ROHM's RPR-0730 Analog Compact Optical Sensor Capable of high-precision detection of fast-moving objects. Relationship Between Line Width and Speed RPR-0730 achieves high-speed and high-precision ...

Using ultra-fast laser pulses and special cameras, scientists have simulated an optical illusion that appears to defy Einstein's theory of special relativity. One consequence of special relativity is ...

A team of researchers at the University of Minnesota Twin Cities have been working on a way to move objects without any contact! They developed a way to manipulate objects using ultrasound waves.

For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical illusion called the Terrell-Penrose effect. When you purchase through links on ...
