I was walking down the street one day
in the very merry month of may
with a diamond tipped extendible umbrella drill

Landed 5000 years ago and still shiny as a new penny!
The Spanish tracked it down as the locals had used it to make arrow heads and other weapons and thought they must have a mine but just found a 35 ton lump of it and then got bored. Over 100 tons landed altogether though!
The composition is very similar to Tuts dagger and I can see why tools made from this stuff are high value - they have certain sheen.
Except you might as well just get your phone out of your pocket.....
You really do not understand the statement that can be made by spinning a watch around on a chain.
I intend to get micro:bit so I can chain one to my jacket so when I whip it out and spin it round it writes "Well that was fucking pointless!" in the air as it spins.
I'm not sure the BBC were wrong in commissioning this - just very unlucky not to know the Pi Zero was coming out.
I'd guess from the pricing of this, compared with what I've seen of the Pi, that even if they only sell a couple of hundred thousand they will be well into somewhere 'profitable'.
I avoid contactless since a friend I was with managed to spend rather a lot in pub - rather more than we could have drunk and we decided it must have been a deliberate scam in the bar in question.
In the co-op yesterday a young lad bought a lot of stuff with a contactless card - his behaviour suggested it wasnt his card. If the co-op can show his parents the items bought he may well get his arse kicked.
Fortunate enough to have an equally pyromaniacal bloodline. Lots of cannons (grandad had a 10lb box of gunpowder from somewhere) but the most impressive thing I saw and heard was a giant plastic bag (10' by 6' ish) filled with coal gas from the cooker and the correct amount of oxygen from a dentist.
This was bonfire night but when the flame on the paraffin soaked string reached the plastic the detonation was phenomenal (my memory still swears it had BANG! written across it). Not sure if it was deafness or the fact everyone within 5 miles was trying to work out what the fuck that was meant the silence was deafening for quite a while. Then, from the 50 or so party goers in the vicinity, hysterical laughter borne of shock for about half an hour.
Several people shat themselves. I was 11 at the time and found the plane dropping out of the sky fun as I had flown before and felt safe but after we passed the storm the hostess who was looking after me (I was travelling alone) spent some time getting tissues and things for the poor buggers who lost it. Luckily the flight was only about 1/4 full as I think they ran out of loo paper.
Wings are profiled - they thin towards the tip - think of it a bit like a kids drawing of a bird in flight.
I was flying across the atlantic in 1970 long before they had decent weather warnings and we hit a thunderstorm and free-fell 3000 feet before the wings seemed to do that. The plane smelt a bit funny after that. I was allowed on the flight deck a few hours later and the co-pilot was still shaking.
My local exchange went FTTC. The village the exchange is in went from around 17Mb to 30Mb (I dont think anyone wanted to pay for 70 - they didnt need 30 anyway) .Those of us outside the village had our cabinets re-assigned. Mine was a couple of miles from my house and is now 6 miles of copper away at the exchange. So the whole area is now FTTC but those in the village are a bit better off, those outside the village are no better off. BT put in about 20 yds of fibre and got a huge wedge from the council.
Mythbusters are plonkers. Archimedes was on smart bugger and didnt just fuck up for laughs. Its not hard to get a bunch of men to direct and focus mirrors on to a boat - they just need to bring the reflections in one at a time, or if there was a frame used the man who designed the antikithera mechanism could easily get a simple frame to work.
Tosh!
I spent many years knocking up microchips which were simulated using spice and digital simulators. We NEVER simulated at the quantum level which is how the devices really worked but the simulations using simplified models were accurate enough to get working devices with tens of thousands of components. I'm guessing they do similar with devices of billions of devices today.
You dont need to model convection and turbulence on micro of macro scales to model climate. Stupidly accurate weather perhaps but if you have a model that can give you reasonably accurate correlation with past events over the time data is available and it predicts temperature rises in the future only a bloody idiot would ignore it. It might be wrong but its got a far higher probability of being right than casual disinterest.
The brain is not just a collection of neurons and memories. Its layer upon layer of filters and simulators built from experience but also built on the ready built in models from our genes and whatever goes on in the womb.
It would be like trying to run an ARM binary on an Intel PC.
I had a friend who lost a leg and 30 years later would still sometimes get out of bed and fall over. Imagine what it would be like waking up in something that was just slightly wrong everywhere.
@scatter Mass production is the key - a grid connected inverter made from silicon and not lots of hand fixed parts should cost around £20 for the controller and lightning protection, £5/KW for the silicon power stuff and £30 or so per KW for the transformer that is required by law for grid connection though probably not necessary. I looked into making these myself - the upfront costs are enormous but if you are producing millions or so that is insignificant in the long run. I was informed there are designs for these already - just for now its not 'what the market is looking for'!
So for a 2kw windmill you are looking at around £100 for the inverter. A 1kw car alternator is around £50 so say £100 for a 2KW and all you need is a pole an axle and some mass produced blades. Stick it up the side of a house and it WILL produce enough juice to pay for itself in a couple of years.
Its very cost effective - just not 'efficient'. Cheap cheap electricity - what's the problem?
Hats off to them but when I was cutting my teeth making NMOS chips an 8% efficiency polysilicon solar panel took about 20 years to pay for itself. You could get couple of thousand transistors on a chip for $100 and electricity was around 1p a unit.
Now electricity costs 15 times as much, you can get 100,000,000,000 transistors that run 5000 times as fast for $100 and a solar setup takes around 10 years to pay for itself.
I do wonder if someone had just concentrated on making 8% polysilicon panels they would now be so cheap they would be used instead of tiles - or indeed metal roofing sheets. I could be putting out >20KW from my barns and my neighbouring farms all have barns that would be 100KW or so.
The same goes for wind - mass produced 1 or 2kw units should be in the £300 region and pay for themselves in a couple of years. They might not be as physically efficient but effectively free to the consumer in the short term.
