industries that sell decent healthy products aren't driven to engage in that kind of bribery and fraudulent advertising because their products already speak for themselves. thats why you should never ever trust a scientist when they're trying to tell you what to eat or what else is good for you. they're only telling you that because they're being paid to and they have no consciences about lying so they don't mind shilling poison, they can rationalize any kind of lying in order to get money because they are that greedy

It's just like every other applied math discipline (e.g., Engineering, Computer Science, Physics).

There's differing levels of mathematical development needed for different sub-fields. If you are getting into mathematical statistics, you will likely end up doing a pretty thorough course in measure, functional analysis, and algebraic geometry/smooth manifold topology. I'd call this pretty close to mathematics.

If you are doing more "application" oriented work, you probably won't need much of the real sophistication required for more general approaches to statistics. It all just depends on what level of depth you want to pursue statistics.

Female ferrets, once they're mature enough to breed, will become extremely ornery and violent if they aren't bred. If they go on long enough without being inseminated, eventually the estrogen buildup in their bodies becomes so severe that it will kill them, they become lethargic once its really bad and then die of anemia. So inability to breed is a death sentence for a female ferret. I doubt this is unique to ferrets, but I haven't studied the issue.
It seem likely, judging from their behavior, that human females go through something similar, although not severe to the point of death. Inability to breed seems to turn women into massive bitches and I get the impression that birth control pills mitigate that kind of hormonal activity.
So my theory is that if you know a girl who is a massive bitch and she isn't on bitch control of getting fucked regularly then thats probably because she wants to be inseminated, craves it desperately.
Is there any actual scientific research thats covered this topic?
I don't know much about it outside of my familiarity with ferrets and my experiences with women.

One thing is for sure, it isn't like that because ecotards are trying to make the world a better place.

Bad news fellow vaxxies, the "turbo cancer" rumor that the conspiracy theorists have been yammering about has turned out to be completely true, as proved by this recent publication:
https://pubmed.ncbi.nlm.nih.gov/38234925/
>The "hallmarks of cancer" were proposed by Hanahan and Weinberg (2000) as a group of biological competencies that human cells attain as they progress from normalcy to neoplastic transformation. These competencies include self-sufficiency in proliferative signaling, insensitivity to growth-suppressive signals and immune surveillance, the ability to evade cell death, enabling replicative immortality, reprogramming energy metabolism, inducing angiogenesis, and activating tissue invasion and metastasis. Underlying these competencies are genome instability, which expedites their acquisition, and inflammation, which fosters their function(s). Additionally, cancer exhibits another dimension of complexity: a heterogeneous repertoire of infiltrating and resident host cells, secreted factors, and extracellular matrix, known as the tumor microenvironment, that through a dynamic and reciprocal relationship with cancer cells supports immortality, local invasion, and metastatic dissemination.

Cherry blossoms bloom in Tokyo, 15 days later than last year, 5 days later than average

https://www.japantimes.co.jp/news/2024/03/29/japan/society/cherry-blossoms-bloom-tokyo/

Cherry blossoms finally burst into bloom in Tokyo on Friday after heavy rain in the morning, marking the latest blooming in over a decade.
The declaration of the blooming made by the Meteorological Agency came 15 days later than last year and five days later than in an average year. Private forecasters had also expected this year's bloom to come much earlier.

Friday’s blooming is the latest in Tokyo since 2012, when cherry blossoms were declared to have blossomed on March 31, according to the agency.

Cherry blossom forecasting is big business in Japan. As early as in January, companies start to issue forecasts for when cherry blossoms will first bloom and reach their peak.

The weather agency, which began forecasting the annual bloom in 1955, sets a government standard for observing cherry blossom trees. For consistency, the meteorological agency only uses data gathered from the Somei-Yoshino variety, which produces pale pink blossoms.

But all the money is in business. In fact, if you suck corporate dick you can make millions as a scientist. History is replete with scientists who sold their souls to corporations from Thomas Midgley Jr who lied about the dangers of leaded gasoline to all the researchers who lied about cigarettes for decades.

You dumbfucks have to twist yourselves into absolute knots in order to not only ignore the mountains of evidence about climate science but to conjure up the most ludicrous conspiracies imaginable just to suck oil company dick. Oil companies who know the science is against them so badly, they now openly admit it

>As Shermer observed, many science journalists see their role not as neutral reporters but as advocates for noble causes. This is especially true in reporting about the climate. Many publications now have reporters on a permanent “climate beat,” and several nonprofit organizations offer grants to help fund climate coverage. Climate science is an important field, worthy of thoughtful, balanced coverage. Unfortunately, too many climate reporters seem especially prone to common fallacies, including base-rate neglect, and to hyping tenuous data.

I think the way that the concepts of relativity are taught fundamentally leaves people with an incomplete and incorrect understanding of the nature of space.

People are taught that our universe has a set speed limit called the speed of light and that nothing can go the speed of light because it just takes too much energy as you get closer and closer to that speed. But the way this is described is quite misleading. My little object can go as fast as I can accelerate it to, there isn't some speed limit to the object itself (well there are some factors that might limit my speed but they don't operate on the same principles as the magical speed limit people think the speed of light is). My object can go as fast as it wants, faster and faster as it approaches infinity (relative to a stationary observer of course). The thing is, someone standing still relative to my object, will never see it go past the speed of c, they will observe it being limited, slower and slower, and closer to c as its "true" speed gets faster and faster.

This is why I hate the term "speed of light", it births all of those misunderstandings of what that speed really means, like when people ask "If I'm on a train going at 99.999999999% the speed of light won't the light come out really slow?", of course it won't because that light is traveling away from you infinitely fast, and as an object with mass you cannot have infinite speed, you will never be able to keep up with that light, it's fundamentally in a different realm of existence from you.

These concepts shouldn't be hard to understand, but it is hammered into us from a young age how "light travels at the speed of light and you can't", and "the earth is moving at 30km/s" with frequent disregard for reference frames. It's no wonder many people find relativity so hard to understand, you might as well try to teach someone their second language at age 80. Don't you think the way we teach people should be changed?

Basic spacetime trigonometry needs more attention. Light has finite speed but infinite rapidity.
>>
The more intuitive way to think about it is that *everything* moves through spacetime at the speed of light. It's simply a question of how quickly it's moving through the "space" part of spacetime versus how quickly it's moving through the "time" part of spacetime (as perceived by observers in other reference frames).

Light in a vacuum is travelling at c, but it's travelling at c exclusively in the "space" direction.
An object stationary relative to you is travelling at c, but it's travelling at c exclusively in the "time" direction relative to you.
Anything in between trades off motion through space relative to you for motion through time relative to you.
Changing an object's inertia through spacetime requires applying impulse/doing work to change how much of its motion is through "space" versus "time", but it's always going to be moving through spacetime at c. You can't accelerate something to any speed you want, because you're inherently limited to that upper limit of moving at c completely in the "space" direction.
>>
>>16172858
>Light in a vacuum is travelling at c, but it's travelling at c exclusively in the "space" direction.
This is plainly false. If light traveled exclusively in the space direction (relative to me), it would reach its destination with no time delay. Don't try to "explain" it to me; you are wrong.
>>
>>16172844
Sure I can't move faster than light can from your point of reference that's true. And I won't be able to move faster than light from my perspective either. But I COULD theoretically go faster than 299,792,458 m/s from my own perspective.
>>
>>16172858
You're partly right, but you've made a pretty significant error - as >>16172866 said, light does not travel exclusively in space. Rather, light follows 'null' trajectories in spacetime: Experiencing neither a change in proper time or proper space, and travelling with a unity slope in any coordinate spacetime frame.
