DC Science Cafe at Busboys and Poets
Your fridge keeps your milk form spoiling and your freezer converts the water in your ice trays into ice cubes that make your summer drinks cold. If your fridge could keep getting colder, when it dipped to -109 degrees, the carbon dioxide inside of it would form into a frost of dry ice. At -362 F oxygen would freeze into solid oxygen ice. But what happens at temperatures colder than the most remote places in outer space? How could you cool something that cold? Join physicist Trey Porto of the Joint Quantum Institute as he answers these questions and more about the world of the ultra-cold. Find out how lasers can be used to produce the coldest temperatures in the universe, and how studying the world at these cryogenic temperatures can open pathways to next-generation GPS technology, atomic clocks that would not lose a second for 10 billion years, quantum computers, and new exotic states of matter. This event is free and open to the public.
