She spent nine years working in laboratory and clinical research.
A lifelong writer, Dianne is also a science fiction & fantasy novelist.
Stone-throwing catapults (palintones) represented a design shift.
A catapult featured in the siege of Motya in 397 B. Catapults evolved from handheld compound bow devices called gastraphetes and larger bow machines. Used for firing arrows, these catapults, called euthytones, were made of wooden arms and frames with springs and a trigger mechanism.
Engaging students with real-world examples of catapults offers many opportunities to think outside the textbook, and encourages them to expand their approach to math and science problems.
While the slingshot still holds its place as a classic toy example of catapults, there are larger and flashier forms of catapults that provide entertainment.These EMALS can operate in rapid succession and are more efficient than their steam-powered predecessors.They allow heavier airplanes to be launched from carriers, leading to increased range and strike capability.Catapults represent excellent tools for various educational needs.With the preponderance of science, technology, engineering and mathematics (STEM) school programs, catapults allow educators to demonstrate a broad range of discussion topics.Launching a projectile with a catapult displays the geometric arc known as the parabola.In addition to calculating the force of gravity a projectile experiences, students can use quadratic equations to build a better catapult.Enormous steam-powered catapults, hundreds of feet long, launched aircraft from the short runways of the carriers.The sheer size of steam catapults proved to be a liability, taking up significant space and requiring the perfect amount of steam to launch airplanes depending on their weight.Dianne features science as well as writing topics on her website, personal: the topics seemed insignificant, or else too important to be aired for an audience of strangers.
