-HOWLING AND MOANING -Day five - I can barely remember | 0:00:02 | 0:00:04 | |
the last time I spoke to another human being. | 0:00:04 | 0:00:06 | |
Wow, Colin is really embracing this wilderness survival thing. | 0:00:06 | 0:00:10 | |
I'm so impressed. Confronting your fears is never an easy thing to do. | 0:00:10 | 0:00:15 | |
Out here in the wild, there could be snakes, mountain lions, | 0:00:15 | 0:00:19 | |
-flies, dogs, rabbits... -HE GASPS | 0:00:19 | 0:00:22 | |
What was that? | 0:00:22 | 0:00:24 | |
Be brave, Jonathan. Be brave. | 0:00:24 | 0:00:26 | |
-BELL RINGS -Well, the show must go on. | 0:00:26 | 0:00:29 | |
We are going live, Professor. | 0:00:29 | 0:00:31 | |
Hey, wait for me! | 0:00:31 | 0:00:33 | |
ANNOUNCER: This is... | 0:00:33 | 0:00:35 | |
With... | 0:00:35 | 0:00:37 | |
..the floor manager. | 0:00:41 | 0:00:44 | |
And... | 0:00:44 | 0:00:46 | |
Stand by! | 0:00:46 | 0:00:48 | |
Come on, everybody! | 0:00:48 | 0:00:50 | |
-BOTH: -It's time for... | 0:00:53 | 0:00:55 | |
Today, we are asking... | 0:00:57 | 0:00:59 | |
Did you know that the Earth isn't perfectly round? | 0:01:01 | 0:01:04 | |
In fact, its circumference is around 67km less measured vertically, | 0:01:04 | 0:01:08 | |
going through the poles, than it is around the equator. | 0:01:08 | 0:01:12 | |
I always thought it was flat. | 0:01:12 | 0:01:14 | |
So tell us, Dr Knowles, how long would it take to walk around | 0:01:14 | 0:01:18 | |
this not-quite-round Earth of yours? | 0:01:18 | 0:01:20 | |
If we allow for eight hours' rest per day, | 0:01:20 | 0:01:22 | |
walk only in a straight line | 0:01:22 | 0:01:24 | |
and assume a constant speed of about 5km per hour, | 0:01:24 | 0:01:27 | |
it would take a person about 500 days to walk the distance of | 0:01:27 | 0:01:30 | |
the Earth's equator. | 0:01:30 | 0:01:32 | |
Hmm. But that doesn't take into account mountains, | 0:01:32 | 0:01:35 | |
deserts, oceans, jungles... | 0:01:35 | 0:01:37 | |
I'm not sure if it's possible to | 0:01:37 | 0:01:39 | |
accurately calculate this one, Professor. | 0:01:39 | 0:01:41 | |
Here's an idea. | 0:01:41 | 0:01:42 | |
Why don't we take a quick break while Dr Knowles figures out | 0:01:42 | 0:01:45 | |
a better way of answering the question? Heh! | 0:01:45 | 0:01:48 | |
HOWLING | 0:01:51 | 0:01:53 | |
Whatever is out there, whatever is making that noise, | 0:01:53 | 0:01:56 | |
it's planning to have me for dinner. | 0:01:56 | 0:01:58 | |
-Oooooh! -Owwwww! | 0:01:58 | 0:02:00 | |
-Oogie-boogie-boogie-boogie. -Ow-owww! | 0:02:00 | 0:02:02 | |
Ms Hucklebuck, can we stop doing this now? | 0:02:02 | 0:02:05 | |
My arms are really tired. | 0:02:05 | 0:02:07 | |
Yes, I think that just about covers frights and terrors in the wild. | 0:02:07 | 0:02:11 | |
You can stop now. | 0:02:11 | 0:02:13 | |
-Yes, nailed it. -BELL RINGS | 0:02:13 | 0:02:15 | |
Ooh! Positions, everyone! | 0:02:15 | 0:02:16 | |
So tell us, Dr Knowles, if there were | 0:02:22 | 0:02:24 | |
no mountains or barriers or anything, and if you never | 0:02:24 | 0:02:27 | |
needed to take a rest, how long would it take to walk the Earth? | 0:02:27 | 0:02:30 | |
Well, in this hypothetical situation, | 0:02:30 | 0:02:33 | |
and assuming a constant speed, it would take an average human | 0:02:33 | 0:02:37 | |
around 335 days to walk | 0:02:37 | 0:02:39 | |
the Earth's equator. Just under a year. | 0:02:39 | 0:02:41 | |
At the speed of a crawling baby, | 0:02:41 | 0:02:43 | |
it would take two years and four months. | 0:02:43 | 0:02:46 | |
But that seems fast compared to the giant tortoise, | 0:02:46 | 0:02:49 | |
which would take over 76 years to complete the journey. | 0:02:49 | 0:02:53 | |
Dr Knowles, I wonder what | 0:02:58 | 0:03:00 | |
the fastest way to go around the Earth would be. | 0:03:00 | 0:03:02 | |
Based on top speed alone, the fastest way to travel around | 0:03:02 | 0:03:05 | |
the Earth would be in a North American X-15 rocket plane | 0:03:05 | 0:03:08 | |
in just over five-and-a-half hours. | 0:03:08 | 0:03:11 | |
PLANE ENGINE ROARS | 0:03:11 | 0:03:12 | |
See you next time! | 0:03:12 | 0:03:14 | |
And we are clear. | 0:03:14 | 0:03:17 | |
OK, Colin. Training's over. | 0:03:17 | 0:03:19 | |
You can come out now. | 0:03:19 | 0:03:20 | |
Yes! Civilisation at last! | 0:03:20 | 0:03:23 | |
Well done, Jonathan. | 0:03:23 | 0:03:25 | |
You scored full marks | 0:03:25 | 0:03:26 | |
on wilderness survival training level one. | 0:03:26 | 0:03:29 | |
Level one? | 0:03:29 | 0:03:31 | |
Oh, Colin, you are going to love level two - | 0:03:31 | 0:03:33 | |
a three-day hike to Monster Mountain. | 0:03:33 | 0:03:36 | |
-Raaaaar! -Ahhh! | 0:03:36 | 0:03:38 | |
I-I-I-I think I've reached my desired wilderness level for now, | 0:03:38 | 0:03:41 | |
thank you very much. B-B-Bye-bye. | 0:03:41 | 0:03:44 | |
Oh, dear, I hope we didn't scare him too much. | 0:03:44 | 0:03:47 | |
Maybe level two could just be camping in the back garden. | 0:03:47 | 0:03:50 | |
Or sleeping with the lights off. | 0:03:50 | 0:03:52 | |
Good idea. One step at a time. | 0:03:52 | 0:03:55 |
