Benvenuti al più ampio studio sulle cadute in arrampicata

0:00:08.745,0:00:10.520
Negli ultimi due anni abbiamo

0:00:10.520,0:00:12.850
misurato e analizzato centinaia di cadute

0:00:12.850,0:00:15.939
Grandi, piccole, con arrampicatori pesanti e leggeri

0:00:15.939,0:00:17.600
e un sacco di attrito

0:00:21.040,0:00:23.620
"Non riesco a fare sicura dinamica così!"

0:00:23.620,0:00:25.719
All'inizio avevo due domante principali

0:00:25.719,0:00:27.320
a cui volevo rispondere

0:00:27.320,0:00:29.319
in questo studio; la prima è

0:00:29.319,0:00:32.919
la quantità di lasco incide sulla caduta?

0:00:32.919,0:00:35.040
Se l'assicuratore dà più corda, ovviamente

0:00:35.040,0:00:37.480
l'arrampicatore farà una caduta più lunga, e se

0:00:37.480,0:00:40.000
cadrà verticalmente la caduta sarà

0:00:40.000,0:00:42.440
più dura perché cadrà di più.

0:00:42.440,0:00:44.849
Tuttavia, nell'arrampicata si verifica spesso

0:00:44.849,0:00:47.070
un piccolo pendolo, una piccola oscillazione

0:00:47.070,0:00:48.960
verso la parete, quindi la domanda è:

0:00:48.960,0:00:51.760
cadere di più riduce questo pendolo?

0:00:51.760,0:00:54.199
Riduce la forza dell'impatto con il quale l'arrampicatore

0:00:54.199,0:00:56.719
colpirà la parete? E la seconda parte dello

0:00:56.719,0:00:59.239
studio cerca di rispondere alla domanda

0:00:59.239,0:01:02.440
"qual è il miglior metodo per assicurare?"

0:01:02.440,0:01:05.760
Compareremo il saltare in alto con

0:01:05.760,0:01:08.920
il fare un passo avanti, e come bonus se cambia

0:01:08.920,0:01:12.040
if the blayer is heavier and as an extra

0:01:12.040,0:01:14.520
bonus we also compared against the tube

0:01:14.520,0:01:16.680
style soft catches where you let the

0:01:16.680,0:01:19.360
Rope slide through the device and while

0:01:19.360,0:01:21.360
my curiosity started with these two

0:01:21.360,0:01:24.040
questions I actually discovered way more

0:01:24.040,0:01:26.759
including some peculiar cases how

0:01:26.759,0:01:30.119
lightweight blayer can cause harder

0:01:30.119,0:01:33.159
catch when a heavier

0:01:33.159,0:01:37.040
blay so let's begin now the problem of

0:01:37.040,0:01:39.880
making such studies is a sheer number of

0:01:39.880,0:01:42.759
variables every fall is different we

0:01:42.759,0:01:44.640
have different weights of the climber

0:01:44.640,0:01:46.960
and the Blair the position of the

0:01:46.960,0:01:50.280
climber before the fall fall height and

0:01:50.280,0:01:52.880
the friction and also the Rope might get

0:01:52.880,0:01:55.600
stiffer over multiple fs and of course

0:01:55.600,0:01:58.159
the big one is how the Blair will handle

0:01:58.159,0:02:01.759
the catch so so I thought okay challenge

0:02:01.759,0:02:03.960
accepted I'm going to put a force

0:02:03.960,0:02:06.600
measuring device on the climber and do

0:02:06.600,0:02:09.200
as many different faults as needed to

0:02:09.200,0:02:12.560
see the patterns and off we went

0:02:12.560,0:02:15.319
measuring and measuring and measuring

0:02:15.319,0:02:17.480
hundred hundreds of Falls and I was

0:02:17.480,0:02:20.400
building a huge database of

0:02:20.400,0:02:23.519
results and after a lot of work I

0:02:23.519,0:02:27.200
understood something and oh [ __ ] moment

0:02:27.200,0:02:29.599
happened what we were actually measuring

0:02:29.599,0:02:31.920
was the peak Force to the climber's

0:02:31.920,0:02:34.920
harness which happens around this moment

0:02:34.920,0:02:37.599
of the Fall however this moment is not a

0:02:37.599,0:02:39.680
problem for the climber what is the

0:02:39.680,0:02:42.599
problem however is how hard the climber

0:02:42.599,0:02:45.440
will hit the wall I always felt sorry

0:02:45.440,0:02:48.120
for these lightweight climbers who are

0:02:48.120,0:02:50.720
slammed into the walls and end up with

0:02:50.720,0:02:53.519
broken or sprained

0:02:53.519,0:02:57.040
ankles so let's fix that now while the

0:02:57.040,0:02:59.400
peak forces should have a correlation

0:02:59.400,0:03:01.560
with how hard the climber will hit the

0:03:01.560,0:03:05.120
wall I needed to find a way to prove it

0:03:05.120,0:03:07.519
and here I was mounting a camera to the

0:03:07.519,0:03:10.080
wall with the hope to calculate the

0:03:10.080,0:03:12.440
speed at which the climber would hit the

0:03:12.440,0:03:15.599
wall based on slow motion footage and

0:03:15.599,0:03:17.680
here was a tricky part due to

0:03:17.680,0:03:19.799
perspective Distortion objects that are

0:03:19.799,0:03:22.680
further away look smaller and in

0:03:22.680,0:03:24.959
addition to that every camera lens

0:03:24.959,0:03:28.120
introduced extra Distortion so I really

0:03:28.120,0:03:30.439
needed to mount the camera as

0:03:30.439,0:03:32.799
perpendicular to the climber's falling

0:03:32.799,0:03:36.080
plane as possible and it's not like I

0:03:36.080,0:03:38.640
can just float the camera anywhere in

0:03:38.640,0:03:41.560
space I want but after a bit of root

0:03:41.560,0:03:44.000
searching and then a lot of object

0:03:44.000,0:03:46.879
tracking combined with a lot of custom

0:03:46.879,0:03:49.560
code I wrote I got these beautiful

0:03:49.560,0:03:51.959
velocity and acceleration

0:03:51.959,0:03:54.879
graphs and now we can do hundreds of

0:03:54.879,0:03:57.920
more fults and make sense of them all

0:03:57.920,0:03:59.920
right let's begin with the question how

0:03:59.920,0:04:02.159
does different amount of slack affect

0:04:02.159,0:04:04.760
the fall what we did was a series of

0:04:04.760,0:04:07.319
incremental Falls where the Blair does

0:04:07.319,0:04:10.560
nothing basically causing a hard catch

0:04:10.560,0:04:13.239
the first fall was with zero slack and

0:04:13.239,0:04:15.760
even though it's a small fall I was

0:04:15.760,0:04:19.880
swung towards the wall really

0:04:20.479,0:04:23.639
hard for the second fall we used about

0:04:23.639,0:04:26.919
half of arm of slack and despite the

0:04:26.919,0:04:29.720
fall being a little bit bigger this time

0:04:29.720,0:04:33.759
the peak horizontal velocity was

0:04:33.759,0:04:36.560
lower now of course on such overhanging

0:04:36.560,0:04:38.880
routes the more the Climber Falls the

0:04:38.880,0:04:41.919
further the wall gets and that's why I

0:04:41.919,0:04:44.600
was measuring horizontal speed and the

0:04:44.600,0:04:46.639
peak of that speed usually happens at

0:04:46.639,0:04:49.080
the bottom of the pendulum and it's a

0:04:49.080,0:04:51.520
very good indicator of what would happen

0:04:51.520,0:04:54.520
if the wall would not be overhanging all

0:04:54.520,0:04:57.600
right let's try with even bigger Falls

0:04:57.600,0:05:02.720
Charlie was clearly enjoying this yeah

0:05:02.720,0:05:05.680
subscribe and the result was interesting

0:05:05.680,0:05:07.759
the horizontal speed was nearly

0:05:07.759,0:05:10.400
identical to the previous fall however

0:05:10.400,0:05:13.160
the peak acceleration was bigger which

0:05:13.160,0:05:15.080
means that the climber would reach the

0:05:15.080,0:05:18.840
peak speed faster so based on this it

0:05:18.840,0:05:21.319
seems that having a little bit of slack

0:05:21.319,0:05:24.720
was better than no slack but having even

0:05:24.720,0:05:26.319
more was

0:05:26.319,0:05:29.039
questionable however despite us trying

0:05:29.039,0:05:31.600
to Mim Mig hard catches these faults

0:05:31.600,0:05:34.960
weren't that hard The Faults were

0:05:34.960,0:05:37.560
relatively small and the blayer was

0:05:37.560,0:05:40.199
still pulled up a lot and the reason I'm

0:05:40.199,0:05:42.360
saying this is that in the past I have

0:05:42.360,0:05:45.160
done similar tests under this bridge

0:05:45.160,0:05:47.520
where I have discovered that once the

0:05:47.520,0:05:50.600
fall is hard enough it exceeds the

0:05:50.600,0:05:53.360
rope's ability to absorb the impact and

0:05:53.360,0:05:56.199
the climber experiences a bounce back

0:05:56.199,0:05:59.639
effect and this causes harder false for

0:05:59.639,0:06:02.680
the climber however when we tried the

0:06:02.680,0:06:05.520
same with soft catches there was no

0:06:05.520,0:06:09.080
bounce back and the swing was

0:06:09.080,0:06:12.280
lower so back to real Rock let's leave

0:06:12.280,0:06:14.599
the hard catches for the reference and

0:06:14.599,0:06:17.520
see how the soft catches will compare

0:06:17.520,0:06:20.360
starting with zero slack we can see that

0:06:20.360,0:06:22.919
the trajectory of the Fall is more

0:06:22.919,0:06:26.000
gradual and that the horizontal speed

0:06:26.000,0:06:29.479
and acceleration was lower significantly

0:06:29.479,0:06:32.479
lower next fall was with half arm of

0:06:32.479,0:06:35.039
slack and despite the climber falling

0:06:35.039,0:06:37.720
more horizontal speed was actually

0:06:37.720,0:06:38.880
almost

0:06:38.880,0:06:43.160
identical so let's try bigger okay

0:06:43.160,0:06:48.639
one two oh okay let's

0:06:48.680,0:06:54.160
go o that was soft don't you think I I

0:06:54.160,0:06:57.039
was too scared to think so despite

0:06:57.039,0:06:59.400
nearly pulling my Blair into the first

0:06:59.400,0:07:02.080
bolt and colliding with him the

0:07:02.080,0:07:05.160
horizontal speed again was nearly

0:07:05.160,0:07:07.800
identical so at least in this test case

0:07:07.800,0:07:10.639
scenario falling more combined with soft

0:07:10.639,0:07:14.879
catch had no benefits but as they say

0:07:14.879,0:07:18.199
one test is no test and that's why I was

0:07:18.199,0:07:20.919
rigging another one in the spot where we

0:07:20.919,0:07:25.599
will be able to do even bigger Falls

0:07:26.080,0:07:29.800
falling hardish so we started with zero

0:07:29.800,0:07:32.280
amount of slack and Charlie giving the

0:07:32.280,0:07:35.680
softest catch he can however the fall

0:07:35.680,0:07:40.000
was described as hard

0:07:41.400,0:07:42.919
dish

0:07:42.919,0:07:48.720
ready yeah one two three

0:07:48.720,0:07:52.240
falling softer and this time adding a

0:07:52.240,0:07:55.240
little bit of slack felt softer for the

0:07:55.240,0:07:57.879
climber and also did reduce the

0:07:57.879,0:08:01.599
horizontal speed by a little bit so

0:08:01.599,0:08:03.680
let's see what happens with even bigger

0:08:03.680,0:08:08.280
Falls you good whenever you want one two

0:08:08.280,0:08:10.039
three

0:08:10.039,0:08:14.400
falling take a big pop very soft very

0:08:14.400,0:08:17.680
soft and if we look into the graphs the

0:08:17.680,0:08:22.039
horizontal speed was even lower this

0:08:22.039,0:08:26.039
time so we went even bigger to 1 and 1

0:08:26.039,0:08:30.000
half M of slack which is quite a lot one

0:08:30.000,0:08:32.240
two three

0:08:32.240,0:08:34.320
falling

0:08:34.320,0:08:36.919
woo that was soft but there was this

0:08:36.919,0:08:41.800
kind of D yeah yeah I I noticed it

0:08:41.800,0:08:44.240
myself so this time the climber felt

0:08:44.240,0:08:47.160
more jerk on the initial impact of the

0:08:47.160,0:08:50.399
Rope however the horizontal speed was

0:08:50.399,0:08:53.440
further reduced and looking into all of

0:08:53.440,0:08:55.519
these faults we can clearly see

0:08:55.519,0:08:58.120
correlation how increasing the amount of

0:08:58.120,0:09:00.519
slack decrease reles the horizontal

0:09:00.519,0:09:02.040
speed into the

0:09:02.040,0:09:04.680
wall and since that was contradicting

0:09:04.680,0:09:07.519
with our previous findings we had to do

0:09:07.519,0:09:10.959
more Falls and in this scenario falling

0:09:10.959,0:09:14.200
more was also better you can even see

0:09:14.200,0:09:16.920
the visual

0:09:21.240,0:09:24.240
difference and here is one more example

0:09:24.240,0:09:26.519
this time the climber was falling from

0:09:26.519,0:09:30.040
lower position and we had less friction

0:09:30.040,0:09:33.120
once again falling more had softer

0:09:33.120,0:09:36.120
impact with the wall so a summary of

0:09:36.120,0:09:38.279
this segment is that the swing or the

0:09:38.279,0:09:41.320
pendulum into the wall can be reduced by

0:09:41.320,0:09:44.800
extra slack however if you exceed R's

0:09:44.800,0:09:47.399
ability to absorb the impact the Rope

0:09:47.399,0:09:49.399
will bounce the climber back into the

0:09:49.399,0:09:53.160
wall and then things might be even worse

0:09:53.160,0:09:56.120
and obviously falling more gets you

0:09:56.120,0:09:59.560
closer to exceeding that limit but more

0:09:59.560,0:10:02.720
importantly hard catch can get you there

0:10:02.720,0:10:05.839
very quickly so for example here is one

0:10:05.839,0:10:08.160
of the most common mistakes where the

0:10:08.160,0:10:11.880
bler simply throws a ton of slack but no

0:10:11.880,0:10:14.240
effort in making a soft

0:10:14.240,0:10:17.240
catch

0:10:21.240,0:10:24.440
okay and here is another one first a

0:10:24.440,0:10:26.399
soft

0:10:26.399,0:10:31.040
catch and now a hard one

0:10:32.040,0:10:35.839
that okay we had the same amount of

0:10:35.839,0:10:40.560
slack but the difference was

0:10:41.959,0:10:44.560
massive you can clearly see the

0:10:44.560,0:10:47.320
bounceback effect how the climber is

0:10:47.320,0:10:49.279
being pulled back

0:10:49.279,0:10:52.440
up what was your

0:10:52.440,0:10:55.560
impressions one elbow versus two elbows

0:10:55.560,0:10:59.440
versus three elbows no elbows between

0:10:59.440,0:11:02.760
one elbow and two you'll have to measure

0:11:02.760,0:11:04.839
that mass masso menos more or less what

0:11:04.839,0:11:07.000
it's going to be but I think that's The

0:11:07.000,0:11:11.279
Sweet Spot how was no slack at all

0:11:11.279,0:11:14.720
difficult to give the soft catch it's

0:11:14.720,0:11:16.480
difficult to give the soft catch yeah

0:11:16.480,0:11:19.959
with no slag is really hard

0:11:19.959,0:11:23.560
to hit the timing perfectly yeah so what

0:11:23.560,0:11:26.600
we all noticed is that with zero slack

0:11:26.600,0:11:28.519
it's really hard to give a soft catch

0:11:28.519,0:11:31.000
because you don't have enough time to go

0:11:31.000,0:11:34.000
down and jump up maybe with the

0:11:34.000,0:11:36.320
exception If the fall is really big then

0:11:36.320,0:11:38.440
the climber is falling for quite a while

0:11:38.440,0:11:40.839
and then you have time but on very very

0:11:40.839,0:11:42.959
small Falls you would have to have some

0:11:42.959,0:11:46.120
cat reflexes and go like super fast but

0:11:46.120,0:11:48.160
in general the most comfortable was

0:11:48.160,0:11:51.120
between half to full arm of slack and

0:11:51.120,0:11:53.200
that caused the softest catches for the

0:11:53.200,0:11:57.120
climbers and more than that is very very

0:11:57.120,0:11:59.600
rarely beneficial and simp simply asking

0:11:59.600,0:12:02.160
for some collisions or dragging the

0:12:02.160,0:12:05.519
blayer into the first bolt or simply a

0:12:05.519,0:12:07.600
bunch of extra Pull-Ups for the climber

0:12:07.600,0:12:10.279
after the fall and uh the bigger ones

0:12:10.279,0:12:12.880
like three elbows like I say between one

0:12:12.880,0:12:15.399
and two elbows is The Sweet Spot like

0:12:15.399,0:12:19.760
one and two is more or less the same for

0:12:19.760,0:12:24.760
me personally three is also softer Anna

0:12:24.760,0:12:28.959
says but just a little bit harder to

0:12:28.959,0:12:31.279
judge again but it's harder to judge

0:12:31.279,0:12:33.760
when to jump mhm the EAS the climber is

0:12:33.760,0:12:36.399
falling faster already exactly exactly

0:12:36.399,0:12:38.399
now I can see how lightweight blers are

0:12:38.399,0:12:40.800
probably already typing no slack for me

0:12:40.800,0:12:43.600
I fly up anyway so we actually did

0:12:43.600,0:12:45.440
testing on that and we got some

0:12:45.440,0:12:48.000
interesting results but before that I

0:12:48.000,0:12:50.320
just wanted to quickly say thank you for

0:12:50.320,0:12:53.160
all my friends and supporters who helped

0:12:53.160,0:12:55.600
in creating all of this study it's been

0:12:55.600,0:12:58.079
the biggest project I've ever tried both

0:12:58.079,0:13:01.480
in terms of time and energy and money so

0:13:01.480,0:13:03.519
it would definitely not be possible

0:13:03.519,0:13:07.000
without all of you so huge thank you and

0:13:07.000,0:13:09.440
now back to lightweight blers so we

0:13:09.440,0:13:12.560
started with zero

0:13:12.560,0:13:15.079
slack wa that looked

0:13:15.079,0:13:19.160
harder yeah visually and we can already

0:13:19.160,0:13:22.160
see something interesting once the robe

0:13:22.160,0:13:24.560
gets tight the speed of the climber

0:13:24.560,0:13:28.279
starts to drop however as soon as the

0:13:28.279,0:13:31.839
blay is pulled off the ground the speed

0:13:31.839,0:13:34.839
of the climber starts to increase again

0:13:34.839,0:13:39.440
the climber experiences a double fall

0:13:41.160,0:13:44.920
effect okay let's increase the amount of

0:13:44.920,0:13:48.160
slack we still get this double fall

0:13:48.160,0:13:51.880
effect but the horizontal speed is

0:13:51.880,0:13:54.160
reduced so let's go

0:13:54.160,0:13:57.560
bigger and here we have the same pattern

0:13:57.560,0:14:00.880
a double fall but the horizontal speed

0:14:00.880,0:14:03.000
is even further

0:14:03.000,0:14:06.120
reduced so let's try even bigger with

0:14:06.120,0:14:09.920
crazy one and a half arms of

0:14:09.920,0:14:16.000
slack you ready yeah three two one soft

0:14:16.000,0:14:19.199
catch and here the double fall effect is

0:14:19.199,0:14:22.079
very visible but same as in previous

0:14:22.079,0:14:24.560
experiments we see a strong correlation

0:14:24.560,0:14:27.320
that the bigger the fall the slower the

0:14:27.320,0:14:30.160
horizontal speed for the climber so the

0:14:30.160,0:14:32.880
softer impact with the wall and while

0:14:32.880,0:14:36.240
that wasn't a surprise what was however

0:14:36.240,0:14:39.800
a surprise is when we swapped her and me

0:14:39.800,0:14:41.720
naturally I was expecting that the

0:14:41.720,0:14:44.480
heavier Blair should cause a harder

0:14:44.480,0:14:47.800
catch for the climber but if we compare

0:14:47.800,0:14:52.720
Anna's no slack versus mine you can see

0:14:52.720,0:14:57.680
that my catch was significantly

0:14:57.680,0:15:00.000
softer

0:15:00.000,0:15:03.759
and here is Anna's half arm of slack

0:15:03.759,0:15:06.600
compared to

0:15:06.720,0:15:10.240
mine and same results my catch was

0:15:10.240,0:15:13.720
softer again and to be fair we were

0:15:13.720,0:15:17.360
asking her to give a soft catch

0:15:17.360,0:15:21.000
one two and give a soft catch you ready

0:15:21.000,0:15:25.480
yeah soft catch on three 2

0:15:27.600,0:15:32.959
1 and finally Anna's full arm of

0:15:32.959,0:15:36.600
slack versus

0:15:37.279,0:15:40.680
mine and to my surprise I was giving

0:15:40.680,0:15:43.480
softer catches for the climber than the

0:15:43.480,0:15:44.480
lighter

0:15:44.480,0:15:47.079
belayer however I think this has more to

0:15:47.079,0:15:49.240
do with the fact that lighter blers

0:15:49.240,0:15:52.000
usually fly up anyway so they don't have

0:15:52.000,0:15:55.639
enough practice to give soft catches but

0:15:55.639,0:15:58.120
let me give you another example so this

0:15:58.120,0:16:02.399
experiment was slightly different 118

0:16:02.399,0:16:05.639
here Me and Charlie did a bunch of soft

0:16:05.639,0:16:08.160
catches but this time we measured the

0:16:08.160,0:16:11.079
forces to the climber this was the

0:16:11.079,0:16:13.920
average line of Charlie's catches this

0:16:13.920,0:16:16.959
was mine and this was the average of

0:16:16.959,0:16:20.240
averages and we also did some hard

0:16:20.240,0:16:23.759
catches for the

0:16:25.120,0:16:28.360
reference that was much harder all right

0:16:28.360,0:16:32.199
and now let's compare this to a light

0:16:32.199,0:16:36.839
Blair no no and the first catch was

0:16:36.839,0:16:41.759
really bad in fact as hard as our heart

0:16:41.759,0:16:44.519
catches you jumped way too soon you've

0:16:44.519,0:16:47.199
got to wait till she sucks you you're

0:16:47.199,0:16:48.720
down here and when you can feel her

0:16:48.720,0:16:52.360
sucking you you push up with

0:16:52.880,0:16:55.519
her look at her once she starts falling

0:16:55.519,0:17:00.480
you go down up I am getting scared

0:17:01.560,0:17:03.680
come

0:17:07.199,0:17:10.679
on no now the second catch was much

0:17:10.679,0:17:14.160
better but still not what we were

0:17:14.160,0:17:18.360
expecting so we did some

0:17:18.360,0:17:22.799
practicing oh that was super soft

0:17:22.959,0:17:27.120
falling and then this

0:17:27.400,0:17:28.919
happened

0:17:28.919,0:17:33.919
that look quite nice 12

0:17:33.919,0:17:36.960
121 so as you can see experience plays a

0:17:36.960,0:17:39.799
bigger role than being lighter and

0:17:39.799,0:17:42.400
although lighter blares very rarely

0:17:42.400,0:17:44.400
cause hard catches for

0:17:44.400,0:17:47.520
climbers however with enough friction

0:17:47.520,0:17:50.280
light Blair becomes heavy and actually

0:17:50.280,0:17:53.120
recently I saw one really nasty fall

0:17:53.120,0:17:55.400
where a bler was a light girl a climber

0:17:55.400,0:17:57.760
was relatively light girl a lot of

0:17:57.760,0:18:02.000
friction and a huge slam into the wall

0:18:02.000,0:18:04.799
and then a poor girl had to get

0:18:04.799,0:18:06.960
assistance to get back to the

0:18:06.960,0:18:10.799
car and I'm curious did you ever got

0:18:10.799,0:18:13.520
unexpectedly hard catch from a light

0:18:13.520,0:18:15.720
blayer write down in the comments I want

0:18:15.720,0:18:18.760
to see how often that happens all right

0:18:18.760,0:18:21.720
so we have seen how both slack and soft

0:18:21.720,0:18:25.320
catch has a big effect on the fall but

0:18:25.320,0:18:28.840
there is something even more important

0:18:28.840,0:18:33.080
here is a hard catch with no

0:18:34.880,0:18:37.720
slack and here is a soft catch with a

0:18:37.720,0:18:40.200
little bit of slack so we can see the

0:18:40.200,0:18:43.720
best and the worst case

0:18:44.000,0:18:47.000
scenarios but now check what happens

0:18:47.000,0:18:49.679
when the Climber Falls from slightly

0:18:49.679,0:18:52.080
different position I simply changed my

0:18:52.080,0:18:56.840
legs but I was not pushing away from the

0:18:57.320,0:19:00.320
wall

0:19:00.370,0:19:02.530
[Music]

0:19:02.530,0:19:04.910
[Laughter]

0:19:04.910,0:19:10.719
[Music]

0:19:11.240,0:19:14.520
I anticipa a bit too much there that's

0:19:14.520,0:19:15.760
why you wear a

0:19:15.760,0:19:18.039
helmet that would have been a what was

0:19:18.039,0:19:20.200
it a trip straight to the yard a trip

0:19:20.200,0:19:23.720
straight to the yard that would be

0:19:23.720,0:19:26.720
go but if we look into the graphs we can

0:19:26.720,0:19:28.840
see that this new fall

0:19:28.840,0:19:32.400
had harder fall than the hard catch

0:19:32.400,0:19:35.000
before despite Charlie trying to give it

0:19:35.000,0:19:37.159
a soft catch with his

0:19:37.159,0:19:40.240
head so as you can see how the Climber

0:19:40.240,0:19:42.320
Falls can be more important than the

0:19:42.320,0:19:46.200
amount of slack or a soft catch and here

0:19:46.200,0:19:48.159
sometimes you can see beginners pushing

0:19:48.159,0:19:51.080
away from the wall during the fall and

0:19:51.080,0:19:53.280
combine that with another inexperienced

0:19:53.280,0:19:55.559
delayer and a hard catch and that's a

0:19:55.559,0:19:59.000
good recipe for sprained ankles so so do

0:19:59.000,0:20:02.480
not push it's very rarely beneficial to

0:20:02.480,0:20:04.520
push away unless you're clearing some

0:20:04.520,0:20:08.840
kind of slab but otherwise do not push

0:20:08.840,0:20:11.080
now in the second part of this study I

0:20:11.080,0:20:13.559
wanted to figure out which blay method

0:20:13.559,0:20:16.840
is the best so we compared jumping up

0:20:16.840,0:20:20.280
versus stepping forward and also does

0:20:20.280,0:20:23.640
that change if the player is heavier or

0:20:23.640,0:20:26.280
there is a lot of friction in the system

0:20:26.280,0:20:28.520
but since all of this is already SL slly

0:20:28.520,0:20:30.600
different topic I'm going to split all

0:20:30.600,0:20:33.960
of this in a part two of this video but

0:20:33.960,0:20:35.559
before you go I wanted to share

0:20:35.559,0:20:37.400
something with you that you might find

0:20:37.400,0:20:39.919
beneficial in order to create these nice

0:20:39.919,0:20:42.000
charts that you have seen in this video

0:20:42.000,0:20:44.320
I needed to understand how to take my

0:20:44.320,0:20:47.200
messy experimental data and perform a

0:20:47.200,0:20:50.600
polom fitting this allows to obtain a

0:20:50.600,0:20:53.720
smooth graph that don't lose important

0:20:53.720,0:20:56.880
points and chances are if you're like me

0:20:56.880,0:20:59.520
math and physics might not be our main

0:20:59.520,0:21:01.799
career path and our abilities to

0:21:01.799,0:21:03.760
understand such topics either never

0:21:03.760,0:21:06.640
existed or are already fading away since

0:21:06.640,0:21:08.760
the last time we sat in calculus or

0:21:08.760,0:21:11.360
physics class and that's why I've been

0:21:11.360,0:21:14.440
really enjoying brilliant.org it's the

0:21:14.440,0:21:17.039
best way to learn math data science and

0:21:17.039,0:21:19.440
computer science interactively in

0:21:19.440,0:21:21.679
general I see two problems of learning

0:21:21.679,0:21:24.559
Advanced topics the first one is not

0:21:24.559,0:21:27.559
having enough building blocks that lead

0:21:27.559,0:21:31.000
into more advanced subjects that's why I

0:21:31.000,0:21:32.679
really love their new feature of

0:21:32.679,0:21:34.880
learning paths where the platform

0:21:34.880,0:21:37.200
progressively guides you from the very

0:21:37.200,0:21:39.919
Basics to more and more complicated and

0:21:39.919,0:21:42.360
interesting topics personally I'm nearly

0:21:42.360,0:21:44.679
done with foundational math and now I

0:21:44.679,0:21:47.279
feel more than ready to dive into data

0:21:47.279,0:21:50.279
science and physics that's my two recent

0:21:50.279,0:21:52.440
interests and the second reason which

0:21:52.440,0:21:54.679
stops us from taking on such learnings

0:21:54.679,0:21:58.720
is that it might feel like oh it might

0:21:58.720,0:22:01.679
take forever to understand these topics

0:22:01.679,0:22:04.600
however just 15 to 20 minutes a day

0:22:04.600,0:22:08.240
equals to 100 hours a year and in 100

0:22:08.240,0:22:10.919
