During a trip to the United States, the two sides argue furiously, and he is kidnapped and threatened with a gun. Freed and penniless, he travels to Las Vegas, where he wins $600 at the casino and spends it on a flight to a friend’s house in Seattle. At his friend’s house, he is put in touch with Amazon, a fledgling company. A quick browse of the site reveals that China isn’t covered. Jack Ma returns to China, drops out of college, and founds a startup: China Pages, which later becomes Alibaba in 1999, with participation from Yahoo! and the Japanese financial company SoftBank.

Nerve gas in the Tokyo subway. During the morning rush hour, fanatics from the Aum Shinrikyo religious sect converged on the Kasumigaseki station of the Tokyo subway and released a lethal gas, sarin, into the air. After taking an antidote, the terrorists fled, while passengers, blinded and gasping, ran toward the exits. Twelve people died, and over 5,000 were hospitalized, many in a coma. After the attack, police raided Aum Shinrikyo’s headquarters, arresting hundreds of followers, including leader Shoko Asahara. The sect, which practiced a blend of Buddhism, yoga, and Christian apocalyptic philosophy, was already under investigation for a similar attack in 1994 that had killed seven people, and for the assassinations of several political opponents.

The Banana Equivalent Radiation Dose is coined. Gary Mansfield writes to Radsafe, arguing that it is impossible to achieve zero radiation levels, since even bananas are radioactive, containing small doses of the highly radioactive isotope Potassium-40 (one of the radioactive components that heats the Earth’s core). The text of the email, which is worth reading in full, is: re: The Radiation Dose from a “Reference Banana.” Some time ago (when I almost had time to do such things), I calculated the dose one receives from the average banana. Here’s how it goes: On page 620 of the CRD Handbook on Rad Measurement and Protection, the concentration of K-40 in a “Reference Banana” is listed as 3520 picocuries per kilogram of banana. For those of us who are stuck in certain unit rules, this is equivalent to 3.52E-6 microcuries of K-40 per gram of banana. An average “Reference” banana weighs (masses) about 150 grams (I think.) So, the ICRP Reference Banana contains about 5.28E-4 microcuries of probably deadly K-40. Federal Guidance Report #11 lists the ingestion dose (committed effective dose equivalent) for K-40 as 5.02E-9 Sv/Bq or (again, for those of us who are “unit-challenged,” 1.86E-2 rem per microcurie ingested.) Thus, the CEDE from ingestion of a Reference Banana is 5.28E-4 x 1.86E-2 = 9.82E-6 rem or about 0.01 millirem. I have found this “Banana Equivalent Dose” very useful in attempting to explain infinitesmal doses (and corresponding infinitesmal risks) to members of the public. (Interestingly, the anti-nukes just HATE this, and severely criticize us for using such a deceptive concept.) Would love to go into more detail, but have to get back to our DEADLY Human Radiation Experiments (ie, eating bananas.) The same table in the CRC Handbook lists 3400 pCi/kg for white potatoes and 4450 pCi/kg for sweet potatoes – so you could carry through the same sort of calculation for Reference Potatoes. Interestingly, raw lima beans come in at 4640 pCi/kg, “dry, sweet” coconut comes in at 6400 pCi/kg, and raw spinach (yum!) comes in at 6500 pCi/kg. Considering the fact that the DOE has officially stated that “there is no safe dose of radiation” my advice to you all is to stop eating immediately. Oh yes! Almost forgot. Regarding K-40, go into your local grocery store, buy some salt-substitute (there are two common brands, and the one in the white and orange labeled container works best) spread some

At FermiLab, two teams of nearly 1,000 scientists (USA, Italy, Japan, Canada, and Taiwan) announced the discovery of the Top Quark: it has a mass of 175 GeV (it weighs as much as a gold atom!) One of the last pieces of the Standard Model falls into place. Standard Model: 6 quarks (up, down, charm, strange, top or truth, bottom or beauty), 6 leptons (electron neutrino, electron, muon neutrino, muon, tau neutrino, and tau), and gauge bosons for the four forces: a photon for the electromagnetic force, W-, W+, and Z0 for the weak force, 8 gluons for the strong force, and the (undiscovered) graviton for gravity. The discovery of the Top Quark, like that of other fundamental particles, such as the Higgs Boson, is not in reality a “Eureka event” that happens suddenly, but a patient collection of data that lasts months or years, in order to reach the necessary statistical evidence (5-sigma).

The Budapest Memorandum, signed in the Homeland Hall of the Budapest Congress Center in the presence of, among others, US Ambassador Donald M. Blinken, prohibits Russia, the United States, and the United Kingdom from threatening or using military force or economic coercion against Ukraine, Belarus, and Kazakhstan, “except in self-defense or otherwise in accordance with the Charter of the United Nations.” Following other agreements and the memorandum, between 1993 and 1996, Belarus, Kazakhstan, and Ukraine renounced their nuclear weapons. The Ukrainian government, under Western pressure, completed the destruction or handed over to Russia of the Soviet nuclear weapons still stationed on its territory on October 30, 2001, and destroyed its own nuclear-capable bombers. Had it not done so, would Russia have invaded Ukraine first in 2014 and then again in 2022? At the time, the Soviet arsenal in Ukrainian hands was the third largest in the world.

With the sudden collapse of the USSR in August 1991, even its flagship was at risk of being dismantled: the military-industrial complex with 600,000 workers, engineers, and scientists. The $4 billion budget in 1989 collapsed to $0.7 billion in 1994, and thousands of prestigious technicians emigrated to the West. Worse still, Oleg Baklanov, head of the space industry, had the brilliant idea of joining the group that carried out the attempted coup in 1991. The obvious consequence was a certain government distrust of the space industry. But the sector did not disappear; on the contrary, it recovered, and today Russia remains one of only three nations that can send people into space.

Russia. The Rockot (diamond) launcher is derived from the Soviet SS-19 ICBM (Vladimir Chelomei’s UR-100). In the USSR, there were 360 SS-19 Stilettos ready in silos, and another 144 were launched as tests. The first orbital mission took place on December 26, 1994. It launched 2 tons into LEO for $14 million. It used UDMH (hypergolic hydrazine). The launch sites at Baikonur were all silos, which caused enormous noise and vibration during launch. They were therefore moved to Plesetsk. In 1995, Khrunichev formed a company with Daimler-Benz, called Eurockot, and then Astrium GmbH, a shareholder of Arianspace, joined in 2000. It can reignite its final stage six times, deploying multiple satellites. It will be retired after the last launch on December 26, 2019, after 34 launches and 31 successes.

US forces land in Haiti. 20,000 US troops landed without resistance in Haiti to oversee the country’s democratic transition. In 1991, during a bloody military coup, Roman Catholic priest Jean-Bertrand Aristide, Haiti’s first freely elected president, was deposed and fled into exile. A triumvirate assumed power. In 1994, in response to proven atrocities committed by the military dictatorship, the UN authorized the use of force to reinstate Aristide. But on September 18, the eve of the invasion, a diplomatic delegation led by former President Jimmy Carter brokered a last-minute agreement by which the Haitian military government relinquished power. This prevented any bloodshed, and on October 15, Aristide returned to Haiti. Aristide remained in office until the end of his term in 1996. In 2000, he was re-elected in elections marred by violence and corruption.

North Korea’s “great leader” dies. Kim Il Sung, dictator of North Korea since 1948, dies of a heart attack at the age of 82. In the 1930s, he fought against the Japanese invasion and, at the recommendation of Soviet authorities, traveled to the USSR for political and military training. A convert to communism, he joined the Red Army and fought in World War II. In 1945, Korea was divided into two spheres of influence, American and Soviet, and in 1948, Kim became the first president of the Democratic People’s Republic of Korea (North Korea). Hoping to reunify the country by force, Kim ordered an invasion of the South in 1950, sparking the so-called Korean War, which ended in 1953 with no results. For the next 40 years, Kim ruled the country in profound isolation, even distancing himself from his former communist allies, and tensions with the South continued unabated. Through repression and a personality cult, the “great leader” maintained power until his death. He was succeeded by his son Kim Jong Il.

After the end of the Cold War, nuclear deterrence no longer held up in international comparisons and new approaches to the conduct of war took hold. Particularly after the failed military intervention in Somalia in support of humanitarian operations, the United States adopted the Powell Doctrine, derived from the Weinberger Doctrine, which calls for the use of overwhelming force to achieve a quick victory and lose the fewest possible American lives. The purpose of the use of military force must be limited to battlefield operations, without involvement in peacekeeping operations. The doctrine was applied effectively in Kuwait (1991) and Kosovo (1999), but not at all in Iraq (2003–2011) and Afghanistan (2001–2015). The doctrine was ratified by Presidential Directive 25. European nations adopted the opposite view: military forces are used with the declared purpose of peacekeeping operations or peacekeeping, or to ensure nation-building.
