Calculus is summing lots of tiny inputs and making an output. Neurons sum a lot of tiny inputs and make an output.

Because your eyes are left and right of each other. Tilt your head 90 and try again.

I also use keypass+dropbox+iphone+Minikeepass.
Why is a keyfile an excellent option? If you only have 500,000 files on your computer (I bet you have less on your iphone), it can't take long to try them all - that is less secure than a 6 digit PIN, isn't it?
Or do you mean keyfile+passphrase? But isn't the effort to find the path of the keyfile more clicking/typing than an extra 6 digits??

That's what we said in the early 1990's when people were talking into mobile phones. Times change.

You are talking like a horse lover from the end of the 19th century who looked at cars and said "it'll never work - you cannot feed it".

Here is a beautiful interactive 3D simulation of how Rosetta got to where it is now. Where is Rosetta?. Video
The choreography of the Earth, Mars, Earth, Earth slingshots is just amazing.
Here is the complex orbits to come of Rosetta around the comet Orbit around Comet

Is there a genuinely secure mechanism for an app to store a password internally? I imagine they mostly just store an encrypted version of the password using a standard algorithm with an fixed "unknown" key/salt in the code. Isn't this just an example of security through obscurity?

This speed is still very fast if it is taken relative to us or to the galactic center. The galaxy's speed relative to the cluster plays no role at these sizes and time scales. "sitting idle-ish and the galaxy zipping past" is the classic Relativity - it makes no difference - both are identical. In either case something caused that Star's velocity relative to us to by very different.

You sound like the people in my grandmother's village in 1905 when the first car drove in - "It won't last - you can't feed it like you can a horse".

go and look at Ozone depletion and see that the alarmism was worth it because the world did ban CFCs and the charts show the improvement since. What we need is global coordinated action on the issues of today
Icebreakers being stuck in ice doesn't say much about climate change - incidents of such icebreakers stuck in ice over many decades may say something. Don't confuse an incident with a trend
I am sure there are many stupid Americans in New England seeing how amazingly cold it is this week and mocking Climate Change. (I live in Central Europe and we have at the moment one of the hottest Januaries on record). Climate Change predicts weather extremes because there is more energy available in weather systems to push to hotter and colder extremes.
That thick ice in Antarctica could be an example of climate change if, for example, more ice is rolling off the land faster, or climate change has changed currents to push more ice into that bay. Only objective longterm observations can help here.
There are problems with Alarmism, but it was right with Acid Rain in the 1970s, leaded petrol and Ozone in the 80's - those problems were reversed - and the scientific community is in consensus that CO2 today is a far more serious issue and we need alarmism before we reach tipping points.
I would rather take action with alarmism, then do nothing out of cynicism while species go extinct and Africans and Bangladeshis try to emigrate in their millions.

Ken Ham has been playing this game since at least the early 80's. He is not an idiot - he is just convinced that Genesis 1 is literally true and that all Genesis-deniers are deceived by the Devil and keeping people from following the one true Creator Jeezuz. This will not be a debate at all - they will both be ignoring each other's positions, digging into the sand and grandstanding - and Ham's organisation gets 25$ per attendee and millions of Youtube views and other media attention.
If Nye does well, then Ham's people will say that Satan is clever or that man's wisdom will be shown foolish at the Last Judgement and warn his followers to not follow the Serpent's smooth words, and that listening to these humanists will imperil your soul.
Ken Ham is an Evangelist with the mission of winning souls by "upholding the authority of the Bible from the very first verse". That is for him the only goal of this "Debate".

Ken Han doesn't have a science agenda, he has an evangelism agenda to win souls for Jesus - and that is all.

You can say what you like about his past, but you don't know what credibility he has been building in 2013. Tanja did not give anyone anything - it was just a stunt to show the absurdedness of the election process. I think we can say "Whoosh" to you.
Here is Athene's credibility for the 10M$. www.savethechildren.org
Now go to his AtheneWins channel and watch his interviews on Bloomberg TV Fox CNN CNBC Wall Street Journal
It would be great if Steam and others took over the idea and donated many millions to charity as a default. Props to Athene for tirelessly kickstarting something great.

This is a EUROPEAN satellite, and so a EURO is very appropriate.
Yes, the Europeans are going back to fundamental mapping of what is out there, like James Cook, Galileo, Johannes Kepler.

Onwards to L2 Gaia!!!

There is no significant difference between 80,000 km and 384400 km. It is only 6.9% more energy than getting from the Earth's surface to 80,000 km. - so getting as far as the Moon is trivial for SpaceX - getting into orbit and landing is another issue though.
SpaceX was launching to low earth orbit and got their in a few minutes - last month they got to geosynchronous orbit in just a few more minutes. The Chinese took 12 days to get to the Moon because they weren't in a hurry and wanted to save energy - Apollo needed to get humans there and back faster.
Elon Musk wants to emigrate to Mars. You can be sure that that he will be playing on the Moon before sending stuff and people to Mars.
