How the curve calculator works

A very simple, very boring introduction to the curve calculator - however refraction adjustment not included. This is based on the curve calculator from Mick West, but we are ignoring refraction in this video.
follow up videos will be added that include refraction.

A great example of the elegance of a profound mathematical principle. Nicely presented as well. From my schoolboy days:THE SQUAW OF THE HIPPOPOTAMUS A Cherokee Indian chief had 3 wives all of whom were pregnant. When the first squaw gave birth to a boy, the chief was elated and built them a teepee made of buffalo hide. The second squaw also gave birth to a boy a few days later. The chief was extremely happy and built them a teepee of antelope hide. Soon, the third squaw gave birth, but the chief kept the birth details secret. He built them a teepee of hippopotamus hide (I know there are no hippopotami in North America,but just go with it.) He challenged the people of his tribe to guess the latest birth details, and whomever was right would win a fine prize. Many attempted but failed to guess the details. Finally, a young brave came forth and declared that the third squaw had had twins. "That's correct" said the chief."How did you know?" "Simple, " aid the brave. "The value of the squaw of the hippopotamus is equal to the sons of the squaws of the other two hides." I got detention for that!

:It astounds me that flerfers still cling to the 8 inches per mile squared surveyor's shortcut. For starters it is _obviously_ not the formula for a circle (rather a parabola) and secondly, it is the formula for drop, not hidden height, so it is doubly wrong. (3x wrong if you include the fact it was just an estimation in the first place) Actually I take it back. It's not surprising at all that flerfers are clinging to something obviously wrong.

:Remember that in the southern hemisphere you have turn the hypotenuse upsidey down. FECU.

:I have just realised I've forgotten alot since school 😳

:My favorite bald guy teaches my favorite subjects on the internet, my favorite media. Life's good.

:NOT boring at all! When something is EXPLAINED, unlike the flat earther "models" it can be tested and either proven to work, or proven to match reality. Well, it becomes the best model at that point in time. Knowing HOW to calculate things, rather than just throwing stuff into a magic machine and accepting the answers, means that WE can all do the calculations for ourselves and arrive at an answer unaffected by belief. Unless, of course, we choose to NOT believe in mathematics.

:This is great. I wasn't sure about dividing into two channels but I think it will work. This reminded me of a condensed version of fiveredpears stuff.

:FFS where’s Del when you need him? All this Maffs and the great mind of Garden Shed Institute is busy doing a roll up

:Hi CC. This will be really good for nerds like me who like to understand the mechanics. How refreshing after just watching Dels live stream for a laugh....... ravings of a lunatic. Do you think the comments will get spammed by the flearthers denying the math?

:I never even once heard you say ‘angle of attack’ is this real 😆

:Thank you for the conversion in metric.. the way you are explaining reminded me of my math teacher and its why i loved math in school.

:My question is: why is your 80000m distance line a tangent and not the distance on the surface? I was under the assumption that distances on maps are not line of sight based but are adjusted for curvature. Usually flattards use google maps to “measure” distances and google maps surely isn’t line of sight based but uses great circles. So in my eyes those calculations won’t work anyways.

:Like being back in school only this time I want to be and I'm actually paying attention. I'm too old to go ice skating all day now anyway. :D

:Thank you for all your efforts!

:You're left handed, illuminati confirmed.

:It's worth noting as well that flattards have no way of calculating the distance to the horizon on their space biscuit, nor a working explanation of why an horizon forms at all on a flat surface in the first place. (Credit to Cool Hard Logic, testing flattards)

:I always enjoyed the parts of your videos where you whipped out the white board best anyway.

:Great explanation. The 8" x miles-squared formula *can* be used to get an approximation for 'hidden', but it requires a two-step approach. First you need to calculate the distance from the observer to the horizon, using Pythagoras as you show in the video, then use the 8" formula on the distance of the target *beyond* the horizon. For reasonable distances (less than 50 miles, say) this gives a surprisingly good result, because the 'drop' in this case is not very different from the required 'hidden' figure. Taking the figures in the video, the distance of the target beyond the horizon is 74952 metres = 249506 feet = 46.57 miles (all figures approx.) Applying the 8" rule to that gives a 'drop' of 1446 feet = 441 metres, which is very close to the 440 metres for 'hidden' given by the 'proper' method. Of course there is no need to go through this if you have access to a suitable curve calculator!

:My momma always said "Boring is as boring does". This proves (somehow, I'm not quite sure what to look at to prove this statement), your Baldy Catz channel is not boring. Yet. Of course, you haven't done the much needed video "How to count to 1,000,000" yet. That one actually appears to be basically necessary for most flat earthers.

:It would be nice to think that at least a few potential flat earths might watch some of these, and see the error of their ways, but that may just be wishful thinking. Oh by the way, liked and subbed.

:Pythagoras walks into a bar and says "If a right angle triangle has a short side x, a long side y, and an hypotenuse z. Then the sum of z can be calculated by squaring the value of x and the value of...... Urmmmmmm...... ....." The barman says, "Y! The long face". 🙋

:Paper..... Paper..... Very posh school this is. Where's the whiteboard or the blackboard ! Good job yer no a teacher, laddie ? Aye, see when I went tae school..... well if I'd went tae school that is.... 🤡

:That curve calculator sends FEs round the bend.......

:Not boring at all, thanks, good stuff.

:Great educational video Catz. This is just the kind of topic that we should all refresh our memories with, especially when dealing with the word salad of FEers. I've subscribed and I'm looking forward to more. BZ

:Enjoyed it, thanks. So it turns out there is one good thing about FE : it reminds us of the importance of getting basics right. A bit like typhoid and hygiene. More please!

:Your Episode 34 " Oh Dear Nathan ". Pure gold I kept rewinding it. Love the new channel.

:So that answers one question I had Distance to horizon is 5048m from viewpoint. But rest of my questions still stand Nice vid btw

:Clear and simple.

:Oh I beg the heavens to send Dean here with "7.6R". Great vid, Catz, thank you!

:You lost the average flat earther at 40 second's. Nice video Mr Catz.

:Sorry Catz, you have made a serious error. The 8 inches per mile squared is the DROP, NOT the hidden value. The DROP is the SAME as the HIDDEN value if you consider the observer at GROUND level. The DROP does NOT include observer height as a parameter, whereas the HIDDEN value ( which you are calling the lost height I think) does. The 8 inches per mile squared is a VERY ACCURATE approximation for the DROP for well over a 100 miles for distance from observer to target. I did a hangout explaining the concepts 9 months ago on Geostreber's channel LkTQ4Dn8ZAs?t=4377. This same hangout is one in which I analyse the observations of the Isle of Man by Riley and cover issues of observer height etc etc, I will be doing another version of this issue of refraction and the Isle of Man in a hangout very soon on my channel which I think you will find interesting which applies ray tracing to the issue.

:This is what makes you so good. A clear, simple teaching style that makes it a breeze and pleasure to learn. I remember my (1968?)9th grade science teacher taking two days of class to teach this and still, few “got it.” Thanks for the refresher.

:Best left handed handwriting EVER.

:Extremely excited for your new video series!

:Not boring at all, very well explained

:Not boring at all. I find this stuff interesting, even thou I once knew it, your video helps me remember this as well as a couple of others, ie. Pi r squared. I'd forgotten a lot of my "math-from-the-past", as it were.

:I had forgotten the comparison to 8in/m^2 at the end. Glad I rewatched.

:I found that interesting and obvious as to why flat earthers are wrong.

:This wasn't that boring, as I am waking up. Nah, it's fine. This is the first of a long run for Baldy Catz and I am glad to be here.

:All Flat Earthers should make the effort to work out the math in the EXACT same manner as outlined in this video whenever they work out how much an object should be "hidden". They always claim everyone should do the work themselves, and working out the raw math should be considered more reliable than a formula on a webpage.

:Great start to the channel. Have you ever thought about a career in teaching? Lol

:Yup! Boring enough to make me go "woo hoo! ( in my head, at least)" at the end! ^!^

:He doesn't know the radius of earth! So waste of time!

:How I wish you were my teacher

:Ah, So that’s how that Pythagoras thingy works in the real world. 😁💡 Thanks Baldy Catz! 🍎

:Wait, how did you convert from kilometers to meters? You multiplied by 1,000? WRONG! According to a YouTube video I once watched you DIVIDE by 1,000. Duh!

:The squaw on the hippopotamus hide is equal in area to the sons of the squaws on the other two hides.

:Not boring at all. I feel a lot more capable of understanding, and so, explaining, and best of all, ARGUING it now!
