True. When a car ran into the back of me at a roundabout (he thought it

round the inside metalwork of the tailgate made the car safe to drive

It surely depends on multiple factors, including the specific vehicles

(It was eventually totaled by her insurance company.) I had several
scratches on my front bumper and a single scratch on one fender.

The street was not wide, so the BMW ended in the back of
a Mazda 626, moving the 626 rear bumper into the driver seat.
The car that was parking in front of it was a total loss, too.
With the help of a crowbar, they could drive the BMW to the next

OK, so some British-English spellings have mutated over the years: few

Gaol always threw me as in \'The Ballad of Reading Gaol\'. I suppose it\'s in
line with Gerald and so forth. I\'m never sure about disk and tend to
alternate. \'Ax\' is another one. This newsreader flags \'axe\' but I tend to
favor that spelling.

The one difference that works the opposite way round is the
pronunciation of \"herb\". British pronounces the H whereas American often
omits the H sound \"erb\" as if it were French.

I\'ll go with herb. \'Erb\' sounds affected to me. When I was a kid I had a
book about Indians, excuse me Native Americans, where the medicine man was
named Herb Gatherer. I thought Mr. Gatherer\'s first name was Herbert like
Herbert Philbrick until the dime dropped.

Do other English-speaking counties than the UK have the absurd \"an
historic event\" where \"an\" is used even though the H in \"historic\" is
sounded? I would normally say \"a historic event\", \"a hotel\" just like \"a
hedge\" or \"a helmet\". If I wanted to be pretentious I suppose \"an
\'istoric event\" or \"an \'otel\" are acceptable, but never \"an\" with a
consonant or consonant-sound, nor \"a\" with a vowel or vowel-sound.

I play fast and loose with \'an\'. Acronyms really mix it up. \'An USB port\'
just doesn\'t cut it.

I consider myself luck to have joined the workforce at the very tail end
of vacuum tube logic. You can implement a NOR gate and you can build
anything from NOR gates if you don\'t mind going insane.

Square D\'s first shot at solid state was called NORPAK. Each plug-in

them up on the backplane with tapered pin jumpers that you set with
something like an automatic centerpunch.

But I believe that the concept of a speed limit for bicycles doesn\'t

Some of the local multi-trails have 10 mph speeds posted but they\'re a
suggestion. The iron fist in the velvet glove is if there are too many
valid complaints the trails will be closed to bicycles completely.

Some of the single track trails are closed to e-bikes. It\'s not like there
are cops hiding behind the pine trees to enforce it. There aren\'t that
many e-bikes yet so we\'ll see how it goes.

I find that when I\'m going downhill I wimp out before I reach the speed
limit: even 30 mph seems bloody fast on a road that has imperfections in
the surface - and the sort of roads that have steep hills tend to be
those
outside a town, so with a 60 limit.

There is one hill close to me that has a portable radar setup with a
screen to tell you your speed. The limit is 35 and it will flash if you\'re
going faster. I\'ve tried to get it to flash with the bicycle but it\'s too
far out on the flat and I\'ve never been able to get more than 28.

You\'re right. 30 on a bicycle feels a lot faster than three times that on
my Suzuki V-Strom. However, I have more scars and broken bones from
bicycles than motorcycles so that may play a part.

Buck and boost converters don\'t use their transformer core material all that effectively.

Using switching circuits to set up a pulse width modulated waveform that will rectify to the desired voltage, and putting that through a tranformer to get the step-up or step-down that you need lets you push a lot more power through a given core volume,

Exactly. It\'s weird that they survived for so long without words to
differentiate colours which most of use see as being different. The
various colours at the blue end of the rainbow (blue, indigo, violet)
are not as easy to differentiate, and I can understand *those* being
thought of as various shades of blue, but red, orange, yellow, green,
blue are all colours that are fairly distinct and deserve individual names.

Be careful of that \"most of us\".

Almost everyone can tell blue from red or green. Telling red from green
though affects about 1 in 12 men in the UK (other races may vary).

It\'s not 1 in 12. I\'ve only ever known ONE person who was red/green colour blind.

there are six /distinct/ colours in the spectrum, red, orange, yellow,

There\'s a colour there, but I don\'t think of it as having a special

whether there is a name for the colour.

Perhaps an artist or clothes designer would, and perhaps they have a lot

Have you ever purchased paint?

If you ever go to B&Q, do not purchase their more expensive colour matched paint. You give them a piece of fabric/whatever, the computer scans it, and it \"mixes\" the right paint to match it. Except it\'s a lie. It just picks one of about 300 colours from a list. Which you can do by holding the fabric up against the chart on the wall and save money.

Perhaps an artist or clothes designer would, and perhaps they have a lot
of other colour names to help them.

To get around the need to name every color, color numbering systems
have been devised. One extremely popular one is the Pantone Matching
System:

Human cone cells come in three wavelengths, roughly r-g-b, so if we

Having at least one between each makes sense. If your eye detects R and G about equally, there should be a name for that.
