Batteries électriques - by Alexander Volta

In 1800 the Royal Society published Alexander Volta's description of how he built his batteries.

It is not widely known that Volta invented both the 'wet' and the 'dry' battery.  Most writers mention Volta's pile - a 'dry' battery, but omit to mention his 'crown of cups', or 'wet' battery.

Strange, the EU was aware of the NSA (spying) global gathering of electronic data since 2001.  Sorry folks, this is not news.  I wrote about this several years ago in this forum under the title: Quantum Physics; Humor, Sensationalizing, Hard Science, Espionage

Part of this post is quoted below.

"Espionage-

In A. D. 1300 in Poland, more precisely in the region of Kashubia, was coined the term "nachzehrer" to define the female vampire, or "chewing the shroud" or "devourer of the night." 

The Nachzehrer would be a special kind of vampire who lives in a constant state of numbness in his grave, without understanding what is happening around and just like a child, chewing spasmodically his dress.

Most people, including many scientists and electrical engineers, have never heard of Wilhelm Josef Sinsteden.  He invented the lead-acid battery and published his findings in 1854.  In 1860 an improved construction by Gaston Raimond Planté was the first commercially viable version.  It is probably the wide marketing and adoption of the Planté cell which has led to so many books and articles - even a majority of scientific papers - stating that Planté invented the first of these batteries, usually giving 1859 as the date. 

Legendary Confederate fighter Thomas J. "Stonewall" Jackson died 150 years ago but the actual cause of his death has been a subject of debate. And it was again at the 20th annual Historical Clinicopathological Conference in Maryland.

Jackson got the nickname "Stonewall" from Confederate General Barnard E. Bee, when he moved an artillery battery up to support Bee's troops as they retreated at the First Battle of Bull Run (called First Manassas by Confederate troops)(1). Bee said of the mostly unheralded Colonel, "There is Jackson standing like a stone wall. Let us determine to die here, and we will conquer. Rally behind the Virginians."
Richard Holmes - Falling Upwards

Falling Upwards.  What a wonderful title for a history of ballooning.

As someone with more than a slight interest in the history of science and technology*, I intend to buy a copy of this new book.

Falling Upwards is a wonderful history of the early years of ballooning, crammed with adventures and musings. Beginning in the 1780s with the generation that thought travel would be revolutionised by the balloon, it finishes at the end of the 19th century, when ballooning appealed only to those wanting something “refreshingly unreliable: a means to mysterious adventure rather than a mode of mundane travel”.

The news that Neil Armstrong's EKG is up for auction has been reported across the world.  Having more than a passing interest in how language is used, I was looking at the different ways that writers have dealt with this story when the article by PC mag caught my eye.  The image they posted was not the same as the one from RR Auction.

I recently posted an article: Neil Armstrong's Heartbeat - EKG Up For Auction.  Unsurprisingly many other news sources have featured the same story, after all, this is a unique item.
British Radar in WW2 -  by Sir Robert Watson-Watt

I am pleased to be able to publish here in my blog a historical document of some importance: a short history of radar by Sir Robert Watson-Watt.  The document - reproduced below these introductory comments - includes some information and images which have not, to the best of my knowledge, been published before on the internet.  Of special interest to historians is the

first photographic record of radiolocation of aircraft, made on the 24th of July, 1935.
