Having the umpire tossed from the game, and letting a computer call balls and strikes seems like a very 2019 thing to do. After all, every fan watching TV can see how often the ump is wrong. But Bill Whittle and Stephen Green tell Scott Ott a robot ump is a major league mistake.

Artificial gravity is a concept that is ubiquitous in our science fiction yet elusive in our space program. Why is this? And how could we develop artificial gravity soon? In a Cool Worlds special, this video essay goes in depth on the topic discussing why centrifuges are the most plausible solution and early ideas on the topic. Join us a journey from Einstein’s equivalence principle, to O’Neill Cylinders and Stanford Tori; from Coriolis forces to near-term experiments. Grab a cup of a tea and enjoy.

Why have SpaceX, Boeing & Blue Origin ditched abort towers?

Want an article version of this video? Here you go! https://everydayastronaut.com/abort-t… There’s a new trend going around in the commercial space industry when it comes to launch abort systems. All three commercial companies who are putting abort systems on their crewed vehicles have ditched the classic launch abort tower we’ve seen dominate abort systems in the past. Previous vehicles like the Mercury capsule, the Apollo capsule and even the Soyuz all used an escape tower that sat on top of the crew module, capable of pulling the vehicle away from a failing rocket in a hurry. And to make this topic even more interesting, we’re seeing another trend in abort systems… SpaceX’s Crew Dragon and Boeing’s Starliner capsules both are using liquid fueled abort motors instead of solid rocket motors. So today we’re going to talk about the design considerations that have made SpaceX, Boeing and Blue Origin ditch abort towers on their crewed vehicles and we’re also going to evaluate why the heck Boeing and SpaceX are going with liquid motors instead of solid motors. And with both Boeing and SpaceX having experienced serious setbacks and complications with their liquid fueled abort systems, including the loss of a test vehicle, it raises the question… is it even a good idea?….

 

Are Two-Tier Monetary Systems a Possible Tool?


QUESTION: Mr. Armstrong; It seems few people even understand that there have been two-tier monetary systems. Do you think this can be a possible tool in the currency crisis you are forecasting for 2021?

Thank you;

Looking forward to Rome and meeting Mr, Farage as well

ANSWER: Various countries used to mint trade dollars in silver with different weights for external trade with China. That was a two-tier monetary system for trade during the 19th century. But there have been instances where there were two separate currencies that were also used as capital controls to isolate the domestic economy from the external international capital flows. This was the case with South Africa.

An important example of an official deliberate two-tier monetary system is the modern monetary history of South Africa. Until the late 1960s, South Africa had a fixed exchange rate for its currency. The rand was pegged to major foreign currencies, as was the case under the Bretton Woods system.

It was during 1979 when the South African government switched to a system that formally expressed parity against the dollar. The value of the rand followed changes in the balance of payments and moved roughly with sterling and other weaker currencies until 1985 when the dollar soared and the birth of the Plaza Accord took place.

The foreign debt crisis of 1985 caused the rand to depreciate at a spectacular rate and the dollar rose in value. The rand fell to an all-time low of less than 40 cents to the US$. The rand recovered somewhat in 1987, reaching 43 cents, but it declined steadily thereafter into 1998. The rand collapsed to about 26 cents against the US$ in late 1995. Between February 1, 1996 and May 1, 1996, the rand lost roughly 16% of its exchange value, falling from R3.7 to R4.33 = US$1, or a value of about 23 cents to the US$.

The government realized that its domestic policy objectives were incompatible with international investment. They then created a parallel currency to act as a two-tier currency unit they named the “Financial Rand.” This hybrid currency was used exclusively for the movement of nonresident capital during the 1980s and early 1990s. The Financial Rand developed out of currency-exchange controls instituted in the early 1960s, known as the “blocked rand.” The Financial Rand was available only to foreigners for investment in South Africa and was created by the sale of nonresidents’ assets in the country.

Therefore, South Africa created a formal two-tiered currency system, which insulated the country’s foreign reserves from politically motivated capital flight. Since any divestment by nonresidents was automatically met by new investment, and the price of the Financial Rand varied independently of the commercial rand, a stability was achieved.

The Financial Rand invariably stood at a discount to the commercial rand, but the size of the discount depended on South Africa’s relative attraction as an investment destination. The discount stood at almost 40% during most of 1992 during the political crisis. The Convention for a Democratic South Africa (CODESA) began in December 1991 at the Johannesburg World Trade Center, attended by 228 delegates from 19 political parties. Mandela remained a key figure and after de Klerk used the closing speech to condemn the ANC’s violence, he took to the stage to denounce de Klerk as the “head of an illegitimate, discredited minority regime”.

This confrontation caused the rand to collapse. CODESA 2 was held in May 1992, at which de Klerk insisted that post-apartheid South Africa must use a federal system with a rotating presidency to ensure the protection of ethnic minorities. Mandela opposed this idea and demanded a unitary system governed by majority rule. Following the Boipatong massacre of ANC activists, Mandela called off all negotiations, and called for a special session of the UN Security Council and proposed that a UN peacekeeping force be stationed in South Africa to prevent “state terrorism.” Calling for domestic mass action, in August the ANC organized the largest-ever strike in South African history, and supporters marched on Pretoria. The rand declined to about 20% by late 1993.

Reserve Bank governor Chris Stals, under pressure from the banking and business communities, said that the government would phase out the Financial Rand in 1994 or 1995, assuming that South Africa’s foreign currency reserves reached at least R20 billion and that the discount between the financial and the commercial rends narrowed to about 10%. Foreign currency reserves were low in early 1994 but thanks to a dramatic reversal of the capital outflow in 1993, foreign currency reserves increased throughout 1994 and into early 1995.

Finally, by March 1995, with foreign reserves of only about R12 billion, the government abolished the financial rand. The newly unified currency began to trade on international currency markets, marking a vote of confidence in South Africa’s business potential.

Only a two-tier currency system can possibly weather the economic storm on the horizon from the collapse of the European Union at the hand of this lethal combination of policies. The next banking crisis will most likely begin in the Eurozone due to a continued failure to resolve the systemic weaknesses of its construction. The failure to have consolidated the debts means that the failure on the state level will ripple through the entire European economy. In the United States, state debt is not used for reserves. The failure of California will only send bond seekers into the federal debt who are fleeing state and municipal debt. We see that in Europe as capital fled from most members concentrating in Germany, which is the US Treasury equivalent within the Eurozone. With the first bail-in under the BRRD agreement, the contagion will be devastating as was the case when Michigan closed its banks in 1933 in the USA.

The Financial Rand fell below the domestic commercial rand when the 1992 political crisis unfolded, and capital fled South Africa unwilling to invest in a nation that might move into civil war. The two-tier currency system can and does help to distinguish between domestic and international capital flows.

There is the potential to create a two-tier monetary system with a new type of international currency that is separate and distinct from that of the domestic currency. This would allow the US dollar to end its reserve status and end the clash between domestic and foreign policy objectives.
