This includes calling friends “Mateys”, the word “Cap’n” appears before
everyone’s name, pictures are called portraits, commenting is called
“scrawling a mark”, and instead of liking something you just say “Arr!”.

You have to go into “Account” and then “Languages” and find “English (Pirate)”.

This made him 0.2 seconds younger than he would have been if he had never gone into space. To put it in another way, he traveled 0.02 seconds into the future.

Hypothetically, you travel a whole lot more in time if you traveled faster, closer to the speed of light.

Confused? Perhaps Carl Sagan can explain it better in this interesting video.

Ever see those Bugs Bunny cartoons where Bugs would paint something red
and a bull would go crazy and charge at it? Turns out that wouldn’t
work.

The Mythbusters tested this one out and found that the bulls were just
as likely to charge at white flags and blue flags as they were to charge
at red ones. The bulls also ignored a guy dressed in red who stayed motionless. Turns out that bulls just charge at whatever moves the most, regardless of color.

This makes sense, since bulls wouldn’t be able to tell if a cape or a flag was red anyway. Bulls are colorblind. Besides, in the middle of a bullfight, the bull is probably more mad about having a bunch of guys stabbing him with spears than he is about the color of the matador’s cape.

The other reason the myth may have arisen is because you don’t
often find ducks hanging around places where you commonly get echoes,
like cliffs on a beach, or large cathedrals!

• 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.
