! Moderator Note I think as the opening statement is false and the rest of the post is word salad that this thread will be locked. This is a philosophy sub-forum - not a "make stuff up as you go along" sub-forum

Funny - that's not really what you said. And many many more identify as independent.

As NY allows voting in specific primary for only voters registered with said party (TTBOMK) and there are twice as many registered Democrats as there are Republican then that makes perfect sense. 5,792,497 2,731,688 [mp][/mp] 0.179 Hillary 0.190 Trump Here are the proportion of registered voters that turned out for the two winners - very similar with Trump just edging it.

This isn't just knocking - but honest advice from someone who many years ago struggled with spelling and grammar but had no trouble with maths. Whenever you are writing, even somewhere as inconsequential as an internet forum, ensure that you don't make sloppy errors in your English. I don't think it is acceptable but people will judge your work in all areas on the basis of your presentation, spelling, and grammar; so get used to demanding precision from yourself in your English as well as your Mathematics from an early age. The more and sooner you get accustomed to checking your text the easier it becomes.

Do the reverse - you have just used simultaneous equations to figure out two numbers. Put the numbers back in where your A and B were and check that it comes out correctly
-
Always but always multiply back out to check whether it is correct

Nah - look at Enthalpy's calculations above. You are talking a 10 metre mirror even at the blue/ultraviolet end of the spectrum to get down to around 1cm resolution (that means that you cannot tell the difference between two lines 1 cm apart and one line). That would be over four times the size of Hubble. There are pictures from KH11 satellites on the Wikipage - they are amazing for a satellite photo but nothing like being able to read news print; or even tell a ford focus from a vauxhall astra. BTW - it will also be doing 20-30000 km/h as well so following the car on the satellite image etc that they do in movies is fairly unlikely (ie hollywood nonsense)

! Moderator Note Although you were specifically warned twice and still thought you should respond to moderation notes - in the interest of the discussion here is the only substantive part of your missing post; the other four paragraphs were bleating about how badly you are treated by the oppressive moderators. It is possible I have missed another post but I don't think so.

Just for you guys enjoying splitting hairs and making digs whilst children die This is Emily Han - who along with her mother Jenny and father Weidong were shot and killed a week or so ago.

That's quite something - I hadn't realised it was so extensive

Bruce Springsteen explaining the cancellation of his recent show Bryan Adams in his press release also cancelling a show In which god-forsaken hell hole are these ageing rockstars (who still really rock) cancelling tour shows because of the recent wave of anti LGBT legislation?

Could you point out the bit - as it is all quite above my head - where the calculation/formula is along the lines of: (Variance in Position of X) and (Variance in Position of Y) are related to some function of Planck's Constant or other constant Cos that is what I would be looking for. What I see is lots of forms and extrapolations of: Variance^2(Difference in position of X1 and X2) and Variance^2(Difference in Momentum of X1 and X2) is related to some function of Planck's constant The first equation is what you have claimed above - the second is what everyone else has been saying.

String - if you do think of the stand https://www.aldi.co.uk/bike-assembly-stand/p/092974007528400 . I not used one but have heard good things

Mini black holes could be a source of energy - Stephen Hawking
imatfaal replied to Moreno's topic in Classical Physics
For all your black hole needs http://xaonon.dyndns.org/hawking/ Change one variable and watch the changes ripple through the others. Small black holes are nasty, hot, and short-lived once you get to the confinement and energy-farming size A trillion tonnes might work - still a hundred million kelvin, lasts practically forever, small enough to be lost on a pinhead. Oh Yeah - forgot to mention the downside; I produce can more power on my pushbike. -
Sirona For the hills you need the gears - although the range of a double at the front is the same as a triple (just larger steps on the double) and doubles are easier to look after and fewer things to go wrong. That bike looks good for the money. But two important things - always but always try a bike before you part with any cash, and ensure that you have a good and easy route to return the bike if something is not right. This often militates against buying a bike over the internet. It is these services which bike shops have to put into their cost - which is why some of the web-shops are so much cheaper. The best of both worlds is a shop with a good high street presence but who sells and thus competes with other web-outlets. Men's and women's saddles are quite different - but most good ones for either sex do have a groove. This is much more important for men than women apparently - but it could just be that research has been done on men's discomfort and none on women's (see mad thread above regarding no need for feminism ) It is important to try saddles out as well - you need the support under the pelvic bones commonly referred to as the sit bones but you don't want support inside this; so you should really buy a saddle of the correct width. If you are getting soreness or joint ache - then getting your bike fitted to your size is crucial. The companies that do this are amazing - but quite pricey - there are do it yourself versions on the web that are a reasonable alternative.

things I used to love are turning feminist
imatfaal replied to Lyudmilascience's topic in The Lounge
Personally I think it is a shame that the Guardian blur out the names of those issuing threats - it is peer group judgment that helps us weigh our actions and publicly enforced anonymity stops the feedback which allows people to realise that their views are far from universal and are deeply disapproved of by friends and family. I always want to be sure that these young men (and they are almost all youngish men) are confronted by their Mums, Sisters, Aunts, and Grannies with a "we need to talk about what you said..." -
"but in this world nothing can be said to be certain but death and taxes" - Ben Franklin who funnily enough lived quite close to me right near my favourite boozer

Are you sure about this bit - we have PAYE in the UK (pay as you earn - a deduction by the employer on the employees behalf so most people never have to do any sums ever) - but you can always elect to make a tax return at the end of the financial year and of course claim any rebate. I make a tax return every year (I am a Company Director so I have to - it is not voluntary) - and can claim back on some of those things above, others are automatically included in my tax code (which how much money before I start paying any tax), and I can claim back for quite a few others not on that list most importantly pension contributions. We pay tax on purchase of stocks - and there is a dividend tax

Come'on String - it is now time to show us your bike! Nice Bike Sirona - that's a similar colour to what I was considering for the next iteration of my commuter (http://spray.bike/products/ - bomber)
-
You are dead right about those stands - can be a right pain and yours looks like a superb hack. You should put it on instructables I would highly recommend buying a work frame - this one was 29 quid off ebay; but you can spend any amount of money more on them. This is my commuter and the bike in the corridor is the same one (as above in my back garden) which used to be orange and is now back in black and white

That maths problem can be done in your head - no problem whatsoever and definitely no complex. Division by 50 is the same as multiplication by 2 and the move the decimal place 2 to the left. Maybe we have different notions of complexity - also possible is that if you learnt some of the techniques of mathematics and science what seems complex and daunting would suddenly become simple and mechanical

No point in skimping on your saddle - that said I buy mine from ebay! I am almost pathologically mean so I will always go for a bargain - I bought up a set of Fizik test saddles for 100 euro from a bike shop that was going out of business in Luxembourg; I now use a Fizik Antares Vs - it also has that groove to stop the numb gonads and also help prevent trouble further back. You should have two main points of contact and they are the ridges of pelvic bone. You don't want any real pressure on anywhere else - especially not on the midline between "ahem" and "ahem" - or as St Augustine would have it no sitting on the stuff "inter faeces et urinam" although that phrase was for something completely different and definitely only really applied to women. High End / Low End. On Victoria Embankment on Friday I overtook a guy (three times - he caught up at traffic lights and then jumped them) on a 10 grand Pinerello - that's not high end that's just silly; if you have a bike that costs as much as a new car then you need to be able to ride it well otherwise it is just embarrassing. I think of bargain as sub-500, low end sub 1000, getting serious below 1500, high end around 2000. For between 500 and 1000 there are some astonishingly good bikes - the french company BTwin 500 series (at Decathlon) is amazing value with a top end bike that is close to the UCI lower weight limit and from all accounts handles brilliantly. Under 500 Halford and Boardman do some amazing deals - the bikes will be a bit nasty but they will do tens of thousands of miles without problem. It is the next level where you are paying for very marginal gains - the difference for instance between Shimano Sora, Tiagra, 105, Ultegra, and Dura Ace is noticeably; but so is the cost 14, 27, 28, 37, 95. For my money 105 in the middle of the range is the best bang for your buck - but any of the middle three are amazing gruppos . It is in this maze that you can make savings by buying components separately - perhaps economising here and splashing out there rather than taking what you are given and of course you get to be silly and have a bike that no one else would be seen dead upon - mainly cos it is the only one

Dry weather and clean rims - no worries. When you are wet through and your rims are covered in a mixture of crap from the road, aluminium dust, brake dust, oil, and water - then maybe. I found a noticeable difference between the rubbish which was supplied, the shimano/ultegra I replaced them with, and again with the swiss-top pro green that I ended up with. I only have rim brakes on my fast bike and I want it to stop as quickly as the tyres will let it I use them throughout the winter they are a brilliant tyre for puncture avoidance- and no, nothing to do with tread for the rain / avoiding aquaplaning. There are two great reasons for heavy tyres in the winter; firstly the water will wash stones/flints/glass into your path and stick it to your tyres; secondly, punctures in the rain are vile. They are quite heavy and wooden though - so for my weekend bike and for the commuter during the summer I switch to Continental GP 4000s II - or Schwalbe Durano plus. These are both much lighter and roll with much less resistance - so much so that you actually will notice a difference. Disc brakes are very easy - they make the rankest amateur able to hit the sweet spot that on rim brakes is very difficult to find. And you are right both the frame and the forks must be designed from the very beginning - you mustn't try to mix and match because the forces and torques are completely different from rim to disc and vice versa That's kinda of what a lot of folks do - however be aware that unless you are aiming high end that you can buy a better bike just off the shelf for the same price. At the high end you can make yourself a real bargain - at the lower end some of the deals available on last seasons bikes or on ebay are just so good that you cannot compete. It is very popular - but there is a loss of range. Two chain rings and ten or eleven at the back are such easy and good quality that you won't find them going wrong much and they are cheap. Tiagra / Apex are just amazing gear sets - and they are at the bottom of the price range!
