Researchers at the George W. Woodruff School of Mechanical Engineering have developed a new approach to nanoscale 3D printing ...

What happens when a wave passes through some opening? It diffracts - or you like, you could say "bends". If the size of the opening is comparable to the wavelength of the wave, the bending can be ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

The nonrepeating Smith hat tile created twisting, pinwheel-like light patterns that ordinary quasicrystals do not produce. Its unusual effect comes from combining long-range order with a lack of ...

Stars in the new images from the James Webb Space Telescope look sharper than they did before. And I’m not just talking about the image quality, which is astounding. I’m talking about the fact that ...

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...

X-ray techniques have been used for decades by authorities to prevent crime and keep people safe. Perhaps their most well-known use is for the detection of dangerous and banned items or substances, ...
