Solar System - Facts and Information about the Planets and Solar System - 0 views

  • At the heart of the solar system is our sun. The four planets nearest it are rocky, terrestrial worlds — Mercury, Venus, Earth and Mars. After that are four gas giants — Jupiter, Saturn, Uranus and Neptune. Between the orbits of Mars and Jupiter lies the asteroid belt, which includes the dwarf planet Ceres. Beyond the orbit of Neptune one finds the disk-shaped Kuiper belt, in which dwarf planet Pluto resides, and far beyond that is the giant, spherical Oort Cloud and the teardrop-shaped heliopause. See the structure of the solar system (infographic).

The Planets in Our Solar System in Order of Size - 0 views

  • What also is amazing is the sheer size difference of planets. While humans think of Earth as a large planet, in reality it is dwarfed by the massive gas giants lurking at the outer edges of our Solar System. This article explores the planets in order of size, with a bit of context as to how they got that way.
    • Diego Hinojosa
       
      Earth can be thought by us people. By a giant planet but in reality it is really little. In our solar system. The biggest planets on the whole solar system are Jupiter and also saturn they both are "gas giants."
  • No human was around 4.5 billion years ago when the Solar System was formed, so what we know about its birth comes from several sources: examining rocks on Earth and other places, looking at other solar systems in formation and doing computer models, among other methods. As more information comes in, some of our theories of the Solar System must change to suit the new evidence.

      On 1999 to 2003 34 more moons of jupiter were discovered.
  • The moons' physical and orbital characteristics vary widely. The four Galileans are all over 3,100 kilometres (1,900 mi) in diameter; the largest Galilean, Ganymede, is the ninth largest object in the Solar System, after the Sun and seven of the planets (Ganymede being larger than Mercury). All other Jovian moons are less than 250 kilometres (160 mi) in diameter, with most barely exceeding 5 kilometres (3.1 mi). Orbital shapes range from nearly perfectly circular to highly eccentric and inclined, and many revolve in the direction opposite to Jupiter's spin (retrograde motion). Orbital periods range from seven hours (taking less time than Jupiter does to spin around its axis), to some three thousand times more (almost three Earth years).

Solar System Exploration: Planets: Jupiter: Rings - 0 views

  • All four giant planets in our solar system, including Jupiter, possess a system of rings. Unlike the brilliant, icy rings of Saturn, Jupiter's rings are tenuous, dusty structures. And although Saturn's iconic rings were first spied by Galileo in 1610, Jupiter's faint rings were not spied until the 1970s, when spacecraft first visited the Jupiter system.
    • Esteban Cantu
       
      All gas giants in our solar system have rings. Jupiter's rings aren't similar to saturn's, because they are made out of ice and jupiter's appear to be made out of dust. jupiter's rings were discovered in 1970.
  • The rings appear to be created by dust thrown off by impacts on small moons that orbit within them. The gossamer rings actually outline the orbits of the moons Amalthea and Thebe. The moons Adrastea and Metis skirt through the outer edges of the main ring.
    • Esteban Cantu
       
      Scientist believe that jupiter's rings were created by dust that has fallen off some of jupiter's moons by impacts.

Why is a minute divided into 60 seconds, an hour into 60 minutes, yet there are only 24... - 0 views

  • Thanks to documented evidence of the Egyptians' use of sundials, most historians credit them with being the first civilization to divide the day into smaller parts. The first sundials were simply stakes placed in the ground that indicated time by the length and direction of the resulting shadow. As early as 1500 B.C., the Egyptians had developed a more advanced sundial.

      Thanks to the duodecimal system. The  egyptians used the system to make counting more easier. Also the number 12 is typically attributed.
  • A T-shaped bar placed in the ground, this instrument was calibrated to divide the interval between sunrise and sunset into 12 parts. This division reflected Egypt's use of the duodecimal system--the importance of the number 12 is typically attributed either to the fact that it equals the number of lunar cycles in a year or the number of finger joints on each hand (three in each of the four fingers, excluding the thumb), making it possible to count to 12 with the thumb.
  • The next-generation sundial likely formed the first representation of what we now call the hour. Although the hours within a given day were approximately equal, their lengths varied during the year, with summer hours being much longer than winter hours

  • Egyptian astronomers also first observed a set of 36 stars that divided the circle of the heavens into equal parts. The passage of night could be marked by the appearance of 18 of these stars, three of which were assigned to each of the two twilight periods when the stars were difficult to view. The period of total darkness was marked by the remaining 12 stars, again resulting in 12 divisions of night (another nod to the duodecimal system).

      Egyptians noticed that there was 36 stars in each part so they divided that into equal parts 12.

NASA - What Is Jupiter? - 0 views

  • Jupiter is the largest planet in the solar system. It is approximately 143,000 kilometers (about 89,000 miles) wide at its equator. Jupiter is so large that all of the other planets in the solar system could fit inside it. More than 1,000 Earths would fit inside Jupiter.

Neptune -- Britannica School - 0 views

  • 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
       
      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.

Blood Flow - HowStuffWorks - 0 views

  • All blood enters the right side of the heart through two veins: The superior vena cava (SVC) and the inferior vena cava (IVC) (see figure 3).The SVC collects blood from the upper half of the body. The IVC collects blood from the lower half of the body. Blood leaves the SVC and the IVC and enters the right atrium (RA) (3).When the RA contracts, the blood goes through the tricuspid valve (4) and into the right ventricle (RV) (5). When the RV contracts, blood is pumped through the pulmonary valve (6), into the pulmonary artery (PA) (7) and into the lungs where it picks up oxygen.

Uranus -- Britannica School - 0 views

  • Uranus is the third largest planet in the solar system, after Jupiter and Saturn. Uranus is about four times bigger than Earth. Its diameter at the equator is about 31,763 miles (51,118 kilometers), as measured at the level of the atmosphere where the pressure is the same as at sea level on Earth. The planet is slightly larger than Neptune, but Neptune is about 1.2 times more massive. Uranus’ density is quite low—only about 1.3 times that of water, compared with 1.6 for Neptune and 5.5 for rocky Earth.

Clocks - How Time Works - 1 views

  • 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
       
      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:
  • ...3 more annotations...
  • 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
       
      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:

Why are there 24 hours in a day? › Ask an Expert (ABC Science) - 0 views

  • "The origin of our time system of 24 hours in a day with each hour subdivided into 60 minutes and then 60 seconds is complex and interesting," says Dr Nick Lomb, consultant curator of astronomy, from the Sydney Observatory.
  • Our 24-hour day comes from the ancient Egyptians who divided day-time into 10 hours they measured with devices such as shadow clocks, and added a twilight hour at the beginning and another one at the end of the day-time, says Lomb.
  • "Night-time was divided in 12 hours, based on the observations of stars. The Egyptians had a system of 36 star groups called 'decans' — chosen so that on any night one decan rose 40 minutes after the previous one.
    • marino5856
       
      The 24 hours has been invented by the egyptians. They first divided it into 10 hours but then they divided it in 12 because of the twilight. So night time was divide in 12 hours because they wanted to see the stars in the night and also that there would be light in the day.
  • ...3 more annotations...
  • The subdivision of hours and minutes into 60 comes from the ancient Babylonians who had a predilection for using numbers to the base 60. For example, III II (using slightly different strokes) meant three times 60 plus two or 182.
  • "We have retained from the Babylonians not only hours and minutes divided into 60, but also their division of a circle into 360 parts or degrees," says Lomb.
  • While each country has (in broad terms) historically had distinct measurements for distance, weights etc the method of splitting the day into 24 hours, one hour into 60 mins and one minute into 60 seconds seems to be the only one in use, and indeed to me the only one I know of. This non-metric measurement of time is far from ideal, but what other comparably accurate methods have been used historically?

Saturn -- Britannica School - 0 views

  • Saturn was named after the ancient Roman god of agriculture. His counterpart in ancient Greek mythology was Cronus, the father of Zeus (the counterpart of the Roman god Jupiter). The planet Jupiter is Saturn’s nearest neighbor and the closest to it in size and composition. Like Jupiter, Saturn is a giant world formed mainly of hydrogen with no solid surface. It has a massive atmosphere, or surrounding layer of gases, with complex weather patterns. ESA/NASA/JPL/University of ArizonaESA/NASA/JPL/University of Arizona The planet’s extensive system of icy moons includes nine major moons and dozens of small ones. Some of the moons help create the rings and maintain their shape. Titan, the largest of Saturn’s moons, is bigger than the planet Mercury. It is the only moon in the solar system known to have a dense atmosphere.

hour (unit of time) -- Encyclopedia Britannica - 0 views

  • in timekeeping
  • 3,600 seconds, now defined in terms of radiation emitted from atoms of the element cesium under specified conditions. The hour was formerly defined as the 24th part of a mean solar day—i.e., of the average period of rotation of the Earth relative to the Sun. The hour of sidereal time, 1/24 of the Earth’s rotation period relative to the stars, was about 10 seconds shorter than the hour of mean solar time.
    • marino5856
       
      It also has 24 hours the earth because in the system of the egyptians it said that it also has 24 hours because of the earth spinning.
  • In even earlier systems of timekeeping, an hour was 1/12 of a period of daylight or darkness—hence, variable in length with seasonal changes in the length of day and night. The custom of dividing the cycle of day and night into 24 periods seems to have originated with the ancient Egyptians.

Jupiter - 0 views

  • Jupiter has a very faint ring system, but is totally invisible from the Earth. (The rings were discovered in 1979 by Voyager 1.) The atmosphere is very deep, perhaps comprising the whole planet, and is somewhat like the Sun. It is composed mainly of hydrogen and helium, with small amounts of methane, ammonia, water vapor and other compounds. At great depths within Jupiter, the pressure is so great that the hydrogen atoms are broken up and the electrons are freed so that the resulting atoms consist of bare protons. This produces a state in which the hydrogen becomes metallic.

The Healing Properties of Tears: 7 Good Reasons to Cry Your Eyes Out - Beyond Blue - 0 views

  • 1. Tears help us see. Starting with the most basic function of tears, they enable us to see. Literally. Tears not only lubricate our eyeballs and eyelids, they also prevent dehydration of our various mucous membranes. No lubrication, no eyesight. Writes Bergman: “Without tears, life would be drastically different for humans–in the short run enormously uncomfortable, and in the long run eyesight would be blocked out altogether.”
  • 2. Tears kill bacteria. No need for Clorox wipes. We’ve got tears! Our own antibacterial and antiviral agent working for us, fighting off all the germs we pick up on community computers, shopping carts, public sinks, and all those places the nasty little guys make their homes and procreate. Tears contain lysozyme, a fluid that the germ-a-phobic dreams about in her sleep, because it can kill 90 to 95 percent of all bacteria in just five to 10 minutes! Which translates, I’m guessing, to three months’ worth of colds and stomach viruses.
  • 3. Tears remove toxins. Biochemist William Frey, who has been researching tears for as long as I’ve been searching for sanity, found in one
  • ...5 more annotations...
  • study that emotional tears–those formed in distress or grief–contained more toxic byproducts than tears of irritation (think onion peeling). Are tears toxic then? No! They actually remove toxins from our body that build up courtesy of stress. They are like a natural therapy or massage session, but they cost a lot less!
  • 4. Crying can elevate mood. Do you know what your manganese level is? No, neither do I. But chances are that you will feel better if it’s lower because overexposure to manganese can cause bad stuff: anxiety, nervousness, irritability, fatigue, aggression, emotional disturbance and the rest of the feelings that live inside my happy head rent-free. The act of crying can lower a person’s manganese level. And just like with the toxins I mentioned in my last point, emotional tears contain 24 percent higher albumin protein concentration–responsible for transporting many small molecules (which has to be a good thing, right?)–than irritation tears.
  • 5. Crying lowers stress. Tears really are like perspiration in that exercising and crying both relieve stress. For real. In his article, Bergman explains that tears remove some of the chemicals built up in the body from stress, like the endorphin leucine-enkaphalin and prolactin, the hormone I overproduce because of my pituitary tumor that affects my mood and stress tolerance. The opposite is true too. Bergman writes, “Suppressing tears increases stress levels, and contributes to diseases aggravated by stress, such as high blood pressure, heart problems, and peptic ulcers.
  • 6. Tears build community. In her “Science Digest” article, writer Ashley Montagu argued that crying not only contributes to good health, but it also builds community. I know what you’re thinking: “Well, yeah, but not the right kind of community. I mean, I might ask the woman bawling her eyes out behind me in church what’s wrong or if I can help her, but I’m certainly not going to invite her to dinner.” I beg to differ. As a prolific crier, especially on video, I always come away astounded by the comments … the resounding support of people I know all that well, and the level of intimacy exchanged among them. Read for yourselves some of the comments on both my self-esteem video and my recent death and dying video and you’ll appreciate my point. Tears help communication and foster community.
  • 7. Tears release feelings. Even if you haven’t just been through something traumatic or are severely depressed, the average Jo goes through his day accumulating conflicts and resentments. Sometimes they gather inside the limbic system of the brain and in certain corners of the heart. Crying is cathartic. It lets the devils out. Before they wreak all kind of havoc with the nervous and cardiovascular systems. Writes John Bradshaw in his bestseller “Home Coming”: “All these feelings need to be felt. We need to stomp and storm; to sob and cry; to perspire and tremble.” Amen, Brother Bradford!

Automobile safety - Wikipedia, the free encyclopedia - 0 views

  • Automobile safety is the study and practice of design, construction, equipment and regulation to minimize the occurrence and consequences of automobile accidents. Road traffic safety more broadly includes roadway design. One of the first formal academic studies into improving vehicle safety was by Cornell Aeronautical Labs of Buffalo, New York. The main conclusion of their extensive report is the crucial importance of seat belts and padded dashboards.[1] However, the primary vector of traffic-related deaths and injuries is the disproportionate mass and velocity of an automobile compared to that of the predominant victim, the pedestrian.[citation needed] In the United States a pedestrian is injured by an automobile every 8 minutes, and are 1.5 times more likely than a vehicle's occupants to be killed in an automobile crash per outing.[2]
    • guzman5862
       
      In the cars you need to be safe and they are made like that for a reason so that you are safe and for the system inside the car is safe. A lot of persons have been dead for the cause of trafic because they get too much desperate that they try to go fast but they crash, thats why they had decided to make sit belts. The system inside the car is really little and thats why the car has a lot of things around it and the car is made like that for a reason like an oval so that they crash them with the car is suposed to not happen anything.
