WHAT IN THE HELL.
ive been staring at this for a good 10 minutes.. like i get it, but i dont.
remember when everyone on tumblr decided to completely ignore the law of conservation of matter
no, why the fuck was there 24 pieces to begin with, then he took one away, AND THERES STILL 24 FUCKING PIECES OF CHOCOLATE.
AHahaha Parece bruxaria, mas é só matemática AHhaa…
Vai treinando aí pra lograr o chocolate das crianças na Páscoa deste ano e vire um bandido pior que o Justin Bieber…
Top 5 misconceptions about evolution: A guide to demystify the foundation of modern biology.
Here is an infographic to help inform citizens. From my experience most people who misunderstand evolution are actually misinformed about what science is and how it operates. That said, here are five of the biggest barriers faced when one explains evolution - I have faced these and they are documented in the literature.
I hope you can build on my work and improve the communication between the scientists and the public.
Want to do more? If you want to donate to the cause of science education I suggest the National Center for Science Education http://ncse.com, your local university, or an equivalent organization. Volunteering at schools and inviting scientists into classrooms are two ways to encourage an informed society. Attend hearings if school boards start questioning evolution’s role in public curriculum. Raise a storm if anyone tries to ban science. Plus, it never hurts to reblog a well made evolution post.
Thank you followers for all your support!
Muito bom! Mesmo sabendo que ainda há muitas outras interpretações equivocadas sobre.
A helical TALE protein molecule wrapped around a double helix of DNA. TALEs stands for “Transcription Activator-Like Effectors”, they are produced by Xanthomonas bacteria when entering a plant cell. They manipulate the host cell by switching on certain genes that make the plant cell more susceptible to infection. TALE subunits bind to the nucleotides of DNA in a 1:1 ratio, and each subunit has a pair of amino acids that is specific to a single DNA base. This enables the TALEs to recognize specific DNA sequences and activate them.
Basilica of San Vitale - Ravenna (Italy)
The Church of San Vitale, the masterpiece of Byzantine art in Ravenna. Construction began in 526 by Bishop Ecclesius under the Ostrogothic queen Amalasuntha (d. 535) and was consecrated in 547 during the reign of the emperor Justinian. This octagonal church, built of marble and capped by a lofty terra-cotta dome, is one of the most important surviving examples of Byzantine architecture and mosaic work.

Sure, puppies are cute, but they’re also quite complex. At TEDxZurich, systems scientist Nicolas Perony uses YouTuber Robert Gann’s Scottie Pinwheel to show how complex social structures emerge from a group of individuals following a common rule (here: keep access to milk).
Watch Nicolas’s talk to understand more about the simple rules that drive some of the astoundingly complex social behavior of other animals — like bats and meerkats.
The Anatomy of a Constellation
In a cave system at Lascaux, southern France, Paleolithic paintings span the walls, dating back 17,300. Within the rocky tapestry, a picture of two bulls is adorned with clusters of dots—Orion’s belt, Taurus, the Pleiades and the Hyades clusters… What is thought to be the first recorded representation of the stars. For as long as we’ve walked this Earth, humans have been looking up to the sky and finding meaning in the randomness. Nearly every culture on Earth created patterns in the stars and attributed their own mythical stories to them, giving birth to what we know as constellations. Though they look like neighbours from our vantage point, in reality the stars that make up constellations might be thousands of light years apart. They’re just a matter of perspective, but they serve an important purpose: helping us navigate our way across the vast sky. On a dark night you can see over a thousand stars, so by recognising patterns we can break the sky down and move among the stars more easily. Constellations become mnemonics. Because of the relative movements of the Earth and Sun, constellations are divided into two groups: circumpolar constellations, which are always in the sky, and seasonal constellations, which rise and set according to season. Constellations change groups depending on your latitude, hence why the different hemispheres see different stars. In the past, farmers would have known which constellations signalled the comings of certain seasons, and so knew when to plant and when to harvest. Sailors and explorers have also long since been dependent on stars for navigation, and different cultures have all had different uses for their own stars. But in 1929, the International Astronomical Union consolidated them, officially setting out “modern” constellation boundaries and defining the 88 ones we know today, pictured above.
Paige Bradley created one of the most striking sculptures I’ve seen in recent times. Her masterpiece, entitled Expansion, is a beautiful woman seeking inner piece but fractured and bleeding with light. “From the moment we are born, the world tends to have a container already built for us to fit inside: a social security number, a gender, a race, a profession,” says Bradley. “I ponder if we are more defined by the container we are in than what we are inside. Would we recognize ourselves if we could expand beyond our bodies?”
Lera Boroditsky once did a simple experiment: She asked people to close their eyes and point southeast. A room of distinguished professors in the U.S. pointed in almost every possible direction, whereas 5-year-old Australian aboriginal girls always got it right.
She says the difference lies in language. Boroditsky, an associate professor of cognitive science at the University of California, San Diego, says the Australian aboriginal language doesn’t use words like left or right. It uses compass points, so they say things like “that girl to the east of you is my sister.”
If you want to learn another language and become fluent, you may have to change the way you behave in small but sometimes significant ways, specifically how you sort things into categories and what you notice.
Researchers are starting to study how those changes happen, says Aneta Pavlenko, a professor of applied linguistics at Temple University. She studies bilingualism and is the author of an upcoming book on this work.
If people speaking different languages need to group or observe things differently, then bilinguals ought to switch focus depending on the language they use. That’s exactly the case, according to Pavlenko.
For example, she says English distinguishes between cups and glasses, but in Russian, the difference between chashka (cup) andstakan (glass) is based on shape, not material.
Based on her research, she started teaching future language teachers how to help their English-speaking students group things in Russian. If English-speaking students of Russian had to sort cups and glasses into different piles, then re-sort into chashka andstakan, they should sort them differently. She says language teachers could do activities like this with their students instead of just memorizing words.
"They feel generally that this acknowledges something that they’ve long expected, long wanted to do but didn’t know how," Pavlenko says. "They felt that it moved them forward, away from teaching pronunciation and doing the ‘repeat after me’ activities."
Pavlenko points to research showing that if you’re hungry, you’ll pay more attention to food-related stimuli, and she says speaking another language fluently works the same way.
One’s native language could also affect memory, says Pavlenko. She points to novelist Vladimir Nabokov, who was fully trilingual in English, French and Russian. She says Nabokov wrote three memoirs: He published one in English, and when another publishing house asked for one in Russian, he accepted, thinking he would simply translate his first memoir.
"When Nabokov started translating it into Russian, he recalled a lot of things that he did not remember when he was writing it in English, and so in essence it became a somewhat different book," Pavlenko says. "It came out in Russian and he felt that in order to represent his childhood properly to his American readership, he had to produce a new version. So the version of Nabokov’s autobiography we know now is actually a third attempt, where he had to recall more things in Russian and then re-translate them from Russian back into English."
Boroditsky also studied the differences in what research subjects remembered when using English, which doesn’t always note the intent of an action, and Spanish, which does. This can lead to differences in how people remember what they saw, potentially important in eyewitness testimony, she says.
John McWhorter, a linguist at Columbia University, acknowledges such differences but says they don’t really matter. The experiments “show that there are these tiny differentials that you can find that seem to correlate with what language you speak,” McWhorter says. “Nothing has ever demonstrated that your language makes you process life in a different way. It just doesn’t work.”
As an example, he refers to modern speakers of a Mayan language, who also use directions that roughly correspond to compass points, rather than left or right. Researchers asked people, most of whom only knew this language, to do tasks like memorizing how a ball moved through a maze, which would have been easier had they thought about it in terms of left and right, rather than compass points. The participants were just as good at these tasks and sometimes better, leading the experimenters to conclude they were not constrained by their language.
Boroditsky disagrees. She says the counterexamples simply prove language isn’t the only factor affecting what we notice. Like studying to be a pilot or doctor, she says, learning to speak a different language fluently can also change us, and this means we can learn those changes, like learning any other skill.
"It’s like a very extensive training program," Boroditsky says. "There’s nothing exotic about the effects that language has on cognition. It’s just the same that any learning has on cognition."
