- Published on Jul 6, 2018
One of the most famous free kicks ever taken - but how far from the goal was Brazil's Roberto Carlos? More links & stuff in full description below ↓↓↓ Discussed by Federico Ardila from San Francisco State University. More Federico videos: http://bit.ly/Federico_Numberphile More football/soccer videos by Numberphile: http://bit.ly/Football_Numberphile The goal was scored by Carlos in a 1-1 drawn between France and Brazil at the Stade de Gerland, Lyon, on 3 June 1997 - it was game one of the "1997 Tournoi de France".

people should apologize for using the imperial system, not the metric one
Never apologize for using SI units. However you are allowed to use any units you like if you can arguing for it.
reading the title i thought it might be about the probability a cross would result in a goal
And now this is in wikipedia. So it is officially an internet fact.
This guy definitely has one of the better handwritings of this channel 😌
I really like this. I especially like the quote he reads at the end, I find it humanizes math (with respect to geometry) somehow. Furthermore, everything in this video is completely testable using simple pictures of landscapes that can be measured after the calculations have been made. I just might try this sometime...
Why don't they show the actual goal, just an animation?
Do not apologize for using metric system, apologize for not determining error bars.
Is it just me or is it cool and refreshing to see real-world measurements incorporated into one of these
Clever way to teach cross ratios.
Belgium won because they watched this.
AGORA O HEXA VEM
I thought this was gonna be about the ratio between angry people and non-angry people in any given population at any given time.
33.13 meters is about 36.23 yards, so whichever source claimed 35 and used the imperial units was more correct than the metric source 😉
PROFESSOR FEDERICO!!! I THINK HE'S JUST SO AWESOME!!
v=3ECoR__tJNQ. You really want to watch the replays, not the live shot.
IT'S COMING HOME
I just counted the number of stripes cut into the grass. 6+6+little.
Pero se va hasta Germania o se baja en la Javeriana?
nice handwriting!
