Why Thermodynamics Matter to Particle Physicists - with Suzie Sheehy
Δημοσιεύτηκε στις 9 Δεκ 2016
Why do we need the first law of thermodynamics? What use is it? Dr Suzie Sheehy explains what it means to a particle physicist.
Day 9 of our advent calendar. Watch all the videos here: http://www.rigb.org/christmas-lecture...
The
four laws of thermodynamics touch almost every type of science, and
impact on research and understanding in different ways. In this
animation, particle accelerator physicist Suzie Sheehydiscusses why the
first law of thermodynamics is so important to particle physics.
To
describe the motion of almost any system, from a car on a road to
particles in an accelerator, you have to be able to trust that certain
quantities are conserved. From the simple rule that energy is conserved,
you can deduct incredible information.
In a particle
accelerator, particles are collided with each other, or with other
matter. The result is a spray of the component particles, but some of
these can’t be detected by modern machines. For example, neutrinos have
almost no mass and as such are almost impossible to directly detect. But
because energy is always conserved, the physicists can tell what
properties they haven’t detected by calculating the difference between
the initial input and the output they find.
The first law of thermodynamics gives a predictive power that lets scientists understand the world.

The
2016 advent calendar explores the four laws of thermodynamics with a
new short film each day, with explosive demonstrations, unique
animations, and even a musical number. Open the calendar at http://www.rigb.org/christmas-lecture...
