We've seen lots of crazy skydiving, BASE jumping, wingsuit flying and so on. Now watch Taïg Khris jump from the Eiffel Tower wearing rollerblades. SLYT [turn speakers down if you don't like loud crowds].
Third time lu.... oh. Well, good enough I suppose.
I took my three-year-old son down a slightly smaller version of one of those last week. Even knowing that the element of danger is practically nil, it's still pretty scary sitting at the top. I was all for going down a few mores times, but the boy's instinct for self-preservation kicked in and he wasn't having any of it.

I think you are jaded.
If he jumps out just a fraction too far he breaks his legs. If he lands wrong he breaks his ankles at best. If he jumps out too far and goes off balance mid-air he probably breaks his hip, back or neck.
It's a form of flattery that it looks relatively simple.
If you've ever stood at the top of a 10 meter diving board you'll understand that what it looks like and what it looks like from the top are two very different things.

Also, it looks to me like he's falling over in the second take on purpose, to prepare for hitting the boxes.

Damn, put me in the jaded column.
You know what would have been cool? If he'd stayed on his feet.
You know what would have been cooler still? If instead of polystyrene boxes at the end, there'd been a ramp to flick him back up in the air so that he could use that parachute I was convinced he had (in the first shot) to base jump with.
But you know what would have been even cooler still? Another rhetorical question.

I'm with sodium lights. This had all kinds of why written all over it.
I've never been on rollerblades in my life and the only part of that I couldn't do was have the nerve to assemble thousands of people to watch me not do what they were expecting me to do. Nerf blocks at the end? Really? Why?

Meh. That was a lot less impressive then it sounded. When you read "off the Eiffel tower" you think the top, and you think 'too the ground' not a platform high above the ground. And uh, he doesn't even stick the landing.
Also, while it's true that if he jumped "too far" he could have hurt himself, but how exactly would he have been able to do that? You can only push off with so much force.

It's the gradient. From 30 metres, you don't need much force to jump out another meter or two. At the point because of the gradient he's actually landing considerably further down.

What do you mean by 'gradient' here?
If it was 40 meters to the bottom of the ramp, and he accelerates downward at 9.8m/s2 then you only have 2.9 seconds of fall max.
According to this someone doing a standing long jump (trying to jump as far as they can) can go about 3.5 m/s. So in 2.9 seconds that's just 10 meters. Which is kind of far but this guy is wearing roller blades and he's not trying to jump as far as he can. I think it would be pretty difficult to push off very quickly on accident.
And when you figure in the slope it gets more complicated, since you don't go a full 40 meters before you intercept the slope, it's actually dependent on how fast you're going. You could model it as the intersection of two parabolas (or a parabola and some other curve, whatever), which I'm not going to do.

Delmoi, I'm referring to the gradient of the slope.
The step off he makes looks easy, but isn't. It's not that hard for him to get it wrong, which carries him considerably further down because the tail of comes sharply at the bottom of the slope. Where he hits it in the video is still nearly vertical.
In summary: try it off a 20 meter board at a swimming pool. It's not actually that easy to go *no* distance.

Good thing, because you can't. You need to know where both parabolae are relative to each other, which I don't think is viewable in the video. If he's mounted right above the highest point, then a small change in x is going to be a large change in y. But if he's mounted farther downslope, then small x changes are going to be small(er) y changes.
In fact, this is how they can prevent him from jumping too far. Just have him jump off from an x such that the largest change in x he could reasonably give would still be a safe difference in y. (Holding his distance above the ramp constant.)
Say the equation for the ramp is y = x2. Should we mount him at x = 20 meters? Well, if he jumped out a meter, then the difference would be y(20) - y(19) = 400 - 361 = 39 meters. No. How about at x = 5 meters? y(5) - y(4) = 9 meters. OK.

I'm going into the "meh" column. He seems only slightly more likely to hurt himself than a ski jumper would. Now this is slightly less French, but significantly more badass.

This blog post says 131 feet (39.9 meters) is the height first floor of the Eiffel Tower. Some of the photos on flickr tagged "taigkhris" are a bit more impressive, but none good enough (to my eye) to infer the actual height of the lower platform or the radius of the curve. I tried to find a diagram of the ramp but failed.
It doesn't "look" impressive, I agree. It's intellectually impressive as a world record (highest roller skate jump) , but it doesn't hit me in the gut as impressive. So, a reluctant "meh" from me.
Actually, Tour Eiffel diagram seems to say height of 1st deck is 57.6m (189 feet) so does that mean the floor of the ramp is 17.7 meters off the ground? Would love to have the physics and architecture nerds to weigh in more on this.

- Huge elaborate setup
- Two years of preparation
- Thousands of spectators
...for...
- A guy in rollerblades
- Jumping from the bottom of the tower
- Into cushy padding
- Making only two attempts
- In less than a minute
- Resulting in no obvious success (if he meant to fall, that just makes it even more impressively lame)
- Followed by triumphant jubilation from the guy in rollerblades and no one else

It looks like his ankles are buckling under the weight as he hits the slope. How many g's is he experiencing? I bet if he used old-school roller skates he would have a much better chance of staying upright.

Just to carry on with the spoilsportage, it appears he doesn't jump from the Eiffel Tower. He jumps from a platform constructed in front of the Eiffel Tower, level with the underside of the base arch. You could take the Eiffel Tower away and put it somewhere else and have no effect on the stunt.

Boring. I'm still going to stick with BASE jumping, wingsuit flying and so on. Wait, what if we combined them. Dean Potter may be a dick, but the boy has balls of steel or a nut loose. Jumping off the Eiffel Tower in extremely controlled conditions is one thing, free-soloing a 5.12 with a BASE chute and hoping you don't hit the wall when you accidentally blow a move is another.

How many g's is he experiencing?
Just the one, due to being attracted downwards by the planet.
I think most of his problem was due to having to use a nice smooth slope. The downside of a nice smooth slope that won't burn your pants is that you're going to slide about and fall over.

What about when he hits the ramp?
When you hit a hard surface after a long fall (under 1g), you can experience more than 1g of force because you decelerate very quickly, and F=MA.
So in the context of CynicalKnight's question, I'm afraid you are wrong and being a jerk.

What the fuck? He jumped from the bottom of the tower and slid into a pile of Styrofoam. B.F.D.
First I thought my eyes were playing tricks on me and he was jumping from the top of the Eiffel tower on to a ramp that was on a slightly lower level, and that he was going to use the ramp to do some kind of ski-jump thing off the tower, and then pull a chute. Now THAT would have been cool.

Isn't g a measure of acceleration? I don't disagree the F becomes huge when you decelerate rapidly, but I don't understand what is meant by '1g of force'.
Nevertheless, le morte de bea arthur is correct that there is only 1 'g' of acceleration here.
