Maximum sum of numbers, one from each set, with constraints

Working on a personal project, I am running into a number of math problems of the kind described within. I am not a math expert, so I don't know what to call these kinds of problems, so I don't know how to search for information about them. [more inside]

Did Charles Babbage ever read Leibniz on logic?

Charles Babbage was a prominent member of the Analytical Society, and was at the very least intimately familiar with Leibniz's formulation of calculus. But did he ever read Leibniz's writings on logic? Did the Ars Combinatoria, or any of his writings on the "universal characteristic" or "calculus ratiocinator" influence Babbage's thinking about computation?

Fallacies and Errors in Inferential Statistics

I have recently been introduced to the concept of pseudoreplication as a mistake that people often make when using inferential statistics to evaluate treatment outcomes. My field (evolutionary and conservation biology) makes heavy use of inferential statistics, including techniques that are vulnerable to pseudoreplication, yet nowhere in my formal education have I been taught about how poor experimental design and lack of statistical rigor can lead to fallacies like this. My personal statistical proficiency is poor, but I am working to remedy that. To that end, could folks help me by identifying and ideally explaining whatever other potential pitfalls you can think of, and explaining how they can be avoided through careful experimental design and data-analysis?

How come these instances of modus tollens seem so weird?

Basic logic question. The validity of modus tollens is intuitive when the antecedent and consequent in the first conditional premise aren't negative statements. But whenever the argument begins with something like "If not-p, then q", the whole thing seems less intuitive to me. Can someone explain to my very rusty brain why those instances of modus tollens are still valid? [more inside]

What does the phrase "accounting logic" mean, particularly as used in the new book Monoculture?

I'm reading the book Monoculture by FS Michaels, which describes how what the author calls "the economic story," which she sees as dominant in our culture and as having replaced earlier dominant stories rooted in religion and science, is shaping people's work, communities, education, and relationships. In the book, Michaels talks about how "as the economic story spreads to government, a language based on economics develops along with a new way of thinking and reasoning about what goes on in government -- a kind of accounting logic. That accounting logic makes two assumptions: first, that anything and everything your government does can be assessed in terms of what value is added, and second, that the value added can be linked to how much money is spent on the activity in the first place." Etc. My question is: in this context, what does the phrase "accounting logic" mean? [more inside]

How to uninstall Logic Studio safely

I got Logic Studio and installed it on my Mac, then realized I should have installed a bunch of the files onto an external hard drive instead of my computer's hard drive. I thought I would do a complete uninstall and then reinstall the way I should have initially, but from my research, it seems uninstalling Logic is kind of a big, scary deal. Can you please walk me through how to fix this situation using small, easy-to-understand words? [more inside]

What are some activities that exercise visual or structural type thinking? Something to do with science, technology, or 3-dimensions preferred.

Pie is greater than not pie.

I'm trying to express my love for a certain dessert in a math/logic formula. I have this: π > ∼π , which I take to mean "Pi is greater than not Pi", and this: π > ∞-π, which I take to mean "Pi is greater than Everything but Pi". Do these make any sense or hold up in any legit way?

Is there a good introduction to puzzle logic out there?

I recently read through the Problem Sleuth section of MS Paint Adventures and loved it to pieces. However, it reminded me that the kind of logic employed in adventure game puzzles has always flustered me. Are there any good resources that pull back the curtain on how these kinds of logic/linear thinking puzzles are constructed? I've seen or played loads of examples, but never seen anything that really breaks them down into their components.
