Docking With Mir
... June 29, 1995. During launch and ascent, there
wasn't much to think about except the thrill of the ride. Then the tension rose.
In less than thirty-six hours, they would have to close a gap of four thousand
miles at an altitude of 245 miles while traveling at 17,500 miles per hour, only
to have to move within three inches and two degrees of a quickly moving, very
fragile object in space. One small thrust of a poorly aligned engine could cost
one of four space-worthy shuttles and the world's first and only long-term space
station.
Docking was over with soon, and was followed by the cosmonauts of Mir
greeting the astronauts of Atlantis. Gifts of flowers, candy and f ...

Mechanical Energy
... combine
with oxygen from the air, they release their stored energy as heat. We
recognize this process as burning. The individual relies on food for fuel
which contains energy©giving substances that our bodies can store until we
need this energy to use our muscles. When we do use our muscles within us,
we may not always be sure that heat is given off. Our bodies do not burst
into flames but the perspiration on our skin is a clue to what is happening.
The movement of the windsurfer has a different explanation. The
windsurfer is propelled along by a sail which collects mechanical energy
from the winds that sweep along the water. This energy has been produce ...

Cloning 5
... matched life form. The actual merging process between the cells is called Nuclear Transfer. In this process the nucleus of one donor cell is removed and placed into a lab dish and starved of nutrients; it is then placed into a lab dish with a fertilized egg cell. Naturally, the cell that was starved will try to fuse with the healthy cell but it will need a little help. These two cells are then electrified thereby causing the two cells to fuse together combining their genetic structures.

Creationism And Darwinism
... not recognizing the quiet presence of The Scientific Mathematician who set everything into motion around us. We should be in awe, not presumptuous and skeptical.
About 3,000 years ago King David of Israel wrote (Psalm 8:3-4) "When I consider Your heavens, the work of Your fingers, the moon and the stars, which You have ordained; what is man that you are mindful of him? And the son of man, that You visit him?"
Creationism is the product of a literal interpretation of the Biblical story of Genesis. It holds that God created the world in a single act approximately 6,000 years ago--and that human beings, animals, and other forms of life exist today much as they did ...

Afluenza
... is a disease that is sweeping the U.S. at an alarming pace. It is called affluenza it is very contagious and growing at frightening rates. In 1997, an amazing 1.1 million debt plagued spenders filed for personal bankruptcy that was a 28.6% increase from '96. Economists predict another 1.6 million to file by the end of this fiscal year, (Shop 'til We Drop [STWD], 1997). These are two vivid examples of the amazing rate at which affluenza is growing. These numbers are occurring

Alchemy
... in . The Roman emperor Caligula is said to have instituted experiments for producing gold from orpiment, a sulfide of arsenic, and the emperor Diocletian is said to have ordered all Egyptian works concerning the chemistry of gold and silver to be burned in order to stop such experiments. Zosimus the Theban (about AD 250-300) discovered that sulfuric acid is a solvent of metals, and he liberated oxygen from the red oxide of mercury. The fundamental concept of stemmed from the Aristotelian doctrine that all things tend to reach perfection. Because other metals were thought to be less "perfect" than gold, it was reasonable to assume that nature formed gold out of ...

Genome Project
... genetic information identical to the parent cell or organism. Although some organisms produce asexually naturally, the first artificial cloning by humans were plants developed from grafts and stem cuttings. Cloning involving very complex laboratory techniques is a relatively recent scientific advancement in today’s world. Among these is the , which involves the research and support of Physical Mapping and DNA Sequencing. This would enable Humans to reproduce babies that what most parents want. Completing this DNA sequencing and Physical mapping would enable us to change everything in a new born baby to the likes of the parents e.g. IQ, Color, Stren ...

Effects Of Asperguillus
... sources of the fungal spores
could be contaminated or wet wood, bird droppings in air ducts, or decaying
fireproofing materials. The fungus causes pneumonia in a host with a weak or
otherwise compromised immune system. Patients at risk are those undergoing
organ transplant or bone marrow transplants, and depending on the type of
transplant, mortality rates are as high as 95%. Bone marrow transplant patients,
the highest risk group, should be treated like they are immunosuppressed for up
to four weeks after the procedure. The portal of entry is through the upper
respiratory track. The infection then becomes systemic and is spread into
multiple deep organs. ...

Boiling Water
... atmosphere pushing down on the surface of the liquid. As they are heated they gain energy to begin to pull away from one another. When they gain enough energy, they are able to separate and to overcome the force of the atmospheric pressure and form the gas (water vapor) that makes up the bubbles you see in the boiling process. The standard temperature at which this occurs is 100 C or 212 F. In the very early stages of heating, you may see some small bubbles even though the water is only warm. This is some air that is dissolved in the cold water and is being expelled by the heating. This is not boiling. As the water nears the boiling point, some areas of the c ...

Down Syndrome
... unfortunate name on his notion that these children looked like people from Mongolia, who were thought then to have an arrested development. This ethnic insult came under fire in the 1960s from Asian genetic researchers, and the term was dropped from scientific use. Instead, the condition became called "Down's syndrome." In the 1970s, an American revision of scientific terms changed it simply to "," while it still is called "Down's" in Europe.
There are three main types of . The vast majority of children with (approximately 95 percent) have an extra 21 chromosome. Instead of the normal number of 46 chromosomes in each cell, the individual with has 47 chromosome ...
