When airplanes are travelling virtually direct to a destination from the uk to north america are you fying around the curvature of the earth as most of the time you appear to be flying dead straight on a specific heading. on a globe you would appear to be following the curvature of earth. i havent had explained quite properly to me.
your calculation has some wired random.and it doesnt work on earth,if the shadows dont go over the horizon line;and you cant work with triangle,because one side of it is curved.there is a possibility to calculate a sector of a circle,but you need the radius.i looked around and i didn´t found a mathematic possibility to find out how much the surface is curved(nothing like curve-angle).and by the way all flat models have a orbiting sun,like a spotlight above a stage.so that´s not realy a disprove
((I erased my own comment by mistake..)) As I was saying -- I wasn't sure how, but I checked, and I am not qualifying yet (I need "thousands of viewers" on my videos ;)
I explained this part in the blog (too long to get into in the vid) -- the measurement of the fruit is fruitless (pun intended), because the pummelo wasn't round and had varying radii.
And about the fruit name, well, the sticker on it said "Red Pummelo".. I follow instructions :P I probably is a pink grapefruit, I have no idea how to call it in English other than what the sticker said... ;)
Interesting - I googled for red pommelo and found at thefruitpages that "Pummelo, the father of the grapefruit;" - so they differ somehow. Even an approximate measure would have strengthened the video. Maybe do it on a beach ball *pop* or how about a sphere of Styrofoam?
I did measure, and it came out SO FAR AWAY from the result (about 37 cm I think), that I really didn't think it was relevant to show, because then I would have to add why the measurement isn't accurate in the fruit but is more accurate in the earth, etc... I added a section about that in the Blog though, figured there would be questions about it :)
It's a good point, but I couldn't find a perfectly round (or.. "more round") fruit.
Ah. Yes, reporting results that merely reveal the limits of the method is not good. I agree, a watermelon, measured around the axis might be good, but you'll have to throw a party afterwards! (The Annual WaterMellon Measuring Contest and Party ;-)
No no I didn't mean I shouldn't report the results, that's not scientific :) I just meant that in the video itself I had to choose what to show, due to time constraints. I built the blog specifically for that, though.
But the experiment this time wasnt meant to actually show that the method is accurate in MEASURING (its not) it was meant to show that it's accurate in showing the Earth is round, which it did show, and close to finding an estimate of the circumference. I will correct the blog...
Yeah that's why I said "not exactly above the equator" / "we will discuss this in another video"... I had to pick and choose what to talk about, or I'd just go on and on and on on a never-ending rant :)
And yeah, the battery fruit thing is cool too. I might do that too at some point :)
@4:40 you can see that there is a smiley face on the fruit :)

your videos are very interesting, but they are too, too, too, too...
what was I saying? oh, yeah, too long
maybe you could make 2 versions. the short and amazing one AND the long and interesting one
keep doin' it great!

@ElementSkater036: Hah! You're right, she sounds a very tiny bit like Walken.

Some people still believe the earth is flat. Shame lol.

Hey, this is really cool!
Never thought I'd see an educational video on YouTube, but this is great.

Nice lead-in cartoon! It would have helped if you actually measured the size of the fruit.
(Looks like a 'pink grapefruit' to me by the way.)

The sun's directly above the Tropic of Cancer on the summer solstice.
Also, if you had used a copper nail and a zinc nail, you could have used your fruit to power your "sun." :-)
