I just round up stuff in my head. 1" = 25mm and 1 metre is 3 ft, a litre is just under 2 pints, a Kg is just over 2 lbs etc etc. Good enough for rough estimations. As Dena says old houses are a pain, my Edwardian one has 5" x 3/4" skirting boards, try buying 10ft of that these days. If I want a 1/2 cwt bag of potting compost I imagine a cwt was 100 lbs (was 112), 1/2 cwt was 50 lbs, divide by 2 = 25, bingo we need a 25kg bag, oh look, there is one!

B&Q sell carcassing timber at 95mm x 45mm and rough sawn timber at 100mm x 47mm, the latter being as near to 4x2 as makes no odds. B&Q sawn Their planed timber is 96mm x 44mm or 3 3/4" x 1 3/4" B&Q planed.

The trouble is that the UK have only become partly metricated, we buy petrol in litres but beer in pints, and groceries like potatoes have to be labelled in metric and imperial. We went to decimal coinage, but so far we still drive on the left and have road signs in miles. Of course the Americans have to confuse things as well, an Imperial ton is 2240 lbs, a metric tonne is 2200 lbs, and the American short ton is 2000 lbs. An imperial gallon is an 4.54 litres, the American gallon is 3.78 litres. The Yanks short changing everybody!

Don't even start on beer glass sizes, especially in Australia, they have different sizes and names in every town!! Oz glasses

The Settle and Carlisle Line Trust also have the the Station Master's House at Ribblehead

Both locations are superb and Bernie should really enjoy himself, with some pics later hopefully.

It's a total mess, 1/2 and 1/2 in the building and construction trade!!

A standard door is 2ft 6in x 6ft 6in, a standard kitchen unit is 600mm wide.

Plasterboard panels (dry walling to the Yanks) are 1800mm x 900mm x 9.5mm or what we would know as 6ft x 3 ft x 3/8in, or 2400mm x 1200mm or the old 8ft x 4ft x 1/2in.

You can't buy 1 cwt sacks of cement now it's in 50Kg bags.

A 4 by 2 timber joist is now 100mm x 50mm, if you buy it rough sawn, else it's 3 1/2" x 1 3/4" planed.

Yet you can still buy a 1/2" washer, and a 2" paintbrush + litres of paint ......

Total madness.

Ok, I will concede that one Tullio, it appears that "technically" you are correct!

that'll cost him a beer one day :-))

The moon and Earth both revolve and rotate on their way around in our solar system, but what is the difference between the two movements?

Rotation is when a planet or moon turns all the way around or spins on its axis one time. The axis of rotation is an imaginary line going from the north pole to the south pole. When a planet or moon travels once around an object this is considered a revolution. On Earth, a rotation is pretty short - it happens once a day! It is the rotation that makes the sun appear to come up in the morning and set at night. On Earth, a revolution is quite a bit longer - one year!

Mind you the French had one lasting 10 years, but they always have to be different from everyone else :-))

Beg's the question why would E.T contact us when all they need and more is on the Jouvian Moons

Probably because their split infinitives are as bad as ours and they want "To boldy go where no ET has gone before".

Doesn't say a lot for intergalactic Grammar really, but after a couple of Pan Galactic Gargle Blasters at the restaurant at the end of the universe none of them care anyway ....

Well Julie, I was being slightly mischievous there :-)) The "official" answer is that the bits never formed a planet in the first place because of Jupiter. But there are folklore theories of a lost Atlantis type planet that destroyed themselves, although there is no evidence for it.

The asteroid belt formed from the primordial solar nebula as a group of planetesimals, the smaller precursors of the planets, which in turn formed protoplanets. Between Mars and Jupiter, however, gravitational perturbations from Jupiter imbued the protoplanets with too much orbital energy for them to accrete into a planet. Collisions became too violent, and instead of fusing together, the planetesimals and most of the protoplanets shattered.

As a result, 99.9% of the asteroid belt's original mass was lost in the first 100 million years of the Solar System's history. Some fragments can eventually find their way into the inner Solar System, leading to meteorite impacts with the inner planets. Asteroid orbits continue to be appreciably perturbed whenever their period of revolution about the Sun forms an orbital resonance with Jupiter. At these orbital distances, a Kirkwood gap occurs as they are swept into other orbits.

As for Nibiru/Planet X

The Nibiru cataclysm is a supposed disastrous encounter between the Earth and a large planetary object (either a collision or a near-miss) which certain groups believe will take place in the early 21st century. Believers in this doomsday event usually refer to this object as Planet X or Nibiru. The idea that a planet-sized object will collide with or pass by Earth in the near future is not supported by any scientific evidence and has been rejected as pseudoscience by astronomers and planetary scientists.

The idea was first put forward in 1995 by Nancy Lieder, founder of the website ZetaTalk. Lieder describes herself as a contactee with the ability to receive messages from extraterrestrials from the Zeta Reticuli star system through an implant in her brain. She states that she was chosen to warn mankind that the object would sweep through the inner Solar System in May 2003 (though that date was later abandoned) causing Earth to undergo a pole shift that would destroy most of humanity.

The prediction has subsequently spread beyond Lieder's website and has been embraced by numerous Internet doomsday groups, most of which linked the event to the 2012 phenomenon. The name "Nibiru" is derived from the works of the ancient astronaut writer Zecharia Sitchin and his interpretations of Babylonian and Sumerian mythology; he denied any connection between his work and various claims of a coming apocalypse.

As for planets beyond Neptune and Pluto, they haven't been physically seen by telescopes yet, but the effects on other bodies if there WAS anything there HAVE been observed, leading to the conclusion that SOMETHING must be causing it. if a couple of extra bodies/planets are there, they will likely find them in time using modern science.

Actually, I think that they have confirmed some other snowball/Icey orbs that are actually bigger than Pluto some time ago.

Yup, I believe Ceres is one of them...

Ceres is the largest.

The asteroid belt is the region of the Solar System located roughly between the orbits of the planets Mars and Jupiter. It is occupied by numerous irregularly shaped bodies called asteroids or minor planets. About half the mass of the belt is contained in the four largest asteroids, Ceres, Vesta, Pallas, and Hygiea. Vesta, Pallas, and Hygiea have mean diameters of more than 400 km, whereas Ceres, the asteroid belt's only dwarf planet, is about 950 km in diameter.

Pluto is the largest object in the Kuiper belt, the tenth-most-massive known body directly orbiting the Sun; and the second-most-massive known dwarf planet, after Eris.

Discovered in 1930, Pluto was originally classified as the ninth planet from the Sun. Its status as a major planet fell into question following further study of it and the outer Solar System over the next 75 years. Starting in 1977 with the discovery of the minor planet Chiron, numerous icy objects similar to Pluto with eccentric orbits were found. The most notable of these is the scattered disc object Eris, discovered in 2005, which is 27% more massive than Pluto. The understanding that Pluto is only one of several large icy bodies in the outer Solar System prompted the International Astronomical Union (IAU) to formally define “planet” in 2006.

This definition excluded Pluto and reclassified it as a member of the new "dwarf planet" category (and specifically as a plutoid). Astronomers who oppose this decision hold that Pluto should have remained classified as a planet, and that other dwarf planets and even moons should be added to the list of planets along with Pluto.

Anyone older than a teenager today would have been educated to believe that Pluto was the official 9th Planet, because at that time other objects hadn't been discovered. Scientifically Pluto has simply been re-classified, in line with modern knowledge, but as the majority of the world are older than teenagers, they still REGARD it as the official 9th planet and probably always will do.

Another unanswerable question: If "space"'s time has no beginning, or ending, then how can we exist as a point of time, in it?

Yet, we obviously do.

That is more of a philosophical question than a scientific one. What some of us are saying is that space itself is infinite, but that events within it have a beginning and an end. Stars form, go supernovea and collapse. Human beings and animals live and die. Time has never had a beginning or an end, it is simply a measure of the duration between two events.

We have decided to base our time system on two levels. For general use we take one revolution of our planet and call it a day, then sub-divide it into smaller portions. For scientific applications we use periods of radiation which is more accurate. On the planet Zog they may base their durations on the average speed of a Yobba ray and sub divide it into yingtongs.

The one slight variation on all the above is the MS Access Database which was designed to handle dates by assuming a beginning on 1st January 1900. Each "point in time" as you term it since then, has a value in the number of days from that initial date, making it a simple mathematical task to calculate time durations.

The metric system is an internationally agreed decimal system of measurement that was originally based on the mètre des Archives and the kilogramme des Archives introduced by the French First Republic in 1799.

They are always interfering with a perfectly good arrangement :-))

Although the United Kingdom uses the metric system for most official purposes, the use of the imperial system of measure, particularly for use at home, is widespread and is permitted by the law.

We have aleady decimalised in the UK to some extent with losing 240 rather large pennies to £1, in favour of 100 rather smaller ones, which made some sort of sense to trouser pocket repairers. We were FORCED to buy our petrol (sorry USA, gas is what we cook with and heat our homes with) in litres, but we get around that by purchasing the stuff in multiples of £5 whatever the volume the price gives us, so up yours Paris!!!

As we have ten digits upon our hands and feet, it makes mathematical sense to have a base 10 system for weights and Measures such as the SI one, but only up to a point. And I tell you this. The day that I can't walk into a BRITISH pub and buy a BRITISH pint of beer in a BRITISH pint glass, I will personally start WWIII, I kid you not.....
