If the Air Force gets its way, the service soon could be losing more than 100 A-10 Thunderbolt IIs. It's the latest twist in a long fight over the future of the iconic ground-attack airplane. The Air Force has 283 A-10s divided into nine squadrons, and as DefenseNews reports today, the service's 2018 budget includes money to operate and maintain all of them. The problem is that these older planes need new wing sets because many of the wings are reaching the end of their operational lifetimes.
Sailing is hardly even sailing anymore. It's flying. The yachts of the America's Cup, happening this month in Bermuda, ride up out of the water on tiny foils that are like surfboards, which allows them to reach speeds unheard of just a few years ago. To understand all the engineering that makes it possible, you can watch Surface to Air, a short film that chronicles the story of the Swedish ARTEMIS team sponsored by Altair Engineering.
The best kinds of ideas about numbers are easy to understand but devilish to actually prove. We saw that in the YouTube channel Numberphile’s video about the Collatz conjecture. Now that channel and the same professor are back to talk about Goldbach’s conjecture. The conjecture says this: Every even integer greater than 2 can be expressed as the sum of two primes. If you think about small numbers, this is simple. Start with 4—it’s the sum of 2 and 2, and 2 is a prime number.
Muck Rack makes it simple to find people, tweets, or articles that mention any name, keyword, company, hashtag etc. We've compiled this guide to help you make the most of your search.
Selecting a term
Start searching tweets, articles from media outlets, articles mentioned in tweets, journalists'
names, titles and bios with some suggested searches:
Companies or Topics (e.g. iPhone, Microsoft)
Phrases (e.g. "cloud computing") — use quotes to keep the terms together
Twitter handles (e.g. @username) — returns those who have mentioned or replied to
Names (e.g. "David Pogue")
Hashtags (e.g. #sxsw, #london2012)
Bio details (e.g. vegan, Olympics, father)
Muck Rack's Advanced Search allows for many boolean operators.
Find results that mention multiple specified terms, use AND or
+. For example, ensure each result contains both Elon Musk and Mark Zuckerberg by
searching Obama AND Romney or Obama + Romney.
Use the operators OR or , to broaden your search when you'd like either of
multiple terms to appear in results. (This is the default behavior of our search when no operators
are used.) For example, search for democrat OR republican to find results that refer to
Democrats and/or Republicans.
Use NOT or - to subtract results from your search. For
example, searching Disney will yield results about the Walt Disney Company as well as Walt Disney
World Resort. To exclude mentions of Disney World, search for Disney -World or Disney
When using one of these operators with a phrase, enclose it in quotation marks. For example, you can
find results about smartphones excluding Apple's iPhone 4S by searching smartphone -"iPhone
Exact case matching or punctuation
If you're searching for a brand name or keyword that relies on specific punctuation marks or capitalization, you can
find results that match your exact query by adding matchcase: before the keyword you're searching for, like matchcase:E*TRADE .
Use parentheses to separate multiple
boolean phrases. For example, to find journalists talking about having fun in Disney World or
Disneyland, search for ("disney world" OR disneyland) AND fun.
An asterisk can be used to search for any variation of a root word truncated by the asterisk. For example, searching for admin* will return results for administrator, administration, administer, administered, etc.
A near operator is an AND operator where you can control the distance between the words. You can vary the distance the near operation uses by adding a forward slash and number (between 0-99) such as strawberries NEAR/10 "whipped cream", which means the strawberries must exist within 10 words of "whipped cream".
