I knew you'd back me up, Phro! Stake burning in England. What a joyous occasion.

Re: Add 13 more and post it forever.

post 128
x       13
-----------
       3 8 4
    1 2 8  -
=======
     1   6  6  4

So
1638 + 13 = 1651
And
1651 + 13 = 1664

1794

The sum of the two inner digits less the difference between the two outer digits = 13.

1781...ties in well with your new avatar, Bobby!

Uranium was named in 1789 after the planet Uranus, which had been discovered some years before, in 1781, by William Herschel. Uranium was used in the "Little Boy": the first nuclear bomb used in warfare (see piccy). c.f. Bobby's obliteration bomb avatar.

1833 = MDCCCXXXIII

Re: Add 13 more and post it forever.

Why good for you, Bobby? Was that the celebration of 100 years before you were born? Did someone know something?

It was doubly good for me because I wasn't in England then and missed the cholera outbreak there, and also because I wasn't born yet and that made sure I missed it.

1859

I would never have gone on a Ferris wheel ride if it wasn't for George Washington Gale Ferris, Jr., the inventor of the Ferris wheel, who was born that year.

Some of the people in here think that I might have been around at that time.

1872 - the Mary Celeste mystery.

Not all? There's some doubt about your D.O.B., then?

1885

The first successful appendectomy is performed by Dr. William W. Grant on Mary Gartside. (Wikipedia). And the others?

1911

1911-(the reverse of 1911)-(the 180 degree sideways rotation of 1911)+(the reverse of the 180 degree sideways rotation of 1911) = (the reverse of the 180 degree sideways rotation of (the sum of the digits of the 4 resolved elements of the left-hand side of the equation plus the sum of the digits of the degrees on the left-hand side of the equation)) × 13.

Re: Add 13 more and post it forever.

I'm sure you were, now you're reminding me of the show New Amsterdam. It says bobby was born in 1638 in post #126.

I'm not liking this anymore, it's getting closer to nowadays...
