The gravity is really low you could probably use a cold gas thruster to get off the surface.

>>8993507
it would still be worth it

it has less gravity than our own moon

Time isn't real

The thing to understand here is that time is a "real" thing. It's not an illusion, it's not a human invention. It's a discovered property just like distance or mass.

We can observe the physics of slower time, too! Imagine an unstable particle launched from the sun at a really high speed. In fact, this speed is so fast that the particle experiences half the time that a stationary observer experiences. If the particle has a half life of 1 second, and 500 particles are launched from the sun at a detector, and the stationary observer sees the particles hit the detector 2 seconds after being launched, how many particles will the detector detect?

The answer is 250. Even if we saw 2 seconds pass, the particles only saw one second pass, so they only reduce by 1 half.

and since photons are going at C they experience no time. from their perspective they are absorbed the moment they are created

A common brainlet excuse, not so common in reality though.

Possible, but 99% of the people who refer to themselves as smart but lazy are brainlets.

t. smart but lazy

Because they're made of electreecity.

I took a course with this textbook as well. Was a discrete math course at UC Davis. Not gonna lie, it was stupidly easy and the final amounted to some logic puzzles (the tower of alexandria was one of them)

what's the most valuable degree? theoretical physics?
https://www.tcd.ie/courses/undergraduate/faculty/#F02

What's the best text to learn measure theory? I have a copy of Folland

I don't know if this is relevant here, but this is a medicine related question.
Last year around this time I got tested for about a million allergens since I had, for the first time in my life, a runny nose and itching eyes for no reason.
The tests came up with nothing, and it quickly went away.
Now, I'm experiencing the same damn thing. Anybody have any idea what it could be?

>>8989147
>Bionic eyes that can see in the dark.
Hmmm.... surgery or flashlight?

>Super strong bionic arm that can bench press 500 lb.
Why would you need to bench press 500 lbs? It's not like you will impress anyone since you didn't get it done with hard work in the gym.

>Photographic memory implants.
Hmmm.... surgery or google glass?

>>8989160
Surgery. The augmentation is fused with your cells.

>>8989161
>The augmentation is fused with your cells.
And why is that good? You can either have external technology which can always be easily gotten rid of and replaced with better technology, or get surgery every year. Being implanted in your body is almost always unnecessary.

you wouldn't believe it anyway

>High School Biology
Teacher was unfuckingbelievably left wing biased. She had fucking "wage gap" related signs and shit plastered all over her classroom. Single strictest teacher I've ever seen, wasn't strict as in actual learning, she just hated children. Would spend multiple class periods talking about how great her environmental work is. One of her assignments was literally to go outside and pick up garbage and another was to go into the desert to gather plants and spend weeks drying and pressing them, except if it was a non-native plant she'd toss it out and you had no way of knowing if the plant was native or not. She spent huge amounts of time shilling her ecology class and made impressionable kids watch super biased vegetarian/environmentalist shit. She was also the sex ed teacher and required everyone to have fake gay sex for an aids demonstration, I backed out and I was the only one with aids because she gave me the aids cup. I went from fucking hardcore die hard democrat to full 1488 in one fucking school year thanks to her.

>High School Pottery
Unironically named Mr. Waddles, looked like a fucking lanky pug. Outright hated students, was full of arbitrary rules that made zero fucking sense. Once accused me of cheating because I studied for a test and got all the answers right. He spoke entirely in catchphrases and would unironically start rapping in class. At that point I just stopped caring so I made all my clay into dinosaurs, which he threw away and started sitting next to the door because he would wait 30 seconds to let everyone out after the bell rang without fail. He'd send me into a nearby teacher's class who was really fucking cool. Finally got to switch out after he gave me a referral for eating beef jerky in class. I know it sounds like I was being a little shit but this was just after the biology teacher and I was just couldn't deal with that shit for another year.

Post high school has been completely fine, just have to check on the teacher

I wish I was based enough to fart in front of students.

That would be hilarious if the last balding, fat, low IQ people are Gen Z, and they have to live like lepers among the ubermenschen.

>Is it possible to cure balding with CRISPR?
CRISPR and transplants, yes.
>(Are you balding?
Yes, starting to.
> Have you accepted it?)
No.

>>8997495

Just save up for a transplant

Pretty much. The established formula was [math] p = mv [/math] and as m=0 then naturally p=0 (if you know your math) but having everything solved means no grant money, nor no popsci money. Therefore physicists now have to invent some kind of special case around everything to still make money.

It is pretty sad if you ask me. Physics is literally useless nowadays. Just a bunch of scam artists.

>>8997481
p/m=v
For limit m ->0, v goes to infinity.

Einstein is a Fraud & Plagiarist.

Special Relativity was discovered/created by Lorentz & Poincaré
General Relativity was discovered/created by Carl F. Gauss, Bernhard Riemann & Ernst Mach.

Einstein just Plagiarized/Copied from them.

Im not arguing that the new show is a shill show. But the idea of gender being a spectrum has been around for a while.

https://en.wikipedia.org/wiki/David_Reimer

this is the best scientific explanation for it.

No, no you didn't. You are a /pol/tard angry that your only discussion topic already died out.

It's time for you to go back.

gender identity being a large part learned makes sense, but why do people describe personality differences as "gender identities". seems like it would just confuse young people and lead to depression of the kind referenced in that wikipedia article.
