"Redefining Humanity's Place in the Universe: A Physicist's Perspective"

Theoretical physicist Matt Strassler discusses his new book, Waves in an Impossible Sea, which explores the connection between the fundamental laws of the universe and everyday experiences. He aims to break down the dichotomy between physics on Earth and astronomical observation, emphasizing that humans are not disconnected from the larger universe but are made from it. Strassler hopes to provide a path for readers to understand complex physics concepts and emphasizes the importance of ongoing research, particularly at the Large Hadron Collider, in unraveling the mysteries of the universe.

"The Nature of Time: A Philosophical Exploration"

In a podcast episode, physicist Frank Wilczek discusses the nature of time, its role in scientific progress, and its conceptual evolution from Newton to Einstein. He explains that time is what clocks measure, and delves into the implications of Einstein's theories of special and general relativity, which introduced a more flexible concept of time and led to groundbreaking insights into the nature of space-time. Wilczek also highlights the interconnectedness of time with various physical phenomena and the practical applications of precise timekeeping in systems like GPS.

"The Deadly Consequences of Jumping Through the Earth's Core"

Digging a hole straight through the Earth is impossible due to the molten and liquid layers, but in a hypothetical scenario, jumping into such a hole would result in death from various factors. The first would be the extreme temperature, with the deepest humans have ever drilled reaching 180°C (356°F) at just 12 kilometers down. The second would be the massive increase in pressure, as the air would become highly pressurized and compressed. Additionally, if the pressure gets too high, it would likely evacuate all the air from the surface, killing most life forms. Finally, if the hole is not aligned with the Earth's axis of rotation, the rotational acceleration would cause the person to drift into the walls at high speed, resulting in injury or death.
