Mmm, am hungy.

yeah, actually; living your life in a way that minimizes the heartbreak of losing people is optimal

Bach is by pretty much all measures one of the greatest classical and non-classical musicians and coposers. Calling him pleb is just petty elitism and obscurism.

And super wasteful.

They could have saved a lot more mass on the lander.

Behold: the Open Cockpit Concept.

He was a member of our Science Bowl team that got to nationals, too.

Do we know each other? Are we both talking about Aaron?

Keyword: slowly. Mars lost that water and atmosphere over a period of a few billion years.

A lot of the time, they're really not. They reasoned themselves into their position and have constructed enormous, elaborate proofs and evidence of it. They're just incapable of escaping their logical feedback loop, because their elaborate world model also includes reasons why all opposing evidence is inherently untrustworthy.

It's some kind of failure mode in human reasoning, that lets people splinter off into these huge logical feedback loops that reinforce themselves by inventing or inflating confirmational "evidence", and discounting negative evidence, so that no matter how far they are from consensus reality, they cannot escape. Smart people are vulnerable too - to someone with a strong reasoning ability and excessive willingness to examine new (even obviously false) ideas, these kinds of loops can easily become contagious.

That's not what he's doing. I don't think you understand him correctly. Schrödinger was only explaining why his original \psi-charge density interpretation is inconsistent, and to be replaced with something else, but definitely not the theoretical description of QM at the time. He never took any instrumentalist/anti-realist view and he never, ever sided with the Copenhagen school. He was repeatedly ridiculed by them for this.

Engineering students survive on a hybrid form of sarcasm, apathy, and empathy. As well as cum.

An engineer was mistakenly thrown to hell. On getting there, he notices that things weren't comfortable. So he made some changes like installing air conditioning, safety rails, entertainment systems, the works.
Later God calls Satan and asks 'how is hell these days?' and he said 'hell is fine, in fact I have been enjoying this engineer you sent. He has made a lot of changes here.' and God said 'no, that was a mistake, send him back' but Satan refuses, saying 'no, loves sucking my cock'.

How many engineers does it take to change a light bulb? No one knows, they're too busy sucking cock.

Did you hear about the constipated engineer? Neither did I.

A mathematician, a physicist, and an engineer were all given a red rubber ball and told to find the volume.
The mathematician carefully measured the diameter and evaluated a triple integral.
The physicist filled a beaker with water, put the ball in the water, and measured the total displacement.
The engineer thought the red ball looked very much alike a glans and took it up the ass.

Real Engineer couples consider themselves well dressed if their cocks match.

Of course not. But the stereotypical vegan is like that, and that stereotype is STRONGLY established.

I, personally, like to give people the benefit of the doubt, but you can only do that so many times before you just expect every vegan to be the worst kind of stereotypical hipster shit.

...if chipmakers were stupid enough to keep using conventional techniques. Fortunately there are several different technologies being developed for the next stage.

Sure, there probably will not be drexlerian nanotech in a decade, but have you seen what biotech has been doing in the last five years? It already IS science fiction level.

>It values logic experimentation, and thought provoking question among other things

There is shitty reasoning all over /sci/. Lots of people here don't value logic much.

There are thought provoking questions on /sci/, but they're not the valued ones, and they're not that common. The valued questions are the trolls. Just check the front page.

Don't delude yourself into thinking /sci/ is a great place for science discussion. You'll have lowered your standards for what is great discussion.

For example, look at this guy >>6125907
who doesn't really understand what OP is asking. He's just talking shit because he thinks he's smart, but he can't into basic reading comprehension. That characterizes like 10% of /sci/ posts.

Also, you seem like a fedora tipper.

Well, I don't see it as much of a problem, since the laser sail is the more known form, and it's almost never called just 'laser propulsion', but as 'laser-assisted solar sail' or similar specific name.

When people say 'laser propulsion', it's generally taken as granted that the topic is about laser-ablation or laser-impulse propulsion.

I do agree that if someone starts to go on a tangent about another form, he should be corrected. Unless the comment contributes to the topic at hand of course.

>>5930208
No. The c problem is not one of mass but of inertia. And negative mass still has normal inertia.

And the c problem is not even that simple, there are other fundamental laws which prevent it.

>implying they're not in the rimjobbing brown-nose tier
Business law is in the sub-category of pig-rimjobbing brown-nose tier.

>>5930160
How is that a problem?
Those seem like different methods for different applications, which is natural.

The alignment problem could be mitigated with an actively homing laser.
And if laser sails are used in the inner system, we could go the oft-imagined Asimov-Array route and put the power collectors and lasers on Mercury.

Utilizing the Mercury lasers, we could then send fuel, propellant and other volatiles(gleaned from comets entering the inner system) to depots in the outer system for use in nuclear-powered craft and to power whatever bases and outposts that might be established there.

>>5930135
No, you can't reach speed of light even with a negative mass. You can approach it asymptotically, but you're still in the inertial reference frame of the universe and bound by the speed limit.

>>5930123
No, antimatter gravitates normally.

What you would need is negative mass, which is a different kind of thing altogether.

>motion of the planets
Totally fucking lost it.

I mean seriously, I not only woke up the whole house, but three of my neighbors too.

This shit is fucking comedy gold.

Sure, I'll have to sleep in the hotel for the rest of the night, but this is so funny that I have no regrets. Thank you OP, this is the funniest stuff I've read all year.

>>5929961
Not that guy, but you can still get a lot of momentum from the laser while the rocket is still atmosphere. End even outside atmosphere, the rocket could carry a little propellant to be injected into the reflective cavity to be heated by the groundside laser.

Even if these methods couldn't provide the boost to get the rocket into orbit, they could increase launch efficiency.

>>5929989
No.

>>5929974
Actually, if you attach a mass and a negative mass to your ship, the negative mass will fall towards the mass, which will be repelled by the negative mass, providing acceleration.

Now, whether negative mass is possible, and even more whether it's possible in a compact form, that's the question. And the answer is probably 'no'.

>>5929960
Not that guy, but no. You also need either a large mass or a large negative mass.

But you could use the antimatter to heat up some propellant and thus attain high relativistic velocities.
