Why is Richard Dawkins left speechless in front of a plain truth ?
“If itcould be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down. So wrote Charles Darwin in `The Origin of Species`, where he made his theory of evolution public. The theory applied materialist philosophy to nature and challenged the consensus that life on earth is the artifact of the Creator. During the following 150 years, many in the scientific community assumed that Darwin had almost accomplished this task. Today, science demonstrates that they were mistaken. Findings in the last two decades alone have shattered the basis of the theory. Key branches of science, such as paleontology, biochemistry, population genetics, comparative anatomy, and biophysics, indicate one after another that natural laws and chance effects proposed by the theory cannot explain the origin of life. Life turns out to be infinitely more complex than Darwin imagined in his time demonstrating that his theory has absolutely broken down.

Chemistry: Dimensional Analysis
www.mindbites.com In this lesson, you will learn how to convert measurements from one unit to another. You will learn how to create a conversion factor, which is always a factor of one that is constructed from a known quality. When creating a conversion factor, you will want to make sure to choose one that allows you to cancel out unwanted units. Prof. Yee also discusses significant figures when using conversion factors. Since conversion factors are considered exact, they have an infinite number of significant figures that are not limited. The data will limit the number of significant figures that you will use in an answer. Objects that are counted are also considered exact with unlimited significant figures. You will learn how to link multiple conversion factors, which is sometimes necessary when converting from one unit to another. Prof. Yee reminds you to make sure you always “”take the units along for the ride”" to ensure that you are finding your answer in the proper units. Finally, you will learn the proper conversion factors for converting both from degrees Farenheit to degrees Celsius and from degrees Celsius to degrees Kelvin. Taught by Professor Yee, this lesson was selected from a broader, comprehensive course, Chemistry. This course and others are available from Thinkwell, Inc. The full course can be found at www.thinkwell.com The full course covers atoms, molecules and ions, stoichiometry, reactions in aqueous solutions, gases, thermochemistry, Modern Atomic …
