Lois McMaster Bujold:
Heard about the EM Drive? Invention appears to defy classical mechanics by producing thrust from energy without using propellant, which violates conservation of momentum. NASA is testing and so far hasn't managed to disprove it - in other words, continues to validate the invention. Could lead to viable space travel. http://www.nasaspaceflight.com/2015/04/evaluating-nasas-futuristic-em-drive/

Hope it works out!
Indeed, I never pictured my own stories' ships moving through Nexus normal space using reaction mass of any kind. Gravitational rowing, for all I know, but not spitting stuff out the back end at high velocity. So many problems with the physics of that.
(Yes, I know "fuel" gets mentioned, because one can't get something for nothing, not to mention "thrusters", but one should not be picturing chemical combustants.)

Lois McMaster Bujold:
I've tried to picture what a nerve-disruptor would look like, and find a conflict between descriptions of it's parabolic bell-shaped muzzle and the ease with which wielders of the weapon are able to holster and aim them. I appreciate that it would loom larger-than-life for anyone looking down the business-end of one and that most descriptions are from that perspective. How big are they really?

Lois McMaster Bujold:
So, I usually download kindle and audible files on amazon, but with the Orphans of Raspay, I can only get the audiobook through the amazon US website. It doesn't let me do that trough my local (currently German) page, which tells me there is no audiobook (i.e. https://www.amazon.de/gp/product/B07VFPQ711/ref=ppx_yo_dt_b_d_asin_title_o06?ie=UTF8&psc=1) Any idea why?
