Is there a dollar amount that, when adding Massachusetts Sales Tax, precisely equals $200? Has any Dark Force user/ally ever said "May the Force be with you"? Gnome keyring daemon not starting up properly How to add field history and product as a related list of opportunity in vf page I am trying the below code to add field history and product as a related list of opportunity in vf page, but its not working .  &lt;apex:relatedList list="OpportunityFieldHistory"/&gt; &lt;apex:relatedList list="Product"/&gt;   Can anyone tell me what is the correct way to write it.  Regards    Edit:  There are two Standard objects that have Opportunity history information,  and . The relatedList component works fine with a value of OpportunityHistories for the list attribute, but an error is thrown when using the value of Histories, even though the SObject describe information shows "Histories" as the child relationship name.   &lt;apex:relatedList list="OpportunityHistories"/&gt; &lt;!-- Works fine --&gt; &lt;apex:relatedList list="Histories"/&gt;            &lt;!-- Error --&gt; Java: Avoid inserting duplicate in arraylist How to split strings into text and number? I'd like to split strings like these  'foofo21' 'bar432' 'foobar12345'   into  ['foofo', '21'] ['bar', '432'] ['foobar', '12345']   Does somebody know an easy and simple way to do this in python? Is there a way of conditionally triggering a compile-time error in verilog? Why did Owen Chase not fire his harpoon at Moby Dick? In movie In the Heart of the Sea, when Owen Chase finally faces the big white whale (later named Moby Dick) with his harpoon, why does he not do it? No Line Break in Author Command? It goes off the page! Is it grammatical to omit the subject from "I did my work"? A couple years ago I ran upon a  video demonstrating how researchers used x-rays given off by tearing tape off its spindle in hopes to miniaturized and cheapen future x-ray devices. As of late I have been wondering what interactions are causing this. I understood from the video that the electrons are being ejected due to the added energy to the system (peeling). This instinctively pointed me towards QED where interactions between electrons produce a photon for short periods. 1)Are those same photons from electron interaction the resulting x-rays? 2)Are the frequencies of the photons being limited by the $\Delta$energy$\Delta$time uncertainty, and/or $\Delta$position$\Delta$momentum uncertainty (at the vertex of the ripping tape, where high densities of electrons may accumulate) ? Note: I've also considered that the van der Waals force may come into consideration, not certain though. Looking for a QED based descriptions/answers. Any elementary references to this work is appreciated. Is it possible to assign the same value to multiple keys in a dict object at once? Find the value of $P(1)$ Let $P (x) = x^2 + bx + c$, where $b$ and $c$ are integer.       If $P(x)$ is a factor of both $x^4 + 6x^2 + 25$ and $3x^4 + 4x^2 + 28x  + 5$, find the value of $P(1)$.   I am not being able to solve this.Some hints/suggestions?  Tell me if I can edit to improve this question.I could'nt try much.Got stuck. I'm taking a complex analysis course and doing some practice computing residues &amp; evaluating integrals. I pulled out an old book called     On page 196-197, there are some interesting integrals to evaluate. I'm at 5.4.3.10.: I was able to do question 1, but was stumped at how to even begin with question 2:     Evaluate the integral   $$\int_0^{2 \pi} e^{\cos x} \cos (nx - \sin x) \,dx ,$$   where $n$ is an natural number.   The answer is simply $\frac{2 \pi}{n}$. Any hints? Do dual American and Mexican citizens need passports to travel between the US and Mexico? I have 2 children that were born in Mexico. They have a birth certificate abroad. So this is dual citizenship. Do they need passports?  My kids were born in Durango, Mexico. I am American. Their father is Mexican. They were both given birth certificates abroad. They are now 16 and 14. They want to go visit grandparents and aunts and uncles in Mexico.  Will they need to get a passport to enter Mexico?  Will they need it to fly? My 3 years old doesn't tell me when he needs to use the bathroom My son is 3 years old and doesn't tell me when he needs to use the bathroom. It has been 5 months now that I took his diaper off him. I just do not know what I should do.  Should I put a diaper on him again?  I mean, is this normal? Please help. I get frustrated sometimes.  He doesn't want to potty at all! I did train him before but now that he understands, he doesn't want to go to potty. Is there anything that is totally random? When I say totally random, I mean absolutely random, not pseudorandom. If I want to say "totally random" numbers such as 1,26,17,4,1 and 27, although I see them to be totally random, they aren't. These are numbers that I think are influenced by my childhood, ideology and everything that I've seen. So, what do you think? Is there anything completely random? How to get a combined ticket in IRCTC (Indian Railway) Suppose I want to go from Station A to Station C but Station C is not a stoppage of some train say train 01, so I can get a combined ticket from station A to Station B  through train 01 plus Station B to station C through a different train say 02, so my total fare will be of same ticket as from Station A to Station C.  We can get Combined ticket from the Booking Window but how's that possible on the IRCTC website? A square matrix $n \times n$ is an invertible matrix iff the rank of the matrix is $n$.
