38:11 Si vs Ge vs Diamond; 40:35 heavier elements have smaller band gaps

I missed you professor can't wait for more

I was with you all the way to London...

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?
