Powers of 10

Logo for Powers of 10
Java applet to demonstrate scentific notation by examining how a view changes upon magnification. From the site: "View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in single order of magnitudes until you reach an oak tree just outside the National High Magnetic Field Laboratory in Tallahassee, Florida. Then begin to move from the actual size of a leaf into the microscopic world through leaf cell walls, cell nucleus, DNA and finally, into the... More

After going over all of the material in this webiste I found that it took me
about ten to fifteen minutes looking at the information and writing down some
important facts about the powers of ten and what they are capable of. Writing
down some notes was useful to me but there was not as much information as I had
expected. In the other website that I looked at there was more than enough
information that I could write down but this website was limited in its powers
of ten.
I strongly thought that the quality of the content was good but it could
have been much better. The website was fun to look at but it only explained
certain numbers about powers of ten and not the basic numbers. The examples
that were given were about huge global numbers and a multitude of different
things. Some of the information was for a much higher learning of mathematics.
I felt that some information was not as detailed and some information was too
After going over this site I believe that this information will only
enhavce the ability of the teachers and not as much as the student only because
of the fact that teachers have a stonger mind set than student and teachers have
a better understanding of what they are talking about. Teachers are teachers
for a reason and students only go to school to learn different things.
I believe that first time users will have an easy time finding and using
this webiste because it is still easy to follow and the software is also easy to
go by.

The java applet loads with the page and starts the slideshow automatically. It
offers some manual controls to speed up the screen refresh rate and provides
read out of distance in scientific notation. The slideshow is the main thing,
which explains the topic. I spent about 10 minutes browsing and could get a fair
idea of what the author wants to convey.

The website offers some breath taking views moving through 10 million light
years in space towards the Earth in successive orders of 10. The site shows
Exponential notation indicating a convenient way to write very large or very
small numbers. The site also reflects on how scientists look at things using
their eyes and also wide variety of specialized tools that give them extra
capabilities. For instance, some objects are so small that scientists must use
powerful microscopes to see them. Other objects may be very large but are so far
away that scientists have to use a powerful telescope in order to observe them.
Piecing together the information on utilization of the concept of Power of 10
is shown by its application to laws of Physics. This can be used more
appropriately as an example of fractals in real world ? exhibiting fractal
characteristics of self-similarity at different scales.

It?s a hands free tool to understand the Powers of 10 using its application in
optics. It is always easy to remember new concepts when they are related to
something attractive.
