Everything that has to do with 3d printing and 3d printers. From the high end to the open source Reprap A Freemarket Anarchist..

I need some counseling. I do not know what to do when it comes to employment. My options here in Kitsap are not all that great, yet I am scared that if I move even if I had the means I'd still end up like I am now with bad employment options.  

The crazy roommate just threatened my dog and said out loud he has the right to commit murder. Not self defense, but murder. Khoc won't do a bloody thing about him.

I being Autistic makes dating a living hell. That just depresses me. When I see none-Autistic people able to quickly find a new relationship. I can’t flirt to save my life. I wouldnt know if the gal ,likes me to save my life. It so frustrating. All I want is a long term relationship. Thats it. 

Using ultrafast time-resolved pump detection technology, researchers led by Prof. Sheng Zhigao from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences have realized the gigahertz (GHz) frequency birefringence modulation induced by ultrafast coherent phonons in strontium titanate (SrTiO3) crystals.
According to the researchers, the operating frequency was found to be much higher than the cutoff frequency of the commercially available photoelastic modulators.
The study was published in Advanced Science.
A special material with birefringence can shape light. The photoelastic modulator based on birefringence modulation technology is one of the core components of modern optical technology. At present, most photoelastic modulators use the mechanical stress provided by piezoelectric materials to drive photoelastic crystals to achieve birefringence modulation, and their operating frequency is limited by the resonant frequency of photoelastic/piezoelectric crystals, which is generally in the order of kilohertz (kHz). Therefore, there is an urgent need to develop birefringent materials and modulation techniques with GHz operating frequency.
