Puzzle Description:

The letter "A" hosts a party with all the other letters. All have fun, laugh, dance and drink. But the letter "e"stands in a corner without speaking to anyone. The letter "g" comes over and says: Come on, integrate! And the letter "e" answers: Why? It is the same

I don't get it.

Even though I thought 2,1,10,1,2 was probably the intgration symbol I "guessed" backwards to see how far I would have to go before reaching a contradiction. It was about 6 more moves ahead. Anyone solve it without "guessing"?

Enjoyed the joke even if it is somwhat derivative.

Angle theta was sunbathing. Her prudish cosine thought she was improper but she said there is no sin in getting a tan.

Nice puzzle. No guessing is needed; two-way logic (I believe this is the name) is required at least two times, both related to columns 2 and 6. Very nice, I really enjoyed it.

Thanks for sharing.

no guessing

line logic gets you nearly halfway done

simple contradiction logic lets you fill in the last 2 pixels on the right half (the 2 remaining pixels from c16/17 both cant both go in r2 so at least one of them has to go in r4 which means they both have to go in r4) and now you are halfway done

the 1 clue from c3 must either go in r1 or r10 (if you have correctly placed dots via line logic in c2-9) which means one of the 3 clues from r1 and r10 must go to the right into c5 which has only a 1 clue in it
this means you can place dots in r2-9 of c5 (some of which will have already been placed) followed by more line logic to finish

nice solve

I like Brian's joke better :) I made the Sum backwards the first time, too, but I was able to quickly backtrack and finish the puzzle.

funny jokes.

If the integral of e = e, and e = mc squared, does the integral of e = mc squared? Yeesh, I'm getting a headache!
#9: Brian Bellis (mootpoint) on May 24, 2011 [SPOILER]
All e's are not created equal. The capital E in Einstein's famous equation is energy. Whereas the lower case e in mathematics is the inverse of natural logorithms and is usually written as e^x (e to the x). Confused yet?

Actually, that helps a great deal. Thanks, Brian.

I ended up dotting R3C2-R8C2, otherwise both R1C5 and R10C5 would be black causing column 5 to be invalid. The rest was line logic. Very fun to solve.

Found to be logically solvable by gator.

Is it sad that I actually laughed out loud when I read the description? I guess that just shows how much of a math nerd I am. haha I did love my calc class.

I did it like bugaboo, but only his second step. The pixels in his first one will then follow with line logic.

I was always taught that since e is a constant, the integral of e is ex+c. Even if you assume it is e**x, you still need to add c.
