M87: "Einstein's Shadow: A Black Hole, a Band of Astronomers, and the Quest to See the Unseeable" by Seth Fletcher
Einstein's Shadow: A Black Hole, a Band of Astronomers, and the Quest to See the Unseeable - Seth Fletcher

“The so-called hair-theorem maintains that they can be entirely described by three parameters: mass, angular momentum, and electric charge. They have no bumps of defects, no idiosyncrasies or imperfections – no ‘hair’.”

In “Einstein's Shadow: A Black-Hole, a Band of Astronomers, and the Quest to See the Unseeable” by Seth Fletcher

“There are actually three principles that come into conflict at a black-hole horizon: Einstein’s equivalence principle, which is the basis of general relativity; unitarity, which requires that the equations of quantum mechanics work equally well in both directions; and locality. Locality is the most commonsense notion imaginable; everything exists in some place. Yet it’s surprisingly hard to define locality with scientific rigour. A widely accepted definition is tied to the speed of light. If locality is a general condition of our universe, then the world is a bunch of particles bumping into one another, exchanging forces. Particles carry forces among particles – and nothing can travel faster than the speed of light, including force carrying-particles. But we know that locality sometimes breaks down. Entangled quantum particles, for example, would influence one another instantaneously even if they were in different galaxies. […] And after all, the whole reason black holes hide and destroy information is because of the principle of locality – nothing can travel faster than the speed of light, and therefore nothing can escape a black hole. If some sort of non-local effect could relay information from inside a black hole to the outside universe, all was well with the world.”

In “Einstein's Shadow: A Black-Hole, a Band of Astronomers, and the Quest to See the Unseeable” by Seth Fletcher

“The 20th century produced two spectacularly successfully theories of nature: general theory of relativity, and quantum theory. General relativity says the world is continuous, smoothly evolving, and fundamentally local: influences such as gravity can’t travel instantaneously. Quantum theory says the world is twitchy, probabilistic, and non-local – particles pop in and out of existence randomly and see to subtly influence one another instantly across great distances. If you’re a scientist who wants to dig down tot eh deepest level of reality, the obvious question is: which is it?”

Einstein's Peep Show by Josephine Myles 3.5 Star Review!
Einstein's Peep Show - Josephine Myles

Nerdy by day, naughty by night!

Nathan Wright has a secret life. During the day he’s a dedicated student, working hard for his maths degree. But times are tough, and in order to make ends meet by night he becomes “Einstein”, wooing punters with his online solo sex show. Still wounded by his last dysfunctional relationship, Nathan’s happy being single. But when his highest tipping client demands it, Einstein has to overcome his social awkwardness to rope in some extra help.

Party boy Rory Jones has never given his geeky neighbour a second glance, but he’s not one to turn down the offer of a free blowjob, even when Nathan tells him it’s going online. Once on camera, Rory discovers his exhibitionist streak and the two of them are so hot together, the one-off becomes a regular gig.

But being neighbours with benefits isn’t without its challenges. Nathan’s client keeps wanting more, and he finds himself pushed into a role he’s not prepared for. Meanwhile Rory’s growing affection leaves him worried his ultra-rational lover won’t ever be able to share his emotions. If he and Nathan can’t find something more than great sex in common, they’ll be left with the square root of absolute zero.




Rory and Nathan are as different as can be in this opposites attract starts like a porno frolic.

No, I don't think this "cute meet" would ever happen but once I push that aside I enjoyed the very practical Nathan and laid back Rory.

Myles sneaks in more and more emotional complexity along with the smiles and this is a satisfying read.

Smelly Socks:"Gravitational Waves - How Einstein’s Spacetime Ripples Reveal the Secrets of the Universe" by Brian Clegg
Gravitational Waves: How Einstein’s Spacetime Ripples Reveal the Secrets of the Universe - Brian Clegg

By complete coincidence, last night I had my amateur radio telescope pointed at a certain part of the sky. I had left the recording equipment on, and when I played it back this morning there was this strange message:


"Oh freddled gruntbuggly,

Thy micturations are to me

As plurdled gabbleblotchits in a lurgid bee.

Group, I implore thee, my foonting turlingdromes,


And hooptiously thrangle me with crinkly bindlewurdles,

For otherwise I will rend thee in the gobberwartswuh

With my burglecruncheon."

See if I don't!"




If you're into Physics and Smelly Socks, read on.

Einstein's Dreams
Einstein's Dreams - Alan Lightman

Not quite what I thought it was going to be, but interesting and thought-provoking nonetheless.  


My expectations were more along the lines of a fictional re-creation of Einstein's musings concerning the physics of time as depicted through his daydreams.  I was almost right.


Instead, each entry is more akin to a thought experiment, where the character Einstein draws out every idiom concerning time to it's farthest conclusion.  What would the world be like if time were frozen?  If we lived in the past?  Only for today?  Only looked ahead?


Some of the entries come closer to aspects of his theory of general relativity than others.  Some are far more philosophical than empirical.  Some had, to my way of thinking, fundamental flaws in their logic, making the entry impossible (although I attribute this to the author, not the character).   But all of them are thought provoking and each would serve as fodder for endless debates and conversations, given the right two or more people.


I'm glad I've read it, although I think Please, Mr. Einstein a far more compelling and meaningful fictional exercise.  Definitely worth a read if you're in a philosophical mood but don't want to be weighted down under anything too heavy.


This book works for the Murder Your Darlings game card: Crime Scene: the Hob, District 12.  (The cover is half black and the title is in white letters.)
