The Industrial Revolution transformed and shaped our modern world as we know it. Why did the fundamental changes of the Industrial Revolution begin in Great Britain? In our first episode about the era of Industrial Revolution, Brett explains how the agricultural revolution, a few inventions in the textile industry, the steam machine, improving means of transport and an overall changing society created a solid basis for the coming changes of the late 18th century.

David Fletcher’s Tank Chats #1: The A13 Cruiser
Published on 13 Feb 2015
The first in a series of short films about some of the vehicles in our collection presented by The Tank Museum’s historian David Fletcher MBE.
The A13 was the first British tank to have Christie Suspension. With a top speed of 40 miles per hour, it was much faster than the German Panzers, and had one of the best guns of its time. Despite this, many were lost in the battle for France in 1940. They fared better in the desert when their speed enabled them to cut off and defeat a huge Italian Army at Beda Fomm in Libya.

“Apollo 8 altered the self-perception of our species forever”
Colby Cosh contrasts the insane bravado of John F. Kennedy’s moonshot announcement with the more recent insane bravado of Elon Musk and SpaceX:
SpaceX, the private rocketry company founded in 2002 by billionaire adventurer Elon Musk, says it is developing plans to fly two unnamed persons to the moon late in 2018. This announcement has created both skepticism and alarm. This is, I think, partly a matter of confusion about prepositions.
If I announced that, despite being Canada’s most sedentary citizen, I was going to Mount Everest next week, you would probably know better than to assume I was going UP the mountain. SpaceX’s proposal is to send a manned spacecraft beyond the moon. That’s the word they use in the SpaceX press release, and whoever chose it should get a big fat bonus. “Beyond” is an English word of unparalleled connotative power and romance.
But, of course, going beyond the moon — more prosaically, looping around it and coming back — is much, much simpler than landing ON it. It is probably not a fantastically difficult challenge, and the company’s zany-sounding timeline may be justified. (Mind you, this is not a prediction.)
Even if you are old enough to have followed the golden age of spaceflight as it happened, you may not understand or remember the half-insane ambition of John F. Kennedy’s original proposal to land men on the moon. For young and old, the moment that the Apollo 11 lunar module landed on the Sea of Tranquility tends to obscure everything else about the tale in retrospect. But no U.S. astronaut had orbited the Earth yet when JFK threw down the gauntlet. No spaceship had photographed, much less touched, the moon.
Taken by Apollo 8 crew member Bill Anders on December 24, 1968, at mission time 075:49:07 (16:40 UTC), while in orbit around the Moon, showing the Earth rising for the third time above the lunar horizon. The lunar horizon is approximately 780 kilometers from the spacecraft. Width of the photographed area at the lunar horizon is about 175 kilometers. The land mass visible just above the terminator line is west Africa. Note that this phenomenon is only visible to an observer in motion relative to the lunar surface. Because of the Moon’s synchronous rotation relative to the Earth (i.e., the same side of the Moon is always facing Earth), the Earth appears to be stationary (measured in anything less than a geological timescale) in the lunar “sky”. In order to observe the effect of Earth rising or setting over the Moon’s horizon, an observer must travel towards or away from the point on the lunar surface where the Earth is most directly overhead (centred in the sky). Otherwise, the Earth’s apparent motion/visible change will be limited to: 1. Growing larger/smaller as the orbital distance between the two bodies changes. 2. Slight apparent movement of the Earth due to the eccenticity of the Moon’s orbit, the effect being called libration. 3. Rotation of the Earth (the Moon’s rotation is synchronous relative to the Earth, the Earth’s rotation is not synchronous relative to the Moon). 4. Atmospheric & surface changes on Earth (i.e.: weather patterns, changing seasons, etc.).

Possible end-game for the British nuclear deterrent
Charles Stross speculates on a few ways that Il Donalduce could trigger the end of Britain’s nuclear-armed ballistic missile submarines:
Working hypothesis #1: Donald Trump is an agent of influence of Moscow. Less alarmingly: Putin’s people have got blackmail material on the current President and this explains his willingness to pursue policies favourable to the Kremlin. Russian foreign policy is no longer ideologically dominated by communism, but focusses on narrow Russian interests as a regional hegemonic power and primary oil and gas exporter.
Clearly, it is not in Russia’s geopolitical interest to allow a small, belligerent neighbor to point strategic nuclear missiles at Moscow. But this neighbor’s nuclear capability has a single point of failure in the shape of the resupply arrangements under the 1958 UK-USA Agreement. Donald Trump has made no bones about his willingness to renegotiate existing treaties in the USA’s favor, and has indicated that he wants to modernise and expand the US strategic nuclear capability. Existing nuclear weapons modernization programs make the first goal pointless (thanks, Obama!) but he might plausibly try to withdraw British access to Trident D-5 in order to justify commissioning four new US Navy SSBNs to carry the same missiles and warheads.
(Yes, this would break the “special relationship” between the USA and the UK for good — but remember, this is Donald Trump we’re talking about: the original diplomatic bull in a china shop who decapitated the state department in his first month in office.)
Trump could present this as delivering on his promise to expand the US nuclear capability, while handing his buddy a gift-wrapped geopolitical easter egg.
Working hypothesis #2: Let us suppose that Donald Trump isn’t a Russian agent of influence. He might still withdraw, or threaten, British access to Trident as a negotiation lever in search of a better trade deal with the UK, when Theresa May or her successor comes cap-in-hand to Washington DC in the wake of Brexit. It’s a clear negative sum game for the British negotiating side — you can have a nuclear deterrent, or a slightly less unpalatable trade deal, but not both.
In this scenario, Trump wouldn’t be following any geopolitical agenda; he’d just be using the British Trident renewal program as a handy stick to beat an opponent with, because Trump doesn’t understand allies: he only understands supporters and enemies.
As for how fast the British Trident force might go away …
Missiles don’t have an indefinite shelf-life: they need regular servicing and maintenance. By abrogating the 1958 agreement, or banning Royal Navy warships from retrieving or delivering UGM-133s from the common stockpile at King’s Bay, POTUS could rely on the currently-loaded missiles becoming unreliable or unsafe to launch within a relatively short period of time — enough for trade negotiations, perhaps, but too short to design and procure even a temporary replacement. It’s unlikely that French M51 missiles could be carried aboard Dreadnought-class SSBNs without major design changes to the submarines, even if they were a politically viable replacement (which, in the wake of Brexit, they might well not be).

When the great AI singularity happens, you’ll be sorry you called Siri a bitch
Amy Alkon views with disdain a Quartz article on sexually harassing, inter alia, Alexa and Siri:
Quartz Seriously Wants To Know: Are You Sexually Harassing Your Phone?
There’s an unbelievable piece up at Quartz, reflecting a gone-mad sector of our society — ultimately driven by radical academic feminism (though typically not admitting or crediting its nutbag roots).Feminism was supposed to be about women wanting equal treatment. Now, as I like to put it, feminist no longer demand that women be treated as equals but as eggshells.
This article is a case in point. “We tested bots like Siri and Alexa to see who would stand up to sexual harassment,” is the headline. […]
First of all, if I could have Siri in either a bitchy drag queen voice or an Indian accent (from India, that is), which I love, I would. French or Italian or Eastern European would be fun, too. Because Apple’s rather boring about this — probably to serve an increasingly humorless and humor-attacking public — I think I have it on the British guy right now.
But I hate Siri and never use it.
The point is, you can change Siri to a man and harass the fuck out of it. I yell profanity at automated telephone systems when they repeatedly won’t accept my answer — both because I’m kind of immature and because there was this (probably mythic) idea out there that swearing would trigger a live operator to come on.
And per these evolved sex differences — we go for different Achilles heels in men and women when we’re attacking them. That’s because men and women are biologically and psychologically different, and men are more likely to be leaders, for example, and women are more likely to be caretakers.
Though male brains and female brains are mostly similar, these evolved sex differences lead to some differences in our psychology and how we present ourselves in the world (including the roles women versus men tend to have).
