197

[Guyon]

197 is a prime number and a twin prime with 199. The third of a prime quadruplet, 197 sets a record low for the Mertens function, -7. It is also a Chen prime, and an Eisenstein prime with no imaginary part.

There are two different ways of expressing 197 as a sum of consecutive primes: as the sum of the first twelve primes and also the sum of seven consecutive primes (17 + 19 + 23 + 29 + 31 + 37 + 41).

197 is a centered heptagonal number.

197 is a Keith number in base 10, because it recurs in a tribonacci-like sequence started from its digits: 1, 9, 7, 17, 33, 57, 107, 197 ...

i dont know what the heck you were talking about, but cool fbm!!

Brrrr, looks cold. Southern Arizona is in the triple digits right now. BTW, did you sand the scales? Nice chunk-o-steel!

You have snow right now??? Or is that an old picture?

Er...purdy knife too.

Neither do I, but I bet Old Physics does!

If ya'll think it's snowing in Tennessee right now, I've got some land in East Tennessee I'd like to sell you. Don't mind the National Forest signs. This land is a secret government package and is great hunting land.

If 199 is twin to 197, then I have that Beauty's ground dwelling mini-me coming.
Sweet blade though, I keep wondering if I could swing an FBMLE.

My FBMLE is 40+6 or 50-4 or 23+23.

And I didn't even need wikepedia for that.

Thanks for the great pic:thumbup:

I should have listened more in math class

I agree. But it's a very nice pic of an even nicer blade:thumbup:

If that knife was #198, would that throw your whole "prime" world into chaos?

Icecaps would melt. Floodwaters would rise. Earthquakes would rumble.

Hoards of locusts would descend.

Even worse, Amy-0 would stop BRINGING IT.

I shudder to think of it.

Aaah, the mystery of numbers! You're certainly reaching deep into number theoretics with that quote! I won't bore you with the details, which I'm sure Wikipedia will give anyone who cares. They refer to interesting relationships between prime numbers and to things like Merten's Conjecture (disproved in my lifetime -- but linked to the weaker and more fascinating Riemann Hypothesis).

But, you don't need to be an obsessed mathematician to realize...#197 is clearly an important number!

Hey, that was my point! Guess it takes a physicist to put it in layman's terms.

My FBMLE is the Answer to the ultimate question of life, the universe, and everything.

Now THAT'S a conspiracy!!

Dangit. He's right. 42 trumps 197 every time.

Not really. 197 breaks down to 8 which is infinite. Much more powerful than 1/3 of evil, 6.
