Some History of technology

Where it began, for our purposes, little known Elizabethan physician Gilbert

Stephen Gray, the discoverer of electrical conduction

Thought Morse invented the Telegraph? Francis Ronalds invented it in 1816. Unfortunately no-one wanted it.

More on early telegraphs

It has been 150 years since Maxwell presented his equations:

The history of Maxwells equations

My friend has summarised them here:

Maxwells Equ

🆕The origin of Maxwells equations and Gauge theory, Faraday is the hero.

Heaviside’s conflict with Preece “Theory versus practice”


A worthy biography of Heaviside is “Oliver Heaviside”   by Paul Nahin

Another book on Heaviside

Another 150th anniversary George Boole. Boole like Heaviside was self -taught.

There is more to Boole than Boolean

Interesting article about a contemporary of Maxwell and Boole, namely Babbage

More detail on the invention

Article about Babbages friend, the first programmer, Ada–augusta-ada-lovelace/id/7225

Great piece on Ada and Babbage by Wolfram

Impressive comic book of the Ada/Babbage story

Another contemporary British invention, the Bessemer process

A quartet of Victorian engineers beginning with B

I had to make it a quintet of people beginning with B. Thomas Bayes came up with Bayes’ Theorem, a basic law of probability governing how to modify one’s beliefs when new evidence arrives. Are you Bayesian or Boolean?

In the Boolean worldview, the world is organised into basic situations such as Sydney being north of Melbourne. Such situations are facts. Truth is correspondence to facts. That is, if a belief matches a fact, it is objectively true; if not, it is objectively false. If you and I disagree, one of us must be right, the other wrong; and if I know I’m right, then I know you’re wrong. Totally wrong.

In the Bayesian worldview, beliefs are not simply true or false, but more or less probable. That is, we can be more or less confident that they are true, given how they relate to our other beliefs and how confident we are in them. If you and I disagree about the cause of climate change, it is not a matter of me being wholly right and you being wholly wrong, but about the differing levels of confidence we have in a range of hypotheses. Dare I say it, shades of grey!

Good explantion of Bayes Theorem

Another question, are you Babylonian or Balkan in your Philosophy? Feynman used to say that there were two kinds of Physicists, the Babylonians and the Greeks. He was referring to the opposing philosophies of those ancient civilizations. The Babylonians made western civilization’s first great strides in understanding numbers and equations, and in geometry.
Yet it was the later Greeks – in particular Thales, Pythagoras, and Euclid – whom we credit with inventing Mathematics. This is because the Babylonians cared only whether or not a method of calculation worked – that is, adequately described a real physical situation – and not whether it was exact, or fitted into any greater logical system. Thales and his Greek followers, on the other hand, invented the idea of theorem and proof – and required that for a statement to be considered thorough, it had to be an exact logical consequence of a system of explicitly stated axioms or assumptions. To put it simply, the Babylonians focused on phenomena, the Greeks on the underlying order.”
Nevertheless, the existence of Babylonian method has actually a deep sense: axiomatic approach can be formulated only if satisfactory number of facts, needed for the generalization, is accumulated.
