>electricity and magnetism combine into electromagnetism at high energy
>electromagnetism and weak combine into electroweak at even higher energy
>electroweak and strong combine into electrostrong at even higher energy
So why do people claim that electromagnetism is a single force, while still acknowledging that weak and strong are separate forces? Surely saying that electricity and magnetism are not different things is the same as saying that electromagnetism and weak are not different things?
Why not acknowledge that electricity and magnetism are separate forces?
Is this discrepancy just for historical reasons (electromagnetism was discovered earlier than electroweak) or what?

Your screenshot mentions neither the vaccine, nor paxlovid. Also, the hazard ratios are again not different within their uncertainties.

If you compare the PhD thesis of people in the past to people in the present, the theses now are incredibly dogshit.

PhD theses back in the day used to be like reading a divine message from god. They would completely change the way you think about the world. Just look at Turing's thesis. Holy shit. It's life-changing. You will become a chad if you read his thesis.
Even worse, these people are now teaching undergrad courses. They are bringing their arrogance and their "expertise" to the classroom and think they actually know something. Once you start testing their actual knowledge, they start to falter. They don't know basic shit. This is stuff you learn in the first few years of grad school and they can't even give you a coherent answer. These people are an absolute joke. Why did we let this happen?

>wing generates lift because... because air going above and below it has to take the same time to do it so it has to go faster on one side and so it creates pressure differential
>why does it have to take the same time?
>it... it just does, okay??

No shit Sherlock.
The Merlin went through multiple iterations over the years before it became a mature rocket engine and the same applies to Raptor.

Unstable, undergoes a phase transition if you simply sneeze around it.
>gallium arsenide
Too expensive.
>cadmium telluride
Low efficiency and huge pollution issue, very toxic heavy metals, not sustainable.

You are picrel, along with all the other solarnormies.

I would love for BO to contribute to spaceflight more but just saying it won't change the reality.

I like to wonder if heavy sleep deprivation remote viewing in a sensory deprivation tank has been done before sometimes.

Lmao you mean last 30 years of dev work right?
The last exclusively Boeing made rocket, the Delta III, exploded twice with satellite payloads for its first 2 test flights, and partially failed it's third flight with a dummy payload, by launching into the wrong orbit, then the program of was cancelled, in that time they par made a rocket through ULA that's not complete shit, but expensive, failed to test fire SLS, and delayed that test fire for 6 years, and failed building a capsule, that currently still hasn't been successfully tested lmao

I am in first year of engineering and I fucked up at the last two tests. Chemistry and statics. Guess the percentage.
