My thought was similar - put everything in the box marked nails and screws; but charon has the correct answer quicker than anyone else

That's exactly it. Haven't managed to get it to happen again. Must be a combo of circumstances required. Thanks String

1. segment has a definite meaning in maths - it is the area of a circle defined by a line across the circle (chord) and the edge of the circle (arc); it does not appear that you are using this definition. 2. An obtuse angle is between 90 and 180 degrees - ie between pi/2 and pi radians; one radian does not fall in this range. I am going to say what I understand from yours so far A. Start with a triangle ABC - one edge of which between B and C is N long; call this edge a. The angle opposite it is A. - there are infinitely many triangles like this) B. Change the other two sides (whilst keeping length of side a = N) so that the other two sides b and c also have length =N -you now have a triangle with all three sides equalling N - this triangle is unique. Search on "Equilateral Triangle" - it has three identical sides and three identical angles - each side is N long and each angle is 60 degree or pi/3 radians This is where you have lost me - no angle in that triangle is 1 radian. If you take a circle with radius N - and mark off a distance around the circumference of N you will have an angle of 1 radian. This is not the same as you have done

what is going on here? I tried to reply to this post and for the first time in ages got hijacked to a dodgy "virus removal freephone this number" site

Type 1a are the product of a binary system where the more massive star is slowly fed extra mass - it goes nova at a certain mass (1.44 solar masses); it is this fact that the mass is steady across many examples that allows its use as a standard candle. The peak brightness is very similar across many examples - magnitude 19.3 +/- 0.03. Missing elemental lines and strong elemental lines in the spectra allow us to confirm that a particular signal is a Type 1a (there are two routes to a star system going type 1a but they light emitted is the same) and not a different Type that would have a differing briightness I believe at these scales we assume and believe that the cosmological principle applies - ie that the cosmos is isotropic and homogeneous. Bear in mind this is the scale at which the smallest entities you are bothering with is galactic clusters. If the cosmos were found not to be isotropic and homogeneous at such a scale then serious new thinking would be required. Every so often a team of observers will come up with a variation in some supposed constant depending on which part of the sky they look at - but I do not believe any have been born out in further investigation. There is "dark flow" - but that is still at the confirmatory stage and does not have a good explanation at present if indeed it exists Everything is shifted - the entire emission spectrum; we know (eg from Type 1a SuperNova) what lines are missing and what lines are stronger and this allows us to know both the current wavelength and the original wavelength . For instance what is now the cold microwave background was originally very hot plasma which cooled past the temperature at which photons were continually scattered - we know that temperature and the spectrum that would be emitted and if we stretch it out we can see it "preserved" in the spectrum of the CMB; just as it was predicted many years ago

Dave Davidson has been banned as a sockpuppet of over9000.

Good question and it is not disturbing anyone. Hopefully some stargazers can help you - but I would also recommend getting in touch with your local astronomical society. Most towns have one and they almost all have a list of good purchase telescopes from starter versions for children to spectacular amateur masterpieces. Good luck and great present for the kid!

Nope. 59 less 5 picks (5+4+3+2+1=15) is 44 not 49.

Yes, clearly you need the puzzle explained to you in more detail cos you have failed to grasp it. Firstly that would be a lot of weighings and more importantly you stand a fair chance of not getting an answer*; for instance, if 1 and 12 are swapped then they still weigh 13 and you are none the wiser. And even if you do get an anomaly you might not know if which of your pair is wrong; for instance, if 4&9 weighs 12 then you would not know if 4 had been swapped with 3 or 9 swapped with 8. *In fact I can only think of a small subset of the phase space in which your method could possibly get an answer; if 1&12 weighed 23 then the only change would be 1 swapped for 11 etc.

It is lies and propaganda. You don't honestly think they promote themselves by being honest do you? And since when does "multiculturalism" do anything? It is an idea and approach to living; even its supporters would not be in the business of demonizing any sector of society - because that would suddenly be not-Multiculturalism

I was there - my friend had his skull fractured by a long handled baton wielded by a mounted policeman. I didn't see the car attacked (it was a very large march) - but I was there when we were herded and corralled into Trafalgar Square and then charged by mounted cavalry. Would not happen now - "they" have much better control over demonstrations of public dissent

sorry - Could not resist. John's and Charon's comment pretty much encapsulate the problems with the OP's approach - so I thought I would post one of my fave scientific sillinesses

! Moderator Note Last chance Butch Make a valid attempt to answer questions (not with silly assertions that Saul Perlmutter says it is so) and provide a bit more maths . If we do not see these valid attempts to get into a sensible speculations argument then we will lock the thread. Do not respond to this moderation - Do get with the program and answer questions.

I am a very left wing atheist London-based shipping man - I regularly communicate with rightwing americans, libertarian australians, indian relgious-devotees, polish scientists, belgian students and expats, and all other sorts via this forum. Without the internet my daily conversations would be limited to other london shipping men, family and a few friends with the same thoughts, motivations and prejudices. Whilst the internet can lead to self-reinforcement it is also a much larger base of perspectives than you can get anywhere else; this is much more likely to create variety than uniformity

To an extent I agree - doesn't really apply to me as I ride basically across London twice every day; car do not overtake me! Joking aside very few parts of my journey is my average speed not well in excess of the cars' - those parts in which cars are faster I never see the same car twice as they are doing 50mph. I have raced a black cab whose driver I know from Westminster to Epping and he only caught me up when we got to the country roads well outside London. I understand your point completely though because of those damn slow cyclists on Boris Bikes - every traffic light they either jump the red light or push to the front; meaning every time I have to repass them and stop myself from pushing them off as I overtake I got called "a lanky streak of p!ss" last night - made my day! For someone who at one point couldn't see his shoes cos his belly was in the way this was a fine compliment. My favourite comment at present is "you really need to work on those anger management skills - that level of stress and you clearly don't get any exercise..." I try to stay away from real insults and bad language as I must avoid exacerbating already dangerous situations

Or even no nutbars - just the fear of one and misconception. I have finally made it into a minority - albeit not a particularly oppressed one - got told that as a london cyclist I regularly run red lights, use pavements/sidewalks and hit pedestrians, and scrape cars; and deserve (yes deserve) to end up under a bus. The injustice of it (I am stupidly law-abiding nowadays) made me seethe - and although the stereotyping was of a very minor law-breaker; it made me travel some of the way to understanding the huge burden of unfair judgement we put on people (any group) when we judge all of them as guilty of the worst of the sins of the worst of the group we have (perhaps wrongly and arbitrarily) assigned them to.

I don't think we truly understand the process of collapse - but we do know that there are several intermediate states between material as dense as the atomic matter in the heart of stars, and stuff so dense that it collapses. Neutron stars are one such example - in those the amazing pressure has forced electrons and protons to fuse to form neutrons; ie all you have is neutrons forced into intense closeness. We believe that more pressure will force matter into a quark soup sorta thing. But these intermediate states might be bypassed when a star collapses - we just do not know. Not sure how many atoms there are at the heart of a star - pretty sure everything in there is ionized

It just called the local police and instructed me to remain by the computer. Answering 12 minutes worth of questions I would hope for more than 16 personality types - but was fairly diverting. I think they confused themselves by asking questions in both forms "Do you..." and "Do you think it is best to..." ; and I am willing to bet they did not distinguish. it is very easy to try to make documents such as this test more interesting by varying the way you ask questions - but you must be very careful that you are not changing the question too much

Not this ^ I saw this during the run up to the election and it made a lot of sense I have intervened when women were being overly aggressively hit upon - but only when with a GF/female friend; mainly by getting friend to make eye-contact and inviting the women to join us

Who is being pedantic? Strange made a perfectly valid physics point - atoms have no net charge; your point would stand only if the assertion was that atoms do not have a defined charge. This is fairly unseemly and insulting It is the insistence that a sincere attempt has been made, that hard work has been put in, or that an assertion is the endpoint of many hours of thinking and thus it should be taken with all due seriousness which tends to aggravate an already bad situation. Quantum mechanics is normally a grad-school level course - ie the preparatory work is a physics degree. Much can be gained without that level of study and dedication - but if one has knowledge of only pop-science then to presume to teach those who have done the hard hours of study is hubris.

By the way - if we extend the time period slightly, what is the forum's view on France electing Ms Le Pen as President? Would this act this make it into the reckoning - she is a lot more up front with her racism and bigotry; does that make it more stupid or less?

I think this is the nub of the issue - not so much the fact of Roman numeral for zero but the use of zero per se. We had time telling devices and (to an extent clocks) in Europe for centuries before we really used zero in any meaningful sense

Yes - something in which the slope is indicative - F vs a or F vs x with m and k showing up in the slope. But it is still a nice analogy that proved the point simply and conclusively
