Skim a Pond


Last Friday I went skiing at Arapahoe Basin. Yes, there's still snow up there - but the warm weather is melting it, resulting in conditions known as Spring skiing. The water from the melted snow collects in valleys and trenches, forming ponds excellent for skimming.

Skimming is skiing on water. To skim a pond, the upward force from the skis must exceed the skier's weight, and it must continue to exceed his weight until the skier gets across the pond. The force is determined by the skier's forward velocity, the surface area of the bottom of his skis, and the angle of his skis.

On Friday when I visited Arapahoe Basin, I skimmed a few ponds. It's lots of fun, as long as you don't slow down too much halfway through the pond. Here's a video from my trip:

2014 in Photos

The year of 2014 is over; the year of 2015 has begun. Over the past year, I took a lot of pictures - more than 1200 photos of clouds, bugs, plants, rocks, and more. I deleted most of the low-quality and repetitive photos. Then, I selected 20 of the remaining photos which I thought were the most interesting or significant. In this post, I'll include those photos, in chronological order. Spring 1. Cold Hummingbird I took this photo after a late snowstorm in Spring. In the days leading up to the storm, it was warm and sunny and the fields were green, so the snow came rather unexpectedly. During the storm, one of the hummingbirds at our feeder was covered in ice and could barely fly. This hummingbird was more fortunate, but unlucky nevertheless. 2. Green Landscape I took this photo on the side of a biking trail. I didn't edit or crop the photo - this is how it looked. 3. Indian Paintbrush The Indian Paintbrush is an unusual flower. What appear to be flower petals are actually brigh...

Nature Wallpaper

I collected 12 of the highest-resolution, best-quality photographs of nature I've taken over the past few years, cropped them to highlight the important parts, and then applied JPEG compression. Now I'm releasing them for my blog readers to enjoy as a desktop background. To download as a .zip file, click here . Note that the photos shown in this post are low-resolution previews.

Major Change of Ideas

Edit: April Fool's. The article completely fails to answer for the benefits of math and science (including medicine and natural disaster prediction). It grossly exaggerates the negative aspects of math and science. Incidentally, math and science have made a large positive difference in my life. Good morning, everybody! I decided to write a blog post to say that I will be completely changing the way I view knowledge and the purpose of life. Photo credit: my sister Basically, "higher" knowledge (including logic, science, mathematics, etc.) is completely useless. There is no point in learning these subjects, which is why I have dropped all my college classes and will not be going to school today. Instead, we should go to the fields, with a shovel and a rake, and grow crops. I will therefore end my blog and begin life as a worker at a ranch in Wyoming. Why this sudden change, you might ask? A few days after my last post (which nobody seemed to read), I came upon a realizatio...
