post clockThe clock tower is usually part of a church or municipal building such as a town hall, but many clock towers are free-standing.

The mechanism inside the tower is known as a turret clock. It often marks the hour (and sometimes segments of an hour) by sounding large bells or chimes, sometimes playing simple musical phrases or tunes.

The Secret Life of Chaos

secrets of chaos

Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand.

It turns out that chaos theory answers a question that mankind has asked for millennia – how did we get here?

In this documentary, Professor Jim Al-Khalili sets out to uncover one of the great mysteries of science – how does a universe that starts off as dust end up with intelligent life? How does order emerge from disorder?

It’s a mindbending, counterintuitive and for many people a deeply troubling idea. But Professor Al-Khalili reveals the science behind much of beauty and structure in the natural world and discovers that far from it being magic or an act of God, it is in fact an intrinsic part of the laws of physics. Amazingly, it turns out that the mathematics of chaos can explain how and why the universe creates exquisite order and pattern.

And the best thing is that one doesn’t need to be a scientist to understand it. The natural world is full of awe-inspiring examples of the way nature transforms simplicity into complexity. From trees to clouds to humans – after watching this film you’ll never be able to look at the world in the same way again.

Ultimately, the ageing process itself could be slowed down or even halted. But what impact will this have on who we are and how we will live? And, with our mastery of the genome, will the human race end up in a world divided by genetic apartheid?

waste=food
Man is the only creature that produces landfills. Natural resources are being depleted on a rapid scale while production and consumption are rising in na tions like China and India. The waste production world wide is enormous and if we do not do anything we will soon have turned all our resources into one big messy landfill. But there is hope. The German chemist, Michael Braungart, and the American designer-architect William McDonough are fundamentally changing the way we produce and build. If waste would become food for the biosphere or the technosphere (all the technical products we make), produc tion and consumption could become beneficial for the planet.

A design and production concept that they call Cradle to Cradle. A concept that is seen as the next industrial revolution.

• Design every product in such a way that at the end of its lifecycle the component materials become a new resource.

• Design buildings in such a way that they produce energy and become a friend to the environment.

Large companies like Ford and Nike are working with McDonough and Braun gart to change their production facilities and their products. They realize that economically seen waste is destruction of capital. You make something with no value. Based on their ideas the Chinese government is working towards a circular economy where Waste = Food. An amazing story that will definitely change your way of thinking about production and consumption.

megacities

Megacities takes a revolutionary look at the places where most of us live: the modern Metropolis. Megacities focuses on the single aspect of a city’s infrastructure which best informs the life and functions of that place. Each city is examined as an organism: living, breathing, and growing. In order to survive, these infrastructures must each function independently, and yet blend into a harmony of man, machine, strategy and system, which defines it as a mega city. Megacities examines the infrastructure of eight iconic locations around the world: Las Vegas, Mexico City, Hong Kong, London, Paris, Sao Paulo, Mumbai and New York. Through dramatic storytelling, unparalleled access and sophisticated computer graphics blended seamlessly with live action, Megacities takes viewers beyond the monuments – and into the machinery – that is the true, living marvel of each mega city.

Six Degrees Of Separation

Refers to the idea that, if a person is one step away from each person they know and two steps away from each person who is known by one of the people they know, then everyone is at most six steps away from any other person on Earth.

Its a profound theory that could lead to us being connected somehow to everyone on earth.

Six Degrees Of Separation

100 Greatest Discoveries

Part 1

Part 2

Part 3

Part 4

Part 5

1. The Law of Falling Bodies (1604)
Galileo Galilei overturns nearly 2,000 years of Aristotelian belief that heavier bodies fall faster than lighter ones by proving that all bodies fall at the same rate.

2. Universal Gravitation (1666)
Isaac Newton comes to the conclusion that all objects in the universe, from apples to planets, exert gravitational attraction on each other.

3. Laws of Motion (1687)
Isaac Newton changes our understanding of the universe by formulating three laws to describe the movement of objects. 1) An object in motion remains in motion unless an external force is applied to it. 2) The relationship between an object’s mass (m), its acceleration (a) and the applied force (F) is F = ma. 3) For every action there is an equal and opposite reaction.

4. The Second Law of Thermodynamics (1824 – 1850)
Scientists working to improve the efficiency of steam engines develop an understanding of the conversion of heat into work. They learn that the flow of heat from higher to lower temperatures is what drives a steam engine, likening the process to the flow of water that turns a mill wheel. Their work leads to three principles: heat flows spontaneously from a hot to a cold body; heat cannot be completely converted into other forms of energy; and systems become more disorganized over time.

5. Electromagnetism (1807 – 1873)
Pioneering experiments uncover the relationship between electricity and magnetism and lead to a set of equations that express the basic laws governing them. One of those experiments unexpectedly yields results in a classroom. In 1820, Danish physicist Hans Christian Oersted is speaking to students about the possibility that electricity and magnetism are related. During the lecture, an experiment demonstrates the veracity of his theory in front of the whole class.

6. Special Relativity (1905)
Albert Einstein overthrows basic assumptions about time and space by describing how clocks tick slower and distances appear to stretch as objects approach the speed of light.

7. E = mc^2 (1905)
Or energy is equal to mass times the speed of light squared. Albert Einstein’s famous formula proves that mass and energy are different manifestations of the same thing, and that a very small amount of mass can be converted into a very large amount of energy. One profound implication of his discovery is that no object with mass can ever go faster than the speed of light.

8. The Quantum Leap (1900 – 1935)
To describe the behavior of subatomic particles, a new set of natural laws is developed by Max Planck, Albert Einstein, Werner Heisenberg and Erwin Schrodinger. A quantum leap is defined as the change of an electron within an atom from one energy state to another. This change happens all at once, not gradually.

9. The Nature of Light (1704 – 1905)
Thought and experimentation by Isaac Newton, Thomas Young and Albert Einstein lead to an understanding of what light is, how it behaves, and how it is transmitted. Newton uses a prism to split white light into its constituent colors and another prism to mix the colors into white light, proving that colored light mixed together makes white light. Young establishes that light is a wave and that wavelength determines color. Finally, Einstein recognizes that light always travels at a constant speed, no matter the speed of the measurer.

10. The Neutron (1935)
James Chadwick discovers neutrons, which, together with protons and electrons comprise the atom. This finding dramatically changes the atomic model and accelerates discoveries in atomic physics.

11. Superconductors (1911 – 1986)
The unexpected discovery that some materials have no resistance to the flow of electricity promises to revolutionize industry and technology. Superconductivity occurs in a wide variety of materials, including simple elements like tin and aluminum, various metallic alloys and certain ceramic compounds.

12. Quarks (1962)
Murray Gell-Mann proposes the existence of fundamental particles that combine to form composite objects such as protons and neutrons. A quark has both an electric and a “strong” charge. Protons and neutrons each contain three quarks.

13. Nuclear Forces (1666 – 1957)
Discoveries of the basic forces at work on the subatomic level lead to the realization that all interactions in the universe are the result of four fundamental forces of nature — the strong and weak nuclear forces, the electromagnetic force and gravitation.

Chances are you’ve seen one and you just didn’t realize it. Fractals are most recognized as a series of circular shapes with a border surrounded by jagged “tail-like” objects. NOVA’s episode, “Fractals: Hunting the Hidden Dimension” is a quite interesting fifty minute look at the topic.

The program, aimed at the average viewer does a fine job of explaining the background of fractals, first by beginning with the story of Pixar co-founder, Loren Carpenter’s work at Boeing, developing 3D terrain from scratch using fractals. From there the program starts at the beginning with an introduction to Benoit Mandelbrot and his revolutionary work. The explanations are full of solid factual information but never talk above the level of a viewer who has some understanding of basic mathematical principles. Once the concept is presented the program spends the rest of the time showing how prevalent the fractal is in life.

For a program about a mathematical concept, “Fractals” is very engaging, showing how the process was applied to special effects as far back as the Genesis planet from “Star Trek II” all the way to the spectacular finale on Mustafar in “Star Wars: Episode III.” I found myself astonished at how fractals were the source of the lava in constant motion and action during the Obi-Wan/Anakin fight. What is more amazing is when the program delves into practical applications such as cell phone antennas, and eventually the human body.

For the average person who enjoys watching NOVA or other science related programs, even on a sporadic basis, “Fractals” will prove to be a very worthwhile experience. The program is well produced, integrating talking head interviews (including some with Mandelbrot himself) with standard “in the field” footage. The structure of the program is very logical and never finds itself jumping around without direction. In simplest terms, this is a program as elegant as the designs it focuses on.

Einstein's Life

Part 1: Einstein’s Unfinished Symphony

The story of who Einstein was and how he lived. The dawn of the new century brought many great discoveries, among them was his most famous E=mc² which life measurable of not predictable. He predicted how the speed of light would be constant rather that time. This had revolutionised science forever but then came along the the theory of relativity which predicted the unmeasurable states of the atom. This new idea did not “sound right” to Einstein and his stubborness to accept it meant that he spent a good part of his life trying to proove otherwise. (Full Program Summary: BBC-Horizons)

Part 2: Einstein’s Equation of Life and Death

Story About how one of the most famous equations E=mc² became the equation of life (generate nuclear power) and death (Hiroshima). As Albert Einstein wrote a letter of warning to the then president of USA Roosevelt, he did not realize that his letter would not only warn the world of the danger ahead, but also inspire then to device it.   (Program Summary: BBC-Horizons)

Nova- Secrets of The Mind

Secrets Of The MindIf you are the least bit curious on how the mind works and the infinite mysteries that it holds then this documentary is for you. Some of the fascinating things that scientists, psychologists and physcians have discovered about the inner workings of the brain is unfortunately the result of brain injured patients.

There are people in this world who have profoundly different experiences of reality than you and I have. People who can see whilst being blind, who can feel pain in amputated limbs, who believe they are God , and even people who think their own parents are imposters.

These people may be called crazy, but they’re not. Their ways of thinking are limited and distorted because some parts of their brains have suffered physical damage. Today neuroscientists like Ramachandran investigate their brains and their unique make up to discover the Secrets Of The Mind.
