्य हि ध्रुवो मृत्युर्ध्रुवं
जन्म मृतस्य च। तस्माद अपरिहार्ये ऽर्थे न त्वं शोचितुम् अर्हसि॥”
(Mahabharata – Bhishma Parva 2.27) reminds us that death is certain for the
one who is born and that rebirth is inevitable for the one who dies. It
urges individuals not to grieve over the natural cycle of life and death.
“anāyāse maraṇa, jīvana dainya vine kṛṣṇa sevile se haya, nahe vidyā-dhane
|| 137 ||“anayase marana, jivana dainya vine krsna sevile se haya, nahe
vidya-dhane (137):(137) “If one wants to live without poverty and die
peacefully, then he should serve GOD. Education and wealth will not help.
Joy and wisdom mark the deaths of these heroes; while suffering and
surrender mark the deaths by suicide. Don’t the suicides choose their
deaths? Apparently yes, but really no. Suicides don’t actually “choose”
death. They turn to death only when they feel they have no choices left. To
them, death appears as the only exit-route to escape from the burdens they
can no longer bear. Unfortunately, death is no escape at all, it’s only an
additional burden if it comes about through suicide. Suicide is an
admission of defeat. Suicides don’t choose their deaths. It is death that
chooses them when they are worn-out and defeated. Suicide is no act of
bravery. It’s not a death by choice. It’s a death by a vague and
self-induced sense of compulsion. We may not be cowards, but we may not
also get the opportunity to choose the external circumstances leading to
death. Such opportunities come to very few. But that shouldn’t matter
really. Our choices in the external world are limited. In the internal
world, however, we have all the possible choices. Inside, we are our own
masters. Our word reigns supreme within. It is in the inner world,
therefore, that we must choose our death before death chooses us in the
external world. The only way to neutralize the terror of death is to “die”
before dying., “Be in the world like a traveller, or like a passer on, and
reckon yourself as of the dead. Japanese Zen Master, taught: “If you are
really desirous of mastering Zen, it is necessary for you to once give up
your life and to plunge right into the pit of death.” So smile is where
heroes die. KR IRS 161224
Q4 Is there a muscle in the human anatomy that serves no purpose
but still exists?
KR Reply is information according to the Jaundiced brain.
{compiler comments: My note- If you read fully with concentration, you will
find these are informative. But for persons who are having jaundice, these
QA may be useless.} I feel, mere information is passing clouds without
rain; I opine as read a few Indian and foreign texts, that in the creation,
there is no waste or useless product at all, in the design of the
structures of space or body.
Some human body parts have become useless over the past few million years.
These include wisdom teeth, the tail bone, and the muscle fibers that
produce goose bumps. Take a look at nine body parts that remained in the
human body despite having no function for millions of years Many years ago,
the appendix may have helped people digest plants that were rich in
cellulose, according to a 2016 study in the journal Clinical and
experimental immunology. While plant-eating vertebrates still rely on their
appendix to help process plants, the organ is not necessarily an essential
part of the human digestive system. Though some research suggests it may
act as storage for good bacteria.
If you rest the back of your wrist on a table and connect your thumb to
your Pinky, you may see a band of muscle pop up on your wrist. That is a
vestigial muscle called the palmaris longus. Amir said this muscle is there
because it helped our ancestors climb trees. According to the Encyclopaedia
Britannica, the muscle likely also helped early humans with their grip,
possibly while hanging. But we started walking on two feet about 3.2
million years ago, eventually making the muscle more-or-less useless. "It's
been a while since it was useful," Now, however, someone's grip strength is
the same whether or not they have the muscle. "Natural selection is not a
system geared toward perfect efficiency,"
So a part helps only at a rare event or for only in a circumstances, they
do not mean they are useless. We carry our brain to death without usage
whereas siddhas exhaust their brains. So, is that a waste? The creator
envisaged every situation and time of needs even asingle individual may
require.

Q1 Are there any harmful radiations emitted by electric lines?
If yes, what are they called?
A1 Ganesh Subramaniam, Amateur Radio Operator, Amateur
AstronomerDec 10
Radiation level from household electrical wiring is very low - and not
considered dangerous to residents. However, HT lines - typically 1 KV to 11
KV, and Super Tension 22 to 33 KV, Extra High Tension 33 KV to 66 KV and so
on - radiate powerful electromagnetic fields or EMF that is hazardous to
health.
Years of studies worldwide has shown that living close to high voltage
power lines increases your risk of cancer and other health problems. These
strong, EMFs radiates from power lines interfere with your body’s natural
EMF, causing insomnia and increase in stress levels, interfering with your
immune system and even the DNA. Needless to mention, your proximity to the
HT lines increases the danger of EMFs. Here is a handy reference to the
danger at different distances from a 765 KV line
The EMF from HT power lines is “non-ionizing” radiation because of low
frequency, and is considered less harmful to humans than the
higher-frequency—or ionizing—radiation - such as nuclear radiation or radon
gas -which damages cells and DNA and causes increased chances of cancer.
Aside: Long ago, I lived within about a kilometer from a 110 KV HT line.
There were houses almost right underneath the lines - flouting government
regulations, no doubt - and so I appraised the residents there of the
dangers of EMF radiation and demonstrated it by holding a fluorescent tube
standing under the humming HT lines. Yes, we could hear the hum clearly.
The fluorescent lamp lit up as if connected to 234V AC at home! Later I
came to know a couple of families who lived in rented houses had moved, but
folks who owned houses in the area had no such option.
Q2 Did Einstein invent the theory of relativity or was it

Q3 Is there a scientific explanation on why someone would be
smiling wide when they are dead?
A3 Alice Williams,Sat
I am a nurse that works with people at their end of life.
LEARNN
I am an acute care physician, so these patients came in with an illness -
we are not a high-trauma facility - and they usually don't have much time
to process that they are at the end of life and going to die in the
hospital.
I thought the stories below were necessary to make the dying beautiful and
to dispel fear of it.
And I think that most people that do talk during that process will say they
have been visited by people that have come in before.
MOREE
The vast majority of visits my patients get are from relatives who died
many years ago.
CHECK
Family pets have visited as well as grandparents and parents.
MY BIO
When I was a baby, my mother's father committed suicide - she said he came
to visit me even.
In the dying process my patients will reach up into the sky like they are
reaching for something.
LINKKK”K”
If they are more alert I will ask "What are you reaching for" They'll call
a deceased relative by name and they always seem comforted by these visits.
Patients say "I need to go!" Most lay people confuse the "I need to go,"
with the need to use the bathroom. Most often when you take them to the
bathroom they either do not use it or tell you insistently that they did
not have to use the bathroom. Then they usually say "I told you I had to
go," trying to answer the question "where do you have to go." A nearly
universal answer is "home," which the patient almost always answers. Well,
now home could be their house where they come from, but again, "your home
where you live?" And sometimes they'll say home, not that home. Just go get
me out, "she said. This is when I say therapeutically "you can't go home
yet, let us try to make you as comfortable as possible." I then throw lots
of fluffy pillows on their backs and arms for comfort. I think my patients
are in limbo, not quite here, not quite out, and it is frustrating.
The patients calm down once things get further into the dying process.
Visitors in person and spirit are comforting, and the bodies begin to slow
down, allowing for more sleep. They awake refreshed, hungry and talkative.
These periods are called rallies.
Sleeping occurs between rallies to help with recovery. Then they are rested
for their next journey.
I have had patients reach up and smile because they told me their husband
was going home years ago.
I've been with patients whose last breath was while I and eight other
family members sang Jesus loves me.
I have been in a room where just before you died a light went on above the
bed. It was Christmas Eve, and I remember the patient by name: It will stay
with me.
Some will say, "How can someone who went to the hospital for something and
who is never going home have peace?" I think these spiritual visits bring
peace. The dying are comforted with peace. I personally believe God sends
angels to comfort us because we are scared.
I believe your brother was very comfortable and went "home," that's why he
smiled.
Q4 Is there a muscle in the human anatomy that serves no purpose
but still exists?
A4 Michael Turner, Studied Biology at University of Hull (UK)Dec
11
Potentially; we are still finding new organs and tendons (we found a new
tendon in the knee a few years ago, 2013, and a new organ, I think in the
throat in the last few years, possibly others that I don’t know about).
So it is possible we have muscles we haven’t yet identified and that have
no purpose due to them become vestigial.
The closest things I can suggest are the following:
Look at muscles we steal from for tendon grafts, and also the muscles
around the human ear, and I guess the hair follicles.
Number 1 - Auricular Muscles
These are the small muscles around your ears. In many animals, they’re used
to swivel the ears toward sounds, which is incredibly useful if you’re
hunting or avoiding predators. For humans, though, they don’t do much. *Some
people can wiggle their ears thanks to these muscles, but for most, they’re
just sitting there doing absolutely nothing*. If anything, they’re a party
trick waiting to happen — if you’re one of the lucky few who can move them.
MY NOTE- One of my late elder brother’s son can wiggle his ears
2. Arrector Pili Muscles
These tiny muscles are attached to your hair follicles and are responsible
for causing goose bumps. In our furrier ancestors, this would have been
useful for trapping heat or making them look bigger to scare off predators.
For us? Goosebumps might be good for a horror movie moment, but they don’t
really serve much purpose anymore unless you’re trying to terrify someone
with your arm hair.
3. Palmasris Longus
This is a slender muscle in the forearm that about 80–90% of people have.
It helps a little with wrist flexion and tenses the palmar aponeurosis (a
sheet of connective tissue in the palm). The thing is, if you don’t have
it, you’re not at a disadvantage—studies show no meaningful difference in
grip strength. It’s so underwhelming that surgeons regularly harvest its
tendon for grafts, and people don’t miss it. Basically, it’s the anatomical
equivalent of a spare part.
4. Plantaris Muscle
Found in the leg, this muscle has such a minimal role in knee flexion that
it’s often removed for tendon grafts. People who lose it don’t notice any
difference, which tells you everything about its importance. It’s like the
MySpace of muscles — once thought to have potential but now irrelevant and
only remembered when someone needs to salvage something from it.
So, Are There Truly Useless Muscles?
In the strictest sense, no muscle is completely useless. Most have at least
a minor function, even if it’s vestigial. That said, some are clearly
leftovers from evolution that didn’t get the memo. And who knows? There
might be muscles or structures we haven’t discovered yet, quietly existing
without a purpose. Evolution doesn’t always clean up after itself—it often
just leaves behind parts it doesn’t need anymore.Additional information
A Fun Fact About Evolutionary Leftovers
Recent research shows humans have at least 2,650 DNA base pairs that encode
the ability to metabolize hydrogen as an energy source instead of sugar.
These genes are common in bacteria that live near volcanic sea vents, which
suggests our ancient ancestors may have lived around these extreme
environments billions of years ago.
Of course, these instructions are largely broken—like a soggy instruction
manual with torn pages and smudged ink. But they’re still buried in our
genetic code, which I think is pretty remarkable.

informative. But for person’s who are having jaundice, these QA may be
useless.*
