Artwork from human bone

This home displays-displays are the work of Francois Robert who spent hundreds of hours to produce works of art. He called these works with the theme "Stop the violence". He bought the human bones were in the mid 90's from an old school auction.

The horrible part is the artwork is made from human bones truth, once again the bones of truth, not a fake bone.

Misguided On Science

There are some misunderstandings in the implementation of science in public that need to be corrected truth.Here there are approximately 10 misconceptions about science circulating in the community.
1. Water IS blue, not Just Because of the sky(Blue colored water is not due simply reflections of the sky)

Many believe that the lakes and the ocean blue "Only" because they reflect the blue sky. Actually, the water looks blue because they are really blue. Water molecules absorb light, and they absorb red frequencies more than the frequency of blue, so blue frequency appear on the surface. Its effect is small, so the blue color only becomes obvious when observing layers of water dense enough or deep. In salt water or mineral springs, the color of dissolved minerals can be seen.
Sky-reflection does provide a role for the blue ocean, but only when surface water is very calm, and only when the water was observed at a glancing angle less than approximately 10 degrees.
2. Electricity does NOT travel at the speed of light(Electric / electricity does not move at the speed of light)

Many textbooks claim that electricity (electrons) flow through the cable runs at the speed of light. The fact is, the electrical energy which flows rapidly (which is still slower than the speed of light). Electrons, which have mass, can move at the speed of light by using the theory of relativity. The speed of the charge in an electric current is very slow, around several centimeters per hour. In places where electric currents can be seen, as in electrophoresis, slow movement of charge carriers can be seen directly.
3. Seasons are NOT the same length(Season deemed to have the same time period)
Because the Earth moves faster in its orbit as it approaches the sun, summer in the southern hemisphere / winter in the northern part of the earth is the shortest time for the season, with summer in the north or south of the longest winter. However, the difference is only of a few days, while on Mars with its more eccentric orbit, the difference was great.
4. You WILL NOT get a cold just from low temperature(You will not get flu from the cold only)

Has become a widespread misconception in the public that the common cold can be caused by cold weather. In reality, the common cold is caused by a virus and has nothing to do with the low temperature / cold.
5. Saturn is NOT the only planet with rings(Saturn is not the only planet that has the ring)Jupiter, Uranus, and Neptune also have rings around it, although in Saturn's rings are the most obvious and easily seen.
6. Meteors are NOT hot Pls They land on Earth(Meteor is not hot when it landed on earth)

When a meteor lands on Earth, meteors are usually not as hot as most meteors in Hollywood movies. Usually warm. Meteor velocity enough to melt its outside layer, but the material that melts quickly separated, and the interior of the meteor does not have time to heat up because rocks are poor conductors of heat.
7. Clouds do NOT form Because of the water's temperature(The cloud is not formed due to the influence of air temperature)


Is the knowledge that one that clouds form because cold air "holds" less moisture than warm air. Air does not have the capacity to hold moisture. Only the temperature of the water itself (and vicinity) which causes the humidity, condensation process, and then the formation of clouds.8. People DID know the earth was not flat before Columbus(People already knew the earth was not flat before Columbus)

Some believe that Christopher Columbus had difficulty in receiving support because the people of Europe believe that the earth was flat. In fact, sailors and navigators of the time knew that the earth is round, but (true knowledge) disagreed with Columbus on the estimation of the distance to India. If America does not exist, and Columbus went on his journey to India which in fact, he will not be able to last a long time to achieve it.
9. The Great Wall of China is NOT particularly visible from space(Great Wall of China is not visible from space)

At the time in low orbit, the Great Wall of China can be seen from outer space but not unique from the digembor-heralded. From low earth orbit, many artificial objects are visible on earth, not just the Great Wall of China. Highways, ships at sea, dams, railroads, cities, fields, and several buildings.
As to the claim that the Great Wall of China is a man-made object visible from the moon, Apollo astronauts have reported that they did not see any human-made object from the moon.
10. There is NO "dark side" of the Moon(There is no dark side (which is always dark) of the month)

Months in orbit synchronous (synchronous orbit), this means that, in menmbutuhkan exactly the same time to rotate once on its axis with the rotation of the earth. So far the moon has a side / rear / dark / outside, because it always gives the same surface to the earth when it rotates. When the moon is estimated to be between the Sun and Earth, it dalah time "day" on the far side / outside / back of the moon and the night time for the side facing the earth. When the Earth between the Sun and the Moon, a much experienced the "night" and "daylight" to the face of the earth.
