Tales of the Second Boston Tea Party?

Boston’s first tea crisis lasted two months. The town heard about East India Company tea coming to certain merchants by 18 October, when the Boston Gazette published the news. The men and boys who destroyed that tea headed home late at night on...

A flawed survey of science and the occult in the Early Modern Period

There is no shortage of good literature on the relationships between science and magic, or science and astrology, or science and alchemy during the Early Modern Period so what is new in Mark A. Waddell’s Magic, Science, and Religion in Early Modern...

Christmas Trilogy 2020 Part 3: The peregrinations of Johannes K

We know that human beings have been traversing vast distances on the surface of the globe since Homo sapiens first emerged from Africa. However, in medieval Europe it would not have been uncommon for somebody born into a poor family never in their life...

The solar year ends and starts with a great conjunction

Today is the winter solstice, which as I have explained on various occasions, in the past, is for me the natural New Year’s Eve/New Year’s Day rather than the arbitrary 31 December/1 January. Obligatory Stonehenge winter solstice image Today...

The emergence of modern astronomy – a complex mosaic: Part LI

  By the middle of the nineteenth century there was no doubt that the Earth rotated on its own axis, but there was still no direct empirical evidence that it did so. There was the indirect evidence provided by the Newton-Huygens theory of the shape...

Illuminating medieval science

  There is a widespread popular vision of the Middle ages, as some sort of black hole of filth, disease, ignorance, brutality, witchcraft and blind devotion to religion. This fairly-tale version of history is actively propagated by authors of popular...

The emergence of modern astronomy – a complex mosaic: Part L

By the end of the eighteenth century, Newton’s version of the heliocentric theory was firmly established as the accepted model of the solar system. Whilst not yet totally accurate, a reasonable figure for the distance between the Earth and the Sun,...

The emergence of modern astronomy – a complex mosaic: Part XLIX

By the middle of the eighteenth century, Newton’s version of the heliocentric theory had been universally accepted by all of those knowledgeable enough to express a considered opinion on the subject. However, some (most?) Jesuit astronomers continued...

The emergence of modern astronomy – a complex mosaic: Part XLVIII

The model of the solar system that Johannes Kepler presented in his mature work had dimension significantly larger than any of the other geocentric, heliocentric, or geo-heliocentric systems on offer in the early part of the seventeenth century. Although...

“A sea of wild, woolly thinking!”

Today’s musings on the history of science re-examine a topic that I have already dealt with several times in the past, that of presentist judgements on the heuristic used by a historical figure to find or reach their solution to a given scientific...

The emergence of modern astronomy – a complex mosaic: Part XLVII

One aspect central to the astronomical-cosmological discourse since antiquity was the actual size of the cosmos. This became particularly relevant to the astronomical system debate following Tycho’s star size argument. He argued given his failure...

Video-menu launched on the Marius-Portal

Regular readers of this blog will know that I am part of a group of historians of astronomy, who have, since 2014, been involved in restoring the reputation of the Franconian astronomer Simon Marius (1573-1624) . Simon Marius Source: Wikimedia Commons...

The emergence of modern astronomy – a complex mosaic: Part XLVI

The discovery of stellar aberration was empirical evidence that the Earth orbits the Sun; finding empirical evidence that the Earth rotates daily on its axis proved, perhaps surprisingly, difficult. The first indirect evidence for diurnal rotation in...

Astrology in the age of Newton

My Annus Mythologicus blog post was recently retweeted on Twitter in response to an inane tweet from Richard Dawkins and somebody questioned the reference in it that Newton was inspired to take up mathematics upon reading a book on astrology. This was...

The emergence of modern astronomy – a complex mosaic: Part XLV

The problem of an empirical proof of heliocentricity would occupy astronomers for the next couple of centuries following the publication of Newton’s Principia; the general acceptance of heliocentricity had now been achieved, but people very much...

The emergence of modern astronomy – a complex mosaic: Part XLIV

Whilst the European community mathematicians and physicist, i.e. those who could comprehend and understand it, were more than prepared to acknowledge Newton’s Principia as a mathematical masterpiece, many of them could not accept some of the very...

Notes on Post Tags Search

By default, this searches for any categories containing your search term: eg, Tudor will also find Tudors, Tudor History, etc. Check the 'exact' box to restrict searching to categories exactly matching your search. All searches are case-insensitive.

This is a search for tags/categories assigned to blog posts by their authors. The terminology used for post tags varies across different blog platforms, but WordPress tags and categories, Blogspot labels, and Tumblr tags are all included.

This search feature has a number of purposes:

1. to give site users improved access to the content EMC has been aggregating since August 2012, so they can look for bloggers posting on topics they're interested in, explore what's happening in the early modern blogosphere, and so on.

2. to facilitate and encourage the proactive use of post categories/tags by groups of bloggers with shared interests. All searches can be bookmarked for reference, making it possible to create useful resources of blogging about specific news, topics, conferences, etc, in a similar fashion to Twitter hashtags. Bloggers could agree on a shared tag for posts, or an event organiser could announce one in advance, as is often done with Twitter hashtags.

Caveats and Work in Progress

This does not search post content, and it will not find any informal keywords/hashtags within the body of posts.

If EMC doesn't find any <category> tags for a post in the RSS feed it is classified as uncategorized. These and any <category> 'uncategorized' from the feed are omitted from search results. (It should always be borne in mind that some bloggers never use any kind of category or tag at all.)

This will not be a 'real time' search, although EMC updates content every few hours so it's never very far behind events.

The search is at present quite basic and limited. I plan to add a number of more sophisticated features in the future including the ability to filter by blog tags and by dates. I may also introduce RSS feeds for search queries at some point.

Constructing Search Query URLs

If you'd like to use an event tag, it's possible to work out in advance what the URL will be, without needing to visit EMC and run the search manually (though you might be advised to check it works!). But you'll need to use URL encoding as appropriate for any spaces or punctuation in the tag (so it might be a good idea to avoid them).

This is the basic structure:

http://emc.historycarnival.org/searchcat?s={search term or phrase}

For example, the URL for a simple search for categories containing London:

http://emc.historycarnival.org/searchcat?s=london

The URL for a search for the exact category Gunpowder Plot:

http://emc.historycarnival.org/searchcat?s=Gunpowder%20Plot&exact=on

In this more complex URL, %20 is the URL encoding for a space between words and &exact=on adds the exact category requirement.

I'll do my best to ensure that the basic URL construction (searchcat?s=...) is stable and persistent as long as the site is around.
