Too good to be true?

Extra Sensory: The Science and Pseudoscience of Telepathy and Other Powers of the Mind

Brian Clegg
Non-fiction, 321 pages

If you’re looking for proof of psi phenomena you won’t find it here. Instead, you’ll read a history of poorly designed research and questionable results. This is interesting in itself as an explanation of what constitutes good experimental design and what doesn’t. Although the author describes several theoretical mechanisms that could explain psi phenomena, he also notes that only minimal evidence supports its existence.

 In his conclusion, Brian Clegg notes, “… coming at this with an open mind while frankly wishing that ESP did exist, I have to conclude that the existing experiments have demonstrated nothing more than coincidence, artifacts of the experimental design, misunderstanding, and fraud.”

 Another physicist, Wolfgang Pauli, became a good friend of psychiatrist, C. G. Jung. The two collaborated together on a book with each contributing a section. In Jung’s section, the psychiatrist describes what he calls synchronicity, a phenomena consisting of meaningful coincidences, and considered to be an acausal connecting principal. Pauli himself experienced a type of synchronicity as the jocularly known Pauli Effect. Reputedly equipment malfunctioned whenever Pauli entered a laboratory in response to the Pauli effect. Jung’s synchronicity as well as Pauli’s Effect is largely based on anecdotal evidence and not achievable in a laboratory as a significant percent of correct guesses regarding the next cards in a deck.

Clegg feels that current methods of testing psi phenomena will never produce significant results. “What the researchers seem to have totally forgotten is that they are attempting to verify the validity of hundreds of years of anecdotal evidence. … Real-world ESP is not about small statistical variations; it is about clear, specific communication.”

The bloodshed must stop

"Adieu!" she said softly.
And I put a bullet in the calf of her leg. She sat down—plump! Utter surprise stretched her white face. It was too soon for pain. I had never shot a woman before. I felt queer about it.
"You ought to have known I'd do it!" My voice sounded harsh and savage and like a stranger's in my ears. "Didn't I steal a crutch from a cripple?"
 
Rather than allow her escape, Dashiell Hammett’s detective shoots his suspect. Although firing on non-threatening fleeing suspects is illegal, it doesn’t stop the Continental Op. It doesn’t stop some police officers either. Hammett’s operative experiences moral uncertainty before putting one bullet in a non-lethal spot. I wonder what Rusten Sheskey experienced as he put seven bullets in Jacob Blake’s back while fellow officers watched. I think he used excessive force. Kenosha County District Attorney, Michael Graveley, doesn’t share my opinion. He declined to bring charges against Officer Sheskey.

A few miles from where Derek Chauvin stands trial for George Floyd’s death, a female officer killed yet another, non-threatening, fleeing suspect. She didn’t kneel on his neck for over nine minutes as did Derek Chauvin. Instead she mistook her gun for a taser. Answering your question is police use-of-force expert, Ed Obayashi, summarized in the New York Times, "… the officer can become accustomed to using the same hand to draw either weapon, a habit that can make it harder to tell one from the other in high-pressure situations when muscle memory and instinct kick in."

Okay, that makes sense, but why didn’t she simply let him drive home and arrest him later. I’ve noticed, in some of these recent police killings, the blameworthy officer had an audience, in several cases, rookies. Does that matter or is it coincidence?

A second’s worth of poor video shows 13 year old, Adam Toledo, unarmed, and with hands raised, just before being fatally struck by a bullet. Neuroscience shows that actions can be decided and implemented half a second before they become conscious. The officer made a split-second decision that turned out wrong. Was he wrong?

Yes, according to the Lone Ranger. “I'll shoot to wound, not to kill. A man must die, it's up to the Lord to decide that; not the person behind the six shooter.”

The Lone Ranger had a steady hand and rawhide nerves. He would not have shot Adam Toledo. Only if Adam were armed would the Lone Ranger have fired a wounding shot.

In an ideal world, police would act more like cowboys or Dashiell Hammett detectives. Sam Spade occasionally disarmed bad guys, but he didn’t carry a gun himself. “Yeah, right. What about racist policing?” you ask.

Well, according to the fifth principal of Gene Autry’s Cowboy Code, a cowboy, “must not advocate or possess racially or religiously intolerant ideas.”

At this point you’re thinking I’m talking nonsense You want to remind me that cowboys and movie detectives are make-believe. Yes, I’ll agree, I am talking nonsense. For this I blame the ancient Greeks and Romans. They endowed humans with a rationality that humans don’t always display. In a tense situation, rational responses are less likely to occur than those triggered by reflexes. Perhaps unconscious racism sometimes kicks-in as well.

We need more fool-proof policing methods. For example, instead of having a pistol shape, tasers could be shaped like dildos. I don’t think a cop could mistake a gun for a dildo. Better yet, let’s do away with tasers entirely. Sometimes they fail to subdue suspects, enraging them instead. There must be better mousetraps we can invent.

Lastly, there are many situations that can end peacefully if approached peacefully. Paladin’s calling card read, “Have Gun Will Travel,” but he rarely used his six shooter. He preferred conflict resolution to gunplay. According to Vox, police recruits receive extensive firearms training, but little training in conflict management. It’s time for serious changes in our policing philosophy and methods. The bloodshed must stop.

Gravity. Bet you fall for it too

Gravity: How the Weakest Force in the Universe Shaped Our Lives

Brian Clegg
Non-fiction, 335 pages

Books like this don’t have happy endings. In fact, they don’t have proper endings at all. They begin with questions and end with even more questions. I like to read them anyway.

Clegg begins with history: What were the earliest notions of gravity and how did they evolve? When people think of gravity they often think of Isaac Newton, but the idea of gravity had precedents in ancient Greek thought. Later, Copernicus, Kepler, Galileo and others elaborated on the ideas that later influenced Newton. Then in the twentieth century, Albert Einstein introduced an entirely new framework for understanding gravity.

 About the time Einstein was tackling gravity, other scientists were developing quantum physics. Now a new problem arose. Einstein’s gravity is very good at explaining the behavior of large objects like stars and planets, while quantum physics can account for the behavior of small objects like atoms and particles. However, the two theories don’t play well with each other.

 In the latter half of the twentieth century string theory was developed as a means of unifying the two theories. String theory, however, introduces a number of unanswerable questions.  Clegg discusses several newer theories that may help resolve the problems of string theory. One of these was inspired by graphene, a one atom thick layer of graphite. When graphene is cooled to an extreme temperature, it appears to violate the rules of special relativity. Peter Horava wondered about the implications of this finding. Einstein gave us the concept of space-time. Horava’s theory breaks space and time apart again. By doing so, he is able to make general relativity and quantum physics work together.

 All of the recently emerging theories will require further research. Gravity, the weakest of the four forces, has remained elusive. Gravitons have been hypothesized, yet never found.
