DIY bionics - making kids smile again.
See the joy in Liam’s eyes as he is grasping a ball with his right hand for the first time. By the time this cute fellow grows up, he will have a bionic hand that will be connected to his neural-system and be indistinguishable from his biological body; but for now all Liam cares about is being able to play ball.

This is my guy. Thanks for the inspiration Dr. Feynman.(via jtotheizzoe)
Please disproof or tell me this is an irrelevant statement.
Does the big-bang theorie not state that everything is in motion all the time until the big crunch or freeze?
I’m stuck and probably as ignorant as a fly.
Now that’s something to celebrate! And the best part is that I can set my sources.lst to point to the new testing release Jessie and get things messed up again. Now doing a apt-get update and apt-get upgrade. Weee weee wheezy…
A Boy And His Atom: The World’s Smallest Movie
Scientists are known for loving their work. Biologists tend to their cultures and animals. Physicists polish their exquisite machines like sports car entusiasts treat vintage Ferraris. So do chemists love atoms? Apparently they do. At least enough to write a love story with, and about them.
IBM scientists have created the world’s smallest movie using individual atoms. It’s the story of a boy and his playful atom buddy, drawn in stop motion and with each quantum pixel positioned using a scanning tunneling microscope. Every frame is magnified a stunning 100 million times!
This amazing feat was accomplished by using a charged atomic needle to drag single carbon monoxide molecules (the individual atoms we see are one side of that two-atom molecule) around on a copper substrate. I’ve posted a little bit about these feats of atomic art before, with these “quantum corrals” and “ferrous wheels”.
See those ripples around each atom? They remind me of pebbles being tossed into a still pond. They are actually ripples in the electron field of the copper surface below! It’s a reminder that, contrary to many textbooks, electrons behave more like waves than particles following an orbit. And like any other wave, they can form intricate interference patterns. Check out this previous post for more on that.
The hope is that manipulating atomic structures like this may lead to even greater information storage capacity. Imaging all the world’s books and movies on your mobile phone at once!
Here’s a “making of” movie from IBM, featuring the sound of atoms being moved as well as the encouraging sight of several female team members.
This makes me as happy as atom boy there.
Carl Sagan on humans (from The Sagan Series) [x]
The key word there is “we”. We define what it means to be human… together. But at the same time what’s “meaningful” in life is up to you, the individual.
That’s both awesome and horribly confusing at the same time.

1. All beliefs in whatever realm are theories at some level. (Stephen Schneider)
2. Do not condemn the judgment of another because it differs from your own. You may both be wrong. (Dandemis)
3. Read not to contradict and confute; nor to believe and take for granted; nor to find talk and discourse; but to weigh and consider. (Francis Bacon)
4. Never fall in love with your hypothesis. (Peter Medawar)
5. It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories instead of theories to suit facts. (Arthur Conan Doyle)
6. A theory should not attempt to explain all the facts, because some of the facts are wrong. (Francis Crick)
7. The thing that doesn’t fit is the thing that is most interesting. (Richard Feynman)
8. To kill an error is as good a service as, and sometimes even better than, the establishing of a new truth or fact. (Charles Darwin)
9. It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so. (Mark Twain)
10. Ignorance is preferable to error; and he is less remote from the truth who believes nothing, than he who believes what is wrong. (Thomas Jefferson)
11. All truth passes through three stages. First, it is ridiculed, second, it is violently opposed, and third, it is accepted as self-evident. (Arthur Schopenhauer)
