    Wrong, but Useful: Episode 76b

    What's this? Didn't we have a WBU last week? We did indeed. Only we cut out a section of our conversation with @dr_teeluck about APR to keep the episode length (somewhat) reasonable. Here it is as a special bonus episode for your enjoyment.

Ace.

I can’t improve on the previous reviews here. Colin and Dave provide lovely and interesting listening. Serious maths presented without off-putting seriousness. Hilarity delivered in deadpan … except for when one breaks down in a giggle (I could listen for those moments alone). Mathematics presented by mathematicians incredibly accessibly; intermixed with stories from their own lives. “They’re just these guys, you know?"

All the stars

If you enjoy doing maths, hearing discussions about maths, or just listening to intelligent conversation, then this is a podcast for you. Be it your first maths-related foray or an addition to a line of 'other' podcasts you’re subscribed to, this is well worth your time.
Covering a wide variety of topics - governed by whatever has crossed the 2 hosts' minds in the past month. And if ~1 hour isn’t enough, then at the end there's some homework to take away and work on before next time :)
Wrong, but Useful – one of my favourite podcasts, always jumping to the top of my must-listen-to pile.

@DrewBk ,

Splendid

Unassuming, gentle and informative chat on mathematics whether it is in the news or just plain interesting tidbits. A pleasure to listen to.
