Does time really slow down in relativity, or is it an illusion caused by the Doppler shifting of light?
Is time dilation an illusion?
I'm using Ubuntu GNOME 16.10 and was trying to install WPS Office. I tried to install using software centre But it wasn't installing without giving any error logs. Then I opened it with Gdebi installer. Here is what I saw.    I have already trying enabling multiverse repositories.  Edit: I have downloaded the amd64 package from the WPS official site, but even now installing through terminal I still get the missing dependencies error. How to Deserialize XML document I have 2-3 different column names that I want to look up in the entire DB and list out all tables which have those columns. Any easy script? "In back of'' vs. "back of" vs. the spatial sense of "behind" in AmE I have a polygon shape file that has many overlapping features. Each feature represents an area used by polar bears. So some of the polygons overlap and some don't, and there are separate clusters of overlapping areas.   I would like to get a measure of how much overlap there is in a particular area. But I have no clue how to do this. I'm pretty new to GIS and am still learning the ropes, it just seems I can't find an answer. How do I escape the wildcard/asterisk character in bash? For example:  me$ FOO="BAR * BAR" me$ echo $FOO BAR file1 file2 file3 file4 BAR   and using the \ escape character:  me$ FOO="BAR \* BAR" me$ echo $FOO BAR \* BAR   I'm obviously doing something stupid.  How do I get the output BAR * BAR? How can I prove the following?  $\gamma (t)$ is unit speed, $\dot \gamma(t) \not= 0 \Rightarrow \ddot \gamma(t)$ is perpendicular to $\gamma(t)$   I don't really see where a problem would arise when $\dot \gamma(t)=0$ would cause such a problem How to specify an arbitrary (possibly non-integer) font size in LaTeX I may be wrong, but it seems to me that I cannot obtain non-integer (or non-preloaded) font sizes (say, 9.876pt) using \fontsize.  If this is true, how do I do this in LaTeX?  Do I have to resort to the \font ... at ... primitive?  (The reason I need this is that I'd like to implement a more LaTeXy way to do the \diminuendo macro from .) Why can't I log into minecraft with a mojang account? Quadratic substitution question: applying substitution $p=x+\frac1x$ to $2x^4+x^3-6x^2+x+2=0$ By using the substitution $p=x+\frac{1}{x}$, show that the equation $$2x^4+x^3-6x^2+x+2=0$$ reduces to $2p^2+p-10=0$.  I can't think of anything that produces a useful result, I tried writing p as $p=\frac{x^2+1}{x}$ and finding areas to substitute but have come with no progress. Could someone offer a slight hint on how to proceed?  Thanks How to imitate commercial fried chicken? I'm trying to develop my own "secret" fried chicken recipe, something that is similar to Popeye's or Church's. I'm a LONG ways from getting there. Here's what I did in my last experiment:   Chicken was marinated in buttermilk with Cajun spices and Tabasco sauce for 24 hours I used a deep fryer and canola oil. 175C. Prior to "dressing" the chicken, I let the excess buttermilk brine drip off the chicken. I then seasoned it with Cajun seasoning I made a batter using an egg, self rising flour, milk, baking powder I also tried using just plain flour for breading   Results:   Using the batter, the chicken came out looking burned and too smooth (didn't have that crunchy look). It burned too much that I couldn't finish cooking the chicken. Using the flour, the chicken came out with a thin crust, somewhat crispy, but also too burnt. Dipping the chicken in the batter AND then flour gave a bulky &amp; crunchy look. However, again, the result looked too burnt.   Modifications:  I then changed the the breading. I used bread flour and corn starch. I dipped the chicken in the batter again, then used the new breading. The bread flour was a bit lighter. And the corn starch was even more lighter. But they were still burn looking (just lighter shades). I also dropped the temperature to 160C.  Results:  Burnt chicken whose crust wasn't really sticking to the skin/meat.  Questions:  Any suggestions on what I can do to improve? I'm guessing something in the batter is causing the burnt coat. What flour should I use? What can I do to make the coat stick to the skin/meat? Any other suggestions on what to do? So I'm going to be starting a Job here in a few weeks, I've been doing QA for about 6 years now. Pretty much your standard Test Plans/Testing with a little normal SysAdmin stuff that sometimes comes with the task. I've had some good ideas implemented in companies, as far as tracking requirements/test plans/issues differently, and they seem successful. However, this new position will be me laying down the foundation for QA. Right now things are done in what seems to be as needed as far as QA goes, requirements are gathered and sometimes kept in different locations, same with test plans (which are done by developers right now). So my job will be sort of centralizing this, or developing a Flexible way of QA'ing the Software (Web/Mobile development). So it seems the challenge will be centralizing everything, while creating test plans/ or ways of testing similar requirements that is flexible enough to span projects. I've had a few ideas, however, all my previous test work was windows based (So test plans in TFS or Microsoft Test Manager). I wanted to get some ideas from everyone here, or anyone that has started a QA department from scratch. I was also going to see if there were any books on the subject. My thoughts were mainly keeping projects separated for issue tracking (not sure of the software we will use yet). And keeping test plans for common I guess &quot;actions/elements&quot; that are repeated between different customers and executing those. Eventually maybe using selenium to save those &quot;common&quot; elements as test scripts. But I've never set something up like this before solo, so I've been doing quite a bit of reading. Any books/suggestions would be appreciated! What would you call a word that doesn't exist in or translate well into another language?

Prove that $x^2 + y^2 = 3(z^2 + m^2)$ has no solutions in integer My settlement was attacked by some Raiders and my defenses took care of them along with some of my NPC's. It seems like the Raiders didn't make it through to any of the buildings. What happens when they do?  Can you lose your items if you stored them in a house?  Can the NPC's die?  Do the enemies destroy your buildings? Store table in separate filegroup in SQL Server I have big SQL Server database, with a lot of blob data in some tables.  For performance optimization, I want to move one table to separate hard drive.  I created new filegroup, and "row data" file.  But, I can't change any parameters in table properties: they are all disabled.  And I don't know a way to enable it.  Can anybody help me? mv : not found when executed from script that modifies PATH variable I have this in my script. But is returning an error.

What wand was used by Mr Graves at the time of Fantastic Beasts? We know that the movie Fantastic Beasts is set in 1926. From the movie, we learn that at this time, Dumbledore is a teacher at Hogwarts and Grindelwald is lose after escaping a previous arrest. In the movie we learn that      Mr Graves is in fact Grindelwald in disguise. Grindelwald is shown to be at least in his forties, maybe fifties so he should already be the owner of the wand since he stole it from Gregorovitch as a teen.   We know that Dumbledore won the wand from Grindelwald after defeating him in their historic duel. That duel is always described as being “the end of the dark wizard Grindelwald” so I’m assuming that it didn’t happen prior to the movie and that he didn’t escape after that duel, please correct me if you have cannon evidence stating the contrary.      In the movie, we see Graves’ wand a few time and it isn’t the (very recognizable) one used in DH as the Elder Wand. This could of course be a prop error but since David Yates was also the director on DH and a lot of the visuals are similar I’m assuming it wasn’t. Graves could of course be using another wand in the fear that someone could recognize it but he would still be the rightful master of the Elder Wand. At the end of the movie, Newt is the one that disarms Graves/Grindelwald.   In all logic, he should have been made the new owner of the wand, whether Grindelwald was actually using it or not. That would have made it impossible for Dumbledore to win it from Grindelwald later.  So my question is: What wand is that character using at that specific time? Is he already the owner of the Elder Wand?      And if so, why wasn’t Newt made the new owner of the wand? Novel about a dragon lord who has to wear gloves at all times I read this novel when I was young. It is probably a children's or young adult novel. I think I read it in 1997 or earlier. I remember very much enjoying it, but the title and most of the details are unfortunately quite hazy for me. Here is what I have:   The main character was a girl in her early teens (I think) She was sent to live with a man who was some sort of master of dragons She may have been related to this man (his niece, perhaps), but I also may have made that up The man wore gloves at all times. When he removed them and touched someone he could see something about them. Their future, I think?   Sound familiar to anyone?   Update: Thinking back on it some more, I think I remember that the dragon lord guy and the heroine ended up in some kind of romantic relationship (making it less likely that he was her uncle). Also, he did at one point take off his gloves and touch her, seeing her future (I think).  'nother Update: It's possible that I'm confusing dragons with volcanos. Or, there may have been both. And I think they lived on an island, or a coastline?
