Quote for the day,

"There is no god like the throat: it takes sacrifices daily." ~Nigerian Proverb


The Pluto mission will indeed be exciting; but, even before New Horizons spacecraft gets to Pluto, the Dawn spacecraft, having already revealed the Vesta asteroid as wonderous, will have explored Ceres and will be exploring Ceres.  Ceres is the biggest asteroid of the asteroid belt in between Jupiter and Mars.  Vesta is the second largest.  And, this October, a comet will streak right past Mars!  This next year is exciting indeed! 

The LHC collider will also be up and running again at higher energies to search of dark matter and hidden dimensions.

A working space drive? Space exploration enthusiasts have longed for a space drive for a long time. This one has people excited; it's passed a third party test. What it is microwaves generated from the solar sails; the microwaves are put in a cavity where they interact with the vacuum energy.  Vacuum energy is probably the greatest finding of quantum physics.  It's a Paul Dirac generalization of Heisenberg's uncertainty relations.  Getting to the point, with little explanation of Heisenberg's uncertainty principle, if particles disappear within the limits of the uncertainty principle, then particles can pop into existence out of nowhere.

Science/technology extra,


and I can't help perhaps reposting this news,


Both of these explorations gives new evidence for dark matter.

"I do not know what I appear to the world; but to myself, i seem to have been only like a boy playing on the seashore ,and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me." - Isaac Newton

"The time will come when diligent research over long periods will bring to light things which now lie hidden. A single lifetime, even though entirely devoted to the sky, would not be enough for the investigation of so vast a subject . . . And so this knowledge will be unfolded only through long successive ages. There will come a time when our descendents will be amazed that we did not know things that are so plain to them . . . many discoveries are reserved for ages still to come, when memory of us will have been effaced. Our universe is a sorry little affair unless it has in it something for every age to investigate . . . Nature does not reveal her mysteries once and for all." - Seneca, Natural Questions, Book 7, first century A.D.

Mathematics is not a book confined within a cover and bound between brazen clasps, whose contents it needs only patients to ransack; it is not a mine, whose treasures may take long to reduce into possession, but which fill on a limited number of reeins(not to sure about this word in my quote) and lodes; it is not a soil, whose fertility can be exhausted by the yield of successive harvests; it is not a continent or an ocean, whose area can be mapped out and its contour defined; it is as limitless as that space which it finds too narrow for its aspirations; its possibilities are as infinit as the worlds which are forever crowding in and multiplying upon the astronomical gaze; it is as incapable of being restricted within assigned boundaries or being reduced to definitions of permanent validity, as the consciousness of life," - James Sylvester

I like this one when you size it up; you can see lots of galaxies, even galactic clusters in the background.  It's too bad the galaxy on the far left side is halved!

- I wasn't able to size it up enough just by clicking on the image provided here on this blog; but, by making it your desktop image, the image is the right size!

Science/tech news extra,

Meet the electric life forms that live on pure energy



Flight design keeps advancing.  One could imagine solar powered propellers as well.  And then, imagine 3d printing one of these?

Well, I'm finding all kinds of exciting futuristic aerospace videos! New 3-Story "Sky Whale" Design for Future Airplanes

Strange & Extreme Airplanes (Aeroplanes) I thought I'd show some of the past creativity as well.

An weird idea of mine that isn't about airplanes, but because of the nuclear powered bomber mentioned in the 'strange and extreme airplanes' link above, I thought I'd mention this. A year or two ago, I thought of making a hugh tank.  A tank the size of a luxery boat, or the largest private boats you see.  How to move it?  Make it nuclear powered just like nuclear powered submarines.  I'm actually surprised no militaries in the world have ever thought of this!

"I will not go so far as to say that to construct a history of thought without profound study of the mathematical ideas of successive epochs is like omitting hamlet from the play which is named after him. That would be claiming too much. But it is certainly analogous to cutting out the part of Ophelia. This simile is singularly exact. For Ophelia is quite essential to the play, she is very charming, and a little mad. Let us grant that the pursuit of mathematics is a devine madness of the human spirit, a refuge from the goading urgency of contingent happenings." - A.N. Whitehead

"Mathematics, rightly viewed, possesses not only truth, but supreme beauty - a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show," - Bertrand Russel

"We have found that where science has progressed the farthest, the mind has but regained from nature that which the mind has put into nature. We have found a strange footprint on the shores of the unknown. We have devised profound theories, one after another, to account for its origin. At last we have succeeded in reconstructing the creature that made the footprint. and Lo! it is our own!" - Sir Arthur Eddington

"the question of the foundations and the ultimate meaning of mathematics remains open; we do not know in what direction it will find its final solution or even whether a final objective answer can be expected at all. "Mathematizing" may well be a creative activity of man, like language or music, of primary originality, whose historical decisions defy complete objective rationalization." - Herman Weyl

Quote for the day,

"It can be of no practical use to know that pi(the ratio between the diagonal and circumference of a circle) is irrational, but if we can know, it surely would be intolerable not to know." - E.C. Titchmarsh

Mathematical scientists only need to know pi from 16 to 32 decimal places - at least, so far. Computer engineers like to test their latest computers by determining pi(and other mathematical things like factoring digits, e, and others) to ever greater decimal points.  The current record holder is around 11 trillion decimal points! Well, I guess scientists have a long ways to go before they can require as many decimal points as are now available to them!

Quote for the day,

"Whatever may be one's opinion as to the simplicity of either the laws or the material structures of Nature, there can be no question that the possessors of such conviction have a real advantage in the race for physical discovery. Doubtless, there are many simple connections still to be discovered, and he who has a strong conviction of the existence of these simple connections is much more likely to find them than he who is not at all sure that they are there." - Percy Bridgeman

Nanotech news extra,

Direct Laser Writing of 3D Architectures of Aligned Carbon Nanotubes . I recall an arxiv article about making a nanomachine that can pick and place single atoms.  This was so many years ago; I wasn't even trying to keep track of new developments back then.  Still, assuming that arxiv article was correct and this laser writing of nanotubes works, we should be able to 3d print nanomanufacturing systems right now. I tried to contact one of the engineers of this article, but I haven't gotten any reply!  Oh well . . .
