We like to feel superior to the people who lived centuries ago, what with their shitty mud huts and curing colds by drilling a hole in their skulls. But we have to give them credit: They left behind some artifacts that have left the smartest of modern scientists scratching their heads. For instance, you have the following enigmas that we believe were created for no other purpose than to fuck with future generations. The Voynich Manuscript The Mystery: The Voynich manuscript is an ancient book that has thwarted all attempts at deciphering its contents.
It appears to be a real language--just one that nobody has seen before. Translation: "...and when you get her to put the tennis racket in her mouth, have her stand in a fountain for a while. There is not even a consensus on who wrote it, or even when it was written. Why Can't They Solve It? Could you? Don't even try. As you can imagine, proposed solutions have been all over the board, from reasonable to completely clownshit. Our Guess: Why do we believe in electrons, but not in fairies? By Benjamin Kuipers No one has directly observed either electrons or fairies.
Both of them are theoretical constructs, useful to explain observations that might be difficult to explain otherwise. The "theory of fairies" can actually explain more things than the "theory of electrons". So why do we believe in electrons, but not in fairies? Is the issue a political one, where the "electron" fans got the upper hand in the nineteenth century, so by the twentieth century the "fairy" fans were a scorned and persecuted minority? Or, have we proved for sure that fairies don't exist?
No, to both. Fairies are much more free. It's always possible that there really are fairies. The scientific method is an amazing procedure for incrementally improving certain kinds of theories: those that make testable predictions. The theory of evolution is a scientific theory, because it implies a large number of specific testable claims. The theory of intelligent design could be true. Atheism is a religion, too!

Now that 2010 has come to a close, we take a look at the top ten scientific discoveries and breakthroughs of this past year. 10. Scientists find life built with Arsenic An astrobiology research has found the first known organism able to thrive and reproduce using the toxic chemical arsenic, which has changed the fundamental knowledge about what comprises all known life on Earth.
Phosphorus is a central component of the energy-carrying molecule in all cells and also the phospholipids that form all cell membranes. Arsenic, which is chemically similar to phosphorus, is poisonous for most life on Earth. This discovery of a life form with a different biochemistry makeup will alter biology textbooks and expand the scope of the search for life beyond Earth. 9.

Cosmology is study of the Universe in its totality, and by extension, humanity's place in it. Though the word cosmology is recent (first used in 1730 in Christian Wolff's Cosmologia Generalis), study of the Universe has a long history involving science, philosophy, esotericism, and religion. In recent times, physics and astrophysics have come to play a central role in shaping the understanding of the universe through scientific observation and experiment; or what is known as physical cosmology shaped through both mathematics and observation in the analysis of the whole universe. In other words, in this discipline, which focuses on the universe as it exists on the largest scale and at the earliest moments, is generally understood to begin with the big bang (possibly combined with cosmic inflation) - an expansion of space from which the Universe itself is thought to have emerged 13.7 billion years ago. This is the purpose of the ancient metaphysical cosmology.
Cosmology Wikipedia Heber D. Double helix unlocked key to life. By Steve Sternberg, USA TODAY Fifty years ago this week, two brash young scientists in an obscure lab at the University of Cambridge in England unraveled the structure of DNA, the elegant living thread that is the genetic basis of inheritance and evolution. The discovery of the double helix by James Watson, 25, and Francis Crick, 36, on Feb. 28, 1953, unveiled what Crick called “the secret of life.” DNA is the molecule that makes and maintains all life. It enables life to re-create itself. “What we’re learning is totally redefining medicine as I learned it,” says Donald Lindberg, director of the National Library of Medicine. How much DNA does it take to make, operate and maintain a human? Understanding DNA paved the way to gene therapy, DNA fingerprinting, a cloned sheep named Dolly, stem-cell research, genetically engineered crops, research into human origins and evolution and DNA-based medicines.
Outside a narrow circle of geneticists, few took note of the historic discovery. US Genomics. SCIENCE U. Science Review Games and Science Games. Cosmic Explorers By Courtney Brown. Bio.

Leonardo Home Page. Science. Systematic endeavor for gaining knowledge Science is a rigorous, systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the world.[1][2] Modern science is typically divided into three major branches:[3] natural sciences (e.g., biology, chemistry, and physics), which study the physical world; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies;[4][5] and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study formal systems, governed by axioms and rules.[6][7] There is disagreement whether the formal sciences are science disciplines,[8][9][10] because they do not rely on empirical evidence.[11][9] Applied sciences are disciplines that use scientific knowledge for practical purposes, such as in engineering and medicine.[12][13][14] Etymology There are many hypotheses for science's ultimate word origin.
History Early history Classical antiquity. Compétences et formation. Anatomy In 3D. Metaphysical Information on Selenite - Selenite Sword Maker. Selenite’s Inherent Properties Selenite is hydrous calcium sulfate mineral; a form of gypsum crystal also known as Satin Spur and in fine grain form Alabaster.
Selenite is named after the Greek goddess of the moon, Selene because of its soft white light and many metaphysical and healing benefits. The stone is tubular in shape, with striations running along it’s length. Selenite is found in Mexico, South America, USA, Australia and Madagascar and formed in evaporative clay beds and hot springs.
They crystal manifests in ice-like, clear, striated, fine, delicate crystals, and it can grow into either in the v-shape twinning, the fishtail configuration or in a single extended point. Selenite as a Gift of Creation Due to the saltwater formation of selenite and our own saltwater beginnings, we resonate with the very essence of this crystal. The answer is found in the healing energy within this powerful crystal. Healing Properties of Selenite Selenite has a direct effect on the emotional body.

Remember burning magnesium in school? Doing this for the first time as an 11-year-old who has just started secondary school is one of those magical experiences that all students should have. But I'm not convinced that the same is true of all practical work carried out in school science lessons. Practical lessons are popular with both students and teachers.
But their popularity with students may lie in the fact that they are less demanding than theory lessons. The same may be true for teachers - after all, it's easier to check that a child has lit his or her bunsen correctly than it is to check that he or she has fully grasped the particle theory of matter, it's easier to teach a child how to connect an ammeter than teach a correct understanding of electric current. Indeed, a study of student teachers reported in this month's School Science Review found that "most were approaching it as a means of lower order learning objectives such as names of equipment and use of standard procedures".

Science can be glorious; it can bring clarity to a chaotic world. But big scientific discoveries are by nature counterintuitive and sometimes shocking. Here are ten of the biggest threats to our peace of mind. 1. The Earth is not the center of the universe. We’ve had more than 400 years to get used to the idea, but it’s still a little unsettling. . … his contemporaries found his massive logical leap “patently absurd,” says Owen Gingerich of the Harvard-Smithsonian Center for Astrophysics. Galileo got more grief for the idea than Copernicus did. 2. Antibiotics and vaccines have saved millions of lives; without these wonders of modern medicine, many of us would have died in childhood of polio, mumps or smallpox.
The influenza virus mutates so quickly that last year’s vaccination is usually ineffective against this year’s bug. 3. The concept of extinction took a while to sink in. Today, according to many biologists, we’re in the midst of a sixth great extinction. Next Generation Science Standards. Popular Science | New Technology, Science News, The Future Now.

BUILDING BIG: Dam Basics. With the exception of the Great Wall of China, dams are the largest structures ever built. Throughout history, big dams have prevented flooding, irrigated farmland, and generated tremendous amounts of electricity. Without dams, modern life as we know it would simply not be the same. Since the first large-scale dam was built in Egypt more than 5,000 years ago, engineers have devised various types of dams to withstand the forces of a raging river. Arch dams... are good for narrow, rocky locations. They are curved, and the natural shape of the arch holds back the water in the reservoir. Arch dams, like the El Atazar Dam in Spain, are thin and require less material than any other type of dam. Sneak a peek at the forces that affect arch dams. Embankment dams... are the most commonly built dams in the United States.
Check out the forces that affect embankment dams. All dams -- whether they're embankment, buttress, arch, or gravity -- must be maintained as they get older. BUILDING BIG: All About Dams. Interactive Simulations. Lesson Plans. Chapter 1: Matter—Solids, Liquids, and Gases Students are introduced to the idea that matter is composed of atoms and molecules that are attracted to each other and in constant motion. Students explore the attractions and motion of atoms and molecules as they experiment with and observe the heating and cooling of a solid, liquid, and gas.
Chapter 2: Changes of State Students help design experiments to test whether the temperature of water affects the rate of evaporation and whether the temperature of water vapor affects the rate of condensation. Students also look in more detail at the water molecule to help explain the state changes of water. Chapter 3: Density Students experiment with objects that have the same volume but different mass and other objects that have the same mass but different volume to develop a meaning of density.
