Saturday, September 1

7:00 – 8:00pm
Description:Drexel University’s Professor Michael Yudell and his academic friends team up with some of Philly’s best improvisers to create a full hour of hiliarious improv comedy inspired by real stories from history and science. Professor Yudell and his friends will exploit every ounce of their tenure to lecture on a wide variety of topics and the “students” will warp each lecture into outrageous scenes on the spot! Don’t be late to Study Hall!

KOKO the Grorilla Dead at age 46

Koko the gorilla was found dead Tuesday. The Gorilla Foundation released a statement that the lowland gorilla, who mastered sign language, died in her sleep. Koko had a vocabulary of about 2000 words and communicated with humans.

Researcher and one of Koko’s keepers, Francine Patterson, had hoped that Koko would mate and have children. She wondered if Koko had offspring would she teach them sign language? But unfortunately, Koko never mated and never had children.

She was friends with Robin Williams and Fred Rogers. Researcher Francine Patterson said that Koko was quiet and very thoughtful when told of the death of Robin Williams. Koko also met Flea, the bassist in the Red Hot Chill Peppers, and the actor Betty White.

Koko was very fond of cats and had her own “pet” kittens throughout her life.

She appeared in several documentaries and appeared on the cover of National Geographic. The Gorilla Foundation said: “Koko touched the lives of millions as an ambassador for all gorillas and an icon for inter species communication and empathy. She was beloved and will be deeply missed.”

Hidden Figures

hidden-figures-taraji-p-henson-as-katherine-johnsonI saw the movie Hidden Figures today. Fabulous movie. But why did it take so long for me to know about these women?

Me of all people should have known about these women. I am a huge fan and “student” of modern space exploration. I do workshops for teachers about the history of the American space program and an as a science teacher in middle school I taught a class called “ Rocket Science.” We made timelines and posters and did research about the Apollo and Mercury missions. Apollo 13 is one of my favorite movies. The names Alan Shepard, John Glenn and Neil Armstrong are very familiar to me. Why did I never hear about the African American women mathematicians who helped NASA and the USA win the space race? How could that be? I thought everyone involved with NASA was a white man.

Before there was NASA there was the National Advisory Committee for Aeronautics. Before space flight there was aeronautics, and airplane flight was a new, very mathematically intense field. This was way before the computers we have today. It was even before we had calculators. There was a lot of data associated with testing planes, making planes better, and improving planes. The engineers involved felt if there was a huge “computing pool” of people, this might be an efficient way to process the data that came from aeronautic research. They hired smart math graduates, all women, all white, until 1943. Then, with the demands of World War II they began hiring African American women. Pressure from A. Phillip Randolph, a civil rights activist, to FDR, resulted in Executive Order 8802 which said: There shall be no discrimination in war industries and the federal government. Within 18 months after Executive Order 8802, a segregated group of African American women mathematicians began working at Langley Memorial Aeronautics Lab in Hampton Virginia.

The facilities were segregated: segregated bathrooms, lunchroom and workspaces. These women were called “ computers”— – someone who made calculations and crunched numbers for the engineers developing aerospace technology. Some women would analyze data from flight simulations, while others did theoretical work. There was a full spectrum of duties, everything from simple calculations to high-level math.

The story is so exciting but unknown, until now. It took courage, talent and lots of guts to do what they did.

Run, don’t walk to the theater and see this movie. Educators show this movie and discuss its significance!

Change of State

statesWhen it snows we complain that we have to shovel the snow and clean it off our cars. We worry about driving conditions and are afraid we might fall on the ice that accompanies the snow. But if we wait a few days, the temperature will rise, and it will all melt and be gone. When it rains we complain that we are wet, that our roof is leaking or that there is flooding. But wait a few hours or days and the puddles dry up, the leak stops and the water recedes. And then when it doesn’t rain we complain that the plants are dying and the water table is low. But wait a few days and there will be rain.   This is all brought to us by the beauty of STATES OF MATTER.

Matter, and especially water changes state every second, every minute, every hour of every day on planet Earth.

Changes in state are all about energy, specifically heat energy. If we add energy (heat) to a solid, such as ice, we get water. If we keep adding more heat, we get a gas, water vapor. To reverse the process we reduce the amount of energy and the gas becomes liquid again, and then a solid if the temperature is cold enough.

My favorite phase changes are sublimation and deposition.  It is possible to go from a solid to a gas, this is called sublimation, and from a gas to a sold, this is called deposition.  An example of sublimation is dry ice (frozen carbon dioxide). When dry ice is placed at room temperature, it changes from a solid to a gas, and skips the liquid phase. An example of deposition is the  thin film of ice that forms on window during winter months.
