The region that is now the country of Iran has been known by many different names, and has had varying boundaries and borders over the past 5000 years. The name Iran comes from the Avestan word airyānąm, appearing in the time of Cyrus the Great (4th century BC).

> Two new notions of infinity challenge a long-standing plan to define the mathematical universe.
>
> Last winter, at a meeting in the Finnish wilderness high above the Arctic Circle, a group of mathematicians gathered to contemplate the fate of a mathematical universe.
>
> It was minus 20 degrees Celsius, and while some went cross-country skiing, Juan Aguilera(opens a new tab), a set theorist at the Vienna University of Technology, preferred to linger in the cafeteria, tearing pieces of pulla pastry and debating the nature of two new notions of infinity. The consequences, Aguilera believed, were grand. “We just don’t know what they are yet,” he said.
>
> Infinity, counterintuitively, comes in many shapes and sizes. This has been known since the 1870s, when the German mathematician Georg Cantor proved that the set of real numbers (all the numbers on the number line) is larger than the set of whole numbers, even though both sets are infinite. (The short version: No matter how you try to match real numbers to whole numbers, you’ll always end up with more real numbers.) The two sets, Cantor argued, represented entirely different flavors of infinity and therefore had profoundly different properties.
>
> From there, Cantor constructed larger infinities, too. He took the set of real numbers, built a new set out of all of its subsets, then proved that this new set was bigger than the original set of real numbers. And when he took all the subsets of this new set, he got an even bigger set. In this way, he built infinitely many sets, each larger than the last. He referred to the different sizes of these infinite sets as cardinal numbers (not to be confused with the ordinary cardinals 1, 2, 3…).

Why No Coin Control on Electrum Android?

Say you've got a thousand addresses and you just wanna send from two of them. How do you pull that off on the Android app?

I'm aware it's a desktop thing, and we can freeze addresses on the mobile version. But I'm really curious about the justification for not having it on Android. Is it just too much of a pain to implement?
