Diamonds Lead to Ultra-High Pressure Situations
Sunday, July 24, 2016
Trying to find the perfect diamond has always been stressful, especially in a high-pressure environment. However, recent experimental results take the relationship between diamonds and pressure to a whole new level. An ultra-high level, in fact, that cou... more

Winding Light Takes New Paths
Saturday, July 23, 2016
Light travels in a straight line. If that ceased to be the case, reflections, shadows, and really the whole world would make a lot less sense. During the past several years, however, scientists have created beams of light that curve as they travel, calle... more

Experimental Results Hint at Fifth Fundamental Force
Friday, July 22, 2016
Last week, we reported on a new theory by Dr. Jonathan Feng and collaborators, slated to appear in Physical Review Letters, which postulated a fifth fundamental force of nature. Exciting as this work is, our piece contained some errors and gave altogethe... more

Microwave Technology Heats Up
Wednesday, July 20, 2016
Microwaves provide more than just a quick meal. The transmission of information via microwaves (the type of light, not the appliance) is fundamental to technologies such as Bluetooth communication, mobile phone networks, satellite televisions, radar, and... more

Did Rembrandt "Cheat"? Optics Paper Weighs in on Art History Debate
Thursday, July 14, 2016
Works of art by masters like Rembrandt may have harnessed the power of light to create awe-inspiring, realistic paintings. This being Physics Buzz, artistic techniques are not really our specialty. However, it’s worth a look at the way that the scientifi... more

Ask a Physicist: Time Warp Brain Teaser
Tuesday, July 12, 2016
Bill, from the US, wants to know:Would a satellite with a perfectly circular orbit around the center of a circle experience time dilation relative to an observer at the center of the circle? What if the observer were spinning to always be looking at the ... more

Putting a New Spin on Sound Waves
Monday, July 11, 2016
It's already possible to do some really extraordinary things with sound waves, like levitating small particles and manipulating them in-air (useful for caustic chemistry reactions) but we're about to see another tool added to the sonic utility ... more
