@BjornLomborg@jordanbpeterson Although the long-term data is probably not available, the effects of contraception on population decline and aging populations is concerning. It is probably best to investigate this before promoting contraception. There’s no point in a rich country if no one is being born.
@DonutOperator The most important thing is to build interest and passion for a direction in life. School work is useless unless there is a purpose for it, and if there is a motivating purpose, school work will become a breeze. Help the kid find his passion before doing any actual school work.
Starlink has been told by some governments (not Ukraine) to block Russian news sources. We will not do so unless at gunpoint.
Sorry to be a free speech absolutist.
I'm in the US for the first time in 2 1/2 years, and talking face to face with people is immensely more productive than talking over Zoom. If Zoom were the default and someone just invented face to face, it would seem like an amazing step forward.
The University of KwaZulu-Natal's Aerospace Systems Research Group (ASReG) has successfully tested a powerful liquid propellant rocket engine as the first step towards developing a launch vehicle for placing satellites into Earth orbit. @UKZN#itspossible https://t.co/7SADZDAmcY
The paper "Metal additive manufacturing in aerospace: A review" is officially accepted and published as of today! A huge thank you to all of my co-authors, I am incredibly grateful for all your excellent inputs and hard work. This…https://t.co/zNkWXYqJmd https://t.co/NEgWZXUFOp
@SpacecoastPix@torybruno No one has tried using additive manufacturing techniques, specifically direct energy deposition (DED), at this scale before. These technologies are very new and are seeing high rates of development - only time will tell but they could be very disruptive
@stivinet @torybruno Additive manufacturing is being tested/used on almost all in-development rocket engines and even on some legacy engines. For example, SpaceX’s raptor engine is roughly 40% by mass additively manufactured
@timcortesi @stivinet @torybruno Relativity space is using Direct energy deposition (DED) methods to build their tanks. This process generally has accuracy and minimum feature size issues at the small scale, but large scale parts have more potential - defiantly a company to watch
@flylinuxinspace @astroride2000 Imo there should be 3 categories for spacefarers:
Space tourists - you go for a joyride in space
(Needs new term) - people who work or live in space with not much training
Astronauts - highly trained with in-depth knowledge of craft and safety systems
@flylinuxinspace @astroride2000 It is much more than this. Astronauts are often engineering/stem graduates and have a lot of flight hours as experience - although the latter is not so important anymore.
@gregoryasmith@elonmusk@KerbalSpaceP What phenomena causes these electric arcing issues?
I imagine that these space tethers would be placed far outside of the atmosphere so that they lose as little momentum as possible. They are not for raising craft out of the atmosphere, only energy transfer in orbit
@elonmusk@KerbalSpaceP If KSP2 includes capabilities of designing/testing space megastructures such as skyhooks, I would personally spend hundreds of hours optimising planet to planet transportation mass transfer using skyhooks
@elonmusk@KerbalSpaceP Skyhooks are an interesting concept for this, they effectively act as rotational energy storage devices in orbit. Kurzgesagt has a video describing the uses of this technology:
