Cornel West and Gravitational Waves: Blues and Coalescence

Yesterday, two exciting things happened. Scientists announced at a press conference that something predicted by Albert Einstein — a gravitational wave — was detected. And the same day, I heard Cornel West speak to a packed auditorium at Smith College.

On first glance, these might seem entirely unrelated, except for the fact that they both occurred on the same day. There was another similarity, however: both the scientists who detected a gravitational wave and Cornel West used the same word to describe a profound concept. That word is “coalescence.”

Coalescence is the name for what happens when two or more separate things come together to form one thing.

Gravitational waves can be detected when two massive systems, like two black holes, come together. As they approve, they spin faster and faster, “much like a spinning figure skater who draws his or her arms in close to their body.” Source: LIGO Scientific Collaboration. The frequency of the waves thereby increases until the moment of coalescence, when the two black holes come together as one.

Dr. West used “coalescence” to describe people coming together, realizing their connectedness. And wow, did he connect people. As soon as Dr. Cornel West entered the room, people rose from their seats, giving him a standing ovation. I am embarrassed to admit it, but I said,

“Why are people standing up? He hasn’t even said anything yet.” Which was patently false, and it was a very silly and thoughtless thing to say. Of course Dr. Cornel West had said something already. That’s why he was invited to speak. People knew him because he had said something. Something real and important. And now he was going to speak again.

I have been to one other event I can remember where people gave a standing ovation upon the entrance of the speaker to the stage. The other time was a concert by Yo Yo Ma, who is one of my favorite musicians, and I eagerly jumped up to applaud upon his entry.

After listening to him speak, I understand now why people applauded when Dr. Cornel West walked into the room. He has presence. And he acknowledges people gracefully — it’s clear why he is a respected leader. Dr. West accepted the introductions given to him by two Smith students by giving them a big embrace. He gave thanks to his colleagues doing good work at Smith and Holyoke. He also acknowledged that any of the good he does is only possible because he was loved. Beyond being gracious, Dr. West spoke passionately about injustices present in today’s society. Acknowledging how radical counter-cultural it is given such an environment, he urged the audience to become love warriors.

Throughout his speech, Dr. West dropped names right and left, but he did so in such an invested and appreciative way — both for those he agreed with and those he disagreed with and affectionately imitated or parodied — that I very much enjoyed his lists and associations. He spoke of Ferguson. He spoke of politicians Bernie Sanders and Hilary Clinton. He spoke of feminist Gloria Steinem and poet Sylvia Plath. He spoke of philosophers Socrates and Aristotle. He spoke of writer Franz Kafka.

To my surprise, Dr. West spoke less about politicians than about “blues people:” people who sing sweetly against a backdrop of darkness of which they are painfully and thrillingly conscious. Aretha Franklin, Bob Dylan, Coltrane, and others.

He spoke also of a woman who had lost her son to violence at the hands of white supremacists, who threw his body in a river after they had killed him. She dragged out the body, and brought the open casket to church. The head swollen three times its normal size. When she was told to close the casket, she refused, saying that people needed to see the underbelly of our society. Dr. West pointed out that this courageous woman is the tip of the iceberg. She is one of many invisible and anonymous brave people who are standing up to speak despite powerful interests telling them to shut up. We need to listen if we are ever going to make real peace. Making peace requires love warriors.

Currently, the seamy dark underbelly of our society is all too large. Racial injustice. Social and environmental injustice. Flint, Michigan. Birth defects in the families of veterans after the spraying of Agent Orange during the Vietnam War (Source: U.S. Department of Veteran Affairs). Think of the Vietnamese civilians who were not just exposed to the chemicals, but whose lands and drinking water were directly sprayed and contaminated. Think of the concentrations they were exposed to. We need to shed light on the effect our military has on other human beings. We need to be conscious of and be honest about where our infrastructure is failing the people who are trusting it to be safe for their health. We need to listen to people’s suffering so that we can be conscious and ethical and retain our humanity — the music, the sharing, the spark that connects us and gives meaning to our lives. We need to listen so we can coalesce into an undivided society, for liberty and justice for all. We’ve said “All lives matter” for a long time without it registering. Of course all lives matter. We said “all lives matter” when full-fledged slavery was active in this country. That’s why we still need to remind our country specifically, “Black lives matter.”

 

Playing with Animation

Students of any age, elementary school age to adult, can learn to program and animate using Khan Academy. Here’s a simple “spin-off” project, one that I made using some pre-existing code and running with Khan Academy’s hints and suggestions. Scroll down to see the blue box in the righthand column below where you can click your mouse to randomly generate a fish.

The Delight of Corner Reflectors

erik

Corner reflectors are amazing.

They help cars see you (sometimes) on your bike at night.

There’s one on the moon that reflects back laser light.

They’re in the channel to help boats see

Obliging across the spectrum, corner reflectors be.

Here’s a great video about corner reflectors on the moon, which also talks about how corner reflectors work, and offers entertaining digressions like how astronauts deal with their poop.

Lesson Plan: A good lesson for students (perhaps Fifth or Sixth Grade, or even Seventh Grade, Eighth Grade, or older) would be to watch this video and make corner reflectors of their own using this science “snack” from the Exploratorium. The Exploratorium website is a wonderful resource for science teachers.

What is a Science Snack, anyway?
An Exploratorium Snack is a hands-on science activity. Science Snacks are tabletop exhibits or explorations of natural phenomena that teachers or students can make using common, inexpensive, readily available materials.

Science Snacks are divided into easy-to-follow sections that include instructions, advice, and helpful hints. Each one begins with a photo and/or video, a short introduction, and a list of materials. Other sections include assembly instructions, how to use the activity, and explain what’s going on, science-wise. Most Science Snacks can be built by one person; we indicate if a partner or adult help is needed, this is indicated. A section called “Going Further” offers interesting bits of additional scientific and historic information.

Why are they called Snacks rather than activities?
The Exploratorium is a science museum with hundreds of hands-on exhibits. Early in our history, other museums would ask for “recipes” to build and duplicate these exhibits, so we published a series of books called the Exploratorium Cookbooks. Teachers wanted to build classroom-sized, less expensive versions of these same exhibits, so we created Science Snacks as a way to bring our exhibits into the classroom. We published these in a book called The Exploratorium Science Snackbook.
Many of the original Snacks we built were based on museum exhibits. We’ve since branched out to cover content that spans science curriculum for grades 6-12.

If you’re interested in learning about the channel markers like the can buoy pictured up top, you can click here. The buoy is green, and has the #5, an odd number, so you know that it’s a buoy that marks the right side of the channel when leaving the harbor.

If you’re a squash player, you might already exploit the corners of the court to send a ball right back where it came from.
