Whales Give Dolphins a Lift
Science Bulletins: Many species interact in the wild, most often as predator and prey. But recent encounters between humpback whales and bottlenose dolphins reveal a playful side to interspecies interaction. In two different locations in Hawaii, scientists watched as dolphins “rode” the heads of whales: the whales lifted the dolphins up and out of the water, and then the dolphins slid back down. The two species seemed to cooperate in the activity, and neither displayed signs of
Physics in architecture
Developed in 1998 by Dr John Whittle (Department of the Built Environment) using Authorware, this package contains brief interactive notes on eight areas of physics in which architects need a working knowledge. However, it is also useful to others in science, engineering and social sciences looking for an introduction to the topics concerned. These topics are: Units of measurement; Scalar and vector quantities; Newton’s laws; Mass and weight; Action and reaction; Waves; Heat, work and energy;
3.052 Nanomechanics of Materials and Biomaterials (MIT)
This course focuses on the latest scientific developments and discoveries in the field of nanomechanics, the study of forces and motion on extremely tiny (10-9 m) areas of synthetic and biological materials and structures. At this level, mechanical properties are intimately related to chemistry, physics, and quantum mechanics. Most lectures will consist of a theoretical component that will then be compared to recent experimental data (case studies) in the literature. The course begins with a ser
Evolving board evaluation fuctions for a complex strategy game
The development of board evaluation functions for complex strategy games has been approached in a variety of ways. The analysis of game interactions is recognized as a valid analogy to common real-world problems, which often present difficulty in designing algorithms to solve them. Genetic programming, as a branch of evolutionary computation,provides advantages over traditional algorithms in solving these complex real-world problems in speed, robustness and flexibility. This thesis attempts to a
Jeff Gold Inaugural Lecture - The Leader's Conundrum or 'You cannot lift yourself up by your own shi
The aim of the lecture will be to do demonstrate the need to challenge continuing traditional images of leaders, often depicted at the apex of things, on top of a hill or at the centre of a complex web of activity. I will argue that those nominated as leaders MUST become aware of what I will call the leader's conundrum and complement their inspiration with 99 x perspiration. To appreciate this call, attendees to the lecture as respectfully asked to do the following just before the lecture: a.

7.343 Photosynthesis: Life from Light (MIT)
In this course, you will journey through the web of physical, chemical, and biological reactions that collectively constitute photosynthesis. We will begin with light harvesting and follow photons to the sites of primary photochemistry: the photoreaction centers. A molecular-scale view will show in atomic detail how these protein complexes capture and energize electrons. Then we will follow the multiple pathways electrons take as they carry out their work. Consequent reactions, such as the synth

Top 10 Tips For Peak Performance
Because an athlete's schedule is often so busy, good nutrition can often take a back seat. UW Medical Center Dietician, Alysun Deckert, provides 10 easy nutrition tips to help athletes stay on track and reach their peak performance.
Spherulite in poly-3-hydroxy butyrate (PHB)
Polymer melts often crystallise from heterogeneous nuclei to form ribbon-like lamellae, which have a folded chain molecular structure. They commonly radiate outwards from the nucleation point, to form spherical features called spherulites - which are often quite large. The characteristic Maltese cross pattern, seen when viewed between crossed polars, results from isoclinic fringes formed when one of the principal vibration directions is approximately parallel to the polariser. In some cases
