Jet engines need cutting-edge materials that are strong, light and can withstand extreme heat. GE is developing a material that can handle high temperatures like ceramics can and is also as tough as metal. Here, a projectile fired at a sample of advanced ceramic composite tests the material’s ability to endure the strike.

Pappubahry has interpreted this kind of image as the stars emerging from behind Saturn (top left section of the image). Here, successive images in a sequence are superimposed, showing each star as a trail. Where a star emerges from behind Saturn (particularly at far left and far right), note how the light is at first dimmed and refracted by Saturn’s atmosphere.

“Reading a chapter from Warren Buffett’s Tap Dancing to Work the other day, I was surprised to find myself chuckling out loud. Now this guy is kind of funny, I thought to myself as I turned the page and grabbed another Danish. This guy is kind of making me laugh. And those thoughts that I had quietly, in my head, to myself, made me realize just how rarely I do have those thoughts in my head. And that thought led me to another thought, which was: why is that? Why, on the whole, are men just not that funny?”
Love her. Now I have to watch the office again.
