Ah, I gotcha. Yeah, the question as posed is straightforward, though there's some fun stuff (fixed points of ordinal exponentiation, inaccessibles, etc) floating around in the same neighborhood.

It's sort of interesting -- there's also no largest natural number, but we can talk about the size of their cardinality. You can't do that with all of the "infinities" since the collection of ordinals doesn't form an ordinal (Burali-Forti)

There are the same number of whole numbers as there are fractions/rational numbers (my favorite quick proof -- every whole number is a rational number (itself over 1). Map each n/m in lowest terms to 2^n*3^m for an injection of rationals i

Many sockets have little bent-wire brackets that pop into those holes when the plug is fully inserted in order to help hold it in place.

Relatedly, there was an in-channel-command bug in Twitter in 2010 that would allow you to force anyone to follow you by tweeting "accept [username]". It was discovered accidentally by a fan of a band named "Accept" tweeting "accept pwnz":

Nagel's book is a wonderful exposition (three-page-long footnotes aside). In addition to these two, I might recommend Torkel Franzén's book "Gödel's Theorem: An Incomplete Guide to Its Use and Abuse". Some of the content is fairly technic

Batista is not being downvoted because they're expressing a differing opinion. They're being downvoted because they're not taking the time to fully consider the issues and engage in reasonable debate. As an example, from their first post,

Right. So why are you wearing your belt (hooked through some fabric loops on your pants) and you're not wearing your phone (resting in a fabric pouch on your pants)?

Do you wear your belt, or is it just always with you, hooked through some loops on your pants? This isn't meant sarcastically -- the idea of "wearing" something is pretty tied up with the context of the object (e.g. is it "clothing") and le

Any small portion of the Möbius strip "looks like" a chunk of 2D object, but the entire object cannot be placed directly into 2-space. The surface of a sphere is a similar example.

I spent a ton of time years ago making molds for some of the hard-to-get plastic parts for an unusual car of mine so that I could produce my own spare parts. Simply being able to print them would be amazing. Of course, many of those parts

Your definition of "government's duty" is not universally agreed upon, and it's intellectually dishonest to predicate an argument on the presumption that it is.

This has sort of existed since the '40s, using radiant heat from the bread: http://www.automaticbeyondbelief.org/ I haven't tested this, but you're probably have issues with e.g. dark rye.

In e.g. physics or chemistry, the sciences are predicated on your ability to reduce problems to simple systems and interactions. In biology most phenomena require a large, complex, highly interactive system, which is difficult to simulate
