Los Alamos National Laboratory is a leader in safely performing radiological work. Our national security mission requires that we meet the highest standards of radiation protection for the health of our workers, the public, and the environment. To ensure worker and public safety, Radiological Control Technicians perform measurements of radiological conditions and levels around radioactive materials or radiation-generating equipment. Always in high demand, RCTs are a pivotal part of any facility…
Reinforcement learning is particularly useful in situations where we want to train AIs to have certain skills we don’t fully understand ourselves. Unlike some of the techniques we’ve discussed so far, reinforcement learning generally only looks at how an AI performs a task AFTER it has completed it. And when an AI completes that task figuring out when and how to reward an AI, called credit assignment, is one of the hardest parts of reinforcement learning. So today, we’re going to explore these…

The RGB Time Fountain is water fountain that utilises the stroboscopic effect to create illusions of the water drops levitating or even flowing upwards. Using precisely timed and synchronised red, green and blue strobe lights allows many beautiful and mesmerising illusions to be created.
The beating heart of the fountain is the diaphragm pump that produces…

Students use their knowledge about how healthy heart valves function to design, construct and implant prototype replacement mitral valves for hypothetical patients' hearts. Building on what they learned in the associated lesson about artificial heart valves, combined with the testing and scoring of their prototype heart valve designs in this activity, students discover the pros and cons of different types of artificial heart valves based on materials, surgery requirements, and lifespan.
