WHILE the crystalline composition of dental calculus in man is well elucidated, very little is known about such calculus in animals. We have had the opportunity of comparing the results of X-ray ...

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...

X-ray diffraction (XRD) is a powerful non-destructive analytical technique used to evaluate crystalline materials and determine their structural properties. As one of the most widely used ...

Corrected: This story has been updated to reflect Ralph Pantozzi’s full statement. Corrected: A previous version of this story misstated the location of Kent Place School. It is located in Summit, N.J ...

Difference between Interference and Diffraction: This article covers an important topic from Class 12 Physics. As we all know, Physics is one of the toughest subjects in Class 12. With the vast amount ...

I learned in October 2022’s Breakthrough that the spikes of stars in high-power photos are called diffraction spikes. Why do they appear as two crosses at 45 degrees to each other? The diffraction ...

This teacher believes that “deprioritizing abstract math like calculus in favor of practical math, with a focus on statistical literacy, reduces barriers to entry and will help increase diversity in ...

Abstract: The diffraction coefficient of the geometrical theory of diffraction is expressed in terms of contour integrals that are of the same form. A series of approximations are made for the ...

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 ...

Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometer precision. In the future this method could be used, for instance, to make optical components for ...
