(video: https://youtu.be/RPWMAqPhv6w)
UNFORTUNATELY the video did not advance the slides (talk about errors to
correct, though the audience saw the slides advance). I tried to record the
audio with the slides advancing at home, but it garbled the audio! So, here's
how you correct the error. Play the video from https://youtu.be/RPWMAqPhv6w
but ONLY play it for the audio, ignore the video! Start that at 40 seconds.
Now play the video from
https://youtu.be/P6I0Z9CFPcQ BUT start that at 20 seconds and have that on
mute! Thus you listen to the audio from the first to the video of the second.
