Moviegoers attending the Chestnut Hill Film Group’s inaugural screening of the season this Tuesday evening were delighted by the artful musical accompaniment of veteran keyboardist Don Kinnear. Kinnear improvised as he watched, for the first time, two silent short films chosen by Jay Schwartz (founder of the Secret Cinema) and employed the operatic style of playing and interweaving themes assigned to different characters for the silent main feature he had seen before, W.C. Fields’ 1926 “It’s the Old Army Game.” With his electronic keyboard and a laptop loaded with a digital version of the Wurlitzer organ of the Virginia Theater in Champaign, Illinois he reproduced the music, sounds and special effects (“toy counter”) the original audiences in the 1920s may have experienced.

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.

“That’s what we’re looking for- the waypoints”
“It’ll say the gecoache is that way but the trail goes this way or this way.”“We won’t send you through the woods bushwhacking”
Destination- “Soggy Bottom” at the troll bridge
Garmin device accidentally restarts
Device now says ready to navigate
On the trail to the cache
“It must be around here”
What’s inside the cache which is a canteen?
Is it a toy toilet or a stamp out of ink?
No, it’s a star punch to punch our paper to prove we found it.
Another group arrives at Soggy Bottom
Excitement back at campfire
“How was your first geocache experience?”
“Sweet. Marshmallow- sweet, get it?”
Found 6 caches!

The story goes that in 1853, a restaurant patron at a New York resort who complained of a soggy french fry gave rise to the invention of the potato chip. Tori Messaros, a college biology major on summer break, gives five hour long tours a day of the Herr’s Snack Factory in Nottingham, Pennsylvania near the Maryland border. And she is just one of many guides- tours start every 20 minutes 9 to 4 daily except Friday. For Messaros, it’s a family affair: her mother runs the tour center. Large glass windows in corridors above the production floor offer real time views of the different production stages. Our tour started with tortilla chips and then moved on to potato chips. Except for a handful of workers in the box packing area, the factory rooms otherwise appeared eerily empty with only one or two workers making the rounds or attending to a machine. The machines operate around the clock with three shifts of workers a day. Leftover corn kernel and potato peels get recycled to the Herr’s farm and potato starch from the slicing process gets sold. The time it takes a potato to enter the chute, get washed, peeled, sliced, rewashed, fried, seasoned and packaged, takes six minutes, Messaros says. But it took only a couple of minutes for our group to devour just off-the-line hot chips and pick up two small complementary bags of chips before being dropped off in- where else -the factory gift shop!
PECO is replacing the existing electric meters in the neighborhood with new remote controlled smart meters using Radio Frequency (RF) transmission. Installer Peter Paige stopped by one morning, as scheduled, to make the 15 to 20 minute switch-out.
This is the process: Wearing fire resistant clothing, Paige first dons personal protective equipment: a hood, helmet and goggles to guard against a flash which might occur should he touch a live spot inside the box. He credits the protective gear with saving him on more than one occasion!
Paige then records the old meter number and reading and the new meter number and reading on a multifunctional, handheld electronic device. Then pulling off the old meter, the lights in our utility room and house go out. With a helmet-mounted lamp lighting the box, he tests the voltage. Trilling sounds indicate it’s OK. He snaps in the new meter and attaches a seal; its thin gauge wire can be cut but if it is discovered so, will indicate tampering.
With the handheld, Paige then takes photos of the old meter. Melting, burning or char on the plastic back of the old meter will indicate an electrical problem that a special PECO team will follow up on. And lastly he beams a red light at the meter to activate it. And it’s on to the next job. Paige says his appointment team can do up to 15 or 20 or more on a good day.
The smart meter allows PECO to turn it off in case of either emergency or delinquency. The new meter also has a sensor that detects overheating, surges or other improper conditions, can signal PECO and can shut itself down. Soon, a website will be available for customers to monitor and analyze their electric usage and achieve savings.
A “New Metering Technology” handout Paige provides explains that the new meters are being installed in accordance with the requirements of Pennsylvania Act 129 of 2008. In addition to the quick detection and correction of problems, the new technology is expected to provide the basis for new products and services. The handout also addresses consumer concerns about the level of Radio Frequency (RF) emitted by the meter and potential concerns about the privacy and security of the information captured.
While taking a leisurely, easy bike ride along the relatively flat Forbidden Drive, my daughter and I were amazed to see a young man atop a unicycle on the opposite shore of the Wissahickon Creek, tooling up and down a hilly, narrow trail. High-schooler Peter Hildebrandt took up mountain unicycling after a knee injury ended his running career. With his high end, fat-tired, disc-brake equipped mountain unicycle, he meets regularly in the Wissahickon with other unicyle friends and enthusiasts and is preparing to compete in the 2013 North American Unicycling Convention and Championship to be held in Butler, Pennsylvania this coming July.

I’ve been retired now for about twelve years. And ever since I’ve been retired I’ve wanted to do something. I’m not a lay home watch soap opera kind of girl. I ran into a place called non-profit technology resources down near Spring Garden and Stan introduced me to recycling. And what I do is the donations that have come into the YWCA where I started and Malt Computer Volunteer Group, with the donations that come in, they were just sitting around. So I decided to tinker with and fix them.
As of the past four years we’re a Microsoft authorized refurbisher. We’re licensed by Microsoft to refurbish computers and install licensed products. Because we’re an authorized refurbisher, that means I’m obligated to wipe any and all hard drives. So I can assure people if they want to donate it or someone comes in and says I want to donate and I want my data, I’ll open the computer up and pull the hard drive out and hand it to them. Because when I re-image it, it has to be wiped. I have other hard drives.
You used to be able to put computers out on the sidewalk. Now you can’t do that. Also industries can’t dispose of their computer equipment the way they used to. So they donate it. They say you come get it. No you drop it off because I know they’re saving money (plus they’re getting a tax deduction} because they don’t have to pay for disposal.
My concern is since I’m a grandmom my concern is with schoolchildren, middle school through high school and college students. When I get donations of laptops, the college students are first on the list AT REDUCED PRICE? At minimal price. Especially a high school student who comes in and they’re honor roll. They get a whole PC for twenty bucks. AND HOW DO THEY FIND OUT ABOUT YOU? Usually word of mouth. Everybody knows “Miss Wynnie, the computer lady.” Wynne Hill, Summit Presbyterian Church, Mount Airy.
Jim Leonard combats the debilitating effects of multiple sclerosis with the assist of an advanced mobility vehicle. No glorified “seat with wheels” Leonard’s device can zip through a mall at 6 miles per hour, recline him horizontally to relieve pressure or elevate him so he can reach the microwave in his kitchen or stir a pot. While waiting to be seated for breakfast at Mainely Meat in Bar Harbor, Maine, Leonard stopped short of demonstrating the 360 degree wheelies he can do with his sophisticated chair. Watch video here.
Workmates Stephen McShane and Jarek Heljak (seated on other side of table) of Northeast Philadelphia talk about the nuclear plant crisis in Japan and energy generation alternatives. McShane has a Japanese friend whose parents in Sendai were far west enough to have only lost power. He expressed grave concerns about water and food contamination and favors solar or wind energy. Heljak, who says his native Poland relies on coal and has no nuclear plants due to the expense, favors nuclear. Starbucks Coffee, Chestnut Hill. Watch video interview here.
