I've shown you what the globe model is about here and I've demonstrated why Bev's 50 metre tests are pointless because standing in the middle of two risers on the globe at 50 metres from each end will not show any discernable drop. Your side on the other hand can be quoted saying, "it's horizontal all the way across", over a mile but refuse to test anywhere that is not the middle of 2 nearby risers. I can absolutely guarantee you that Bev will not carry out a test over any meaningful distance where he is not standing in the middle of 2 risers. All this should be setting off alarm bells but cog dis is real and I fully expect you to dismiss every aspect of my presentation. This was geometry and all results came from that geometry. I'd like to say that we can use a sphere to model reality but you'll just obfuscate and spend several hours saying the Earth is not a sphere with a perfectly smooth surface etc. We know and quit being so predictable! A model can be as detailed or as simple as you want and a model based on a sphere produces results that match reality very accurately. We could go further and base it on an oblate spheroid but why complicate it any more than it needs to be when a sphere gives adequate and accurate results? Nothing I can say or do can snap you out of your fiction. Only you can carry out the tests and analyse the results. If you stand at riser 1 with your auto level and observe no drop over mile then horizontal world rules and you can collect your Nobel Prize. But if you do observe drop and that drop matches predictions made from globe models, well, you can either be welcomed to globe or let your cog dis rule your thinking and you can stay a Horizontal Earther if that makes you feel warm and fuzzy inside. So what you waiting for, prove the ballers wrong!

Ай бұрын
@@Elder-Bear The geometry is there if you want to follow it. You guys are supposed to be all about the geometry so focus on that. The curved line was a circle with a radius value of 6371000. Usually I'd use km for the mean radius of Earth but this time I used metres. The grey tubes were 2.1 metres tall, they all diverge from each other and are all perpendicular to the curve. The tubes were all filled to a level of 1.8 metres each. The scale is important. I've used 150:1. This means I have compressed the xAxis in order fit everything in to one screen. Changing the scale does not affect the measurements shown in the table. GeoGebra will measure the drops as if it is 1:1. However, making it 150:1 might give it a somewhat squashed look but that is necessary if we're going to see 16 tubes spanning almost a mile while at the same time discern drops that are measured in millimetres with our eyes. Now I know you don't believe science but gravity is a thing. So in this model, straight down from any point on the curve will reach the centre of the circle. Straight up for any point on the circle is along the line that joins that point with the centre. This is why the tubes can diverge from each other but at the same time remain vertical. Think of the Earth as a really big ball! Now this geometry makes predictions as to what you'll measure and it's all based on the this really big ball having an atmosphere. Refraction is also a thing so it needs to be taken into consideration which I have done. Now I know you're not globers over at OTL because Bev says as much. If you're wanting to get to the truth then you're going to have to devise tests that will discover the curvature. The current test of standing between 2 nearby water levels won't cut it and I have shown you why. Yes, your side.

Excellent analysis showing that Bev is assuming level is exactly the same as horizontal. Now over short distances this does appear to be the case since, as you showed @ 7:00, the calculated curvature drop for 50 meters is a miniscule 0.196 mm and how would you measure this because an auto-level’s horizontal reference is not perfectly horizontal. A top-of-the-line auto-level has an accuracy of about ± 0.8 mm @ 30 meters (1/32 inch @ 100ft) so this would be ± 1.3 mm @ 50 meters which is much larger than the 0.196 mm curvature drop for that distance. This is why accurate differential leveling requires that the BS and FS are balanced (the same distance) since this eliminates instrument, curvature and refraction errors. The funny thing is that Bev has measured curvature drop when he set an auto-level up 1.2 meters above the beach near Southport, about 19 km south of Blackpool. The crosshairs are targeting distant Blackpool Tower where the steel tower connects to the roof of the brick building and this is 30+ meters above his auto-level’s elevation. Of course, Bev has a lot of excuses as to why we should ignore what we see. Would you mind if I use a few parts of your video since I might make a video expanding on what you presented?

Cheers and help yourself. Yeah, I've seen the photo when watching a bluemarblescience video he did on Bev and that Southport/Blackpool observation. I know both places very well and have even worked in the Tower Building for a few weeks many years ago. Like Bev, I haven't got much of a clue about surveying or the fieldwork 🤣but if I was him I wouldn't bother with water levels. Far better to do it the way Bob the science guy did it across the lake in his back yard, using poles at various points and set distances. While I accounted for refraction in this video I didn't account for instrument or user errors like you point out. While I'd like to learn about that more for myself, I didn't see any need to complicate it any further. What's good about this geometry is Bev can open it up in his own app and play with it but we know he won't. He can use it to double a distance and see the drop is x4 the unit drop. Treble it, the drop is now x9. Quadruple it, the drop is now x16.... x25.... x36 etc I should have mentioned something like that but I don't like videos going on too long. He can definitely observe this reality. I love your videos. They're always very informative and I always learn something. 👍

Just a side thought... If we have a water level located along the surface of the Earth, covering a distance between endpoints of, say 100 km. Assuming an unsealed tube, wouldn't there be an effect do to any differences in atmospheric pressure between the two ends? I'm pointing this out only as an example of how we need to be aware of factors affecting our measurements. We can then determine how large an effect they may have, and take them into account. Bev doesn't seem to do that very well, while you do.

Good point about atmospheric pressure. There are other factors that would have to be considered as well. For a small pipe, something like a garden hose, and a very long run, surface friction might actually come into play. Also on short runs the surface tension of the water against the edge of the tube would lead to unreliable readings. Another practical issue is the filling of a long pipe without getting bubbles trapped in it. As a "thought experiment" for discussion purposes, we can set these aside. But to actually carry out this experiment they and other problems would have to be resolved.

Also, as i understand Bernoulli's law it would also cause a pressure differential if there's going wind over one end and but not over the oither. I didn't calculate the actual sensiviry against these factors, so I might as well overestimate them. But if I'm right, wouldn't that make the use of such devices over several kilometers impractical?

Yes, I think there are a number of "real world" factors that would make such an experiment very difficult to carry out. For example, if using something like a garden hose, over a distance of kilometers, friction within the pipe might have a significant effect. Even the surface tension at the ends of the pipe, where we would want to take the level reading, could pose problems. Over shorter distances that surface tension would cause the water to rise up the sides of the pipe more than the Earth curvature we would expect to see. Over long distances it would be hard to fill the pipe without bubbles getting trapped in it and hard to verify that no bubbles were indeed trapped. There are probably many more complications.

By the way, the 'Bedford Levels' are not particularly close to Bedford, they're some 30-50miles east, in Cambridgeshire. The stretch that everyone gets excited about is part of the 'Hundred Foot Drain', which in turn has nothing to do with its physical dimensions, any more than the 'Sixteen Foot Drain'. The Drain runs from the River Great Ouse at Earith, generally north-eastwards to rejoin the Great Ouse again near Downham Market, and on to the sea at King's Lynn. The particular stretch runs from just north west of Ely, past Welney, & almost as far as Downham Market, dead straight for about 10 miles. The drains were dug in the 17th Century by Dutch engineers, to drain the Fens to create farmland. An earlier project had been carried out to drain land under the orders of the Duke of Bedford, whose land it was. Some years ago, I used to do seasonal driving work for courier companies, and explored most parts around there. It is indeed very flat, in terms of land, although the roads certainly aren't, and often run perilously close alongside the drains for long distances, with nothing between you and the water but a very steep downward bank. At least one or two cars are pulled out of the water each year.

Another nice video Petey. But I have one small criticism. It seems you've made all the vertical tubes 'vertical' and parallel to each other. I think they should be perpendicular to the green 'surface'. And so the angle of the 'string' stretched between A and B would 'dip' and not be perfectly perpendicular at each end, only perpendicular to the tube at the midpoint.
@Petey194

Thanks Mike. I think it just looks that way. I can assure you that they all do project to the origin and are not parallel to each other. Maybe it looks that way because I used (xAxis 150 : 1 yAxis) which doesn't change the result. I don't think I made that clear enough to be fair. There was a little graphic on screen top right at the beginning. I think the string is ok too. There is dip there at both ends. I did check some of the angles against WB's advanced curve calculator to ensure the geometry gave the right results. Maybe you can double check. I used 0.17 as the refraction coefficient and 1.8 metres for the observer and target heights.

That illustrates perfectly why scale matters. If the vertical lines were extended the angles to each other would be more pronounced.

Just to add a bit about the geometry. I used Polar Coordinates to create the points F and T. That's the Bases and Tops of each tube. You can create a point for any angle (α) at any radius (r) like so: (r; α). If I was to create another point (r+h; α) where (h) is the height and join those 2 points with a segment then that segment would be perpendicular to a circle with radius (r). eg, If I have a circle with radius 10 and a line connecting point (10;45°) and point (13;45°), then that line would go through the origin.

" All points of a water level will be at equal altitude...... ". According to my understanding, the water level knows Jack Sh£t about altitudes. It is an adaptation of a simple 'U' tube manometer. Both ends are open to atmospheric pressure. As we all know, we can change the level in the limbs by gently blowing into, or sucking on one of the limbs. Inserting 'T' joints, to make extra limbs doesn't change that. When you break it down to its fundamentals, it features 'g', gravity, because the weight of liquid, or the volume & density feature. Where the pressure on each limb differs, the weight of liquid in the column of liquid of the height difference enters the calculation of relative pressure. Under most practical applications, the two limbs will be geographically close, and atmospheric pressure can be assumed to be identical - hence the observed effect. The liquid in the tubes 'knows' nothing about the ground around or below it. Nor does it 'know' what is happening at the 'other' end of the tube, it is merely responding to the forces acting upon it, atmospheric pressure & gravity. If we constructed a level where the 2 limbs are separated far enough as to be in different atmospheric regions, the 'height' of liquid in the two limbs will not be the same. This would probably require a distance of several miles, unless there was a tornado in the vicinity, and, if there's a tornado nearby, I'm not hanging around to conduct silly schoolboy physics experiments.

Shame his followers refuse to acknowledge that argument.

Bev wouldn't believe any results outside the documented tool limit that guarantees sub mm accuracy. That is the reason He gave for dismissing the implication of the shot his team took on the beach looking at Bev through an autolevel with Blackpool tower far in the background. As for sighting along the full length of his "realizing Euclid" stunt at the Bedford level, he never thought of it as that stretch of canal had a slight bend in it with a big tree at the bend obscuring the view along that bank between the two ends of the canal. Bev's use of the autolevel midway between the water level risers is classic technique for transferring an elevation over long distances with the risers acting as the measuring rod. It works equally well for both flat and globe. From what I have witnessed I'd say Bev is a waste of time. He acts as if he has severe memory issues and seems incapable of departing from his well worn ruts.

Excellent presentation, Petey. By breaking the distance into smaller "blocks" where the drop is negligibly small, he's effectively - and knowingly IMO - reducing the overall 1.6mm (or whatever it was) into fractions of that amount at the intermediate points. Bad faith if ever I saw it.
