Launch times draw near for Aalto satellites
By Jaan Praks – The Aalto-2 satellite, designed and built by students, is ready and waiting to be launched inside the Cygnus space shuttle at the Cape Canaveral Space Launch Complex in the US.
On 22 March, the shuttle will be launched with an Atlas V booster rocket up to the orbiting international space station, where the astronauts will release it later to orbit independently.
Aalto-2 will take part in the international QB50 Mission, the aim of which is to produce the first ever comprehensive model of the features of the thermosphere, the layer between the Earth’s atmosphere and space. Dozens of satellites constructed in different countries will also be part of the mission.
Construction of the Aalto-2 satellite began in 2012 as a doctoral project when the first students graduated as Masters of Science in Technology after working on the Aalto-1 project.
Since the start of the Aalto-1 project in 2010 and the Aalto-2 project two years later, around a hundred new professionals have been trained in the space sector. The impact is already visible in the growth of space sector start-up companies. more> https://goo.gl/yKLrez

Four-Stroke Engine Cycle Produces Hydrogen from Methane and Captures CO<sub2
By John Toon – When is an internal combustion engine not an internal combustion engine? When it’s been transformed into a modular reforming reactor that could make hydrogen available to power fuel cells wherever there’s a natural gas supply available.
By adding a catalyst, a hydrogen separating membrane and carbon dioxide sorbent to the century-old four-stroke engine cycle, researchers have demonstrated a laboratory-scale hydrogen reforming system that produces the green fuel at relatively low temperature in a process that can be scaled up or down to meet specific needs. The process could provide hydrogen at the point of use for residential fuel cells or neighborhood power plants, electricity and power production in natural-gas powered vehicles, fueling of municipal buses or other hydrogen-based vehicles, and supplementing intermittent renewable energy sources such as photovoltaics.
Known as the CO2/H2 Active Membrane Piston (CHAMP) reactor, the device operates at temperatures much lower than conventional steam reforming processes, consumes substantially less water and could also operate on other fuels such as methanol or bio-derived feedstock. It also captures and concentrates carbon dioxide emissions, a by-product that now lacks a secondary use – though that could change in the future.
Unlike conventional engines that run at thousands of revolutions per minute, the reactor operates at only a few cycles per minute – or more slowly – depending on the reactor scale and required rate of hydrogen production. And there are no spark plugs because there’s no fuel combusted. more> https://goo.gl/h4K7fV

The Pearly Gates of Cyberspace, Author: Margaret Wertheim.
Physics on the Fringe, Author: Margaret Wertheim.
African Fractals: Modern Computing and Indigenous Design, Author: Ron Eglash.
By Margaret Wertheim – The world is full of mundane, meek, unconscious things materially embodying fiendishly complex pieces of mathematics. How can we make sense of this? I’d like to propose that sea slugs and electrons, and many other modest natural systems, are engaged in what we might call the performance of mathematics.
Rather than thinking about maths, they are doing it.
In the fibers of their beings and the ongoing continuity of their growth and existence they enact mathematical relationships and become mathematicians-by-practice. By looking at nature this way, we are led into a consideration of mathematics itself not through the lens of its representational power but instead as a kind of transaction.
Rather than being a remote abstraction, mathematics can be conceived of as something more like music or dancing; an activity that takes place not so much in the writing down as in the playing out.
Since at least the time of Pythagoras and Plato, there’s been a great deal of discussion in Western philosophy about how we can understand the fact that many physical systems have mathematical representations: the segmented arrangements in sunflowers, pine cones and pineapples (Fibonacci numbers); the curve of nautilus shells, elephant tusks and rams horns (logarithmic spiral); music (harmonic ratios and Fourier transforms); atoms, stars and galaxies, which all now have powerful mathematical descriptors; even the cosmos as a whole, now represented by the equations of general relativity.
The physicist Eugene Wigner has termed this startling fact ‘the unreasonable effectiveness of mathematics’.
Why does the real world actualize maths at all? And so much of it?
Even arcane parts of mathematics, such as abstract algebras and obscure bits of topology often turn out to be manifest somewhere in nature. more> https://goo.gl/ifKV2Z

By Daniel L. Byman – Let’s consider some of the assumptions Trump and his team appear to bring to the table as they enter office. Some are about how the world works, while others concern the best way to design and implement U.S. foreign policy.
- Assumption #1: Calling it “Radical Islam” Makes a Difference
- Assumption #2: Foreign Public Opinion Doesn’t Matter
- Assumption #3: Allies are Overrated
- Assumption #4: Russia Is America’s Natural Partner
- Assumption #5: Israel Can Do What it Wants
- Assumption #6: The Rough Stuff Works
- Assumption #7: Tough Policymakers Make for Tough Policy
In short: Trump’s foreign policy assumptions fly in the face of many traditional U.S. policy approaches and the preferences of powerful bureaucracies. We should expect international realities and bureaucratic obstacles to obstruct, or at least water down, some initiatives, while those that get through might not just fail but may leave the United States worse off for pursuing them.
As a candidate, Trump excelled at destroying truisms about how politics works; over the coming years, we will find out if this holds true for foreign policy as well. more> https://goo.gl/PVWnOe
