Wasn't easy being a planet hunter back in the day *promote

I'm looking for
1 tug
The pull of a planet
1 tell
A wobbling sun
I've searched for years
Haven't found a one
But they're out there

1 jump
In radial redshift
1 slip
Of spectral lines
They'll see if I can show them the sines

Pish tosh
Green men
Take five
Take ten

Just a little cash guys

Budget's tight
Don't fund this trash guys

I can take a hint
Better face the facts
Second-hand'll have to do

Eww
All you planet hunters at the bottom
You've got fact & fantasy entwined
Finding planets except they haven't got one

Well they gotta be forming readily
When you think about it given we've got nine

1 jump
A blip in the spectrum
1 shift of meters per second
1 graph of period power
They laugh but I'm not sour

Here goes
18 months of data
Cross & correlate it
All I gotta do is run

Pish tosh
Green men
Ah don't mind them
If only they'd look closer
Would they see a pure void
No sirree
They'd find out
There's worlds galore
To see

Make way for Pegasi
51 Pegasi

First was a world
Round an old pulsar
That's true
But the news
Is a sun-like star
With wobble
Too quick & precise
To be designed
No fluke not a spot
If you like it hot
You're gonna love this find

Pegasi 51b
Planet discovered
Orbit traced
Every 4 days
Hot as can be
Its order-Jupiter size
Was something of a surprise
Especially given its star's proximity

Pegasi 51b
It's a new era
To detect
Exoplanets
Soon there'll be three
As planet pulls on its Sun
It shifts the stellar spectrum
That's how we found 51b Pegasi

How'd a planet get so close in orbit
Cause I thought you needed ice to form it
Did it later undergo some strange migration
Star too small to be so long-pulsating
And too old to be so quick rotating
Is there any other good interpretation

This will certainly help with our funding

We got your funding
We got your funding

Got a surface of 1200 C

It's treacherous
So treacherous

If in time this new breakthrough feels mundane
Planets are common

That's proof
Of the truth
I've been telling you
This is no mean anomaly

Pegasi 51b
Planet uncovered
Round a far
Main sequence star
Spectral type G
We know its mass to be high
Half Jupiter by sine i

It's 15.61 pc from home
And it shakes our faith in how planets are formed
And its star is in Pegasus
Give it an A and thus
Label the planet as b
51 Pegasi

Plotting Doppler shifts is glacial-pace
And that astrometry never prevails
But baby you're in luck cause
Up in space
You got a planet-finder never fails

You got the power of statistics now
You got a view without an atmosphere
So no more nights spent locked up in your tower
All you gotta do is wait right here
And I say

Kepler the planet-searcher
Got a dip, no 2, no 3
We just measure brightness
Plot it out & that's transiting photometry

When your stars do this
And your curves displace
Then your star's got this
Transiting its face

Then you hit compute
And lookie here

You get good diameter data
From that dip
And orbit distance from the length of year

Well now we need this tale supported by
A ground observer with a good Échelle
We got 2000 planets certified
2000 more that only time will tell

But let's take em all, plot em out
And find out if we're really all alone
Is there a rocky world we've found no doubt
That orbits in the habitable zone
Like home?

Kepler the planet searcher
Got an Earth 452b
Part of a throng
40 billion strong

There ain't never been a field
Clever as the field
There ain't never been a field
Better than the field they call
Exoplanetology

I can show you a world
A shining shimmering planet
Found concealed in the band-shifts
Of the closest star in sight

I've found hope in the skies
And facing wonder I wonder
Could the sine wave discovered be
A planet fit for life

A whole new world
A new fantastic point of blue
Placed in that narrow zone
Where water flows
Midway tween cold & steaming

A whole new world
Its sun a faint, reddish hue
Could there be waiting here
A biosphere
Evolving in this whole new world to view

Fathoming a whole new world to view

Unbelievable find
Indescribable feeling
Earthlings someday revealing
Through directly captured light
A whole new world

Don't just stare from a far

Though nigh impossible to see

Wouldn't close up be bolder

Next to its parent's flair
If life is there
We'll know through atmosphere spectroscopy

A whole new world

Block the glare of the star

A laser starshot to pursue

With a star-shaped occulter

Chasing that crazy dream
That's always been
Of walking in a whole new world with you

a whole new world
That's where we'll be
A thrilling chase
A home in space
For you and me

that video is very cool>> ^Jinx:

>> ^surfingyt:
im kinda let down the helicopter wasnt turned on fully

I remember seeing a video on the sift where somebody does that (only looking out, not in). You get a really wierd effect because of the way the camera samples. Turned the landscape into a sort of sine wave. http://youtu.be/EnrwrwMfNSs
Assuming you could mount the camera to the blade tip so it wouldn't fly off, balance the blades and then spin them up to a multiple of the cameras refresh rate I'd wager you'd get a similar effect. You might be able to see the front and back of the Helicopter simultaneously

>> ^Payback:

The camera is on it's side. The scan lines are perpendicular to the rotational axis. By the time the camera takes one sweep of video, it's physically spun a few times, so what you're getting is a strobe effect which grabs info from all over the place.


This is what is causing the really wide angle view. It looks like the camera is catching nearly a 360 degree view of the horizon (you can see from the thumbnail pic that there's an almost complete sine wave in the horizon).

Who the hell thought this would be a good idea in the first place? And I'd love to see a video of their face when they first played this back and it wasn't just a load of blury bollox

Very interesting. The sine waves are because you are seeing a very wide angle image and the axis of the blades isn't perfectly perpendicular to the horizon. The wave is controlled by the angle of the axis of the rota, not the speed. Altering the speed a little would move the position of the peaks of the wave across the image, but not alter the height of the waves.

At the points in the video where the axis of the rota is pependicular to the horizon the horizon appears as flat. This is because as the rota spins the horizon appears in the same place in the image throughout the rotation. As the helicopter learns the camera will at some points be looking below the horizon, and at others it will be looking above the horizon, hence the sine wave effect we see. The high points in the wave are when the rota is looking low, the low points when the rota is pointing high.

If the axis of rotation of the rota is parallel to the horizon you get the vertical lines of ground/sky/ground/sky, since this is what the end of the blade is pointing at as it rotates

Awesome experiment. This would be a boring blur of a video except that the 60 frames a second taken by the camera matches the 60 cycles per second of the rotating blade. The sine wave distortions are the result of minute changes in the speed of the blade as it moves around.

I have seen distortion shapes like this experimenting with waves on oscilloscopes in a lab, but have never seen them mirrored in real life before.

@rottenseed: Well, as a physicist, I definitely encounter the factor 2 pi much more often than pi. I conjecture that this is true in mathematics as a whole as well, since 2 pi = tau is one full turn of a circle, and one full period of a (co)sine wave. Tau is as such a more convenient choice, if you have the luxury to choose.


Meet me at my lair, we will discuss in detail on how this girl and whomever wrote that shite manifesto are shortsighted and why...

Will include orgasmic information that will melt these mortal's minds. We'll make it private so no buddy stumbles in by accident a turns to stone.

"Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. "

as per ol'wikipedia, Yes that is the one I meant, I always thought they meant the same thing. Thats what my mind envisions when I visualize the humming or the blades, the sound goes up and down within a certain bandwidth and thats what I listen to, without it I just sit there and think or sing in my head, I need something to concentrate on and I have used a fan for that purpose since I was in grade school.


its just one continuous Sine wave visualized and poof I am asleep.

I agree with you in basic principle, but I don't think the job-loss to job-replacement is at a one-to-one ratio when true automation and computer technology comes into play. In my mind there's a U-shaped regional employment curve relative to technological growth, with technological progress over time as the independent axis and employment level the dependent. Employment starts at one level along with a given level of technology, some big progress takes place that causes employment to drop, and then over time the region will adjust its educational and business practices in order to bring the employment curve back up to near former levels. And then the process would repeat itself. Sort of a sine wave... but every period the amplitude is reduced unless external factors (mainly political) mitigate the drop-off ratio.

So in the USA manufacturing jobs are going bye-bye, as are many IT jobs, as a consequence of economic and technological change, along with the shrinking disparity in education levels between the USA and mainly BRIC countries. Most of the newly unemployed will find replacement jobs, or be trained to work in off-shoot industries or newly arised industries. But again not all of them will find re-employment before the next drop off, unless the politicians are really doing their jobs.

The first track Polygon Window appears on the Surfing on Sine Waves album by the Aphex Twin.

Thats no loopty loop, thats just flying in a sine wave like shape. I've been in small planes doing this, and have spun my 35mm camera around in front of me, it "floating freely" in space.

In reality of course, even when the dog is sticking to the ceiling, he is falling towards Earth as fast as if you'd kicked him out the door of the airplane. The airplane is just falling faster.
