B E C: The New Phase Of Matter
Number of Words: 383 / Number of Pages: 2
... which makes it accessible to physics labs around
the world.
The next step is to test the new phase of matter. We do not know yet if
it absorbs, reflects,or refracts light. BEC is related to superconductivity and
may unlock some mysteries of why some minerals are able to conduct electricity
without resistance. The asymmetrical pattern of BEC is is thought by some
astrophysicists to explain the bumpy distribution of matter in the early
universe, a distribution that eventually led to the formation of galaxies.
Physicists are working on creating an atom laser, using new technology derived
from the BEC ...

Mimicry In Nature
Number of Words: 1457 / Number of Pages: 6
... were being fooled by spiders impersonating ants, squirrels
that look like shrews, worms copying sea anemones, and roaches imitating
ladybugs. There are even animals that look like themselves, which can also
be a form of impersonation.
The phenomenon of mimicry, as it's called by biologists, was first
noted in the mid-1800s by an English naturalist, Henry W. Bates. Watching
butterflies in the forests of Brazil, Bates discovered that many members of
the Peridae butterfly family did not look anything like their closest
relatives. Instead they bore a striking resemblance to members of the
Heliconii ...

... to the
beaker. Check with litmus paper to ensure that it is slightly basic. Fill the
beaker with up to 100 mL mark with distilled water. Heat the solution and allow
it to boil for 5 minutes. Prepare a squirt bottle with hot water. Filter the
solution and rinse the beaker with the hot water. Rinse the filter cake with
hot distilled water. Transfer the filter paper into a clean beaker. Add ~ 10
mL of 3M sulfuric acid to the beaker in order to dissolve the filtrate. Remove
and rinse the filter paper. Now add ~ 0.35 g of zinc powder to the solution and
stir until the solution becomes clear. D ...

Wilderness Required

... on past the two juniper trees
toward the far side of the plateau I found I was feeling sorry
for any man who was not free to abandon whatever futility
detained him and to walk away into the desert morning with
a pack on his back.”
Such experiences allow for one to gain a sense of who they are, not as a superior being, but as one living creature in an expansive world. This is a sense of appreciation for what there is to discover in the wilderness. These discoveries are endless; both scientific and philosophical. Fletcher had found his standing in the world and an appreciation for nature. ...

Genomics

... history, this new company is valued at over $100 billion. A near merger between Glaxo and SmithKline would have created the world’s third largest company, with a budget large enough to fund the estimated cost of sequencing the human genome. Its capitalization would have been larger than the annual gross national product of some 143 of the world’s nations (Enriquez 925).
These mergers also allow the companies to combine their knowledge pools to gain an edge in the race to acquire licensing agreements and patents. In 1991 the U.S. Patent and Trademark Office got 4000 requests for patents on gene se ...

Environmental And Genetic Affects And Schizophrenia
Number of Words: 3889 / Number of Pages: 15
... Association (APA), 1996).
There are many theories about the aetiology of schizophrenia, but research has failed to pinpoint the origins. There is evidence that environmental pathogens (for example, viruses) are involved in the causation of schizophrenia. There is also evidence for a role of hereditary influences and obstetric complications on the incidence of schizophrenia. Furthermore, psychological influences have also been suggested as important in precipitating episodes of schizophrenia (for example, significant life events and interactions within the family). The symptoms and syndrome ...

Is There Evidence That Homosexuality Is Biologically Determined?

... male sexual
orientation. However, there are a few flaws to their interpretation of the
results. Among them are stated in the article. A replication of the
experiment is necessary, the separation of the particular gene has not been
achieved, and the importance of the region has not yet been determined.
Moreover, the supposed gene that influences homosexuality suggests that it
acts indirectly on the choice of their sexual orientation. LeVay and Hamer
mention their perspective on the cause of homosexuality that was derived
from extensive experiments.
Throughout the article, “Evidence for Biolog ...

The Effect Of Temperture On Air Pressure
Number of Words: 1262 / Number of Pages: 5
... the first experiment the procedure is:
1) Heat an ordinary pop can on a hot plate.
2) After about fifteen minutes take the can off the hot plate and put it upside-down in a pan of cold water.
3) Record my observations on a piece of paper.
4) Write my conclusions in my science fair logbook.
For the second experiment my procedure is:
1) Get an empty gallon milk jug at room temperature.
2) Heat to water to just before the boiling point on a hot plate.
3) Fill the milk jug about quarter of the way with hot water.
4) Put the lid on tightly
5) Wait one hour and record ...

Masters Of The Universe

... per second(Intro. to Black Holes 1). This means that to leave the Earth’s gravitational pull, you must be able to travel at least seven miles per second(Intro. to Black Holes 1). To escape a black hole, your velocity must reach at least the speed of light(Intro. to Black Holes 1). Because the speed of light(186,000 miles per second) is not possible because you must have infinite force to achieve the speed of light, nothing can escape a black hole’s gravitational field(Intro. to Black Holes 1). This is why a black hole is a black hole. No light can escape from it, therefore, we c ...

Compressed Gas: Helium

... passes from the blood to the
air. When you hold your breath, the exchange of gases slows, as "stale"
air in the lungs is no longer replaced by "fresh" air. Oxygen is
actually removed from the blood stream during the exchange of gases.
depending on how completely oxygen is replaced by helium, you may lose
consciousness quickly and without warning - you may literally pass out
while still standing. The usual result is an uncontrolled fall that can
cause serious injury, even if normal breathing resumes before brain damage
occurs due to lack of oxygen. This is to inform you that inhaling
heliu ...
