"This is an introductory text intended for a one-year introductory course of the type typically taken by biology majors. Algebra and trig are used, and there are optional calculus-based sections. (There is an older version of the book, split into six volumes: Newtonian Physics, Conservation Laws, Vibrations and Waves, Electricity and Magnetism, Optics, and The Modern Revolution in Physics. "

Spearfishing - no tanks, just holds his breath

In Crazy Plant Shop, students learn about plant genetics by taking on the role of a budding (pun intended) young botanist who operates a plant shop that specializes in rare and exotic breeds of plants! "

"Cheetahs are the fastest runners on the planet. Combining the resources of National Geographic and the Cincinnati Zoo, and drawing on the skills of an incredible crew, we documented these amazing cats in a way that's never been done before. Using a Phantom camera filming at 1200 frames per second while zooming beside a sprinting cheetah, the team captured every nuance of the cat's movement as it reached top speeds of 60+ miles per hour."

"Agricultural engineering is the discipline of engineering in agricultural, food, and biological systems. Agricultural engineers design agricultural machinery and equipment and agricultural structures. Some specialties include power system and machinery design; structures and environment; and food and bioprocess engineering. They develop ways to conserve soil and water and to improve the processing of agricultural products. Agricultural engineers work in research and development, production, sales, or management. "

"The Macaulay Library is the world's largest and oldest scientific archive of biodiversity audio and video recordings"

loons on Mason Lake and a chorus of birds in Queensland, Australia, thanks to this Mashable link to the free natural sounds archive, now available online from the Macaulay Library at the Cornell Lab of Ornithology. As Open Culture reports, the recordings go back to 1929.

"Materials Science and Engineering major, with concentrations offered in Biomaterials and Nanotechnology. As expected, the program provided a solid grounding in what materials science really is. Students explore materials from the atomic level all the way through crystal structures, multiphase systems, and bulk properties. You'll have an opportunity to learn why objects' matter matters. You'll explore the details of why glass shatters, metal bends, and rubber bounces back-and that's just in one class on mechanical properties. If you're more interested in how the circuits in your computer are fabricated, or why hip replacements are made of titanium instead of aluminum, you won't even have to go looking for courses in other departments. Materials Science is one of the most fundamental, and therefore most interdisciplinary, fields that exists today. In many core classes, you'll find more students from other majors than from the department itself."

"An elephant's hairs help heat travel away from the skin. According to the study, a light breeze is enough to significantly cool an elephant, increasing its heat loss by 20 per cent. Elephants, big leathery animals that they are, need to know how to cool off. They also use their trunks to splash water and mud on themselves."

"BatsLIVE: A Distance Learning Adventure is an exciting, free education program for children in the 4-8th grades and their educators, that will bring bat conservation to life in your classroom or community."

"Below you see a rotating array of blue crosses and 3 yellow dots. Now fixate on the centre (watch the flashing green spot). Note that the yellow spots disappear once in a while: singly, in pairs or all three simultaneously. In reality, the 3 yellow spots are continuously present, honest!"
