Spiral Prompt

Blogging Prompt
Isn't this a beautiful picture? It's a picture of a giant sea shell in the Phuket Seashell Museum in Thailand. Have you ever seen this type of spiral shape before? It pops up in many places in nature. It's called a "Logarithmic Spiral." A successful response to this Blogging Prompt (you will earn your blogging mark) will answer ALL of these questions:

  1. What is a logarithmic spiral? Write it in your own words, don't copy and paste. ;-)
  2. What does it have to do with logarithms? i.e. Why is it called a Logarithmic Spiral? (Hint: Find out how it is different from an "Archimedian Spiral." Knowing what exponential functions have to do with it will help too.)
  3. Find a picture, not of a seashell, that illustrates a logarithmic spiral in nature. Post it with your reply.

Have fun with this one!

wow this is my first time on the blog and i think am starting to get a hang of it....
so to answer the blogging prompt i would say that a logarithmic spiral is a growth that increases by equal amounts, same ratio.it somewhat starts small and ends big and if you were to follow it you'd cover an infinite distance.
it also differs with the archimedean spiral in that its the same through out.its winding is constant.
check out some cool logarithimc shells here....

That's a great start! Two things, I need to know your name (first name only please) to credit your work, and you're very close to getting the blogging mark for answering this prompt. You just need to do two more things:

(1) Explain what this has to do with logarithms, and
(2) post a picture that is not a sea shell. ;-)

Don't stop now .... you're sooo close to your first blogging mark!
