Keeping Your Advantage: Terrain and You [Weds, 3rd Period]

[atreideslioness]

Today when the students arrived, the Danger Shop was already set to today's terrain. Students would see pristine beaches stretching for miles, with an island about a half-mile offshore.

"Ladies and gentlemen, I present your compensation for having been without class while I was indisposed," Ghanima said cheerfully, although she was well away from the water, next to a trunk of gear. "You may be wondering what sort of terrain you need to learn about with a beach. Rather than build sandcastles, however, today we'll be learning about scuba diving. Water covers most of this planet, so being able to move through it is an important ability."

"Scuba diving may be performed for a number of reasons, both personal and professional. Most people begin though recreational diving, which is performed purely for enjoyment and has a number of distinct technical disciplines to increase interest underwater, such as cave diving, wreck diving, ice diving and deep diving."

"Divers may be employed professionally to perform tasks underwater. Most of these commercial divers are employed to perform tasks related to the running of a business involving deep water, including civil engineering tasks such as in oil exploration, underwater welding or offshore construction. Commercial divers may also be employed to perform tasks specifically related to marine activities, such as naval diving, including the repair and inspection of boats and ships, salvage of wrecks or underwater fishing, like spear fishing."

"Other specialist areas of diving include military diving, with a long history of military frogmen in various roles. They can perform roles including direct combat, infiltration behind enemy lines, placing mines or using a manned torpedo, bomb disposal or engineering operations. In civilian operations, many police forces operate police diving teams to perform search and recovery or search and rescue operations and to assist with the detection of crime which may involve bodies of water. In some cases diver rescue teams may also be part of a fire department or lifeguard unit."

She went on to explain how to suit up properly, as well as the mechanics of scuba diving. "Today we're looking at two ways you might need to use the ocean, and scuba, to achieve a goal," Ghanima continued. "There's three scenarios today, and you can choose just one, or all, if you have the time."

"So suit up, and enjoy the water."

"No," Elsa breathed, having forgotten about the tidepool entirely as Ghanima spoke, watching her with wide eyes, "I suppose there weren't. She sounds... ruthless, and effective, and one might not necessarily make up for the other at all, depending on where you're standing."

"Hence polarizing. I loved her very much, and mourned her long before her physical death," Ghanima replied. "Alia was ruthless indeed, and mesmerizing. Effective and besieged by demons. One person, in all their brilliance and their faults."

The crab had latched on to the end of Ghanima's stick, and she carefully lifted him from the water. "Like our friend crab, here. Should his shell become too small and no other is available, he may round up a posse of other small friends, and they will find the largest shelled creature they can and pry it from its shell. But then, they'll form a chain, largest to smallest, and swap shells almost simultaneously. It's called a vacancy chain, and can benefit up to twenty individual crabs, as well as the anemones that often live on their shells. Now all will grow and prosper... except, perhaps, the original owner of the largest shell."

"Now, would his initial assault on the shell's owner outweigh all the good he did for the other crabs? Or do they exist simply as two different things this crab has done? I suppose it depends on which crab you ask, although I have yet to meet a crab that was sociable enough to discuss philosophy with."

"Maybe they're pleased that they know something we don't know," Elsa suggested, smiling just a little bit as she leaned in to get a closer look at the crab. "Questions like that one don't come with answers for us as easily as they do a line of crabs in need of shells, I don't think."

She glanced up at Ghanima, biting her lip for a moment before speaking again.

"I don't know that I would ever want the answer to a question like that one to be so simple."

"The right answer is rarely a simple answer, sadly, despite what some arm-chair philosophers may claim," Ghanima agreed. "Sometimes, I think it's best that there *is* no one answer. I prefer infinite questions, myself."

"Questions that lead into other questions?" Elsa contemplated that for a moment as she reached a tentative hand into the tidepool, thankful for the wristbands that Barry had made for her, to stroke the back of the little starfish she had spotted before. "I think I might prefer questions that lead to answers that raise more questions, myself. Discovery, and curiosity, and learning -- I can appreciate when one leads to the next."
