62). Disruptive Technologies – Part 1: How music editors are related to steam engines By : Anh Tuan Nguyen
I am not into technologies, those that change so ever fast, and always. But I do observe technological trends, along which the development of scientific applications revolves.
And of all trends, perhaps disruptive technologies are the defining path of industrial implications, a linear passage that technological progress almost invaria...

69). Evolution Theory And Humans' Nature By : Jim Thio
We all learn evolution theory in schools. Well most of us do.
However, what's taught in schools are just basic. What most people, especially religious fundamentalists do not want you to know is that evolution theory can very naturally explain human nature.
It's not in school. So I'll tell you here. I'll start from the leas...
70). Desert Problem For Young Earth Creation Science By : Greg Neyman
Young-earth creationists have a problem. According to their creation model, all the fossil-bearing rock layers in the world need to be created during the Flood of Noah. Fossils, in ancient rock layers, imply that death occurred before the Fall of man, which is contrary to their interpretation of Scripture.
The most visible rock layers ...

73). Can we pull the moon to Earth? By : hello
Theoretically, if we send enough electrons to the moon, we can pull the moon to Earth. This is, maybe a realistic solution for our over populated, energy hunger near future.
If we start to beam electrons to the moon, it's only a matter of time before the moon starts to accelerate to Earth. The attraction force between the positive Eart...
74). What Judges Look for In Science Fair Projects By : Professor Know
Science fair judges have specific things in mind when they review projects. Sure, they like interesting pictures, colorful displays and seeing clever ideas, but they also look for other, more specific, technical features.
Let's take a peak at some grading sheets from a few science fairs.
One school used a point system to ...
75). Learn More about Diamonds By : Dana_CC
A Diamond is a mineral made of carbon that is crystallized. In fact a diamond is more than 99.95% pure carbon. The remaining 0.05 percent of the elements often influences the crystal's color and shape. The diamond is also by far the hardest natural substance known to man. Diamonds form between 75 and 120 miles below the earth's surface. Only at the...
