GO MO MATH - Math Museum of NYC

squarewheeltrikespherestickies

We arrived at the Museum of Math one hour before closing on a Saturday in late summer and zipped through it. The exhibits deserved more than the limited time we gave them and these videos, summarized below, will help us understand what we experienced with the intriguing interactive demonstrations. GO MO MATH!

SHAPES OF CONSTANT WIDTH You sit on a boat-shaped platform above a field of irregularly shaped objects and yet glide rather smoothly over them because these objects, such as the Meissner tetrahedron, all have the same constant diameter whichever way they roll.

SQUARE WHEELS, CATENARY CURVES You ride a tricycle with square wheels without any problem. This is because the surface you are riding on is catenary curved (hyperbolic cosine). And, for any shaped wheel, there is a corresponding road that will facilitate locomotion.

A SPECIAL SQUARE When you and others step upon this large lit-from-below square, the square divides into as many differently colored geometric areas as there are people and each point within any one’s area is closer to that person than to any one else.

THE HUMAN FRACTAL TREE On a projection screen, a copy of your body is copied where your arms are and on those projections, your body is again copied where your arms are and so on, forming a fractal pattern of you as a tree.

SOLIDS OF REVOLUTION SLICED TWISTED, REATTACHED AND ROLLED Solids of revolution are cut along the axis of symmetry and then twisted and reattached to form an asymmetric object which then describes a distinct path when it rolls and it’s your job to match up each object with the trail it makes.


Siri performs in their Odyssey of the Mind

Chestnut Hill Garden Festival 201305

Effervescent Sammi Baker and her partner Nathan Hyer brought their paper Mache puppet “Siri” out to Chestnut Hill Garden Festival to raise funds for “Odyssey of the Mind.” The Plymouth Whitemarsh high school students participate in this extracurricular activity in which school teams compete against each other in creative problem solving and have to keep their builds within a set budget. (Siri appeared in their competition skit.) Their team (which also includes Cooper Smith, Colleen McFillon, Ryan Silverthorn, Michael Krone and Diana Westerfer) placed fifth in the Pennsylvania state finals but that wasn’t quite high enough to entitle them to a trip to the globals this year.

Paintings inspired by neurons

kirsten fischler's neural imagery

Kirsten Fischler captures neuronal imagery in her paintings. She has been inspired by her partner, a neuropathologist. Neurons are nerve cells that communicate information electrically/chemically with other cells. In her artist’s conception neurons are the “essence that occurs inside the mind that helps develop the mind” or “the spark that makes the mind happen.” Philadelphia Open Studio Tours, Francisville.

Losing the sense of smell

A young woman who realized in college that, without a doubt she wanted to become a chef, grabbed the offer to start as the dishwasher in a famous Boston restaurant and she loved it, covered in butter, chicken fat, sweat. One morning, on a morning jog before work, she was hit by a car and among other bad injuries, had shattered her skull. Two weeks later, making a recovery at her father's house, she made a bad discovery - her sense of smell was gone. Heat was all she sensed of the cinammon-laced apple crisp, a favorite dish, when it was just drawn from the oven and held under her nose.

Birnbaum went on to study the sense of smell and her experiences with its loss(a condition called "anosmia") and wrote about in her 2011 book,"Season to Taste." Along her journey she spent much time with the olfactory scientists the Monell Chemical Senses Center with whom she presented "Forgotten Sense: Exploring a World Without Smell" as part of the Philadlephia Science Festival.

Also attending the event is a doctoral student in information sciences at Drexel University, (shown below) who speaks about her own experience with anosmia.

Exploding Carbon Dioxide

co2

Fred Schaefer of the University of the Sciences, conducts an explosion experiment with liquid carbon dioxide at Earth, Bread and Brewery in Mount Airy, Philadelphia. Tonight's experiments were part of the 10 day Philadelphia Science Festival  and here he was assisted by Faye Flam, who writes about evolution in her "Planet of the Apes" column in the Philadelphia Inquirer. Schaefer holds "tabletop science" evenings once a month at the restaurant! Watch video here.

 


Brings deconstructed astronomy book to science high school interview

My book is called a deconstruction book and it’s like when you get a plain old book that nobody reads, sits on the shelves at stores and stuff and getting it and exposing the information in a 3-dimensional work of art. WHAT’S THE BOOK ABOUT? It’s about astronomy, all about the planets, the moons, suns, stars… I can name you everything inside. Right here there’s an asteroid and it’s called Hyperion and Hyperion back in Greek mythology was one of the Titans of the East.

Re Clamming Barnegat Bay

Re Clam bay

Martin Sedlacko, of Forked River, New Jersey volunteers with ReClam the Bay, an environmental organization with an educational focus that grows up seed clams and oysters until they are large enough to be transferred to protected reefs in Barnegat Bay.

The native oyster and clam populations died off substantially in the 1950s and ‘60s due to land development in the shore community and environs, Sedlacko explains. One significant factor is eutrophication; nitrogen (found in fertilizers, acid rain) from runoff contributes to excessive underwater plant growth. In the subsequent dieback and decomposition process, bacteria consumes the oxygen the shellfish depend on.

On Monday afternoons, volunteers gather at a shellfish station on Barnegat Bay off of 24th street in Seaside Heights, not far from the extensive Island Beach State Park on the south side of Long Beach Island. They clean the growing shellfish and introduce bay water into several tanks called “upwellers.” The juveniles feed on plankton in the water.

The Seaside Heights station is one of ten such locations on the bay that participate in the Barnegat Bay Shellfish Restoration Program, a partnership between Rutgers University/Ocean County Cooperative Extension and the New Jersey Department of Environmental Protection.

Employees from Subaru of Cherry Hill complemented the regular volunteer contingent at the Seaside Heights station on a recent Monday afternoon. In the morning the employees had participated in a bay cleanup. According to one employee, Subaru partners with the Ocean Conservancy because this kind of volunteering is a good fit with its brand and the values held by its customers.

Tasting like a lion

in lions mouth.jpg

Guests sample six different concoctions to understand how animals taste. Cats don't taste sweet so a sweet substance was tasted followed by a sweet blocker followed by another draft of the same sweet substance- which tasted like not worth eating or drinking! At the Philadelphia Science Festival event at Rembrandt's Restaurant produced by the Philadelphia Zoo and Monell Center where they study the sense of taste. Watch video here.


Body odors signal threat?

Amy Gordon,left, a first year grad student who works at the Monell Center, welcomed guests to a Philadelphia Science Festival program on how animals, smell and taste at Rembrandt's Restaurant and Bar. Gordon studies how humans communicate with body odor, especially how a stranger's body odor may influence threatening visual stimuli from the stranger.
