Paul KingNARRATOR
The two equations really mean the same thing.
Paul KingNARRATOR
As many persons who use ordinary logarithms, which are calculated to base ten instead of base epsilon, are unfamiliar with the natural logarithms, it may be worthwhile to say a word about them.
Paul KingNARRATOR
The ordinary rule that adding logarithms gives logarithms of the product still holds good, or log base epsilon of a plus log base epsilon of b equals log base epsilon of a times b.
Paul KingNARRATOR
Also, the rule of powers holds good, n multiplied the, by the log base epsilon of a equals log base epsilon of a to the power n.
Paul KingNARRATOR
One can change the natural logarithm to the ordinary logarithm simply by multiplying it by point four three four three, or log base ten of x equals point four three four three log base epsilon of x.
Paul KingNARRATOR
And conversely, log base epsilon of x equals two point three o two six multiplied by log base ten of x.
Paul KingNARRATOR
A useful table of Napierian logarithms, also called natural logarithms or hyperbolic logarithms.
Paul KingNARRATOR
Natural log of one, zero.
JeremyHOST
[laughs] You're trying to code a, code name-
ChrisHOST
Or what? Or L- LN, I mean.
JeremyHOST
Ha.
JeremyHOST
Trying to code name and release where-
JeremyHOST
... he's from.
ChrisHOST
Yeah.
ChrisHOST
Yeah, LN, yeah.
ChrisHOST
LN is what I meant, not LB or whatever.
Don SullivanHOST
So before we get into some of the listings of different supervolcanoes around the Earth, as well as Yellowstone, let's talk about the Volcanic Explosivity Index.
Don SullivanHOST
It's a logarithmic scale, which means it's based on the natural logarithm, uh, E-based, or LN is the symbol in mathematics, or log base E as opposed to log base 10.
Don SullivanHOST
Uh, it's a zero to eight, which is used to measure the size and explosivity or explosiveness of any volcanic eruptions.
Don SullivanHOST
A guy named Chris Newhall gets credit, along with Steven Self, for actually coming up with this in the early 1980s, this idea of how to, uh, measure this explosivity, uh, based on the, uh, height of the explosion, the duration, um, the, um, the volume of rock ejected and, um, um, all of the materials.
Bishop B HennPANELIST
Yeah, man, blame Lennox for sure, man.
Bishop B HennPANELIST
His dad was trying to teach him players that went to LN.
MookPANELIST
Yes.
Bishop B HennPANELIST
You come into basketball and don't know who they are, bro.
Bishop B HennPANELIST
I just wanted to make it clear.
MookPANELIST
I'll be making a phone call.
Bishop B HennPANELIST
There's no LN players that was better than Pike players at that time besides Greg, Odin, and Mike.
MookPANELIST
Mm.
