But what exactly do those sigma levels mean? Why do theoretical physicists require much higher sigma levels that medical scientists? And how do sigma levels relate to so-called <em>p-values</em>?</p><p><a href='https://plus.maths.org/content/sites/plus.maths.org/files/podcast/spiegelhalter.mp3'>Listen to our interview with David Spiegelhalter</a></p><p><a href="https://plus.maths.org/content/what-are-sigma-levels" target="_blank">read more</a></p> https://plus.maths.org/content/what-are-sigma-levels#comments p-value probability risk sigma level uncertainty University of Cambridge Wed, 16 Dec 2015 14:02:41 +0000 mf344 6498 at https://plus.maths.org/content What is a black hole – physically? https://plus.maths.org/content/what-black-hole-physically <div class="rightimage" style="max-width: 350px;"><img src="https://plus.maths.org/content/sites/plus.maths.org/files/articles/2015/Tong/blackhole.jpg" alt="Curved space-time" width="350" height="222" /> <p>An artist's impression of a black hole.
