For himself by make -- math and science fun for kids now even twenty years later.
Bill Nye the Science Guy has no plans of slowing down why woody that's right here to celebrate his twentieth anniversary -- -- show us a few things about -- in other planets is.
Bill Nye the science and space guy good morning bill well sets there's this interaction good luck -- -- All right so you're talking about science today we obviously have a prop.
Tests -- -- so oh so this is the kickoff.
The Toshiba -- for -- vision.
National -- -- association and the planetary society's big effort to get.
Young people involved in -- -- vision competition and I now have a day job cuts which I can tell you cuts into your time I think I.
I -- this scenario of of the Planetary Society this organization started by a guy you may remember Carl Sagan chair so now we've Nixon's uncle bill's here now we -- -- -- section.
Excellent and so one of the questions is how to these people find planets.
Orbiting distant distant stars but when you can't see the planet.
So you build one of these we'll give you instructions in the magazine.
And what you detect it's not the planet itself.
But that slight wobble.
What's that star.
Well when you see it start wobbling with your extraordinary telescope -- the only reason it could be wobbling is because the center of mass of the planet's -- system.
-- making the thing shake.
Like a hula dance suite is an -- -- -- shaking because of the elastic band had great well you're seeing it actually.
That's a practical reason but it actually it -- -- wobbles a bit in in nature video but -- they did it yes so our son.
Wobbles a little bit on account of the gravity of the planets in orbit around.
Interest and so we're -- distant suns have the same feature so when I was young.
Lot of speculation are there planets around every star interest.
Who knows all of them there might be and you remember the Drake equation -- -- religion so there's only maybe discipline around every won't mean.
100000 -- now there's planets around every start there are almost every star apparently.
And we detectable by looking so there's a whole bunch of motions.
What would that be.
-- -- -- Beckham forcing us to watch it's useless so what she sees what's the real thing you can look for where the telescope.
Right narrowed -- current level of technology is that white ball slightly moving back and.
For marriage to now I know you're you're told you've been instrumental in getting kids in keeping kids interest it.
In in science and I and I have little kids at home and they're so no interest in coming home in talking about the stars and the moon what they learned in school but.
Spending a lot of those kids -- this when those designs technology all these other countries and I -- NN.
Well if you're asking me and I got the impression you were -- and a we hit somebody needs to invest in this and the other big thing we need does this sound strange a big thing we need to invest in this algebra.
And algebra or apparently is this turning point.
If you don't embrace algebra and then you have trouble apparently or -- reluctant to.
Think abstract -- -- a whole bunch of things.
So -- -- -- 31 years old with the help of Toshiba and the national science teachers association.
It is co sponsoring explorer vision.
This competition that gets kids excited about math and science check -- -- -- -- -- dot com check out Toshiba.
Submit your question or not some -- vote for your question we will answer on video and today I will be in Times Square.
With the cooking videos the first two aspects are nothing but fun it's great to see everybody -- I my sense is it's time to wrap it is we -- got us dare I say it's much we manage spin it maybe the world.
Very nice -- night assign an old guys are great to see you on good morning thanks for -- in the interest of -- -- may have.
