How does the clock works

shared by marino5856 on 31 Oct 14 - No Cached
  • A day consists of two 12-hour periods, for a total of 24 hours. An hour consists of 60 minutes. A minute consists of 60 seconds. Seconds are subdivided on a decimal system into things like "hundredths of a second" or "millionths of a second."
    • marino5856
      marino5856 on 04 Nov 14
       
      There is 24 hours in a day because  they first divided 60 and that equals 12. So 12 plus 12 equals 24 so thats how they had 24 hours in a day.
  • hat's a pretty bizarre way to divide a day up. We divide it in half, then divide the halves by twelfths, then divide the twelfths into sixtieths, then divide by 60 again, and then convert to a decimal system for the smallest increments. It's no wonder children have trouble learning how to tell time.
  • How long is a day? It's the amount of time it takes for the Earth to rotate one time on its axis. But how long does it take the Earth to rotate? That is where things become completely arbitrary. The world has decided to standardize on the following increments:

  • Why are there 24 hours in a day? No one really knows. However, the tradition goes back a long way. Take, for example, this quote from Encyclopedia Britannica:
  • Why are there 60 minutes in an hour and 60 seconds in a minute? Again, it is unclear. It is known, however, that Egyptians once used a calendar that had 12 30-day months, giving them 360 days. This is believed to be the reason why we now divide circles into 360 degrees. Dividing 360 by 6 gives you 60, and 60 is also a base number in the Babylonian math system.
    • marino5856
      marino5856 on 04 Nov 14
       
      The Egyptians had a calendar that has 12 months so that equals 360 day in total. Also science they new that there is 360 days in a year thats why a circle is 360 degrees. The Roman people invented that so that in the clock there is not 24 hours in a clock so there is 12 am and 12pm.
  • What do a.m. and p.m. mean? These abbreviations stand for ante meridiem, before midday, and post meridiem, after midday, and they are a Roman invention. According to Daniel Boorstin in his book The Discoverers, this simple division of the day into two parts was the Romans' first increment of time within a day:

  • The average kid has a busy day. There's school, taking care of your pets, running around with friends, going to sports practice or other activities, and doing your homework. By the end of the day, your body needs a break. Sleep allows your body to rest for the next day. Everything that's alive needs sleep to survive. Even your dog or cat curls up for naps. Animals sleep for the same reason you do — to give your body a tiny vacation.

shared by Diego Hinojosa on 04 Nov 14 - No Cached
  • The planet that Voyager uncovered is a stormy, windswept world with a vivid blue hue. Its highly active atmosphere is surprising, since it receives so little sunlight to power its weather systems. Like the other giant outer planets, Neptune has no solid surface. It also has a system of rings and more than a dozen moons.
    • Diego Hinojosa
      Diego Hinojosa on 04 Nov 14
       
      Neptune is a planet that has a lot of blue. It's atmosphere and also surface is not solid. It also has rings and like 12 moons.
  • Neptune is the smallest of the four giant outer planets. The diameter at its equator is about 30,775 miles (49,528 kilometers), as measured at a level of the atmosphere where the pressure is 1 bar (the pressure at sea level on Earth). This makes it slightly smaller than Uranus but nearly four times as big as Earth. Neptune’s mass is about 1.2 times greater than Uranus’, however, and more than 17 times greater than Earth’s. It is the third most massive planet in the solar system, after Jupiter and Saturn. Like the other outer planets, Neptune has a low density—only about 1.6 times the density of water. However, it is the densest of the four, being roughly 25 percent denser than Uranus.

  • The sleep terror or sleepwalking may last a few minutes to an hour.
  • With sleepwalking, the behavior seems purposeful. The child could be sitting up or getting out of bed, eating or dressing. A sleepwalker often has a blank expression and is difficult to awaken. Sleepwalking is more common in males and is often linked with bedwetting.  About 15% of children 5 to12 years of age walk in their sleep. As with sleep terrors they don’t remember sleepwalking or the behavior the next morning.

gender pink blue girls boys

shared by Nany Rocha on 31 Oct 14 - No Cached
  • But did you know that pink hasn’t always been a colour for girls, or blue for boys? In Michael Kimmel’s outstanding Manhood in America: A Cultural History, he points out that clothing wasn’t colour-coded in America until the early twentieth century, before which little boys and girls were dressed pretty much identically. Even when people started pushing for more gender-specific children’s clothing, there was a huge debate over which colour to assign to which gender. It started out with boys wearing pink or red because the colours were seen to indicate strength, while girls wore blue because they were “flighty” like the sky. From a 1918 editorial called “Pink or Blue” cited by Kimmel:
    • Nany Rocha
      Nany Rocha on 04 Nov 14
       
      Michael Kimmel pointed out that color coding wasn't used in the vintage america.In fact little boys and little girls used to dress up the same way.But then people wanted to make little kids use specific colored clothes.It started with boys wearing pink or red stuff because the colors where supposed to symbolize strength,while girls used blue because it was soft and dainty (Delicate).
  • So basically the colours changed based on which colour was seen to denote the strength of boys and delicacy of girls, but the idea that those traits are inborn and inalienable did not. It’s not just clothes: walk through the girls’ section of any Toys R Us and you’ll see shelf after shelf of pink, pink, pink. While little girls enjoy some leeway to play with blue toys, many boys get mocked if they want to play with pink “girls’ toys” and sometimes their parents and relatives start panicking that they might even grow up to be (gasp) gay. The fact that parents worry about the sexuality of their kids at all is crazy enough in itself, but that’s for another time. Back to colour-coding.
  • If you think boys and girls just forget about coding gender based on colour once they hit puberty, you’d be wrong. Maricopa County Sheriff Joe Arpaio made headlines when he started forcing male inmates to wear pink underwear to humiliate them. He says it’s a deterrent to reoffending because inmates don’t want to come back and be forced to wear pink again. How screwed up is it that we’ve given a colour so much meaning in less than 100 years that it would make grown male criminals tremble just to think about wearing it?
  • ...2 more annotations...
  • his is about more than policing convicts, it’s about policing the boundaries of masculinity and reinforcing homophobia. Kimmel states: “Homophobia is more than the irrational fear of homosexuals…[it] is the fear of other men – that other men will unmask us, emasculate us, reveal to us and the world that we do not measure up, are not real men.” The pink and blue shoe keychains might not seem like a big deal, and indeed most people don’t think twice about them. But imagine how much harder it could be for some trans and intersex people to negotiate a restroom ritual like this. Gender-neutral washrooms are a big step towards fixing this issue, but so is realizing that blue-pink colour coding is just the tip of the iceberg of things we use to arbitrarily divide “masculine” from “feminine”.

      Gender stereotypes are something that might not seem important,but actually it is a bit important because it kind of symbolizes what a girl or boy will or would use as clothes or other things.I really think that all this stereotypes are dum because it actually doesn't make sense.

tongue taste works

shared by Isabel Herrera on 04 Nov 14 - No Cached
  •  The tongue is basically a muscle. This muscle helps the digestive process by doing several things: Move food to the teeth for chewing. Mix saliva into the food. Move food to the back of the mouth for swallowing.
    • Isabel Herrera
      Isabel Herrera on 04 Nov 14
       
      The tongue is a very strong muscle that helps the digestive process by helping the food mix with the saliva, also for the food to go to the back of the mouth for swallowing, and finally it helps the food go to your teeth for you to chew easily. 
  • As mentioned above, the tongue mixes the food with saliva. As the saliva mixes it is also spreading the solutions and chemicals from the food into the grooves between the papillae on the tongue. The taste buds are located on the papillae and the taste receptors respond to the chemicals from the food. When triggered, the receptors send impulses along the nerves in the tongue up to the brain for processing.
    • Isabel Herrera
      Isabel Herrera on 04 Nov 14
       
      The tongue helps the food mix with your saliva, but when it starts mixing it sends food chemicals to the cuts on your papillae. The taste buds are in the papillae and the taste receptors respond to the chemicals of the food. When that happens the brain gets signals of how the food tastes like.

It is the closest planet to Earth, and it is also the most similar to Earth in size, mass, volume, and density. These similarities suggest that the two planets may have had similar histories. Scientists are thus intrigued by the question of why Venus and Earth are now so different.

  • If you've ever watched a jet plane taking off or coming in to land, the first thing you'll have noticed is the noise of the engines. Jet engines, which are long metal tubes burning a continuous rush of fuel and air, are far noisier (and far more powerful) than traditional propeller engines. You might think engines are the key to making a plane fly, but you'd be wrong. Things can fly quite happily without engines, as gliders (planes with no engines), paper planes, and indeed gliding birds readily show us.
