I'm not sure when your last spacewalk was, but you probably remember it being a bit difficult to manipulate objects, what with the gloves and the microgravity and all. As such, your tools were tethered, though that doesn't necessarily mean your tool bag can't float away . Now imagine a robot arm trying to manage the same. Even here on Earth, robots struggle with even the most mundane manipulations.
Wie in jeder guten Gesellschaft, finden sich auch in Herden Rinder unterschiedlicher Größe und Alters. Männliche Tiere sind in der Regel größer als die Kühe, Kälber müssen weniger fressen als die Alten. In der Folge sind die Jüngeren eher fertig mit dem Fressen und verdauen auch schneller. „Es gibt bei Rindern eine Art Spannung zwischen den eigenen Bedürfnissen und den Bedürfnissen der Herde”, sagt Erik Bollt, Co-Autor der Studie und Direktor des Clarkson Center for Complex Systems Science.
In the rivers of China and Japan dwells a salamander so huge that it positively dwarfs its American cousin, the massive 2.5-foot “snot otter” (which, as it happens, is what they called me in high school). This is the giant salamander, a remarkable human-sized amphibian that has remained almost unchanged for millions of years, hiding on river bottoms and hoovering up fish into its gaping maw. It smells like pepper, it’s astonishingly quick, and it makes noises that sound a bit like a child.
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".
