Khan Academy

In this post, I'll tell you about a really cool new site I found: Khan Academy.

Khan Academy is basically a bunch of free tutorials for school subjects like mathematics, history, science, and just about anything else. And not only that, but they also have a special practice page that offers exercises, and when you complete enough of them you get points.

And here's one of my favorite things about it: they have a special section just for computer science, so I can write programs (mostly video games), and everybody else can see and play them. So far I've only written one program, but it's pretty good for my first (even though it's not finished yet). But one of the coolest things about that programming feature is that you can embed the program on a web page:

Super Ball

Another nice thing is the badges you get for accomplishing certain things. There are 6 types: meteorite, moon, earth, sun, black hole, and challenge. The easiest to get are the meteorites, and the hardest are the black holes (you don't even know how to get the black holes!). The challenge badges are just extra stuff. You can display up to 5 of your badges on your profile page for everybody else to see.

So check it all out - go to www.khanacademy.org! If you ever forget the link, just check my Links page.

    I was wondering what embed code you used to embed your program into your blog? I tried just copying the embed code from my program on Khan Academy but I don't think the new code is working for blogs. Thanks!

      I post KA programs on my blogs all the time.

      just click the "share" button and under all the social icons is some code for embedding, click highlight it, copy it and paste it in the HTML in your blog-post.

    I wrote a Khan Academy program that will generate some HTML to use for embedding here:

Which Hurts More?

212° F Let's play a little game. I'll list a bunch of possible actions. Each action will have 2 variations, (a) and (b). You choose either (a) or (b), depending on which would be safer (or less painful). Each of the questions will involve an oven hot enough to bake a cake (350° F), and a pot of boiling water (assume we're at sea level). So... would you rather: 1.     (a) Stick your hand in the oven     (b) Stick your hand in the boiling water   ... for a period of 10 seconds 2.     (a) Leave a fork in the oven     (b) Leave a fork in boiling water   ... for a period of 15 minutes. Then hold the fork tight with your bare hand. 3. Fill a jar to the top with cool tap water. Then:    (a) Place the jar in the oven    (b) Place the jar in the boiling water   ... for a specific, but unknown, period of time. Then remove the jar and put your hand in it. First see if you can figure these out yourself. They shouldn't be too...

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. If you have any questions about the wallpaper, please comment! New posts every month -  subscribe for free !
