My 2 year old son loves numbers. He can count by himself well into the 50s and can tell you what number he's looking at to at least as high as 110. As for me, well, numbers and I have never been the best of friends. How can I, a numbers-adverse dad, encourage and nurture his talent? [more inside]
I would write "1950s" or "1980s", and this is universal among native English speakers, so far as I am aware. In international contexts, however, I sometimes observe that people whose English spelling is otherwise flawless will consistently write "1950ies" or "1980ies", which reads to me like it has an extra syllable. Where does this convention come from, and what linguistic background makes it sound like a reasonable way to contract these numbers? [more inside]
I have an original pet theory I came up with a long time ago involving the Internet and how people judge probability. It probably would fall into the anthropological, sociological or psychological fields. I'm not intending to make this post to discuss the theory itself as a sort of "let's b.s. back and forth about my idea" kind of thing. Reason I'm posting is because I'd like to know if this theory already exists or is an application of something broader that already exists. Maybe it's a theory being applied onto the communications medium of the Internet of some older theory in one of the above field(s) of study, or maybe it's a piecemeal construction of a few theories spliced together. Anyway, enough babbling, actual theory after the cut. [more inside]

I'm in the earliest possible stages of building a web interface that will make it easy to display, graph, download, summarize, and interact with a wide variety of data. If you use scientific data from the internet, what are some of the websites you've encountered that make using data the easiest, most intuitive, and give you the best control? Also, what are some must-have features for you, and some of the best and worst design decisions the site builders have made? [more inside]

At the local dog park, someone apparently found two Post-it notes, covered in strange number pairs, and pinned them to the lost&found board because, well, they look like they might be important! Since then, there's been much speculation about what these numbers might be for, what they might mean. Rather then type it all out, I have an image of the notes themselves, here. [more inside]
I'm thinking about setting up a tongue in cheek project for Halloween that involves showing numbers that are scary. What numbers (with the context of a description) make you anxious, or at least spook you a bit on first glance? [more inside]
A question that came up in discussion with my baseball-loving son: which uniform number has the most career home runs? In other words: which N gives the maximum value of the number of home runs hit by players wearing uniform N (at the time of the home run?) I was hoping one of the tools at baseball-reference would be able to compute this for me, but I didn't find it there. Some contenders are #44 (Hank Aaron, Reggie Jackson), #25 (Bonds as a Giant, Thome, Palmeiro) and #3 (late Ruth, pre-Yankee A. Rodriguez, Foxx, Killebrew)
I want to create a form with Open Office that lets me enter numbers in the right column of a page that corresponds to the text in the left. I want to be able to past the entire text document into the right column and have the left column remain blank for my entries. A spreadsheet won't work because the text won't word wrap. I've also tried a table and inserting a column into a text document. I've also tried to write in the margin, but I'll be moving a lot of documents, so I don't want to do a lot of specific typing, which would likely be spread across thousands of pages of documents. I'd like to automate and past as much of this as possible. Think of how books of poetry or philosophy number each line of corresponding text, making it easy to find a specific verse. That's the form I want to create. Or if it has already been created and exists somewhere, I'd gladly download it. Help.

In English we have grouping units like dozen (12), gross (144), score (20) and a few others. Though no one uses them for counting (eg: 18, 19, score, 21…). What are similar words in other languages? If there's a cultural or historic reason that particular number has a special word, all the better.

Can a transcendental number such as pi, be raised to an irrational, but algebraic power resulting in an algebraic solution? Complex solutions would be acceptable. There might be a quick proof here, or there might not be. - Thanks for any help you can offer answering this! (And I promise that this isn't for a class or anything like that!)
I'm a 21 year old college senior liberal arts major who has managed to slide by in school (and life) without ever really learning math beyond a middle school/very early high school level.

Why does the New York Times write "unemployment rose to 10% from 5%" rather than "unemployment rose from 5% to 10%"? I trip over this formulation and have to go back and reread the clause every time.

What are your benchmarks for estimating/comprehending quantities? I'm terrible with magnitudes; if someone tells me that they weigh 85kg, or that they come from a city of 2 million people, this doesn't create a mental picture for me at all; they might as well be speaking another language. After a lifetime of being resigned to this, I've decided I'm going to familiarise myself with a list of benchmark quantities: my height, the height of my tallest friend, population of my city, etc. Help me compile a list of quantities I should be familiar with, and tips for learning to come to grips with quantities!
