Stories | Science Fiction | +Ian Miller

Book on heavy discount!

Sci fi with economics! (And unique frauds).

That's what the blurb indicates; I have yet to read the actual book. But Ian Miller focuses on solid science (and economics), so you're safe.

#StoriesOnGooglePlus #ScienceFiction #IanMiller
From April 13 – 19, Red Gold is on Kindle Countdown discount, for those in the US and UK. (Don't blame me for other Amazons.) The colonization of Mars leads to the opportunities for a massive fraud on Earth, which David Gill, on Mars must stop. Pity his business partner is generating the fraud, and has the only guns on Mars. The background also shows the difficulties settlement on Mars must overcome, but it also shows some ways to overcome them. An example: it proposes a superconducting magnet at the sol –Mars L1 position years before NASA did. http://www.amazon.com/dp/B009U0458Y

Stories | Science Fiction | Free Book | C. Gockel

Since I haven't read it yet, I'm quoting from the Amazon page:

In the year 2432, humans think they are alone in the universe. They’re wrong.

Commander Noa Sato plans a peaceful leave on her home planet Luddeccea ... but winds up interrogated and imprisoned for her involvement in the Archangel Project. A project she knows nothing about.

Professor James Sinclair wakes in the snow, not remembering the past twenty four hours, or knowing why he is being pursued. The only thing he knows is that he has to find Commander Sato, a woman he’s never met.

A military officer from the colonies and a civilian from Old Earth, they couldn’t have less in common. But they have to work together to save the lives of millions—and their own. Every step of the way they are haunted by the final words of a secret transmission:

The archangel is down.

Stories | Science Fiction | Free book | Jay Allan

Since I haven't read it yet, I'm quoting from the Amazon page:

Erik Cain joined the Marines to get off death row. The deal was simple; enlist to fight in space and he would be pardoned for all his crimes.

In the 23rd Century, assault troops go to war wearing AI-assisted, nuclear-powered armor, but it is still warriors and blood that win battles. From one brutal campaign to the next, Erik and his comrades fight an increasingly desperate war over the resource rich colony worlds that have become vital to the economies of Earth's exhausted and despotic Superpowers.

As Erik rises through the ranks he becomes a deadly warrior, and he finally finds a home, first with the Marines who fight at his side and later among the colonists - men and women who have dared to leave everything behind to build a new society on the frontier, one where the freedoms and rights lost long ago on Earth are preserved.

But causes can be fleeting, imperfect things. Amidst the blood and death and sacrifice, Erik begins to wonder. Is he fighting the right war? And who is the real enemy?

The First Book of Jay Allan's Bestselling Crimson Worlds Series (over 800,000 books sold)...

Stories | Young adult Science fiction | +Douglas Foland

So, this is how the book starts:

The adventure begins when 14-year-old Sara Baker witnesses a UFO crash-landing. theneutrinosaga.com - NEUTRINO, The Story Begins

Sara’s reflexes snapped to life only an instant before the aircraft reached the stream. She took two running steps to her right and dove just as it jumped the far bank. The front of it dropped into the knee-deep water, throwing a wave of white spray high in the air. For an instant, frozen in midair, Sara was framed by the white splash of water, the aircraft nearly obscured in the spray. Then time sprang forward and Sara landed hard on her stomach in the grass as a torrent of cool creek water cascaded over her. The aircraft slammed into the near stream bank, splattering a blast of brown mud and silt into the air. Its momentum rocked it forward, nearly flipping it over. Its tapered tail fell slowly onto the far bank where it landed with a thud.

Seems interesting, no?

Space | IRNSS - 1I to launch on Yuri Night

Just a quick post to mention thst when IRNSS-1I launches tomorrow, it will also be 57 years to the day from when the first human went to space. 12 April is celebrated worldwide as Yuri Night in honour of Yuri Gagarin, Earth's first human cosmonaut.


* अंतरिक्ष | IRNSS-1I यूरी रात्रि को प्रक्षेपित होगा*
कल जब IRNSS-1I प्रक्षेपित होगा, तो यूरी गागारिन के पहले अंतरिक्ष यात्री बनने के पूरे ५७ साल होंगे. १२ अप्रैल विश्वभर में यूरी रात्रि के नाम से मनाई जाती है.

Space | Venus

When I was a kid, Venus was supposed to be the place with all the life. Mars? Probably barren.

However, with the probes that actually landed on Mars, and then the gorgeous photos of distant Saturn by Cassini, the heart-shaped planitia of Pluto and the difficult life of Juno as I type, the focus is all outward bound.

So it was neat coming across this article as to how life on Venus may be somewhat more likely than on Mars, and also about how research may actually be done on (or above, if you insist) this planetary graveyard of space probes.

Thanks, +Michael Interbartolo

Maybe it is time to start looking at our closest neighbor instead of just Mars
Venus has had plenty of time to evolve life on its own," explains Limaye, noting that some models suggest Venus once had a habitable climate with liquid water on its surface for as long as 2 billion years. "That's much longer than is believed to have occurred on Mars."

On Earth, terrestrial microorganisms—mostly bacteria—are capable of being swept into the atmosphere, where they have been found alive at altitudes as high as 41 kilometers (25 miles) by scientists using specially equipped balloons, according to study co-author David J. Smith of NASA's Ames Research Center.

Stories | Science fiction | +T.E. Mark

If it's by T.E. Mark, the science will be solid, or at least plausible. So even an edge-of-impossible thing like the Sun dimming and Pluto running off would make some kind of sense in his book.

Since I haven't read it myself yet, here's a review from Amazon to help you make up your mind:

Nicely told story of a catastrophic event and the aftermath for the survivors of the planet Earth.
This novel, written much like a film script, is an extremely well-written story of a catastrophic experiment gone wrong with the Earth, and the entire universe, facing imminent doom.
The characters are real - the science is well articulated and just enough to make it seem plausible, and the screenplay pace keeps you turning pages long after you wanted to stop.

Mr Mark did a fine job with this book, and I will certainly be looking forward to a follow-up as the scene is set for a sequel. Or two or three.

Physics and materials | Water

So, why does water have all these anomalous properties as a liquid?

Via +rasha kamel.

#Physics #Materials #Water
"The properties of water have fascinated scientists for centuries, but yet its unique behaviour remains a mystery.

Published this week in the journal Proceedings of the National Academy of Sciences, a collaboration between the Universities of Bristol and Tokyo has attempted a novel route to understand what makes a liquid behave like water.

When compared to an ordinary liquid, water displays a vast array of anomalies. Common examples include the fact that liquid waterexpands on cooling below 4 C, which is responsible for lakes freezing from the top rather than the bottom.

In addition, the fact that water becomes less viscous when compressed, or its unusually high surface tension, allows insects to walk on water's surface.

These and many other anomalies are of fundamental importance in countless natural and technological processes, such as the Earth's climate, and the possibility of life itself. From an anthropic viewpoint, it is like the water molecule was fine-tuned to have such unique properties.

Starting from the observation that the properties of water seem to appear fine-tuned, a collaboration between Dr John Russo from the University of Bristol's School of Mathematics and Professor Hajime Tanaka from the University of Tokyo, harnessed the power of powerful supercomputers, using computational models to slowly "untune" water's interactions.

This showed how the anomalous properties of water can be changed and eventually reduced to those of a simple liquid. For example, instead of floating on water, the density of ice can be changed continuously until it sinks, and the same can be done with all water anomalies.

Dr Russo said: "With this procedure, we have found that what makes water behave anomalously is the presence of a particular arrangement of the water's molecules, such as the tetrahedral arrangement, where a water molecule is hydrogen-bonded to four moleculeslocated on the vertices of a tetrahedron.

"Four of such tetrahedral arrangements can organise themselves in such a way that they share a common water molecule at the centre without overlapping.

"It is the presence of this highly ordered arrangement of water molecules, mixed with other disordered arrangements that gives water its peculiar properties".
