>Abstract
>Researchers have demonstrated relationships between dark personality traits (e.g., narcissism) and pandemic behaviours (e.g., disregard for public health interventions). Individuals who disregard public health measures risk spreading COVID-19 infection, which has important public health implications. The present study was designed to examine the relationship between narcissism and pandemic attitudes and behaviours using a large population representative sample of North American adults (N = 5812). Participants completed measures of narcissism, psychological entitlement, non-adherence to non-pharmaceutical public health interventions (NPI), COVID disregard, anti-vaccination attitudes, reasons for social distancing, and COVID stress. Results of MANOVA demonstrated that individuals with high levels of narcissism self-reported greater levels of non-adherence to NPI, COVID disregard, COVID stress, anti-vaccination attitudes, and psychological entitlement compared to those with low levels of narcissism. Further, men with high levels of narcissism self-reported greater levels of non-adherence to NPI, COVID disregard, COVID stress, and psychological entitlement, in comparison to women with high levels of narcissism. These findings provide a nuanced understanding of the relationship between narcissistic traits, sex, and pandemic attitudes and behaviours and have implications for tailoring pandemic-specific public health interventions based on individual difference variables.

Universe is really, really young from cosmological perspective and we are really, really early to the party.
>but universe is billions of years old
First stars needed to burn up to fuse heavier elements than hydrogen and helium
You can't do any complex molecules with those so you need to wait tens of billions of years before life can start to form
You need Sun-like stars to happen. You need loads of carbon and metals around.

The oldest Sun-like star is less than 4 billion years older than the Sun.
Forming the simplest life took 1 billion years, eukaryotic cells roughly another billion, multicellular life took another and forming higher life took another billion
so one can assume each major evolutionary step is 1 in a billion years sort of occurrence
Life (probably) needs to survive at least 4 billion years unhindered before it evolves to a form that can send out spaceships and stuff and we had several near extinction events ourselves. Even a single total extinction event would entirely nullify the head start other lifeforms might have had on us on some point.

Meanwhile, the estimated universe lifespan is about 100 trillion years
In other words:
If universe was a party that starts at 18:00 and ends at 2:00 the next day, we showed up not even 2.5 seconds after the club opened up and we are wondering where all the liqured-up babes are.

I think you are literally the only one just like I'm the only quantfag I've ever seen. Well there's that finance guy who I guess counts. Unless there are multiple microbiofags who keep asking where the other ones are and never meeting lol

Describe red to me in a way that will allow me to see it the way you see it. I am blind. That's what I thought.

The notation P(A|B) means the probability of A happening if we know that B happened; in other words, A conditioned on B.
Assuming B has nonzero probability, we define this as [math]P(A|B) = \frac{P(A\text{ and } B)}{P(B)}[/math]. For example, P(Y = 0 | Y ≥ 1) = 0 in your problem.

>>14508023
Yes. Generally, if B and C are two bases of the same space, there is always a linear transformation taking one to the other -- the very definition of B being a basis means that C can be written as a linear transformation of B's vectors, and this transformation X must be invertible for C to be a basis.
Then, you can "lift" this transformation up to the full M-space by setting the orthogonal complement of ker(M) to not be changed by X, which makes sure it's still invertible.

If the current source is DC, then a capacitor acts like a break in the circuit -- no DC current can travel through an ideal capacitor. A capacitor only conducts when the voltage varies.

Or maybe it's because of shitposters on this very board.

I don't understand why so many /sci posters are so obsessed with their profile. I feel like it comes from a feeling of insecurity in your intelligence, so you think your facial profile somehow equates to being less of a brainlet.

Do you think people actually out there accomplishing great things give a shit about something as mundane as a head profile?

Jesus man, fuck off

Eddison was a full blown impostor.

The guy could barely count to 10. His patent trolling is vastly understated, he never even came close to invent anything on his own but the high level American academia, government and industry rewrote history to attribute anything that couldn't be easily traced back to someone else, to him.

The axiom of choice is obviously right, the well-ordering principle is obviously wrong, and as for Zorn's Lemma, who knows?

If I was smart enough to definitively answer that question I wouldn't be dumb enough to waste my time on /sci/.

The kardeshev scale isn't exactly scientific. It's just some very broad strokes interpretation of possible levels of the evolution of civilizations.
People are generally bad at predicting how the future will turn out because breakthroughs are usually paradigm shifts that redefine what you thought you knew before.

It wouldn't work, because not every genetic disease is inheritable.

The most obvious example of a genetic disease that is not inheritable is Down's Syndrome, as demonstrated by the picture in the OP

To a certain extent, otherwise nobody would have bothered building the more complicated and failure-prone design. However afaik the proximal source of this meme is that the trebuchet unit doesmoe damage than the catapult unit in Age Of Empires 2: Age Of Kings.

Just learn to blow your own glassware.
Learn to make pipes and bongs and sell them out of a suitcase in the parking lots of concerts (with a cooler of canned drinks) that you sell at a ridiculous markup because fuck you, supply and demand.
Make some quick easy cash, skeeze on concert sluts out of their minds on whatever chad and tyrone gave them, and maybe even get in to see some shows.

They WERE the cheapest labor source on the planet for a few hundred years. A global industry and empires were built on it.
