Fun with Physics Special Topics

I recently discovered the online journal Physics Special Topics (current issue, archives). These are essentially collections of student articles on various topics. Here is how the journal describes itself:

FOCUS AND SCOPE
This is an undergraduate journal for year 4 (MPhys) students in the Department of Physics and Astronomy at the University of Leicester. The journal accepts brief papers on topics original to the authors. It does not accept reviews or summaries of other peoples work. It is managed by an editorial board which rotates round the student body overseen by a member of staff. The journal forms part of the assessed element of the MPhys degree. Assessment is by number and quality of accepted publications and referee reports.

The students are writing serious article on a wide variety of topics, some of which are inspired by by games and science fiction. As science goes, these is not exactly cutting edge, but it sure is fun. Some of the articles that caught my eye are:

How Heroic is a Hero? An exploration of the probability distribution behind character creation in the D20 system.

Niven Rings looks at some of the physics of Larry Niven's Ringworld.

Can superhuman muscles stop bullets?  Ask the question, "Just how bulletproof is Superman, anyway?"

And much more.

This is perhaps slightly off the usual theme of this blog, but surely playing games and reading SciFi has raised a few of these questions in the minds of gamers - "Just how what that work, if we actually tried it?" - Like many things, the fun is in the finding out. 

If one of these articles catches your interest, please post about it below. Have fun!

The Origin of Battletech

I was reading a review of the Battletech games universe at BoardGameGeek when I came across this fascinating comment:

Lance McMillan wrote: ... Weisman's basic system for Battletech was an obvious derivative of the ancient (1930's vintage) "Fletcher Pratt's Naval Battles" game: players rolling dice to determine the location and extent of damage inflicted by each individual weapon, and then checking off little boxes on status charts to keep track of the totals. ...

I had often wondered about predecessor games to Battletech. I assumed they existed, but I had never seen one. A little voice in the back of my head tells me I knew science fiction author Fletcher Pratt wrote a naval battle wargame, but I never made the connection until now.

My interest peaked piqued, I dig a bit more and find this old Sports Illustrated article:

Pratt was a writer and a naval expert (before he died in 1956 he had written some 60 books about naval and military affairs), and one day, in 1929, "bored with seven-card stud, backgammon and craps," he and a group of maritime minded friends decided to invent a naval game. They bought a division or two of model ships, pushed back the furniture in Pratt's living room and set to gaming. By the time they were done, they had come up with the rules for a mammoth contest that required up to 60 people on a side, a large ballroom to play in and vast fleets of accurately scaled ships, and the Naval War College started sending down experts to take lessons. [See The World's Most Complicated Game at SIVault, it's a good read.]

Pratt's game even had its own version of Battevalue:

There was a vast formula for calculating the fighting power of each ship: (Gc[2] X GN + Gc'[2] X Gn' + 10TT + 10A[2] + 10 A'[2] + 10A" + 25 Ap + M) Sf; + T, and elaborate tables for telling each captain what had happened to his ship when the turn's shooting was over.

What that formula means I have no idea, but now I want to find out. I located a source for the original rules at John Curry's History of Wargaming Project, which also has more details about the game:

One of the main facets of the game, the gunnery, is commonly decided by dice. Therefore, games can seem to consist of large numbers of dice rolls reflecting the low hit-rates of long range naval gunnery. To many, the sheer number of dice can make the game seem dull. Pratt aimed to change this by using estimating ranges as a way of determining hits. He also experimented with shooting, darts and tiddle-winks against paper silhouettes as alternatives, but he settled on estimating as the final method. The inspiration of using estimating the range for gunnery accelerated the pace of the game and gave naval wargamers control of the most important aspect of the naval warfare, namely hitting the other side.

It even has it's own miniatures.
OK. I'm sold. I want it, if only to satisfy my own curiosity, and it is available from Amazon.

After communicating with John Curry, it seems that Featherstone's book only summarizes the rules, and the full rules are not currently in print. Mr. Curry is currently working on a new book which is to include Pratt's original rules and more. I might have to wait until that is available.

*** UPDATE 5/22/09 ***

I had another email from John Curry informing me he has opened up his ship cards for download. Here is an example.

From what I can make out, the lower portion is a list of total damage accumulated (1st and 3rd unlabeled columns), and the 2nd and 4th columns give the effect of damage on the ship. At the point where the ship has accumulated 10,721 points of damage, it is only capable of moving at 8 knots, has lost 6 of its 8 "4.7 inch" guns, and 3 of 4 torpedo tubes.

This is simpler than a Battletech Mech sheet, but it serves the same function.
