Against adversity, give Greek research breathing space

In Greece, we have been witnessing a violent socio-economic restructuring due to the austerity measures introduced in response to the economic crisis, over the last three years. These measures, dictated by the so called “Memorandums for Economic Stability”, have been applied horizontally and indiscriminately and have led to deep economic recession and high unemployment today reaching 26%. It is therefore inescapable; the scientific community too has been affected.

European airspace – acting as one

The lonely scientist, covered by his papers alone in his room, talking to no one, is extinct. Science happens world wide in connection with partners around the globe, frequent travels are part of the daily life. Like for anybody else, delays are quite an annoying concomitant, especially if you travel by plane to reach your destination faster. Very often in Europe the cause for a late arrival is Air Traffic Control (ATC) related.

Is Europe in the space race?

There are a surprising number of European countries with space programmes, especially if compared to the days of the cold war when the US and USSR led the race. Germany (DLR), France (CNES), the Netherlands (SRON), Norway (NSC), and Sweden (SNSB) all have current projects underway, as well as the umbrella pan-European organisation, ESA, which has 18 member states and six cooperating states, which includes, interestingly, Canada.

Black holes as rejuvenating systems of the universe

Jets from the black holes in the centers of some galaxies are well documented by astronomical observations. The mechanism that forms these jests is not well-understood yet. We extended the mass-energy equivalence principle to the universal space where a given physical object diminishes the energy density of space in its center exactly for the amount of its energy. In today’s physics is understood that universal space is a type of energy often named “superfluid quantum space”.

Self Sovereign Identity can do just fine, blockchain-less

Authentication is the big problem on the Internet. There is no portable authentication layer in the Internet protocol, like phone number portability between phone providers. This has been a problem since the beginning: how do you prove that a user or other entity is who they say they are? Authentication is also the basis for the term SSI or self sovereign identity, popular in policy documents today. How can you control your own online identity? And at least as important: how can you ensure that others do not abuse it?
