I like this pair of videos. I remember someone was lamenting the prevalence of the claim that nothing is ever really true. They claimed that people who said such things were ignorant of mathematics. At the time, I had no response, but my understanding of mathematics has always been that it's a family of tools for reasoning towards things that are necessarily true *given certain premises*, and without that last bit, claims about truth are, at best, incomplete. Grant states essentially that succinctly in the second video, which is nice to hear from someone who is way more mathematically adept than me.
