Mil Mi-22

The Mil Mi-22 was a single-engined helicopter project of the 1960s. It was similar in size and shape to the Mil Mi-2 and had problems with planned engine configuration (first W-2 config.). Later schematics interested the Russian military by illustrations of higher-capacity engine configuration, 10A GTD-940 kW to be precise, (next W-20 config.) and had an improved fuselage, unlike the earlier Mil Mi-2. It was also planned to have a four-bladed main rotor, a two-bladed tail rotor, a larger cabin than that in the Mil Mi-2, and a skid undercarriage. The Mi-22 lost out to the larger Mi-24, which had better assault/transport abilities.

.mil

The domain name mil is the sponsored top-level domain (sTLD) in the Domain Name System of the Internet for the United States Department of Defense and its subsidiary or affiliated organizations. The name is derived from military. It was one of the first top-level domains, created in January 1985.

The United States is the only country that has a top-level domain for its military, a legacy of the United States' military role in the creation of the Internet. Other countries often use second-level domains for this purpose, e.g., mod.uk for the United Kingdom's Ministry of Defence. Canada uses norad.mil with the United States as they jointly operate the North American Aerospace Defense Command.

Despite having a dedicated top-level domain, the US military also uses com domains for some of its recruitment sites, such as goarmy.com, as well as for the Defense Commissary Agency's website www.commissaries.com and most non-appropriated fund instrumentalities such as military MWR organizations and military exchanges. Also, the military uses edu domains for its service academies: the United States Military Academy, United States Coast Guard Academy, United States Naval Academy, and the United States Air Force Academy can all be reached using either an edu or a mil domain name. The official athletic program sites of the three academies that are members of NCAA Division I (Army, Navy, Air Force) use com domains. The Department of Defense itself uses gov for its home page, with at least three second-level domains within mil (defense, dod, and pentagon) redirecting to its domain name www.defense.gov.

Milü

The name Milü (Chinese: 密率; pinyin: mì lǜ; "detailed (approximation) ratio"), also known as Zulü (Zu's ratio), is given to an approximation to π (pi) found by Chinese mathematician and astronomer Zǔ Chōngzhī (祖沖之). He computed π to be between 3.1415926 and 3.1415927 and gave two rational approximations of π, 22/7 and 355/113, naming them respectively Yuelü 约率 (approximate ratio) and Milü.

355/113 is the best rational approximation of π with a denominator of four digits or fewer, being accurate to 6 decimal places. It is within 0.000009% of the value of π, or in terms of common fractions overestimates π by less than 1/3 748 629. The next rational number (ordered by size of denominator) that is a better rational approximation of π is 52 163/16 604, still only correct to 6 decimal places and hardly closer to π than 355/113. To be accurate to 7 decimal places, one needs to go as far as 86 953/27 678. For 8, we need 102 928/32 763.

An easy mnemonic helps memorize this useful fraction by writing down each of the first three odd numbers twice: 1 1 3 3 5 5, then dividing the decimal number represented by the last 3 digits by the decimal number given by the first three digits. Alternatively, 1 / π = 113 / 355.
