Meanwhile in Japan... Smoking Manners

Today's trivia is a collection of images produced by the Japan Tobacco company, a part government owned company which was the result of a long nationalisation of the tobacco industry.

As you might therefore imagine, smoking is somewhat popular in Japan...

The Japanese people are regarded as overly polite. They also have a sense of humor. The images included are some of the more amusing of 70 produced by the marketing campaign.

Sandwich Sandwich Scotch Egg

Image from Bristol Eating Adventures

Today's trivia was started by an interesting question around the Sandwich Sandwich Scotch Egg. Thus we'll see where this takes us.

The latest understanding of Black Holes was used for the rendering of the scenes in Interstellar

How many Sandwich Sandwich scotch eggs would be required to create a mass large enough to collapse under its own gravitational field, thus creating a black hole?

Recommended units:

• Capacity of an English bowler hat
• 45 foot truck (45 tons)
• Capacity of the House of Lords
• Solar Masses (1 Solar Mass = 1.9 to the power of 30 kg)

The current understanding of black holes if that they can form from a start about three times the mass of our own Sun. Estimating one scotch egg at 0.5 kg gives us 12 nonillion kg.

Which falls faster in a vacuum? A Sandwich Sandwich Scotch Egg or a feather?

It is clear that unless the Sandwich Sandwich Scotch Egg is an exotic material, it will fall much like the bowling ball. However if the distance is sufficient and the mass of the Scotch Egg is high enough, it will draw the feather to it under its own gravity.

What velocity might be required to penetrate the reactive armour of a modern Challenger main battle tank with a Sandwich Sandwich Scotch Egg?

Modern main battle tanks use sophisticated armour, for example the Chobham reactive armour of the British Challenger tanks. Composed of ceramic tiles encased in a metal matrix and bonded to a backing plate by several elastic layers, it would take a truly mighty Sandwich Sandwich Scotch Egg to defeat such armour.

Misusing some sensible calculations from here if we compressed the Sandwich Sandwich Scotch Egg into the size of 1cm sphere and fired it directly at a sheet of 1cm thick plate steel, it might only need a velocity of 126m/s to penetrate. Clearly we're going to need a larger Scotch Egg.

How much damage could be potentially dealt with a single Sandwich Sandwich Scotch Egg under Dungeons and Dragons rules? Official D&D Rules V3.4

This one really depends on how you classify the Sandwich Sandwich Scotch Egg.

Working from If we consider some of the possible options we get the following list

• Inappropriatley Sized Weapons: -2 attack penalty for each size class difference. -4 penalty if the creature is not proficient with the weapon.
• Improvised Weapons: Automatic -4 penalty for non-proficiency, can cause critical hit, can be thrown.
• Thrown Weapons: Uses character's Strength modifier, One handed weapons count as standard action. Can cause critical hit.

Clearly we should treat the Sandwich Sandwich Scotch Egg as an improvised thrown weapon and give it a bonus to critical hits for good measure!

Can you suggest some collective nouns for the Sandwich Sandwich Scotch Egg?

• A tumble of Scotch Eggs
• A collapse of Scotch Eggs

Mornington Crescent

Full size version

Todays trivia is all about a panel show game known as "Mornington Crescent".

This game was first made popular by the Radio 4 show "I'm Sorry I Haven't a Clue" in 1978 and has been played in every season since then. (It is mooted that its origins belong slightly further back, perhaps being named after another station, Finchley Central).

The radio show has been hosted for a long time by the late Humphrey Lyttelton. Now run by Stephen Fry, Jack Dee and Rob Brydon.

The Tube Station

The game was named after a tube station on the Northen Line in Zone 2. First opened in 1907, and later closed in 1992 for refurbishment. It then faced the real prospect of remaining closed forever until a concerted campaign was launched by fans of the game to have the station reopened. This campaign was successful and in 1998 it was reopened.

A English Heritage plaque commemorating the late Willie Rushton, one of the longest running contestants on the Radio 4 panel show has been mounted inside the station.

Introduction to the Rules

The game is classified as a complex strategy game played traditionally on the London Tube map. (There have been mootings of playing the game on other city metro maps, but these are generally folly.) It is suitable for two or more players and can be played anywhere. Having access to a tube map may be considered a useful reference unless the blind variant is played.

There is an adjudicator who will decide whether moves are valid and will ensure the orderly procession of turns.

The basic concept is that players take it in turn making moves which bring them close to the end goal of Mornington Crescent. The player who lands on Mornington Crescent (and it being considered a valid move) will win the game unless of course they are playing the reverse variant in which case players attempt to perform the opposite, starting at Mornington Crescent and moving towards the start.

A Cavalcade of Rules, Variants, Versions, Stratagems and Protocols

For the more advanced players there are a plethora of additional rules that can be applied to the game. Traditionally on the radio show a particular ruling is indicated which players need to be aware of when they make their moves.

From the archives at least 76 specific rules have been identified. They range from the cunning and devious to the outright silly.

Some examples of rules which make for interesting play:

hugo’s 2nd stratagem

Moves across consecutive rows are prohibited unless you’re in Knip.

north london rules

Contraflows are inverted, and to avoid Triangulation, Dollis Hill will be wild.

simplified version

Stovold’s Defence is still allowable during Forward Triangulation, but Back Doubling may only be attempted after a Northern Approach.

Knip and Huffs

We would be remiss in our duties if we did not include special mention to some of the moves and concepts that make up the game:

• Huff - Landing on a huffing station allows the previous player (the huffer) to huff the current player, thereby reversing order of play until another huff is performed. This of course voids the 7th rule.
• Knip - The player is required to miss a go as a result of lateral shifting. There are exceptions to this (hugo's 2nd stratagem being one case)
• Strike Move - Players can knock their opponents out of position (only in Devonshire variants)
• Stymie - To prevent a players move by blocking their passage (See Boxing in for more detail)
• Back Doubling - Only possible after the Northern Approach

Luna-9

Today's trivia hopes to cover a slightly less well known Moon landing; from the Soviet Union space program.

The year is 1966, the Soviet Union had had mixed success with landings on the Moon. Since the start of their mission to land on the Moon in 1958, they had launched 20 missions. Only two missions, both in 1959, had succeeded. Luna-2 successfully (intentionally) crashed into the surface of the Moon, Luna-3 provided the first photos of the far side of the Moon.

However they were learning hugely from their space program and had refined the launch vehicle which would take the next mission, Luna-9 to the first soft body landing on the Moon.

Launch and Approach

The launch vehicle was the Molniya-M (a design derived from an earlier ICBM design, last used 2010) which operated as a four stage rocket. Was considerably more reliable than previous rockets and provided enough lift to get the 1.5 ton lander into orbit, set it into a gentle spin and provide the final velocity to get it into a trajectory towards the Moon.

A helpful simulation of the entire launch, approach and landing

This journey lasted 4 days and included a crucial course correction where the lander pivoted over so its rockets were directed at the Moon which allowed it to start its descent towards the surface.

The Luna-9 Lander; the body contained the flight control systems, the front contained the probe payload to deploy to the lunar surface

The lander was equipped with radar altimeter which allowed it to determine how high it was from the surface:

• At 25km from the surface the retro-rockets fired to slow descent
• At 250 meters the retro-rocket cut out and 4 stabilising rockets fired
• At 5 meters a contact sensor fires, and the probe is jettisoned from the top

The probe then bounced on an inflated air cushion before coming to rest on the lunar surface. Once stationary, the air cushion is jettisoned off.

A reconstruction of lander deployed the probe safely to the surface

The probe itself as comparatively quite simple. It consisted of a hermetically sealed container in which was held:

• radio equipment
• program timer
• heat control system
• geiger counter
• television system

Images Received

Approximately 250 seconds after the probe came to a halt the probe sprang open its four petal shaped panels and began a photographic survey of the lunar environment.

The probe for the mission was equipped with a simple imaging system (by modern standards). It consisted of a television camera which pointed upwards and a mirror which was angled out towards the lunar surface. The mirror was rotated by a motor at a constant rate.

It would start recording images and broadcasting them via radio transmission back to Earth to be received by Soviet Union radio telescopes.

This also allowed the Jodrell Bank Lovell radio telescope to receive the same images.

Lovell Radio Telescope

It was quickly realised that the received signals were encoded in Radiofax, an internationally agreed standard for sending images between newspaper companies around the world.

"A Muirhead facsimile convertor and receiver were rushed out to Jodrell Bank from the Daily Express newspaper offices in Manchester. When the signals received the next afternoon were played through the machine, out scrolled, line by line, the first ever picture of the lunar surface taken from the surface." -- quote Professor Tim O'Brien

Perhaps to the Soviets dismay, the Express published the first image ever taken from the surface of the Moon before they did.

First photograph taken from the surface of the Moon in February 1966 by the Soviet lander Luna-9

Successes

The mission achieved a number of firsts:

• First soft body landing demonstrating the kind of flight control systems which would be required to land people on the Moon
• First images transmitted from the surface of another body in space
• Confirmation that the Moon's surface could support a foreign object; theories at the time predicted things might simply sink into the surface
• First recordings of radiation from the surface of the Moon (30 millirads per day)

Last contact with the spacecraft was at 22:55 UT on 6 February 1966, after which its onboard batteries expired.
