As I said in my first post... 39(12/13)(1) should NOT be there as the (1) is actually (0)...can you see that? and 60(4/5)(3) is actually 60(4/5)(2) once you have got these you should get 95 Nm for your answers

firstly, I don't think 20(4) -39(5/surd 26(3)) +39(1/surd26)(1) -60(3/5)(1)+60(4/5)(3) would yield 80.9 The term 39(1/ Sqrt[26])(1) should not be there... 60 (4/5)(3) the (3) should be a (2) however with these adjustments, the answer is still not 95 Nm clockwise by my calculations (more like...

so glad to see this has finally happened. I was in my final years at high school when Super-K announced their results... and somehow I moved into the topic of neutrino models at uni

velocity is a vector and has two components (e.g. v_x and v_y)

Z boson is the mediator for weak interactions. This is how electrons (or other leptons) can interact with neutrinos (which are otherwise neutral). Now, why "virtual particles" are in the mix of all this discussion confuses me. The only scenario where a virtual neutrino mediator may arise here...

at high energy colliders, pair productions and annihilations are common phenomena, but this is unrelated to the "virtual particle pairs" mentioned (what ever this statement initially intended to mean?!).

perhaps starts by determining a and b in terms of k?

Limbaugh is a joke. hehehe... Steele got it right, Limbaugh is an entertainer, period. IF the Republican party wants a joker to be their leader or chief spokeman and to rally their base... well, here is an advice from Batman: if you play with fire, you will eventually get burnt. :smile: IF...

Thanks for the link.

There is no need to go into technicalities. The situation was clear (to some extend): Israeli soldiers fired at the school etc with civilians in it. The issue for me was really whether Israeli soldiers should knowingly fire at (what you may call) civilians at the target (now, there could even be...

thanks for the comments. oh, is that why eh? ok... :smile: either way, should be a good opportunity for me to learn more about astro/cosmology...

the way I have written it, d' is not actually d in the defintion of: a_n = a_1 + d (n-1) so I put the "prime" or apostrophe on it. But the difference between two consecutive d' is the d we are after... write down the sequence and the progression and work out the differences between consecutive...

Even the Israeli spokepersons were saying that they knew "innocent" ppl were in those buildings when they fired at it, but their excuse was that they were fired at by Hamas first (who continually use civilians as "human shields") and their actions were self-defence. ok then, the question is...

I heard that this year is the Year of Astronomy. Being a "physicist" at the university, a local science teacher invited me to help out with writing some talks/presentations for the students at their high school on the topics of astrophysics... So, why 2009? What is so special? What is going...

d = 6, from {d'}_{n} = S_{n+1} - S_{n} and then evaluate d = {d'}_{n+1} - {d'}_n =6 and note that a_1 = S_1
