First of many no doubt. It amazes me how the teams apparently never seem to know about this kind of thing * or doping etc .

Err - yet again where to begin.

Maybe with a request to a mod to cut these posts to the "games and fun" forum where they belong.

For example the people that claimed to have discovered a gravity wave didn't, but if they can convince everyone they discovered gravity waves (with the added convenience of having every single educational academy agree with you due to confirmation bias and wanting gravity waves to be there) it is a cakewalk for the brainy people getting that grant money.
So what have they discovered. They have set out to observe the stretching of the fabric of space itself. A couple of groups have built similar, but not identical machines at different places on the planet.
Those machines use well known properties of light to measure space along two axes, and they measure quite alot of space (5km or so I think) to a very high degree of accuracy - but the real accuracy comes in the interferometry - despite not knowing exactly how many wavelengths of light fit along each arm, they can tell to very small fractions of a wavelength if those arms change length relative to one another - they are measuring nanometres of change in kilometres of distance (that's 12 orders of magnitude!)

Multiple experiments picked up a signal - the same signal - at the same time.

That is so absurdly unlikely to happen by chance that it is a confirmed discovery. Now since we have a theory of the universe which predicted these waves would exist - we're fairly confident that that is in fact what we have seen.

I think that the noise I can hear at the moment is caused by people in the bar downstairs. If I go downstairs (which I will in a bit) and find an empty bar I shall have to revisit the theory - if I find lots of noisy people, then I'll not.

Why be an actual physicist if you can be a "theoretical physicist" and never actually contribute anything real to the field or need to? I bet the "theoretical" physicists get paid more than the physicists that deal with known facts, its a sick world, where conjecture, confirmation bias and fantasy passes for "facts".

Erm - these guys were experimental physicists. Although they only know what to look for as a result of the work done by theoretical physicists.

You can't propel a rocket in a weightless vacuum the way we get told, the rocket has no air to push against to propel it and it would remain fixed, internally stressing itself, pumping all of the force out in the form of a gas cloud, which indeed, would be moving and yes, with 100% of the force. Don't worry, energy isn't being "lost" here! All of the force is all still there, but it wouldn't move the rocket anywhere, it would effortlessly pump the gas out into the vacuum, where it would float away in "space" for "billions" of years.

A rocket doesn't need air to push against - in your scenario we'd have no satellites, and I can see them quite easily. A rocket pushes against it's own exhaust. What your scenario is losing isn't energy, but momentum.

Space isn't even up there lol, nothing is "floating" and it isn't a vacuum, more of an airless void, but thats technically not a vacuum because lower down there is air and there isn't a barrier to it, I mean you can't have a vacuum connected to a non-vacuum and have it maintain itself, so then what's above us isn't a vacuum, it isn't weightless. Where's the proof apart from stuff shown to us on TV screens? If it is that easy then I guess George Clooney and Sandra Bullock really went into space? They must have because we have the footage on video.

The vacuum of space does have particles in it - The ISS orbits at about 220km, and there are single digits of particles per cc at that altitude. There is no "atmosphere edge", but the atmosphere peters out... the reason for this is gravity, and it's easily observed by taking a barometer and measuring the pressure difference between sea level and the top of a mountain, from that (and lots of points inbetween) you can predict the data for higher and higher altitudes...

It is rocket science but it isn't hard to understand what I just said (in a nutshell it needs air to push on and air isn't there in a vacuum) and this certainly doesn't need maths, it needs understanding - something that is unfortunately completely lacking from the world of mathematics for some reason, I mean when did you ever hear a mathematician admit hey, this entire premise could be wrong?

Actually - Mathematics exists in a pure form, the basic premise of maths are called Axioms - they are assumptions which are made. If you try to make an axiom which is incompatible then you choose which one to discard.
Rockets works by pushing against their exhaust, not the air around them. This is as true for model rockets as it is for Falcon, Soyuz, Saturn 5 etc etc etc. It's also true for ion drives and other low thrust devices. Then you have solar sails, using the momentum of photons, although there is a weird new drive which has some people rather interested. It's not an obvious mechanism - but tests have shown some thrust (although very low levels, virtually within error bars of zero )

Never.

Naive mathematicians that insist on their equations matching reality when they actually don't. Someone needs to tell these people that theories aren't facts because I think they are getting a little bit too carried away with it.

Someone needs to educate you on the meaning of the word theory. And since you didn't listen last time...

"Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality." - Nikola Tesla
Amen to that.
Tesla was referring to a specific group of people who were building things that didn't work.


Rockets work - relativity works - space works.

Putting aside the "cheating" aspect of whats been done here. The tech benefits for motor integration and smaller batteries etc will flow through to road bikes for mere mortals offsetting say performance decline with age. Not for competition use clearly, just everyday cycling. We need to move to making any electrical assist as light and small as is practical for the amount of assist available. So not all negative.

East Coast is mow Virgin. I don't know if they use the same ticketing system. I f not, there are other companies that use it: eg GWR and Chiltern.

presumably it can be appealed? seems an aweful stupid thing to do, like having forbidden drug packets in ones pockets?

Back to Winter weather here on Skye - 25th April

Cycling UK Forum - Touring & Expedition - 26 April 2016 - 7:17pm
Hi folks, just to update any cycling folks with intended tours to Skye & the Western Isles - the weather has reverted back to WINTER.

Snow and hail showers today across Skye with snow and frost forecast over the next few days. Please wrap up and insulate if your camping. No real snow accumulations as such but brief white outs with hail which may scupper people with tight timescales.

Re: Groundeffect Bodybag. Any thoughts and where to buy

Cycling UK Forum - Touring & Expedition - 26 April 2016 - 7:11pm
I've been getting stuff from Ground Effect for years (currently wearing 7 items of their clothing). Delivery is always quick and efficient, but sometimes you get stiffed by Royal Mail/Parcelforce. But even if you have to stump up for customs charges their stuff is still good value.

The only problem with the Bodybag is the length - which isn't a problem for flying but could be an issue on trains. The Tardis is a better size for train travel.

Re: Trailer Loading

DaveP wrote:As earlier advice, put the heaviest stuff at the bottom and as close to the centreline as possible - definitely not all to one side - for very obvious reasons. Put it as far back as possible to reduce the weight on the hitch point. And live with it - there's nothing else to try apart from paying attention to the total load weight.
I currently have both types of trailer and I do find the Yak to be harder work. I'm often conscious of having extra weight to balance, particularly when dis/mounting or pushing. Not so aware when riding, but obviously the bike frame is still seeing these loads.
The yak is obviously better when width might be an issue, and although I haven't tried it I would expect it to be better on really rough ground.
I was surprised to read about your front wheel tending to lift. Yaks mount directly on the axle so shouldn't have this effect,
Unless you mean that it tended to lift if the bike was leant over a bit while pushing... I seem to remember something of the sort happening - the whole rig started to pivot around the rear wheel contact point and the handlebars with the result that the front came off the ground, but sideways. Does that sound about right?

Thats exactly what happens when wheeling around - well described!

Have now got BOB Nutz fitted to mounting points on Surly Troll frame which puts mounting on rear of bike about 30mm higher up and rearwards, but can't see that making a huge difference, will wait and see what happens on Friday when I go shopping!

Hi Sweep, very briefly in answer to your OP, the new inserts are 12mm as opposed to 11mm on the old inserts. I have old rear panniers and new front panniers

I personally haven't had the old inserts pop out. I noticed that Ortlieb claim that the material used on the new inserts will not scuff the racks. Wrong! They do scuff and in my circumstance, the Tara front low loader was badly abraded. I believe that it is because the inserts are 1mm bigger and therefore more slap on them - a term commonly referred to in R&D.

I have followed MartinBrice's idea and fitted the clear plastic tube. The panniers fit a treat. Rattle eliminated. Abrasion eliminated. Possible loss of inserts eliminated. Extended life of panniers racks. The only possible downside is the lack of aesthetic appeal, but that is a small sacrifice given the gains.

I also think the new system is more versatile as regards the different orientations of the fixings, but have to admit that I like the "feel" of the security using the torx screws on the earlier fixings.

I hope this helps.

Thanks for the info MartinBrice.

wow just heard on the 6 0'clock news that a lady cyclist with a name I can't pronounce or spell, has just been banned for having an electric motor and blue tooth switch under her handle bars. I think this was mooted a short time ago here, but not the ban which was then not decided.

any kind of track suit type bottom with elasticated waist? can be smart, I got mine some time ago from M&S - didnt come with a top. Thats all I use now for cycling.
