> A comparison across established propulsion concepts clarifies the technological significance of each mission architecture. The 226-day configuration (56 + 35 + 135 days) lies nearer to the boundary of what advanced nuclear-thermal or high-performance electric propulsion might plausibly achieve in the coming decades. In contrast, the 153-day configuration (33 + 30 + 90 days) demands departure and arrival energies far exceeding the performance envelope of any current or near-term propulsion technology; it is therefore interpreted not as a realizable mission, but as an upper theoretical limit defined by the CA21-anchored geometry.
Speaking of ways to - rightly or wrongly - veer off on a tangent, and convince large numbers of people that the anti-Big Brother side is unhinged...
A better counter argument to "catch the pedo" is to bring up cases of creeps who were insiders - law officers, or just techies with access - and used the "well-intended" tech to get at their victims.

Certainly. You mean like that time an Israeli Cyber Directorate division chief fled Nevada for Israel after being investigated for soliciting a minor for sexual purposes?
Populations are large. You can draw a pattern in any population.
I think if I were saying this to convince people that hardware freedom is a good idea, they might think I care less about hardware freedom and more about memorising evil Israeli people to make sure I always have a negative example of an Israeli to mention in conversation.
My recollection is that decision was a straight-up "success is irrelevant, HM Treasury has decided that the UK cannot afford to have an orbital launch program".
From the timing, one certainly could speculate that the needed pounds were being squandered on other programs - ones given higher prior, but less-competent leadership.
Old family story: Back in the 1920's and 1930's, one of my cousins (a bit removed) was a poacher in rural northern Michigan. Everyone from the County Sheriff on down knew that she was a poacher. Everyone also knew that she was a widow with several children, living in (even for the place and time) grim poverty, and the she was poaching to feed her children.
As kids, we were told more details - both to know about our extended family, and to support various lessons about poverty and charity and pre-WWII rural communities.
But one of the more subtle lessons was that "the law" and society's actual rules are, at best, overlapping circles on a Venn diagram. No matter what lawmakers, those invested in the legal system, and those telling simplistic stories to children might say.
It doesn't matter what fancy tech you have, or how much money, or anything else - if the people you have making the decisions and doing the work either are shit, or they go to shit, then you'll never be able to produce much beyond expensive steaming heaps.
And just how far Britain has fallen, over the past 6 to 12 decades, strikes me as one of the great tragedies of Western history. );
Not to argue technical details, or say that Poland's ABW should keep incidents secret - but both the content and tone of this sort of article strike me as almost designed to teach defeatism and despair. Maybe the good guys could occasionally mention that they're (say) paying to replace obsolete/unpatchable computer kit at their nation's water treatment plants, or starting to scan their own nation's critical infrastructure for default passwords, or whatever?
(Or if nothing useful is actually being done - perhaps some Polish journalists could start asking opposition politicians about what they'd do, if they got into power? That might even spur a few incumbents to action...)
The "logic" of xenophobic nationalism is that narratives are selected for how well they (1) cast "us" as victims, (2) cast some convenient "others" as villains, and (3) fire up "our" feelings of hatred. Neither logic nor truth are particularly desirable - and narratives which are particularly defiant of logic and truth may be a way of virtue signaling within xenophobic national social circles.
Generally true, but the school's core protection responsibility is for its own students and staff - not the rest of the world. And the school's authority and resources are even more constrained.
At least in some places, school systems have "special" schools or other programs for the kids who they'd rather keep out of contact with the general student population.
Not sure how it is overseas - but in the US, the #1 problem with Visa/MC is the huge percentage that they skim off every transaction. Businesses running on tight profit margins often give a discount if you pay with cash instead.
I think the fees are on order of 1-3% depending on your risk and business type. Certainly an issue but it's mitigated a bit by the decreased costs of going cashless. I.e. cashless operations avoids theft by employees; overhead for stocking, counting, and handling money; reduced insurance due to less chances of robbery; etc.
Vs. the research paper - https://www.sciencedirect.com/science/article/pii/S009457652... - is perfectly honest about its proposed trajectories scoring 0 for 3 on "shortcut", "secret", and "ultimate". Their summary of the delta-v requirements:
