Myths v Reality – Milton Friedman


Universal Basic Income


The idea of some Universal Basic Income has been around for a long time. Here is Milton Friedman on his proposal of a Negative Income Tax. There will always be welfare for there are people who cannot work for some disability and others who prefer not to work and game the system. Even programs where the state directly pays for the food rather than food stamps or restricts the food stamps to certain products, the ingenuity of some people cannot be underestimated. They will sell the products they get for cash. There are signs on the streets buying needles and strips from people who are diabetic and get them for free from the state. There are instances where a woman has a child and tells the state she has no idea who the father is yet a night he shows up and leaves when a case worker is due to arrive. These are abuses of the system that no matter what we try to do, there will be people who figure out how to work the system. So there will NEVER be 100% compliance no matter what system we devise.

Apollo 11 Saturn V Launch Camera E-8


Published on Apr 7, 2013

This clip is raw from Camera E-8 on the launch umbilical tower/mobile launch program of Apollo 11, July 16, 1969. This is an HD transfer from the 16mm original. Even more excellent footage is available on our DVDs at our website at http://www.spacecraftfilms.com The camera is running at 500 fps, making the total clip of over 8 minutes represent just 30 seconds of actual time.

Reaction Wheels – Things Kerbal Space Program Doesn’t Teach


Published on Jul 9, 2016

Reaction wheels in Kerbal Space Program might actually refer to a number of different technologies used to control the attitude of spacecraft. Let’s go into some detail about these.

How Gravity Assists Work


Published on Sep 25, 2017

Time to clear up some misconceptions and show how a spacecraft’s close encounter with a planet can change a spacecraft’s orbit and enable trajectories beyond its available delta-v. I specifically cover some of the math and look at the unusual trajectory employed by the OSIRIS REx mission.

Geostationary, Molniya, Tundra, Polar & Sun Synchronous Orbits Explained

Illustrating different classes of orbits commonly used by satellites in Earth orbit, there are special classes of orbit designed to solve certain problems and the physics behind them is important. All the orbits are displayed using Universe Sandbox 2. Buy it here: https://www.humblebundle.com/store/un…

Heat Shields – Things Kerbal Space Program Doesn’t Teach


Published on Dec 29, 2018

The science of Aerothermodynamics covers what happens during a spacecraft’s fiery flight through a planetary atmosphere as it sheds speed, converting kinetic energy into thermal energy. This represents a complex interaction between fluid mechanics, thermal radiation and chemistry. The engineering required to shield hardware against this intense heating is an equally complex multi disciplinary art. If you want to learn the math then this course offered an excellent overview: https://tfaws.nasa.gov/TFAWS12/Procee…

Graveyard Orbits Where Old Satellites Are Forgotten

When a satellite is designed these days it’s also important to think about what happens at the end of its lifetime, for more LEO satellites they’ll happily decay and fall into the atmosphere on their own. But there are many cases where this can’t happen, either because the spacecraft doesn’t have the fuel, or because the satellite is dangerous. For these, there’s a retirement home in the graveyard orbit.

Manipulating the World Economy will be also available in Russian, German, and Chinese


We are looking at having it Translated into several languages. We hope this English version will be available by October in hardbound. I really hope this will help change the debate for what lies at stake is the future for us, but more so our posterity.
