Excellent lecture!

[@sardar_gurjot]

I don't why I am even watching it but I am. it's pure philosophy.

We can't write about 10^24 lines on that 1s band; however, if we imagine that we cut the band(s) in half once a second for 80 seconds then we would end up with 1.21*10^24 partitions. My math work: 10^24 = 2^x ln(10^24) = ln(2^x) 24*ln(10) = x*ln(2) x = (24*ln(10))/ln(2) x ≈ 79.726 2^79.726 ≈ 10^24

wait they dont teach this in high school in US?

[@Lwyte17]

It depends on the high school.
