The Sounds of the Universe - Professor Carolin Crawford
Ανέβηκε στις 15 Δεκ 2011
In
space no-one can hear you scream... but it is still a noisy Universe.
We are familiar with the many stunning images of space, but these are
only part of the whole human experience. This lecture takes a new
approach to appreciating the Universe, through the vehicle of sound.
Once we understand how sound is propagated, we can look at the how and
where it can exist in space. We examine how sound can be a diagnostic of
cosmic phenomena (such as the song of the Sun and distant stars), the
way it can carry energy across vast volumes of space (away from a black
hole humming in B♭), how it can be a useful way to illustrate processes
in astronomy (such as the rapid spin of pulsars, and other more local
radio emissions) and how it is ultimately responsible for the growth of
all structure we see today in the cosmos.
The transcript and downloadable versions of the lecture are available from the Gresham College website:

continues today with all of our five or so public lectures a week being
