People often try to visualize things like photons and subatomic particles, when it wouldn't be possible to do so. While they certainly exist, you can't bounce photons off of other photons or subatomic particles to see them. They don't have shape as we understand it.
Amazing!
How a young uneducated Michael Faraday became a world changing scientist and strove to help others be inspired the way that he had been himself.
And his detailed, intricately illustrated notebooks are going online shortly.

Wow, this sounds kind of exciting.
Steps towards creating a Thorium Nuclear Clock and using it to measure the Fine Structure Constant carefully enough to see if it is changing (there has been some evidence that it might not be truly constant). Which is a scary wild thought, actually.
I feel like there's a Doctor Who premise in here somewhere!
Here are some shots of last night's lunar eclipse captured by the Allan I Carswell Observatory crew!
Missed the lunar eclipse? Well you're in luck! We livestreamed it and you can watch here:

hey maths and physics nerds

Unlikely to ever be directly useful in practice, partly because the grating spacing and alignment is so touchy and the light modulator's resolution and speed would need to increase, partly because other methods are so effective.
Still very cool for the nerds!

Is ranch dressing a liquid or a solid? our @ScienceDesk asked, via @TheConversationUS's Curious Kids series (also good for curious adults). Turns out it’s something called soft matter, like cookie dough, toothpaste, and snot.

The ConversationIs ranch dressing a liquid or a solid? A physicist explainsA physicist explains that the short answer is both … and neither.
Today in History, March 14, 1879, Albert Einstein was born. In addition to being one of the most significant physicists of all time, he was also a pacifist. Yet his letter to President Roosevelt warning of the Nazi progress on atomic weapons research was arguably key to the U.S. implementation of the Manhatton Project, a decision he later lamented. In 1955, well after the Cold War and nuclear arms race had begun, he and ten other intellectuals and scientists, including other Nobel Prize laureates, like Bertrand Russell and Linus Pauling, wrote a manifesto warning of the dangers of nuclear weapons. Einstein also participated in the U.S. Civil Rights movement, calling racism America’s “worst disease.” Later in his life he began to support socialism, and he criticized the Bolsheviks for their barbarism. Einstein was also a Zionist, and supported Jews’ right to return to Palestine. However, he did not support a Jewish state, or an Arab state, to replace Mandatory Palestine. Rather, he wanted a free, bi-national Palestine in which Jews and Arabs shared sovereignty, living peacefully and equally with each other.
