How The Hippies Saved Physics, Science, Counterculture, and the Quantum Revival by David Kaiser



How The Hippies Saved Physics, Science, Counterculture, and the Quantum Revival by David Kaiser

David Kaiser is a professor at Massachusetts Institute of Technology.  This book is a history of science book.  It is also a popular science book. The book describes how quantum physics which many considered to be fringe science became accepted science.  It is a very strange, eccentric, and interesting story.


The book focuses on a group called the Fundamental Fysiks Group which held sessions at the University of California Berkeley.  Berkeley California is known for its eccentricity and counterculture.  The Fundamental Fysiks Group was instrumental in making quantum mechanics acceptable science.

The cast of characters in this book is very different; Jack Sarfatti, Paul Sirag, and Nick Herbert are the central people covered.  There is also quite a bit in the early chapters on Werner Heisenberg, Albert Einstein, and Erwin Schrodinger.  There are also numerous scientists spread throughout the book including Richard Feynman and Fritjof Capra who wrote The Dancing Wu Li Masters.

The story is very eccentric and outright strange to the point where it is funny.  There are very surprising sources of funding for the experiments which helped establish quantum physics.  There is the Esalen institute a New Age retreat in California, Werner Erhard and Est who were part of the human potential movement,  Henry Dakin the philanthropist and supporter of paranormal research, and the CIA with its remote viewing experiments.

The experiments themselves are very interesting to read about. They prove things like quantum encryption, nonlocality, and entanglement.  Some experiments do not succeed like faster than light communication.

This is a fascinating history about a very unusual topic which most people have a difficult time understanding.  It shows a process where fringe science is made into accepted science.

The book is very easy to read.  It mostly focuses on the people behind the story, not the physics.  The writing is very clear. There is an index, extensive notes, and bibliography.  There are numerous black and white photographs and easy to understand diagrams.  I found it to be a delightful book to read.

Awesome Ways Movies Predicted Future Technology

The future has arrived... and it looks oddly like an eighties film. Despite the fact that a quarter of a century after Back To The Future, we still do not have hoverboards, flying cars, or cold fusion, a lot of modern ingenuity has yielded results that look, well, pretty much like the movies we grew up with.

Here a few of the more brilliant future predictions from films of previous decades.

The Roomba

Predicted by: Star Wars, The Fifth Element

Oh, the mind-blowing, fantasy-inducing concept of sitting back with a cold one while a robot cleans your kitchen for you! When Zorg leans back in his chair and ruminates on the beauty of his robotic cleaning appliances, it's hard to disagree. Also hard to disagree with is the sort of elephant worm-baby he keeps as a pet.

It has HUMAN EYES!!

Elephant aside, it seems we didn't need to wait until the year 2263 for some tech geeks to put the ultimate human fantasy into motion. Product: the Roomba. A freaking robot that cleans your freakin' house, while you sit back with a cold one.

Guaranteed not to overthrow the universe.

Robotic Limbs

Predicted by: Star Wars, Cyborg, The Six Million Dollar Man

Recent advances in prosthetics have yielded replacement limbs so cool as to almost take the sting out of losing a limb in the first place.

A good sense of humour can also go a long way towards this end.

But seriously, behold the beauty that is the myoelectric limb:

These nifty devices operate using myoelectrography - that is, sensors attached to the remaining limb interpret output from voluntary muscle movements. You might not have a forearm anymore, but you have muscles in your upper arm that would have controlled its movements. The prosthesis extrapolates what your forearm or hand would be doing when those muscles are moved, and moves the prosthesis accordingly. The most recent models allow complex movements of the fingers and thumb, allowing for rotation and adjustment of grip, giving users a fairly good approximation of normal hand movement.

You can even get a fancy cover for these prosthetics, called a cosmesis, which approximates the appearance of normal human skin. Copy and paste the link below for some great images of just how realistic this can look, as well as an enthusiastic testimonial from a user.

Neural Prostheses

Predicted by: Johnny Mnemonic, The Matrix

Ok, it doesn't really look like that. It looks much more like this:

Pictured: Less frightening


Fortunately, the 90's shocker that was "Johnny Mnemonic" predicted the technology but not the application. Rather than nefarious purposes such as information-smuggling, modern medicine employs these implants for things made of sheer awesome, such an enabling deaf people to hear again. Oh, and speaking of sheer awesome, did I mention that these devices are basically computer chips that are configured to fit into and work with your brain, replacing damaged or impaired neural networks?

With these types of advances, it's only a matter of time before we can download Ju-Jitsu straight into our skulls.

And, presumably, stop bullets while looking like a stone-cold douchebag.


Androids

Predicted by: Blade Runner, Alien


The Japanese android or "actroid" DER-01 contains 47 moveable joints, and is capable not only capable of performing complex hand and foot movements, but mimicking a range of facial expressions.

In a really non-convincing way.

Potential uses for this type of android have not been clearly articulated - they don't really need to be, as most tech-geeks are happy enough just to stare at the thing in wonder, and ruminate on how much it might cost to buy one. My personal prediction is that they end up somewhere between interpreter droids and sexbots:

We are already frightening close on this score.

Any others?
