As a PhD student in Aerospace Engineering, he is focused on developing new aerospace exploration technologies that can inspire and improve the world. During his undergraduate years, he worked in a research lab supporting NASA’s Quiet Supersonic Technology (QUESST) mission, measuring rocket launch acoustics, and reentry sonic booms of SpaceX’s Falcon 9. He also interned at NASA Langley Research Center, where he used machine learning and sonic boom prediction software to help prepare for the X-59’s first flights.

Now, at Stanford, he is entering the field of computational aerospace engineering. He aims to develop computational methods that will aid in designing the next generation of rockets, planes, spacecraft, and hypersonic systems.

He also strives to support the next generation of aerospace engineers. In an industry that can seem daunting and overwhelming, he is dedicated to providing knowledge, tools, and connections to those who need them.

 Dr. Ed Garnero is a professor in the School of Earth and Space Exploration at  @arizonastateuniversity . He is celebrated for his work in Seismology, his  @TEDx Talk... and his scientific approach to building high-end custom bass guitars? 

Dr. Edward Garnero specializes in geophysics and seismology, but his journey has shifted to another passion, Lutherie. His "day job," as he calls it, is focused on studying the Earth's interior, from the uppermost mantle down to the core. One of his key contributions includes the study of massive structures deep in the Earth, such as "blobs" found at the core-mantle boundary, which are believed to be chemically distinct from the surrounding material and play a role in volcanic processes. 

As a Luthier, Dr. Garnero now implements his decades of scientific research into brilliant instruments. Garnero integrates unique design features like resonance chambers into his instruments, which reduce weight and enhance the tonal qualities of the guitars. He enjoys experimenting with tonal qualities and sonic vibrations, inspired by his scientific background and love of music. His basses are known for their custom craftsmanship, often incorporating rare woods and hardware, and have a distinct aesthetic rooted in both practicality and artistic expression.

 Dj and Lauren Fotsch have worked with the likes of  @Apple ,  @Netflix ,  @Samsung , and  @humane . 

We covered a variety of topics from marketing to family life, forensic failure analysis to artificial intelligence. The topic of Ai really stuck with us... why do we fear Ai? Could we think of it as a benevolent "Assistive Intelligence" as opposed to a malevolent "Artificial Intelligence? ...and whats the difference? 

Here's what we came up with... 

Assistive intelligence: AI systems specifically designed to augment human abilities, providing support in tasks like decision-making, problem-solving, or daily activities without replacing human involvement. It is often collaborative, working alongside humans to enhance productivity and improve accessibility. 

Artificial intelligence: a broader range of technologies focused on replicating human-like cognitive functions such as learning, reasoning, and self-improvement, potentially functioning independently of human input. While assistive intelligence enhances human capability, general AI aims at creating autonomous systems that can perform tasks without human assistance.
