How the Hippies Saved Physics – It’s a Real Book and I Want One!

August 3, 2023 by noemi

How the Hippies Saved Physics
How the Hippies Saved Physics

Looking for a book to read? I am about to finish all of the books Orson Scott Card wrote about Ender Wiggin, and I am at a loss as to what to read next. Given that I am about to go on a week-long workation at the beach, I need a couple of books to take along for the inevitable lounging in the sun. There are ebooks, yes, but I have long since found out that electronics and the scorching sun are not friends.

Anyhow, in my quest to look for something new to read, I came across a relatively new book titled “How the Hippies Saved Physics: Science, Counterculture, and the Quantum Revival. I have to admit that while I did rather well in physics in school, the applied aspect seems to elude me more these days. Then again, that’s what books are for, right? Given the title alone, I am willing to bet that this book will be an entertaining read – at the very least.

Written by David Kaiser, the book is all about physicists in the 1970s, when the world was experiencing one of the most unique periods in history. Apparently, during the time of free love and anti-war protests, the world of physics was in a rut. In spite of the prevailing idea of conformity (I guess in the physics world), a group of physicists in Berkeley, California (where else?) decided to go against the flow. They named their group “Fundamental Fysiks Group” and approached physics in a whole new way. Applying ideas from Eastern mysticism and psychic mind-reading, these guys have influenced modern physics. Believe it or not, some of them even took LSD to tap into their wells of creativity even more. Funnily enough, thinking back, I can easily see my college physics professor being part of this group.

Keeping true to the creative spirit that fueled that group several decades ago, the book includes 46 black and white illustrations – maybe in case you don’t like books with too many words. 😉

The hardcover version is available on Amazon for $16.22. I doubt I’ll be able to get my hands on this before the weekend, but if any of you do read it, share your thoughts?

Duct Tape Wave Machine

July 24, 2023 by noemi

What do you do when you have a lot of spare time, a lot of duct tape, some shish kabob skewers, and rubber stoppers for Erlenmeyer flasks? ((Refresh your memory: an Erlenmeyer flask is a piece of equipment used in the lab. It is characterized by a flat bottom, a conical body, and a cylindrical neck.)) Well, if you’re YouTube user RDSQC, you will make your own wave machine, take a video of it in action, and upload it for the entire world to see!

As you can see, this is not the wave machine that you use to make waves in pool to simulate the ocean’s movement. (Duh.) If I am right, this is actually a DIY version of a Shive wave machine, which was named after Dr. John Shive. He developed the machine back in the 1950s when he was working at Bell Labs.

So what’s the point in having a machine like this? (Aside from the fact that the guys look like they were having fun making the machine move.)

The purpose of a Shive wave machine is supposed to demonstrate how slow transverse waves move. In order to make this machine, the rods (shish kabob sticks in this case) have to be placed at regular intervals. In conventional wave machines, the rods are attached to a wire spine. In a MacGyver-worthy move, this DIY-er decided to use duct tape.

I don’t know what practical use the average person will ever have for one of these machines, but RDSQC, MacGyver would be so proud of you! ((Source: RDSQC))

Now if you happen to adore physics, you can see videos of “real” wave machines here.
