Why don't you tell us the exact date when BFR flies, or better yet, when FH flies.

Raptor has never been tested. Only a prototype. They don't even have a fucking final design yet let alone some tests run.

Hard to find but a lot of propulsion team went to Blue both by being actively pursued by Blue and being burned out by constant grind.

BE4 is more than twice the physical size but it is a very low pressure conservative design for a staged combustion engine 2400 kN vs 1700 on new Raptor but Raptor being operated at 20 MPa goes to 1400 while blue does 1200kN at the moment and Raptor is surprisingly mature at the moment.

Blue has basically unlimited funding and they work with no worries about this.I know how finance work and that Bezos can't just pull out 50B at a moment notice but he is 4x richer than Musk at the moment and Amazon has incredible cash flow while Tesla survives on capital raises for the past few years.
They could rush and build a much bigger booster over the next 10 years spending 20B to do so if they plan to spend around 2B for New Glenn.

>>9246042
>>9246042
>FFSC is a much lower-stress cycle than ORSC, moron, that's what makes it easier.
This is why Raptor is pushed to 25-30 MPa while BE4 stays at 13.4MPa for easier reuse.
While BFR is designed on the edge of possible performance New Glenn is a very conservative rocket outside of it's immense size nearly 3x the size of Falcon

Ok, I'm having a retarded argument with some nerds in a general about "stealth" in space, so let's discuss...

Would it be possible to conceal a spacecraft in space? What would be require to do so? Forget whether or not it's feasibly possible in the modern day, I want to hear arguments for what could be and the issues involved, if any. Granted no one really knows what the future holds, but the theory is interesting.

Decoys will be a BIG thing, its essentially impossible to tell a decoy from a real thing from 1000+ miles away
Perhaps firing the engine in all directions to throw a "cloud" around the vehicle, obscuring it
Doing a burn in erratic pulses
Low thrust ion drives that are invisible
dnno predictions about how things will be in 100 years will always be totally wrong.

Perhaps they will do powerful active sensor sweeps before engaging their drive to clear nearby space of enemy sensors

Yeah you're right anon, but do you know why there are no all-black spaceships? Because that would be a thermal nightmare. We paint spaceships white because it reflects more energy, and even then they typically perform thermal roll maneuvers to make sure no part overheats.

They know they're not the real thing. It alleviates the dysphoria in a lot of trannies. They look how they think they should look. They're happy with their body image. A lot of other trannies want more though. I mean, most, if not all trannies do, but being close isn't enough to satisfy their identity crisis, sometimes exacerbating the problem.

It's like getting to the World Cup with high expectations and being shut out 10-0. Some would absolutely anguish ovet such a humiliating defeat, others are content with being on that field in the first place, the outcome of the match irrelevant in their eyes.

The word "treatment" is already a loaded term. You're implying you're treating a problem. You shouldn't argue whether "transgenderism" is a mental illness or not, but you could argue whether it's an issue for someone or not.
Therapy tries to modify a person on aspects that have been subjectively deemed illnesses.

Now why would you say that? I'm honestly not sure. Therapy works on issues we've deemed psychological, but we've deemed them psychological because there's no obvious physical treatment. (when for all you know the cause could be a brain tumor) This is all pretty circular.

The Many Worlds Interpretation of QM is now commonly accepted among physicists. As far as I understand it, that means that every possible universe exists and their distribution is fixed.

If I decide to take in and take care of a stray cat, there will be another universe in which I don’t. If I decide not to take in the cat, there will be another universe in which I do. No matter what I do, there will always be a stray miserable cat and a happy cat with a roof over its head. What I do doesn’t change the amount of “suffering” that exists, because its distribution is fixed. The only thing that can be determined by my actions is what I perceive in this universe.

Doesn’t this destroy any sensible notion of altruism beyond selfish incentives?

a playout is just a random game started from a certain state, right? MCTS estimates the value of each state by playing many random games keeping track of how often a random game results in a win from any given state.

so yeah, a playout isn't really a tree search in and of itself, but aren't playouts the defining feature of MCTS.
>>
>>9246047
The MCTS does not rollout to the end of the game. It's only a limited depth, I think.
>>
>>9246058

that's not really MCTS then...
>>
>>9246063
I guess, that's what they were doing in the previous versions of alphago though.
Limited depth search then use one of the NNs to evaluate the board.
They've combined the two NNs into one in this version, so I'm not sure how it works.
>>
>>9246067

MCTS makes up for the lack of an accurate value function, as i understand. if they have a good way to measure the value of any given state, then it would make sense that random playouts are unnecessary.

What are some /sci/ ways to generate renewal of ecosystems? Is it all just down to planting trees and proper soil management?

So I was wondering while studying for medicine exams, is it possible to combine 2 molecules or antibiotics (Lets say Penicillin and Cephalosporin) and get a superantibiotic? Of curse we would have to protect the pars of molecules which are meant to connect to PBP so they would work.

Thoughts? And if you have an answer, please leave a citation or a link to proof, if you have any.

Almost all the new antibiotics are just modifications/new gens of original antibiotics. There haven't been any actually new ones in years.

http://www.who.int/mediacentre/news/releases/2017/running-out-antibiotics/en/

It's expensive, they can't be toxic and standards are getting higher all the time for the amount of human risk that can result and pharm companies would rather invest money in drugs that will need to be taken multiple times for the rest of a patients life than a solution like antibiotics that will stop being used within a very short time.

Worst comes to worst we're probably just going to use antibody therapy. It's just slow as fuck to produce.

I don't know how to explain why it won't work other than saying that your intuition of biological chemistry and metabolism is somewhere between flawed and flat-out wrong. Even if you attached the two units by a long, thin string, so that almost no blockage occurs around one specific part of the molecule (presumably derived from a functional antibiotic), this COMPLETELY changes everything about the drug's solubility in and permeability through membranes and extracellular / intracellular spaces. Having a drug "fit" in the right spot is probably around 10% of the battle in drug discovery. Maybe 50% in only the most extreme cases. There are many different variables that have to be simultaneously tuned to produce efficacious, and more importantly SAFE, drugs. Cyanide is a fantastic antibiotic, but it'll kill the host when prescribed in "therapeutic" doses. Likewise there have been probably thousands of compounds shown to have amazingly powerful potential as drugs for all kinds of problems in trials with bare cells in a lab, but they never make it to being effective "drugs" because they are metabolized before they can do anything or never get where they need to go in the first place.
