  • Audio quality is everything to a podcast

    While the information is good, one would think that a physics podcast would pay attention more to the audio quality to convey the message. There are many times that critical information is garbled.

Talking Points

Recent interactions between the hosts and their guests.

Asteroid deflection: why we need to get it right the first time
Q: Can you explain how we could unintentionally put an asteroid on a trajectory back to Earth when trying to deflect it?
Deflecting an asteroid incorrectly, such as through a gravitational keyhole, could return it to Earth, triggering a future impact.
Asteroid deflection: why we need to get it right the first time
Q: Could we deflect a large object if detected before it impacts Earth?
There are effective methods like kinetic impact; however, the feasibility depends on the size of the asteroid and the time available before impact.
Asteroid deflection: why we need to get it right the first time
Q: What sort of threat is posed to Earth from asteroids?
Currently, no known asteroids pose a significant risk of impacting Earth over the next 100 years, but many unknowns exist that could potentially cause dire consequences.
Quantum Systems Accelerator focuses on technologies for computing
Q: What is the QSA doing towards building a skilled quantum workforce?
The QSA engages high school and community college students through hands-on programs, training educators, and establishing pathways for careers in the quantum industry.
Quantum Systems Accelerator focuses on technologies for computing
Q: What are some of the challenges of creating new quantum technologies, and how is the QSA helping to overcome them?
