So in my calculus III class, we're learning how to solve multiple integrals. I like to write about what I'm learning in my math classes, but I don't really have a lot of application for this. So, I decided to expand on my favorite integral. Here is my result:

For those of you who can solve this, go ahead—it's fun. But for those of you who can't, let me walk you through it. We first solve the inside most integral.

Substitute this back...

Now solve the inside integral again...

Substitute this back... (math is sometimes a lot of 'rinse and repeat')

Now, solve the finial integral...

There you have it. Mathematically I've shown that if you use the correct limits of integration, and do so three times (i.e. if you do it right) then can end up being 69. Don't get it? Then try and read the letters of the previous equation. Yep, I've learned so much now that I am attending a university raked in the top 20 in the country, I'm making licentious innuendos using math for lack of anything else to demonstrate.

 I would like to take this moment to thank my awesome high school calculus teacher for making all of this simple and undaunting . . . Thank God. Everyone is capable of 'higher' maths, it's just bad teachers who don't know what they're doing and make it seem impossible for most people.

I didn't get a single trick-or-treater this evening--guess that means I get to eat all the candy I was going to give them.  Spent most of the evening preparing a study guide for an exam on Wednesday with scary movies in the background.
Just for the heck of it, I decided to give myself a typing speed test.  I did two tests, and both placed me over 60 words/min.  I can live with that.

Maggie, Amber, October and I went on our annual trip to the Pumpkin Patch and Edward's Apple Orchard.  It is a trip I look forward to all month, and it was a lot of fun.  We had origionly planned to do this trip last weekend, but had to cancel.  With rain forecast for tomorrow, I knew we had to do the trip today.  It was chilly, but the skies were sunny and the fall colors still in full effect.
This year's trip was also made by little October.  She likely won't remember this trip (or the next couple), but she seemed content sleeping through most the day.

Show tonight at the Disaster House in Rockford.  The DH crew has a fine punk house, and they often put on good shows.  Pictured is myself, Chelsea (whom is playing with my hair), and Luca (in the bottom right corner) all squished onto a couch in the basement.  Picture by Crystal.

Pictured is a wind turbine in the Blue Sky Green Field wind farm.  There were two wind farms on the way to Manitowoc, and this one was very close to us.  As we approached, Amber asked if we get closer to one of the turbines—something I had very much wanted to do. Although I have stopped at two wind farms in the past, I've never been next to a turbine while it was running, and had always wondered how it sounds.  With a steady breeze, all the turbines were turning steadily.  Doing a simple second count, I estimated they were turning about 15 RPM.  After reading about the field, I found I was fairly close—they turn at 14.4 RPM.
After a fuel stop, we found our way to the pictured turbine.  Standing about 100 feet from the tower, I could hear a slight "swoop" sound as the blades went by, but it was more faint than the sound of the wind in the corn field we were surrounded.  After taking a couple pictures, Amber and I discovered something that turned out to be a lot of fun.  Looking directly up at the spinning turbine, you could see a massive 134 foot (40 meter) blade coming directly down at you, then turn up and out of the way.  We both laid down on the ground to stair up at this phenomena—it  was like being on a carnival ride.
This tower stands 162 feet (50 meters), and can generate 1,650,000 watts.  Under the tower you couldn't hear the passing of the blades, nor the 60 Hz hum of the transformer over the sound of the wind.  I was already a fan of wind power, but this experience has made me even more so.  What a great way to make electricity.

 Wind power definitely does kick butt! Problem is, only a few lucky areas have strong winds during peak power usage - if the wind is blowing at 3AM, the power company can't use it very effectively. Nice photos!

Amber and I went to Manitowoc for the day and visited the Wisconsin Maritime Museum.  Despite a strong wind and a touch of rain, we also walked out to the Manitowoc Breakwater Lighthouse.
