And sound too!

from Spherical Cow Hosted by Olivia and Naina

Welcome back, Spherical Cow Moonions! This week we are continuing our discussion about the history of the universe and once again talking about 380,000 years after the Big Bang. We will be discussing the formation of sound waves in the early universe and how studying the imprint of these acoustic oscillations of the Cosmic Microwave Background map can tell us lots of fascinating information about our universe! Please see some additions/amendments to our discussion below: 13:42 - Sorry! I meant to say that you can do some calculations and see if they agree with your observations (i.e your measurements of the size of the ‘spots’ on the cosmic microwave background map). https://www.esa.int/ESA_Multimedia/Images/2013/03/Planck_Power_Spectrum - This is a link to the CMB Power Spectrum graph we discussed in our episode - the measurements were taken by the Planck Satellite To view our sources please see our website - https://www.podpage.com/spherical-cow/ N.B. This episode was recorded virtually so the audio quality might be different to normal and we are sorry about the noisy background in some places!

THE DFD (Dairy Farmer’s Digest) Podcast Keith Schweitzer Here we want to discuss all thing dairy farming. From calf to cow and everything in between. Each episode we will interview a new specialist, to bring information in their specific field. The Cows Are Mad BBC Radio 4 The Covid-19 pandemic has been one of the weirdest things any of us has lived through. But there was another sickness that once stalked the nation and turned things very strange for a while. In the 1990s Britain was hit by an epidemic of a fatal neurological disease in cows that also killed 178 humans. Science was split between government assurances of safety and dissidents warning of disaster. Trust in officials took a battering. Facts became blurred. And the grisly truth about our global industrialised meat industry was revealed. 30 years on, scientists and activists are still searching for answers to two big questions - where did mad cow disease originally come from and how did humans get infected? This crazy tale of cannibal cows, competing origin theories, and scientific dead ends lives on as the madness continues to spread.
