I think you just defeated yourself with your own argument

>the same way horse carriages are not any more useful or complimentary to internal combustion engines.

In the simplest terms we have combustion engines because someone wanted to make something that worked better than a horse.

It takes power/energy to move trade goods across land. at one point horses were that energy source to move product. Think about how people moved large amounts of goods before the industrial revolution. We used horses tied to carriages. One of the most defining moments that caused such a roar from the industrial revolution was the fact someone designed a steam engine that out performed a horse. One person saw a horse, and saw soft flesh, brittle bones, with a short shelf life. He took that vision and turned the old power source (a horse) to steel and fire. horse carriages led to engines the same way the wheel has led us to all the technology in the world. In time philosophy has led us to pursue a thirst of knowledge that will not be quenched until mankind either learns everything about everything, or we wipe ourselves off the face of this plane of existence.

Some nutjob philosopher has come up with the idea there are an infinite number of universes thinking of our existence. eventually we will realize whether this is true or not by developing the technology to rip doors into other dimensions or finding the end of the universe, seeing if the infinite number of impossibilities we couldn't begin to imagine. Science progresses with ideas, philosophy gives birth to those ideas, and should be a strong guide to whether or not those ideas should be pursued.

One of the biggest questions of philosophy is "what does it mean to be a good person?" Forget all the ethics bullshit and ask yourself. I hope most people on the board answer in some shape of "to better mankind with new knowledge and improve our mantle in the world as its caretakers" to some people that means pushing renewable energy and off fossil fuels so we could are no longer teraforming the planet to kill us. Others it would be trying to figure out how to feed the world so ==insert accurate statistic== here of the worlds population isn't starving, and the other ==insert accurate statistic== aren't obese fucks gorging on the plastic never decaying food of mcdonaldPost too long.

Where?

I disagree with putting philosophy on chan, because it's full of teenage retards and subhumans. Science is different from philosophy, they are not seeking the same thing, stop being retarded

>>1324
Really because i wrote a paper specifically about how the theory of relativity was heavily influenced by writings from hume and some other philosopher.

Philosophy of science is a real discipline and an important one if you want to make real scientific progress as opposed to just practicing normal science.

>>385
Technically science is a branch of philosophy (that may be the wrong term for it). However, I think with that in mind philosophical discussion should be kept to a more relevant board. Philosophy as it applies to science ought to be fine though.

I think it's a fair point to bring up that no one on this planet is going to know what the center of our galaxy. Our understanding of physics is primitive and the equations used to try to understand will produce a wide variety of results. for all we know every theory we have is right, or all of them could be wrong, and a giant glowing set of testicles is what our entire galaxy revolves around. Our laws of physics and matter could be null and void in another solar system, or even on a different planet in ours.

>>1197
how accurate is anything we have about the universe outside our little blue ball?

>>1357
How accurate the shows are

Is it all reddit-tier or is it actual science explained well

>>1197
They tend to gloss over basics and not go into intense details. It depends on whose producing it really. PBS/NOVA tends to be reputable, and BBC actually does some pretty good documentaries (even if BBC does a shit job at everything else)

>>1416

It's bullshit

>>1416
No. The microwave photons collide with molecules and become kinetic energy (just heat)

IMO the text OP is reading sounds like it was written by some non-science fucktards who think:

>"lol radiation is just like evil and stuff because [insert tinfoil shit here]"

>>1416
bullshit

We don't know yet how the universe was formed. When we know how, it would frankly be weird if we couldn't replicate the situation and generate a new universe for ourselves, with blackjack and hookers.

The dominant hypothesis - inflation - actually violates conservation of energy (because the conservation law is only true in non-changing spacetimes). There is no obvious violation of any law of physics for allowing people to harvest that energy forever.

>>1412
This.
Wasn't there a time when physicists thought everything to discover had already been discovered and the only thing left to do was "fill in the last decimal place"

Then out of nowhere comes all sorts of crazy shit like relativity and QM.
People will always be naive enough to think they understand the full picture

Think of the bright side…
Nobody will know you played all those nasty Nipponese games.
Nobody will know your Internet History.

>>1417
My internet history isn't embarrassing, though? I only go shopping or use 8chan.

>>1406
Now we wait for their lander to be blown off the comet by a jet or never wake up

It looks gross..

It's like it rolled in shit and got forest funk stuck to it.

>>1379
Well, okay.

But still, breaking your own toe bones for self defense is… just fucked up.

>>1374
Erm, I mean, each reflects itself vertically across the horizontal midline.

>>1374
So how about that first column from the left?

>>1382
I'm not seeing any pattern within the columns that doesn't require a lot more rules, and I think I've seen IQ test questions like these before and am fairly certain the examples are arranged in rows.

>>1130
A-a recreational math board?
Well golly gee, count me in.

>>1130

I like puzzles.

Too hard for me.

At what point does Math turn into a Puzzle?

And vice versa?

>>1130

Do we need a separate board for this? I think it would feel right at home as a general on /sci/.

I have to leave. I'll be checking back on this thread occasionally.

they are the easiest to test for primality compared to numbers of the same size

marsenne primes are not necessarely better than normal primes, the formula is only a way of finding new primes easily. As far as we know, marsenne primes are the easiest way to find new prime numbers. To find out more about them, google "marsenne prime research" to find the GIMPS webpage.

>>1349
>>1348
Thanks

But who cares about finding large primes?

>>1350
Large primes are very important for lots of cryptography stuff.

>>1351
But beware that large is very subjective. The largest known primes are far larger than the ones used for cryptography.

>>1330
I think it is more likely all the lighter hydrogen just got sucked of the earth and absorbed by the sun. Which is why earth has such a high proportion of heavy elements, and the sun contained 99.8% of the mass in the solar system and is almost completely hydrogen and helium.

If I had to guess I would say second generation, with possibly some acquired residue frpm somewhere else.

bump

it's a trick question. Judging by the graph he is measuring an led. I guess he calls it led bulb. i think that is what he wants you to realize is this is a diode.

>>1268

8chan died while I wrote you a reply.

Don't remember it.

What do you mean by "in front"? (Your image says the plane is stationary so I'm reading this as you're rotating about a point)

>>1268

You would need to know how fast the blue airplane is going. Assuming that blue plane's speed does not change during the maneuver, the trajectory makes an arc. If I'm not mistaken, the "turn rate" is merely the rotational velocity along this trajectory, so we can apply ω=v/r where v is the speed of the blue plane and r is 5000m.

I think the red airplane's speed would be a red herring here because you're just trying to find the rate at which you'd have to turn the blue plane to make it face east/west along that line.

>>1258

Yeah it sounded a bit brute force when I read it back to myself.

Don't forget to actually think about what you're doing and don't be afraid to play with what you have learned outside of what is shown in the examples.

>>1259
this is not methodological at all but i've found some of my best learning sessions to involve trying to prove/test the limits of an idea or do some dumb project. like for imaginary numbers i did a unit circle with the coordinates for main angles (0,45,90…) in imaginary coordinates

Studying algorithms on KA at the moment. So far I'm really enjoying it.

>>1241
This does bug me a bit about KA. It had better assessment tools so you can skip all that primary stuff. It takes a lot of time.

As for text books I highly recommend Introduction to Algebra from the Art of Problem solving series. It includes really tough questions and word problems beyond the redundant 'solve for x' type activities.
