The reproducibility of published experimental results has recently attracted attention in many different scientific fields. The lack of availability of original primary scientific data represents a ...

Synchrotron beamlines and their instruments are built to harness the photon beam power of synchrotron radiation (SR), which has special properties -- ideally suited to providing detailed and accurate ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

Mount the laser and diffraction plate on opposite ends of the rail, making sure the laser is pointed away from people. Plug in the laser and aim it at the desired pattern, maximizing the intensity of ...

Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies. (Nanowerk News) Physics is full of pesky ...

Physicists often find thrifty, ingenious ways to reuse equipment and resources. What do you do with 800 square feet of scintillator from an old physics experiment? Cut it up and give it to high ...

Non-ambient diffraction is a powerful tool for identifying the effects of temperature, humidity, pressure, or atmosphere on a sample. Materials exposed to non-ambient environments tend to have ...

What is the most beautiful experiment in physics? Robert P Crease invites your suggestions Small wonder: this STM image of an oval-shaped array of iron atoms on a copper surface is a real experimental ...
