Wood Whittlings

So I like math. And geometry. And wood whittling. So what better way to waste spend time than by wood whittling geometric some shapes that I love?

I'll begin with the Steinmetz Solid, where the view from the front, side, and top is a circle, but the shape is not a sphere. 

Mathematical Steinmetz solid

I decided I wanted one, so I bought some wooden cubes, sandpaper, and a whittling knife from a hobby store and went to town. And here's my finished hand-carved whittle! How does it compare to the shape above?

From here it's like a cube...

But from here it's like a circle

One nice property of the solid is that it can always roll since it is circular in three dimensions (pardon the music, YouTube gave me no choice since I had to replace the malfunctioning audio).


Now the Steinmetz solid is an interesting structure, but not a very complicated one. The shape is fairly simple, especially compared to the Gömböc, which was only recently discovered in 2006 in a mathematics publication. 

The Gömböc's claim to fame is that it only has one stable point, and is therefore the first homogeneous (same density thoughout) self-righting shape. There are other self-righting shapes that you may know, but these have a weight in the bottom, which the Gömböc doesn't have (that's why it's called homogeneous).

The Gömböc

 For a while I wanted to buy one online, which would be pretty sweet if the cheapest one didn't cost 149 Euros. So I decided to make it. Since it is a much harder shape to whittle, I had to do some planning. 


Whittling in progress

I have to admit, I was first dissuaded by quotes like this,

"The geometry has to be manufactured to unprecedented precision: a Gömböc of 10 cm diamater has tolerances far less than 0.1mm."-Official Website
In imperial units, that's like saying a Gömböc 1 foot wide would have an error tolerance of less than 0.012 inches! 

But alas, after several solid days of whittling and sanding, it was done! In your face, website!

Finished!

Here is my second baby in action. Notice how it self-rights.



Lastly I decided to snap some shots of what I've been working on for so long. To the right is the original 2'' cubes I bought from Hobby Lobby, in the middle is the Steinmetz Solid, and to the right is my Gömböc.



My Babies

Fortunately (for my sanity) these were the only shapes that I have ever wanted to own, so I did not make any other 3-D shapes. But after whittling the Gömböc, with it's unparalleled required precision, I feel like I can make anything I truly want to. I wonder what I'll do next...

West Virginia 2012: Food, Dogs and... Abandoned Structures?

Last weekend I decided (at the suggestion of my dad) to drive to West Virginia while my immediate family visited Aunt Shelly and Larry. I think the surprise went well!

I made it!

Most everyone was happy to see me, although my mom said she hates surprises and that she thought of punching me (fortunately she did not).

I missed you guys too.

Anywho, lets get this post rolling.

Food

It wouldn't be West Virginia without lots and lots of delicious food. Dad and Larry treated us all to a delicious hunk of meat. That's when Larry showed me the magic that is Borsari, the most delicious meat rub ever made. It turns meat into magic.

Besides our delicious chunk of meat, the biggest foodie development to happen in West Virginia was the arrival of the new automatic ice cream maker.

Aunt Shelly's new #1 Ice Cream Maker

We made serious amounts of ice cream. Vanilla, peanut putter, chocolate, hand-picked berry flavor and more.

One of the many flavors we made.

As for eating out, we went to a "take out" place called Smoke on the Water which featured smoked shrimp, ribs, brisket, and best of all smoked potato salad.

Smoke on the Water

Last but not least, we also joined several of our neighbors in a delicious Pig Roast. I've been to Pig Roasts before, but I was told this pig was squealing the day before, which did make this unique.

Can't have a Pig Roast without a roast pig.

Below was our gracious host cutting the pig in the hot West Virginia sun. Since he was preoccupied with cutting the pig, he had others tend to his sweaty forehead to make sure our pig had only the intended flavors.

Give this man a paper towel!

The food at the pig roast was delicious, and it was fun talking to the others who made it. It felt like a traditional rural get-together.

Dogs

Watching the bears running around the forest is one on life's simple pleasures. One of our favorite developments was seeing how far we could get Honey Bear into the water. Honey Bear hates being in water, but Aunt Shelly used some delicious chicken to gave Honey Bear an offer she couldn't refuse.

Honey Bear's pretty cautious.

Almost there!

Got it!

Honey Bear never got deep enough to swim, but she did get most of her belly wet, which was a big step forward. Kudos to Aunt Shelly for being so patient.

Abandoned Structures

Larry introduced us a new tower in Elkins which used to be a lookout for forest fires.

Bickle Knob Observation Tower

The view from the top was truly breathtaking. We could a 360° view of the surrounding area, with all the mountains and valleys creating a real-life contour map of the West Virginia forest.

What a view!

Nick and Aunt Shelly weren't keen on climbing the high, abandoned tower. They made themselves at home in the middle on the floor.

Aunt Shelly and Nick Played it safe.

But they did cowboy'd up to take a nice picture against the railing.

The fam'

My favorite new discovery this trip though was visiting an abandoned property that Aunt Shelley owns, which had fallen into disrepair. Dad and I first drove next to it during one of our Fat Cat rides.

It ain't West Virginia without Fat Cats.

I asked my dad what he though happened, and as he said it, "water just gets everywhere, and destroys everything."

One of Aunt Shelly's more neglected Properties

On our second trip back, we brought mom, who surprised me by coming in and exploring with us.

Mom treading lightly.

Dad, despite being the largest of us all, actually was the only one who managed to not step through the floor. He knew how to distribute his weight.

Dad distributing his weight.

I wasn't so dainty.

This hole wasn't here before we walked around.

It was truly fascinating to see how water and time could ruin what used to be a beautiful house.

They used to be shelves...

After we went through the house it was time for me to take another nine-hour drive back to Midland. But taking the time to come see the old family was definitively worth it. That's all I got for this post. I hope everyone continues to have a great summer, and remember....

Stay safe!

Silver Lake State Park

Happy July 4th everyone! Given the date, I believe I owe y'all an American post, and what's more American than sand dunes,  jet skiing, and beaches? (probably a lot of things, shut up).

For my last most recent trip I went to Silver Lake in Mears, Michigan. Silver Lake is a fascinating state park that has forests, lakes, beachfront, and sand dunes all wrapped up in a small region in west Michigan. To get introduced to the area, I started by taking a Mac Woods Dune Rides tour. Our ride was a bit special because we got to take one of the original red cars from the 70's.

My Ride

The tour began by driving from the main road to a forested road that reminded me of West Virginia.


First we off-roaded it...

After we passed through a tunnel of trees, the scenery changed dramatically and before I knew it we were in the middle of barren sand dunes.

Suddenly, dunes!

The Silver Lake sand dunes are the largest alive sand dunes in the western hemisphere. What separates "alive" dunes from "dead" ones is that alive sand dunes do not have deep plant roots in the dunes. Therefore, the dunes are much more mobile than dead dunes, which resist movement due to the entrenched plant roots.

One side effect of this is that the dunes can quickly move and gobble up surrounding environments. For instance, the sand dunes here blew over a forest, and now the only remnants are the remaining sand-blasted tree trunks and roots. I thought the image was pretty chilling (especially if you're a tree), which prompted me to snap the picturesque image below.

New desktop background anyone?

Next our tour guide drove us next to the beach of lake Michigan, which was unnaturally still. No waves to be seen here.

Driving next to Michigan Lake

At the lake, our guide let us off and we walked around the beachfront for a while.

Pit Stop

One fun feature of this rest stop was the greater-than-life Mac Woods beach chair. I used to think everything was bigger in Texas, but now...

I guess Michigan has big things too?

After gathering back in the truck, we saw the live sand dunes swallowing yet another forest. If I was one of those trees, I'd be sapping my trunk.

Forest being swallowed by dunes

For the last part of the tour we drove by the city's namesake, Silver Lake. The lake is pretty fascinating since one half of it is surrounded by forests & homes, while the other half is surrounded by sand dunes.

Driving by Silver Lake

At the end of our tour our guide told us how to see the town lighthouse, so I decided that would be the natural place to go next. Besides, climbing a lighthouse has been something on my bucket list since high school, so this was too good to pass up.

Following the guide's instructions, I found the iconic little lighthouse.

Little Sable Point Lighthouse

Inside there was only room for one tiny metal staircase.

Lighthouse Stairs

At the top I finally had a glimpse of what a lighthouse bulb is supposed to look like. The bulb was actually less interesting than the glass casing around it, which featured particular ridges which focused and directed the light out towards the sea. This design made much more sense than what I expected (a bulb with a rotating mirror).

Light-bulb structure

I also enjoyed the old familiar tingling sensation of looking from a high place when I looked down the 130ft lighthouse.

Looking down

After getting down from the lighthouse, I was ready for some extreme sports, like jet skiing!

Wave Club Water Sport Rentals

I had a great time jet skiing on Silver Lake for an hour. At first I stumbled a lot, even falling off the jet ski after riding parallel to a boat's wake.

Silver Lake

After about thirty minutes though, I was comfortable riding the jet ski. First I managed to stand up (which considerably reduces bumpiness by the way), then I learned to open the throttle. Finally I rode the jet ski at full speed, a whopping 55 miles per hour.

At some point the renters waved at at me and said that I only had ten minutes left. What should I do to end the ride on a grand note? I decided that at 20 years old, my body could probably recover pretty quickly from any stunts that I pulled, so I decided to take advantage of that.

After I had the jet ski running at full speed (55 mph), I decided to fling myself off the jet ski sideways.

First the right side of my body hit the water. This caused me to bounce off the surface like a skipping stone. At 55 mph, water felt a lot more like a solid than a liquid. The force of the impact barrel-rolled me over and when the left side of my body hit the water I thankfully submerged. Once I finally got my head above water and swam to my jet ski, I returned back to shore.

Post-festivities

But I wasn't done with the day yet! The most extreme bit was yet to come. After slamming my body mercilessly into the water, I decided it was time to ride a sand-dune buggy.

Let's Buggy

The first thing I noticed when going out dune buggying was how ridiculously bumpy the ride was. The next thing I noticed was how different the sand looked on the buggy-only side of the dunes versus the people-only side.

Notice the sand paterns

Driving around I also witnessed another forested massacre caused by the live dune menace.

Dead Forest

Talking to other dune-buggy riders, I learned that there were even homes that had to pay upwards of $30,000 to keep the sand from burying their houses. Those sands were merciless!

These dunes are on the move.

The central attraction of the dunes though was Test Hill, a giant dune where cars would drive up at full throttle or else be doomed to stall halfway and be forced to turn around.

Test Hill

After riding around and getting sufficiently comfortable with my little quad (the type of dune buggy I was riding), I went as fast as I could up the hill, and made it!

Top of Test Hill

Thus concludes my Silver Lake adventures. After ridinging around I drove back to Midland and rested my beat up body as much as possible in preparation for the next work day. Until next time!
