Georgia Students to Speak with NASA Astronaut on the International Space Station

Students at the Fayette County Public Library in Fayetteville, Georgia, will speak with a NASA astronaut living and working aboard the International Space Station at 11:45 a.m. EDT on Monday, June 19. The 20-minute, Earth-to-space call will air live on NASA Television and the agency’s website.

No Universe without Big Bang

According to Einstein's theory of relativity, the curvature of spacetime was infinite at the big bang. In fact, at this point all mathematical tools fail, and the theory breaks down. However, there remained the notion that perhaps the beginning of the universe could be treated in a simpler manner, and that the infinities of the big bang might be avoided. This has indeed been the hope expressed since the 1980s by the well-known cosmologists James Hartle and Stephen Hawking with their "no-boundary proposal", and by Alexander Vilenkin with his "tunnelling proposal".

Smart materials used in ultrasound behave similar to water

Researchers have provided new insight into piezoelectrics materials, a smart material used in ultrasound technology. While forming the most thorough model to date of how these materials work, they found striking similarities with the behavior of water. A more complete understanding of why these materials behave the way they do can unlock new materials design, leading to higher quality piezoelectrics that may revolutionize smart material applications.
