Can a penalty kick be passed to a second player?
Are players allowed to pass a penalty kick?
KernelEvents::REQUEST is not fired on cached pages Let's say I have two planets that are one hundred thousand lightyears away from each other. I and my immortal friend on the other planet want to communicate, with a strong laser and a tachyon communication device.  I record a message on the tachyon communication device and release the message at exactly the same time as I activate the laser, both of which are directed to the other planet which is one hundred thousand lightyears away. Say it is the year 0 for both of us at the time I did this.  If tachyons existed, then the message would arrive to my friend before the photons in the laser. It would arrive, say, a thousand years earlier. From my vantage point, that message will arrive to her at year 99,999; the same would be true for my friend's vantage point. However, she will only see the laser at year 100,000.  So since she got the message at year 99,999, she immediately sends me a reply back going through the same procedure as I did. She records a message and releases it at the same time as the laser. The tachyons will arrive 1,000 years earlier than the laser, so for me, I will receive the message at year 199,998. I will receive the laser, however, at year 199,999.  It seems to me that communication this way does not violate causality. I will still have received the message after I had sent it.   If tachyons truly violated causality, though, I realize it should arrive at year -1 for her, and so she can reply to me at year -2, which would mess me up by year 0 as I will ask her how she knew I was planning on sending her a message before I sent it. I could send her a different message, which she would end up receiving at year -1, and will end up confusing her as she would have received one message asking her out, and the other asking her how did she know I was asking her out. She then decides I am crazy and sends me a message at year -2 that she does not want to date me, and so she will have both turned me down and entertained me before I have even asked her out.  On the other hand, let's go back to year 0 and add a third device to our list: an Alcubierre drive. After I send out the message and the laser, I get impatient and do not feel like waiting 99,999 years, so I get on my Alcubierre drive spaceship and arrive on her planet at the same year 0. My friend is not in her office, so I leave a note to her also immortal secretary saying I dropped by and that she should expect a message for her in year 99,999.  I then get back on my Alcubierre drive and land back on my planet, still on year 0. Meanwhile, the tachyons and photons I sent out are still racing to arrive to her. By year 99,999, she receives the message just as I Alcubierre drive back to her, and I pick her up for dinner.  But the point of my question is, it seems to me that just going faster than light, if that alone was what you had, would not violate causality. It must be something else. I understand time dilation and that things with mass cannot travel at the speed of light, but using the Alcubierre drive, hypothetically speaking, I was still able to outpace the photons while also having mass. It still did not produce causality problems. Alcubierre drives are also valid solutions to GR.  It seems circular to me to say that what makes traveling faster than light violate causality is because it violates causality (if faster than light communication was divorced from causality problems, then the causality problem would cause itself -- thereby violating causality and, hence, we would scrap it and conclude that there is no causality problem after all).  What is it that I am missing? If someone could help me out, that would be excellent. I've been itching to ask my friend out for a few millenia now. :) I cannot boot to the desktop because I filled the file system. How do I reclaim some space? My memory is completely full when I tried following the data recovery and copied the wrong file using command line tool Test Disk. As it was taking so long to copy, I turned it off and I realized I copied the wrong file. Now my laptop memory is now full and lead me to more problems.  I have had similar problems to :       Now my screen keeps blinking:   Can anybody help? Many thanks. Wish you all the best. Prove that , any primitive root $r$ of $p^n$ is also a primitive root of $p$ Find the number of zeroes (counting multiplicity) of $p(z)=z^6+z^3+10z^2+4z+3$ inside the annulus $1&lt;|z|&lt;2$. I think this can be solved using Rouché’s theorem. First consider $|z|\leq 1$ on the boundary $|z|=1$ and $|z^6+z^3|&lt;|10z^2+4z+3|$ which can be shown using triangle inequalities, the left side is at most $2$ while right side is at least $3$. We could also consider $|z|\leq 1+ \epsilon$ and our proof still works. Thus $p(z)$ has 2 roots inside $|z|\leq 1$. Also for $|z|= 2$ we have $|z^6+z^3|&gt;|10z^2+4z+3|$. Thus we have 6 zeroes of $p(z)$ inside $|z|&lt;2$ and therefore 4 of them are in $1&lt;|z|&lt;2$. Is this correct? The only &quot;tricky&quot; part is ruling out that there are zeros on $|z|=1$. Is the trace of inverse matrix convex? When one hears that something smells, one would generally assume that it smells bad.   Isn't there a word which wouldn't bring to mind the idea of a bad odor? For example, how would you describe pot-pourri (assuming you like the smell of pot-pourri)? If possible, I would like an adjective, or a word that could takes the place of an adjective. How can I make content disappear when a user logs in? I am working in Wordpress, and I would like to make certain elements disappear once a user logs in. How can I do this?  I have social icons on my page that I positioned to the center of my menu bar at the top of my website.  those icons are generated by a plugin  that is what i want to disappear I am trying to use the MailManager class in Drupal 8 to send HTML mail. I got it working, but it isn't parsing the HTML markup. I think something is wrong with the headers of the email.  What I have is a custom module (Custom_forward) that contains a form and that calls Mailmanager::mail() in its submitForm() method, which contains the following code.          // Email body         $header = $sender . ' thought you would like to see this page from the website.';         $personal_message = $form_state-&gt;getValues()['message_body'];         $entity_url_value = '&lt;a href="' . $entity_url-&gt;toString() . '"&gt;Go to article&lt;/a&gt;';         $message = $header . '&lt;br&gt;' . $personal_message . '&lt;br&gt;' . $entity_url_value;          // Email         $langcode = 'en';         $mailManager = \Drupal::service('plugin.manager.mail');         $to = $form_state-&gt;getValues()['recipient'];          $params['title'] = 'Forward';         $params['message'] = $message;         $result = $mailManager-&gt;mail('custom_forward', 'forward', $to, $langcode, $params, NULL, true);          if ($result['result'] !== true) {             drupal_set_message(t('There was a problem sending your message and it was not sent.'), 'error');             \Drupal::logger('mail-log')-&gt;error($message);         }         else {             drupal_set_message(t('Your message has been sent.'));         }   According to Drupal you also need the hook_mail method in mytheme.theme to be able to send message, you can see this method here:  function custom_forward_mail($key, &amp;$message, $params) {   $message['body'] = [];   $message['subject'] = [];   $message['headers'] = array(     'content-type' =&gt; 'text/html',     'charset' =&gt; 'UTF-8',     'format' =&gt; 'flowed',     'delsp' =&gt; 'yes',     'from' =&gt; \Drupal::config('system.site')-&gt;get('mail')   );    switch ($key) {     case 'forward':       $message['subject'] = $params['title'];       $message['body'][] = '&lt;html&gt;&lt;body&gt;' . $params['message'] . '&lt;/body&gt;&lt;/html&gt;';       break;   } }   As you can see, I am setting the content type to text/html and that should tell the mail system to parse the content as an HTML, but this is not working for some reasons.  This is a testing email. All the HTML markup is not shown, but also not working.

I have tried creating the strings a lot of different ways, but I cannot get it to leave just one quote.  Even doing a string replace has no effect.   Any idea why this is happening?

I'm looking to schedule 16 players to play a round robin tournament with each other such that there are 4 players at each table.

Evaluating even binomial coefficients Can someone give me a hint how to evaluate $$ \binom{n}{0}+\binom{n}{2}+\cdots+\binom{n}{o(n)},$$ where $o(n)$ is $n$ if $n$ is even and $n-1$ otherwise ?

Chance of selecting the last k pages in correct order from a set of n pages I have a set of documents numbered 1 to n. If I arrange the documents randomly, what is the chance of selecting the last k pages in the correct order if I select them at random from the documents?   Because order is important, I use the following formula:  $\displaystyle\frac{n!}{(n-k)!}$  From this I calculate how many ways there are to select k pages from n pages in the correct order. I need to have the last k pages. Which I can do in only one way. So is the chance   1/$\displaystyle\frac{n!}{(n-k)!}$?   It seems unlikely. It seems to me spontaneously that the chance should be smaller. Sum of First $n$ Squares Equals $\frac{n(n+1)(2n+1)}{6}$
