The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 7 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Strogatz: Math revealed HIV produces a billion virus particles daily
“By making measurements on the rate of this exponential drop Perelson and Ho were able to show that the body HIV was producing about a billion virus particles every day. HIV was making an enormous amount of new virus, and the immune system was clearing it out a…”
Strogatz: Mathematical modeling proved three-drug therapy suppresses long-term HIV mutations
“What Perilson's math showed is that if you did two drugs, your odds were a little better, because then the virus would have to do two simultaneous mutations. The odds of that were lower than one. But three drugs would be the sweet spot where The odds were so l…”
Strogatz: In taxicab geometry, pi equals four
“If you calculate the circumference and you calculate the diameter, you'll end up getting that they're always in the ratio. I think I'm doing it right. It's always going to be four times the diameter will be the circumference, which is interesting that pi is, i…”
Strogatz: GPS would fail within 20 minutes without Einstein's relativistic corrections
“If we didn't build in the Einsteinian corrections to timekeeping, the whole GPS system would fall apart in about 20 minutes. It would, it wouldn't be able to keep accurate time.”
Strogatz: All electrons in the universe are identical and never age
“Any two electrons anywhere in the universe are absolutely indistinguishable. There is no diversity of subatomic particles. I mean, they're different particles. Electrons are different from protons, but every electron is completely the same in every respect as …”
Strogatz: Winning game theory strategies are nice, forgiving, retaliatory, and clear
“What he found when he ran these tournaments of all these programs playing against each other he found that the programs that tended to do well in the tournament had four properties in common, and he summarized these four properties by saying that first, they w…”
