All right, so how do you think you did? 00:00:00
Well, your mathematical computations and reasoning are going to be important skills to answering 00:00:02
the questions. 00:00:06
And speaking of questions, here with me now to answer some student questions are Dick 00:00:07
and Hugh. 00:00:11
So let's go to Washington, D.C., and meet up with a group of students from 14 schools 00:00:12
that are spending a day with their adoptive business partner, the FAA, in a special event 00:00:16
recognizing the 95th anniversary of the Wright Brothers' first flight. 00:00:21
On the stage, we have some important leaders to our country in transportation research, 00:00:25
and I'd like to take a moment to introduce our viewers to them. 00:00:29
First, we have Mr. Rodney Slater, Secretary of the Department of Transportation. 00:00:33
We also have Mrs. Jane Garvey, who is the head of the FAA. 00:00:39
And we have Mr. Daniel Golden, the head of NASA, who also has a very special message 00:00:44
for our viewers. 00:00:49
Mr. Golden. 00:00:50
Hi, Mr. Golden. 00:00:51
Hi, Mr. Golden. 00:00:52
I understand you have some words for us, for our viewers. 00:00:53
Yes. 00:00:56
I hope all the students here in Washington and around the country, 700,000 of them, see 00:00:57
the kind of tools we use at the FAA to make planes fly safer, at NASA to send the shuttle 00:01:05
into space, and they understand that these are real tools and they're going to learn 00:01:11
how to use them. 00:01:16
And they also understand that if they understand how to use these tools, they'll have good 00:01:17
jobs when they grow up, and they'll be able to lead our country. 00:01:22
Mr. Golden, thank you. 00:01:27
Those are very good words for our viewers. 00:01:28
And now, beside Secretary Slater and Mrs. Garvey, is a student whom they will introduce. 00:01:30
They will have a question for our researchers back here in the studio. 00:01:35
So, Mr. Slater, will you introduce your guest, please? 00:01:38
Yes. 00:01:41
Thank you, Dr. Kenwright. 00:01:42
Let me just say that I'm here next to Anthony Marino, and we were listening and saying, 00:01:43
These are some good questions, I'll tell you. 00:01:49
Well, Anthony is a student at the Tuckahoe Elementary School, and he actually has a question 00:01:52
that he'd like to ask. 00:01:57
Anthony? 00:01:58
Thank you. 00:01:59
My question is, how did we navigate before GPS? 00:02:01
Oh, all right. 00:02:06
Good question. 00:02:08
And let's see, who'd like to answer that? 00:02:09
All right, Hugh, all right. 00:02:11
That's a really good question, because before GPS, people did navigate. 00:02:15
And so I think the best way to answer that is to take you back several hundred years 00:02:20
ago and show you how some of the early people navigated. 00:02:23
Well, one thing people would do is if they'd go to a certain location, as they traveled 00:02:26
over the land, they would mark where they went, and they'd make a map. 00:02:31
And that would become a map, and they could give to somebody else, and they could navigate 00:02:35
the same route. 00:02:38
In fact, we still use that today. 00:02:39
We have highways, that's a path, and we have road maps, and that's how we get from city 00:02:41
to city. 00:02:46
So you'll see some of these techniques, even though they're very old, they still use them 00:02:47
today. 00:02:49
Another technique was developed when we invented the compass. 00:02:51
Now the compass has a needle that points to the north, and if you know what direction 00:02:55
you're going to go, you point in that direction and you see the angle, and that's called a 00:02:59
bearing. 00:03:02
And you follow that bearing, and then you can travel in that direction. 00:03:03
Again, the compass is still used today. 00:03:06
Any aircraft that you fly in will have a compass. 00:03:09
That's great. 00:03:11
So what I'm hearing from you is some of the tools from the past are still being used today. 00:03:12
That is true. 00:03:16
That's great. 00:03:17
It's a combination of all of these tools, and they help back up each other, and make 00:03:18
sure that you have a more accurate path of direction. 00:03:23
Fantastic. 00:03:26
Great. 00:03:27
That's a good answer. 00:03:28
And I know we've got someone else back there with Mrs. Garvey. 00:03:29
So Mrs. Garvey, could you please introduce for us your guest, and then the question, 00:03:31
please? 00:03:35
Well, yes. 00:03:36
Thank you very much. 00:03:37
We're joined by a wonderful young student named Brittany Jones. 00:03:38
And Brittany is from Bradbury Heights Elementary School, and she has a question for us today. 00:03:42
Thank you. 00:03:48
My question is, how does GPS work? 00:03:49
That's great. 00:03:52
All right. 00:03:53
How does GPS work? 00:03:54
You got something there for us? 00:03:55
Yes. 00:03:56
I expected this question, and I used this illustration to try to answer that question. 00:03:57
The GPS satellite sends signals down to the earth, and then the receiver on the earth 00:04:02
makes measurements on these, and the first thing it does is determine the distance or 00:04:07
range to those satellites. 00:04:12
So let's let this wire here represent the range from this satellite, and this one the 00:04:14
range from this satellite. 00:04:19
Then with mathematical equations in the computer of the GPS receiver, it calculates where these 00:04:22
ranges intersect, and that becomes your latitude and longitude of your position on earth. 00:04:29
All right. 00:04:34
Well, Dan and I were able to get where we needed to go. 00:04:35
All right. 00:04:38
Well, I see we're quickly running out of time. 00:04:39
Thank you, Dick and Hugh. 00:04:40
Oh, but I understand we have a special caller with a message. 00:04:41
It's from Senator and astronaut John Glenn. 00:04:45
Mr. Glenn, welcome. 00:04:47
Thank you. 00:04:48
Glad to be able to participate this morning. 00:04:49
Thank you. 00:04:52
I understand you have some words for our viewers. 00:04:53
I do indeed, and I'm glad to be able to give some encouragement to our young people today. 00:04:54
You know, today is the 95th anniversary of when the first airplane ever lifted off the 00:04:59
ground under powered flight, when the Wright Brothers made that first flight from Kill 00:05:03
Devil Hill down in North Carolina. 00:05:09
And it wasn't a very long flight, but they were the first people to ever get airborne 00:05:12
in a powered vehicle. 00:05:17
And ever since then, we've been trying to go higher and faster and higher and faster, 00:05:18
and we're into space now. 00:05:22
And you might even look at the Wright Brothers as the first astronauts, if you want to look 00:05:24
at it that way. 00:05:28
They didn't get where they were and make their discoveries by just having an interest 00:05:30
in it. 00:05:34
You know, they were people who studied things. 00:05:35
They made little wind tunnels at the time. 00:05:37
They did the mathematical measurements. 00:05:39
They had to know their mathematics, and they had to have a scientific mind. 00:05:41
And that's what we like to encourage in all our young people today. 00:05:46
You just have to have the background that you get from school with regard to math and 00:05:49
reading skills and all those other things. 00:05:53
And that's the good part about being in school. 00:05:57
You all have the ability and the place that you're at now in school to do all those same 00:06:00
things and make tremendous contributions in the future, just like the Wright Brothers 00:06:05
did 95 years ago. 00:06:10
Senator Glenn, thank you. 00:06:12
Powerful words there, and I appreciate it. 00:06:13
Now, if you want to discover more ways researchers are using GPSN, check out our website. 00:06:15
And for those of you interested in the world of transportation, check out the online resources 00:06:19
of our program partners. 00:06:23
We're going to have to say goodbye now. 00:06:25
Let's wrap up. 00:06:26
Thanks, program partners and all our guests. 00:06:27
Thank you. 00:06:29
Here, you will engage in an online road rally that will take you to five continents with 00:06:30
a checkpoint on each continent as seen from space. 00:06:34
