One day, while working on a website, I was wondering how to calculate a specific point in a graph. After googling, the answer was by using sine and cosine. Mind blew away, I had always thought I’d never use them.

It will never take 1 year for 15 launches… Also HLS will be ready before astronauts are sent to the lunar orbit.
You clearly don’t and refuse to understand how SpaceX works. Your arguments show how little you understand any of it and using “lmao” at the end of your wrong arguments to prove how good they are is completely ridiculous.
I will watch your video because I’m always curious to understand other viewpoints and learn things, but I’m not planning on replying any further.
Fully reusable falcon 9 have been scrapped a very long time ago because they realized it wasn’t the right hardware for that. Starship will be and way way more capable. The test flight that exploded never intended to survive. Hoped? For sure. Intended? Absolutely not. It was a test prototype, not a rocket in the sense you make it.
Turnaround for space shuttle was 54 days at best before the explosion of challenger, 88 days since. Falcon 9 is down to 32 and keeps going down. 32 vs 88 is not almost the same. Second stage will never be reused neither will parachutes on Dragon landing. SpaceX wanted propulsion landing, NASA refused. One day they might change their mind (NASA) with starship.
You keep pointing at possibilities that might have been discussed or even said at some points, and I understand your frustration, but none of these were signed deals, they were possibilities or goals to try to achieve while developing the technology, then realising a better solution works (like catching the fairing halves vs. grabbing them from the ocean).
The timeline that’s over confident is for the sales pitch, that’s for sure.
Sources are from Wikipedia articles for both starship and Orion as well as an article from the planetary society on the cost of SLS.
The trajectory was chosen by NASA because the Orion capsule on top of the SLS rocket do not have enough efficiency to be on a low regular lunar orbit while landing and bringing back astronauts. This trajectory has nothing to do with SpaceX.
When comparing the one rocket to land on the moon to the 15 launches (thank you for writing launches and not rockets, as Destin Sandlin wrongly did) is because the mass delivered to the surface is gigantic compared to Apollo. Why? Because we do not want to say “we did it!” We want to say “we live there!”.
Can people stop saying SpaceX rockets explode? They do not. Super rarely they have, but that’s not something that happens on a regular basis and happens as rarely to all other companies. Explosions are either caused by landing first stages (nobody does that, the mission success, they are pushing the limits to reuse parts and they haven’t exploded in a very long while, while adding capacity no other company has) and prototypes that are meant to rapidly test limits and new technology explode, that’s actually the goal: push further, test, improve, nice on to next new system. It’s just a completely different approach from other rocket companies. Instead of spending years and years in research and development, they spend months, test, boom, months, test, boom. What that brings is huge innovation.
When comparing SLS to Starship, check how long has SLS taken and how much it costs while looking at its capacity:
$24B for the first rocket, 4+ per next rocket
$20.4B for Orion
11 years to get the first rocket
16 years to get the first capsule
Can bring 690ft³ of payload
As of now, and evolving for Starship:
$7B cost, 4 from NASA for the first 2 missions
11 years for the first tests, still no rocket
Can bring 220,00lb and 35,000ft³ to the moon
And they still and up with a rocket NASA can continue to use at very low price (less than 25% than SLS per mission)
I remember the moment I put down the pen and thought: that’s it! Last exam ever! Never going back to university after that, it’s finally over!
That was 15 years ago and I still relish that moment.
This one wouldn’t make sense as they say dates as month day, year.
To me, dates should always be written in international format: YYYY-MM-DD
Not only province, but doctor/hospital but mostly urgency.
If you’ve got something critical, it’s super fast, otherwise it can be pretty slow.
Examples:
went to the emergency for something stuck in my eye, 3am. Went in, waited 3 minutes to be checked, saw a doctor 15 minutes later, by the 1h mark I was out with 1 nurse and 1 doctor who had seen me and removed what I had and another nurse who had given me a vaccine shot.
On my way out, I talked to someone in the waiting room I had seen at 8PM getting a softball to the side of the eye, she finally saw someone around 11h after getting to the E.R. (they quickly evaluate the urgency when you arrive).
Almost 4 years later, I’m still waiting for my vasectomy appointment.
Do you have access to food, stores, etc using public transport? How do you go about buying stuff and bringing it back home?
To me it’s the complete opposite. How can you raise children in the city? They can’t go out without a parent watching over them, they don’t even have a garden to play outside. By moving to the suburbs, my kids can just get on their bike, scooter or skateboard and meet up with their friends at their home or at the park, even as young as 8, it’s a pretty safe place and they’ve got plenty of outdoors to enjoy. We have room for the pool as well as the trampoline, playing soccer and kids can just walk to school super early.
I moved in to the city when I was 14, after growing in the country/suburbs, when you’re a teen, it’s fun to take the bus to go watch a movie with your friends without relying on a parent driving you there and back. But younger than that, take your bike and you’ve got complete freedom!
I couldn’t imagine raising my kids in the city so we moved out before having them, now I can’t imagine moving into the city ever again, I actually almost never go to the city except to visit friends or some museums, too many people, bricks and asphalt.

I tried a few EVs, I’ve tried non Tesla charging stations. I drive a model 3 and I cannot stress how awful the experience of driving an EV (or even ICE cars) is shitty when comparing to a Tesla. I really can’t see myself buying something else for the moment. The whole driving, charging, entertainment experience is a complete bliss compared to other cars.
For the exact same reason, I switched those two buttons on the switch. That’s a pretty neat feature. Except when I alternate playing with the kids who got used to the switch default buttons, I need to remap everytime but you can save and load mappings.
In Zelda you can also change the mapping, which I did so that I could run with one button (bottom one if I recall) and jump with the button next to it (right I think) instead of the top one, because it’s way easier to run and jump by simply rolling your thumb.
My headphones can pair with a lot of devices. It can actively play media from only one source at a time, though. The ability for headsets to play sound from two sources at the same time is still pretty rare. And I’m not even sure playing from 3 sources exists.

That’s sad though. Sometimes I don’t feel like replying to my friends, I know it’s the same for them. If they saw my message and haven’t replied, I assume they’ll reply later or give them a bit more time before reminding them.
I love it, it tells me either they haven’t viewed it, so no need to remind them or need to call them if it’s a bit more urgent. If they saw it and didn’t reply, depending on timing and situation, I assume/know that either they’re too busy right now, working on something before replying or forgot and need a reminder.
Super useful!
I have a different experience with EVs.
I’ve got an EV with 265mi of range and an ICE car. I almost never use the ICE car, except for 2 reasons: is a 7-seater and sometimes I need both cars at the same time. In 100% of all cases, no matter how short or long the drive is, no matter the temperature outside (I live in an area where we get all the way to -40 and multiple months below 32F/0C.
I’ve never had any problem with that. I mostly charge home, this is where I agree that it’s a lot more convenient if you have a driveway, but all new and recent constructions are required to come with EV plugs in apartment complexes, etc. More and more lvl2 chargers are being installed throughout the city. Spent 5 days at my sister in law’s in the city while we lost electricity at home, I simply charged at work during the week and one time I went to charge at the corner of the street (<2min walk) for a few hours. It was actually a lot easier than I thought it would be.
The range decrease is no real issue during winter, my day starts with 100% of range everyday and in long road trips I will stop more frequently, but only for about 15-20 min max every few hours and will cost about 10$/charge. Super simple.
I thought I’d wanted to keep an ICE car as the second one, but already I see no point in it.
The only concern I think is valid is degradation in the long run. But best EV cars have very little degradation (as you mentioned), but also we technology improves, the batteries get better and better as well as cheaper, so I believe the batteries in 20 years will be incredible compared to today’s which is already super impressive. Also the infrastructure will be a lot better. Replacing a battery won’t cost as much.
2 years with an EV now and I can’t see many reasons to use ICE cars. Only left are heavy lifters (pickup trucks who tow big trailers everyday in winter, that’s a 75% range reduction). But this will also improve.
