/sci/ - Science & Math

Incredible day

After democracy took over the world in the 1930s-1940s, no real science was published anymore.
All modern science is either a ponzi scheme or an outright lie to access jobs or academic positions.
The last scientists were the ones of operation paperclip era, and they mostly died in the 1970s-1980s.
Prove me wrong.

Anons I have solved the anti spaceoid problem.
J*urnalists, tw*tter literal who's, envirofags, astr*nomers, YouTube grifters, all of them. They simply sign a declaration blacklisting themselves from ALL space travel, LEO trips, Moon visits, even blorogin suborbital 2 minute wonders. Their names go on record and are permanently denied the gift of ever leaving this gravity well if they are so convinced that Starship and it's successors wont work

Total astronomer death

Basically our rockets are super cheap because we deliberately ride close to the edge of tolerances to save on materials costs, which improves performance because lolrocketequation. If we make them stronger to reuse them they get more expensive. Falcon 9 basically pulled that mass margin out of its own ass with the ridiculous upgrades the Merlin got - remember it started as an expendable design. RP-1, LOX, and aluminum are all real fucking cheap compared to giant lithium batteries, pumps, and combustion chambers, so Rocket 4 is going to cost less than Rocket 3 despite being bigger.

And thanks.

Nothing a bit of pile drilling and concrete pouring can't fix.

>Beim später entwickelten Hauptstromverfahren wird das Prinzip des Nebenstromverfahrens dahingehend variiert, dass ein größerer Teil oder der gesamte Strom einer Treibstoffkomponente einen Gaserzeuger durchläuft und mit einem sehr kleinen Anteil der anderen Komponente unstöchiometrisch reagiert.
>Es entsteht so ein Heißgasstrom, welcher noch große Überschussmengen von nicht umgesetztem Treibstoff oder Oxidator enthält, der nach dem Antreiben der Arbeitsturbine der Turbopumpe direkt in die Hauptbrennkammer geleitet wird und dort an der regulären Verbrennungsreaktion zur Schuberzeugung mit den restlichen dort eingespritzten Komponenten teilnimmt.
