idk

It's a consequence of special relativity, and the dynamics of the fields that are defined in a Lorentz spacetime.

philosophy is not necessarily important, but like pure math, it's fun.

the same argument can be constructed by replacing the word "word" with "number" and the word "philosophy" with "mathematics"

do you also judge mathematicians?
how about a similar argument against physicists?

or maybe i should remember you're either in highschool or a first semester undergrad and disregard your post entirely

>>8313360
mathematicians don't question axioms

>>8318194
yeah, but its gonna be a bunch of little dumb robots and not some anthropomorphic robo-butler.

>>8318194
god yes i hope so

would love to see these goyim struggle because a robot is doing their job better and cheaper

>>8318194
I hope robots don't kill us or replace us.

>>8314780
r u an undergrad?

>>8314781
Nope, I work in industry. Finished my PhD in 2011. Not a super long career by any means but willing to share my insight if anyone is interested.

is there gonna be eternal life in these 50 years?

What makes you think there has to be a purpose for it ?

>>8313702
Because evolutionary process rarely allows unnecessary, wasteful traits to propagate? Surely creating this illusion must take precious neural "computing" space and take energy which could be used for better purposes if it was unnecessary. Why it even evolved in first place?

We are territorial and tribal in nature. When we unite in smaller groups, we dedicate ourselves to them and the isolation from the rest becomes inevitable.

To unite the world, you need a common enemy. If there was an alien attack threatening mankind, we would feel the need to unite all together and our banner would become one.

Because there isn't just one species of human and the interspecies' relationships are not good now and never have been. Currently things are only getting worse.

From this picture it is clear that the reason for the rocket's demise was due to a flaw in the construction of the launch pad, not due to the rocket itself. Whoever assembled that flawed launch station is to blame. Bot the people eho designed the rocket.

In my first sentence I meant to say the pink function.

I see, so it's funny to pretend to be a retard and say that everything and everyone is a meme.

No.

Some say he was the next step in human evolution.

I think he was secretly a x-man

Would you suck his dick?

just because.

Do you debate Newton's laws in physics 101?

I think you lost on your way to /pol/. This is /sci/ -- The science board.

Are you expecting a physics professor debate whether gravity is real? No, and it has nothing to do about political ideologies. It's just stupid and a time waste to debate about topics that have already been proven correct.

Let's debate evolution in Evolutionary Biology

Let's debate the Fermat Theorem in Mathematics

Let's debate Gravity in Physics

Let's debate Astrology in Astrophysics

Because the Space Shuttle was more complicated device than the Saturn-V and the new SLS. Which means more failures (Challenger and Columbia).

Likewise, the STS's max payload was 30 tons while the Saturn-V's was 53 (the new Falcon Heavy's is also 53). SLS Block I will be 70 tons, and SLS Block II will be 130. Despite all the cynicism /sci/ has for NASA, SLS will be a huge step forward for space exploration as it will allow NASA to start putting big things in space again. In particular, a bigger and better ISS and parts to moon bases.

>>8309788
>exploration
implying spacex wont cuck them all


the falcon is about to be reusable that will be a giant space revolution of changes

like, that is like if nasa were a little dime on the ocean and spacex were a giant planet billions of light years across

because the space shuttle was a fucking retarded design

SLS is also a retarded design though

theoretical """"physicists"""" on suicide watch

>>8310428
Nope.
Also terraforming is a fantasy. Fuck off.

>>>/x/

Wew, theoretical physics is in a right state. The desperation for new ideas has led them to completely abandon reason.

Are these good quality files?

You're science majors not ebook-collecting majors. Don't pretend you're gonna read it in your room. Go to the library, open the book, do the exercises.

Probably, if you use it too often. The benefits generally outweigh the risks, however.

These are risk factors for ionizing radiation-producing medical imaging to cause cancer

>being a female(almost doubles your risk)
>being a child under 5 years old(you're growing very rapidly and the room for error is large and typically fatal)
>having a genetic predisposition like Neurofibromatosis(fairly rare and you would know if you had it based on how many of your family members had incidents of cancer at a-typical ages)
>having several or more of the same scan in a short period of time(two scans at a time, non-contrast/contrast each week for several months, etc)
>being scanned on an older machine or one that has not been calibrated and gives you a dose much higher than the average(DLP that is above the 75th percentile for that particular scan) repeatedly
>scanning organs that are more susceptible to radiation damage(anything in the torso)

From everything we know, the doses you receive from Plain Film x-rays, CT scans, Fluoroscopy, Nuclear Medicine, and Interventional Procedures are simply not enough to induce cancer in any statistically obvious way. If such a reality exists, it is rare and will occur due to you fitting one or more of the above risk factors.

CT scans are the funny ones because everyone freaks out about them. CT scans are simply images taken at typically 5-7mm apart, so it's not the same thing as being in a nuclear incident. It's like getting a normal x-ray, but you get one for every 5-7mm of whatever you're scanning. The actual dose isn't what your getting to all areas, but split between all of the images, so it in reality is no different from a plain-film x-ray in terms of dosage.

>>8296980
We had a huge thread already.

The answer is obviously and definitively NO.
You can start scaremongering again about how a couple CTs a year can cause cancer but everyone knows you're just pretending to be retarded.
