Didn't the Brits vote for this six years ago? Why are they complaining they got what they wanted?

^(It was just Project Fear, really Britain is not in recession, Europe is not returning to growth, we have always been at war with Eastasia.)

SpaceX only did crewed flights to orbit after a huge influx of NASA/Space Act money and could lend against future milestone payments as part of the CRS contract. It also had a lot of handed down tech, like the FASTRAC engine design. It really blurs the boundaries between "actually private" and "aren't truly private projects".

It was, however, first to reach orbit uncrewed on purely private funding (Merlin-1 was still heavily based on donated taxpayer technology) with the last flight of Falcon 1. The CRS big bucks enabled SpaceX to skip Falcon 5 for Falcon 9.

Scaled Composites won the Ansari X-Prize by flying suborbital, which was also a privately funded SpaceShipOne and White Knight. It was the first ever privately funded spaceflight with entirely privately developed technology. The next company to achieve the same was Blue Origin.

A breaker will trip on a peak current. It's not much of a 30A breaker if it lets 42.5A past now, is it?

However, don't just believe some random yahoo on the Internet with electrical safety, test it out in a controlled and safe setup.

Use peak voltage, not RMS. The peak voltage of a US AC supply is 170V (peak of the cycle), so if OP specifies for 30A, your example of a a 3600 watt nominal load is 4 ohm reactance or resistance.

Solving for current through that 4 ohms at 170V gets 42.5 amps. If specified for 30A + 5A slack and so running through a 35A breaker, that breaker would trip.

You can also just multiply current by root(2) (1.41) to get the peak in the AC cycle, but I like to show how the figure is derived.

You're replacing a fully turned on FET (which, you'll recall, has much less impedance than a few ohms!), you won't get that sort of current into the MCU's sense pin, it's a very high impedance.

These guys work on a PIR sensor to detect motion and the solar voltage to tell when it's dark.

What you need to do a bypass on the PIR sensor, and that's really easy.

A PIR has three pins, a supply rail, a ground rail, and the sense line. They pull sense up when a moving subject passes the PIR by turning on a FET. Cut the sense line and solder a small resistor (e.g. 4.7 ohms) or just a bridge between the sense trace and the supply voltage.

Fair warning in advance: It will kill the battery.

When the Glazers acquired the club, they used borrowed money to finance their acquisition (including an utterly stupid 20% APR PIK loan!), and they assigned that debt to the club itself.

So Manchester United took on around £750 million pounds of debt to make itself private in the early 2000s.

It's refinanced (and refloated) since, but remains in debt and has to service that debt - It is still around £350 million in debt, has spent a billion pounds on interest payments

For this service, the Glazers pay themselves around £30 million a year.

On the diagram, the finance works that way to make it easier to see!

That would be a meteor, from your description bright enough to be a fireball. Space debris doesn't often leave lasting trails and it moves a lot more slowly.

Report it to AMS, so they can correlate sightings and give you info like this.

Also, for those wondering why I'd suspect a stepdown: 120V halogens were more widely available with a better CRI than 240V halogens, and Artemide sells these as lamps suitable for artists and draughtsmen.

Similarly old universities are:

University of Sankore - 989

Oxford University - 1096 (or 1231, when it was chartered)

University of Salamanca - 1134

Also, the University of Bologna has only been continuously operating since 1945. There was a big argument among European cartographers and it had to suspend operations until they had their maps sorted out.

Right, that answers it. Your transformer is in fact a fluorescent ballast. I suspected it was either a 2:1 stepdown or a ballast.

Replacing it is possible, as Artemide generally made for the European market, however a cursory search around lighting suppliers doesn't find any among Artemide parts suppliers.

It will be better to replace the lamp holder for a standard bayonet or screw, then you can use any number of lamps in it.

There's almost no info on this online (and Artemide likes to use the same name for many different products over the years), but the lamp's operating voltage is important here. What does a bulb say it's rated to?

Come on MPs, it's a bit blatant if even Qatar knows your price!

I saw the photo you posted.

It is not an explosion risk.

It's badly made, but it won't blow anything up.

In the 1990s I went in to HMV, and said "I liked Oasis' first and second albums, but I'm not big on the new one. What'd you recommend?"

I walked out with The Stone Roses and never looked back.

That's a cenotaph, not a head stone. A cenotaph commemorates a person who's body is interred elsewhere, lost, or cremated.

A priest should know this.

Flame retardant just means it won't sustain a flame itself. Doesn't say "fire resistant".

Electrical tape will warp, char, and melt.

Almost? The Harley-Davidson motorised bicycle was, in fact, a motorised bicycle!

Benz had been making them earlier, but while Benz had good engines, he had no idea what made a bicycle work. There had been experiments with rotary wheel-engines, trikes, Benz came back with the Patent-Motorwagen, etc.

Millet's design of the 1890s set the scene for how to do it, however.

The Thomas Auto-Bi is even more obviously a bike with a motor bolted on it! By the time of the FN Four, it had become pretty ridiculous, but people wanted power.

Oh, and I best not leave this without mentioning the Roper Steam Velocipede, which is exactly what you think it is.

I love this.

A first world developed nation, unable to go into space, pays a third world developing nation for its superior technology.

Fellow Brits, where did we go wrong?

^(Britain cannot into space)

17% of the British populace voted for complete chaos.

They're getting it.

It'd be quite fun to watch if it weren't for the many crises it's spawning.

Fanjingshania is the earliest jawed fish known, at 439 million years old of the lower Silurian, and could be to be a member of the group which placoderms (and all other jawed fish) emerged from.

However, we believe placoderms and all other fish (the ancestral group which would later become cartilaginous fish, acanthodians ("spiny sharks"), and bony fish, had already diverged at this point, and likely did so during the Ordovician.

There is an outside possibility that Fanjingshania is a member of that basal population, from which all other fish groups came (and, therefore, all vertebrates) but this is looking unlikely, as it's too late and already carries features giving it affinity with the acanthodians, which have no living relatives.

A 2016 study found all cartilaginous fish to be more closely related to acanthodians than any other group and recovered acanthodians as stem-chondrichthyes, while another group in 2012 had found acanthodians to not actually exist and assigned all its members either to Chondrichthyes (cartilaginous fish) or to bony fish.

Most taxonomists at the moment seem to be agreeing with the acanthodians as stem-chondrichthyes model.

Additionally, working out how these swam was very important because these had the earliest pelvic fins. Vertebrate legs emerged from pelvic fins. It can give clues into the later evolution of tetrapods.

TL;DR; This is probably a member of an early divergence from the lineage which resulted in vertebrates, not an ancestor of vertebrates itself.
