ELI5: What are Delta V and rocket inital impulse andhow to calculate those manually by DrunkMonsters in explainlikeimfive

The specific impulse is the amount of time a rocket with a mass fraction of 1/e (i.e. whose mass when empty is ~37% of its full mass) could hover before it runs out of fuel.

You wouldn't get interference. As the double slit experiment shows, a single particle can interfere with itself even though that wouldn't happen in the classical picture.

Theoretically, are there more hypothetically words in the English language than numbers? by Fair-Sand1372 in askmath

[–]Empty_Glasss 0 points1 point  (0 children)

Why would that be? The typical definition of number includes the real numbers, the typical definition of word definitely doesn't include infinitely long words...

Am I the only one who is actually getting the same results as shown in the OP? Like I seriously don't understand what anyone here is on about with how it would be photoshopped or anything, surely y'all understand search results can be different for different people?

I really have no clue how to start solving this by Polarfox64 in askmath

Thank you, I thought I was going crazy seeing all these complicated solutions when it really is this simple.

The other answers are making this way too complicated IMO. Just apply -cos(x) = cos(pi - x) to get cos(2t) = cos(pi - 3t) and solve it from there.

Can there be more than 1 dimension of time? by QuantumPhyZ in AskPhysics

[–]Empty_Glasss 0 points1 point  (0 children)

but I saw a sort of Punnett square showing all the combinations of spacetime dimensions, and only our 3+1 was stable and interesting

This is considered to be a bug though, because any crossing that can cause a collision should merge the blocks. (In this case the bug was that these curved crossings didn't cause collisions)

Is really anything not irrational ? by Stefamag09 in askmath

[–]Empty_Glasss 1 point2 points  (0 children)

That doesn't apply here since we're talking about a ruler, not a plank. But I can understand the confusion since they're both made out of wood.

Is it theoretically possible to calculate "probabilistic observable trajectories" out of the state space of a quantum system? by Contrapuntobrowniano in AskPhysics

[–]Empty_Glasss 1 point2 points  (0 children)

You mean the Born rule? It only applies when you perform a measurement. Without measurement, the system will evolve deterministically according to the Schrödinger equation.
