Subject P is presenting symptoms of schizophrenia. He has become a threat to other subjects. The experiment is being terminated, and the subject will be put down right away.

Fine, I won't call you by your nickname.

You gave the doses to the wrong subject.

Suppose we start with one electron at a certain place and time (this place and time being given the arbitrary label A) and a photon at another place and time (given the label B). A typical question from a physical standpoint is: 'What is the probability of finding an electron at C (another place and a later time) and a photon at D (yet another place and time)?'. The simplest process to achieve this end is for the electron to move from A to C (an elementary action) and that the photon moves from B to D (another elementary action). From a knowledge of the probabilities of each of these subprocesses E(A to C) and P(B to D) then we would expect to calculate the probability of both happening by multiplying them, using rule b) above. This gives a simple estimated answer to our question.

But there are other ways in which the end result could come about. The electron might move to a place and time E where it absorbs the photon; then move on before emitting another photon at F; then move on to C where it is detected, while the new photon moves on to D. The probability of this complex process can again be calculated by knowing the probabilities of each of the individual actions: three electron actions, two photon actions and two vertexes one emission and one absorption. We would expect to find the total probability by multiplying the probabilities of each of the actions, for any chosen positions of E and F. We then, using rule a) above, have to add up all these probabilities for all the alternatives for E and F. (This is not elementary in practice, and involves integration.) But there is another possibility: that is that the electron first moves to G where it emits a photon which goes on to D, while the electron moves on to H, where it absorbs the first photon, before moving on to C. Again we can calculate the probability of these possibilities (for all points G and H). We then have a better estimation for the total probability by adding the probabilities of these two possibilities to our original simple estimate. Incidentally the name given to this process of a photon interacting with an electron in this way is Compton Scattering.

There are an infinite number of other intermediate processes in which more and more photons are absorbed and/or emitted. For each of these possibilities there is a Feynman diagram describing it. This implies a complex computation for the resulting probabilities, but provided it is the case that the more complicated the diagram the less it contributes to the result, it is only a matter of time and effort to find as accurate an answer as one wants to the original question. This is the basic approach of QED. To calculate the probability of any interactive process between electrons and photons it is a matter of first noting, with Feynman diagrams, all the possible ways in which the process can be constructed from the three basic elements. Each diagram involves some calculation involving definite rules to find the associated probability. That basic scaffolding remains when one moves to a quantum description but some conceptual changes are requested. One is that whereas we might expect in our everyday life that there would be some constraints on the points to which a particle can move, that is not true in full quantum electrodynamics. There is a certain possibility of an electron or photon at A moving as a basic action to any other place and time in the universe. That includes places that could only be reached at speeds greater than that of light and also earlier times. (An electron moving backwards in time can be viewed as a positron moving forward in time.)

Претпоставимо да почнемо са једним електрон на одређеном месту и времену (ово место и сада даје произвољне ознака) и фотона на другом месту и времену (имајући у виду етикету Б). Типичан питање од физичке тачке гледишта је: "Шта је вероватноћа налажења електрона на Ц (друго место и касније) и фотона у Д (још једно место и време)?". Најједноставнији процес у остварењу тог циља је за електрон да се креће од А до Ц (основне радње) и да фотон креће од Б до Д (други основне акција). Од знања о вероватноће сваке од ових субпроцессес - Е (А до Ц) и П (Б до Д) - онда бисмо очекивали да се израчуна вероватноћа и дешава им множењем, користећи правило б) горе. Ово вам даје једноставан одговор процењује на наше питање. Али, постоје и други начини на који крајњи резултат могао доћи. Електрон може да се преселе у место и време Е где се апсорбује фотон, а затим пређите на другу пре него што емитују фотон у Ф, а затим преци на Ц где је откривен, а нови фотона прелази на Д. вероватноћа овог комплекса процес може поново бити израчуната знајући вероватноће сваке од појединачних акција: три електрона акције, два фотона акције и две вертекес - једну емисију и један апсорпцију. Очекивали бисмо да пронађе укупног вероватноћа множењем вероватноће сваке од акција, за било који одабрани позиције Е и Ф. Затим смо, користећи правило) горе, треба додати све ове вероватноће за све алтернативе за Е и Ф. (. Ово није основно у пракси, и укључује интеграцију) Али постоји и друга могућност: да је да је електрон креће први у Г где емитује фотон који иде на Д, а електрон прелази на х, где апсорбује фотон први, пре преласка на Ц. Опет можемо израчунати вероватноћу од ових могућности (за све тачке Г и Х). Затим смо се боље процена за укупну вероватноћу додајући вероватноће ове две могућности да се наш оригинални једноставна процена. Узгред име дато са овим процесом фотон интеракције са електрона на овакав начин је Комптон расејања. Постоји безброј других средњи процеса у којима се све више и више фотона апсорбује и / или емитована. За сваку од ових могућности ту је Фејнман дијаграм описујући га. То подразумева сложен прорачун за последицу вероватноће, али под условом да је случај да сложенија дијаграму мање доприноси резултат, то је само питање времена и труда да пронађе што тачније одговор неко жели да првобитно питање. Ово је основни приступ за КЕД. За израчунавање вероватноће сваког интерактивни процес између електрона и фотона то је ствар првог помена, са Фејнман дијаграма, све могуће начине на који се процес бити изграђени од три основна елемента. Сваки дијаграм укључује неколико обрачуна у вези дефинитивно правила да пронађе у вези вероватноће. Да су основни скеле остаје када се сели у квантном опису али неке концептуалне промене су тражили. Једна је да, док можемо очекивати у нашем свакодневном животу да неће бити неких ограничења на која указује на честице може да се креће, то није истина у потпуности квантној електродинамика. Постоји одређени могућност електрон или фотона у покрету, као основне мере за друго место и време у свемиру. То укључује места која би могла доћи само при брзинама већим од оне светлости и ранијих времена. (Електрон се креће уназад на време се може посматрати као позитрон креће напред у времену.)Претпоставимо да почнемо са једним електрон на одређеном месту и времену (ово место и сада даје произвољне ознака) и фотона на другом месту и времену (имајући у виду етикету Б).

Everyone, I'd like you to meet pie.

[H2PM]

Please, continue.

My fazza won't answer his phone.

Sometimes I hate being left alone this much.

Я серьезно надеюсь Вы, товарищи не делают этого.

[H2PM]

This is very interesting. Reminds me of that time when Tyler went completely crazy.

[Pepsiguy]

 

If they are together, she is cheating on him.

[H2PM]

The dreams...

[Pepsiguy]

...Are better then your wildest dreams.

Napalm, come to bed sweetie.

Hmm....

You're ex will just suck you into her vagina of hell.
