For ex. in a video-interview with John Conway, he said if there is one question he'd like to have answered until he dies, then it's why the monster group even exists. Which means at least partially they're discoveries. But to discover something you first need to invent the proper tools to get there.

>>8284578
Actually OR as logical operator allows both, your argument is invalid.

Oh jeez another pop sci fag
All you need to know is that magnets wear down over time

I didn't understand, did you say that is true, or it isnt?

>Is this true?

Not at all.

Most of the videos that have "working" versions of these are hoaxes that use an airflow off camera to spin the "motor".

The main reason for these not working is due to the "cogging" effect between one magnet field and the next. This robs power from the spin even if you manually spin it to get it started. The more magnets you add the more "cogs" there are, the smoother it will be, but it reduces the pushing force and still robs it of power. One of these without "cogs" and a full field is just a magnetic bearing. All of these are just magnetic bearings of varying efficiency. You must input the energy into them for them to work.

Even that has nothing to do with this.

Myers briggs was made up by people with no scientific background.

Neither Isabel Briggs Myers nor Katherine Briggs had any formal psychological training.

Even renowned psychological theorist Carl Jung, whose writing formed the initial inspiration for the Myers-Briggs test, admitted that terms such as “introvert” and “extrovert” were false dichotomies and entirely too limited to either adequately describe or predict human behavior.

Up to half of the people who take the test a second time end up with a different personality classification, even if they take it within five weeks of the first test, just like a fucking horoscope.

According Annie Murphy Paul’s The Cult of Personality Testing, “as many as three-quarters of test takers achieve a different personality type when tested again…and the sixteen distinctive types described by the Myers-Briggs have no scientific basis whatsoever.”

Multiple studies have clearly demonstrated that the MBTI is incapable of accurately predicting job performance.

The test is used by most Fortune 500 corporations, but it is not typically used by professional psychologists.

Stanford University psychology professor Carl Thoreson, who is on the board of the company that issues the MBTI, has never mentioned the test in the over 150 academic papers he’s published. “I didn’t use it in any of my research,” Thoreson says, “in part because it would be questioned by my academic colleagues.”

The National Academy of Arts and Sciences conducted a study that concluded that the S-N and T-F scales had little to no validity.

There is absolutely no scientific basis for the test’s terminology, which has been criticized as “vague and general.”

Need i go on? It's pseudoscience that tells us what we want to hear. Just like most science fiction.

and in case you don't know about the MBTI personality type, I would strongly recommend that you try it out: https://www.16personalities.com/free-personality-test

You get comprehensively BTFO every time you make one of these threads. A regular person would have reevaluate what they knew, or what they thought they knew, and perhaps gone away. But not you, it's almost impressive.

There aren't many people that think black holes are the source of dark matter.

In order for there to be no dark matter, our field equations would need to be revised. Please post your argument in these terms. If you don't explain how, your explanation is worthless.

>>8284393

Our black hole model is wrong, world lines do not cross over event horizons.
Spacetime below the event horizon is inverted. The singularities of the event horizon and at the origin emerge because the black hole is built upon a spherical metric which becomes inverted and an inverted sphere is a pseudosphere which has a singularity at its equator and one at its origin.
The negative, inverted spacetime of the black hole can entangle a distant black hole, forming an Einstein-Rosen bridges.
The E-R bridges form galactic strings which curve spacetime in our positively curved universe resulting in the so called "Dark Matter" phenomenon.

Dont want to think about it, it's a horrible act, a person lives and grows for so many years, thinks, feels, creates, experiences things and it's taken away in such a horrible way. It's fucking barbaric, I just hope it's not painful it really is horrible.

Because people are allowed to publish things you disagree with.

>>8284100

Post a tl;dr version of the paper, OP.

>>8284106
the abstract is right there, in bold

Not sure either. Maybe apply residue theorem if w is inside C?

>>8284104
This, they want you to consider the two cases of w inside C or w outside C

something something quantum states I guess.

Sub atomic particles. Electrons maybe, quarks have a better chance.

Dark matter sounds plausible, but I'm not redpilled enough to say for sure.


By the way, how big is a zero? That pic is retarded unless it tells me how large each zero is.

It would fit in the universe though

Since the universe is actually 10^1220 bigger than the "known universe" (aka what we can see at this arbitrary moment in time because it has been able to travel the distance at light speed given enough time and taking into account the expansion of the universe)

>>8284040
derivative if the slope of the graph

derivative of units is rate of change with respect to something

integral is the area under the graph if you cut it into infinitely small pieces

integral of f(x,y)dy = f(x) + C

>>8284043
The last one is wrong. Integral of f(x,y)dy = F(y) + c(x).

we used to be hetero sapians

then we thought fuck girls and became homo sapians

The changes in morphology over time reflecting shifting lifestyles as species transition is interesting, as well as the uncovering of fire, developments and refinements in tool styles, the creation of art and music without precursors.

Not to mention rapidly expanding species distribution to all but Antarctica prior to the development of agriculture.

Probably because a lot of higher (or even middle level) mathematics is almost pointless to their lives, so they have no reason to learn it

What practical value is there for the common person

guilty as charged. Now I need to learn math in order to pass this fucking certification test. I've taken a few practice exams and tanked all of them, like a 50%.

I'm truly fucked. This test is a requirement in almost every state, and in every last state worth teaching in. If i can't do this I might as well have not bothered wih the last few years of my life.
