Rally car takes detour through carpark and still wins stage
Perfect example of why spectators lining the course always seem suicidal to me. In off road racing, we tried to think of them as bushes with clothes on, otherwise it's impossible to bring yourself to drive flat out when a tiny mistake might put you 50' off the course. At the least, they shouldn't allow people to sit on the outside of corners and curves.
Whole New Worlds: An Aladdin History of Exoplanets
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
Donald Trump will never be President of the United States
Obama has 8 years to become a president and still failed Americans.
Trump has been in office 3 weeks-- sure he is on a learning curve but even with his mistakes he is off to a great start.
Good one there! "I know you are but what am I?!"
Trump is not afraid to lead? What's he leading in exactly?
An idiotic, poorly thought out travel ban that won't help anything?
Mouthing off to our allies, making us look like idiots? (Mexico will pay for the wall... wait, maybe not, but they'll pay 20% tariffs.... well actually the Americans will be the ones paying... sounds like a solid plan everyone!)
Appointing unqualified cabinet members? Rick Perry for energy secretary.... the department he wanted to destroy... the department that he had no idea manages our nuclear stockpiles... the department whose previous leader under Obama was a nuclear physicist. It's now Rick fucking Perry.
The only thing he's leading in is in being the most embarrassing statesman this country has ever seen, arguing with celebrities on Twitter like a child. This moron was actually ranting about Schwarzenegger and The Apprentice ratings in his National Prayer Breakfast speech. All he had to do was just recite a short passage from the bible or something. But nope, not him. He needs to ask like a 12 year old.
We have a 70-year-old man, who also happens to be THE PRESIDENT, who can't control himself and act the part. He really has a few screws loose. There's no other explanation. But we did give him the nuclear codes! Yaay!
Leader - my ass. (Besides, it's Bannon leading him anyway.)
SSL Now Enforced Site-Wide (Sift Talk Post)
At that moment, Firefox 51.0. But I've had some ciphers disabled since the early days of Logjam attacks, which included all ciphers using Diffie-Hellman without elliptic curves. That's why there was no overlap between accepted ciphers on my end and ciphers supplied by VS.
Which web browser(s) do you use for that?
The Brachistochrone Problem
The curve shown at 7:45 isn't what they built though. Why did they change it?
NÜRBURGRING Rallye Nordschleife wrong way round
Ha! When it started, I was like 'hey, that's not Nuremburg!'
I like the wrong way idea, that way they can't follow the rubber on the road to find the right line around the curves.
Meanwhile in Kazan Airport, Russia
Of course if we keep expanding airports the way we have been we will probably have to build highways in them eventually anyhow. So really, this guy is just ahead of the curve.

Introverts vs Extroverts
I'm on the pretty extreme end of the introversion side of the curve.
I remember talking about introversion vs. extroversion in Psych 101 at college. I think that talking about it in that classroom environment helped to foster a lot of understanding between both sides. Very extroverted people talked about how they would get anxiety on up to physical symptoms of discomfort if they went for several hours with zero human interaction, which completely blew my mind.
But, I'll feel similar discomfort if you drop me into a loud, crowded party. If I'm ever trapped in a situation like that, I quickly escalate from nervous to annoyed to "honey badger in a corner" enraged.
I think there is definitely a societal extroversion bias, but a lot of it is well-intentioned. Many leaders tend to be extroverts, and they sort of "feel sorry" for people who seem to distance themselves from the group. Then they will try to incorporate those people into the group, thinking that they are doing them a favor. But in many cases, that is the exact opposite of what we introverts actually want.
I think that both personality types have advantages that can make them uniquely suited towards specific tasks. A really good leader understands both types and knows how to get the best out of either.

Take your banana-proof of intelligent design and shove it.... well, where 'God' apparently 'designed' it to go (after all, it is curved for easier self-penetration).
Colored Noise, and How It Can Help You Focus
this was oddly uninformative and misinformative. the names for white and pink noise are related to light but brown noise is named after robert brown.
white noise is equal power (amplitude/"volume") across frequencies (1/1), pink noise equal power per octave (1/frequency), and brown/red noise is -6dB/octave (1/frequency^2). there is also grey noise, blue noise, black noise, violet noise, and others. and no mention of the fletcher-munson curve (how sensitive our ears are across the frequency spectrum).

Is Science Reliable?
Theoretically, science works great. However, as has already been noted, in the real world in certain fields, the pressure to publish something "substantial" combined with the inability to get grants for certain experiments because they aren't "trendy" right now causes scientists to self-limit the kinds of research they undertake, which is not at all great for increasing human knowledge.
Another problem is the "expert opinion" problem--when someone with little reputation in the field finds something that directly contradicts the "experts" in the field, they often face ridicule. The most famous recent case of this was 2011 Nobel Prize winner Dan Shechtman, who discovered a new type of crystal structure that was theoretically impossible in 1982 and was roundly criticized and ridiculed for it until a separate group of researchers many years later actually replicated his experiment and realized he had been right all along. This web page lists several more examples of scientists whose breakthrough research was ignored because it didn't match the "expert consensus" of the period.
Finally, in the humanities at least, one of the biggest problems in research that uses a quantitative approach (i.e. statistics) is that researchers apply a statistical method to their data, such a as a t-test, without actually demonstrating that whatever being studied follows a normal distribution (i.e bell curve). Many statistical tests are only accurate if what is being studied is normally distributed, yet I've seen a fair share of papers published in respected journals that apply these tests to objects of study that are quite unlikely to be normally distributed, which makes their claims of being "statistically significant" quite suspect.
There are other statistical methods (non-parametric) that you can use on data that is not normally distributed but generally speaking a test of significance on data taken from a normally distributed pool is going to be more reliable. As is noted in this video, the reason these kinds of mistakes slip through into the peer-reviewed journals is that sometimes the reviewers are not nearly as well-trained in statistical analysis as they are in other methodologies.
