so we have a conversational safeword in my group of friends and it’s great, idk why more people don’t do this. whenever someone wants a subject to be dropped immediately no questions asked we just say “spleen” and we stop immediately and it’s a really good way to avoid crossing the line between teasing friends and genuinely upsetting them by accident, or stopping debates from turning into actual arguments

Wait but no this is actually a brilliant idea. 

When I was a little baby high school student, I used to do the Living Chessboard at our local Renaissance Faire. We always used “forsooth” to indicate if someone was actually injured and needed to quickly end a choreographed fight. It was also very useful when doing little street improvisations because if someone tried to stop you, you could say “forsooth good sir, I must leave.” and they knew you couldn’t do a scene right then. We all used it in real life too, to say “no really” and it was amazing because there was a word used in a casual setting that meant “I’m not playing, I need you do listen to me.” So if someone tried to pick me up or tickle me, I could say “forsooth stop.” And I was instantly obeyed. I had “forsooth” long before I learned what a safeword was, and having a non-sexual safeword for everyday use amongst a circle of friends was the best thing ever. It made me feel very safe and listened to, even as a tiny 14 year old. Because let’s be honest, 14 year old me was teeny tiny and adorable and it’s easy to coo at kids when they say “no don’t pick me up!” but to have a word that every single person respected to mean “whatever I say after this MUST be listened to” was amazing. It gave me a definitive voice when it would have been easy to dismiss me.

So basically having platonic safewords is awesome and I’m all for it.

Previously, I’d only seen the first two panels and assumed it was the complete comic.

This version is much better.


ADDENDUM: As this approaches 100,000 notes as of this writing (less than three days after it was first posted), there are a couple of things that need to be added, and I prefer to add them to the original post, rather than to a reblog.

FIRST… there are a number of reblogs and replies–mostly from white males who see their precious capitalism threatened–that ignore the point of the comic and go after the fact that the people pictured didn’t pay for a ticket to get into the stadium.

If you need to see the point without the barrier (hah) of this particular comic, imagine this scenario instead. The scene is the maternity ward of a hospital. A joyful father is looking into the nursery window to see his newborn daughter…

  • First panel (equality): The father’s older child–a son–is standing next to him, wanting to see his new little sister. The boy is too short and can’t see into the window, but he and Dad are on equal footing. This is “equality.”
  • Second panel (equity): Dad picks the kid up so he be at an equal height and peer into the window at his sister. This is equity.
  • Third panel (removal of the systemic barrier): Instead of a window, the entire wall is made of transparent glass. The nurse brings the newborn over to show dad, and then squats down to show little brother as well.

Better? Everyone complaining about them watching the game “illegally” can now shut the fuck up.

SECOND… there have been a couple of inquiries about the source. Turns out, the original was indeed the first two panels only. It was an MS Paint image thrown
together by a business professor named Craig Froehle to illustrate the difference between
equality of opportunity and equality of outcomes. The three-panel version featuring the removal of the barrier is one of many adaptations.

For the somewhat fascinating story behind the original and how it came to be adapted in myriad ways, see https://medium.com/@CRA1G/the-evolution-of-an-accidental-meme-ddc4e139e0e4

That’s it!

Guys, this is not a drill. Antarctic scientists need you to study photos of penguins to help them figure out how climate change is affecting these stumpy little flightless birds.

Scientists from the UK have installed a series of 75 cameras near penguin territories in Antarctica and its surrounding islands to figure out what’s happening with local populations. But with each of those cameras taking hourly photos, they simply can’t get through all the adorable images without your help.

“We can’t do this work on our own,” lead researcher Tom Hart from the University of Oxford told the BBC, “and every penguin that people click on and count on the website – that’s all information that tells us what’s happening at each nest, and what’s happening over time.”

The citizen science project is pretty simple – known as PenguinWatch 2.0, all you need to do is log on, look at photos, and identify adult penguins, chicks, and eggs in each image. Each photo requires just a few clicks to identify, and you can chat about your results in the website’s ‘Discuss’ page with other volunteers.

sigh … okay, I go again 

I think there is a divide between those who were discriminated against and bullied and abused for being weird or “immature” or other things like that but were able to succeed academically and those who weren’t able to succeed academically and faced discrimination and bullying and abuse for being “stupid”. 

For the first person, when they’re being constantly knocked down by some jerks, being able to say “well, I’m smarter than you” is really empowering and liberating. And I’m not advocating for taking that away from anyone who has it now, I’m not. 

But where do the other kids go? The ones who can’t say “at least I’m smarter than you” because by every traditional definition of “smart”, they’re not. Their bullies are the smart ones.  

In my experience, telling a kid who is not succeeding in school, that “well really you are smart. you’re a good artist and thinker and all these things”, doesn’t help. Because the kid knows, they feel like they’re being placated. Okay, you say I’m smart, but I know I’m not what really smart is. I can’t do what being really smart means. Sure, I’m good at those things but I’m still not like the kids who are really smart

And that’s why I’m arguing that, going forward, if we continue to define intelligence by these specific, narrow things, people are going to get hurt by being told “you’re smart” with no other qualifier. The kids who can’t succeed in an academic environment, who are surrounded by this traditional idea of intelligence, aren’t going to believe you when you tell them they are, because in every other way they’re being told they aren’t. They’re going to lose out. 

And the “smart” kids may be even worse off. Because what if one day they lose the skills that defined them as smart, or their other struggles suddenly outpace their intelligence? They really lose out, cause in one fell swoop they lose the thing that defined their worth. 

So what I’m saying is, in the future, if we tell kids from the get-go, “intelligence isn’t something you are, it’s something you apply. to anything. and everyone has the ability to apply it to different things, because each of our brains have different blueprints, and no one thing is better than the other, and no one thing takes more or less intelligence,” then we’re going to be much better off. 

Don’t get rid of the concept of intelligence, just get rid of how we conceptualize it. It’s not a trait, it’s a universal tool, applicable in different ways by different people.

Whenever someone tries to claim that evolution is a lie, I send them a picture of platybelodon.

1. It’s an excellent example of transitional evolution.

2. It’s a mess who would intentionally do this and why

3. It makes them piss themselves a little.

“Evolution is just a theory-”

I busted out laughing in the middle of Christmas dinner. This is the best post of 2015 that I’ve seen. 

Not to be rude, but evolution is just a theory, albeit a probable one.

You can’t prove it, the only thing you can do is disprove it, which is what good scientists are supposed to do, try to disprove their theory.

Ah, but that’s the thing; A scientific theory IS a proven fact, and evolution is a very good example of an undeniably true one!

I’ve been meaning to write a post about what the meaning of a scientific theory is, and this seems like a good opportunity.

In science we have theories, and we have laws. It’s a very common misconception that a scientific theory is a an unproven hypothesis. This is understandable, but leads to a fundamental misunderstanding of how science works. A scientific theory isn’t the same as what we commonly refer to as a ‘theory’. Here’s a definition:

A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation.

Compare this to the definition of a scientific law:

A scientific law is a statement based on repeated experimental observations that describes some aspects of the universe. A scientific law always applies under the same conditions, and implies that there is a causal relationship involving its elements. x

This means, basically, that a law summarizes observations about some sort of natural phenomena (usually mathematically). A good example is Newton’s law of gravity! 

Newton’s Law of Gravity explains through mathematics how different bodies react to each other because of this force we call gravity, both on earth and in space, but it doesn’t explain why it happens or even what gravity actually is. No explanation, therefor a law!

Then we have theories, which not only document phenomena, but give explainations as to why these phenomena happen and what they are. A scientific theory requires more testable evidence than a law, and usually encompasses multiple laws and explains them more thoroughly. For example, Albert Einstein’s theory of relativity.

Newton’s law of gravity was testable, but it was only after Einstein proposed the theory of relativity that we started to understand what gravity actually is and how it functions. Einstein was able to give us explainations mathematically for why the laws of physics work as they do. Explanations for how it worked, therefor a theory!

(It’s also important to remember that a scientific theory and a scientific law are two very different things, and one can never become the other. A theory will always be a theory, and a law will always be a law.)

One of my favorite examples of this is the laws of Mendelian inheritance. 

Long before we knew what genetics were, farmers were breeding for favorable traits. They didn’t know where they came from or how they were passed from one organism to the next, but they knew that if they bred a large dog with another large dog, they’d get large puppies, and they knew that if they bred only their best produce that their plants would produce better produce in the future.

Gregor Johann Mendel started conducting experiments by hybridizing pea plants, and was able to prove that this consistently happened. By doing this he created three separate laws that all fall under the Laws of Inheritance; The Law of Segregation, the Law of Independent Assortment, and the Law of Dominance. It gets a little complicated here and I’m not an expert on DNA, but I’ll try to summarize.

The Law of Segregation states that all organisms contain two alleles for each trait, and that those separate during meiosis so each gamete only contains one of them. That means that offspring receives a pair of alleles from its parents for each trait, resulting in one allele for each trait from each parent. For example, a calico cat and a tabby may breed and produce 4 tabby kittens, but all of those kittens will also carry the genetic information of a calico.

The Law of Independent Assortment states that alleles for these traits are passed independently of one another during gamete formation. For example, if the calico is a manx and the tabby is a scottish fold, the kittens can inherit a short tail without inheriting their calico parents coloring. They can also look entirely like one parent despite carrying the genetic information of both. Each trait is passed independently of all other traits.

The Law of Dominance states that recessive alleles will be masked by dominant alleles. For example, blue eyes in cats is a recessive trait. Therefor even if the scottish fold has blue eyes (is a carrier and affected), the dominant trait eyes of the manx will determine the color of the kittens eyes, and we’ll only have a slim chance of producing affected, blue eyed kittens if the manx also carries the recessive blue eyed gene, and those genes line up.
(If I’ve made any mistakes here, I’d appreciate someone with more knowledge on genetics letting me know)

But you’ll notice he didn’t show how or why this happened, he was just able to observe it and prove that it did. It wasn’t until the Chromosome Theory of Inheritance was discovered that we could explain why. This was the theory that explained that chromosomes are what carry genetic material and pass these traits from one generation to the next. 

It’s a fundamental, unifying theory of genetics that shapes how we conduct our science today. This theory is the basis of genetic engineering, which has had a huge impact on modern science. Just for example, the manufacturing of drugs (insulin and vaccines!), gene therapy, the genetic engineering of lab animals, and, most famously, agriculture. AKA, GMOs.

This leads into another requirement of a theory; Being supported by numerous other fields of science. Genetics is one of the sciences that hugely supports the Theory of Evolution. This is how we’ve been able to sequence DNA and discover how closely all life on earth is related, and how the DNA of humans and chimps is nearly identical.

x
And this isn’t the only field of science that supports the validity of the Theory of Evolution. 

We have radioisotope dating! Isotopes make up all matter on earth, and by measuring the decay of radioactive isotopes, we can date rock layers. We can do this because we know the rate of radioactive decay. This is how we know that the Earth is around 4.5 billion years old. We’ve used this to date fossils and prove that transitional forms came between connected species, and that humans and modern animals didn’t live alongside dinosaurs.

We have paleontology! The fossil record shows extremely detailed evidence of evolution occurring. Evolution is so accurate in its predictions that there’s never been a single fossil found in a place that it shouldn’t be. For example, the transitional fossils between dinosaurs and modern birds is found right in the middle, exactly where we’d expect it to be. So is the ancestor of platybelodon, and its relatives as they became our modern elephants!
We’re able to predict so accurately where fossils should be located that we’ve been able to pick sites to excavate based entirely on that, then find the fossils we expected! Predictive power is a huge part of a proven scientific theory.

We have molecular biology! Which proves that gene sequences among extremely different organisms are still related. The basic structure of all DNA on the planet is in the form of the double helix, and while we predictably have nearly all the same DNA as our primate cousins, over half of our DNA is also identical to banana plants!

Then we have embryology! When we compare embryos, not only are most animals nearly indistinguishable from each other, but we see holdover traits from our previous ancestors. The most compelling examples are the fact that human fetuses, and all other mammals, have gill slits as embryos. In mammals these develop into the eustachian tubes and the ear canal, while they continue to develop into gills in fish. Humans also have tails and yolk sacs as embryos! (Also look up lanugo in fetuses, very interesting and shared among other mammals)

Then there’s biochemistry! The basic chemistry that occurs in the cells of all life on earth is extremely similar, and shows that all modern organisms had a common ancestor. For example, all animals have enzymes and hormones. Trypsin is just one that’s found in everything from humans to sea sponges.

Then biogeography! The fact that groups of organisms that are related are all found near one another is more evidence for the validity of evolution. If life didn’t evolve, there’d be no reason for certain life to only exist on certain continents, or for species to be distributed in a pattern that reflects their genetic relationships with one another.

Modern observations are extremely helpful as well! This is why we now see antibiotic resistant strains of viruses, elephants becoming less likely to have tusks because of poaching, and the peppered moth becoming darker to better camouflage itself during the industrial revolution.

There are others, but I’ll end with comparative anatomy, which is one of the coolest, imo. (I’m probably biased because I collect bones lol)

x

When you compare the skeletal structures of vertebrates, we have extremely similar structures regardless of how wildly different our environments and behaviors are. The skeletal structure of a fin is hardly the best way for a fin to be designed, but because whales evolved from terrestrial mammals, they adapted using what they had. (we can also show the full evolution of cetaceans through the fossil record, which is very cool if you want to look it up.)

This is true in non-mammals as well. An excellent example is the laryngeal nerve! In fish, the nerve makes a direct line from the brain down to the larynx, which is practical and to be expected. In animals that developed longer necks, however, we see that the nerve is trapped under the aortic arch!

x

The nerve had to evolve with us as we evolved from our aquatic ancestors, so our laryngeal nerve is forced to not go from our brain to our larynx, but rather to take a detour into our chest and around the aortic arch before doubling back! 

This is amazing in giraffes, where the nerve is nearly 15 feet long because it was forced to grow as the giraffe’s neck did, and now takes a detour down the entirety of the giraffe’s neck and around the heart before returning the the larynx, which was its destination.

x
There are mountains more evidence, but it’d take a lifetime to cover it all.

 
So you’ve got the way a theory works a little backwards; A theory only remains a theory when it can’t be disproven, and therefor is proven accurate. For a theory to be a theory, it has to be proven true. This is why we teach other theories, for example:

Plate tectonics theory: Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen “plates” that move around across the earth’s surface relative to each other, like slabs of ice on a lake.

Cell theory: In biology, cell theory is a scientific theory which describes the properties of cells. These cells are the basic unit of structure in all organisms and also the basic unit of reproduction.
and

Atomic theory: In chemistry and physics, atomic theory is a scientific theory of the nature of matter, which states that matter is composed of discrete units called atoms.

In your tags you state that evolution is a theory, and therefor can’t be taught as fact. I’m sure you don’t believe that we shouldn’t teach about the existence of atoms and the function of cells because they’re ‘only theory’, so I hope this makes clearer why that notion is flawed. We accept all of these as true because we know factually that they are. 

The reason that evolution is given such intense scrutiny is because it disproves the notion that humans are a separate, superior entity to all other life on earth. This is a blow to some egos and contradicts some people’s religious beliefs. The discovery that Earth wasn’t the center of our solar system, much less the universe, was met with the same sort of scrutiny for the same reasons. The ever building proof that we’re only a tiny flicker of what has been and will be in the universe inspires strong reactions in people, for good or bad. Personally, I find it endlessly interesting!

Also, to clarify, attempting continually to disprove a theory wouldn’t necessarily be good science. When you have a theory like plate tectonics, trying to disprove it at this point really isn’t a good use of your time. We know how it works, we’ve seen it working, we can predict how it’ll work, we can prove this is how mountains formed and earthquakes happen and continents drift. Being critical and making sure things line up properly is good science, but trying to continuously disprove something we know to be fact is a waste of energy and resources.

Evolutionary theory is the basis of everything from vaccines and Glofish to agriculture, modern medicine and decoding DNA. It’s so ingrained in everything that we do, that it’s vital for people to understand how it works. 

If it were proven false tomorrow, it’d take a lot of other fields of science down with it. But most of us are understandably doubtful that it’ll happen, because it’s been undergoing this same intense scrutiny since Darwin published The Origin of Species in 1859. That’s an awfully long time and a lot of scientific advances for there to have never been a single, solitary piece of evidence that disproved it.

To stay on theme, let’s end with a platybelodon family reunion.

THANK YOU! It’s important to be aware that the scientific definition of a theory differs drastically from its colloquial usage.

This entire thread was a train ride of wonder. Props to @madsciences!

S-s-science 😀
