' work on planetary motion stood an a very high mathematical level
for his times. His theory explained how all the celestial bodies move around
the Sun. It took Nicolaus 30 years of mathematical research to form a theory
about planetary motion. The three most popular instruments which
used were quadrant, armilla, and triquetrum. All furnish some measure of the
position of the heavenly body. It took an endless amount of mathematical
calculations to come up with the Copernicus' theory. He had to find out how
fast the Earth spins around the Sun, and how far the ...
The individual unruly cell that has escaped the normal regulatory control mechanisms is the basic unit of cancer. Inside the nucleus is a substance called DNA, which contains genetic information for the body, organized in units called genes. These genes contain the complete plans for the body. They determine weather you have a blue or a green eye,...

Creatine, Beneficial or Waste of $$$$$? Having finally resolved to work out at the gym, you sweat and toil for weeks on end only to look in the mirror and see little to show for it. It's the paradox of the New Year's resolution exerciser. Seeing physical results can help exercisers stay true to their fitness programs, yet for many it takes month...
Leo Boerstoel Mrs. Fuller AP Biology Period 6 9/24/12 Pre-Lab Activity: Flowers Pine Ferns Moss Hypothesis: If the new species has a vertebrae, then it will be located in between the crocodilians and the birds on he cladogram. Methods: After forming our hypothesis, we looked up each gene sequence separately. We wrote down the top three mo...
Rain is an essential ingredient for life. The water provided by rain allows all life on Earth to survive. It waters our crops, allowing us to grow food for us to eat and food for the animals we raise for meat and milk. Although rain is naturally acidic it is being increasingly acidified by pollution from our homes, factories, power stations and c...
