Supra Rank of the Countries in the Olympic Games

It has been shown that the best way how to rank the Olympic achievements of the countries is to take the average of two ranks: one based on the medal number and the other on the medal number per capita, providing "supra rank". The medal number is well summed by medal points: S1 [= G + S/2 + B/3, where G, S, and B are the number of gold, silver, and bronze medals,

Ranking the countries according to the number of gold medals in 2012 London Olympics, or according to the number of all medals, or according to the medal points (gold + 1/2 silver + 1/3 bronze), respectively, provides the following sequences:

The question is always how to rank the countries according to their achievements in sports. The following table includes 84 countries which gained at least one medal in London 2012 Olympics. The first column shows the number of gold medals (G), the second column shows the number of all medals (M), the third column shows the sum (S) of [gold + silver/2 + bronze/3] medal points, the fourth column shows the country population (P) in millions, and the fifth column shows the medal points per capita

Current Events for the Future History

June 19, 2018 The Trump administration withdraws from the United Nations Human Rights Council, denoted by the U.S. ambassador to the UN, Nikki Haley, as “a protector of human rights abusers, and a cesspool of political bias”.
June 12, 2018 North Korean leader Kim Jong Un and US president Trump meet in Singapore to negotiate nuclear demilitarization – a feat of Trump, resulting from his non-compromising politics.
March 2018 A former Russian intelligence official, Sergei Skripal, and his daughter are poisoned with the nerve agent novichok in England. In a united European response, 100 Russian diplomats are expelled from 20 countries as a punishment for the aggressive and dangerous act.
February 2018 US president Trump announces recognition of Jerusalem as the capital of Israel, and relocation the U.S. embassy there from Tel Aviv by 70^th anniversary of Israel independence day in May.

No Need to Panic About Energy Need

Thermonuclear fusion will provide a nearly unlimited amount of energy for the world; ITER will be the first fusion experiment to produce net power by 2040 (www.iter.org).
Methane hydrates (methane/water clathrate) form massive deposits on the seafloor surrounding all continents and may hold more energy than all known reserves of oil, coal and natural gas worldwide (Sci. Am. October 2014, p. 71). Japan plans to commercially utilize the material, possibly equaling 2,000 years of natural gas supply at the current consumption rate, by 2016.
Shale oil can be environmentally safely extracted, and in the U.S. it can provide more energy than normal oil for decades (Sci. Am. November 2011, p. 62).
Known oil sources will provide more oil than predicted due to advanced technologies, increasing the predicted reserves by at least another century; however, the estimated reserves may still increase as they have been increasing throughout the history (Sci. Am. October 2009, p. 36).
Uranium reserves can provide world energy for at least 2,000 years (Vesmír 2008/11, p. 796).

Fragments from Science and Life

Male homosexuality is correlated with maternal immune responsivity to the Y-linked protein NLGN4Y. Mothers form an antibody against a protein important in male fetal brain development, neuroligin 4, located on sex chromosomes, the effect becomes increasingly likely with each male gestation, altering brain structures underlying sexual orientation in their later-born sons. One of the most reliable correlates of male homosexuality – older brothers – is thus explained (PNAS, December 2017). This is the first case of a clear correlation between the sexual orientation and a biochemical factor.
Placebo effect is significant also for operations. A British study has now showed that there was no difference between 100 patients getting a stent in their blocked artery and 100 patients getting a sham surgery (Lancet, November 2017; SciAm, February 2018). The real and fake surgeries included snaking a catheter through an artery in the groin to the blockage with or without a step of widening the narrowed vessel and keeping it open with wire mesh stent. This operation is widely popular, but now it turns out that dugs with lifestyle changes are preferable to the operation. In a meta-analysis of placebo effects in migraine prevention, sugar pills reduced headache frequency for 22% patients, acupuncture for 38% and sham surgery for 58%.
Humans can hold underwater for more than 12 minutes due to mammalian diving reflex, which is common to many vertebrates like dolphins and penguins (see deep diving). The reflex is triggered by cold water and results in drop in heart rate and blood redistribution towards vital organs by means of vasoconstriction; it can override a breathing reflex. This potential we acquired long ago in the evolution can be utilized by practicing, and probably can explain stories about children fallen into a cold well and surviving “a near drowning” for a long time under water.
