1 The incredible shrinking chip Two Scottish computer engineers with little or no physics knowledge set out to make a semiconductor transistor. This was 50 years ago, and their efforts gained them the Nobel Prize. The versatility of that transistor is now at the heart of the electronics industry. Millions of transistor switches are shrunk down into the microprocessors that are found in computers, mobile phones and almost everything else electrical. The first transistor took years to plan and make; today more are made

The most ‘important and greatest puzzle’ we face as humans is ourselves (Boring, 1950, p. 56). Humans are a puzzle – one that is complex, subtle and multi-layered, and it gets even more complicated as we evolve over time and change in different contexts. When answering the question ‘What makes us who we are?’, psychologists put forward a range of explanations about why people feel, think and behave the way they do. Just when psychologists seem to understand one bit of ‘who we are’
Introduction to Christian Studies
In this lecture, we will explain the Christian Studies totally as the comprehensive studies of Christianity, which includes theology, philosophy of religion, and modern studies of religion.
Motion in the R-Aquarii Jet 1991, 1992, 1993: Image Deconvolution of 1992 Data
Images from the Hubble Space Telescopes Faint Object Camera from 1991, 1992, and 1993 demonstrate motion in the R Aguarii emission jet. Since images from this period were still affected by the primary mirror flaw, the images were restored to the original design resolution using the maximum entropy method.

How to Determine the Mean
This is a brief how-to video on how to determine the mean (average) that will improve your math skills. The instructor starts out with an easy problem, then moves on to a more complex problem. (05:49)
Digital Storytelling in the Classroom
This 2:44 long video explains how an experienced social studies teacher started to use Digital Storytelling to engage her students in the classroom. There is little hands on examples and most of the information does not offer how the student work is evaluated or how it has improved their understanding of the topic.
An introduction to electromagnetic induction for students studying for International Bacc., but also useful for other students on higher-level courses. The presentation is supported by many experimental demonstration including the dynamo and motor effects, Faraday's Law and magnetic flux. (16:33)
