Picosecond resolution photoelectron emission lifetime detection system
This paper describes a new photoelectron emission lifetime detection system. It is based on a recently developed Radio Frequency Timing technique of keV electrons and a 40 MHz, ultrafast pulsed laser. The photoelectron emission lifetimes from gold, monolayer MoS$_2$ and monolayer graphene were measured. As expected, we do not observe delayed electrons from gold, and the time distribution of the produced photoelectrons represents the time resolution of the device, which is $\sim$12~ps. From the …

Fired over Gaza? Dr. Rupa Marya Sues UCSF, Says She Was Targeted for Speaking Up for Palestine
We speak with Dr. Rupa Marya, a physician, activist, author and composer, who this week filed two free speech complaints against her former employer, the University of California, San Francisco. The school fired her last month after a lengthy suspension over her criticism of Israel’s war on Gaza and its impact on healthcare in the Palestinian territory. “I didn’t expect that my career-ending move would be to say 'stop bombing hospitals,' for expressing support for Palestinian liberation a…

"Hard to believe, but it has been already almost 20 years since the days when Apple plastered the halls of its Worldwide Developer Conference (WWDC) with huge posters proclaiming “Redmond, start your photocopiers” or “Mac OS X Leopard: Hasta la vista, Vista”. The decade of the 2000s, coinciding with Steve Ballmer’s tenure as CEO, is widely perceived as a lost one for Microsoft, and one of the most visible signs of that decline was, without a doubt, the “Longhorn” saga."

Hard to believe as it is, it has been already almost 20 years since the days when Apple plastered the halls of its Worldwide Developer Conference (WWDC) with huge posters proclaiming "Redmond, start your photocopiers" or "Mac OS X Leopard: Hasta la vista, Vista".

". . . pulling out a keffiyeh and shouting, “Free Palestine!” But his depraved actions, like theirs, expose the lie of his lofty words. Neither Palestine nor Israel will ever truly be free until their societies are liberated from megalomaniacal men who perpetrate demonic acts in their name."

The D.C. Jewish Museum Shooting and a Dangerous Disguise for Anti-Semitism
The person charged with attacking an American Jewish gathering and killing two Israeli-embassy aides disingenuously invoked the Palestinian struggle as a pretext to harm Jews.
