Using Math to Skate On Thin Ice

People get nervous when they see Märten Ajne ice skating. He intentionally skates on extremely thin ice. Ajne has pursued this dangerous hobby for 40 years and has skated on more than 1,800 bodies of water from Norway to North America. He uses his knowledge as a mathematician and a highly-trained ear to stay safe. Ajne can actually calculate how thick the ice is by listening to the sound it makes when he glides across it. Join us for one of the coolest math lessons ever taught.

@@jonasthemovie I feel like you must have misunderstood both comments. OP was pointing out that Norway was mentioned by name, despite the guy having only skated on a couple of lakes there, while he has skated on hundreds in Sweden. Additionally, the map is centered on Sweden, so why was Norway the country mentioned by name in the narration? Shouldn't it have been Sweden that was mentioned? Hope that clears things up.

@dennisg.8618 4 года назад

When I lived in Maine I use to do this on rivers. The middle would be flowing water and frozen along the edges of the river , stream. Ice would freeze over the rocks made natural ramps. On the stream I would jump over the unfrozen part. One time I jumped the middle and when I landed on the other side one leg went through the ice up to my knee. My momentum nearly snapped my knee over like a chicken leg. It hurt for a long time.

I went on ice as thin as 1.5" or 38mm when I was a kid and about 120 lbs. I was cracking, but still supported well. It was a river, so I stayed rather close to shore where I had shoveled an area. Not the smartest thing to do, but I remember it well.

@virg0h 4 года назад

he knows how thin the ice is by hearing the pitches whilst he skates, for an example hearing a highest pitch means the ice is 3cm which is as thin as it gets before it finally cracks

@virg0h 4 года назад

he uses coincidence frequency (when a vibration is sufficiently achieved to the wavelength of the ice so it’s equivalent to the wavelength in the air)

2:06 They got Sweden and Norway mixed up. He's been skating very much in Sweden but not at all in Norway according to the map, yet the voiceover said "Norway". He's from Sweden. Also, in the description, his name is spelt wrong. He's called Mårten, but it's written 'Märten' there. Mårten is a common Swedish name, Märten isn't a real name. Yes, there is a difference between Å and Ä.
