So another thread on..... Mars, this time the early years of the space age

#CountdowntoMars #Mars #Perseverance

1964 was a vintage year. The Beatles, Goldfinger, (consults notes – I was very young at the time), my christening and..... oh yes, JPL sent the first missions to the Red Planet @carolynporco

What people forget is that even then so very little was known about the Red Planet as it was not easy to see with then state-of-the art equipment – in that same year of 1964 the official USAF Cartography Center map of Mars still had canals drawn on it as ridiculous as it seems

Saturn in Aquarius-Thread

Saturn will be in Aquarius until March 7, 2023.
Saturn is now in a diurnal, air, fixed domicile.
Aquarius is associated with the myth of Ganymede, the youthful cup-bearer of the Gods. This is a nuanced form of servitude; to hold that which is true

and unattainable by humanity in your cup, but to hold a juvenescence that is coveted by our lords of time.
This tension of above and below, in a diurnal sign, is far from figurative language. This dimensionality, the divide of space and time, is preferred by the essential and

inherent beingness of Saturn. This is, indeed, the geometry of time. For as where Saturn in Capricorn holds the intimacy of placing one’s feet on the ground strategically; Saturn in an air sign holds the intelligence of negative space, of borderlands, of crossing between reality

I turn to a Japanese concept of “Ma” when I think of Saturnian mastery in Aquarius, “The existence of ma in an artwork has been interpreted as "an emptiness full of possibilities, like a promise yet to be fulfilled",

and has been described as "the silence between the notes which make the music"

This is going to be a big thread about climate change, energy, and @TheExpanseWR. Literal representation, analogues, creative decisions in general - I want to talk about it all! Will post my own thoughts, other ppl's tweets, etc.

It's been in the show from day one. The opening titles of season show

- Icebergs breaking free
- The statue of liberty's little island being built up after it's coated in water
- S4,5 sea level rise in Chesapeake bay

It's in the show too. "The gulf of Denmark". Old Boston turned into the square tops of buildings barely visible. Sea walls lock out the ocean. The show is set in 2350: climate change is driving people off Earth.

Baltimore by S5 of The Expanse. Most of the "old" city is gone, flooded in by climate change.

Unlike New York, they never got their seawall up on time to protect most of the present-day city.#TheExpanse pic.twitter.com/Wt515DQBU3

Some Redditor actually found a rough comparison angle to compare the CGI future Copenhagen to the real one - I've actually walked down this bit to get the Australian consulate

Episode 2 of Season 5 has plenty of rich detail, now there are longer scenes on Earth. Baltimore is a post-climate city: a sea higher than the city itself, widespread apartment solar. Interestingly: not a single car; but a heavy, prominent (electric?) train, cycles, walking.

Just as the Sun moves through the Zodiac, medieval astrologers of the Islamic world also noted the movement of the Moon through a zodiac of its own, known as manzil al qamar or the lunar mansions.

A thread on the astrology and magic of the moon

There are 28 stations the moon travels through forming the basis of a lunar calendar used in ancient Arabia and drawn into the medieval astrology of the Islamic world.

A quick list of some of the mansions (though not all)

The first mansion is Sharatayn is of the nature of fire and is the period to take medicine and to avoid trade.

Its talismans are made to cause harm and destruction

The second mansion is Butayn of the nature of fire and is a period favorable to rulers, but less favorable for marriage.

Its talismans are made to find buried treasure and to soften the anger of kings.

The third mansion Thuraya is a good time to make requests of rulers and to travel.

Its talisman is made to grant wishes and acquire wonders and goods.

The next great conjunction of Jupiter and Saturn will be December 21, 2020. That date is, coincidentally, the date of the December solstice.

The rare occurrence will happen after sunset on Dec. 21, 2020, the start of the winter solstice.

This is a pretty valiant attempt to defend the "Feminist Glaciology" article, which says conventional wisdom is wrong, and this is a solid piece of scholarship. I'll beg to differ, because I think Jeffery, here, is confusing scholarship with "saying things that seem right".

Imagine for a moment the most obscurantist, jargon-filled, po-mo article the politically correct academy might produce. Pure SJW nonsense. Got it? Chances are you're imagining something like the infamous "Feminist Glaciology" article from a few years back.https://t.co/NRaWNREBvR pic.twitter.com/qtSFBYY80S

The article is, at heart, deeply weird, even essentialist. Here, for example, is the claim that proposing climate engineering is a "man" thing. Also a "man" thing: attempting to get distance from a topic, approaching it in a disinterested fashion.

Also a "man" thing—physical courage. (I guess, not quite: physical courage "co-constitutes" masculinist glaciology along with nationalism and colonialism.)

There's criticism of a New York Times article that talks about glaciology adventures, which makes a similar point.

At the heart of this chunk is the claim that glaciology excludes women because of a narrative of scientific objectivity and physical adventure. This is a strong claim! It's not enough to say, hey, sure, sounds good. Is it true?

So it turns out that Google Chrome was making everything on my computer slow *even when it wasn’t running*, because it installs something called Keystone which is basically malware.

I made a website because this shouldn’t

Wired first reported on how bad Keystone was 11 years ago when they put it into Google Earth (they seem to put it in all their popular

The fact that Keystone hides itself in Activity Monitor is bizarre. (The only sign of it was excessive CPU usage of WindowServer which is a system process).

I don’t know if Google was doing something nefarious with Keystone, or a third party figured out how to (which Wired warned about). But either way, I’m not inclined to give Google-the-organization the benefit of the doubt (despite the many good people who work on Chrome)...

...since it's been a decade+ and this still hasn't been "fixed".

There is no reason for auto-update software to need to do what Chrome/Keystone was doing. It also has a long history of crashing Macs.

Some quick thoughts on Sam Gyimah's resignation after conversations with various Conservative MPs: 1) the chances of a second referendum are a lot higher than I thought:

2) At this point, if you are a young and ambitious Tory MP it is now so overwhelmingly in your interest to vote against the withdrawal agreement. V v hard to see how Julian Smith can cap rebellion at under 100:

3) Really just to reiterate 1) Gyimah is the kind of "No, never gonna rebel" vaguely pro-EU Tory you'd need to get on side to outweigh Labour Leavers and Real Concerners.

So when it first appeared in Normandy, the Sherman Firefly and it's meaty 17 pounder represented an ideal combo of reliable chassis, great gun and devastating firepower right?

Ummm...

Truth is a bit more complex. /1
#WW2 #SWW #History

Deliveries of Firefly to units only commenced in April 1944,
just a few weeks before Overlord & left minimal time for familiarisation.

Armoured Regiments mostly utilised Fireflies on a basis of 1 per troop of 4 tanks. /2

Finally each armoured regiment troop had access to integral, meaty, anti-tank firepower capable of dealing serious damage to any German AFV likely to be encountered. /3

The dual purpose 75mm gun was quite capable of laying down a reasonable HE shell or AP round for dealing with Panzer III or IV.

Firefly's 17 Pounder had.... problems with HE, but excelled at tank killing. So Tigers and Panthers would need to be wary. /4

Firefly's design history dated back to March 1943 when the General Staff published "Policy on Tanks" which effectively stated the majority of tanks should have a good HE weapon and...
