As I did last year, I'll be systematically bumping this thread in the hope that it will encourage more votes. So please, in celebration, of the intellectual prowess on these forums, cast your vote, and give some worthy recognition to those who clearly deserve it. DO IT ! <Chancellor Palpatine>

Not sure if this is useful information, but my first thought was controlling MIDI via bluetooth, in fact this method is becoming very popular, using Wii controllers as MIDI triggers via Reaktor, here's a link... http://createdigitalmusic.com/tag/wii/page/2/ I'll post more later, if I think of anything, bit busy at the moment.

I hope for Bellbottom's sake, it's a case of 'lost in translation.'

I object to the fact I only have two friends on my list, both very decent chaps, but still...I second Klaynos's notion.

I'm not sure that's correct, what drives a reconciling between QM and GR is that there's a discrepancy to be solved, not the belief that it will be solved. If any problem in physics, or science in general for that matter, was just shrugged at, because said scientists hit a brick wall, I think progress in the sciences would be very slow indeed. Unless you're making the same mistake I did i.e taking the word 'everything' at face value (see earlier post), then my previous point still stands. A unification of the four forces, a la quantum gravity, is not proposing an explanation of 'everything' in that sense of the word. Indeed

Can you explain your reasoning behind this... I don't understand why that's necessary. Oops, is that off topic ? I didn't see this mentioned in the article.

Flying over Mars surface (animation with real-life photography)

Permafrost has been detected around the landing site, not massively exciting, but there it is...article from physicsworld http://physicsworld.com/cws/article/news/34379;jsessionid=6E28E819B4291E21ADCC406B0A18914D -
Question about Math Tutorials
Royston replied to Reaper's topic in Suggestions, Comments and Support
As the basics of differentiation have been covered, I'd be happy to do an introduction to integration, i.e explaining the FTC. I'm busy with an assignment, but could spare a couple of hours on Sunday. -
Where Does Space End? It Must End Somewhere!
Royston replied to Edisonian's topic in Astronomy and Cosmology
Would you mind citing a reputable source, where it specifically states that please. -
To give you some background, accelerated expansion was discovered, by Adam Reiss and his team, with the first article published in 1998 in the Astrophysical journal. So I'd start your search there. The method involves observing Type 1a supernovae, for the obvious reason that they're incredibly bright...some have been visible with the naked eye. The basic method, is that you can plot the observed brightness against the Hubble redshift (don't confuse this with the doppler effect, it's not frame dependant) so the y axis would be time...the farther away the object, the further back in time you're looking. Then on the x axis, you have the a measurement of redshift (ie the wavelength of light is stretched.) So, for distant observations at a given time, the less redshift, would mean acceleration. Higher redshifts, would be the opposite...the expansion is slowing down. Here's a thread I started a while ago, that has links to future projects... http://www.scienceforums.net/forum/showthread.php?t=30633 The observations tie in and are intrinsic with the Lambda CDM model, so you may want to google that as well. But there are more than enough articles on the subject, hopefully I've given you enough information on where to look.

As I'm yet to buy any filters for my telescope, I projected an image of the Sun through the eyepiece, onto some paper. This is actually standard with my telescope, but there was obviously light scattering due to the humidity on that day, and the image was pretty uninspiring. However, here's some images using the same method...you'll need to scroll down to the bottom... http://www.tdmodels.co.uk/cpac/gallery/solarsys.htm I presume B+W would give you the sharpest contrast, and therefore clearer sunspot images, but astrophotography isn't my field...yet.

As you can see, it has been specially calibrated to fit my strict regime. I think we can all agree, this timepiece blurs the line, between practicality and elegance.

Nothing beats my trusty, sundial hat. EDIT: I'll post a pic when I get home tonight.

As a rule, between 6pm and 8pm, just after tea...it's also known as 'the time to procrastinate on a science forum.'

That's true. It does seem a little pointless when you put it like that. I may as well start a thread with links to a bunch of RSS feeds, and be done with it...there you go, knock yourself out. That sounds like a much better suggestion, I don't think we'll be too hard pressed to find poor sci journalism, there's a veritable ocean of bad articles out there. That's a given on here, isn't it ?

Help wanted with integration along a world line
Royston replied to JohnFromAus's topic in Relativity
These books were suggested by ajb, from another thread, where I was asking about the math behind GR, hope it helps... http://www.scienceforums.net/forum/showpost.php?p=397022&postcount=9 -
I thought the OP was asking whether SR dealt with field equations, AFAIK field equations are not applicable to SR, i.e the field equations I've dealt with are vector expressions of gravity and charge et.c, but I'm yet to study SR in depth, but AFAIK, and what I've scanned through, I can't see any mention to a field with SR, but I might be wrong.

Overuse of 'lol' is a massive turn on for Atheist. <left>I'm the skinny guy on the right, chowing down on some overpriced noodles. This was at a festival last year, where England had the heaviest rain fall in recorded history...the beer wielding, welly stuffed in underpants, handsome chap is LunarTick, who is actually a member on here. The equally handsome chap on the far left is my friend Gav, who's a teacher. The hand in the top left, belongs to my friend Bea, and the guy disguised as a tree in the background was somebody we met randomly, but he does a great impression of a tree. <right> An example as to why you shouldn't stay up till 3 am most nights working on math assignments.

I can imagine that would take some time. The ability to do long division in your head, for example, is redundant these days...not so much a dumbing down, but just completely unnecessary. However, I've actually tried to avoid using Mathcad for my current course, I'm quite enjoying the scribbling of equations onto paper, for some reason. JohnB, I completely symp Not sure if JohnB's comment was solely a joke, or if he does have trouble finishing projects et.c I tend to be the opposite, in that I can't relax until something e.g an assignment is finished, or I've resolved some problem I've been stuck on.

The majority of newsworthy science articles I've posted i.e after the demise of the news sub-forum, tend not to spark much discussion. What discussion there is, if you can all it that, are comments such as 'that's amazing, thanks for sharing', or 'wow, what will science come up with next', or words to that effect. I certainly wouldn't mind the news sub-forum being reintroduced, for a place for informing, rather than debating.

I don't think I'll impress many women with my 4.5" telescope Which has been an ongoing joke in my house. Not my best, but certainly my most concise chat up line, was simply 'hello', it worked for her. I tried the same tactic a few months later, (on somebody else) but she said hello back, and that was a reaction I simply hadn't planned for.
