Today I decided to take another tour of the local university. We went into the science department first.
Suddenly, I found myself harassed by a woman in a lab coat. She exclaimed in an urgent voice, 'My experiment's gone!'
'Gone where?' you ask.
'I don't know, just gone!'
Last time you were ...
My old calculator only have numbers, ($+$) and ($\times $) keys
Using only those keys, find the last three digits precisely before the decimal point.
$(3 + \sqrt 7)^5$
Note : Actually you should be able to do the calculation by hand (without calculator or computer).
I'd hope you have many more than a few. I've definitely enjoyed talking to you and trying my hand at your puzzles, and I know others here feel the same.
Label the vertices of this graph with positive integers (repetitions allowed) whose sum is 100 in such a way that any pair of vertices are joined by an edge if (and only if) they have labels with a common divisor greater than 1 (i.e. they are not relatively prime).
That quote references this one: "One of the guys I'm with out here is a puzzler himself — he's even on that puzzle website you were telling me about. Anyway, he helped me put together a bit of a puzzle for you."
A friend of mine, one of those world-traveler, rugged outdoorsman, live-out-of-a-tent-and-backpack sorts, has just sent me an interesting email:

I had ... some constraints to work in. That makes a couple of the cryptics not quite as clean as I would have liked, but I think once you get what's going on they'll make more sense
Stepping away a bit, I'll peek in now and again. 3 (hopefully obviously) isn't a cryptic. 1 is pretty straightforward. The others, you'll probably want to keep in mind how these answers are shaping up
I was hiking in the desert this weekend and saw two people coming the other way. We nodded and smiled as we passed, and, as sometimes happens in these situations, I overheard a snippet of their conversation.
Person 1: Granite is not nice.
Person 2: I think granite is lovely.
Person 1: Me too.
