How to lay out a personal research schedule in mathematics?
By "personal" I mean not necessarily tied to reports to "authorities".

Do you always usually fragment the work into chunks, with dates where you want to produce what sort of result, and do you schedule literature time?

If you ever read any formal texts, topics always culminate in a 'master equation,' with the prior equations in the topic being inculcated into this equation. Memorize it, and be able to use it for every topic it applies to. The 'integration' half of the text will have you using these equatiins in tandem or on subjects that might surprise you in how they fit.

From someone who almost exclusively self-studies: don't schedule anything. Just set aside as much time as you are willing to invest each day, and start reading stuff that piques your interest. The second your interest has fled, you ought to start learning another math thing (perhaps related to the last). Keep following your sincere curiousity, and everything else will fall into place.

Also, keep a notebook to scribble down your own ideas. Anybody can do math research, and you will mature in extraordinary...

Hello!

I'm currently collecting penile measurement studies on blacks.

I'm only interested in real measurement studies, self-reported data is not reliable enough.

I have a hypothesis about jupiter's spot.

Now, as we know, jupiter's surface is covered in gaseous hydrogen; and we suspect that deeper down it will be liquid metallic hydrogen.
Is it possible that a meteor struck the atmosphere of jupiter at a steep angle - slicing through the hydrogen layer and popping out of the other flank of the planet, leaving behind a large spot that has taken millennia to refill.

Just imagine, for decades Jupiter would have had a hole running right through its side. It's a shame that we didn't have the opportunity...

would make sense with the smaller spot on the right as an entry wound and the larger spot as an exit...

Probably not.

Comets constantly crash into Jupiter, and by "crash" I mean they break into literal bits due to Jupiter's force.

You are underestimating the size and power of the planet.

Wasn't it confirmed that it's a huge hurricane anyway?
>>
That's an interesting theory. Maybe it was made by a big ass asteroid (dinosaur extinction level) going too fast to break up and hit extremely hard, and the hole left from the impact caused gas to pour in, starting a storm, and it spread from there.

Also, nice post number!

Ain't quantum mechanics just a probabilistic model of estimating things we can't actually see and this "existing in two places at once" is just a miscomprehension of said model. How wrong am I?
14 replies and 2 images submitted. Click here to view.

>>8184661
Very wrong. If it were simply a probabilistic model, experiments such as the quantum eraser experiment would yield more "intuitive" results than they do.
>>
>>8184661
That was the original interpretation, but then things like Bell's inequality ruled out hidden variables (at least local ones).

Biggest difficulty with quantum mechanics is interpreting what the mathematical framework means in a physical sense. And that's something that's still not agreed on to this day.

It's plausible that in the subatomic world non-locality can emerge.

Hello,

I'm planning to start university this year and I would like to get some input on picking the right course for me. Only thing I know for sure is that I'll be going into the STEM field because that's what interests me the most and I'm very good at. So far my favorite choice is Physics because I feel like it's a broad field allowing me to go a lot of different directions later on, it's very theoretical so it'll hopefully shape my thought process and problem solving skills but with some practical applications unlike studying mathematics...

Geology lets you go to cool and interesting places.

Civil Engineering can be very complementary if you focus on economic geology.

You have some control about what you're researching, pick something interesting. Go to fantastic places with that kind of interesting stuff. Curse yourself every morning as you wake up and drink a cup of shitty coffee and walk around the mountains with no cell services for a few week.It's fun.

Logarithms I bet.
Because log(3n + 1) = log(3) + log(n + 1/3).
And also log(n/2) = log(n) - log(1/2)
Therefore, logarithms.

What's making them bigger? Isn't their bones getting larger, thus they wouldn't be small in proportion to the person.

Ordinary human growth. We can't make a skyscraper the height of a space elevator out of steel and concrete because the length would exceed the specific strength of the beams. The same logic holds true for a skeleton on a giant person.

I think the limit of the heart to pump blood to the brain would be reached before the limits of bones and cartilage.
