You'd have to filter for 'trendy' ones though. Something like cocktail bars based out of shipping containers on top of abandoned multi-storey car parks or cocktail bars with the same names as businesses at the same address th

I can also remember my teacher explaining calculus and doing stuff like deriving the formulae for volume of a cone, it was pretty interesting to me; I remember having lots of ideas for engineering problems that could be solved with techniqu

Also it would be be cool if the density of the lattice could be varied. Bone structure is a great example of this, it's a 3D Voroni diagram where areas of smaller cells are indicative of stress concentrations.

Yes. The only reason I can think of that you would do this is to build some kind of hybrid airship that generated some lift from wings to increase MTOW (lifting capacity) but still has all the energy efficiency of low speed and therefore lo

The particulate filtering technology for Diesel engines has been rushed to market. As well as DPF filters, EGR valves are another thing that get clogged with soot and fail if you do too many short trips. The diesel engines Vauxhall/Ope

Maybe this is what she was getting at when making the comparison to bone structures, but from seeing how it deforms under load in the video, it seems that to realise its potential for serious structural applications this needs to be bonded

The 'City of London' is a quirk it is actually a very small borough within the city of Greater London, which has a population of something like 8 million and is very roughly up to zone 6 on a tube map. For the regional population

I don't know about the US, but the UK construction industry is unbelievably slow and bureaucratic compared to other European countries in general.

I'm not Scottish but I live in the Highlands. I think it's less to do with nationalism and more to do with to do with security of tenure. A lot of rural housing and farmland is owned by these large estates. The houses that have no

Just to add. It can be implemented on an 8bit micro controller. It's pretty similar to I2C or SPI but with a bit of error checking thrown in.

I heard from a colleague who went on a tour of a CCTV control centre in London that it was being used on surveillance camera live streams at least 15 years ago.

Construction is a much more fragmented and there is no standardised software or mature data interchange format. Unlike say, aerospace, where the client is the organisation that mostly designs and builds the thing and is a gorilla that can f

Yes but in cities like LA which are planned around cars the major arteries are 3 lanes in each direction, so you can put up signs saying $200 fine if you use the bus lane, give buses priority at traffic lights, run articulated buses with pr

Depends on the city though. Bus routes in London haven't changed for a long time. The buses I used 30 years ago all have basically the same routes. There are probably routes that are over 80 years old. But buses could never be grade se

But if you are comparing to highways in the US then surely a fair comparison would socialise some of the capital and maintenance costs of the infrastructure. Even so 30-40 year payback on the whole lot is not that bad. SNCF is probably in d

It's not a money loser. TGV is highly profitable in France. All the major intercity routes in the UK run at a profit and these operate at 125-140mph, which is high speed by US standards.

Overpriced. Overcrowded. Unclean. Cramped. Occasionally unreliable. We don't have any high speed rail apart from the link to Paris, but our standard intercity trains have connected most major cities at 200kph since the 1970's whic

Normal speed is up to 200-225kph in the UK. Commuter rail up to 160kph. Metro 60-100kph

I don't think the difference is as big as you think it is e.g Central London to Central Glasgow. Tube 30mins -> Euston 4h15m -> Glasgow Central -> 10m cab ride = 4h55m Tube 30mins -> Liverpool St 45m -> Stanstead 1h -&gt

This is very interesting, there is definitely a big opportunity for CAD software that does things differently. A lot of the supposedly 'BIM enabled' and 'parametric' CAD software in use in the construction industry suffe

Chicago's bedrock at 80' is relatively close to the surface. In central London you would hope for highly compacted sand at about 50m (150') deep. Above this is London clay and a whole lot of river basin sediment. London'

I think £27k is the UK average or the southeast average? I thought the london average was closer to £60k? I can't find a source for that though.
