Why would magnetic monoples exist? Isn't magnetism just relitivistic electricity?
>>
I'm a physicist (second rate, admittedly), and I completely agree.
>>
the relativistic model is just a way to explain what is happening as far as we know. That doesn't mean that it's actual how nature operates or everything there is. It works because magnetic monopoles haven't been detected. But if new evidence is added, then we need to modify the theory, or get a new one.

You need to get it through your head that physics theories become theories when they can predict and model what we currently know about nature accurately. That doesn't mean that's all there is or that there aren't other acceptable theories.
>>
>>8394543
If monopoles did exist than how would out understanding of the universe change? Would other forces develop magnetic monopoles as well?

If we were to point our telescopes somewhere in the universe and see the light that bounced off of earth hundreds or thousands of years ago could we see into the past?
>>
>>8394506
What do you mean "see" the light that bounced off of the earth? To do that, Wed have to PUT our telescopes thousands of lightyears away from earth then then point them TO earth
e.g. to see a dinosaur you can go 60 million light years away (instantaneously), point your telescope at earth, and you will see dinosaurs.
To see before the time you leave the earth, you must travel at the speed of light or faster to your viewing destination
>>
>>8394506
SEE THE LIGHT THAT BOUNCED OFF OF EARTH HUNDREDS OR THOUSANDS OF YEARS AGO
SEE THE LIGHT
BOUNCED OFF OF EARTH
SEE
BOUNCED OFF
pure retardism, you can't see something that's bounced of off earth because the travel distance of light from the bounced from the earth is greater than the speed of light is after it bounced off. You can only see the past earth if the super telescope is pointed towards the earth between 10,000 to 10 light years away from the earth. I dunno what people in /sci/ are but...
>>
>>8394585
Like if it bounced off of something else.

For example the light bounces of earth then it bounces of off something mirror-like somewhere in space then comes back towards earths path many years later.

If some sort of advanced telescope could be pointed at this mirror like object could you see earth thousands (probably millions really) of years ago?

Some people claim that it was an evolutionary trait to attract women, but I feel like men's humor is probably more of a benefit to keeping the male members of a tribe together.

As we know, in DNA Replication the Helicase (which I believe is an enzyme) separates the double-helix of the DNA strand, and from there a complementary copy of the gene is created as mRNA.
Feel free to correct me if I'm wrong, or elaborate further.
In RNA Replication, there are two processes, Transcription and Translation.
In both there are three steps, Translation happening after the former, Initiation, Elongation, and Termination.
In Initiation, the RNA Polymerase binds to the Promoter, just under the TATA Cap.

Ah, yea, thank you.
The Polyadenyl is just that long strand of A's at the end to keep the RNA from degrading iirc.

I apologize for the lame question as well, but what exactly are Introns?
Are they just unneeded pieces of code, and are therefore spliced out, or is it something else?
>>
>>8393953
they are unneeded, or they contain skipped exons, or they serve as a mutation pool, or they have regulatory sequences/secondary structures. it all depends.

Thought I would offer up a new toy for you guys to play with: apply the Grothendieck construction to the functor from sets to categories obtained by composing a contravariant hom 2-functor (for some fixed category C) with the functor taking sets to their corresponding discrete categories. Objects in the entire category for the induced bundle are like sets, but rather than bags of structureless points, they are bags of objects living in C. A morphism is a function on the underlying set, but where each assignment f(x)=y is actually a morphism x—>y from C. Notice that we can...

So this fucking CS autist walked by me today muttering something about the singularity. Some engineer probably stole his trash gf. He then started stuttering about how he's going to create a program that will do the job of engineers. Just laughed in his sad face as I waved my professional engineering licence at him. Why can't CS majors admit to themselves that they are nothing more than codemonkey servants who will never be considered real engineers? Even more sad is how they actually believe the baby set theory and combinatorics they studied puts them on the same level as mathematicians. "HURR muh Hamming code thus I know abstract algebra." Not that they even use any of that math to write their fizzbuzz scripts which is literally the only requirement you ever need to get a CS job. Seriously, they don't even know how to build the computers they use. Electrical and Chemical Engineers had to solve integrated circuit production because they too busy jerking off and playing tabletop Doom. They couldn't even develop their own abstract architecture which is why Von Neumann -another ChemE and mathematician- had to step up. Do we even fucking need CS majors when there are a million poo in loos that write the same crappy HTML bloat we hire them for? Furthermore it's the most beta profession and it's a proven fact that literally every CS major is a closet /mlp/ horsefucker. That's why they are too stupid to ever crack hard AI and we need to put mathematical researchers on it asap. Not that we could've expected much from them since they are busy jacking it to horse cartoons to even bother learning REAL control engineering and neural network optimization. I guess life is great when you can spam ML models like a monkey instead of THINKING because engineers built them computers too powerful for them to care enough to DO THEIR FUCKING JOBS RIGHT.
