Intense emotional experiences are more easily read in body language than in watching facial expressions. Facial clues in most studies rely on a set of stylized, recognizable expressions, which don’t reflect the expressions that people make in the real world.
Diverse languages, from English to Hindi, can trace their roots back 8,000 years to Anatolia (Asia Minor), a region that’s centered around modern-day Turkey. The study assessed 103 ancient and contemporary languages using a technique that’s normally used to study the spread and evolution of diseases.
David Skuse, a psychiatrist and an expert on language development working at the Institute of Child Health at University College London, encountered a mysterious ailment that affected a mother and son that had trouble following conversations and remembering words in their native language.
Bottlenose dolphins can understand the meaning and order of words, which can be conveyed through human hand gestures. It appears that now humans are also beginning to understand the language of dolphins as more than just a series of clicks, pulses and whistles. A new study published in the journal Proceedings of the Royal Society B shows how dolphins use their own signature whistles to introduce themselves to others when meeting at sea.
While a lot of adults will struggle trying to learn another language, kids can usually pick it up quite quickly. It’s always surprising how fast this can happen, especially if you make a point of fostering this as much as possible, within reason. It’s always important to keep things fun, doubly so if your child is quite young.
One of the marks of being a good prof is when they see that students didn’t understand something and go over it again. My algebra prof has made a habit of this, especially when he goes over stuff in class too quickly. This happened last week and left me quite furious. Someone must have mentioned something to the prof², and he went over what we saw in the last hour again. This took an hour out of the three-hour class. I appreciated. I realized that there were some undergrads in our class, who weren’t familiar with some of the more abstract concepts of category theory³. It was an issue. Class was great today. I was drinking my strong milk tea and noting stuff down. We saw direct sums and (co)universal objects. Having proofs done with commutative diagrams is so elegant and simple.
