For those of you who might be skeptical, great! A right circular prismatic kiddie pool is only $10 and you can do the experiment for yourself at your latitude. There's really no reason you shouldn't do it for yourself.

We used two songs from other artists (licensed of course). Derek split the first one up so it fades from video to video, and Gordon split the instruments up on the second one. There are violins on one video and percussion on the other for example. It's really neat. The neat earth animation at the beginning and the synchronizing timer was made by http://eisenfeuer.com/. He also made still images of the earth from the top and the bottom. Thanks to Vanessa for filming in Sydney: http://youtube.com/braincraftvideo MORE INFO: There was a study performed at MIT years ago (http://web.mit.edu/hml/ncfmf/09VOR.pdf) that explained the physics involved. We repeated some of these demonstrations, but on opposite sides of the globe…and in a way that can be easily understood.

At the heart of the Milky Way, there's a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close -- even light. We can't see it, but its event horizon casts a shadow, and an image of that shadow could help answer some important questions about the universe. Scientists used to think that making such an image would require a telescope the size of Earth -- until Katie Bouman and a team of astronomers came up with a clever alternative. Bouman explains how we can take a picture of the ultimate dark using the Event Horizon Telescope.

Quantum Mechanics (Chapter 1): A Brief History Of Quantum Mechanics. --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- 1. A Brief History Of Quantum Mechanics http://www.youtube.com/watch?v=B7pACq_xWyw 2. The Structure Of Atoms http://www.youtube.com/watch?v=-YYBCNQnYNM 3. Wave Function And Wave-Particle Duality http://www.youtube.com/watch?v=7GTCus7KTb0 4. The Uncertainty Principle http://www.youtube.com/watch?v=Fw6dI7cguCg 5. The Spin Of Fundamental Particles 6. Quantum Entanglement --- The history of quantum mechanics began essentially with the 1838 discovery of cathode rays by Michael Faraday, the 1859 statement of the black body radiation problem by Gustav Kirchhoff, the 1877 suggestion by Ludwig Boltzmann that the energy states of a physical system could be discrete, and the 1900 quantum hypothesis by Max Planck that any energy is radiated and absorbed in quantities divisible by discrete energy elements, E, such that each of these energy elements is proportional to the frequency ν with which they each individually radiate energy. Planck insisted that this was simply an aspect of the processes of absorption and emission of radiation and had nothing to do with the physical reality of the radiation itself. However, at that time, this appeared not to explain the photoelectric effect (1839), i.e. that shining light on certain materials can function to eject electrons from the material. In 1905, basing his work on Plancks quantum hypothesis, Albert Einstein postulated that light itself consists of individual quanta. These later came to be called photons (1926). From Einstein's simple postulation was born a flurry of debating, theorizing and testing, and thus, the entire field of quantum physics. • http://en.wikipedia.org/wiki/Quantum_mechanics#History --- Quantum mechanics (QM) is a set of principles describing the physical reality at the atomic level of matter (molecules and atoms) and the subatomic (electrons, protons, and even smaller particles). These descriptions include the simultaneous wave-like and particle-like behavior of both matter and radiation ("waveparticle duality"). Quantum Mechanics is a mathematical description of reality, like any scientific model. Some of its predictions and implications go against the "common sense" of how humans see a set of bodies (a system) behave. This isn't necessarily a failure of Quantum mechanics - it's more of a reflection of how humans understand space and time on larger scales (e.g., centimetres, seconds) rather than much smaller. Quantum mechanics says that the most complete description of a system is its wavefunction, which is just a number varying between time and place. One can derive things from the wavefunction, such as the position of a particle, or its momentum. Yet the wavefunction describes probabilities, and some physical quantities which classical physics would assume are both fully defined together simultaneously for a system are not simultaneously given definite values in Quantum mechanics. It is not that the experimental equipment is not precise enough - the two quantities in question just are not defined at the same time by the Universe. For instance, location and velocity do not exist simultaneously for a body (this is called the Heisenberg uncertainty principle) Certain systems, however, do exhibit quantum mechanical effects on a larger scale; superfluidity (the frictionless flow of a liquid at temperatures near absolute zero) is one well-known example. Quantum theory also provides accurate descriptions for many previously unexplained phenomena such as black body radiation and the stability of electron orbitals. It has also given insight into the workings of many different biological systems, including smell receptors and protein structures. Even so, classical physics often can be a good approximation to results otherwise obtained by quantum physics, typically in circumstances with large numbers of particles or large quantum numbers. (However, some open questions remain in the field of quantum chaos.) • http://en.wikipedia.org/wiki/Quantum_mechanics .

Introduction to what a reference frame is.

How turbulent convection currents in Earth's outer core make its magnetic field This video is a prequel to one that will appear here: http://ve42.co/Spin Huge thank you to Prof. Jon Aurnou who spent a lot of time explaining how planetary magnetic fields are created. He changed a lot of my preconceptions. His youtube channel is here: https://www.youtube.com/user/spinlabucla His research page is here: http://ve42.co/SpinLab OK, so what were my preconceptions? 1. That the Earth's magnetic field is a passive thing - it shouldn't need a continuous input of energy to maintain itself (that seemed reasonable to me because the magnetic field has been around for a long time and it seems mostly stable). But as it turns out, the Earth is a giant electromagnet, and so of course those currents dissipate their energy as they encounter resistance in the liquid metal through which they flow. So the energy to continuously create these currents comes from the kinetic energy of the liquid metal flows in the Earth's outer core. 2. If it's convection, I'm thinking hot things rising, cooler things falling. But apparently the main effect driving convection is the compositional differences at the boundary with the Earth's inner core. This is because of the differential freezing at the boundary. Things like iron freeze into the inner core, while elements like sulfur do not. Hence the pockets of lighter material which then rise outwards. 3. I didn't get why the fluid motion was necessary for the generation of the magnetic field. I mean if it's a conducting liquid, it can conduct currents whether it moves or not. But the key is that the liquid metal can 'trap' magnetic fields. I imagine this like how iron channels magnetic fields. Then once these fields are channeled, they can be pulled and stretched, making more magnetic field. 4. Fluids operate very differently in rotating frames of reference. This is something I didn't intuitively grasp. But, as fluids move from the inner core outwards, those particles are moving much more slowly in the direction of rotation than the matter that has been there for a long time, which means the convection currents get deflected and form helices. Listening to Prof. Arnou's explanation made possible my explanation in the other video (it's really just a summary of what he says here). So thanks Prof. Arnou!

Este vídeo presenta la modulación de frecuencia (FM) y la compara con la modulación de amplitud (AM). Se hace constancia en lo que supone la desviación de frecuencia respecto a la amplitud de la señal moduladora. Por otra parte se presenta el desarrollo matemático de la modulación de frecuencia (FM) Por último se citan las características de FM: Mejora respecto al ruido en referencia con al AM Mayor ancho de banda transmitido
