By Lawrence M. Krauss – Each time we peel back one layer of reality, other layers beckon. So each important new development in science generally leaves us with more questions than answers. But it also usually leaves us with at least the outline of a road map to help us begin to seek answers to those questions.
The successful discovery of the Higgs particle, and with it the validation of the existence of an invisible background Higgs field throughout space (in the quantum world, every particle like the Higgs is associated with a field), was a profound validation of the bold scientific developments of the 20th century.
As elegant as this idea might be, it is essentially an ad hoc addition to the Standard Model of physics—which explains three of the four known forces of nature, and how these forces interact with matter. It is added to the theory to do what is required to accurately model the world of our experience. But it is not required by the theory. The universe could have happily existed with massless particles and a long-range weak force (which, along with the strong force, gravity, and electromagnetism, make up the four known forces). We would just not be here to ask about them. Moreover, the detailed physics of the Higgs is undetermined within the Standard Model alone. The Higgs could have been 20 times heavier, or 100 times lighter.
Why, then, does the Higgs exist at all? And why does it have the mass it does? (Recognizing that whenever scientists ask “Why?” we really mean “How?”) If the Higgs did not exist, the world we see would not exist, but surely that is not an explanation. Or is it? Ultimately to understand the underlying physics behind the Higgs is to understand how we came to exist. When we ask, “Why are we here?,” at a fundamental level we may as well be asking, “Why is the Higgs here?” more> https://goo.gl/UCn3w8
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

By Tom Kibasi – Neither Remainers nor Brexiters are facing up to our problems – and their failures are letting Britain down. During the referendum, Remain campaigners argued that things were fine when they were not and, since the result, Brexiters have argued that things will be fine when without serious change they will not be.
Immigration is such an important issue precisely because free movement of labor is the crucial enabler of the low skill, low productivity, low wage economic model that has been imposed on much of the country. It is this economic model – combined with the cultural and identity challenge of large-scale immigration – that has created such discontent with the status quo.
What’s more, there is nothing progressive about declining to invest in skills in this country, while plundering poor countries of nurses or doctors or carers and then approaching immigration as if people were commodities to be bought up on the open market. more> https://goo.gl/ctcTto
The Imagineers of War: The Untold Story of DARPA, the Pentagon Agency that Changed the World, Author: Sharon Weinberger.
The Manchurian Candidate, Author: Richard Condon.
The Romance of American Psychology, Author: Ellen Herman.
By Sharon Weinberger – Joseph Carl Robnett Licklider – JCR, or simply Lick to his friends – spent much of his time at the Pentagon hiding. In a building where most bureaucrats measured their importance by proximity to the secretary of defense, Licklider was relieved when the Advanced Research Projects Agency, or ARPA, assigned him an office in the D‑Ring, one of the Pentagon’s windowless inner circles. There, he could work in peace.
One time, Licklider invited ARPA employees to a meeting at the Marriott hotel between the Pentagon and the Potomac River, to demonstrate how someone in the future would use a computer to access information. As the chief proselytizer for interactive computing, Licklider first wanted people to understand the concept. He was trying to demonstrate how, in the future, everyone would have a computer, people would interact directly with those computers, and the computers would all be connected together. He was demonstrating personal computing and the modern internet, years before they existed.
ARPA was established in 1958 to help the United States catch up with the Soviets in the space race, but by the early 1960s, it had branched off into new research areas, including command and control. The internet would likely not have been born without the military’s need to wage war, or at least it would not have been born at ARPA. Tracing the origins of computer networking at ARPA requires understanding what motivated the Pentagon to hire someone like Licklider in the first place.
It started with brainwashing. more> https://goo.gl/0HwrXh

By George Monbiot – Our capacity to resist manipulation is limited. Even the crudest forms of subliminal advertising swerve past our capacity for reason and make critical thinking impossible. The simplest language shifts can trip us up.
Already big money exercises illegitimate power over political systems, making a mockery of democracy: the battering ram of campaign finance, which gives billionaires and corporations a huge political advantage over ordinary citizens; the dark money network (a web of lobby groups, funded by billionaires, that disguise themselves as thinktanks); astroturf campaigning (employing people to masquerade as grassroots movements); and botswarming (creating fake online accounts to give the impression that large numbers of people support a political position).
All these are current threats to political freedom. Election authorities such as the Electoral Commission in the UK have signally failed to control these abuses, or even, in most cases, to acknowledge them.
That’s the bad news.
But digital technologies could also be a powerful force for positive change. Political systems, particularly in the Anglophone nations, have scarcely changed since the fastest means of delivering information was the horse. They remain remote, centralised and paternalist.
The great potential for participation and deeper democratic engagement is almost untapped. Because the rest of us have not been invited to occupy them, it is easy for billionaires to seize and enclose the political cyber-commons. more> https://goo.gl/0PGihC
