A semi deep zoom into a Julia fractal (around e^-68 I think). As will be seen near the end the seemingly connected structure becomes two parts, and thereby the “seed” for this Julia fractal is outside the Mandelbrot (fractal), it is then a dust fractal. The solid structure is made of increasingly smaller self similar shapes (an infinity amount of them), which all together makes the fractal look as a whole (which it isn’t). The zoom is at the origon of the Julia fractal as this is the place that is known to show if the fractal is connected (in or on the Mandelbrot) or disconnected (dust fractal and outside the Mandelbrot). An interesting aspect of the Julia fractal is that the precision needed increases towards the centre (as concentric circles) at any given zoom factor. It is then possible to speed up the calculations of the whole plane by adjusting the precision as an variation from the origon. The trick wasn’t used in the animation as it was used to gather the information about this observation. Due to the “deepness” of this zoom, regular floating point numbers wasn’t enough and bignum was used, the final stage of the fractal used 768 bit. At the start regular 64 bit was used (on 64bit single core AMD CPU running Debian 64bit Linux). Total render time about 500 hours.

richarddawkins.net Oxford professor Richard Dawkins presents a series of lectures on life, the universe, and our place in it. With brilliance and clarity, Dawkins unravels an educational gem that will mesmerize young and old alike. Illuminating demonstrations, wildlife, virtual reality, and special guests (including Douglas Adams) all combine to make this collection a timeless classic. The Royal Institution Christmas Lectures for Children were founded by Michael Faraday in 1825, with himself as the inaugural lecturer. The 1991 lecturer was Richard Dawkins whose five one-hour lectures, originally televised by the BBC, are now available free online, courtesy of The Richard Dawkins Foundation for Reason and Science. The entire 5-hour program is also available on a 2-DVD set through our online store. richarddawkins.net The DVD includes subtitles in English, Spanish, French and Polish. Read the transcript: richarddawkins.net If you enjoy these free videos, please consider purchasing the DVD and/or making a donation to The Richard Dawkins Foundation for Reason and Science to help us continue our work.

Lecture in mathematics at MIT

This video was uploaded with the written permission of Gresham College. • The Empiricist Turn, Part 3 of 6 • Date/Time: 14/02/2008 Speaker: Professor Keith Ward. Professor Ward has a BA from the University of Wales, an MA from the University of Cambridge, an MA and B Litt from the University of Oxford, a DD from Cambridge and a DD from Oxford. This lecture is about Hume and the grounding of knowledge in human experience, the conflict of reason and common sense. The lecturer raises a thought-provoking question: Hume was wrong about science – was he wrong about religion too? For more information, other lectures, transcripts, downloadable audio and video.

This lecture gently introduces the idea of a “surface integral” and illustrates how to integral functions over surfaces. The idea is a generalization of double integrals in the plane. The concept of surface integral has a number of important applications such as caculating surface area. In addition, surface integrals find use when calculating the mass of a surface like a cone or bowl. A number of examples are presented to illustrate the ideas. Such concepts are seen in 2nd-year university mathematics courses.

Part 6 of “Cradles of Civilization: Lecture 2″. Dr. Neiman reviews Babylonian advances in astronomy and mathematics. He also credits the Babylonians with devising some of civilization’s most basic concepts: dividing the circle into 360 degrees, the day into 24 hours and the hour into 60 minutes. Dr. David Neiman (1921-2004) was an internationally renowned scholar, speaker, and writer who inspired many people. His life’s work concerned the intricate relations between Christianity, Islam, and Judaism throughout history and in modern times. Dr. Neiman made history come alive through his dramatic presentations and unique interpretations. In light of our current world situation, Dr. Neiman’s work is not only extremely relevant but also remarkably prescient. More than anything, Dr. Neiman was a keen observer of the human condition. His words convey our shared history with clarity, humor, and humanity. Dr. Neiman was the first Jewish scholar appointed to teach Religion at Boston College, one of America’s leading Catholic Universities. He served as Professor in the Department of Theology for a quarter of a century. While there he was also invited to teach at the Pontifical Gregorian University in Rome. After retiring from Boston College, Dr.Neiman moved to Los Angeles, where he taught at Loyola Marymount University, St. John’ s Seminary in Camarillo and the University of Judaism in Bel Air.

Column Chromatography It takes considerable practice to master the art of “running a column”. This video will get you started, with tips on picking appropriate conditions, packing and running a column, monitoring separation, and even making a micro-column from a pipet.

A new medical field that will allow doctors to examine a person’s genetic profile to determine which medicines will work best.

The problem Matt Damon’s character solved in ‘Good Will Hunting’ – Homeomorphically Irreducible Trees of degree ten. The problem sounds complex but is actually very easy.Robin Wilson, Gresham Professor of Geometry, explains the problem and shows the simple solutions. This is the 21st part of ‘A Millennium of Mathematical Puzzles’. The full lecture is available (in 24 parts) here on youtube, or it can be downloaded (like all of our lectures) in its complete form from the Gresham College website, in video, audio or text formats: www.gresham.ac.uk Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website.

As part of the 2009 Discovery Lecture – An Evolution Doubleheader. Dr. Charles Goodnight (University of Vermont) Dr. Goodnight will take us through a journey of the four forces of evolution: selection, drift, migration and mutation. He will illustrate how inheritance can include complex genetic interactions, or non-genetic factors such as culture; and why selection can occur at nearly any level of organization. www.carleton.ca

I present an example where I calculate the line integral of a given vector function over a closed curve.. In particular, I the vector function is a $${\bf F}(x,y) := (-y/(x^2 + y^2), x/(x^2 + y^2)$$ and the closed curve is the unit circle, oriented in the anticlockwise direction. I solve the problem and discuss the significance of the line integral through the mention of specific applications to engineering and physics. Such an example is seen in second year university mathematics.
