You post this and let us wonder how this might actually work without any pictures of the replicas??? :O

ETA: here are some examples in the video, unfortunately not the one in the meme...

I don't think so. Orbitals give you the spaces of highest probability! Electrons could be outside as well. And since it is based on probability it is definitely a useful model.

Electronic orbitals are regions within the atom in which electrons have the highest probability of being found.

I wish we wouldn't love under capitalism and creative people could just be creative for the greater good...

I know this is a meme and all. But there are so many people that talk earnestly about an anthropomorphized fantasy of the wood wide web. I just used this meme to vent a bit about it ;)

Like Nebula? I really enjoy it!

I really hate the anthropomorphization of these interactions. It completely blurs our understanding what is actually happening and it gets blown out of proportion.

Maybe it evolved from a predatory ancestor and didn't get selected for different position of the eyes?

Sounds like the movie Midsommar may have taken some inspiration from it haha

Yeah, I guess there are two sides to the problem here. People that do fraught on a level that is hard to perceive and those that do fraught on a grandiose level. I agree with all of your comments, especially what you say about how the harder to perceive fraught is actually more damaging to science.

But I guess the question initially posed why some people would do these high risk frauds. Why would someone say they've got a working room temp/low pressure supercomputer? Why would someone say they're able to turn anything into gold? As you say, these are just some spectacular outliers though. And some people are just in it for the short time of grandiosity and fame and don't care about the consequences I guess?

I would say that most people foraging wild plants in western societies aren't doing it to sustain themselves. It is usually has to do with learning more about their surroundings, to revive old knowledge or for fun. And as long as you double check, play close attention to detail and most importantly don't blindly follow an app you should be completely fine with this. (Well, foraging plants from the Apiaceae (the carrot family) is not really a good idea due to the close resemblance of most of its members.)

Well, if you are just avoiding Apiaceae (the carrot family) plants aren't that hard to ID safely and the likelihood of you poisoning yourself should drop by a lot. But yeah, you'd need to learn a bit about plants in the first place and not a lot of people are motivated enough to do that.

Apparently it is indeed referring to hemlock (Oenanthe crocata):

Contains oenanthotoxin. The leaves may be eaten safely by livestock, but the stems and especially the carbohydrate-rich roots are much more poisonous. Animals familiar with eating the leaves may eat the roots when these are exposed during ditch clearance – one root is sufficient to kill a cow, and human fatalities are also known in these circumstances. Scientists at the University of Eastern Piedmont in Italy claimed to have identified this as the plant responsible for producing the sardonic grin, and it is the most-likely candidate for the "sardonic herb", which was a neurotoxic plant used for the ritual killing of elderly people in Phoenician Sardinia. When these people were unable to support themselves, they were intoxicated with this herb and then dropped from a high rock or beaten to death. Criminals were also executed in this way.

(From Wiki page on poisonous plants)

But the main wiki page on Oenanthe crocata doesn't even mention this.

Wtf? If your girlfriend is annoying you by just talking then why don't you break up? This whole thing screams sexist tropes about women! Don't care if some of it is funny play on scientific terms but the underlying assumptions of gender roles are disgusting...

Mein Beileid :(

Fascinating read, thanks!

How does an 'equal division in spermatogenesis' result in sperms competing with each other? "The division happens asynchronically; if the tube is cut transversally one could observe different maturation states. A group of cells with different maturation states that are being generated at the same time is called a spermatogenic wave" (from Wikipedia). This doesn't sound like any chaotic or even violent competition to me? And there is a asynchronous division in spermatogenesis.

In contrast: "primary oocytes reach their maximum development at ~20 weeks of gestational age, when approximately seven million primary oocytes have been created; however, at birth, this number has already been reduced to approximately 1-2 million per ovary. At puberty, the number of oocytes decreases even more to reach about 60,000 to 80,000 per ovary, and only about 500 mature oocytes will be produced during a woman's life, the others will undergo atresia (degeneration)." (Also from Wikipedia)

So you could actually reverse this meme! Spermatocytes have a way to cooperate who goes first because only some are already fertile. On the other hand, oocytes really have to fight for their chance to ever get a go or else be degenerated.

So why is this meme not reversed? Because people tend to project their own norms and expectations onto everything! And this leads to a lot of wrong assumptions. People arguing about sex and gender often use these concepts of biology and what is 'natural'. But these are all only really projections of their expectations. Animals are not abiding to our gender norms. There aren't only male or female animals. Even archaeology has been heavily tainted by sexist assumptions on who has to be a man or woman.

This meme, just like bad science, is reproducing sexist assumptions. And now people who see this meme will think that there lies some truth within it, because the joke wouldn't work otherwise. So they'll assume that sperms really do compete for their opportunity while oocytes negotiate. But this isn't a fair or correct simplification of what's actually happening.

Isn't this picture of 'male' sperms violently competing with each other while 'female' oocytes peacefully cooperating anything but a projection of gender expectations?

This is a dumb meme that is only based on sexist assumptions of gender roles. And it sure isn't a science meme.

No. While corn truly is in the Poaceae, bananas are in the Musaceae. They are not even in the Poales! They are in fact more closely related to ginger and bird of paradise plants (all in the Zingiberales).

I mean, the joke is funny. But yeah, I feel the same way about the tone of the joke. Don't know why anyone would put that in their tinder bio and why anyone else should then engage with them...
