I forgot to post this last weekend, my She-Ra cosplay is finished! This week will be too rainy and cold to do a photo shoot so this is the best picture I have. Did anybody see me at Roc Con on Saturday?
When I lived in Rochester, a friend and I took our sketchbooks to the shores of the Genesee for some observational drawing- I think the place was called Genesee Park, and the University of Rochester River Campus is visible in the distance (the red buildings) I was using this piece to try and demonstrate about composition and the Rule of Thirds.
The blue pic was the view from our apartment, grad student housing University Park.
What humans and primates both know when it comes to numbers
For the past several years, Jessica Cantlon has been working to
understand how humans develop the concept of numbers, from simple
counting to complex mathematical reasoning. Early in her career at the
University of Rochester, the assistant professor of brain and cognitive sciences began studying primates in her search for the origins of numeric understanding.
In 2013, she, PhD candidate Steve Ferrigno, and colleagues at
Rochester and the Seneca Park Zoo made a surprising discovery: in an
experiment using varying quantities of peanuts, baboons (even as young
as one year of age) clearly showed an ability to distinguish between
large and small quantities of objects.
But the finding raised another question. To what extent might that
ability be influenced by other dimensions of those objects—such as their
relative surface area—in addition to their number?
Cantlon, Ferrigno, and two additional coauthors—Steven
Piantadosi, an assistant professor of brain and cognitive sciences at
Rochester, and Julian Jara-Ettinger, a postdoctoral researcher in brain
and cognitive sciences at MIT—published the results of a new study
suggesting that primates do, in fact, have the ability to distinguish
large and small quantities of objects, irrespective of the surface area
they appear to occupy.
Study subjects included both humans and primates: adults and children
in the United States; adults of the Tsimane’, a predominately “low
numeracy” cultural group that inhabits an area of remote rain forest in
Bolivia, and that has been long studied by Piantadosi and Jara-Ettinger;
and rhesus monkeys, a species with strong neural and cognitive
similarities to humans.
The researchers found that all groups showed a bias toward numbers over surface area in their estimations.
“This shows that the spontaneous aspect of extracting numerical
information likely has an evolutionary basis, because this has been seen
across all humans and also with other primate species,” said Ferrigno.
The study also showed that the bias toward the numerical dimension
was strongest in humans compared to primates, and was correlated with
increasing age and math education in humans.
“As children get older, they are more likely to represent numerical
information as opposed to other quantitative information,” Ferrigno
added. “Similarly, when Tsimane’ adults had more math education, they
were more likely to represent numbers as opposed to other dimensions.”
The study, published in Nature Communications, is an
exciting development for anyone interested in improving early math
education. Because the testing process was nonverbal, it could be
especially useful in assessing math abilities in young children. “It’s
very hard to test young children at age four on their math abilities
because it’s hard to differentiate what they know, and what they know,
but just can’t express,” Ferrigno said. “With further refinements, this
type of numerical bias test could in the future be an indicator of how
they are progressing in their education.”
The study is the first to compare number perception with a single task performed across a diverse testing population.
To test the relative importance of numerical quantities versus
surface area, researchers presented subjects with dot arrays, varying in
both the number of dots and the relative surface area they occupied.
For each array the subjects then selected one of two icons to categorize
the array as a large or small quantity.
To keep the task the same across groups, no verbal description of the
categories was provided; instead, subjects learned from nonverbal
demonstration by the experimenters, and trial and error feedback.
The tests with primates and children and adults in the United States
were conducted with touch screen monitors; Tsimane’ adults, who have
limited exposure to such devices, were tested with laminated printouts.
Cantlon says the study shows “that the initial step toward becoming
mathematically sophisticated likely had to do with focusing in on the
number of objects, not just total mass or size.” In a broader sense, she
adds, it shows “how humans got to be the way they are.
“This is about understanding human origins and how humans evolved thought processes that are mathematically sophisticated.”
Marvel Studios began building its expansive “cinematic universe” with Iron Man back in 2008. Since then, they’ve come to dominate the box-office in ways that demonstrate how much the “nerd culture” of my earlier years now represents mainstream pop-culture. I’ve always been appreciative of how Marvel has used that success to present positive views of science and scientists. But with that success, there can also come a kind of exhaustion with the genre. With Spider-Man: Homecoming, Marvel Studios has given us a smaller-scale story that recovers everything that made Marvel Comics so great.
Archaeological Hoaxes, Cryptozoology, and GIANTS!? Pt. 1 The Cardiff Giant
On October 16, 1869, workers in Cardiff, New York, unearthed what appeared to be the body of an ancient 10-foot-tall petrified man. Over the next several months, people flocked to catch a glimpse of the so-called “Cardiff Giant,” and many hailed it as one of the most significant archeological discoveries of the 19th century.
Concussions are mild traumatic brain injuries that can damage cells, cause chemical imbalances and disrupt the brain’s normal functioning in various ways.
Rest is still the critical primary prescription, especially in the first few days after injury. But increasingly, physicians at concussion clinics, concerned about young people who don’t recover quickly, have been managing patients differently, intervening earlier to pinpoint problems and prescribe targeted therapies.
It’s like physical therapy for the brain. “We don’t treat every stroke patient the same way,” said Jeffrey Bazarian, a physician with the sports concussion program at the University of Rochester Medical Center in New York. “We figure out: Do they have a language problem? Do they have trouble with their eyes? Trouble with their gait?”

Blue: Makes the people around you feel at ease. Dark blues are great for interviews and lighter blues for parties and social events.
Red: The colour we associate with passion. Research conducted by the University of Rochester found that men were more attracted to, and turned on by, women who wearing ruby red clothing. Again, this is great for parties – but not always at work.
Purple: This brings out our creativity, and is associated with self confidence, independent thinking and class. Purple is appropriate on almost any occasion.
Black: Conveys authority, so that people see you as being powerful, confident and competent. It is the colour of choice of authority figures (like the police), or for stylists, trend setters and icons.
Orange: This luscious, exuberant colour sends the message that the wearer is friendly, sociable, relaxed, and approachable. It’s great for social events – but not for important business meetings.
Green: This is the colour of happiness and contentment. It can be an instant mood changer, putting others around you at their ease. It is great for all occasions, and can be worn in both the daytime and the evening.
