• Sound is a mechanical wave that is an oscillation of pressure
  transmitted through a solid, liquid, or gas, composed of frequencies.
•  Sound can’t travel through a vacuum (an area empty of matter).
• The scientific study of sound waves is known as acoustics.
• The sound of thunder is produced by rapidly heated air surrounding lightning which expands faster than the speed of sound.
• The loudest natural sounds ever made on Earth are probably gigantic volcanic eruptions , such as the explosions of the island of Krakatoa.
• Some of the loudest sounds produced by our own invention are the
  noise of space rockets blasting from the launch pad. The biggest were
  the Saturn V rockets that launched the USA’s Apollo moon missions of
  1968-72. They had their greatest success when Apollo 11 landed on the
  Moon – an airless and therefore completely silent place – on 20 July
  1969. Once a space rocket had taken off and entered the vaccum of space,
  it became totally silent.
• One musical piece has no sound at all. It is called 4 minutes 33
  seconds. It was ‘ written ‘ by the American composer John Cage in 1954. A
  pianist sits at the piano and plays nothing for exactly 4 minutes and
  33 seconds. The content of the composition is meant to be perceived as
  the sounds of the environment that the listeners hear while it is
  performed, rather than merely as four minutes and thirty three seconds
  of silence.
• Middle C , with a frequency of 256 Hertz,is near the top of the
  singing range of a typical adult male voice. It is also near the lower
  end of the singing range of an adult female voice.
• In the deep ocean . the sperm whale uses sound to stun or kill its
  prey. Its sends out giant grunts, immensely powerful bursts of sound
  that can disable nearby fish, squid and other victims.
• Huge cathedrals, with their hard walls and floors of stone, glass
  and wood, are amazing places for acoustics. Almost any sound seems loud
  and long, a sit echoes and reverberates through the surfaces. This is
  why church singing sounds so special.
• In the recording studio any
  stray sound is a nuisance. So the walls, ceilings and floors are covered
  with sound-absorbing substances, such as wavy-surfaced tiles and thick
  carpets. There is a continuing search for ‘acoustically dead’ materials
  that absorb all sounds.

1. You’re now breathing manually.
2. You’re now aware of the facts your clothes are touching your skin and you can feel it!
3. You’re now aware that every time you swallow you hear a little crackle in your ears.
4. You’re now aware your nose is constantly in your peripheral vision.
5. You are now aware of the fact your tongue is unable to find a comfortable place in your mouth.

Myth #1 – Introverts don’t like to talk.
This is not true. Introverts just don’t talk unless they have something
to say. They hate small talk. Get an introvert talking about something
they are interested in, and they won’t shut up for days.

Myth #2 – Introverts are shy.
Shyness has nothing to do with
being an Introvert. Introverts are not necessarily afraid of people.
What they need is a reason to interact. They don’t interact for the
sake of interacting. If you want to talk to an Introvert, just start
talking. Don’t worry about being polite.

Myth #3 – Introverts are rude.
Introverts often don’t see a reason for beating around the bush with
social pleasantries. They want everyone to just be real and honest.
Unfortunately, this is not acceptable in most settings, so Introverts can feel a lot of pressure to fit in, which they find exhausting.

Myth #4 – Introverts don’t like people.
On the contrary, Introverts intensely value the few friends they have.
They can count their close friends on one hand. If you are lucky enough
for an introvert to consider you a friend, you probably have a loyal
ally for life. Once you have earned their respect as being a person of substance, you’re in.

Myth #5 – Introverts don’t like to go out in public.
Nonsense. Introverts just don’t like to go out in public FOR AS LONG.
They also like to avoid the complications that are involved in public
activities. They take in data and experiences very quickly, and as a
result, don’t need to be there for long to “get it.” They’re ready to
go home, recharge, and process it all. In fact, recharging is
absolutely crucial for Introverts.

Myth #6 – Introverts always want to be alone.
Introverts are perfectly comfortable with their own thoughts. They
think a lot. They daydream. They like to have problems to work on,
puzzles to solve. But they can also get incredibly lonely if they don’t
have anyone to share their discoveries with. They crave an authentic and sincere connection with ONE PERSON at a time.

Myth #7 – Introverts are weird.
Introverts are often individualists. They don’t follow the crowd.
They’d prefer to be valued for their novel ways of living. They think
for themselves and because of that, they often challenge the norm. They
don’t make most decisions based on what is popular or trendy.

Myth #8 – Introverts are aloof nerds.
Introverts are people who primarily look inward, paying close attention
to their thoughts and emotions. It’s not that they are incapable of
paying attention to what is going on around them, it’s just that their
inner world is much more stimulating and rewarding to them.

Myth #9 – Introverts don’t know how to relax and have fun.
Introverts typically relax at home or in nature, not in busy public
places. Introverts are not thrill seekers and adrenaline junkies. If
there is too much talking and noise going on, they shut down.
Their brains are too sensitive to the neurotransmitter called
Dopamine. Introverts and Extroverts have different dominant
neuro-pathways. Just look it up.

Myth #10 – Introverts can fix themselves and become Extroverts.
Introverts cannot “fix themselves” and deserve respect for their
natural temperament and contributions to the human race. In fact, one
study (Silverman, 1986) showed that the percentage of Introverts
increases with IQ.

1. My life is likely to last 10 to 15 years. Any separation from you will be painful: remember that before you get me.
2. Give me time to understand what you want of me.
3. Place your trust in me- it is crucial to my well being.
4. Do not be angry at me for long, and do not lock me up as punishment.
5. You have your work, your entertainment,and your friends. I only have you.
6. Talk to me sometimes. Even if I don’t understands your words, I understand your voice when it is speaking to me.
7. Be aware that how ever you treat me, I will never forget.
8. Remember before you hit me that I have teeth that could easily hurt you, but I choose not to bite you because I love you.
9. Before you scold me for being uncooperative,obstinate,or lazy, ask
yourself if something might be bothering me. Perhaps I might not be
getting the right food, or I have been out too long, or my heart is
getting to old and weak.
10. Take care of me when I get old; you too
will grow old. Go with me on difficult journeys. Never say: “I cannot
bear to watch” or “Let it happen in my absence.” Everything is easier
for me if you are there, even my death.
