Want to help analyze high speed data? Domino Data Entry

I fully expected there to be many videos left to analyse at this point. This group of patreons is awesome!

Agreed, or at least post a 2nd, 3rd, 4th, etc. to Google Docs. I just read the email and was happy to participate, but everything was already done. Galaxy Zoo crowdsources data from as many people as possible and compares the results to confirm the inputs and to rule out anomalies (<a href="https://www.galaxyzoo.org/)." rel="nofollow noopener" target="_blank">https://www.galaxyzoo.org/).</a> Couldn't hurt.

I also noticed that some of them have a single collision and then the initial one slides down the next one. Other have multiple collisions. Usually the first at the top and then a second at like a quarter of the way down. This seems to happen later down the line.

Not what I expected to do either but it was kinda fun. :)

Looking back I think I misused the twist label a bit :p but I guess the frame number is more important anyway

Also, good questions in the comments here around the "how" of the data gathering &amp; recording. Be sure to note the particulars if you do post to Reddit. Just my two cents bud! :)

/r/Crowdsourcing/ there's a subreddit for this kind of project/request Destin. Could cross-post there &amp; on your /r/SmarterEveryDay/ - would see this frame counting task done lickity-split (never underestimate the number of bored redditors). At this point I suggest posting/linking to a 2nd copy of the spreadsheet out there so you can compare the Patreon posted version with the Reddit posted one, and do secondary validation on any differences. That way you reduce the human error factor. The numbers need to be right for the statistical analysis to be right.

I didn't plan to spend nearly two hours looking at less than 1 second of footage, but it was fun. Let's do this again soon!

I did the same. As soon as there was perceptible movement, I stepped back one frame. So at least our observations will be consistent with each other. :)

Where it's clear I'm trying to note the frame where the movement of the preceding domino stopped, but they apparently refused to always line up on 0.1ms boundaries.

yeah i see what you mean. they're rattling back and forth. 1 will hit 2, 2 will hit 3, 2 will bounce back and hit 1 then bounce forward and hit 3 again right as 3 is hitting 4.

also: i've been counting a strike as the frame before the next domino moves. i figure if i see any movement then the dominos have already touched and one is moving the other. so the frame right before should be the closest the previous domino is to the next one.

Everfalling

Sheet #9 needs the colors corrected, they don't quite match video #9. Also I'm noticing that a good number of dominoes made double impacts, the one in video 9 at frame 1839 for instance basically has two dominoes near-simultaneously pushing the next one.

Well i at least got one done. Now it's time for bed.

Andrew Young

also twist seems to go on the domino actively twisting before striking. so between red and orange if the red is twisting as a result of the red before it such that the twisting hits the orange then that last red gets a twist label.

Everfalling

help. i'm editing #19 and it stopped letting me edit cells. i can edit cells on other tabs if i want but not on #19. i donno why,

Everfalling

That's not what I expected to do tonight. Reminded me of data capture and analysis from physics class, oh the memories.

I think so :) that's how Destin did it for Video 1

Mark

For clarification: when the last red domino hits the first orange domino, we put this entry in the last red row of the spreadsheet, right? So in the column of the domino doing the hitting, not being hit.

Austin Burnham

I filled in tab 2, but its' locked for saving.

Patrick Ford

I'm unable to edit the spreadsheet

Oooo... can't tell you how much I would love to do this (software engineer doing flight controls)....but work is busy and we've got a newborn at home!
