MiG-31: The Near-Space Plane. Russia’s super-fast interceptor


Published on Sep 30, 2018

Watch Combat Approved series: https://rtd.rt.com/series/combat-appr… Imagine flying a plane so high that the world looks spherical and the sky is pitch-black. The Mikoyan Mig-31 fighter is the only jet plane in the world to make it possible to fly on the very edge of space. With an incredible speed of 3,000 km/h, the Soviet-designed interceptor is the world’s fastest serving aircraft, and it can fly twice as high as a commercial flight. Travelling at more than twice the speed of sound, the MiG-31 can touch the stratosphere and breach what’s known as the Armstrong limit. beyond which a pilot’s tears and saliva would boil without a pressure suit. Even at such incredible heights, the MiG-31 can still deal with its enemies. The fighter is armed with long and short-range missiles that can be launched against high-speed targets. At Khotilovo air base, RTD attempts to give viewers a first-hand experience of near-space travel aboard this unique aircraft by mounting cameras on the airframe and inside the cockpit. See what breaking the sound barrier looks like and why, despite being designed in the 1970s, the MiG-31remains at the top of its game and unrivalled to this day.

Is SpaceX’s Raptor engine the king of rocket engines?


Published on May 25, 2019

2:55 – Basic physics of rocket engines 6:10 – Rocket engine cycles 20:30 – Rocket fuel comparison 30:40 – Raptor vs other rocket engines 44:05 – Summary Article version – https://everydayastronaut.com/?p=9823… SpaceX’s new raptor engine is a methane fueled full flow staged combustion cycle engine and its so hard to develop, no engine like this has ever flown before! Now this topic can be really intimidating so in order to bring the Raptor engine into context, we’re going to do an overview of a few common types of rocket engine cycles then compare the Raptor to a few other common rocket engines, like SpaceX’s current work horse, the Merlin, The Space Shuttle’s RS-25, the RD-180, Blue Origin’s BE-4 and the F-1 engine. And if that’s not enough, not only is SpaceX using a crazy engine cycle, they’re also going to be using Liquid Methane as their fuel, again something that no orbital rocket has ever used! So we’ll also go over the unique characteristics of liquid methane as a rocket fuel and see if we can figure out why SpaceX went with Methane for the Raptor engine. We’ll also break down and explain all the different engine cycle types so you know what the full flow staged combustion cycle is, how it works, and how it compares to the other cycles. So by the end of this video hopefully we’ll have the context to know why the raptor engine is special, how it compares to other rocket engines, why it’s using methane and hopefully find out if the Raptor engine will be the new king of rocket engines… ———————————————– Rocket engine renders by @MartianDays https://twitter.com/MartianDays HUGE thanks to my Moon Walker Patreon supporters!

Economic Freedom of the World | Learn Liberty


Published on Sep 7, 2011

Do you prefer the world of Adam Smith or the world of Karl Marx? Prof. Robert Lawson tells the story of his numerous discussions about this very question with his friends in college. Even after years of theoretical discussion with his friends, a conclusion was never reached between them. Prof. Robert Lawson now works on the Economic Freedom of the World project, which is an empirical study that attempts to answer this same question. In order to do this, the study compares data related to economic freedom and quality of life. It finds that countries with institutions resembling those advocated by Adam Smith tend to provide the highest quality of life to its citizens. The latest edition of the Economic Freedom of the World report can be found here: http://www.freetheworld.com/release.html

BIS – The Central Bank of Central Banks


 

QUESTION: Could you please tell us more about the bank of the national banks (BIS) located in Swiss?
Many thanks for your information. I love to read your blog first thing in the morning!!!

JS

ANSWER: The Bank for International Settlements (BIS) was originally established to handle the reparation payments of Germany. It was also supposed to facilitate cooperation among the central banks. However, it had no real power to compel them to do anything, which was demonstrated by France who refused to agree with the other member concerning the reparation payments of Germany. The BIS was created in 1930 at the Hague Conference. A convention respecting the establishment of the BIS was signed between Belgium, France, Germany, Italy, Japan and the United Kingdom on the one hand, and Switzerland on the other. The BIS is owned by 60 central banks, representing countries from around the world that together account for about 95% of world GDP. It is the central bank for central banks.

The BIS does have a full range of traditional short-term instruments, denominated in reserve currencies. The BIS instruments allow customers to meet cash management objectives. They also provide tradeable instruments that are widely used by reserve managers seeking credit quality, which they will issue in major currencies along the yield curve. The paper is 1 to 5 years in maturity.

When Will Interest Rates Rise?


QUESTION: In the recent past you have spoken about rising interest rates in the USA being imminent. Just wondering where we stand on that front as rates have been in a downtrend since peaking last fall?

Thanks,

Pete

ANSWER: The rise in interest rates comes with the turn in the ECM in January. However, what you have to understand is there will be a divergence between private and public rates. The central banks really cannot raise rates without creating a budget crisis. The more likely outcome is that governments are losing their ability to borrow in the real market. The public rates are more likely to become simply pegs that render them useless in all practical terms. We have already witnessed this in Europe. The central bank created negative interest rates. All they have done is to kill the viable domestic bond markets.
