 Blockchains

Ownership on the Bitcoin blockchain is determined by a pair of cryptographic keys. The first, called the public key, resides in the blockchain for anyone to see. The second is called the private key, and its owner keeps it safe from view. The two keys have a special mathematical relationship that makes them useful for signing digital messages. Here’s how that happens: Helmut takes a message, combines it with his private key, does some calculations, and ends up with a long number. Anyone who...

 The Tragedy of Never Understanding Our Children

You must face the fact that yours is the last generation of homo sapiens. As to the nature of that change, we can tell you very little. All we have discovered is that it starts with a single individual—always a child—and then spreads explosively, like the formation of crystals around the first nucleus in a saturated solution. Adults will not be affected, for their minds are already set in an unalterable mould. In a few years it will all be over, and the human race will have divided in tw...

 Science Does Not Rob Life of Purpose

Presumably there is indeed no purpose in the ultimate fate of the cosmos, but do any of us really tie our life's hopes to the ultimate fate of the cosmos anyway? Of course we don't; not if we are sane. Our lives are ruled by all sorts of closer, warmer, human ambitions and perceptions. To accuse science of robbing life of the warmth that makes it worth living is so preposterously mistaken, so diametrically opposite to my own feelings and those of most working scientists, I am almost driven to...

 The Life of a Horticulturist

I have always liked horticulturists, people who make their living from orchards and gardens, whose hands are familiar with the feel of the bark, whose eyes are trained to distinguish the different varieties, who have a form memory. Their brains are not forever dealing with vague abstractions; they are satisfied with the romance which the seasons bring with them, and have the patience and fortitude to gamble their lives and fortunes in an industry which requires infinite patience, which raise ...

 The Message Aboard Pioneer 10 as a "Cosmic Rorschach Test"

The message aboard Pioneer 10 has been good fun. But it has been more than that. It is a kind of cosmic Rorschach test, in which many people see reflected their hopes and fears, their aspirations and defeats – the darkest and the most luminous aspects of the human spirit.

 Man is Noble...

Man may be excused for feeling some pride at having risen, though not through his own exertions, to the very summit of the organic scale; and the fact of his having thus risen, instead of having been aboriginally placed there, may give him hopes for a still higher destiny in the distant future. But we are not here concerned with hopes or fears, only with the truth as far as our reason allows us to discover it. I have given the evidence to the best of my ability; and we must acknowledge, as it...

 Einstein on Being Raise Religious

When I was a fairly precocious young man I became thoroughly impressed with the futility of the hopes and strivings that chase most men restlessly through life. Moreover, I soon discovered the cruelty of that chase, which in those years was much more carefully covered up by hypocrisy and glittering words than is the case today. By the mere existence of his stomach everyone was condemned to participate in that chase. The stomach might well be satisfied by such participation, but not man insofa...

We are programmed by our parent's religion, and are freed from the burden of a personal god through rationalism and exploring nature.

 We Must Apply the Scientific Method to Ourselves

If it is to be applied consistently, science imposes, in exchange for its manifold gifts, a certain onerous burden: we are enjoined, no matter how uncomfortable it might be, to consider ourselves and our cultural institutions scientifically and not to accept uncritically whatever we're told; to surmount as best we can our hopes, conceits and unexamined beliefs; to view ourselves as we really are. Can we conscientiously and courageously follow planetary motion or bacterial genetics wherever th...

 The Circle of the Brain cannot be Squared

A Circle round divided in four partsHath been great Study 'mongst the men of Arts;Since Archimed's or Euclid's time, each BrainHath on a Line been stretched, yet all in Vain;And every Thought hath been a Figure set,Doubts Cyphers were, Hopes as Triangles met;There was Division and Subtraction made,And Lines drawn out, and Points exactly laid,But none hath yet by Demonstration foundThe way, by which to Square a Circle round:For while the Brain is round, no Square will be,While Thoughts divi...

 Notes from the Science-Art Session

No direct quote for this meme.

Summaries of comments made during the science art session by artists and audience members:

  • Hawks – interested in reconstruction, detailed realism, Neanderthal terminator, there is a tradition in anthropology of illustrating, Neanderthal are reconstructed to look doomed and confused, like it when illustrators and artists bring humanity into them, humor, Kenise Brothers give smiles to them, pose them, which isn’t scientific because we don’t know these things, but also more scientific because it isn’t so clinical
  • Orr – orogenic.blogspot.com geometric, abstract illustrations of birds
  • Links ot other artists on the wiki page: Carl Buell, etc http://scio11.wikispaces.com/Science-Art
  • Radiohead/Nine Inch Nails Model: put a lot free stuff online in hopes of eventually being hired to do something custom, people expect images for free
  • Criticism of Mellow's Darwin painting: the steps were too linear, it should have been a bush growing out of his head
  • Svpow.wordpress.com – fantasy images of brachiosaurs, not scientifically accurate, but memorable. Brian Ang.
  • My Favorite Anthropology Sculpture of Homo Erectus at the Hall of Human Origins - post a link to this image in the wiki.
  • The monkey rising to become man iconic image is really wrong and hurts evolution’s image outside of the field. Mitochondria is another example, in cells they are not blobs, but are networked.
