He sounds like he gets out of bed in the morning and is absolutely thrilled he gets to do more math, every single morning
-
"Give me a prime" "2^31 - 1" Baller move. Brady should do that the next time Matt Parker asks for a number
-
Neil Sloane is always worth my time.
-
Seeing Neil Sloane enjoy his sequences (and talk about them) is always a pleasure. Please do more interviews with him in the future!
-
He always seems like a child who has found something interesting to play with 😍

The largest prime that I know the digits of is Belphegor's Prime: 1 0000000000000 666 0000000000000 1 Thirteen zeros before and after the number of the beast, 31 digits (13 reversed) in all.

Just an FYI, CCS is pretty much just a waste of money, and has never been demonstrated to be effective at reducing CO2 emissions.
-
Great, now I can boast about knowing a 17000-digit prime by heart! Thanks

4:39 "I'm not finished. I have another segment." I don't know why, but I really enjoyed that. He loves and can talk about numbers all day.

I got curious and decided to try this - but with base-2 instead of base-10. And I think I found one! 01101110010111011110001001101010111100110111101111, which is 485398038695407, _is a prime_. And it contains the numbers from 0 (which might as well not be there) to 15.

"It's a story you can tell at parties." I'd love to go to a party where I get to hear Neil Sloane's stories!
-
He better live to a hundred or I'm gonna cry
-
I would love to hear more from this gentleman, he can be a narrator for some great shows
-
@numberphile hey! I saw this and thought, "what about concatenating increasing values to the left" i.e. 1,21,321,4321,54321, etc. Did a little bit of number crunching and the first one I found was at a starting value of 82. They exist! (I was able to speed up my search realizing that 2/3 of these are divisible by 3 and skipping testing those.) Maybe look for the next one and make a video on it? Prime related videos are always a hit. :) Anyway.... Loved this video! It inspired the little search I just did.

Prime numbers and numberphile videos about them , never get old
-
The professor has such a beautiful voice.
-
I'm intrigued by the sequences both so important and so hard to evaluate that they have the privilege to be included in the OEIS with only one entry. Tell us more about that please !
-
I would like to note that if the step between each number is 2 instead of 1 (so 135... instead of 123...) the first prime is 13, but the first interesting one is 135791113151719
-
Now I'd really like to know which sequences in the OEIS contain a single term
